OBJECTIVE: To assess asthma patients in Brazil in terms of the level of asthma control, compliance with maintenance treatment, and the use of rescue medication. METHODS: We used data from a Latin American survey of a total of 400 asthma patients in four Brazilian state capitals, all of whom completed a questionnaire regarding asthma control and treatment. RESULTS: In that sample, the prevalence of asthma was 8.8%. Among the 400 patients studied, asthma was classified, in accordance with the Global Initiative for Asthma criteria, as controlled, partially controlled, and uncontrolled in 37 (9.3%), 226 (56.5%), and 137 (34.3%), respectively. In those three groups, the proportion of patients on maintenance therapy in the past four weeks was 5.4%, 19.9%, and 41.6%, respectively. The use of rescue medication was significantly more common in the uncontrolled asthma group (86.9%; p < 0.001). CONCLUSIONS: Our findings suggest that, in accordance with the established international criteria, asthma is uncontrolled in the vast majority of asthma patients in Brazil. Maintenance medications are still underutilized in Brazil, and patients with partially controlled or uncontrolled asthma are more likely to use rescue medications and oral corticosteroids.

To investigate the relationship between use of asthma medication and nitrates and risk of reflux oesophagitis, Barrett's oesophagus and oesophageal adenocarcinoma. Data were collected on use of asthma medication and nitrates at least 1 year before interview from patients with reflux oesophagitis, Barrett's oesophagus and oesophageal adenocarcinoma. Associations between use of asthma medications and nitrates and the risk of reflux oesophagitis, Barrett's oesophagus and oesophageal adenocarcinoma were estimated using multiple logistic regression. Nine hundred and forty-one subjects were recruited: 230 reflux oesophagitis, 224 Barrett's oesophagus, 227 oesophageal adenocarcinoma patients and 260 population controls. Barrett's oesophagus patients were more likely than controls to have had a diagnosis of asthma (odds ratio 2.15, 95% confidence interval 1.15-4.03) and to have used asthma medications (odds ratio 2.13, 95% confidence interval 1.09-4.16). No significant associations were observed between use of asthma medication or nitrates and reflux oesophagitis or oesophageal adenocarcinoma. Gastro-oesophageal reflux symptoms appear to confound the association between asthma medication use and Barrett's oesophagus. However, it is possible that asthma medications may increase the risk of Barrett's oesophagus by other mechanisms.

Medication use-related issues remain problematic in childhood asthma despite effective treatment strategies and public investment into improved asthma management strategies in industrialized countries. This study aimed to carry out an in-depth exploration of the views of parents/carers and children with asthma on medication use. Semi-structured qualitative interviews were conducted with a purposive convenience sample of children with asthma and their parents recruited from general practices in Sydney. Interviews were tape-recorded, transcribed verbatim, and thematically analyzed. A total of 52 interviews (26 parents/carers and 26 children with asthma) were conducted. Major themes which emerged from the children's interviews included issues such as self-image, resistance to medication use, and lack of responsibility in medication taking. Parental or carer issues included lack of clear understanding of how medications worked, as well as administration difficulties, cost constraints, and beliefs about medications contrary to quality use. This is one of the few research studies exploring the viewpoint of children with asthma about their medications in Australia. Despite investment in dissemination of professional, targeted evidence-based asthma management strategies in healthcare, there seems to be a lack of depth in terms of what parents understand about their child's asthma. Effective communication about medication usage, especially the inclusion of the child in the consultation to empower them to be involved in their own asthma care, may be the answer.

Very little is known about the burden of asthma in Vietnamese American children. Prior data have suggested that the burden of childhood asthma is significant for this population, although they seem to underutilize Western healthcare for unclear reasons. To gain insight into the perceptions of the burden, health needs, and traditional health beliefs regarding childhood asthma in the Vietnamese American community in Orange County, CA. Additionally, to foster and build sustainable relationships with the community and to ensure that our research process is mutually rewarding for all stakeholders. Using a community-based participatory research (CBPR) approach, we initiated the formation of the Vietnamese Children's Asthma Project (VCAP) and used focus groups of various community stakeholders as a platform to gather information, give basic asthma education, and build relationships. A total of 66 people participated in the focus groups: 26 parents, 20 Vietnamese American physicians, 12 school nurses, and 8 school-community liaisons (SCLs). Overall, all participants believe that asthma is a significant problem and that language is a barrier to healthcare access for the Vietnamese community. We learned that academic achievement is a high priority for Vietnamese parents and associating better asthma control with improved academic performance may be a way to improve asthma education and adherence with therapy. We also found that although healthcare providers believe that parental traditional beliefs contribute to non-adherence to Western therapies, Vietnamese American parents report that they prefer to use Western medications to treat their children's asthma. Through the use of CBPR and the development of VCAP, we successfully conducted focus groups to assess the Vietnamese American perception of the burden of childhood asthma in their community and to gauge their receptivity to participate in further studies about childhood asthma and receptivity to subsequent interventions.

The objective was to investigate the association between receiving care under the medical home model and parental assessment of the severity of asthma symptoms. It was hypothesized that parents of children who received care under the medical home model reported less severe asthma symptoms compared with their counterparts, whose care did not meet the medical home criteria. Secondary analyses were conducted using cross-sectional data from the 2011-2012 National Survey of Children's Health. Children with asthma aged 0-17 years were included and classified as receiving care from the medical home if their care contained 5 components: a personal doctor, a usual source of sick care, family-centered care, no problems getting referrals, and effective care coordination. Ordinal logistic regression was used to examine the relationship between parent-rated severity of asthma symptoms (mild, moderate, and severe symptoms) and the medical home. Approximately 52% of 8229 children who reported having asthma received care from the medical home. Only 30.8% of children with severe asthma symptoms received care that met the medical home criteria, compared to 55.7% of children with mild symptoms. After accounting for confounding factors, obtaining care under the medical home model decreased the odds of parent-reported severe asthma symptoms by 31% (adjusted odds ratio 0.69; 95% CI, 0.56-0.85). Study results suggest that the medical home model can reduce parent-rated severity of asthma symptoms. The findings highlight the importance of providing medical home care to children with asthma to improve the outcomes that matter most to children and their families.

The relative performance of asthma care quality measures has not been evaluated in Medicaid populations. Using complete claims and pharmaceutical data for 19,076 patients with persistent asthma (based on Health Effectiveness and Data Information Set criteria) in five Medicaid populations, we compared the following two measures of asthma care quality: filling prescriptions for controller asthma medications within 1 year and the ratio of controller medication to the total number of asthma medication prescriptions filled within 1 year. We calculated whether meeting each quality measure was associated with decreased odds of emergency department (ED) treatment episodes. We then compared the odds ratios, receiver operating characteristic (ROC) curves, and deviances between models, using each measure to predict ED utilization in Medicaid populations. Although meeting each measure was associated with lower odds of ED utilization, this decrease was larger if the controller asthma medication measure was met rather than the ratio measure. Additionally, models using the controller medication measure had greater areas under the ROC curve and smaller deviances than models using the ratio measure. Both administrative measures of asthma care quality were associated with lower odds of ED utilization. The controller medication measure of asthma care quality may be better than the ratio measure in relation to emergency asthma care utilization by Medicaid beneficiaries.

For medically treated asthma, we estimated prevalence, medical and absenteeism costs, and projected medical costs from 2015 to 2020 for the entire population and separately for children in the 50 US states and District of Columbia (DC) using the most recently available data. We used multiple data sources, including the Medical Expenditure Panel Survey, U.S. Census Bureau, Kaiser Family Foundation, Medical Statistical Information System, and Current Population Survey. We used a two-part regression model to estimate annual medical costs of asthma and a negative binomial model to estimate annual school and work days missed due to asthma. Per capita medical costs of asthma ranged from $1,860 (Mississippi) to $2,514 (Michigan). Total medical costs of asthma ranged from $60.7 million (Wyoming) to $3.4 billion (California). Medicaid costs ranged from $4.1 million (Wyoming) to $566.8 million (California), Medicare from $5.9 million (DC) to $446.6 million (California), and costs paid by private insurers ranged from $27.2 million (DC) to $1.4 billion (California). Total annual school and work days lost due to asthma ranged from 22.4 thousand (Wyoming) to 1.5 million days (California) and absenteeism costs ranged from $4.4 million (Wyoming) to $345 million (California). Projected increase in medical costs from 2015 to 2020 ranged from 9% (DC) to 34% (Arizona). Medical and absenteeism costs of asthma represent a significant economic burden for states and these costs are expected to rise. Our study results emphasize the urgency for strategies to strengthen state level efforts to prevent and control asthma attacks.

Improving asthma care in emergency departments: results of a multihospital collaborative quality initiative in rural western North Carolina.

In North Carolina, nearly one-fourth of persons with asthma visit an emergency department (ED) or urgent care center at least once a year because of an exacerbation of asthma symptoms. The Emergency Department Asthma Program was a quality-improvement initiative designed to better understand the population of patients who use the ED for asthma care in rural western North Carolina and to demonstrate whether EDs at small hospitals could, by implementing National Asthma Education and Prevention Program treatment guidelines, improve asthma care and reduce subsequent asthma-related ED visits. Eight hospitals in western North Carolina participated in the project, which lasted from November 2003 through December 2007. The intervention consisted of a series of individual and structured continuing medical education events directed at ED physicians and staff. Additionally, patients presenting to EDs for asthma-related problems were selected to receive a short patient questionnaire, to determine their basic understanding of asthma and barriers to asthma care; to undergo asthma staging by the treating physician; to receive focused bedside asthma education by a respiratory therapist; and, finally, at the treating physician's discretion, to receive a free packet of asthma medications, including rescue therapy with a beta-agonist and corticosteroid therapy delivered via a metered-dose inhaler, before discharge. During the 37-month project, a total of 1,739 patients presented to the participating EDs for 2,481 asthma-related episodes of care; at 11% of these visits, patients received the intervention, with nearly 100 ED physicians referring patients to the program. Most of the patients using the ED for asthma treatment were judged to have the mildest stages, and nearly half were uninsured or were covered by Medicaid. For only 20% of the visits was a primary care physician or practice identified. The patient intervention did not appear to lessen the rate of return visits for asthma-related symptoms at 30 and 60 days. Selection bias is likely, as patients enrolled in the study were more likely than patients in the target sample to be adults and insured. Because we did not measure ED staff attendance at educational sessions or their knowledge of and attitudes about asthma care before and after the educational program, we cannot draw conclusions about the effectiveness of the program to change their knowledge, attitudes, or behavior. Many patients who use the ED for care appear to have mild, intermittent asthma and do not identify a regular source of primary care. Efforts to improve asthma care on a communitywide basis and to reduce preventable exacerbations should include care provided in EDs, as this may be the only source of asthma care for many asthma patients. The project demonstrated that regional, collaborative performance improvement efforts in EDs are possible but that many barriers exist to this approach.

Background Multiple issues bear on effective control of childhood asthma. Objective To identify factors related to the level of asthma control in children receiving asthma care from community pediatricians. Patients and Methods Data for 362 children participating in an intervention study to reduce asthma morbidity were collected by telephone administered questionnaire. Level of asthma control (“well controlled,” partially controlled,” or “poorly controlled”) was derived from measures of recent impairment (symptoms, activity limitations, albuterol use) and the number of exacerbations in a 12 month period. Data also included demographic characteristics, asthma-related quality of life, pediatric management practices, and medication usage. Univariable and multivariable analyses were used to identify factors associated with poor asthma control and to explore the relationship between control and use of daily controller medications. Results Asthma was “well controlled” for 24% of children, “partially controlled” for 20%, and “poorly controlled” for 56%. Medicaid insurance (p=0.016), the presence of another family member with asthma (p=0.0168), and outside the home maternal employment, (p=0.025), were significant univariable factors associated with poor asthma control. Medicaid insurance had an independent association with poor control (OR 0.49, 95% CI 0.28-0.9). Seventy-six percent of children were reported by parents as receiving a daily controller medication. Comparison of guidelines recommended controller medication with level of control indicated that a higher step level of medication would have been appropriate for 74% of these children. Significantly lower overall quality of life scores were observed in both parents and children with poor control. (ANOVA, p<0.05) Conclusion Despite substantial use of daily controller medication, children with asthma continue to experience poorly controlled asthma and reduced quality of life. While Medicaid insurance and aspects of family structure are significant factors associated with poorly controlled asthma, attention to medication use and quality of life indicators may further reduce morbidity.

To determine whether diagnosis and treatment of paradoxical vocal fold movement disorder (PVFMD) leads to decreased asthma medication use. Secondary objectives include determining initial rate of asthma medication use, characterizing symptom improvement, and correlating with pulmonary function testing (PFT). Prospective observational study. Patients newly diagnosed with PVFMD at a single institution were recruited to participate. Medication questionnaires were completed at the initial visit, at the first return visit for therapy, and at 6 months. PFTs were reviewed when available. Sixty-six patients were recruited; the study was closed early because findings reached significance. Fifty-six patients (85%) were taking asthma medication at presentation. Forty-four patients presented with PFTs, and two-thirds were normal. Forty-two patients completed follow-up questionnaires; 79% decreased asthma medication use (P < .001), and 82% reported symptom improvement. Seventy-seven percent of patients participated in therapy and 23% did not, with equal rates of decrease in asthma medication use between these groups. Outcomes did not vary based on PFT pattern (i.e., obstructive vs. nonobstructive, P = .75). Diagnosis and treatment of PVFMD lead to a decline in asthma medication use. This decrease occurred alongside symptom improvement and irrespective of PFT findings. Use of asthma medication in this patient population is high, at 85%. 4.

Asthma and attention-deficit/hyperactivity disorder (ADHD) are prevalent in childhood and may cause functional impairment and stress in families. Previous research supports an association between asthma and ADHD in children, but several aspects of this relationship are unclear. Our aim was to study whether the association between asthma and ADHD is restricted to either the inattentive or the hyperactive/impulsive symptoms of ADHD, to explore the impact of asthma severity and asthma medication and the contribution of shared genetic and environmental risk factors on the asthma-ADHD relationship. Data on asthma, ADHD, zygosity and possible confounders were collected from parental questionnaires at 9 or 12 years on 20 072 twins through the Swedish Twin Register, linked to the Swedish Medical Birth Register, the National Patient Register and the Prescribed Drug Register. The association between asthma and ADHD, the impact of asthma severity and medication, was assessed by generalized estimating equations. Cross-twin-cross-trait correlations (CTCT) were estimated to explore the relative importance of genes and environment for the association. Asthmatic children had a higher risk of also having ADHD [odds ratio (OR) 1.53, 95% confidence interval (CI): 1.16-2.02]. The association was not restricted to either of the two dimensions of ADHD. The magnitude of the association increased with asthma severity (OR 2.84, 95% CI: 1.86-4.35) for ≥ 4 asthma attacks in the last 12 months and was not affected by asthma treatment. The CTCTs possibly indicate that the genetic component in overlap of the disorders is weak. Childhood asthma, especially severe asthma, is associated with ADHD. Asthma medication seems not to increase the risk of ADHD. Clinicians should be aware of the potential of ADHD in asthma. Optimal asthma care needs to be integrated with effective evaluation and treatment of ADHD in children with co-existing disorders. © 2015 John Wiley & Sons Ltd.

Asthma often begins early in childhood. However, the risk for persistence is challenging to evaluate. This longitudinal study relates lung function assessed with impulse oscillometry (IOS) in preschool children to asthma in adolescence. Lung function was measured with IOS in 255 children with asthma-like symptoms aged 4-7 years. Baseline measurements were followed by exercise challenge and bronchodilation tests. At age 12-16 years, 121 children participated in the follow-up visit, when lung function was assessed with spirometry, followed by a bronchodilation test. Asthma symptoms and medication were recorded by a questionnaire and atopy defined by skin prick tests. Abnormal baseline values in preschool IOS were significantly associated with low lung function, the need for asthma medication, and asthma symptoms in adolescence. Preschool abnormal R5 at baseline (z-score ≥1.645 SD) showed 9.2 odds ratio (95%CI 2.7;31.7) for abnormal FEV1/FVC, use of asthma medication in adolescence, and 9.9 odds ratio (95%CI 2.9;34.4) for asthma symptoms. Positive exercise challenge and modified asthma-predictive index at preschool age predicted asthma symptoms and the need for asthma medication, but not abnormal lung function at teenage. Abnormal preschool IOS is associated with asthma and poor lung function in adolescence and might be utilised for identification of asthma persistence. Copyright © 2018 The Authors.

Limited health literacy is associated with low adherence to asthma controller medications among older adults. We sought to describe the causal pathway linking health literacy to medication adherence by modeling asthma illness and medication beliefs as mediators. We recruited adults aged 60 years and older with asthma from hospital and community practices in New York, New York, and Chicago, Illinois. We measured health literacy and medication adherence using the Short Test of Functional Health Literacy in Adults and the Medication Adherence Rating Scale, respectively. We used validated instruments to assess asthma illness and medication beliefs. We assessed cognition using a cognitive battery. Using structural equation modeling, we modeled illness and medication beliefs as mediators of the relationship between health literacy and adherence while controlling for cognition. Our study included 433 patients with a mean age of 67 ± 6.8 years. The sample had 84% women, 31% non-Hispanic blacks, and 39% Hispanics. The 36% of patients with limited health literacy were more likely to have misconceptions about asthma (P < .001) and asthma medications (P < .001). Health literacy had a direct effect (β = 0.089; P < .001) as well as an indirect effect on adherence mediated by medications concerns (β = 0.033; P = .002). Neither medication necessity (β = 0.044; P = .138) nor illness beliefs (β = 0.007; P = .143) demonstrated a mediational role between health literacy and adherence. Interventions designed to improve asthma controller medication adherence in older adults may be enhanced by addressing concerns about medications in addition to using communication strategies appropriate for populations with limited health literacy and cognitive impairments.

Circadian rhythms in the pharmacokinetics and clinical effects of beta-agonist, theophylline, and anticholinergic medications in the treatment of nocturnal asthma.

1999-09-01

Published asthma consensus reports now acknowledge that asthma is a nocturnal disease in as many as 75% of those afflicted by this medical condition. Nonetheless, the treatment of this chronic obstructive pulmonary disease in the clinic continues to be based primarily on homeostatic considerations in that it relies on long-acting bronchodilator and other therapies formulated and scheduled to ensure constant or near-constant levels of medication during the 24h. The need of asthma patients prone to nighttime attacks is not the same during the day and night; the therapeutic requirements of patients who experience nocturnal asthma, especially ones with the more severe forms of the disease, are often not satisfied by conventional medications. The therapeutic response and patient tolerance to bronchodilator medications can be improved markedly when the medications are proportioned during the 24h as a chronotherapy, that is, when more medication is delivered during nighttime sleep than daytime activity, as verified by numerous studies. This article reviews how the body's circadian rhythms influence the pharmacokinetics and effects of commonly prescribed asthma therapies and addresses why and how they must be taken into consideration to increase the effectiveness of asthma treatment.

Nonprescription bronchodilator medication use in asthma.

1997-10-01

Many persons with asthma self-medicate with widely available and potentially hazardous nonprescription medicines. This study assessed the demographic and clinical covariates of self-treatment with over-the-counter asthma medications (OTCs). We conducted an analytical investigation using questionnaires and measures of lung function, comparing OTC and prescription medication users. We recruited adults with asthma by public advertisement. We studied 22 exclusive prescription asthma medication users, 15 exclusive OTC users, and 13 other subjects who combined prescription medication use with self-treatment with asthma OTCs. All but one OTC user self-medicated with a nonselective, sympathomimetic metered-dose inhaler. Taking income, access to care, and self-assessed disease severity into account, male gender was strongly associated with exclusive OTC use alone (odds ratio [OR]=8.9, 95% confidence interval [CI]= 1.3 to 61) and mixed OTC-prescription medication use (OR=9.7, 95% CI=1.1 to 83). The covariates of income, access to care, and self-assessed disease severity provided significant additional explanatory power to the model of exclusive OTC use (model chi2 difference 11.3, 5 df, p<0.05). Pulmonary function was similar among OTC and prescription medication users. However, prescription medication users' self-assessed asthma severity (mild compared to more severe) was associated with postbronchodilator reversibility of FEV1 obstruction (6% vs 18% reversibility, p<0.05) while exclusive OTC users' self-assessed severity showed the reverse pattern (19% vs 8%, p=0.2). Asthma education programs attempting to discourage unregulated bronchodilator use should give consideration to this profile of the "asthmatic-at-risk."

Asthma medication adherence is low, particularly among Medicaid enrollees. There has been much debate on the impact of direct-to-consumer advertising (DTCA) on health care use, but the impact on medication use among children with asthma has been unexamined. The study sample included 180,584 children between the ages of 5 and 18 with an asthma diagnosis from a combined dataset of Medicaid Analytic eXtract and national advertising data. We found that DTCA expenditure during the study period was significantly associated with an increase in asthma medication use. However, the effectiveness declined after a certain level.

Self-hypnosis for anxiety associated with severe asthma: a case report

PubMed Central

Anbar, Ran D

2003-01-01

Background Management of asthma can be complicated by both medical and psychiatric conditions, such as gastroesophageal reflux, chronic sinusitis, and anxiety. When symptoms of asthma are interpreted without regard to such conditions treatment may yield a suboptimal outcome. For example, anxiety-associated dyspnea, tachypnea, and chest tightness can be mistakenly interpreted as resulting from an exacerbation of asthma. Medical treatment directed only for asthma may thus lead to overuse of asthma medications and increased hospitalizations. Case Presentation The described case illustrates how a systemic steroid-dependent patient with asthma benefited from receiving care from a pediatric pulmonologist who also was well versed in the diagnosis and treatment of anxiety. By using self-hypnosis, the patient was able to reduce her dependence on bronchodilators. Following modification of her medical therapy under supervision of the pulmonologist, and regular use of hypnosis, the patient ultimately was weaned off her systemic steroid therapy. Conclusions This report emphasizes that anxiety must be considered as a comorbid condition in the treatment of asthma. Self-hypnosis can be a useful skill in the treatment of a patient with anxiety and asthma. PMID:12875663

Background Parent-healthcare provider (HCP) communication is an important component of pediatric asthma management. Given the high prevalence of complementary and alternative medicine (CAM) and over-the-counter (OTC) medication use among this population, it is important to examine parental nondisclosure of these asthma management strategies. Method One-time interview and one-year retrospective medical record review with 228 parents of 5–12 year old children with asthma enrolled from 6 pediatric primary care practices examining parental nondisclosure of CAM and OTC medication use, reasons for nondisclosure, medical record documentation of CAM usage, and association between parent-HCP relationship and nondisclosure. Results Seventy-one percent of parents reported using CAM and/or OTC medication for children’s asthma management and 54% of those parents did not disclose usage. Seventy-five percent “did not think” to discuss it. Better parent-HCP relationship led to decreased nondisclosure. Discussion HCPs can play an important role in creating an environment where parents feel comfortable sharing information about their children’s asthma management strategies in order to arrive at a shared asthma management plan for the child leading to improved asthma health outcomes.

The relative contributions of genetics and environment to asthma in Hispanics or to asthma in children younger than 3 years are not well understood. To examine the relative contributions of genetics and environment to early-childhood asthma by performing a longitudinal twin study of asthma in Puerto Rican children ≤ 3 years old. 678 twin infants from the Puerto Rico Neo-Natal Twin Registry were assessed for asthma at age 1 year, with follow-up data obtained for 624 twins at age 3 years. Zygosity was determined by DNA microsatellite profiling. Structural equation modeling was performed for three phenotypes at ages 1 and 3 years: physician-diagnosed asthma, asthma medication use in the past year, and ≥ 1 hospitalization for asthma in the past year. Models were additionally adjusted for early-life environmental tobacco smoke exposure, sex, and age. The prevalences of physician-diagnosed asthma, asthma medication use, and hospitalization for asthma were 11.6%, 10.8%, 4.9% at age 1 year, and 34.1%, 40.1%, and 8.5% at 3 years, respectively. Shared environmental effects contributed to the majority of variance in susceptibility to physician-diagnosed asthma and asthma medication use in the first year of life (84%-86%), while genetic effects drove variance in all phenotypes (45%-65%) at age 3 years. Early-life environmental tobacco smoke, sex, and age contributed to variance in susceptibility. Our longitudinal study in Puerto Rican twins demonstrates a changing contribution of shared environmental effects to liability for physician-diagnosed asthma and asthma medication use between ages 1 and 3 years. Early-life environmental tobacco smoke reduction could markedly reduce asthma morbidity in young Puerto Rican children.

Asthma affects a considerable proportion of the population worldwide and presents a significant health problem in Australia. Given its chronic nature, effective asthma self-management approaches are important. However, despite research and interventions targeting its treatment, the management of asthma remains problematic. This study aimed to develop, from a theoretical basis, an asthma self-management model and implement it in an Australian community pharmacy setting in metropolitan Sydney, using a controlled, parallel-groups repeated-measures design. Trained pharmacists delivered a structured, step-wise, patient-focused asthma self-management program to adult participants over a 9-month period focusing on identification of asthma problems, goal setting and strategy development. Data on process- clinical- and psychosocial-outcome measures were gathered. Results showed that participants set an average of four new goals and six repeated goals over the course of the intervention. Most common goal-related themes included asthma triggers, asthma control and medications. An average of nine strategies per participant was developed to achieve the set goals. Common strategies involved visiting a medical practitioner for review of medications, improving adherence to medications and using medications before exercise. Clinical and psychosocial outcomes indicated significant improvements over time in asthma symptom control, asthma-related self-efficacy and quality of life, and negative affect. These results suggest that an asthma self-management model of illness behaviour has the potential to provide patients with a range of process skills for self-management, and deliver improvements in clinical and psychosocial indicators of asthma control. The results also indicate the capacity for the effective delivery of such an intervention by pharmacists in Australian community pharmacy settings.

Teens with persistent asthma do not always receive daily preventive medications or do not take them as prescribed, despite established clinical guidelines. The purpose of this study was to understand urban teens' experiences with asthma management, preventive medication adherence and participation in a school-based intervention. Teens (12-15 years) with persistent asthma, and prescribed preventive medication, participated in a pilot study that included daily observed medication therapy at school and motivational interviewing. Semi-structured interviews occurred at final survey. Qualitative content analysis enabled data coding to identify themes. Themes were classified as "general asthma management" or "program-specific." For general management, routines were important, while hurrying interfered with taking medications. Forgetfulness was most commonly linked to medication nonadherence. Competing demands related to school preparedness and social priorities were barriers to medication use. Independence with medications was associated with several benefits (e.g. avoiding parental nagging and feeling responsible/mature). Program-specific experiences varied. Half of teens reported positive rapport with their school nurse, while a few felt that their nurse was dismissive. Unexpected benefits and barriers within the school structure included perceptions about leaving the classroom, the distance to the nurse's office, the necessity of hall passes and morning school routines. Importantly, many teens connected daily medication use with fewer asthma symptoms, incenting continued adherence. Teens with asthma benefit from adherence to preventive medications but encounter numerous barriers to proper use. Interventions to improve adherence must accommodate school demands and unique teen priorities. The school nurse's role as an ally may support teens' transition to medication independence.

The global burden of pediatric asthma is high. Governments and health-care systems are affected by the increasing costs of childhood asthma--in terms of direct health-care costs and indirect costs due to loss of parental productivity, missed school days, and hospitalizations. Despite the availability of effective treatment, the current use of medications in children with asthma is suboptimal. The purpose of this review is to scope the empirical literature to identify the problems associated with the use of pediatric asthma medications. The findings will help to design interventions aiming to improve the use of asthma medications among children. A literature search using electronic search engines (i.e., Medline, International Pharmaceutical Abstracts (IPA), PubMed, PsycINFO, and Cumulative Index to Nursing and Allied Health Literature (CINAHL)) and the search terms "asthma," "children," and "medicines" (and derivatives of these keywords) was conducted. The search terms were expanded to include emergent themes arising out of search findings. Content themes relating to parents, children themselves, health-care professionals, organizational systems, and specific medications and devices were found. Within these themes, key issues included a lack of parental knowledge about asthma and asthma medications, lack of information provided to parents, parental beliefs and fears, parental behavioral problems, the high costs of medications and devices, the child's self-image, the need for more child responsibility, physician nonadherence to prescribing guidelines, "off-label" prescribing, poor understanding of teachers, lack of access to educational resources, and specific medications. These key issues should be taken into account when modifying the development of educational tools. These tools should focus on targeting the children themselves, the parent/carers, the health-care professionals, and various organizational systems.

Despite the high prevalence of asthma in children, there has been limited research into patient perception of medication use, particularly in the developing world. This study therefore aimed to carry out an in-depth exploration of the views of carers and children with asthma on asthma medication use. Grounded theory approach was used to conduct semistructured qualitative interviews in a purposive convenience sample of parents and children with asthma. The participants were recruited from two specialty hospitals in New Delhi, India. Interviews were tape-recorded, transcribed verbatim and thematically analysed. Twenty children (7-12 years old) with asthma and their parent or carer were interviewed in July 2011. Major reported issues included poor parent and child understanding of disease and medications. Fears, misinformed beliefs and lack of self-management skills were apparent. Child self-image, resistance to medication use and lack of responsibility in medication taking were themes that emerged from child interviews. This is one of the first research studies exploring the viewpoint of children with asthma about their medications. Resource constraints dictate a pragmatic paternalistic approach by physicians which, in contrast to patients in westernized nations, seems to be acceptable and satisfactory to Indian patients (carers). © 2013 The Authors.

The increased asthma prevalence in westernized societies has been suggested to be related to environment exposures and lifestyle changes, particularly diet. We aimed to explore the association between dietary patterns and asthma prevalence, incidence and control in a nationally representative population. Data from 32,644 adults, 53% female, from the 4th Portuguese National Health Survey were analysed. Prevalence of asthma was 5.3%; 'current asthma', defined by asthma symptoms within previous year, 3.5%; 'current medicated asthma' defined by use of asthma medication within previous year, 3.0%; 'current severe asthma' defined by emergency visit because of asthma within previous year, 1.4%; and 'incident asthma', 0.2%. Dietary patterns (DP) were identified by latent trait models based on dietary intake. Unconditional logistic regression models were performed to analyse association between DP and asthma. Age, gender, education, family income, proxy reporting information, smoking, body mass index and physical activity level were analysed as confounders. Two of the five identified DP were associated with asthma: 'high fat, sugar and salt' DP (positively correlated with pastry, chocolate and sweet desserts, candies, salty snacks, chips, fruit juices, soft drinks and alcoholic beverages consumption at snacks) was associated with asthma prevalence (OR = 1.13, 95% CI = 1.03, 1.24) and current severe asthma (OR = 1.23, 95% CI = 1.03, 1.48), while 'fish, fruit and vegetables' DP (positively correlated with fish, vegetables and fruit intake at meals) was negatively associated with current (OR = 0.84, 95% CI = 0.73, 0.98), and current medicated asthma (OR = 0.84, 95% CI = 0.72, 0.98), after adjustment for confounders. Our results suggest a protective association between 'fish, vegetables and fruit' DP and current asthma and current medicated asthma, and a detrimental association between 'high fat, sugar and salt' DP and severe asthma prevalence, further supporting the rational for diet and lifestyle intervention studies in asthma based on whole dietary patterns and physical activity. © 2015 John Wiley & Sons Ltd.

Managing problematic severe asthma: beyond the guidelines.

Pike, Katharine C; Levy, Mark L; Moreiras, John; Fleming, Louise

2018-04-01

This review discusses issues related to managing problematic severe asthma in children and young people. A small minority of children have genuinely severe asthma symptoms which are difficult to control. Children with genuinely severe asthma need investigations and treatments beyond those described within conventional guidelines. However, the majority of children with poor symptom control despite high-intensity treatment achieve improvement in their asthma control once attention has been paid to the basics of asthma management. Basic asthma management requires optimisation of inhaler technique and treatment adherence, avoidance of environmental triggers and self-management education. It is also important that clinicians recognise risk factors that predispose patients to asthma exacerbations and potentially life-threatening attacks. These correctable issues need to be tackled in partnership with children and young people and their families. This requires a coordinated approach between professionals across healthcare settings. Establishing appropriate infrastructure for coordinated asthma care benefits not only those with problematic severe asthma, but also the wider asthma population as similar correctable issues exist for children with asthma of all severities. Investigation and management of genuine severe asthma requires specialist multidisciplinary expertise and a systematic approach to characterising patients' asthma phenotypes and delivering individualised care. While inhaled corticosteroids continue to play a leading role in asthma therapy, new treatments on the horizon might further support phenotype-specific therapy. © Article author(s) (or their employer(s) unless otherwise stated in the text of the article) 2018.

The prevalence of asthma in our society is rising and there is need for better understanding of the asthma patients' perception and treatment practice of physicians. The study was aimed at determining asthma attitudes and treatment practices among adult physicians and patients in Nigeria, with the goal of identifying barriers to optimal management. To assess asthma attitudes, treatment practices and limitations among adult physicians and patients in Nigeria, a questionnaire survey was conducted among 150 patients and 70 physicians. Majority (66.7%) of the patients reported their asthma as moderate to severe, 42.7% had emergency room visit and 32% had admission due to asthma in the previous 12 months. Physicians and patients perceptions significantly differed in the time devoted to educational issues (31.4% vs.18.7%) and its contents: individual management plan (64.3% vs.33.3%), correct inhaler technique (84.0% vs.71.0%), medication side effects (80.0% vs.60.0%) and compliance 100% of time (5.7% vs. 18.7%). Patients reported that non-compliance with medication causes increased symptoms (67.0%), exacerbations (60.0%), bronchodilator use (56.0%), urgent physician visit (52.0%) and hospitalizations /ER visits (38.7%). Asthma medication in patients caused short term (10.7%) and long term side effects (20.0%). Due to side effects, 28.0% skipped and stopped their medications. Most physicians (85.7%) and patients (56.0%) agreed on the need for new medication options. The need for new medication in patients was strongly related to asthma severity, limitation of activities, side effects, cost and lack of satisfaction with current medication. With the exception of pulmonologists, physicians did not readily prescribe ICS and their prescriptions were not in line with treatment guidelines. This study has highlighted the gaps and barriers to asthma treatment which need to be addressed to improve the quality of care in Nigeria.

Objectives This paper documents individual asthma action plan presence and quick relief medication (albuterol) availability for elementary students enrolled in five Alabama school systems. Patients and Methods Data were obtained during baseline data collection (fall 2005) of a school-based supervised asthma medication trial. All students attended 1 of 36 participating elementary schools across five school systems in Jefferson County, Alabama. In addition, they had to have physician-diagnosed asthma requiring daily controller medication. Each school system had its own superintendent and elected school board. Asthma action plan presence and albuterol availability was confirmed by study personnel. Asthma action plans had to contain daily and acute asthma management instructions. Predictors of asthma action plan presence and albuterol availability were also investigated. Associations between albuterol availability and self-reported characteristics including health care utilization prior to study enrollment and outcomes during the study baseline period were also investigated. Results Enrolled students had a mean (SD) age of 11.0 (2.1) years, 91% were African American, and 79% had moderate persistent asthma. No student had a complete asthma action plan on file and only 14% had albuterol physically available at school. Albuterol availability was not predicted by gender, race, insurance status, second-hand smoke exposure, need for pre-exercise albuterol, asthma severity, or self-reported health care utilization prior to study enrollment. Albuterol availability did not predict school absences, red/yellow peak flow recordings, or medication adherence during the study's baseline period. Conclusion Despite policies permitting students to possess albuterol, few elementary students across five independent school systems in Alabama actually had it readily available at school.

The aims of this study were to examine the frequency of, and the reasons for, emergency hospitalization for asthma among children. In addition, the costs of hospital treatment, preventive medication, and productivity losses of the caregivers were evaluated in a population-based setting during 1 year. Data on purchases of regular asthma medication were obtained from the Social Insurance Institution. In total, 106 (2.3/1000) children aged up to 15 years were admitted 136 times for asthma exacerbation to the Kuopio University Hospital in 1998. This represented approximately 5% of all children with asthma in the area. The trigger for the exacerbation was respiratory infection in 63% of the episodes, allergen exposure in 24%, and unknown in 13%. The age-adjusted risk for admittance was 5.3% in children on inhaled steroids, 5.8% in those on cromones, and 7.9% in those with no regular medication for asthma. The mean direct cost for an admission was $1,209 (median $908; range $454-6,812) and the indirect cost was $358 ($316; $253-1,139). The cost of regular medication for asthma was, on average, $272 per admitted child on maintenance. The annual total cost as a result of asthma rose eight-fold if a child on regular medication was admitted for asthma.

Zambia is currently experiencing an epidemiological transition, from communicable to non-communicable diseases. The annual rate of physician-diagnosed asthma is estimated at 3 %. However, the general public's knowledge of asthma symptoms and signs, and their perception of asthma remain unknown. A survey was conducted aiming to determine knowledge and perceptions of asthma among Zambians. Adults and adolescents attending four clinics in the capital, Lusaka, were surveyed using a standardized questionnaire from July 2011 to March 2012. Data from 1,540 participants (mean age 30.7 years, 65% female) were collected. Most patients (74%) were living in low-cost housing. One hundred and sixteen (7.6%) participants reported either a medical diagnosis of asthma or currently taking asthma medications. The most frequent asthma symptoms reported were wheezing (88%), and waking up at night with either shortness of breath (85%), chest tightness (85%), or cough (67%). Medications used to treat asthma were mostly oral short-acting beta-agonists (SABA) (59%), inhaled SABA (30.2%) and antibiotics (29.8%). Inhaled steroids were only used by 16.4% while less than 1% were on long-acting beta-agonists (LABA). Many misconceptions were identified among the entire surveyed population with only 54.7% believing hospitalisations are not preventable, 54.7% believing asthma symptoms can be prevented with the right medications and 37% believing inhalers are addictive. Nearly 60% thought that people with asthma cannot exercise or play hard. Significantly more individuals with asthma compared to those without thought tablets are better than inhalers for the treatment of asthma (46% vs 30%). We conclude that knowledge on asthma is poor in Zambia, where there remains many misconceptions on asthma and its management.

Asthma self-management is aimed to improve the quality and effectiveness of asthma care by supporting the patients to manage their illness by themselves. The aim of the study was to evaluate the impact of pharmacist-delivered counselling on patients knowledge and beliefs about the medicines, adherence level, and asthma control. A prospective intervention study was conducted in community pharmacies. A total of 90 patients completed the study. Four questionnaires were used: (1) Beliefs about medicines questionnaire (BMQ), (2) Knowledge of asthma and asthma medicine (KAM), (3) Asthma control test (ACT), and (4) 8-item Morisky medication adherence scale questionnaire (MMAS-8). Questionnaires were completed at baseline and 3 months later. Low level of adherence and poor asthma control were determined initially. Better asthma control was significantly associated with higher adherence level, lower concerns regarding the medication use, and knowledge of triggers. Statistically significant improvement was found after 3 months in patients knowledge of asthma and its medications, their attitude towards medications (decrease in harm, overuse and concern; increase in necessity score), asthma control score (increased from 19 to 20, p < 0.05) and level of adherence (MMAS-8 score decreased from 3 to 2 p < 0.05). Better asthma control was achieved in 60% of patients. Sixteen patients (18%) were transferred from poor to well-controlled asthma, implying no need for patients' referral to the doctor and no additional cost for the health system. Improved disease control could be a result of enhanced knowledge and understanding of the disease-medication relationship, improved inhalation technique, and support on patients' adherence. Acquired knowledge and skills, as well as improved attitude, empowered patients to take a more active part in asthma management. Education in further patients' follow-up should consider topics tailored to the patients' characteristics, needs, and prior counselling schedule with issues discussed. Copyright © 2017 Elsevier Inc.

Pediatric asthma has variable underlying inflammation and symptom control. Approaches to addressing this heterogeneity, such as clustering methods to find phenotypes and predict outcomes, have been investigated. However, clustering based on the relationship between treatment and clinical outcome has not been performed, and machine learning approaches for long-term outcome prediction in pediatric asthma have not been studied in depth. Our objectives were to use our novel machine learning algorithm, predictor pursuit (PP), to discover pediatric asthma phenotypes on the basis of asthma control in response to controller medications, to predict longitudinal asthma control among children with asthma, and to identify features associated with asthma control within each discovered pediatric phenotype. We applied PP to the Childhood Asthma Management Program study data (n = 1,019) to discover phenotypes on the basis of asthma control between assigned controller therapy groups (budesonide vs. nedocromil). We confirmed PP's ability to discover phenotypes using the Asthma Clinical Research Network/Childhood Asthma Research and Education network data. We next predicted children's asthma control over time and compared PP's performance with that of traditional prediction methods. Last, we identified clinical features most correlated with asthma control in the discovered phenotypes. Four phenotypes were discovered in both datasets: allergic not obese (A + /O - ), obese not allergic (A - /O + ), allergic and obese (A + /O + ), and not allergic not obese (A - /O - ). Of the children with well-controlled asthma in the Childhood Asthma Management Program dataset, we found more nonobese children treated with budesonide than with nedocromil (P = 0.015) and more obese children treated with nedocromil than with budesonide (P = 0.008). Within the obese group, more A + /O + children's asthma was well controlled with nedocromil than with budesonide (P = 0.022) or with placebo (P = 0.011). The PP algorithm performed significantly better (P < 0.001) than traditional machine learning algorithms for both short- and long-term asthma control prediction. Asthma control and bronchodilator response were the features most predictive of short-term asthma control, regardless of type of controller medication or phenotype. Bronchodilator response and serum eosinophils were the most predictive features of asthma control, regardless of type of controller medication or phenotype. Advanced statistical machine learning approaches can be powerful tools for discovery of phenotypes based on treatment response and can aid in asthma control prediction in complex medical conditions such as asthma.

Adherence to medication is crucial for achieving treatment control in chronic obstructive lung diseases. This study refers to the "necessity-concerns framework" and examines the associations between beliefs about medicines and self-reported medication adherence in people with chronic obstructive lung disease. 402 patients (196 with asthma, 206 with COPD) participated in the study and completed a questionnaire comprising the "Beliefs about Medicines-Questionnaire" (BMQ) and the "Medication Adherence Report Scale" (MARS). Multivariable logistic regression analyses with the BMQ-subscales as explanatory and the dichotomized MARS-score as dependent variable were computed for the asthma and the COPD sample, respectively, and adjusted for potentially confounding variables. 19% of asthma patients and 34% of COPD patients were completely adherent to their prescribed medication. While specific beliefs about the necessity of medicines were positively associated with medication adherence both in patients with asthma and with COPD, general beliefs about harm and overuse of medicines by doctors were negatively associated with medication adherence only among patients with asthma. The findings of this study suggest that patients' specific beliefs about the necessity of medicines represent an important modifiable target for improving patient-doctor consultations when prescribing medicines.

The cost of asthma in Kuwait.

To evaluate the direct costs of treating asthma in Kuwait. Population figures were obtained from the 2005 census and projected to 2008. Treatment profiles were obtained from the Asthma Insights and Reality for the Gulf and Near East (AIRGNE) study. Asthma prevalence and unit cost estimates were based on results from a Delphi technique. These estimates were applied to the total Kuwaiti population aged 5 years and over to obtain the number of people diagnosed with asthma. The estimates from the Delphi exercise and the AIRGNE results were used to determine the number of asthma patients managed in government facilities. Direct drug costs were provided by the Ministry of Health. Treatment costs (Kuwaiti dinars, KD) were also calculated using the Delphi exercise and the AIRGNE data. The prevalence of asthma was estimated to be 15% of adults and 18% of children (93,923 adults; 70,158 children). Of these, 84,530 (90%) adults and 58,932 (84.0%) children were estimated to be using government healthcare facilities. Inpatient visits accounted for the largest portion of total direct costs (43%), followed by emergency room visits (29%), outpatient visits (21%) and medications (7%). The annual cost of treatment, excluding medications, was KD 29,946,776 (USD 107,076,063) for adults and KD 24,295,439 (USD 86,869,450) for children. Including medications, the total annual direct cost of asthma treatment was estimated to be over KD 58 million (USD 207 million). Asthma costs Kuwait a huge sum of money, though the estimates were conservative because only Kuwaiti nationals were included. Given the high medical expenditures associated with emergency room and inpatient visits, relative to lower medication costs, efforts should be focused on improving asthma control rather than reducing expenditure on procurement of medication.

COPD, asthma, and asthma-COPD overlap increase health care resource consumption, predominantly because of hospitalization for exacerbations and also increased visits to general practitioners (GPs) or specialists. Little information is available regarding this in the primary care setting. To describe the prevalence and number of GP and specialist visits for any cause or due to exacerbations in patients with COPD, asthma, and asthma-COPD overlap. COPD was defined as post-bronchodilator forced expiratory volume in 1 second/forced vital capacity (FEV 1 /FVC) ratio <0.70; asthma was defined as prior medical diagnosis, wheezing in the last 12 months, or wheezing plus reversibility (post-bronchodilator FEV 1 or FVC increase ≥200 mL and ≥12%); asthma-COPD overlap was defined as post-bronchodilator FEV 1 /FVC <0.70 plus prior asthma diagnosis. Health care utilization was evaluated as GP and/or specialist visits in the previous year. Among the 1,743 individuals who completed the questionnaire, 1,540 performed acceptable spirometry. COPD patients had a higher prevalence of any medical visits to any physician versus those without COPD (37.2% vs 21.8%, respectively) and exacerbations doubled the number of visits. The prevalence of any medical visits to any physician was also higher in asthma patients versus those without asthma (wheezing: 47.2% vs 22.7%; medical diagnosis: 54.6% vs 21.6%; wheezing plus reversibility: 46.2% vs 23.8%, respectively). Asthma patients with exacerbations had twice the number of visits versus those without an exacerbation. The number of visits was higher (2.8 times) in asthma-COPD overlap, asthma (1.9 times), or COPD (1.4 times) patients versus those without these respiratory diseases; the number of visits due to exacerbation was also higher (4.9 times) in asthma-COPD overlap, asthma (3.5 times), and COPD (3.8 times) patients. COPD, asthma, and asthma-COPD overlap increase the prevalence of medical visits and, therefore, health care resource utilization. Attempts to reduce health care resource use in these patients require interventions aimed at preventing exacerbations.

To explore the influence of personality traits and beliefs about medicines on adherence to treatment with asthma medication. Respondents were 35 asthmatic adults prescribed controller medication. They answered questionnaires about medication adherence, personality traits, and beliefs about medicines. In gender comparisons, the personality traits "Neuroticism" in men and "adherence to medication" were associated with lower adherent behaviour. Associations between personality traits and beliefs in the necessity of medication for controlling the illness were identified. Beliefs about the necessity of medication were positively associated with adherent behaviour in women. In the total sample, a positive "necessity-concern" differential predicted adherent behaviour. The results imply that personality and beliefs about medicines may influence how well adults with asthma adhere to treatment with asthma medication.

Hyperthyroidism complicating asthma treatment.

PubMed

Zacharisen, M C; Fink, J N

2000-01-01

Asthma is one of the most common chronic medical conditions. The usual treatment includes quick relief bronchodilator medications of the sympathomimetic class and controller medications that may include the long-acting inhaled bronchodilator salmeterol. Mild adverse cardiac and central nervous system effects are common with these medications, requiring modifications in dose or occasionally switching to a different medication. Both asthma and thyroid disease are common disorders that occasionally occur together. Hyperthyroidism may exacerbate asthma. Many symptoms of hyperthyroidism are identical to the adverse effects of the commonly used inhaled bronchodilators and include tremor, nervousness, tachycardia, wide pulse pressure, palpitations, emotional lability, agitation, nightmares, aggressive behavior, and diarrhea. In this report we describe a patient with hyperthyroidism whose symptoms initially were thought to be adverse effects of the inhaled bronchodilator medications.

Key points The 2014 UK National Review of Asthma Deaths identified potentially preventable factors in two-thirds of the medical records of cases scrutinised 45% of people who died from asthma did not call for or receive medical assistance in their final fatal attack Overall asthma management, acute and chronic, in primary and secondary care was judged to be good in less than one-fifth of those who died There was a failure by doctors and nurses to identify and act on risk factors for asthma attacks and asthma death The rationale for diagnosing asthma was not evident in a considerable number of cases, and there were inaccuracies related to the completion of medical certificates of the cause of death in over half of the cases considered for the UK National Review of Asthma Deaths Educational aims To increase awareness of some of the findings of the recent UK National Review of Asthma Deaths and previous similar studies To emphasise the need for accurate diagnosis of asthma, and of the requirements for completion of medical certificates of the cause of death To consider areas for improving asthma care and prevention of attacks and avoidable deaths Summary Despite the development and publication of evidence-based asthma guidelines nearly three decades ago, potentially preventable factors are repeatedly identified in studies of the care provided for patients who die from asthma. The UK National Review of Asthma Deaths (NRAD), a confidential enquiry, was no exception: major preventable factors were identified in two-thirds of asthma deaths. Most of these factors, such as inappropriate prescription and failure to provide patients with personal asthma action plans (PAAPs), could possibly have been prevented had asthma guidelines been implemented. NRAD involved in-depth scrutiny by clinicians of the asthma care for 276 people who were classified with asthma as the underlying cause of death in real-life. A striking finding was that a third of these patients did not actually die from asthma, and many had no recorded rationale for an asthma diagnosis. The apparent complacency with respect to asthma care, highlighted in NRAD, serves as a wake-up call for health professionals, patients and their carers to take asthma more seriously. Based on the NRAD evidence, the report made 19 recommendations for change. The author has selected six areas related to the NRAD findings for discussion and provides suggestions for change in the provision of asthma care. The six areas are: systems for provision and optimisation of asthma care, diagnosis, identifying risk, implementation of guidelines, improved patient education and self-management, and improved quality of completion of medical certificates of the cause of death.

Racial and ethnic minority youth have poorer asthma status than white youth, even after controlling for socioeconomic variables. Proper use of asthma controller medications is critical in reducing asthma mortality and morbidity. The clinical consequences of poor asthma management include increased illness complications, excessive functional morbidity, and fatal asthma attacks. There are significant limitations in research on interventions to improve asthma management in racial minority populations, particularly minority adolescents and young adults, although illness management tends to deteriorate after adolescence during emerging adulthood, the unique developmental period beyond adolescence but before adulthood. The objective of the pilot study was to test the feasibility, acceptability, and signals of efficacy of an intervention targeting adherence to controller medication in African American youth (ages 18-29) with asthma. All elements of the protocol were piloted in a National Heart, Lung, and Blood Institute (NHLBI)-funded pilot study (1R34HL107664 MacDonell). Results suggested feasibility and acceptability of the protocol as well as proof of concept. We are now ready to test the intervention in a larger randomized clinical trial. The proposed study will include 192 African American emerging adults with moderate to severe persistent asthma and low controller medication adherence recruited from clinic, emergency department, and community settings. Half of the sample will be randomized to receive a multicomponent technology-based intervention targeting adherence to daily controller medication. The multicomponent technology-based intervention consists of 2 components: (1) 2 sessions of computer-delivered motivational interviewing targeting medication adherence and (2) individualized text messaging focused on medication adherence between the sessions. Text messages will be individualized based on ecological momentary assessment. The remaining participants will complete a series of computer-delivered asthma education modules matched for length, location, and method of delivery of the intervention session. Control participants will also receive text messages between intervention sessions. Message content will be the same for all control participants and contain general facts about asthma (not tailored). It is hypothesized that youth randomized to multicomponent technology-based intervention will show improvements in medication adherence (primary outcome) and asthma control (secondary outcome) compared with comparison condition at all postintervention follow-ups (3, 6, 9, and 12 months). The proposed study was funded by NHLBI from September 1, 2016 through August 31, 2021. This project will test a brief, technology-based intervention specifically targeting adherence to asthma controller medications in an under-researched population, African American emerging adults. If successful, our multicomponent technology-based intervention aimed at improving adherence to asthma medications has the potential to improve quality of life of minority emerging adults with asthma at relatively low cost. It could eventually be integrated into clinical settings and practice to reach a large number of emerging adults with asthma.

Contesting asthma medication: patients' view of alternatives.

PubMed

Kopnina, Helen

2010-08-01

There are few studies pertaining to asthma patients' views on complementary and alternative medicine (CAM). The driving question behind the study is why some asthma patients choose noncompliance to conventional western medicine and resort to other modalities, often deemed as being 'alternative,' 'complementary,' or 'integrated.' Does the patients' emancipation movement lead to greater awareness of the benefits of alternative medicine? Does the patients' identity as asthma sufferers play a role in their decision? Case studies based on semistructured interviews were conducted between June 2009 and January 2010 with 19 asthma patients in The Netherlands who have chosen complementary and alternative medicine (CAM). Patients were contacted through online forum of Dutch asthma patients' organization Astma Fonds. We have discovered that on the whole patients in the present study were well informed about risks and benefits of both prescribed and alternative medicines. We have argued that noncompliance to medical regime by some asthma patients can be explained by the rationality of their choice based on evidence of clinical trials of commonly assigned asthma medication as well as partial and anecdotal evidence of the benefits of CAM therapies. It is the patients themselves who, by invoking the same evidence-based dominant paradigm choose to address the conflict between protagonists of 'conventional,' western medicine and other modalities. The author argues that asthma patients' noncompliance with (Western) medical regime and choice for alternative medical treatment of asthma is a matter of rational choice informed by evidence-based awareness. This evidence-based rationality particularly refers here to the patients' awareness of the rather controversial results of clinical trials of commonly used asthma medicines, particularly those containing elements of budesonide (Pulmicort), an anti-inflammatory corticosteroid, and formoterol (Oxis, Foradil), a rapid-acting and long-lasting beta(2)-agonist (bronchodilator).

Little information is available regarding medical utilization and cost in patients with overlap syndrome of chronic obstructive pulmonary disease (COPD) and asthma. The purpose of this study is to analyze medical utilization and cost in patients with overlap syndrome and to compare them to COPD patients without asthma. Using the 2009 Korean National Health Insurance (NHI) database, COPD patients were identified. Medical utilization and costs were also analyzed. Of a total of 185,147 patients identified with COPD, 101,004 patients were classified with overlap syndrome of COPD and asthma and 84,143 patients with COPD without asthma. In 2009, the percentages of emergency room visits, admissions, and intensive care unit admissions were 14.6%, 30.5%, and 0.5%, respectively, in the patients with overlap syndrome group and 5.0%, 14.1%, and 0.2%, respectively, in the COPD patients without asthma group (p < 0.05 for all comparisons). The cost of medical utilization was 790 ± 71 US dollars per person and 3,373 ± 4,628 dollars per person for outpatient and inpatient services, respectively, in the patients with overlap syndrome and 413 ± 512 and 3,010 ± 5,013, respectively, in the COPD patients without asthma (p < 0.05 for all comparisons). Multiple linear regression showed that age, sex, overlap syndrome, hospitalization in the last year, low socioeconomic status, and type of hospital use were significant factors affecting medical utilization and cost. In patients with overlap syndrome, both medical utilization and cost were higher than in COPD patients without asthma.

To compare asthma-related resource utilization, adherence and costs among adults prescribed asthma controller regimens. Medical and pharmacy claims from a US managed-care claims database were used to identify adults (18-56 years) initiating asthma controller therapy. Patients had 2 years continuous enrollment and ≥ 1 medical claims for asthma (ICD9: 493.xx) (January 2004 - March 2009). Asthma exacerbations, short-acting β-agonist (SABA) fills, adherence (MPR ≥ 0.80) and asthma-related costs were assessed for 1 year after the initial asthma controller medication claim. Separate logistic and negative binomial regression models for monotherapy and combination therapy were developed to examine the impact of controller therapy on outcomes. A total of 28 074 patients [inhaled corticosteroids (ICS) (26.3%), leukotriene modifiers (LM) (23.2%), ICS  +  long acting β-agonist (LABA) (48.5%), ICS + LM (2%)] were included. LM patients had lower odds of ≥ 6 SABA fills (OR(adj) = 0.83, 95% CI: 0.73-0.96) and lower rates of asthma exacerbations (RR(adj) = 0.82, 0.75-0.89) vs. ICS patients. Odds of ≥ 6 SABA fills were similar for ICS + LM vs. ICS + LABA (OR(adj) = 1.3, 0.96-1.76); the rate of asthma exacerbations was greater for ICS + LM compared with ICS + LABA (OR(adj) = 1.4, 1.2-1.6). The proportion adherent was greatest for LM (14.9%) and ICS + LABA (4.1%). LM patients had higher unadjusted pharmacy costs, but lower medical costs compared to ICS patients. For combination therapy, ICS + LM had higher unadjusted mean medical and pharmacy costs vs. ICS + LABA. Higher adjusted mean total costs in the post-index period were observed for LM vs. ICS patients ($837 vs. 684) and for ICS + LM vs. ICS + LABA patients ($1223 vs. 873). LM monotherapy was associated with lower medical costs but higher total costs resulting from greater treatment adherence. Conversely, higher costs for ICS + LM resulted from greater exacerbations compared to ICS + LABA despite similar adherence. Higher total costs with LM were due to drug costs. Precise utilization of the medications filled by patients could not be determined.

Asthma is a chronic inflammatory condition affecting the airways leading to spasm and swelling of the airways. The medications taken for the treatment of asthma can result in dental erosion and dentin hypersensitivity. The aims of this study were to investigate the severity of dental erosion amongst adult asthmatics according to: gender, type and duration of medication taken and to compare dental erosion and dentin hypersensitivity between asthmatics and non-asthmatics. Comparative, cross-sectional hospital based study among 40 asthmatics (M=15 & F=25) and 40 non-asthmatics (M=18 & F=22) in the age range of 18-60 year selected purposefully from Al-Shaab Teaching Hospital in Khartoum city. The Basic Erosive Wear Index was used for dental erosion assessment. Dentine hypersensitivity was determined by giving ice cold water and rated using the Visual Analogue Scale. Chi-square and Student's t-test were used for statistical analysis with P value ≤.05. There was an association between severity of dental erosion and presence of asthma (P=0.03), where asthmatics had a higher degree of erosion (moderate and severe) and non-asthmatics a lower degree. No significant association was found between dental erosion and gender, type and duration of medication among asthmatics group. A statistically significant difference was revealed in the degree of dentin hypersensitivity (P=0.00) among asthmatics (35.13%) and non-asthmatics (14.13%). Asthmatic patients had a higher degree of dental erosion and dentin hypersensitivity compared to non-asthmatics. Among asthmatic patients there was no association between severity of dental erosion and gender, type and duration medication was taken for.

Background Asthma severity, control, type of medical regimen provided and compliance with it are not well understood in minority patients at the transition stage from childhood to adolescence. Objective Identify factors in clinical practice and patient behavior associated with negative outcomes for children at this developmentally significant period. Methods Parents of 1292 children with asthma among 6827 pre-teens in 19 middle schools in predominantly African American (94%), low income neighborhoods in Detroit, Michigan were enrolled. Data collected through self administered survey and telephone interviews were useable for 936 parents. Study queries related to demographics, asthma symptoms, and medication use. Mixed effects models with a random intercept for school used to determine severity and control and association of medical regimens to these. Results Sixty-seven percent children with probable asthma had received a physician's diagnosis. Being female was associated with being undiagnosed (p=0.02); 47% with no diagnosis had persistent asthma and 68% with a diagnosis and asthma medicines were not controlled. Over half with a diagnosis and no medicine were not controlled. Thirty nine percent had controller medicine; 40% were not compliant with controller use; 9% nebulized controller medicine. Compliant use of controller medicine was not associated with asthma control (p=0.001). Conclusions Lack of an asthma diagnosis was significant in these low income communities. Adolescent girls were at risk for not receiving a diagnosis. Regimens provided children at an important stage in their development were not consistent with therapies recommended for asthma control. Patient compliance with asthma regimens was low. Both clinical and patient education regarding effective asthma management is needed regarding pre teens in low income minority communities. Clinical Implications Diagnosis and medical therapy choices for low income, African American pre-adolescents may not account for the actual level of their symptoms. Asthma is likely to be uncontrolled at this significant developmental stage in this population. Girls may be at risk for diagnosis failure. PMID:20170321

The impact of prescription charges on asthma patients is uneven and unpredictable: evidence from qualitative interviews.

PubMed

Schafheutle, Ellen I

2009-12-01

To explore whether, and how, prescription charges affect asthma patients' disease management behaviour. Thirty qualitative interviews. Interviewees were aged between 21 and 59, 21 were women, 24 were paying individual prescription charges, and six had prepayment certificates (PPCs). Most had a beta2-agonist 'reliever' and a steroid 'preventer' inhaler. Prescription charges posed affordability issues for some, and for two patients cost-related reduction in 'preventer' use affected asthma control negatively. Many described various ways of keeping medication cost down. Affordability issues, negative views on paying charges, and whether interviewees viewed their asthma medication as essential, were influential factors. Steroid inhalers were viewed more commonly as being less essential and affected by cost. The episodic nature of asthma meant that predicting benefit from PPCs was difficult. This study strengthens existing evidence that medication cost is a factor in asthma patients' management decisions, with a potential cost-related impact on asthma control.

Adherence to medication is one of the critical determinants of successful management of chronic diseases including asthma and chronic obstructive pulmonary disease (COPD). Given that poor adherence with self-management medication is very common among asthma and COPD patients, interventions that improve the use of chronic disease management medications for this patient group have potential to generate positive health outcomes. In an effort to improve asthma and COPD care, the Lung Association of Saskatchewan has implemented an intervention by providing access to effective and high quality asthma and COPD education for both patients and health care professionals along with increasing access to spirometry. By evaluating the impacts of this intervention, our purpose in this paper is to examine the effectiveness of spirometry use, and asthma and COPD education in primary care setting on medication use among asthma and COPD patients. At the time of the intervention, the Lung Association of Saskatchewan has not assigned a control group. Therefore we used a propensity score matching to create a control group using administrative health databases spanning 6 years prior to the intervention. Using Saskatchewan administrative health databases, the impacts of the intervention on use of asthma and COPD medications were estimated for one to four years after the intervention using a difference in difference regression approach. The paper shows that overall medication use for the intervention group is higher than that of the control group. On average, intervention group uses more asthma and COPD drugs. Within the asthma and COPD drugs, this intervention creates a persistent effect over time in the form of higher utilization of chronic management drugs equivalent to $157 and $195 in a given year during four years after the intervention. The study suggests that effective patient education and increasing access to spirometry increases the utilization of chronic disease management drugs among asthma and COPD patients. This type of interventions with patient education focus has potential to save healthcare dollars by providing better disease management among this patient group.

Nasal polyps in patients with asthma: prevalence, impact, and management challenges

PubMed Central

Langdon, Cristobal; Mullol, Joaquim

2016-01-01

Patients with chronic rhinosinusitis with nasal polyps (CRSwNP) often have coexisting asthma under the concept of “United Airway Disease”, being the combination of both diseases, which is one of the most challenging phenotypes to treat. Although clinicians have recognized this difficult-to-treat phenotype for many years, it remained poorly characterized. There is increasing epidemiological evidence linking chronic rhinosinusitis and asthma, but a good understanding of the pathophysiology and the combined management is still lacking. Bronchial asthma is more prevalent in patients who suffer chronic rhinosinusitis, while asthmatic patients have a greater prevalence of CRSwNP than patients without asthma. The effect of CRSwNP treatment, whether medical or surgical, in asthma is today less controversial after some studies have shown improvement of asthma after medical and/or surgical treatment of CRSwNP. However, direct comparisons between surgical and medical treatments are limited. Further randomized clinical trials are, however, still needed to better understand the management when both asthma and CRSwNP occur together. This review aims at summarizing the prevalence, impact, and management challenges regarding both asthma and CRSwNP. PMID:27042129

Cesarean section without medical indication and risk of childhood asthma, and attenuation by breastfeeding.

Previous studies suggest that caesarean section (CS) may increase the risk of asthma in children, but none of them could preclude potential confounding effects of underlying medical indications for CS. We aim to assess the association between CS itself (without medical indications) and risk of childhood asthma. We conducted a hospital-based case-control study on childhood asthma with 573 cases and 812 controls in Shanghai. Unconditional logistic regression models in SAS were employed to control for potential confounders. Our study found that CS without medical indication was significantly associated with elevated asthma risk (adjusted OR = 1.58 [95% CI 1.17-2.13]). However, this risk was attenuated in children fed by exclusive breastfeeding in the first six months after birth (adjusted OR = 1.39 [95% CI 0.92-2.10]). In contrast, the risk was more prominent in children with non-exclusive breastfeeding or bottle feeding (adjusted OR = 1.91 [95% CI 1.22-2.99]). CS without medical indication was associated with an increased risk of childhood asthma. Exclusive breastfeeding in infancy may attenuate this risk.

The Role of the Primary Care Physician in Helping Adolescent and Adult Patients Improve Asthma Control

PubMed Central

Yawn, Barbara P.

2011-01-01

Many adolescents and adults with asthma continue to have poorly controlled disease, often attributable to poor adherence to asthma therapy. Failure to adhere to recommended treatment may result from a desire to avoid regular reliance on medications, inappropriate high tolerance of asthma symptoms, failure to perceive the chronic nature of asthma, and poor inhaler technique. Primary care physicians need to find opportunities and methods to address these and other issues related to poor asthma control. Few adolescents or adults with asthma currently have asthma “checkup” visits, usually seeking medical care only with an exacerbation. Therefore, nonrespiratory-related office visits represent an important opportunity to assess baseline asthma control and the factors that most commonly lead to poor control. Tools such as the Asthma Control Test, the Asthma Therapy Assessment Questionnaire, the Asthma Control Questionnaire, and the Asthma APGAR provide standardized, patient-friendly ways to capture necessary asthma information. For uncontrolled asthma, physicians can refer to the stepwise approach in the 2007 National Asthma Education and Prevention Program guidelines to adjust medication use, but they must consider step-up decisions in the context of quality of the patient's inhaler technique, adherence, and ability to recognize and avoid or eliminate triggers. For this review, a literature search of PubMed from 2000 through August 31, 2010, was performed using the following terms (or a combination of these terms): asthma, asthma control, primary care, NAEPP guidelines, assessment, uncontrolled asthma, burden, impact, assessment tools, triggers, pharmacotherapy, safety. Studies were limited to human studies published in English. Articles were also identified by a manual search of bibliographies from retrieved articles and from article archives of the author.

This study introduces a framework for analyzing and visualizing health care utilization for millions of children, with a focus on pediatric asthma, one of the major chronic respiratory conditions. The data source is the 2005 to 2012 Medicaid Analytic Extract claims for 10 Southeast states. The study population consists of Medicaid-enrolled children with persistent asthma. We translate multiyear, individual-level medical claims into sequences of discrete utilization events, which are modeled using Markov renewal processes and model-based clustering. Network analysis is used to visualize utilization profiles. The method is general, allowing the study of other chronic conditions. The study population consists of 1.5 million children with persistent asthma. All states have profiles with high probability of asthma controller medication, as large as 60.6% to 90.2% of the state study population. The probability of consecutive asthma controller prescriptions ranges between 0.75 and 0.95. All states have utilization profiles with uncontrolled asthma with 4.5% to 22.9% of the state study population. The probability for controller medication is larger than for short-term medication after a physician visit but not after an emergency department (ED) visit or hospitalization. Transitions from ED or hospitalization generally have a lower probability into physician office (between 0.11 and 0.38) than into ED or hospitalization (between 0.20 and 0.59). In most profiles, children who take asthma controller medication do so regularly. Follow-up physician office visits after an ED encounter or hospitalization are observed at a low rate across all states. Finally, all states have a proportion of children who have uncontrolled asthma, meaning they do not take controller medication while they have severe outcomes.

Asthma exacerbations and medication non-adherence are significant clinical problems during pregnancy. While asthma self-management education is effective, the number of education sessions required to maximise asthma management knowledge and inhaler technique and whether improvements persist postpartum, are unknown. This paper describes how asthma knowledge, skills, and inhaled corticosteroid (ICS) use have changed over time. Data were obtained from 3 cohorts of pregnant women with asthma recruited in Newcastle, Australia between 2004 and 2017 (N = 895). Medication use, adherence, knowledge, and inhaler technique were compared between cohorts. Changes in self-management knowledge/skills and women's perception of medication risk to the fetus were assessed in 685 women with 5 assessments during pregnancy, and 95 women who had a postpartum assessment. At study entry, 41%, 29%, and 38% of participants used ICS in the 2004, 2007, and 2013 cohorts, respectively (p = 0.017), with 40% non-adherence in each cohort. Self-management skills of pregnant women with asthma did not improve between 2004 and 2017 and possession of a written action plan remained low. Maximum improvements were reached by 3 sessions for medications knowledge and one session for inhaler technique, and were maintained postpartum. ICS adherence was maximally improved after one session, but not maintained postpartum. Perceived risk of asthma medications on the fetus was highest for corticosteroid-containing medication; and was significantly reduced following education. There was a high prevalence of non-adherence and poor self-management skills in all cohorts. More awareness of the importance of optimal asthma management during pregnancy is warranted, since no improvements were observed over the past decade.

Patient reminder systems and asthma medication adherence: a systematic review.

Tran, Nancy; Coffman, Janet M; Sumino, Kaharu; Cabana, Michael D

2014-06-01

One of the most common reasons for medication non-adherence for asthma patients is forgetfulness. Daily medication reminder system interventions in the form of text messages, automated phone calls and audiovisual reminder devices can potentially address this problem. The aim of this review was to assess the effectiveness of reminder systems on patient daily asthma medication adherence. We conducted a systematic review of the literature to identify randomized controlled trials (RCTs) which assessed the effect of reminder systems on daily asthma medication adherence. We searched all English-language articles in Pub Med (MEDLINE), CINAHL, EMBASE, PsychINFO and the Cochrane Library through May 2013. We abstracted data on the year of study publication, location, inclusion and exclusion criteria, patient characteristics, reminder system characteristics, effect on patient adherence rate and other outcomes measured. Descriptive statistics were used to summarize the characteristics and results of the studies. Five RCTs and one pragmatic RCT were included in the analysis. Median follow-up time was 16 weeks. All of the six studies suggested that the reminder system intervention was associated with greater levels of participant asthma medication adherence compared to those participants in the control group. None of the studies documented a change in asthma-related quality of life or clinical asthma outcomes. All studies in our analysis suggest that reminder systems increase patient medication adherence, but none documented improved clinical outcomes. Further studies with longer intervention durations are needed to assess effects on clinical outcomes, as well as the sustainability of effects on patient adherence.

Previous Thai surveys of asthma care have shown suboptimal management and poor control. Since then several editions of the Thailand National Asthma Guidelines have been distributed to help improve asthma control. A new survey was undertaken to see if any improvement in care had occurred. It examined patients' insights, attitudes and perceptions about their asthma and its treatment. Asthma patients (>12 years) were randomly selected and participated in face-to-face interviews. Patients answered 53 questions exploring general health, diagnosis, symptoms, exacerbations, patient burden, disease management, treatment and attitudes. The Global Initiative for Asthma guidelines were used to assess asthma control. Data were obtained from 400 asthma patients from 8,177 screened households. This showed that 36% had had exacerbations in the previous year, 17% had been hospitalized and 35% had had an unscheduled emergency visit to hospital or a doctor's office or clinic. Work or school was missed by 44% due to asthma while a similar number had had an asthma episode that made them feel their life was in danger. Only 8% had good asthma control. Patients had low expectations with respect to asthma treatment and their understanding of how to use therapies was poor. Forty-four percent of participants reported day-time symptoms and about one-third (34%) of adults and adolescents in the survey reported night-time symptoms at least once a week in the previous 4 weeks. Asthma patients in Thailand rated their average productivity when asthma was at its worst at 48%, on a scale of 0 to 100%, which equates to a 36% decline in productivity. Rescue medication during the previous four weeks had been used by 44% of asthma patients while 54% had used a controller medication. Pill controller medication is the most used form among those reporting controller medication use (67%), whereas 57% reported taking an inhaler. Oral steroids had been used in the previous 12 months by 40% of patients with the average number for 3 day or longer at 24 times, while the median was about 4 times. Asthma had a profound impact on patients' wellbeing, despite the availability of effective treatments and evidence-based management guidelines. A large proportion of asthma patients overestimate their asthma control and have inappropriate concepts about asthma treatment. Gaining better insight into patient's attitudes about self-care is critical to improve asthma management.

Asthma disproportionately affects minority groups, low income populations, and young children under 5. Head Start (HS) programs predominantly serve this high-risk population, yet staff are not trained on asthma management. The objective of this study was to assess a 5-year, multicomponent HS staff asthma education program in Baltimore City HS programs. All HS programs were offered annual staff asthma education by a medical research team that included didactic lectures and hands-on training. Attendees received continuing education credits. HS staff were anonymously surveyed on asthma knowledge and skills and asthma medication management practices in Year 1 (preimplementation) and Year 5. There was an estimated response rate of 94% for Year 1 and 82% for Year 5. Compared to staff in Year 1, Year 5 staff were significantly more likely to report they had very good knowledge and skills related to asthma [odds ratio (OR) 1.63; p < 0.05] and were engaged in asthma care activities (OR 2.02; p < 0.05). Self-reported presence of asthma action plans for all children with asthma was 82% at Year 1 and increased to 89% in Year 5 (p = 0.064). Year 5 HS staff reported higher self-assessed knowledge and skills, self-reports of asthma medication management practices, and self-reports of asthma activities compared to Year 1 staff. HS serves high-risk children with asthma, and a multicomponent program can adequately prepare staff to manage asthma in the child care setting. Our results indicate the feasibility of providing efficacious health skill education into child care provider training to reduce asthma knowledge gaps.

To identify risk factors and clinical course of asthma with fixed airflow limitation. A retrospective case-control study of asthma patients was conducted over a 15-month period. Asthma with fixed airflow limitation patients were defined as chronic asthmatics who had both post-bronchodilator (BD) and on-treatment ratio of forced expiratory in first second (FEV1)/forced vital capacity (FVC) persistently less than 0.7, whereas usual chronic asthma patients had post-BD and/or on-treatment ratio of FEV1/FVC more than 0.7. Serial asthma control tests (ACT), medication used, exacerbations were assessed. The risk factors were analyzed using logistic regression. Clinical characteristics between groups were compared using Student’s t-test and Fisher’s exact test. One hundred twenty from 142 eligible subjects were enrolled. They had asthma with fixed airflow limitation (n = 40) and usual chronic asthma (n = 80). Potential risk factors of asthma with fixed airflow limitation included early disease onset (age <15 years) [(adjusted odd ratio (OR) = 3.9, 95% confidence interval (CI) 1.9-8.3)] with longer disease duration (adjusted OR = 8.4, 95% CI 4.6-15.4 for >30 years). Asthma with fixed airflow limitation patients had lower ACT scores (p<0.001), lower level of asthma control (p<0.001), required more asthma medications (p = 0.002), and higher rates of hospitalization (p = 0.001) than usual chronic asthma. The potential risk factors of asthma with fixed airflow limitation were earlier disease onset and longer disease duration. They had poorer asthma control, more medications needed, and higher rates of exacerbation than usual chronic asthma.

To identify patterns of asthma control and treatment in Australian adults with asthma. Cross-sectional web-based survey, conducted 1-27 November 2012. Adults with current asthma, at least 16 years of age, drawn randomly from a web-based panel and weighted to reflect national population proportions for people with asthma. Asthma Control Test (ACT) scores; health care utilisation; medication use. 2686 participants completed the survey (57.1% female; median age group, 40-49 years). Mean ACT score was 19.2 (95% CI, 18.9-19.3), with asthma classified as "well controlled" for 54.4% of participants, "not well controlled" for 22.7% and "very poorly controlled" for 23.0%. 60.8% reported using preventer medication (mostly combined inhaled corticosteroid/long-acting β2-agonist) during the previous year. 23.4% had made at least one urgent visit to a general practitioner concerning their asthma, 10.0% at least one emergency department visit. Urgent consultations were more common for "very poorly controlled" than "well controlled" asthma (adjusted odds ratio, urgent GP visits 5.98 [95% CI, 4.75-7.54] and emergency department visits 2.59 [95% CI, 1.91-3.53] respectively). Participants were classified according to asthma symptom control and frequency of preventer medication usage: Those with "well controlled" asthma included Group A (40.0% of participants) who used preventer medication infrequently (less than 5 days a week) or not at all, consistent with mild asthma, and Group B (14.7%), who used it at least 5 days a week. Uncontrolled asthma symptoms were reported by Group C (19.7%) despite regular preventer use, and by Group D (25.7%), who used none or little. This study provides the first data about asthma control and its relationship with treatment in a large representative Australian population. The findings highlight significant preventable asthma morbidity in Australia.

Self-reported asthma and allergies in top athletes compared to the general population - results of the German part of the GA2LEN-Olympic study 2008

2010-01-01

Background Prevalence of asthma and allergies in top athletes is high. However, most previous studies did not include a general population comparison group. We aimed to compare the prevalence of asthma, allergies and medical treatment in different groups of German top athletes to the general population. Methods Prior to the 2008 Summer Olympic Games, 291 German candidates for participation (65%) completed a questionnaire on respiratory and allergic symptoms. Results were compared to those of a general population study in Germany (n = 2425, response 68%). Furthermore, associations between types of sports and the self-reported outcomes were calculated. All models were adjusted for age, sex, level of education and smoking. Results Athletes reported significantly more doctors' diagnosed asthma (17% vs. 7%), more current use of asthma medication (10% vs. 4%) and allergic rhinitis (25% vs. 17%) compared to the general population. After adjustment, top athletes only had an increased Odds Ratio for doctor's diagnosed asthma (OR: 1.6; 95% CI 1.1-2.5). Compared to the general population, athletes in endurance sports had an increased OR for doctor's diagnosed asthma (2.4; 1.5-3.8) and current use of asthma medication (1.8; 1.0-3.4). In this group, current wheeze was increased when use of asthma medication was taken into account (1.8; 1.1-2.8). For other groups of athletes, no significantly increased ORs were observed. Conclusions Compared to the general population, an increased risk of asthma diagnosis and treatment was shown for athletes involved in endurance sports. This might be due to a better medical surveillance and treatment of these athletes. PMID:21118543

Mobile healthcare (mHealth) has the potential to revolutionise the self-management of long-term medical conditions such as asthma. A user-centred design is integral if mHealth is to be embraced by patients and healthcare professionals.The aim of this study was to determine the perspectives of individuals with asthma and healthcare professionals on the use of mHealth for asthma self-management.We used a sequential exploratory mixed methods design; focus groups informed the development of questionnaires, which were disseminated to individuals with asthma and healthcare professionals.Focus group participants (18 asthma patients and five healthcare professionals) identified 12 potential uses of mHealth. Questionnaire results showed that individuals with asthma (n=186) most frequently requested an mHealth system to monitor asthma over time (72%) and to collect data to present to healthcare teams (70%). In contrast, healthcare professionals (n=63) most frequently selected a system alerting patients to deteriorating asthma control (86%) and advising them when to seek medical attention (87%). Individuals with asthma were less likely than healthcare professionals (p<0.001) to believe that assessing medication adherence and inhaler technique could improve asthma control.Our data provide strong support for mHealth for asthma self-management, but highlight fundamental differences between the perspectives of patients and healthcare professionals.

Barriers to medication adherence in asthma: the importance of culture and context.

PubMed

McQuaid, Elizabeth L

2018-03-23

Significant disparities exist in asthma outcomes. Racial and ethnic minorities have lower controller medication adherence, which may contribute to differences in asthma morbidity between minority and non-minority groups. The objective of this review is to identify individual, patient-provider communication, and systems issues that contribute to this pattern of medication underuse and to discuss potential strategies for intervention. Data were gathered from numerous sources, including reports of pharmacy and medical records, observational studies, and trials. Studies analyzed factors contributing to patterns of asthma medication adherence that differ by race and ethnicity. There is clear evidence of underuse of asthma controller medications among racial and ethnic minorities in prescription receipt, prescription initiation, and medication use once obtained. Individual factors such as medication beliefs and depressive symptoms play a role. Provider communication is also relevant, including limited discussion of Complementary and Alternative Medicine (CAM) use, difficulties communicating with patients and caregivers with limited English proficiency (LEP), and implicit biases regarding cultural differences. Systems issues (e.g., insurance status, cost) and social context factors (e.g. exposure to violence) also present challenges. Culturally-informed strategies that capitalize on patient strengths and training providers in culturally-informed communication strategies hold promise as intervention approaches. Disparities in controller medication use are pervasive. Identifying the sources of these disparities is a critical step toward generating intervention approaches to enhance disease management among the groups that bear the greatest asthma burden.

Caregiver goals, an integral part of a partnership for asthma management, have been found to influence asthma outcomes in children. These goals are likely to change during the transitional period of adolescence to address the needs of teenagers as they mature and assume greater responsibilities for their own care. Little is known about the goals, beliefs, and concerns of caregivers as they begin to shift responsibilities for asthma management to teens. This study sought to identify the asthma management goals, beliefs, and concerns of primarily African American caregivers of urban middle and older adolescents. Fourteen caregivers of urban African American adolescents aged 14-18 years with asthma participated in a focus group session. An iterative process was used to identify themes from the session related to asthma management goals, concerns, and beliefs of caregivers. Caregivers identified goals that related to supporting their teens' progress toward independent asthma self-management. They described significant concerns related to the teens' ability to implement asthma self-management, especially in school settings. Caregivers also revealed beliefs that represented knowledge deficits related to asthma medications and factors that improved or worsened asthma. Most caregivers identified grave concerns about school policies regarding asthma medication administration and the lack of knowledge and support provided by teachers and staff for their teen. Caregivers are an invaluable resource in the care of adolescents with asthma. An opportunity exists to improve caregiver understanding of asthma medications and to provide support through improvements in asthma care for adolescents in school-based settings.

Background Asthma accounts for considerable burden on health care, but in most cases, asthma can be controlled. Quality-of-care indicators would aid in monitoring asthma management. We describe the quality of asthma care using a set of proposed quality indicators. Methods We performed a retrospective cross-sectional study using health databases in Saskatchewan, a Canadian province with a population of about 1 million people. We assessed 6 quality-of-care indicators among people with asthma: admission to hospital because of asthma; poor asthma control (high use of short-acting β-agonists, admission to hospital because of asthma or death due to asthma); no inhaled corticosteroid use among patients with poor control; at least moderate inhaled corticosteroid use among patients with poor control; high inhaled corticosteroid use and use of another preventer medication among patients with poor control; and any main preventer use among patients with poor control. We calculated crude and adjusted rates with 95% confidence intervals. We tested for differences using the χ2 test for proportions and generalized linear modelling techniques. Results In 2002/03, there were 24 616 people aged 5–54 years with asthma in Saskatchewan, representing a prevalence of 3.8%. Poor symptom control was observed in 18% of patients with asthma. Among those with poor control, 37% were not dispensed any inhaled corticosteroids, and 40% received potentially inadequate doses. Among those with poor control who were dispensed high doses of inhaled corticosteroids, 26% also used another preventer medication. Hospital admissions because of asthma were highest among those aged 6–9 years and females aged 20–44 years. Males and those in adult age groups (predominantly 20–44 years) had worse quality of care for 4 indicators examined. Interpretation Suboptimal asthma management would be improved through increased use of inhaled corticosteroids and preventer medications, and reduced reliance on short-acting β-agonist medications as recommended by consensus guidelines.

Children with asthma require multiple medications, and cost may be a barrier to care. The purpose of this study was to determine how often physicians ask about cost when prescribing new asthma medication and to identify factors influencing queries. We surveyed pediatricians and family physicians and asked whether they asked about cost when prescribing new asthma medication and if cost was a barrier to prescribing. One third of physicians (35%) reported that concern for cost to the family was a barrier to prescribing. Half reported not asking their patients about drug costs. Pediatricians were less likely to ask about cost (odds ratio [OR] = 0.43; 95% confidence interval [CI] = 0.20–0.92) when compared with family physicians. For every 10% increase in the number of privately insured patients, a physician was less likely to ask about cost (OR = 0.83; 95% CI = 0.74–0.94). Communication about medication costs should be included in childhood asthma management. PMID:19164133

The Dutch College of General Practitioners (NHG) guidelines 'Adult asthma' and 'COPD' have been revised. New spirometry reference values from the Global Lung Function Initiative are recommended. Airway obstruction is defined as a FEV1/FVC ratio below the 5th percentile for the reference population. Spirometry for diagnosis takes place without use of patients' inhaled medication and consists of measurements before and after standardized bronchodilation. In monitoring spirometry, patients continue using inhaled medication and standardized bronchodilation is not indicated. The goal of asthma management is optimal asthma control, tailored to individual goals. The most important non-drug intervention in asthma and COPD is to recommend stopping smoking. The goal of COPD management is to limit symptoms, improve exercise capacity and quality of life, and reduce the burden of disease. Inhaled corticosteroids are usually not indicated in COPD treatment. Patients with comorbid asthma and COPD are treated with non-drug interventions according to the COPD guideline and with medication according to the asthma guideline.

In this year's Advances in Asthma review, we discuss viral infections in asthmatic patients and potential therapeutic agents, the microbiome, novel genetic associations with asthma, air quality and climate effects on asthma, exposures during development and long-term sequelae of childhood asthma, patient-centered outcomes research, and precision medicine. In addition, we discuss application of biomarkers to precision medicine and new information on asthma medications. New evidence indicates that rhinovirus-triggered asthma exacerbations become more severe as the degree of sensitization to dust mite and mouse increase. The 2 biggest drivers of asthma severity are an allergy pathway starting with allergic sensitization and an environmental tobacco smoke pathway. In addition, allergic sensitization and blood eosinophils can be used to select medications for management of early asthma in young children. These current findings, among others covered in this review, represent significant steps toward addressing rapidly advancing areas of knowledge that have implications for asthma management.

Asthma and obesity often occur together in children. It is unknown whether asthma contributes to the childhood obesity epidemic. We aimed to investigate the effects of asthma and asthma medication use on the development of childhood obesity. The primary analysis was conducted among 2,171 nonobese children who were 5-8 years of age at study enrollment in the Southern California Children's Health Study (CHS) and were followed for up to 10 years. A replication analysis was performed in an independent sample of 2,684 CHS children followed from a mean age of 9.7 to 17.8 years. Height and weight were measured annually to classify children into normal, overweight, and obese categories. Asthma status was ascertained by parent- or self-reported physician-diagnosed asthma. Cox proportional hazards models were fitted to assess associations of asthma history with obesity incidence during follow-up. We found that children with a diagnosis of asthma at cohort entry were at 51% increased risk of developing obesity during childhood and adolescence compared with children without asthma at baseline (hazard ratio, 1.51; 95% confidence interval, 1.08-2.10) after adjusting for confounders. Use of asthma rescue medications at cohort entry reduced the risk of developing obesity (hazard ratio, 0.57; 95% confidence interval, 0.33-0.96). In addition, the significant association between a history of asthma and an increased risk of developing obesity was replicated in an independent CHS sample. Children with asthma may be at higher risk of obesity. Asthma rescue medication use appeared to reduce obesity risk independent of physical activity.

To investigate the use of asthma medication and occurrence of asthma exacerbations up to 5 years before and after the onset of type 1 diabetes mellitus (T1DM) in children and adolescents. Children and adolescents younger than 19 years with at least 2 insulin prescriptions between 1999 and 2009 classified as T1DM cohort (n = 915) and a 4 times larger reference cohort (n = 3,590) with the same age and gender were identified from the Dutch PHARMO Record Linkage System. The date of first insulin dispensing was selected as the index date. The 5-year prevalence rate of asthma medication use in the T1DM cohort (23.2%) was significantly higher than the reference cohort (18.3%) after the onset of diabetes. No statistically significant difference between the two cohorts was observed in the use of specific types of asthma medication except for short acting muscarinic antagonists that were significantly more used in the T1DM cohort (5.5%) compared with the reference cohort (0.62%) after the onset of diabetes. The incidence rate of asthma medication use declined over time with a peak in the T1DM cohort the 1st year after the onset of diabetes. Furthermore, 1 year after the index date there was a peak in incidence rate of asthma exacerbations in both T1DM (7.8 per 1,000 person year) and reference (6.8 per 1,000 person year) cohorts. T1DM is associated with statistically significantly higher asthma medication use after the onset of T1DM, especially in the 1st year after the onset of diabetes.

Cheng, Judy W M; Arnold, Renée J Goldberg

Asthma affects 20 million Americans and causes a substantial loss of productivity. Medications help to increase symptom-free days and improve quality of life. Examining the cost-effectiveness of different treatments, in addition to their clinical efficacy, allows us to choose the optimal strategy in managing patients. This study reviews published pharmacoeconomic analyses of different medications used for asthma management, with a focus on medications available in the United States. English language, peer-reviewed articles, or abstracts were identified from MEDLINE and Current Contents databases (both 1966 to March 1, 2006) using the search terms asthma, pharmacoeconomics, cost-effectiveness, steroids, beta(2)-agonists, cromolyn, methylxanthines, leukotriene receptor antagonists, and omalizumab. Citations from available articles were reviewed also for additional references. Pharmacoeconomic analysis from a payer's perspective has shown that salmeterol/fluticasone is a cost-effective treatment option for moderate persistent asthma management, when compared with fluticasone with or without the addition of leukotriene modifiers. Leukotriene modifiers are less cost-effective than inhaled corticosteroids or combined inhaled steroids and long-acting beta(2)-agonists for mild or moderate persistent asthma. Anti-IgE antibody has been shown inconsistently, to be cost-effective in patients with moderate to severe allergic asthma. Although the acquisition cost of levalbuterol is higher, one study showed that it may be more cost-effective than albuterol after taking into account reduction in hospitalizations. Cost-effectiveness analyses and clinical efficacy of medications, together with other patient-specific factors, are important information to be considered when selecting treatment regimens for asthma. Future economic analysis should focus on finding better ways to evaluate productivity lost due to asthma, in addition to hospitalization.

The quality of asthma primary care may vary between countries, health care practices, and health care professionals (HCPs). Identifying and explaining such differences is critical for health services improvement. To examine the quality of asthma primary care in France and United Kingdom, and identify within-country and between-country predictors amenable to intervention. An online questionnaire to capture asthma medical care and self-management support, practice characteristics, and psychosocial determinants, was completed by 276 HCPs. Mokken Scaling analyses were used to examine item structure and consistency. Hierarchical regression analyses were used to identify predictors of the amount (number of asthma care activities HCPs delivered) and consistency (the degree to which HCPs deliver similar care) of asthma medical care and self-management support. On average, HCPs reported delivering 74,2% of guideline-recommended care. Consistency of medical care and self-management support was lower among HCPs delivering a lower amount of care (r=.58 and r=.57, p<.001). UK HCPs provided more and more consistent asthma self-management support -but not medical care- than French HCPs, which was explained by the presence of practice nurses in the UK. More training, positive social norms, and higher behavioural control explained better quality of care across all HCPs. Using carefully-developed questionnaires and advanced psychometric analyses, this study suggests that involving practice nurses, making social expectations visible, and providing more training to enhance skills and confidence in asthma care delivery could enhance the amount and consistency of asthma primary care. This needs to be corroborated in a future intervention trial. Copyright © 2018. Published by Elsevier Inc.

Medication regimens for asthma are particularly vulnerable to adherence problems because of the requirement for long-term use and periods of symptom remission experienced by patients. Pharmacists are suited to impact medication adherence given their training, skills, and frequent contact with patients. The Empowering pharmacists in asthma management through interactive SMS (EmPhAsIS) trial involves an intervention leveraging mobile health (mHealth) technology to support community pharmacy practice with the hypothesis of improved medication adherence in asthma. This study is a pragmatic pharmacy-based, cluster, randomized controlled trial with 12 months of intervention delivery and follow-up. Pharmacies (the clusters) will be randomized at a 1:1 ratio to provide intervention or usual care. The EmPhAsIS intervention consists of patient asthma education, short message service (SMS)-based monthly assessment of adherence, and follow-up of non-adherent individuals by community pharmacists. There are no inclusion or exclusion criteria for pharmacies. Patients are eligible if they: are 14 years of age or older, fill a prescription for inhaled corticosteroid (either monotherapy or in a combination inhaler with long-acting beta-agonists), have been diagnosed with asthma, possess a mobile phone with SMS capabilities, and have no communication difficulties such as inability to communicate in English, or significant impairment in vision, hearing, or speech. The primary outcome is adherence to inhaled corticosteroids ascertained by the medication possession ratio, the ratio of the days of medication supplied to days in a given time interval. This study will also evaluate secondary outcomes including: asthma control, asthma-related quality of life, asthma-related hospital admissions, and use of reliever medications during the follow-up period. A nested economic evaluation using a probabilistic decision-analytic model will be used to perform a cost-effectiveness analysis from the societal perspective of the intervention compared with usual care over a 10-year time horizon. Considering the prevalence of asthma, the extent of the non-adherence problem in this disease, and the availability of effective treatments, there is a tremendous potential to reduce the burden of asthma through improving adherence. This is the first study of an intervention based on mobile communication technology involving community pharmacists in asthma management.

This paper, developed by consensus of staff physicians of accredited asthma units for the management of severe asthma, presents information on the process and requirements for already-existing asthma units to achieve official accreditation by the Spanish Society of Pneumology and Thoracic Surgery (SEPAR). Three levels of specialized asthma care have been established based on available resources, which include specialized units for highly complex asthma, specialized asthma units, and basic asthma units. Regardless of the level of accreditation obtained, the distinction of “excellence” could be granted when more requirements in the areas of provision of care, technical and human resources, training in asthma, and teaching and research activities were met at each level. The Spanish experience in the process of accreditation of specialized asthma units, particularly for the care of patients with difficult-to-control asthma, may be applicable to other health care settings.

Previous studies showed that general practitioners have problems in diagnosing asthma accurately, resulting in both under and overdiagnosis. To support general practitioners in their diagnostic process, an asthma diagnostic consultation service was set up. We evaluated the performance of this asthma diagnostic consultation service by analysing the (dis)concordance between the general practitioners working hypotheses and the asthma diagnostic consultation service diagnoses and possible consequences this had on the patients' pharmacotherapy. In total 659 patients were included in this study. At this service the patients' medical history was taken and a physical examination and a histamine challenge test were carried out. We compared the general practitioners working hypotheses with the asthma diagnostic consultation service diagnoses and the change in medication that was incurred. In 52% (n = 340) an asthma diagnosis was excluded. The diagnosis was confirmed in 42% (n = 275). Furthermore, chronic rhinitis was diagnosed in 40% (n = 261) of the patients whereas this was noted in 25% (n = 163) by their general practitioner. The adjusted diagnosis resulted in a change of medication for more than half of all patients. In 10% (n = 63) medication was started because of a new asthma diagnosis. The 'one-stop-shop' principle was met with 53% of patients and 91% (n = 599) were referred back to their general practitioner, mostly within 6 months. Only 6% (n = 41) remained under control of the asthma diagnostic consultation service because of severe unstable asthma. In conclusion, the asthma diagnostic consultation service helped general practitioners significantly in setting accurate diagnoses for their patients with an asthma hypothesis. This may contribute to diminish the problem of over and underdiagnosis and may result in more appropriate treatment regimens. SERVICE HELPS GENERAL PRACTITIONERS MAKE ACCURATE DIAGNOSES: A consultation service can help general practitioners more accurately diagnose asthma and select the appropriate treatments for their patients. Researchers in The Netherlands, led by Frank Smeenk from Catharina Hospital in Eindhoven, describe an asthma diagnostic consultation service they created to support GPs in their diagnostic process for patients suspected of having asthma. Over a four-year period, the service received a total of 659 referrals and only confirmed the diagnosis of asthma in 275 cases. Another 20 patients had asthma overlapping with chronic obstructive pulmonary syndrome. The service also picked up other diseases, such as rhinitis, that general practitioners had missed. Overall, because of the consultation service and its revised diagnoses, more than half of all patients adjusted their medications. Most patients required only a single consultation and could then be referred back to their physicians.

To compare the abilities of teens with uncontrolled persistent asthma and their caregivers to identify inhaled medications and state correct indications for use; examine medication responsibility within dyads; and determine whether responsibility is associated with knowledge about inhaled therapies. In the baseline survey for the School-Based Asthma Care for Teens (SB-ACT) trial, we separately asked caregivers and teens to: 1) identify the teen's inhaled asthma therapies by name and from a picture chart (complete matches considered "concordant"); 2) describe indications of use for each medication; and 3) describe the allocation of responsibility for medication use within dyads. We limited analyses to dyads in which either member reported at least one rescue and one inhaled controller medication; we used McNemar and Pearson chi-square tests. A total of 136 dyads were analyzed. More caregivers than teens concordantly identified medications (63% vs 31%, P < .001). There was no difference between caregivers and teens in the ability to state correct indications for use (56% vs 54%, P = .79). More teens than caregivers endorsed "full teen responsibility" for rescue medication (65% vs 27%, P < .001) and controller medication use (50% vs 15%, P < .001). Neither concordant identification nor knowing indications for use was associated with reported medication responsibility. Medication responsibility within dyads of caregivers and teens with persistent asthma is not associated with knowledge about inhaled therapies. Targeting both members of the dyad with education and self-management strategies before responsibility transitions start may allow providers to avoid a missed opportunity to support these emerging stakeholders to adherence.

Patients with depression and other psychiatric disorders being considered for electroconvulsive therapy (ECT) may also have asthma. Since ECT requires the administration of general anaesthesia, it is assumed that extra care should be taken with asthmatic patients before and during ECT. We sought to investigate the safety of ECT in asthmatic patients. A retrospective review was conducted of the medical records of all of the patients with currently active and managed asthma who underwent ECT for severe depressive syndromes at Mayo Clinic, Rochester, Minnesota, between 1 January 1998, and 30 June 2006. Thirty-four patients with asthma who also underwent ECT were identified. Of these, 27 (79%) were women. The median age was 45 years (range 23-84 years). All 34 patients were using asthma medications daily at the time of ECT. The 34 patients underwent a total of 459 ECT sessions. Four (12%) patients experienced exacerbation of their asthma on a total of five occasions. Each exacerbation was successfully treated with standard asthma medications, and all four patients completed their courses of ECT. ECT in patients with asthma appears to be safe. Although exacerbation of asthma after ECT was rare in our series, a prospective study would be needed to determine the precise risk of pulmonary complications of ECT in asthmatic patients.

There is variation in childhood asthma between countries with typically higher prevalence in "Westernized" nations. We compared asthma, respiratory symptoms, and medication prevalence in Eastern and Central European regions and Canada. We conducted a cross-sectional survey study of children (5-15 years) from one urban centre in each of Canada, Belarus, Poland, Republic of Georgia (Adjara), Republic of Macedonia, and Ukraine. Surveys were distributed through randomly selected schools to parents (2013-2015). The prevalence of asthma differed by country from 20.6% in Canada to 1.5% in Ukraine (p < 0.001). This association remained after confounder adjustment. Except for Canada (58.7%) and Poland (42.5%), less than 10% of children with a history of wheeze had a diagnosis of asthma. Regardless of country, more than 50% of children with a diagnosis of asthma used breathing medications in the past year. Finally, except for Georgia (12.1%), all countries had a prevalence of ever wheeze above 20% (23.8% in Poland to 30.9% in Macedonia). Despite large differences in asthma prevalence, respiratory morbidity was more comparable suggesting asthma prevalence may be underestimated. Further validation of asthma diagnosis is needed. It is important to promote best diagnostic practices among first contact physicians. Copyright © 2017 Elsevier Ltd. All rights reserved.

Background: Asthma and COPD are characterized by substantial racial disparities in morbidity and mortality. We hypothesized that because African-American patients with these conditions experience greater mortality and morbidity than their white counterparts, they would use more health-care resources when no difference in health insurance exists. Methods: A retrospective, population-based cohort study was conducted using Maryland Medicaid Managed Care patient encounter data. We compared health services utilization and cost outcomes in both African-American and white patients with COPD, asthma, or coexisting COPD and asthma. Results: The study population consisted of 9,131 patients with COPD, asthma, or both conditions. Of the total population, 52% were African American (n = 4,723), and 44% were white (n = 4,021); all other races were combined into the “unknown race” category to account for the remaining 4% (n = 387). After controlling for age, gender, cohort allocation, and comorbidities, we found that African-American adults with COPD, asthma, or coexisting COPD and asthma actually used fewer medical services and accounted for lower medical costs than white adults. Conclusions: Lower health services utilization and medical costs among African-American patients with COPD and asthma may provide a possible explanation for the racial disparities in outcomes of patients with these conditions.

Long-term outcomes of asthma related to exposure to workplace dampness are not well known. The aim of this study was to evaluate the quality of life (QOL) of patients with asthma related to damp and moldy workplaces and characterize factors influencing QOL. Using a questionnaire, we followed 1267 patients previously examined for suspected occupational respiratory disease related to exposure to damp and moldy indoor environments. In addition to demographic and other background data, the questionnaire included sections on current employment status, QOL, anxiety and depression, somatization, hypochondria, and asthma medication. We compared the QOL of patients with occupational asthma (OA) with that of patients with work-exacerbated asthma (WEA) or symptoms without asthma. Impaired QOL was found among patients diagnosed with OA when they were compared with patients in corresponding environments with WEA or symptoms only. Not working and greater use of asthma medication were major determinants of worse QOL. Psychological factors did not explain the differences between the groups. OA induced by exposure to workplace moisture and molds is associated with QOL deterioration. The impairment is related to being unemployed (due to disability, retirement, job loss or other reasons) and the need for medication.

To assess whether asthma is associated with risk of appendicitis in children. We used a population-based case-control study design using a comprehensive medical record review and predetermined criteria for appendicitis and asthma. All children (age younger than 18 years of age) who resided in Olmsted County, Minnesota, and developed appendicitis between 2006 and 2012 were matched to controls (1:1) with regard to birthday, gender, registration date, and index date. Asthma status was ascertained using predetermined criteria. Active (current) asthma was defined as the presence of asthma symptoms or asthma-related events (eg, medication use, clinic visits, emergency department, or hospitalization) within 1 year before the index date. Inactive asthma was defined as subjects without these events. A conditional logistic regression model was used. Among the 309 appendicitis cases identified, when stratified according to asthma status, active asthma was associated with significantly increased risk of appendicitis compared with inactive asthma (odds ratio [OR] = 2.48; 95% confidence interval [CI], 1.22-5.03) and to no asthma (OR = 1.88; 95% CI, 1.07-3.27; overall P = .035). When controlling for potential confounders such as gender, age, and smoking status, active asthma was associated with a higher odds of developing appendicitis compared with nonasthmatic patients (adjusted OR = 1.75; 95% CI, 0.99-3.11) whereas inactive asthma was not (overall P = .049). Tobacco smoke exposure within 3 months was associated with an increased risk of appendicitis (adjusted OR = 1.66; 95% CI, 1.02-2.69). Among asthma medications, leukotriene receptor antagonists reduced the risk of appendicitis (OR = 0.18; 95% CI, 0.04-0.74). Active asthma might be an unrecognized risk factor for appendicitis in children whereas a history of inactive asthma does not pose such risk. Further investigation exploring the underlying mechanisms is warranted. Copyright © 2016 Academic Pediatric Association. Published by Elsevier Inc. All rights reserved.

Objective The current study sought to evaluate patterns of complementary and alternative medicine (CAM) use in a sample of Latino and Non-Latino white (NLW) children with asthma, to determine whether parental beliefs about conventional medications and barriers to obtaining these medications were related to CAM use, and to assess whether CAM use was associated with decreased adherence to controller medications. Methods Participants included 574 families of children with asthma from Non-Latino White, Puerto Rican, and Dominican backgrounds from RI and from Island Puerto Rico. All parents completed a brief checklist of barriers to medication use and an assessment of CAM approaches. A subsample of 259 families had controller medication use monitored objectively for approximately one month by MDILog (fluticasone propionate), TrackCap (montelukast), or dosage counter (fluticasone/salmeterol combination). Results Prevalence of CAM use was high among Latino families. Perceived barriers to obtaining medication were related to increased CAM use in Puerto Rican families from RI. Elevated medication concerns were positively associated with CAM use among NLW and Island PR families. CAM use was positively related to objective adherence within NLW families, and unrelated in other groups. Conclusions CAM use is common among Latino families with asthma. Among some families, CAM use may be initiated as a way to cope with barriers to obtaining medication or when parents have concerns about conventional medications. Families who report CAM use do not appear to be substituting CAM for conventional asthma medication. PMID:24602583

Family structure and the treatment of childhood asthma.

PubMed

Chen, Alex Y; Escarce, José J

2008-02-01

Family structure is known to influence children's behavioral, educational, and cognitive outcomes, and recent studies suggest that family structure affects children's access to health care as well. However, no study has addressed whether family structure is associated with the care children receive for particular conditions or with their physical health outcomes. To assess the effects of family structure on the treatment and outcomes of children with asthma. Our data sources were the 1996-2003 Medical Expenditure Panel Survey (MEPS) and the 2003 National Survey of Children's Health (NSCH). The study samples consisted of children 2-17 years of age with asthma who lived in single-mother or 2-parent families. We assessed the effect of number of parents and number of other children in the household on office visits for asthma and use of asthma medications using negative binomial regression, and we assessed the effect of family structure on the severity of asthma symptoms using binary and ordinal logistic regression. Our regression models adjusted for sociodemographic characteristics, parental experience in child-rearing and in caring for an asthmatic child and, when appropriate, measures of children's health status. Asthmatic children in single-mother families had fewer office visits for asthma and filled fewer prescriptions for controller medications than children with 2 parents. In addition, children living in families with 3 or more other children had fewer office visits and filled fewer prescriptions for reliever and controller medications than children living with no other children. Children from single-mother families had more health difficulties from asthma than children with 2 parents, and children living with 2 or more other children were more likely to have an asthma attack in the past 12 months than children living with no other children. For children with asthma, living with a single mother and the presence of additional children in the household are associated with less treatment for asthma and worse asthma outcomes.

To conduct a randomized controlled pilot of a multicomponent, technology-based intervention promoting adherence to controller medication in African-American emerging adults with asthma. The intervention consisted of two computer-delivered sessions based on motivational interviewing combined with text messaged reminders between sessions. Participants (N = 49) were 18-29 years old, African-American, with persistent asthma requiring controller medication. Participants had to report poor medication adherence and asthma control. Youth were randomized to receive the intervention or an attention control. Data were collected through computer-delivered self-report questionnaires at baseline, 1, and 3 months. Ecological Momentary Assessment via two-way text messaging was also used to collect "real-time" data on medication use and asthma control. The intervention was feasible and acceptable to the target population, as evidenced by high retention rates and satisfaction scores. Changes in study outcomes from pre- to postintervention favored the intervention, particularly for decrease in asthma symptoms, t (42) = 2.22, p < .05 (Cohen's d = .071). Results suggest that the intervention is feasible and effective. However, findings are preliminary and should be replicated with a larger sample and more sophisticated data analyses.

Greiling, Andrea K; Boss, Leslie P; Wheeler, Lani S

Although asthma deaths in children are rare, most asthma deaths should be preventable. No information has been identified in the professional literature addressing the occurrence of asthma deaths in schools. This investigation identified asthma deaths that occurred in US schools between 1990 and 2003 and the circumstances surrounding those deaths. Data were obtained through newspaper articles in the LexisNexis database and death certificates. Between 1990 and 2003, 38 asthma school deaths were reported. Eighteen (47%) identified deaths occurred among black children and 12 (31%) among white. Twenty-seven (72%) of the deaths occurred among teens. Of the fatal asthma attacks, 16 (42%) occurred while the children were participating in a physically active event. Twelve (31%) children died while waiting for medical assistance. Due to the nature of these data, inferences may be subject to source bias. For the identified asthma deaths, key findings include the following: (1) most deaths occurred in teens and high school students; (2) frequently, the precipitating event was related in time to exercise; and (3) a delayed response or hesitancy of school staff to provide medical assistance may have contributed to some of the deaths. Although few school-related asthma deaths are reported each year, the true number is unknown. Key factors in managing the disease and preventing asthma deaths and exacerbations in schools include identification of students with diagnosed asthma, communication with parents and health care providers, removal of triggers in the immediate school environment, and maximizing access to needed medications.

Background Asthma is the most common chronic childhood disease and has significant impact on morbidity and mortality in children. Proper adherence to asthma medication has been shown to reduce morbidity among those with asthma; however, adherence to medications is known to be low, especially among low-income urban populations. We conducted a randomized clinical trial to examine the effectiveness of an intervention designed to increase adherence to asthma medication among children with asthma that required daily collection of data. Purpose and Methods A specifically designed web-based data collection system, the Asthma Agents System, was used to collect daily data from participant children at school. These data were utilized to examine the intervention’s effectiveness in reducing the frequency of asthma exacerbations. This study examines the Asthma Agents System’s effect on the frequency of missing data. Data collection methods are discussed in detail, as well as the processes for retrieving missing data. Results For the 290 children randomized, 97% of the daily data expected were available. Of the outcome data retrieved via the Asthma Agents System, 5% of those expected were missing during the period examined. Limitations Challenges encountered in this study include issues regarding the use of technology in urban school settings, transfer of data between study sites, and availability of data during school breaks. Conclusions Use of the Asthma Agents System resulted in lower rates of missing data than rates reported elsewhere in the literature. PMID:18283077

Childhood asthma surveillance using administrative data: consistency between medical billing and hospital discharge diagnoses.

Labrèche, France; Kosatsky, Tom; Przybysz, Raymond

2008-01-01

The absence of ongoing surveillance for childhood asthma in Montreal, Quebec, prompted the present investigation to assess the validity and practicality of administrative databases as a foundation for surveillance. To explore the consistency between cases of asthma identified through physician billings compared with hospital discharge summaries. Rates of service use for asthma in 1998 among Montreal children aged one, four and eight years were estimated. Correspondence between the two databases (physician billing claims versus medical billing claims) were explored during three different time periods: the first day of hospitalization, during the entire hospital stay, and during the hospital stay plus a one-day margin before admission and after discharge ('hospital stay +/- 1 day'). During 1998, 7.6% of Montreal children consulted a physician for asthma at least once and 0.6% were hospitalized with a principal diagnosis of asthma. There were no contemporaneous physician billings for asthma 'in hospital' during hospital stay +/- 1 day for 22% of hospitalizations in which asthma was the primary diagnosis recorded at discharge. Conversely, among children with a physician billing for asthma 'in hospital', 66% were found to have a contemporaneous in-hospital record of a stay for 'asthma'. Both databases of hospital and medical billing claims are useful for estimating rates of hospitalization for asthma in children. The potential for diagnostic imprecision is of concern, especially if capturing the exact number of uses is more important than establishing patterns of use.

Children's, parents' and health professionals' views on the management of childhood asthma: a qualitative study.

The management of childhood asthma is often sub-optimal. Parents and other caregivers are primarily responsible for disease management and this responsibility includes communication with health professionals. The aim of this multi-perspective qualitative study was to explore the views of children, parents and health professionals to gain insight into the approach to clinical care in the management of childhood asthma. Interviews were held with nine parent-child (6-8 years) dyads, and 13 health professionals working in primary and secondary care. Interviews were transcribed verbatim and analysed thematically. Three key themes emerged that were common to all data sets; (1) Child and parent awareness of symptoms; (2) Management and child wellbeing; and (3) Professional communication education and consultation with families. Although some children demonstrate good awareness of symptoms and appropriate use of medication, some parents expressed difficulty in identifying triggers and symptoms of asthma. Furthermore, parents lacked awareness regarding appropriate use of medication for preventing and managing symptoms of asthma. Health professionals believed that communication and education was lacking. Data from all participants suggested that consultations could be enhanced with greater emphasis on children's and parents' perceptions of asthma in the development of asthma management plans. GUIDING FAMILIES THROUGH DISEASE MANAGEMENT: Both parents' and children's perceptions and understanding of childhood asthma should be considered when developing asthma management plans. The management of asthma is challenging and can result in poor disease outcomes if care is not taken. An individual's perception of their (or their child's) asthma can also affect the efficacy of treatment. Aidan Searle at the Bristol Biomedical Research Centre, UK, and co-workers, interviewed nine parent-child groups and thirteen health professionals to determine their perceptions of childhood asthma management in primary care. While some children had a strong awareness of symptoms and appropriate medication use, some parents found it difficult to identify asthma triggers and symptoms. Parents also displayed a lack of understanding of management through medication. Health professionals focused on the need for clearer information for families when guiding management of childhood asthma.

The CASE survey: Patient and physician perceptions regarding asthma medication use and associated oropharyngeal symptoms

PubMed Central

FitzGerald, J Mark; Chan, Charles KN; Holroyde, Martin C; Boulet, Louis-Philippe

BACKGROUND: Oropharyngeal (OP) symptoms are common in asthma patients using inhaled corticosteroids (ICSs) alone and in combination with a long-acting beta2-agonist (LABA). Patterns of medication use, level of asthma control and association with OP symptoms are not often reported in a nonstudy setting. OBJECTIVES: To determine the prevalence of OP symptoms among adult asthma patients using ICSs alone and an ICS plus a LABA; to investigate the relationships between medication use, asthma control and OP symptoms; and to assess family physicians’ (FPs’) perceptions of the prevalence and management of OP symptoms. METHODS: A random telephone survey of 1003 asthma patients and 250 FPs treating asthma patients was conducted from February to March 2005 across Canada. RESULTS: Twenty-four per cent of patients experienced OP symptoms; 67% of them spoke to their FPs about the OP symptoms. Thirty-one per cent of patients who experienced OP symptoms stopped or reduced their dose of medication. OP symptoms were reported by 25% of patients using ICSs and 22% using an ICS plus a LABA. The incidence of OP symptoms was not affected by the choice of inhalation device (metered-dose inhaler versus dry powder inhaler) or the use of a spacer. Fifty-eight per cent of patients had uncontrolled asthma; patients achieving a lower level of general education were more likely to have poor control. Patients with uncontrolled asthma were more likely than those with controlled asthma to report OP symptoms (28% versus 18%, respectively; P<0.05). Eighty-nine per cent of FPs had patients who had reported OP symptoms to them. FPs estimated that 15% of their patients experienced OP symptoms and that compliance to treatment worsened in approximately 20% of them. CONCLUSIONS: The prevalence of OP symptoms in asthma patients using ICSs and an ICS plus a LABA is significant. OP symptoms were found to be associated with a reduced patient education level, with a likelihood of reducing or stopping medication, and with a less well-controlled asthma patient. While FPs recognized that a significant proportion of their asthma patients experience OP symptoms and that OP symptoms may affect compliance, they underestimated the prevalence of this problem.

To identify urban adults' perceptions of facilitators and barriers to asthma control, including the role of self-care, medications, environmental trigger remediation, and primary care. Semi-structured open-ended qualitative interviews were conducted. Audio recordings were transcribed verbatim and entered into NVivo 10.0 (QSR International Pty Ltd, Doncaster, Victoria, Australia) for coding, analysis, and integration with demographic and asthma control data. RESULTS were analyzed by the level of asthma control. A modified grounded theory approach was used in the analysis. Thirty-five adults with persistent asthma (94% Black; 71% female; 71% with uncontrolled asthma) from the five West Philadelphia zip codes with the highest asthma burden participated. Generally, all participants understood the roles of inhaled corticosteroid (ICS) and short-acting β-2 agonist (SABA) therapies in asthma self-care although they attributed systemic side effects to topical ICS administration. Compared with participants with controlled asthma, uncontrolled participants reported overusing SABAs, underusing ICS, rejecting medical and trigger remediation advice, having more negative experiences with primary care providers, and preferring more unconventional strategies to prevent or manage asthma symptoms. Personal health beliefs about control can undermine adherence to medical and environmental remediation advice and likely contributes to high rates of uncontrolled asthma in this population. Clinicians need to know whether, and to what degree, these health beliefs can be modified. It is likely that new models of care, such as patient-centered shared decision-making approaches, and new partners, such as community health workers, may be required to modify these beliefs. This would be an important first step to enhance asthma control in vulnerable populations.

Targeting patients with asthma for omalizumab therapy: choosing the right patient to get the best value for money

The asthma syndrome has many manifestations, termed phenotypes, that arise by specific cellular and molecular mechanisms, termed endotypes. Understanding an individual’s asthma phenotype helps clinicians make rational therapeutic decisions while the understanding of endotypes has led to the development of specific precision medications. Allergic asthma is an example of an asthma phenotype and omalizumab, a monoclonal antibody that neutralizes serum immunoglobulin (Ig)E, is a specific targeted treatment which was developed as a result of an understanding of the endotype of allergic asthma. Omalizumab has been widely used in clinical practice in Europe for over a decade as an add-on therapy to treat patients who have severe refractory allergic asthma. Over this period, many centres have reported their experience with omalizumab as an add-on therapy in patients with severe asthma. These ‘real world’ clinical effectiveness studies have confirmed the benefits, cost-effectiveness and clinical utility of this medication. Combining the outcomes of both sources of research has yielded important insights that may benefit patients with severe asthma, clinicians who treat them, as well as the funding agencies that reimburse the cost of this medication. The purpose of this review is to describe how to identify and evaluate a patient with asthma for whom treatment with omalizumab may be of clinical and cost-effective benefit. The assessment and investigations used to confirm allergic asthma, the objective assessment of adherence to asthma therapy and the expected benefits of add-on omalizumab treatment are described.

Asthma is a common chronic illness that imposes a heavy burden on all aspects of the patient's life, including personal and health care cost expenditures. To analyze the direct cost associated to uncontrolled asthma patients, a cross-sectional study was conducted to determine costs related to patients with uncontrolled and controlled asthma. Uncontrolled patient was defined by daytime symptoms more than twice a week or nocturnal symptoms during two consecutive nights or any limitations of activities, or need for relief rescue medication more than twice a week, and an ACQ score less than 2 points. A questionnaire about direct cost stratification in health services, including emergency room visits, hospitalization, ambulatory visits, and asthma medications prescribed, was applied. Ninety asthma patients were enrolled (45 uncontrolled/45 controlled). Uncontrolled asthmatics accounted for higher health care expenditures than controlled patients, US$125.45 and US$15.58, respectively [emergency room visits (US$39.15 vs US$2.70) and hospitalization (US$86.30 vs US$12.88)], per patient over 6 months. The costs with medications in the last month for patients with mild, moderate and severe asthma were US$1.60, 9.60, and 25.00 in the uncontrolled patients, respectively, and US$6.50, 19.00 and 49.00 in the controlled patients. In view of the small proportion of uncontrolled subjects receiving regular maintenance medication (22.2%) and their lack of resources, providing free medication for uncontrolled patients might be a cost-effective strategy for the public health system.

Stepwise management of asthma.

PubMed

Khalid, Ayesha N

2015-09-01

Stepwise management of asthma remains an area of evolving research. Asthma is one of the most expensive chronic diseases in the United States; stepwise management is an important area of focus, with several recent guidelines recommending management. This is a review of published English language literature, focusing on management guidelines for asthma in adult and pediatric patients. Asthma is a chronic disease whose assessment of severity allows for therapeutic goals to match the impairment noted. Good evidence exists to aid risk reduction, leading to decreased emergency room visits, preventing loss of lung function in adults and lung growth in children, and optimizing pharmacotherapy with reduced side effects profile. Recent asthma management guidelines incorporate 4 components of asthma care including: monitoring of severity, patient education, controlling external triggers, and medications, including recent attention to medication adherence. Asthma is an expensive chronic disease with preventive measures leading to reduced healthcare costs. Future targeted cytokine therapy to decrease serum and blood eosinophils may become an integral part of asthma management. © 2015 ARS-AAOA, LLC.

Provision of asthma education is associated with decreased hospitalizations and emergency department visits for patients with asthma. Our objective was to describe national trends in the provision of asthma education by primary care physicians in office settings. We used the National Ambulatory Medical Care Survey, a nationally representative dataset of patient visits to office-based physicians. We identified visits to primary care physicians for patients where asthma was a reason for the visit (asthma-related visits) or who had a diagnosis of asthma, but asthma was not a specific reason for the visit (asthma-unrelated visits) and estimated the percentage of visits where asthma education was provided. Data were available for asthma-related visits from 2001-2006 and from 2005-2006 only for asthma-unrelated visits. We examined time trends in asthma education and used multivariable logistic regression to identify independent patient and system-related factors that were predictors of asthma education. The percentage of asthma-related visits where asthma education was provided declined during the study period, from 50% in 2001-2002 to 38% in 2005-2006 (p = 0.03). Asthma education was provided less frequently during asthma-unrelated visits compared to asthma-related visits (12% vs. 38%, p<0.0001). Independent predictors of providing asthma education included age < or = 18 years, receipt of a controller medication, incorporation of an allied health professional during the visit, longer visit duration and Northeast region. Asthma education is underused by primary care physicians and rates have declined from 2001-2006. Interventions designed to promote awareness and greater use of asthma education are needed.

Although airway inflammation is an intrinsic and key feature of asthma, this response varies in its intensity and translation to clinical characteristics and responsiveness to treatment. The observations that clinical heterogeneity is an important aspect of asthma and a feature that likely dictates and determines responses to treatment in severe asthma, patient responsiveness to medication is incomplete, and risks for exacerbation are increased. The development of biologics, which target selected and specific components of inflammation, has been a promising advance to achieve asthma control in patients with severe disease. This article reviews the current biologics available and under development and how their use has affected asthma and which subpopulations appear to benefit the greatest.

Introduction Asthma is a variable lung condition whereby patients experience periods of controlled and uncontrolled asthma symptoms. Patients who experience prolonged periods of uncontrolled asthma have a higher incidence of exacerbations and increased morbidity and mortality rates. The ability to determine and to predict levels of asthma control and the occurrence of exacerbations is crucial in asthma management. Therefore, we aimed to determine to what extent physiological, behavioural and environmental data, obtained by mobile healthcare (mHealth) and home-monitoring sensors, as well as patient characteristics, can be used to predict episodes of uncontrolled asthma and the onset of asthma exacerbations. Methods and analysis In an 1-year observational study, patients will be provided with mHealth and home-monitoring systems to record daily measurements for the first-month (phase I) and weekly measurements during a follow-up period of 11 months (phase II). Our study population consists of 150 patients, aged ≥18 years, with a clinician's diagnosis of asthma, currently on controller medication, with uncontrolled asthma and/or minimally one exacerbation in the past 12 months. They will be enrolled over three participating centres, including Leiden, London and Manchester. Our main outcomes are the association between physiological, behavioural and environmental data and (1) the loss of asthma control and (2) the occurrence of asthma exacerbations. Ethics This study was approved by the Medical Ethics Committee of the Leiden University Medical Center in the Netherlands and by the NHS ethics service in the UK.

The "credit card" asthma self-management plan provides the adult asthmatic patient with simple guidelines for the self-management of asthma, which are based on the self-assessment of peak expiratory flow rate recordings and symptoms. The study was a trial of the clinical efficacy of the credit card plan in a high-risk group of asthmatic patients. In this "before-and-after" trial, patients discharged from the emergency department of Wellington Hospital, after treatment for severe asthma were invited to attend a series of hospital outpatient clinics at which the credit card plan was introduced. Questionnaires were used to compare markers of asthma morbidity, requirement for emergency medical care, and medication use during the 6-month period before and after intervention with the credit card plan. Of the 30 patients with asthma who attended the first outpatient clinic, 26 (17 women and 9 men) completed the program. In these 26 participants, there was a reduction in both morbidity and requirement for acute medical services: specifically, the proportion waking with asthma more than once a week decreased from 65% to 23% (p = 0.005) and the proportion visiting the emergency department for treatment of severe asthma decreased from 58% to 15% (p = 0.004). The patients attending the clinics commented favorably on the plan, in particular on its usefulness as an educational tool for monitoring and treating their asthma. Although the interpretation of this study is limited by the lack of a randomized control group, the findings are consistent with other evidence that the credit card asthma self-management plan can be an effective and acceptable system for improving asthma care in a high-risk group of adult patients with asthma.

Both asthma and obstructive sleep apnoea cause sleep disturbance, daytime sleepiness and diminished quality of life. Continuous positive airway pressure (CPAP) is efficient in reducing symptoms related to sleep apnoea. Here we report the impact of long-term use of CPAP on asthma symptoms. A survey questionnaire was distributed to all of our obstructive sleep apnoea patients with CPAP therapy in 2013. We used the Finnish version of the Asthma Control Test™ (ACT) and a visual analogue scale (0 = no symptoms, 100 = severe asthma symptoms). Asthma was defined as self-reported physician-diagnosed disease and a special reimbursement for asthma medication by the Social Insurance Institution. We sent 2577 questionnaires and received 1586 answers (61 %). One hundred ninety-seven patients were asthmatics with a prevalence of asthma among CPAP users of 13 %. We studied 152 patients (58 females) whose CPAP therapy was initiated after starting asthma medication. Their mean (SD) age was 62 (10) years, duration of CPAP 5.7 (4.7) years and their CPAP daily use was 6.3 (2.4) h. Self-reported asthma severity decreased significantly from 48.3 (29.6) to 33.1 (27.4) (p < 0.001), and ACT score increased significantly from 15.35 (5.3) to 19.8 (4.6) (p < 0.001) without a significant change in the body mass index (BMI). The percentage of patients using rescue medication daily reduced from 36 to 8 % with CPAP (P < 0.001). We noticed a significant decrease in asthma symptoms with long-term use of CPAP in patients with both asthma and obstructive sleep apnoea.

Asthma and Pregnancy: Possible to prevent complications?- With Special reference to the impact of obesity and type of airwayinflammation

PubMed

Ali, Zarqa

2017-12-01

Background Asthma is a serious global health issue and the most prevalent chronic disorder among Danish pregnant women. Exacerbations of asthma during pregnancy have been associated with increased risk of adverse pregnancy and perinatal outcomes, and by that making asthma a potential serious medical condition during pregnancy. Monitoring of asthma every four to six weeks is recommended during pregnancy, although evidence is lacking that following this recommendation will improve pregnancy outcome and, not least, be beneficial for all pregnant women with asthma. Aim The overall aim of the present thesis was to gain more knowledge of the interaction between asthma and pregnancy. The specific research questions were to identify pregnancies with low risk of an exacerbation during pregnancy, to identify risk factors for an exacerbation during pregnancy, and to compare the adverse pregnancy and perinatal outcomes in women without asthma and women with asthma monitored closely as recommended during pregnancy. Methods In study I and II, determinants of pregnancies with low risk of an exacerbation and maternal pregnancy-related risk factors for an exacerbations were investigated in a large prospective cohort study with 1.283 women with asthma. The Management of Asthma during Pregnancy (MAP) was initiated in 2007, and all pregnant women referred to Hvidovre Hospital have since then received an invitation to participate. Women were followed-up every four weeks with assessment of asthma control and adjustment of medication if necessary. In study III, the potential differences in airway hyperresponsiveness and airway inflammation, in participants (n=50) from the MAP cohort, were investigated in a post-partum examination. In study IV, the effect of maternal asthma on obstetrical and perinatal outcomes was investigated in a large case-control study, with 938 cases i.e. women with asthma from the MAP cohort, and 2.778 controls i.e. women without asthma. Results No history of pre-pregnancy exacerbations, no prescribed controller medication, and clinically stable asthma at the first visit was determinants of pregnancies with a low risk of an asthma exacerbation during pregnancy (study I). Excessive gestational weight gain (GWG) in first trimester was associated with increased risk of an asthma exacerbation during pregnancy; furthermore, the impact of GWG was dose-dependent (Study II). In study III, women experiencing an asthma exacerbation during pregnancy had more pronounced airway hyperresponsiveness and were more often non-atopic. Finally, in study IV, the overall risk of adverse obstetrical and perinatal outcomes in women with asthma monitored closely during pregnancy was low. Conclusion Women with no history of pre-pregnancy exacerbations, no prescribed controller medication, and clinically stable asthma at the first visit have a very low risk of an exacerbation. Furthermore, excessive GWG, airway hyperresponsiveness and being non-atopic are risk factors for exacerbations of asthma during pregnancy. However, the overall risk of adverse obstetrical and perinatal outcomes in women with actively managed asthma during pregnancy is comparable to women without asthma Articles published in the Danish Medical Journal are “open access”.

Obesity is associated with an increased risk of asthma in children. Atopic sensitization is a major risk factor for asthma including severe asthma in children. It is unclear if obesity is associated with worse asthma control or severity in children and how its effects compare to atopy. We sought to examine relationships of weight status and atopy to asthma control and severity among a population of predominantly low income, minority children and adolescents with persistent asthma. A cross-sectional analysis of 832 children and adolescents, age range 5-17 years, with persistent asthma was performed. Clinical assessments included asthma questionnaires of symptoms, asthma severity score, health care utilization and medication treatment step, lung function testing, and skin prick testing as well as measures of adiposity. Data were collected between December 2010 and August 2014 from Johns Hopkins Hospital in Baltimore, MD and Children's Hospital of Boston, MA. Obesity was not associated with worse asthma control or severity in this group of predominantly low income, minority children and adolescents with persistent asthma. However, a greater degree of atopy was associated with lower lung function, higher asthma severity score, and higher medication treatment step. Atopy may be a more important risk factor for asthma severity than obesity among low-income minority children and adolescents with persistent asthma living in Northeastern cities in the United States.

To determine if the asthma medication ratio predicts subsequent emergency department (ED) visits and hospital admissions in children. Retrospective cohort with two year pairs. 2007-2009 South Carolina Medicaid recipients with persistent asthma age 2-18. Controller-to-total asthma medication ratios were calculated for each patient in 2007 and 2008. Ratios range from 0-1 (1 = ideal, 0 = no controller). 2008 and 2009 asthma related ED visits, hospitalizations, and a combined outcome of ED visit or hospitalization in the subsequent 3, 6, and 12 month time periods. 19,512 patients were included. Mean age 8.9 years, 58% male, and 55% black. The ratio significantly predicted ED visits and hospitalizations over subsequent 3, 6, and 12 month time periods. The cut-point that maximized the ability to predict visits ranged from 0.4-0.6. A cutpoint of 0.5 was used in the final models. After controlling for age, race, gender, and rurality, patients with a ratio <0.5 were significantly more likely to have a subsequent emergent healthcare visit (OR 1.5-2.0). The ratio retained its predictive ability in both year-pairs for all three outcome variables, in all three time periods, with the exception of the 2008 ratio not predicting 2009 3-month and 6-month hospitalizations. The asthma medication ratio is a significant predictor of ED visits and hospitalizations in children. Using a cutoff of <0.5 to signal at-risk patients may be an effective way for populations who would benefit from increased use of controller medications to reduce future emergent asthma visits.

A Cost-Benefit Analysis of a State-Funded Healthy Homes Program for Residents With Asthma: Findings From the New York State Healthy Neighborhoods Program.

PubMed

Gomez, Marta; Reddy, Amanda L; Dixon, Sherry L; Wilson, Jonathan; Jacobs, David E

Despite considerable evidence that the economic and other benefits of asthma home visits far exceed their cost, few health care payers reimburse or provide coverage for these services. To evaluate the cost and savings of the asthma intervention of a state-funded healthy homes program. Pre- versus postintervention comparisons of asthma outcomes for visits conducted during 2008-2012. The New York State Healthy Neighborhoods Program operates in select communities with a higher burden of housing-related illness and associated risk factors. One thousand households with 550 children and 731 adults with active asthma; 791 households with 448 children and 551 adults with asthma events in the previous year. The program provides home environmental assessments and low-cost interventions to address asthma trigger-promoting conditions and asthma self-management. Conditions are reassessed 3 to 6 months after the initial visit. Program costs and estimated benefits from changes in asthma medication use, visits to the doctor for asthma, emergency department visits, and hospitalizations over a 12-month follow-up period. For the asthma event group, the per person savings for all medical encounters and medications filled was $1083 per in-home asthma visit, and the average cost of the visit was $302, for a benefit to program cost ratio of 3.58 and net benefit of $781 per asthma visit. For the active asthma group, per person savings was $613 per asthma visit, with a benefit to program cost ratio of 2.03 and net benefit of $311. Low-intensity, home-based, environmental interventions for people with asthma decrease the cost of health care utilization. Greater reductions are realized when services are targeted toward people with more poorly controlled asthma. While low-intensity approaches may produce more modest benefits, they may also be more feasible to implement on a large scale. Health care payers, and public payers in particular, should consider expanding coverage, at least for patients with poorly controlled asthma or who may be at risk for poor asthma control, to include services that address triggers in the home environment.

Factors at multiple ecological levels, including the child, family, home, medical care, and community, impact adolescent asthma outcomes. This systematic review characterizes behavioral interventions at the child, family, home, medical system, and community level to improve asthma management among adolescents. A systematic search of PubMed, SCOPUS, OVID, PsycINFO, CINAHL, and reference review databases was conducted from January 1, 2000, through August 10, 2014. Articles were included if the title or abstract included asthma AND intervention AND (education OR self-management OR behavioral OR technology OR trigger reduction), and the mean and/or median age of participants was between 11 and 16 years. We compared populations, intervention characteristics, study designs, outcomes, settings, and intervention levels across studies to evaluate behavioral interventions to improve asthma management for adolescents. Of 1230 articles identified and reviewed, 24 articles (21 unique studies) met inclusion criteria. Promising approaches to improving adherence to daily controller medications include objective monitoring of inhaled corticosteroid adherence with allergist and/or immunologist feedback on medication-taking behavior and school nurse directly observed therapy. Efficacy at increasing asthma self-management skills was demonstrated using group interactive learning in the school setting. This systematic review is not a meta-analysis, thus limiting its quantitative assessment of studies. Publication bias may also limit our findings. Novel strategies to objectively increase controller medication adherence for adolescents include allergist and/or immunologist feedback and school nurse directly observed therapy. Schools, the most common setting across studies in this review, provide the opportunity for group interactive learning to improve asthma knowledge and self-management skills.

There are limited data regarding the comparability of medication exposure information during pregnancy from maternal report and medical records, including for rheumatoid arthritis and asthma-related medications. This study included pregnant women with rheumatoid arthritis (n = 216) and asthma (n = 172) enrolled in the MothertoBaby Pregnancy Studies (2009-2014). Women reported types and dates of medications used through semi-structured telephone interviews up to three times during pregnancy and once after delivery, and medical records were obtained. We calculated Cohen's kappa coefficients and 95% confidence intervals (CIs) and per cent agreement for agreement between report and records. For rheumatoid arthritis, prednisone was reported most frequently (53%). During pregnancy, kappa coefficients for rheumatoid arthritis medications ranged from 0.32 (95% CI 0.15, 0.50) for ibuprofen, with 84.3% agreement, to 0.90 (95% CI 0.84, 0.96) for etanercept with 95.4% agreement, and was 0.44 (95% CI 0.33, 0.55) for prednisone, with 71.3% agreement. For asthma, albuterol was reported most frequently (77.9%). During pregnancy, kappa coefficients for asthma medications ranged from 0.21 (95% CI 0.08, 0.35), with 64.5% agreement for albuterol to 0.84 (95% CI 0.71, 0.96) for budesonide/formoterol, with 96.5% agreement. Where kappas for any use during pregnancy were less than excellent (i.e. ≤0.80), medication use was more frequently captured by report than record. Agreement was higher for medications typically used continuously than sporadically. Information on medication use from medical records alone may not be adequate when studying the impact of intermittently used medications during pregnancy on perinatal outcomes. © 2017 John Wiley & Sons Ltd.

Introduction Continuous or episodic allergen exposure is a major risk factor of frequent symptoms and exacerbations for patients with allergic asthma. It has been shown that temperature-controlled laminar airflow (TLA) significantly reduced allergen exposure and airway inflammation and improved quality of life of patients with poorly controlled allergic asthma. Objective The objective was to evaluate the effects of nighttime TLA when used during real-life conditions for 12 consecutive months in addition to the patients’ regular medication. Methods This multicenter, pre- and postretrospective observational study included patients with inadequately controlled moderate-to-severe allergic asthma who received add-on treatment with TLA for 12 consecutive months. Data on medication use, asthma control, asthma symptoms, lung function, use of hospital resources, and exacerbations were collected after 4 and 12 months and compared with corresponding data collected retrospectively from medical records during the year prior to inclusion in the study. Results Data from 30 patients (mean age 28; range 8–70) completing 4 months and 27 patients completing 12 months of TLA use are presented. The mean number of exacerbations was reduced from 3.6 to 1.3 (p<0.0001), and the ratio of asthma-related emergency room visits or hospitalizations diminished from 72.4 to 23.3% (p=0.001) or from 44.8 to 20.0% (p<0.05), respectively, after 12 months of TLA use. The Asthma Control Test index increased from 14.1 to 18.5 (p<0.0001). After 4 months of TLA use, clear improvements can be shown for most variables in line with the data collected after 12 months. Conclusions The addition of TLA to the patients’ regular medication significantly reduced exacerbations, asthma symptoms, and the utilization of hospital resources. The data support that TLA may be an important new non-pharmacological approach in the management of poorly controlled allergic asthma. PMID:26557252

Medication adherence is an important determinant of disease outcomes, yet medication use on average tends to be low among patients with chronic conditions, including asthma. Although several predictors of non-adherence have been assessed, more research is needed on patients' beliefs about God and how these relate to medication use. To examine the relationship between perceptions about "God's" role in health and other locus of control factors with inhaled corticosteroid (ICS) adherence among asthma patients. Participants were from a clinical trial to improve ICS adherence and were 5-56 years old, had a diagnosis of asthma, and were receiving ICS medication. Baseline adherence was estimated from electronic prescription and pharmacy fill records. Patients were considered to be adherent if ICS use was ≥80% of prescribed. A baseline survey with the Multidimensional Health Locus of Control scale was used to assess five sources (God, doctors, other people, chance, and internal). Medication adherence was low (36%). Patients' who had a stronger belief that God determined asthma control were less likely to be adherent (odds ratio [OR] 0.82, 95% confidence interval [CI] 0.70-0.96). This relationship was stronger among African American (OR 0.68, 95% CI0.47-0.99) compared to white patients (OR 0.89, 95% CI 0.75-1.04), and among adults (OR 0.81, 95% CI 0.69-0.96) compared to children (OR 0.84, 95% CI 0.58-1.22). Patients' belief in God's control of health appears to be a factor in asthma controller use, and therefore should be considered in physician-patient discussions concerning course of treatment.

To describe the prevalence and pattern of utilization of medical services in insured of SSS with a diagnosis of asthma during 1996 and 1997. The medical claims of SSS insured whose main diagnosis was asthma (ICD-9 9 493-493.9) were selected for analysis. The prevalence and medical service utilization (medical visits, emergency and hospital admissions) were estimated. Differences in health service utilization by age group were analyzed by the Poisson model. The asthma prevalence was 14.5%, being larger in patients younger than 18 years of age and in females. 54.3% of the asthmatic patients visited medical offices and the larger proportion of users was observed in the younger group (< 18 years). However, the larger proportion of users of the emergency room was observed in the 18-44 age group, while the hospital admissions was larger in the 45-64 age group. More than half (56%) of the cost per service was attributed to hospital admissions while 31% was for pharmacy services. 65.9% of the insurers with asthma had prescriptions for short relief beta-antagonist. The prevalence of asthma in this study was high and similar to rates of the disease reported in Puerto Ricans residing in the U. S. and in other areas of the island. Similarly, the prevalence differed by age in the utilization of medical services as well as the high cost of hospital admissions. Prevalence studies using other sources as well as a standard definition of the condition may be helpful to confirm these results.

In Australia, asthma is more prevalent among Indigenous than non-Indigenous people. Awareness of asthma and compliance with management plans are poor, as is engagement with health services in general. The study explored whether offering culturally appropriate music lessons could enhance asthma awareness and engagement to improve asthma and general wellbeing. Two studies undertaken in 2007 and 2009 offered music lessons to Indigenous asthmatics in a junior school and a senior school, an Aboriginal Medical Service and a community centre. Males were taught the didgeridoo and females singing and clap sticks. Associated activities of painting and boomerang throwing were offered. At regular intervals participants were assessed for their asthma status. At completion participants reported on the benefits of the study. Excellent retention occurred in Study 1 for adolescents and junior males but was poor for junior females and adults. Contributory factors to retention were parental and school support for minors and other health factors for adults. Respiratory function improved in males and both males and females reported increased wellbeing. In Study 2 retention of all participants was excellent. In addition there was increased engagement of both participants and their families with medical services. In both studies awareness of asthma and compliance with asthma management plans increased. Social skills improved as did cultural awareness. The offering of music lessons is a culturally appropriate and enjoyable intervention to promote asthma, general health awareness and engagement with medical services.

The current study sought to evaluate patterns of complementary and alternative medicine (CAM) use in a sample of Latino and non-Latino white (NLW) children with asthma to determine whether parental beliefs about conventional medications and barriers to obtaining these medications were related to CAM use and to assess whether CAM use was associated with decreased adherence to controller medications. Participants included 574 families of children with asthma from NLW, Puerto Rican (PR), and Dominican backgrounds from Rhode Island (RI) and from Island PR. All parents completed a brief checklist of barriers to medication use and an assessment of CAM approaches. A subsample of 259 families had controller medication use monitored objectively for approximately 1 month by MDILog (fluticasone propionate), TrackCap (montelukast), or dosage counter (fluticasone/salmeterol combination). Prevalence of CAM use was high among Latino families. Perceived barriers to obtaining medication were related to increased CAM use in PR families from RI. Elevated medication concerns were positively associated with CAM use among NLW and Island PR families. CAM use was positively related to objective adherence within NLW families, and unrelated in other groups. CAM use is common among Latino families with asthma. Among some families, CAM use may be initiated as a way to cope with barriers to obtaining medication or when parents have concerns about conventional medications. Families who report CAM use do not appear to be substituting CAM for conventional asthma medication. Copyright © 2014 Academic Pediatric Association. Published by Elsevier Inc. All rights reserved.

Surveillance for incident asthma in the general population could provide timely information about asthma trends and new, emerging etiologic factors. We sought to determine the feasibility of an asthma incidence surveillance system using voluntary reporting of asthma by outpatient clinics and emergency departments (EDs). Voluntary reporting occurred from July 2002 through June 2006. We classified reported asthma based on a case definition adapted from one developed by the Council of State and Territorial Epidemiologists. We validated the case definition by having pulmonologists review data from participant interviews, medical record abstractions, and pulmonary function test (PFT) results. The positive predictive value (PPV) of meeting any of the case definition criteria for asthma was 80% to 82%. The criterion of taking at least one rescue and one controller medication had the highest PPV (97% to 100%). Only 7% of people meeting the incident case definition had a PFT documented in their medical record, limiting the usefulness of PFT results for case classification. Compared with pediatric participants, adult participants were more likely to be uninsured and to obtain asthma care at EDs. The surveillance system cost $5129 per enrolled person meeting the incident case definition and was difficult to implement in participating clinics and EDs because asthma reporting was not mandatory and informed consent was necessary. The project was useful in evaluating the case definition's validity and in describing the participants' characteristics and health-care use patterns. However, without mandatory reporting laws, reporting of incident asthma in the general population by clinicians is not likely to be a feasible method for asthma surveillance.

Objectives. This study evaluated the relationships between health insurance and welfare status and the health and medical care of children with asthma. Methods. Parents of children with asthma aged 2 to 12 years were interviewed at 6 urban clinical sites and 2 welfare offices. Results. Children whose families had applied for but were denied welfare had more asthma symptoms than did children whose families had had no contact with the welfare system. Poorer mental health in parents was associated with more asthma symptoms and higher rates of health care use in their children. Parents of uninsured and transiently insured children identified more barriers to health care than did parents whose children were insured. Conclusions. Children whose families have applied for welfare and children who are uninsured are at high risk medically and may require additional services to improve health outcomes. PMID:12197971

There is some evidence that asthmatic women are more likely to have abnormal sex hormone levels. A study was undertaken to determine whether asthma and allergy were associated with irregular menstruation in a general population, and the potential role of asthma medication for this association. A total of 8588 women (response rate 77%) participated in an 8 year follow up postal questionnaire study of participants of the ECRHS stage I in Denmark, Estonia, Iceland, Norway, and Sweden. Only non-pregnant women not taking exogenous sex hormones were included in the analyses (n = 6137). Irregular menstruation was associated with asthma (OR 1.54 (95% CI 1.11 to 2.13)), asthma symptoms (OR 1.47 (95% CI 1.16 to 1.86)), hay fever (OR 1.29 (95% CI 1.05 to 1.57)), and asthma preceded by hay fever (OR 1.95 (95% CI 1.30 to 2.96)) among women aged 26-42 years. This was also observed in women not taking asthma medication (asthma symptoms: OR 1.44 (95% CI 1.09 to 1.91); hay fever: OR 1.27 (95% CI 1.03 to 1.58); wheeze preceded by hay fever: OR 1.76 (95% CI 1.18 to 2.64)). Irregular menstruation was associated with new onset asthma in younger women (OR 1.58 (95% CI 1.03 to 2.42)) but not in women aged 42-54 years (OR 0.62 (95% CI 0.32 to 1.18)). The results were consistent across centres. Younger women with asthma and allergy were more likely to have irregular menstruation. This could not be attributed to current use of asthma medication. The association could possibly be explained by common underlying metabolic or developmental factors. The authors hypothesise that insulin resistance may play a role in asthma and allergy.

Asthma guidelines guide health practitioners to adjust treatments to the minimum level required for asthma control. As many people with asthma have an eosinophilic endotype, tailoring asthma medications based on airway eosinophilic levels (sputum eosinophils or exhaled nitric oxide, FeNO) may improve asthma outcomes. To synthesise the evidence from our updated Cochrane systematic reviews, for tailoring asthma medication based on eosinophilic inflammatory markers (sputum analysis and FeNO) for improving asthma-related outcomes in children and adults. Cochrane reviews with standardised searches up to February 2017. The Cochrane reviews included randomised controlled comparisons of tailoring asthma medications based on sputum analysis or FeNO compared with controls (primarily clinical symptoms and/or spirometry/peak flow). The 16 included studies of FeNO-based management (seven in adults) and 6 of sputum-based management (five in adults) were clinically heterogeneous. On follow-up, participants randomised to the sputum eosinophils strategy (compared with controls) were significantly less likely to have exacerbations (62 vs 82/100 participants with ≥1 exacerbation; OR 0.36, 95% CI 0.21 to 0.62). For the FeNO strategy, the respective numbers were adults OR 0.60 (95% CI 0.43 to 0.84) and children 0.58 (95% CI 0.45 to 0.75). However, there were no significant group differences for either strategy on daily inhaled corticosteroids dose (at end of study), asthma control or lung function. Adjusting treatment based on airway eosinophilic markers reduced the likelihood of asthma exacerbations but had no significant impact on asthma control or lung function. © Article author(s) (or their employer(s) unless otherwise stated in the text of the article) 2018.

Prescribed inhaled corticosteroid (ICS) doses in asthma have been studied in cross-sectional settings whereas long-term follow-up studies have not been carried out. To evaluate prescribed medication longitudinally by calculating cumulative ICS doses and dose changes in a cohort of new-onset adult asthma during 12 years and in different groups of asthma control. A total of 203 patients were followed for 12 years as part of Seinäjoki Adult Asthma Study (SAAS). All asthma-related visits and prescribed medication over the study period were collected from medical records. Total cumulative ICS dose for the 12-year follow-up period was 3.4g (±SEM 0.1) per patient. Both respiratory specialists and GPs prescribed step-ups and step-downs in ICS treatment and in total 649 dose changes were noted during the follow-up (median 3(1-5) per patient). Patients with uncontrolled asthma received higher ICS doses throughout the follow-up period, and therefore, cumulative 12-year ICS dose (3.8g ± SEM 0.2) in this group was higher than that in those with partially controlled (3.4g ± SEM 0.2) or controlled disease (2.9g ± SEM 0.2) (p = 0.0001). Patients with uncontrolled asthma were also prescribed a higher number of ICS dose changes than patients with controlled disease. Despite frequent dose changes and high ICS doses during the 12-year follow-up, the level of asthma control remained poor in patients with uncontrolled asthma. This suggests that high ICS doses may not be effective enough for management of disease in patients with uncontrolled adult-onset asthma and novel targeted treatments are required.

Objective Classroom teachers play an important role in facilitating asthma management in school but little is known about their perspectives around asthma management. We examined the perspectives of classroom teachers around barriers to school asthma management. Methods We conducted key informant interviews with 21 inner-city classroom teachers from 3rd to 5th grades in 10 Bronx, New York elementary schools. Sampling continued until thematic saturation was reached. Interviews were recorded, transcribed, and independently coded for common themes. We used thematic and content review to analyze interview data. Results Seven themes representing teachers’ perspectives on in-school asthma management emerged: (1) the problematic process of identifying students with asthma; (2) poor familiarity with the city health department’s asthma initiative and poor general knowledge of school policies on asthma management (3) lack of competency in managing an acute asthma attack in the classroom and poor recognition of symptoms of an asthma attack; (4) lack of confidence in dealing with a hypothetical asthma attack in the classroom; (5) lack of quick access to asthma medication in school; (6) limited communication between school staff; and (7) enthusiasm about learning more about asthma management. Conclusions Our results revealed several barriers contributing to suboptimal in-school asthma management: ineffective ways of identifying students with asthma, lack of teacher knowledge of guidelines on asthma management, lack of comfort in managing students’ asthma, inadequate access to asthma medication in school, and limited communication between school staff. These issues should be considered in the design of interventions to improve in-school asthma management. PMID:27031532

Asthma is related to school absenteeism and underperformance in elementary students. This pilot study assessed whether school nurse case management (CM) in children identified with asthma impacts academic performance and school absenteeism in one school. A validated questionnaire was used to identify children at risk for asthma and CM was provided to link these students to medical care and assure asthma action plans at school. In the 40 children with confirmed diagnosis who received CM, academic performance on standardized testing postintervention was similar to the 76 children who were low risk for asthma. Average days absent due to illness in the CM group were reduced from 5.8 to 3.7 days in the postintervention school year. School nurse screening, CM, and collaboration with a medical provider resulted in early identification, referral, and subsequent treatment of students at risk for asthma and may have contributed to reduced illness absences.

Little is known about the decision pathway that family physicians (FP) take in considering drug therapy for their asthma patients. This study aimed to explore the factors that influence FPs' decisions in prescribing medications for their asthma patients. A qualitative method using focus group discussions (FGD) was used to gather qualitative data based on a semi-structured topic guide from FPs of different training backgrounds and practices. 29 Singapore FPs working as private general practitioners (GP), polyclinic doctors and locums were recruited into five FGDs. The FPs' asthma drug prescription decisions were related to the FPs' medical training and acquisition of asthma-related information and updates. Uncertainty of disease diagnosis, patients' beliefs and their perceptions of the disease and treatment, as well as the FPs' concerns about drug side effects, were significant considerations for the participants. Costs related to differential subsidies in the consultation fees and drugs between public polyclinics and GP clinics in the local primary healthcare system, was a key factor in influencing the FPs' asthma drug treatment decisions. FPs' asthma drug prescribing behaviour is influenced by their medical training, disease definition, patient factors and drug costs in the context of the local primary healthcare system and policy.

Asthma Self-Management Goals, Beliefs and Behaviors of Urban African American Adolescents Prior to Transitioning to Adult Health Care.

Adolescence is a unique time of development incorporating a transition from child centered to adult centered health care. This transition period can be particularly challenging for individuals with a chronic disease such as asthma. Inadequate transition planning during adolescence may place an already vulnerable population such as African American adolescents with known health disparities in asthma prevalence, morbidity and mortality at risk for a continuation of poor health outcomes across the lifespan. Central to transition planning for these youth is the core element of developing and prioritizing goals. The purpose of this qualitative study was to explore the asthma self-management goals, beliefs and behaviors of urban African American adolescents prior to transitioning from pediatric to adult health care. A focus group composed of 13 African American adolescents with asthma ages 14-18 years from an urban population was conducted. Responses from transcripts and field notes were reviewed using an iterative process to best characterize asthma self-management goals and beliefs that emerged. Four core themes were identified: 1) medication self-management, 2) social support, 3) independence vs. interdependence, and 4) self-advocacy. Medication self-management included subthemes of rescue medications, controller medications and medication avoidance. The social support theme included three subthemes: peer support, caregiver support and healthcare provider support. Findings suggest that adolescents with asthma form both short term and long term goals. Their goals indicated a need for guided support to facilitate a successful health care transition.

Asthma is the most common chronic condition affecting children and a prominent chief complaint in pediatric emergency departments (ED). We aimed to determine parental preference between short- and long-term courses of oral corticosteroids for use in children with mild to moderate asthma presenting to our pediatric ED with acute asthma exacerbations. We surveyed parents of asthmatic children who presented to our pediatric ED from August 2011 to April 2012. Questions characterized each patient's asthma severity, assessed parental preference among systemic steroid and inhaled medication delivery options for acute asthma management, and inquired about compliance, medication costs, and intention to follow up. The majority of our parents prefer the use of 1 to 2 days of steroids to 5 days for acute asthma exacerbations in the ED. Thus, dexamethasone is an attractive alternative to prednisone/prednisolone and should be considered in the management of acute asthma exacerbations in the ED.

Background COPD, asthma, and asthma–COPD overlap increase health care resource consumption, predominantly because of hospitalization for exacerbations and also increased visits to general practitioners (GPs) or specialists. Little information is available regarding this in the primary care setting. Objectives To describe the prevalence and number of GP and specialist visits for any cause or due to exacerbations in patients with COPD, asthma, and asthma–COPD overlap. Methods COPD was defined as post-bronchodilator forced expiratory volume in 1 second/forced vital capacity (FEV1/FVC) ratio <0.70; asthma was defined as prior medical diagnosis, wheezing in the last 12 months, or wheezing plus reversibility (post-bronchodilator FEV1 or FVC increase ≥200 mL and ≥12%); asthma–COPD overlap was defined as post-bronchodilator FEV1/FVC <0.70 plus prior asthma diagnosis. Health care utilization was evaluated as GP and/or specialist visits in the previous year. Results Among the 1,743 individuals who completed the questionnaire, 1,540 performed acceptable spirometry. COPD patients had a higher prevalence of any medical visits to any physician versus those without COPD (37.2% vs 21.8%, respectively) and exacerbations doubled the number of visits. The prevalence of any medical visits to any physician was also higher in asthma patients versus those without asthma (wheezing: 47.2% vs 22.7%; medical diagnosis: 54.6% vs 21.6%; wheezing plus reversibility: 46.2% vs 23.8%, respectively). Asthma patients with exacerbations had twice the number of visits versus those without an exacerbation. The number of visits was higher (2.8 times) in asthma–COPD overlap, asthma (1.9 times), or COPD (1.4 times) patients versus those without these respiratory diseases; the number of visits due to exacerbation was also higher (4.9 times) in asthma–COPD overlap, asthma (3.5 times), and COPD (3.8 times) patients. Conclusion COPD, asthma, and asthma–COPD overlap increase the prevalence of medical visits and, therefore, health care resource utilization. Attempts to reduce health care resource use in these patients require interventions aimed at preventing exacerbations. PMID:27994446

Asthma is a common health condition for children in childcare. National recommendations for asthma in childcare exist. However, no studies have investigated the extent to which childcare centers adhere to these recommendations. We aimed to assess childcare center adherence to National Asthma Education and Prevention Program (NAEPP) recommendations for asthma care and preparedness and to identify characteristics associated with increased adherence to national asthma recommendations. We developed a standardized instrument. Each childcare center received a score of 0 through 7 based on number of recommendations met. We conducted t-tests, chi square tests and linear regression to identify childcare center factors associated with increased asthma preparedness. 36 out of 40 eligible childcare centers (90%) participated. These sites served 1570 children primarily between the ages of 2 to 5 years. On average, centers met 3.8 out of 7 (SD  =  1.3) recommendations. Staff familiarity caring for children with asthma (p < 0.001) and the center's asthma prevalence (p  =  0.01) was positively associated with the center's asthma preparedness. The 3 areas most in need of improvement related to asthma medications, asthma action plans and asthma policies. None of the managers reported being familiar with the NAEPP recommendations. There is room for improvement in the asthma care and preparedness of childcare centers. The 3 areas in which centers performed poorly (appropriate asthma medication management, use of asthma action plans, and presence of appropriate asthma policies) suggest that closer collaboration between clinicians and childcare centers may be a key to improving asthma management for young children.

Although asthma can be well controlled by appropriate medication delivered in an appropriate way at an appropriate time, there is evidence that management is often suboptimal. This results in poor asthma control, poor quality of life, and significant morbidity. The objective of this study was to describe a population recruited in community pharmacy identified by trained community pharmacists as being at risk for poor asthma outcomes and to identify factors associated with poor asthma control. It used a cross-sectional design in 96 pharmacies in metropolitan and regional New South Wales, Victoria, Queensland, and Australian Capital Territory in Australia. Community pharmacists with specialized asthma training enrolled 570 patients aged ≥18 years with doctor-diagnosed asthma who were considered at risk of poor asthma outcomes and then conducted a comprehensive asthma assessment. In this assessment, asthma control was classified using a symptom and activity tool based on self-reported frequency of symptoms during the previous month and categorized as poor, fair, or good. Asthma history was discussed, and lung function and inhaler technique were also assessed by the pharmacist. Medication use/adherence was recorded from both pharmacy records and the Brief Medication Questionnaire (BMQ). The symptom and activity tool identified that 437 (77%) recruited patients had poor asthma control. Of the 570 patients, 117 (21%) smoked, 108 (19%) had an action plan, 372 (69%) used combination of inhaled corticosteroid (ICS)/long-acting β(2)-agonist (LABA) medications, and only 17-28% (depending on device) used their inhaler device correctly. In terms of adherence, 90% had their ICS or ICS/LABA dispensed <6 times in the previous 6 months, which is inconsistent with regular use; this low adherence was confirmed from the BMQ scores. A logistic regression model showed that patients who smoked had incorrect inhaler technique or low adherence (assessed by either dispensing history or BMQ) and were more likely to have poor control. Community pharmacists were able to identify patients with asthma at risk of suboptimal control, and factors that contributed to this were elicited. This poorly controlled group that was identified may not be visible or accessible to other health-care professionals. There is an opportunity within pharmacies to target poorly controlled asthma and provide timely and tailored interventions.

The hypothesis that GER can trigger or exacerbate asthma is supported by several clinical trials that have shown amelioration in asthma symptoms and/or an improvement in pulmonary function after antireflux therapy. To investigate the prevalence of GER in patients with difficult to control asthma and to determine the effect of omeprazole on asthma symptoms, reflux symptoms, pulmonary function and on the requirement of asthma medications. Patients with difficult to control asthma were recruited into the study. All patients underwent esophageal manometry and 24 hour esophageal pH monitoring. Pulmonary function tests were done before and after treatment. The severity of asthma and reflux was assessed by a 1 week pulmonary symptom score(PSS) and reflux symptom score(RSS) respectively before and after treatment. Those who had an abnormal pH study (pH <4 in the distal esophagus for >5% of the time) underwent anti-GER treatment with lifestyle changes, and a proton pump inhibitor (omeprazole 40 mg, bid) for 3 months. Asthma medications were added or deleted based on severity of asthma. Out of 250 asthmatic patients screened, forty patients fulfilled the inclusion criteria. Twenty eight of 40 patients(70%) were diagnosed to have GERD. Of the patients 28 with GER, 8 patients(28.5%) had no reflux symptoms. On 24 hr pH metry, the percentage time pH <4.0 was 10.81 ± 4.72 and 1.11 ± 1.21; Deemester score was 37.65 ± 14.54 and 4.89 ± 6.39 (p-value is 0.0001) in GERD and non-GERD patients respectively.In GERD group, post treatment reflux symptom score(RSS) improved from 22.39 ± 14.99 to 1.04 ± 1.07, pulmonary symptom score(PSS) improved from 27.14 ± 7.49 to 13.82 ± 4.21 and night time asthma symptom score(NASS) improved from 6.71 ± 1.80 to 3.04 ± 1.23 (p-value <0.0001). After treatment, FEV1 and PEFR increased from 1.38 ± 0.57 and 4.14 ± 1.97 to 1.47 ± 0.54 and 5.56 ± 1.72, respectively (p-value 0.00114). PPI therapy improves nocturnal asthma symptoms, daytime asthma symptoms, pulmonary function and decreases requirement of asthma medications in these patients.

Objective To identify the impact of delivery device of inhaled corticosteroids and long-acting β2-agonist (ICS/LABA) on asthma medication compliance, and investigate other factors associated with compliance. Materials and methods We conducted a retrospective and multicenter study based on a review of medical registries of asthmatic patients treated with ICS/LABA combinations (n=2,213) whose medical devices were either dry powder inhalers (DPIs, such as Accuhaler®, Turbuhaler®, and NEXThaler®) or pressurized metered-dose inhalers (pMDI). Medication compliance included persistence outcomes through 18 months and medication possession ratios. Data on potential confounders of treatment compliance such as asthma exacerbations, comorbidities, demographic characteristics, and health care resource utilization were also explored. Results The probability of asthma medication compliance in case of DPIs was lower compared to pMDIs, which suggests that inhaler devices influence inhalation therapies. There were additional confounding factors that were considered as explanatory variables of compliance. A worse measure of airflow obstruction (forced expiration volume in 1 second), comorbidities and general practitioner (GP) consultations more than once per month decreased the probability of compliance. Within comorbidities, alcoholism was positively associated with compliance. Patients of 29–39, 40–50, and 51–61 age groups or suffering from more than two exacerbations during the study period were more likely to comply with their medication regime. The effects of DPIs toward compliance varied with the different DPIs. For instance, Accuhaler® had a greater negative effect on compliance compared to Turbuhaler® and Nexthaler® in cases of patients who suffered exacerbations. We found that GP consultations reduced the probability of medication compliance for patients treated with formoterol/budesonide combination. For retired patients, visiting the GP increased the probability of medication compliance. Conclusion We concluded that inhaler devices influence patients’ compliance for long-term asthma medication. The impact of Accuhaler®, Turbuhaler®, and NEXThaler® on medication compliance was negative. We also identified some confounders of medication compliance such as patient’s age, severity of asthma, comorbidities, and health care costs. PMID:26929605

In children, the prevalence's of both obesity and asthma are disconcertingly high. Asthmatic children with obesity are characterised by less asthma control and a high need for asthma medication. As the obese asthmatic child is becoming more common in the clinical setting and the disease burden of the asthma-obesity phenotype is high, there is an increasing need for effective treatment in these children. In adults, weight reduction resulted in improved lung function, better asthma control and less need for asthma medication. In children this is hardly studied. The Mikado study aims to evaluate the effectiveness of a long term multifactorial weight reduction intervention, on asthma characteristics in children with asthma and a high body weight. The Mikado study is a two-armed, randomised controlled trial. In total, 104 participants will be recruited via online questionnaires, pulmonary paediatricians, the youth department of the Municipal Health Services and cohorts of existing studies. All participants will be aged 6-16 years, will have current asthma, a Body Mass Index in the overweight or obesity range, and no serious comorbidities (such as diabetes, heart diseases). Participants in the intervention arm will receive a multifactorial intervention of 18 months consisting of sessions concerning sports, parental involvement, individual counselling and lifestyle advices including dietary advices and cognitive behavioural therapy. The control group will receive usual care. The primary outcome variables will include Forced Expiratory Volume in one second and Body Mass Index - Standard Deviation Score. Secondary outcomes will include other lung function parameters (including dynamic and static lung function parameters), asthma control, asthma-specific quality of life, use of asthma medication and markers of systemic inflammation and airway inflammation. In this randomised controlled trial we will study the potential of a multifactorial weight reduction intervention to improve asthma-related outcome measures in asthmatic children with overweight. Moreover, it will provide information about the underlying mechanisms in the relationship between asthma and a high body weight in children. These findings can contribute to optimal management programs and better clinical guidelines for children with asthma and overweight. Clinicaltrial.gov NCT00998413.

The goal of disease management (DM) is to improve health outcomes and reduce cost through decreasing health care utilization. Although some studies have shown that DM improves asthma outcomes, these interventions have not been examined in a large randomized controlled trial. To compare the effectiveness of 2 previously successful DM programs with that of traditional care. Nine hundred two individuals with asthma (429 adults; 473 children) were randomly assigned to telephonic DM, augmented DM (ADM; DM plus in-home visits by a respiratory therapist), or traditional care. Data were collected at enrollment and at 6 and 12 months. Primary outcomes were time to first asthma-related event, quality of life (QOL), and rates of asthma-related health care utilization. Secondary outcomes included rate of controller medication initiation, number of oral corticosteroid bursts, asthma symptom scores, and number of school days missed. There were no significant differences between groups in time to first asthma-related event or health care utilization. Adult participants in the ADM group had greater improvement in QOL (P = .04) and a decrease in asthma symptoms (P = .001) compared with other groups. Of children not receiving controller medications at enrollment (13%), those in the intervention groups were more likely to have controller medications initiated than the control group (P = .01). Otherwise, there were no differences in outcomes. Overall, participation in asthma DM did not result in significant differences in utilization or clinical outcomes. The only significant impact was a higher rate of controllermedication initiation in children and improvement in asthma symptoms and QOL in adults who received ADM.

Last year's "Advances in pediatric asthma in 2013: Coordinating asthma care" concluded that, "Enhanced communication systems will be necessary among parents, clinicians, health care providers and the pharmaceutical industry so that we continue the pathway of understanding the disease and developing new treatments that address the unmet needs of patients who are at risk for severe consequences of unchecked disease persistence or progression." This year's summary will focus on further advances in pediatric asthma related to prenatal and postnatal factors altering the natural history of asthma, assessment of asthma control, and new insights regarding the management of asthma in children as indicated in Journal of Allergy and Clinical Immunology publications in 2014. A major theme of this review is how new research reports can be integrated into medical communication in a population health perspective to assist clinicians in asthma management. The asthma specialist is in a unique position to convey important messages to the medical community related to factors that influence the course of asthma, methods to assess and communicate levels of control, and new targets for intervention, as well as new immunomodulators. By enhancing communication among patients, parents, primary care physicians, and specialists within provider systems, the asthma specialist can provide timely information that can help to reduce asthma morbidity and mortality.

Objective To report implementation strategies and outcomes of an evidence-based asthma counseling intervention. The Head-off Environmental Asthma in Louisiana (HEAL) intervention integrated asthma counseling (AC) capacity and addressed challenges facing children with asthma in post-disaster New Orleans. Methods The HEAL intervention enrolled 182 children (4–12 years) with moderate-to-severe persistent asthma. Recruitment occurred from schools in the Greater New Orleans area for one year. Participants received home environmental assessments and tailored asthma counseling sessions during the study period based on the National Cooperative Inner City Asthma Study and the Inner City Asthma Study. Primary (i.e. asthma symptoms) and secondary outcomes (i.e. healthcare utilization) were captured. During the study, changes were made to meet the demands of a post-hurricane and resource-poor environment which included changes to staffing, training, AC tools, and AC sessions. Results After study changes were made, the AC visit rate increased by 92.3%. Significant improvements were observed across several adherence measures (e.g., running out of medications (p=0.009), financial/insurance problems for appointments (p=0.006), worried about medication side-effects (p=0.01), felt medications did not work (p<0.001)). Additionally, an increasing number of AC visits was modestly associated with a greater reduction in symptoms (test-for-trend p=0.059). Conclusion By adapting to the needs of the study population and setting, investigators successfully implemented a counseling intervention that improved participant behaviors and clinical outcomes. The strategies for implementing the AC intervention may serve as a guide for managing asthma and other chronic conditions in resource-poor settings. PMID:27049234

It is not known which of the many asthma-specific quality of life (QoL) questionnaires best capture the lived experience of people with asthma. The objective of this study was to explore patients' views of three commonly used asthma-specific QoL questionnaires. Qualitative study using semistructured interviews. Primary and secondary care in Brighton and Hove, UK. 30 adult people with a physician-diagnosis of asthma who were asked to complete the Juniper Asthma Quality of Life Questionnaire (AQLQ-J), the Sydney Asthma Quality of Life Questionnaire (AQLQ-S) and the Living with Asthma Questionnaire (LWAQ) to elicit their views on the content validity of these. Thematic content analysis revealed a lack of congruence between the concerns of people with asthma and the questionnaire content in terms of missing (eg, allergies) and irrelevant (eg, smoky restaurants) content. The AQLQ-J was perceived as a 'narrow', 'medical' questionnaire focused on symptoms, the environment and functional ability. In contrast, the LWAQ and the AQLQ-S were perceived to be 'non-medical'. The LWAQ was described as a 'test' and as a wide-ranging, embracing and holistic questionnaire. Its strong emotional focus was irritating to some. The AQLQ-S was described as a simple, quick and easy questionnaire, although there was a perception that it was lacking in depth. Patient interviews highlighted strengths and shortcomings in the content validity of these three asthma-specific questionnaires. For patients, the AQLQ-S content seemed to be the most pertinent in its adequacy of coverage of medical, social and emotional aspects of health-related QoL in asthma.

Live attenuated influenza vaccine (LAIV) might increase the risk of wheezing in persons with asthma or children younger than 5 years with a history of recurrent wheezing. To describe the use and assess the safety of LAIV in persons with asthma in the Vaccine Safety Datalink population. We identified persons with asthma using diagnosis codes and medication records in 7 health care organizations over 3 influenza seasons (2008-2009 through 2010-2011) and determined their influenza vaccination rates. Using the self-controlled risk interval method, we calculated the incidence rate ratio of medically attended respiratory events in the 14 days after LAIV compared with 29 to 42 days after vaccination in persons 2 through 49 years old. In our population of 6.3 million, asthma prevalence was 5.9%. Of persons with asthma, approximately 50% received any influenza vaccine but less than 1% received LAIV. The safety study included 12,354 LAIV doses (75% in children; 93% in those with intermittent or mild persistent asthma). The incidence rate ratio for inpatient and emergency department visits for lower respiratory events (including asthma exacerbation and wheezing) was 0.98 (95% confidence interval 0.63-1.51) and the incidence rate ratio for upper respiratory events was 0.94 (95% confidence interval 0.48-1.86). The risk of lower respiratory events was similar for intermittent and mild persistent asthma, across age groups, and for seasonal trivalent LAIV and 2009 H1N1 pandemic monovalent LAIV. LAIV use in asthma was mostly in persons with intermittent or mild persistent asthma. LAIV was not associated with an increased risk of medically attended respiratory adverse events.

Tai, Teresa; Bame, Sherry I

2011-04-01

Asthma is a leading chronic illness among American children. School-based health clinics (SBHCs) reduced expensive ER visits and hospitalizations through better healthcare access and monitoring in select case studies. The purpose of this study was to examine the cost-benefit of SBHC programs in managing childhood asthma nationwide for reduction in medical costs of ER, hospital and outpatient physician care and savings in opportunity social costs of lowing absenteeism and work loss and of future earnings due to premature deaths. Eight public data sources were used to compare costs of delivering primary and preventive care for childhood asthma in the US via SBHC programs, including direct medical and indirect opportunity costs for children and their parents. The costs of nurse staffing for a nationwide SBHC program were estimated at $4.55 billion compared to the estimated medical savings of $1.69 billion, including ER, hospital, and outpatient care. In contrast, estimated total savings for opportunity costs of work loss and premature death were $23.13 billion. Medical savings alone would not offset the expense of implementing a SBHC program for prevention and monitoring childhood asthma. However, even modest estimates of reducing opportunity costs of parents' work loss would be far greater than the expense of this program. Although SBHC programs would not be expected to affect the increasing prevalence of childhood asthma, these programs would be designed to reduce the severity of asthma condition with ongoing monitoring, disease prevention and patient compliance.

Asthma severity, control, type of medical regimen provided, and compliance with it are not well understood in minority patients at the transition stage from childhood to adolescence. Describe the level of asthma severity and control and the clinical regimens provided to a large population of low-income, African American children at this developmentally significant period. Parents of 1292 children with asthma among 6827 preteens in 19 middle schools in predominantly African American (94%), low-income neighborhoods in Detroit, Michigan, were enrolled in the study. Data were collected through self-administered survey and telephone interviews and were useable for 936 participants. Study queries related to demographics, asthma symptoms, and medication use. Mixed effects models with a random intercept for school were used to determine severity and control and the association of medical regimens to these. Sixty-seven percent of children with probable asthma had received a physician's diagnosis. Being female was associated with being undiagnosed (p = .02). Forty-seven with no diagnosis had persistent asthma and 10% of these were classified as severe. Sixty-eight percent with a diagnosis and asthma medicine prescriptions were not controlled. Compliant use of controller medicine was associated with poorer asthma control compared to noncompliant controller users (p = .04) and reliever-only users (p < .001). Thirty-nine percent of children had controller medicine; of those 40% were not compliant with controller use; 9% nebulized their controller medicine. Care provided low-income minority children at an important stage in their development was not consistent with guidelines for asthma control. Therapy choices for treatment did not account for the actual level of their symptoms. Lack of an asthma diagnosis was significant in the population. Adolescent girls were at risk for not receiving a diagnosis. Patient compliance with asthma regimens was limited. Both clinician and patient education regarding effective asthma management appears needed regarding preteens in low-income minority communities.

The study aims to assess medication adherence and asthma management behaviors and their modifiable predictors in low-income children with persistent asthma. The authors conducted a cohort study of 143 children ages 6 to 11 prescribed a daily inhaled controller medicine that could be electronically monitored. Children were recruited from clinics or the emergency department of an urban children's hospital. Data were collected at baseline (T1) and 1 year later (T2). Outcome measures were adherence to controller medications as measured by electronic monitoring devices, observed metered-dose inhaler and spacer technique, exposure to environmental tobacco smoke, and attendance at appointments with primary health care provider. Medication adherence rates varied across medications, with higher rates for montelukast than for fluticasone. Eleven percent to 15% of children demonstrated metered dose inhaler and spacer technique suggesting no drug delivery, and few (5% to 6%) evidenced significant exposure to environmental tobacco smoke. Less than half of recommended health care visits were attended over the study interval. Few psychosocial variables were associated with adherence at T1 or in the longitudinal analyses. Fluticasone adherence at T2 was predicted by caregiver asthma knowledge. A substantial number of low-income children with persistent asthma receive less than half of their prescribed inhaled controller agent. Patients without Medicaid, with low levels of caregiver asthma knowledge, or with caregivers who began childrearing at a young age may be at highest risk for poor medication adherence.

Effects of tobacco smoke exposure on asthma prevalence and medical care use in North Carolina middle school children.

We sought to determine the effects of exposure to environmental tobacco smoke (ETS) and childhood cigarette smoking on asthma symptoms among middle school children in North Carolina. During 1999-2000, information was collected from a survey completed by the children. Outcomes of asthma symptom reporting were regressed on tobacco smoke exposures. Children who currently smoked or reported any exposure to ETS were at increased risk of reporting active asthma symptoms. Exposure to ETS and childhood cigarette smoking was responsible for 15% of the asthma cases observed in the study population and $1.34 million in excess medical expenditures. Even at low levels of exposure, childhood cigarette smoking and ETS are independently associated with asthmatic symptoms.

The objective of the study was to determine whether parents who use a low-literacy, pictogram- and photograph-based written asthma action plan (WAAP) have a better understanding of child asthma management compared to parents using a standard plan. A randomized controlled study was carried out in 2 urban pediatric outpatient clinics. Inclusion criteria were English- and Spanish-speaking parents of 2- to 12-year-old asthmatic children. Parents were randomized to receive a low-literacy or standard asthma action plan (American Academy of Allergy, Asthma and Immunology) for a hypothetical patient on controller and rescue medications. A structured questionnaire was used to assess whether there was an error in knowledge of (1) medications to give everyday and when sick, (2) need for spacer use, and (3) appropriate emergency response to give albuterol and seek medical help. Multiple logistic regression analyses were performed, adjusting for parent age, health literacy (Newest Vital Sign); child asthma severity, medications; and site. 217 parents were randomized (109 intervention and 108 control). Parents who received the low-literacy plan were (1) less likely to make an error in knowledge of medications to take everyday and when sick compared to parents who received the standard plan (63.0 vs. 77.3%, p = 0.03; adjusted odds ratio [AOR] = 0.5[95% confidence interval: 0.2-0.9]) and (2) less likely to make an error regarding spacer use (14.0 vs. 51.1%, p < 0.001; AOR = 0.1 [0.06-0.3]). No difference in error in appropriate emergency response was seen (43.1 vs. 48.1%, p = 0.5). Use of a low-literacy WAAP was associated with better parent understanding of asthma management. Further study is needed to assess whether the use of this action plan improves child asthma outcomes.

Although the asthma guidelines recommend inhaled corticosteroids(ICS) or leukotriene receptor antagonists-(LTRAs) for the treatment of mild persistent asthma, factors governing the physicians' preference are unknown. We aimed to investigate the preference of physicians for the controller medication and the factors governing their choice. A self-administered questionnaire composed of 16 questions that aimed to determine the preference of the physicians for the first choice controller medication in mild persistent asthma and physician and patient related factors that may be associated with this selection was e-mailed to the members of the Turkish National Society of Allergy and Clinical Immunology and distributed to participants in the 21st congress. Of the 670 questionnaires, there were 51% participants and 336 of them were complete enough to be included in the analysis. Low dose ICS was preferred as the first choice controller medication for mild persistent asthma by 84.5% of the physicians. The reasons for physicians' preference were different for ICS and LTRA. In the logistic regression analysis, use of asthma guidelines (OR:3.5, 95%CI:1.3-9.3, p = 0.01), alignment in guidelines (OR:2.9, 95%CI:1.4-5.8, p = 0.002) and the opinion that it is a more effective (OR:2.3, 95%CI:1.1-4.8, p = 0.02) were independently associated with ICS preference. Being a pediatrician (OR:5.4, 95%CI: 2.7-10.5, p < 0.001) and the opinion that it has better patient compliance (OR:4.4, 95%CI: 1.6-12.0, p = 0.004) were independently associated with LTRA preference. Surveyed Turkish physicians, the majority of whom were specialists, preferred ICS over LTRA as controller medication in mild persistent asthma. Asthma guidelines, training background (pediatrician versus not) and perceived efficacy and patient compliance appeared to influence their preferences. Copyright © 2017. Published by Elsevier Ltd.

In terms of immune regulating functions, analysis of the microbiome has led the development of therapeutic strategies that may be applicable to asthma management. This review summarizes the current literature on the gut and lung microbiota in asthma pathogenesis with a focus on the roles of innate molecules and new microbiome-mediated therapeutics. Recent clinical and basic studies to date have identified several possible therapeutics that can target innate immunity and the microbiota in asthma. Some of these drugs have shown beneficial effects in the treatment of certain asthma phenotypes and for protection against asthma during early life. Current clinical evidence does not support the use of these therapies for effective treatment of asthma. The integration of the data regarding microbiota with technologic advances, such as next generation sequencing and omics offers promise. Combining comprehensive bioinformatics, new molecules and approaches may shape future asthma treatment.

Asthma is a heterogeneous, complex disease with clinical phenotypes that incorporate persistent symptoms and acute exacerbations. It affects many millions of Europeans throughout their education and working lives and puts a heavy cost on European productivity. There is a wide spectrum of disease severity and control. Therapeutic advances have been slow despite greater understanding of basic mechanisms and the lack of satisfactory preventative and disease modifying management for asthma constitutes a significant unmet clinical need. Preventing, treating and ultimately curing asthma requires co-ordinated research and innovation across Europe. The European Asthma Research and Innovation Partnership (EARIP) is an FP7-funded programme which has taken a co-ordinated and integrated approach to analysing the future of asthma research and development. This report aims to identify the mechanistic areas in which investment is required to bring about significant improvements in asthma outcomes. Copyright ©ERS 2017.

Childhood marks the highest risk for allergic sensitization to asthma triggers. Hispanic/Latino children are at higher risk for hospitalization for asthma than non-Hispanic White children. Childcare providers lack knowledge about reducing asthma triggers. The purpose of this paper is to describe a community-based participatory research (CBPR) initiative aimed at developing and pilot testing a bilingual walk-through assessment tool for asthma-friendly childcare environments. Ten Latina mothers of children with asthma living in the Pacific Northwest collaborated with research partners to develop and pilot test a Childcare Environmental Health (CEH) assessment walk-through survey.Results and Lessons Learned: The women innovated the survey with photography and structural examinations of stress and provision of basic needs. The survey tool identified environmental threats to asthma in all three childcares surveyed. Parents are well-positioned to build trust with childcare providers, assess asthma triggers, and recommend practical mitigation strategies.

In the United States, asthma is the most common chronic disease of childhood across all socioeconomic classes and is the most frequent cause of hospitalization among children. Asthma exacerbations have been associated with exposure to residential indoor environmental stressors such as allergens and air pollutants as well as numerous additional factors. Simulation modeling is a valuable tool that can be used to evaluate interventions for complex multifactorial diseases such as asthma but in spite of its flexibility and applicability, modeling applications in either environmental exposures or asthma have been limited to date. We designed a discrete event simulation model to study the effect of environmental factors on asthma exacerbations in school-age children living in low-income multi-family housing. Model outcomes include asthma symptoms, medication use, hospitalizations, and emergency room visits. Environmental factors were linked to percent predicted forced expiratory volume in 1 second (FEV1%), which in turn was linked to risk equations for each outcome. Exposures affecting FEV1% included indoor and outdoor sources of NO2 and PM2.5, cockroach allergen, and dampness as a proxy for mold. Model design parameters and equations are described in detail. We evaluated the model by simulating 50,000 children over 10 years and showed that pollutant concentrations and health outcome rates are comparable to values reported in the literature. In an application example, we simulated what would happen if the kitchen and bathroom exhaust fans were improved for the entire cohort, and showed reductions in pollutant concentrations and healthcare utilization rates. We describe the design and evaluation of a discrete event simulation model of pediatric asthma for children living in low-income multi-family housing. Our model simulates the effect of environmental factors (combustion pollutants and allergens), medication compliance, seasonality, and medical history on asthma outcomes (symptom-days, medication use, hospitalizations, and emergency room visits). The model can be used to evaluate building interventions and green building construction practices on pollutant concentrations, energy savings, and asthma healthcare utilization costs, and demonstrates the value of a simulation approach for studying complex diseases such as asthma.

BACKGROUND: The Ontario Ministry of Health and Long-Term Care funded the Ontario Lung Association to develop and implement a continuing medical education program to promote implementation of the Canadian asthma guidelines in primary care. OBJECTIVES: To determine baseline knowledge, preferred learning format, satisfaction with the program and reported impact on practice patterns. METHODS: A 3 h workshop was developed that combined didactic presentations and small group case discussions. Outcome measures included a workshop evaluation, baseline assessment of asthma management knowledge and three-month postreflective evaluations. RESULTS: One hundred thirty-seven workshops were delivered to 2783 primary care providers (1313 physicians, 1470 allied health) between September 2002 and March 2005. Of the 2133 participants, 1007 physicians and 1126 allied health professionals submitted workshop evaluations. Most (98%) of the attendees indicated they would recommend the workshop to a colleague. The majority preferred the combination of didactic lecture plus interactive case discussions. A subset of physicians provided consent to use these data for research (n=298 pediatric and 288 adult needs assessments; n=349 postreflective evaluations). Important needs identified included appropriate medication for chronic asthma and development of written action plans. On the postreflective evaluations, 88.7% remained very satisfied, 95.5% reported increased confidence, 91.9% reported an influence on practice and 67.2% reported using a written action plan. CONCLUSIONS: This continuing medical education program addresses identified needs of primary care providers. Participants reported improvements in asthma care, including prescribing practices, use of spirometry and written action plans. Similar programs should be considered as part of multifaceted asthma guidelines dissemination and implementation initiatives in other provinces and nationally. PMID:17372639

Asthma-chronic obstructive pulmonary disease (COPD) overlap syndrome (ACOS) is defined as having both features of asthma and COPD, which are airway hyper-responsiveness and incompletely reversible airway obstruction. However, socioeconomic impact of ACOS have not been well appreciated. Adults with available wheezing history and acceptable spirometry were selected from the fourth Korean National Health and Nutrition Examination Survey (KNHANES IV) in 2007-2009. Their data were merged with the Korean National Health Insurance claim data. 'Asthma group' was defined as having self-reported wheezing history and FEV 1 /FVC ≥0.7, 'COPD group' was defined as having FEV 1 /FVC <0.7 and no wheezing, 'ACOS group' was defined as having both wheezing and FEV 1 /FVC <0.7, and 'no airway disease (NAD) group' was defined as having no wheezing and FEV 1 /FVC ≥0.7. Among a total of 11,656 subjects, ACOS comprise 2.2%; COPD, 8.4%; asthma, 5.8% and NAD, 83.6%. Total length of healthcare utilization and medical costs of ACOS group was the top among four groups (P<0.001), though inpatient medical cost was the highest in COPD group (P=0.025). Multiple linear regression analyses showed that ACOS group (β=12.63, P<0.001) and asthma group (β=6.14, P<0.001) were significantly associated with longer duration of healthcare utilization and ACOS group (β=350,475.88, P=0.008) and asthma group (β=386,876.81, P<0.001) were associated with higher medical costs. This study demonstrated that ACOS independently influences healthcare utilization after adjusting several factors. In order to utilize limited medical resources efficiently, it may be necessary to find and manage ACOS patients.

Despite previous findings of therapeutic effects for heart rate variability biofeedback (HRVB) on asthma, it is not known whether HRVB can substitute either for controller or rescue medication, or whether it affects airway inflammation. Sixty-eight paid volunteer steroid naïve study participants with mild or moderate asthma were given 3 months of HRVB or a comparison condition consisting of EEG alpha biofeedback with relaxing music and relaxed paced breathing (EEG+), in a two-center trial. All participants received a month of intensive asthma education prior to randomization. Both treatment conditions produced similar significant improvements on the methacholine challenge test (MCT), asthma symptoms, and asthma quality of life (AQOL). MCT effects were of similar size to those of enhanced placebo procedures reported elsewhere, and were 65% of those of a course of a high-potency inhaled steroid budesonide given to a sub-group of participants following biofeedback training. Exhaled nitric oxide decreased significantly only in the HRVB group, 81% of the budesonide effect, but with no significant differences between groups. Participants reported becoming more relaxed during practice of both techniques. Administration of albuterol after biofeedback sessions produced a large improvement in pulmonary function test results, indicating that neither treatment normalized pulmonary function as a potent controller medication would have done. Impulse oscillometry showed increased upper airway (vocal cord) resistance during biofeedback periods in both groups. These data suggest that HRVB should not be considered an alternative to asthma controller medications (e.g., inhaled steroids), although both biofeedback conditions produced some beneficial effects, warranting further research, and suggesting potential complementary effects. Various hypotheses are presented to explain why HRVB effects on asthma appeared smaller in this study than in earlier studies. Clinical Trial Registration NCT02766374.

[Allergic Rhinitis and its Impact on Asthma (ARIA) in Latin America].

Baena-Cagnani, Carlos E

Allergic rhinitis is the commonest chronic respiratory disorder in children and young adults having an important impact for those suffering this condition, as well as for the public health. Allergic rhinitis is frequently associated to other co-morbidities, particularly asthma and conjunctivitis but, also, sinusitis and otitis media. Most of patients suffering rhinitis are cared by GPs and pediatricians and there are evidences that allergic rhinitis is undertreated, particularly the moderate/severe persistent forms. Clinical guidelines have become an important tool providing recommendations for diagnosis and treatment of different medical conditions. They help the process of decision making for GPs and pediatricians, and many of them, contain an update on basic science and epidemiology. In respiratory medicine, guidelines on asthma and rhinitis are available; however, they do not look at the patients globally and focus the disorder on an organ-specific basis without recommendations on co-morbidities. ARIA, Allergic rhinitis and its impact on asthma, has not been developed only to update specialists in allergy/immunology, otorhinolaryngology and neumology on rhinitis and its comorbidities but, also, to provide recommendations for non-specialists. A new classification and severity of allergic rhinitis is proposed replacing the classic perennial and seasonal forms for persistent and intermittent, mild to moderate/severe. ARIA is an initiative in collaboration with the World Health Organization and the master document has been endorsed by many national and international scientific societies and organizations. ARIA is an evidence-based document also stressing on pediatric aspects and providing recommendations for low-income countries.

Asthma in intellectual disability: are we managing our patients appropriately?

PubMed Central

2016-01-01

People with intellectual disability are a vulnerable group of people with asthma that has, to date, largely been ignored in the medical literature. Although guidelines for medication management for people with intellectual disability suggest asthma is treated as for other populations, there are special considerations that should be taken into account when managing asthma in this group. Due to their cognitive impairment as well as comorbidities, they are likely to require support with asthma self-management, including inhaler use. Their varying degrees of autonomy mean that there is often a need to provide education and information to both the person and their caregivers. Educational aims To understand general principles of health of people with intellectual disability and how this affects the healthcare professional’s approach to asthma management. To understand how intellectual disability affects cognition, autonomy and communication, and therefore the ability of a person to self-manage asthma. To recognise ways of mitigating respiratory disease risk in people with intellectual disability. To describe ways for healthcare professionals to support people with intellectual disability and their caregivers in asthma management. PMID:28210318

Examining causes of the urban (inner city) asthma epidemic: Implementing new management strategies

PubMed Central

2016-01-01

Asthma in the inner city contributes to high morbidity and mortality, and, in school children, reduced school attendance and alteration in academic performance. There is a need to improve asthma care in the inner city by reducing asthma exacerbations. Methods are currently available to predict and prevent seasonal exacerbations of asthma. In addition, new medications are being developed that will be effective in improving pulmonary function and reducing asthma exacerbations. School-centered asthma programs can also be helpful to assist children and clinicians in applying asthma treatment plans and assuring optimal adherence to these plans. PMID:26831839

Asthma Morbidity, Comorbidities, and Modifiable Factors Among Older Adults.

PubMed

Hsu, Joy; Chen, Jessica; Mirabelli, Maria C

Asthma morbidity is increased among older adults, especially older adult women. Interventions to improve asthma control in this population are not well described. The objective of this study was to identify risk factors (including modifiable factors) associated with asthma-related hospitalizations and emergency department or urgent care center visits (ED/UCV) among older adults. A secondary objective was to investigate sex differences in variables relevant to asthma control. Data were obtained from 14,076 older adults ≥65 years with active asthma participating in the 2006-2010 Behavioral Risk Factor Surveillance System Asthma Call-back Survey (a random-digit dialed survey) in 40 US states, the District of Columbia, and Puerto Rico, representative of >2.6 million persons. Weighted, adjusted logistic regression was conducted. One or more asthma-related hospitalizations in the past year were reported by 5.7% (95% confidence interval [95% CI] = 5.0% to 6.4%) of participants; 10.6% (95% CI = 9.7% to 11.5%) reported ≥1 asthma-related ED/UCV. Compared with older adults without asthma-related hospitalizations, adjusted odds were higher among those with ≥1 asthma-related hospitalization for chronic obstructive pulmonary disease (COPD), coronary artery disease, depression, cockroaches or mold in the home, and cost barriers to asthma-related health care or medication. All these factors, except for cockroaches, were associated with asthma-related ED/UCV. Compared with males, adjusted odds were higher among females for COPD, depression, obesity, and cost barriers to asthma-related health care or medication. Among older adults, asthma-related hospitalizations and ED/UCV were associated with clinical comorbidities, mold in the home, and financial barriers to asthma-related health care. Interventions addressing modifiable factors could reduce asthma morbidity among older adults. Published by Elsevier Inc.

To demonstrate that school teachers can be taught to recognize respiratory distress in asthmatic children. Forty-five school teachers received a one-hour educational session on childhood asthma. Each education session consisted of two portions, video footage of asthmatic children exhibiting respiratory distress and didactic. Pre- and posttests on general asthma knowledge, signs of respiratory distress on video footage and comfort level with asthma knowledge and medications were administered. General asthma knowledge median scores increased significantly, pre = 60% correct, post = 70% (p < 0.0001). The ability to visually recognize respiratory distress also significantly improved (pre-median = 66.7% correct, post = 88.9% [p < 0.0001]). Teachers' comfort level with asthma knowledge and medications improved. Using video footage, school teachers can be taught to visually recognize respiratory distress in asthmatic children. Improvement in visual recognition of respiratory distress was greater than improvement in didactic asthma information.

2005-03-01

The aims of this survey were (1) to assess the quality of asthma treatment and control in Latin America, (2) to determine how closely asthma management guidelines are being followed, and (3) to assess perception, knowledge and attitudes related to asthma in Latin America. We surveyed a household sample of 2,184 adults or parents of children with asthma in 2003 in 11 countries in Latin America. Respondents were asked about healthcare utilization, symptom severity, activity limitations and medication use. Daytime asthma symptoms were reported by 56% of the respondents, and 51% reported being awakened by their asthma at night. More than half of those surveyed had been hospitalized, attended a hospital emergency service or made unscheduled emergency visits to other healthcare facilities for asthma during the previous year. Patient perception of asthma control did not match symptom severity, even in patients with severe persistent asthma, 44.7% of whom regarded their disease as being well or completely controlled. Only 2.4% (2.3% adults and 2.6% children) met all criteria for asthma control. Although 37% reported treatment with prescription medications, only 6% were using inhaled corticosteroids. Most adults (79%) and children (68%) in this survey reported that asthma symptoms limited their activities. Absence from school and work was reported by 58% of the children and 31% of adults, respectively. Asthma control in Latin America falls short of goals in international guidelines, and in many aspects asthma care and control in Latin America suffer from the same shortcomings as in other areas of the world.

Asthma, the sex difference.

PubMed

Kynyk, Jessica A; Mastronarde, John G; McCallister, Jennifer W

2011-01-01

asthma is a common chronic disease with significant clinical impact worldwide. Sex-related disparities in asthma epidemiology and morbidity exist but debate continues regarding the mechanisms for these differences. There is a need to review the recent findings for asthma care providers and to highlight areas in need of additional research. recent data illustrate striking sex-related differences in asthma epidemiology and disease expression. Studies show an increased incidence of asthma in women. Data demonstrate that asthmatic women have a poorer quality of life and increased utilization of healthcare compared to their male counterparts despite similar medical treatment and baseline pulmonary function. Research continues to explore hypotheses for these differences including the potential influences of the female sex hormones, altered perception of airflow obstruction, increased bronchial hyper-responsiveness, and medication compliance and technique. However, no single explanation has been able to fully explain the disparities. women are more likely to be diagnosed with asthma and suffer greater morbidity than men. The physiologic mechanisms for these differences are not well understood. Understanding sex-related differences in asthma and providing patients with education geared toward these disparities are important in establishing effective, individualized asthma management strategies for all patients.

To assess gaps in emergency department (ED) asthma management at Florida hospitals. Survey instrument with open- and closed-ended questions. Topics included availability of specific asthma management modalities, compliance with national guidelines, employment of specialized asthma care personnel, and efforts toward performance improvement. Emergency departments at 10 large hospitals in the state of Florida. Clinical care providers and health administrators from participating hospitals. Compliance with national asthma care guideline standards, provision of specific recommended treatment modalities and resources, employment of specialized asthma care personnel, and engagement in performance improvement efforts. Our results suggest inconsistency among sampled Florida hospitals' adherence to national standards for treatment of asthma in EDs. Several hospitals were refining their emergency care protocols to incorporate guideline recommendations. Despite a lack of formal ED protocols in some hospitals, adherence to national guidelines for emergency care nonetheless remained robust for patient education and medication prescribing, but it was weaker for formal care planning and medical follow-up. Identified deficiencies in emergency asthma care present a number of opportunities for strategic mitigation of identified gaps. We conclude with suggestions to help Florida hospitals achieve success with ED asthma care reform. Team-based learning activities may offer an optimal strategy for sharing and implementing best practices.

Abstract Objectives To describe the demand for emergency medical assistance during the largest outbreak of thunderstorm asthma reported globally, which occurred on 21 November 2016. Design A time series analysis was conducted of emergency medical service caseload between 1 January 2015 and 31 December 2016. Demand during the thunderstorm asthma event was compared to historical trends for the overall population and across specific subgroups. Setting Victoria, Australia. Main outcome measures Number of overall cases attended by emergency medical services, and within patient subgroups. Results On 21 November 2016, the emergency medical service received calls for 2954 cases, which was 1014 more cases than the average over the historical period. Between 6 pm and midnight, calls for 1326 cases were received, which was 2.5 times higher than expected. A total of 332 patients were assessed by paramedics as having acute respiratory distress on 21 November, compared with a daily average of 52 during the historical period. After adjustment for temporal trends, thunderstorm asthma was associated with a 42% (95% confidence interval 40% to 44%) increase in overall caseload for the emergency medical service and a 432% increase in emergency medical attendances for acute respiratory distress symptoms. Emergency transports to hospital increased by 17% (16% to 19%) and time critical referrals from general practitioners increased by 47% (21% to 80%). Large increases in demand were seen among patients with a history of asthma and bronchodilator use. The incidence of out-of-hospital cardiac arrest increased by 82% (67% to 99%) and pre-hospital deaths by 41% (29% to 55%). Conclusions An unprecedented outbreak of thunderstorm asthma was associated with substantial increase in demand for emergency medical services and pre-hospital cardiac arrest. The health impact of future events may be minimised through use of preventive measures by patients and predictive early warning systems. PMID:29237604

Obesity increases the prevalence and the incidence of asthma and worsens asthma severity.

We aimed to explore the association between obesity and asthma prevalence, incidence and severity. The study included 32,644 adults, 52.6% female, from a representative sample of the 4th Portuguese National Health Survey. The following asthma definitions were used: ever asthma (ever medical doctor asthma diagnosis), current asthma (asthma within the last 12 months), current persistent asthma (required asthma medication within the last 12 months), current severe asthma (attending an emergency department because of asthma within the last 12 months), and incident asthma (asthma diagnosis within the last 12 months). Body mass index was calculated based on self-reported weight and height and categorised according to WHO classification. Logistic regression models adjusted for confounders were performed. Prevalence of ever asthma was 5.3%, current asthma 3.5%, current persistent asthma 3.0%, current severe asthma 1.4%, and incident asthma 0.2%. Prevalence of obesity was 16%, overweight 37.6%, normal weight 44.6% and underweight 0.2%. Being overweight, obesity class I and II, and obesity class III were associated with an OR (95% CI) with ever asthma 1.22 (1.21-1.24), 1.39 (1.36-1.41), 3.24 (3.08-3.40) respectively; current asthma 1.16 (1.14-1.18), 1.86 (1.82-1.90), 4.73 (4.49-4.98) respectively; current persistent asthma 1.08 (1.06-1.10), 2.06 (2.01-2.10), 5.24 (4.96-5.53), and current severe asthma 1.36 (1.32-1.40), 1.50 (1.45-1.55) and 3.70 (3.46-3.95), respectively. Considering the incidence of asthma, obesity more than quadrupled the odds (OR = 4.46, 95% CI 4.30, 4.62). Obesity is associated in a dose dependent way with an increase of prevalent and incident asthma, and it seems to increase the odds of a more persistent and severe asthma phenotype independently of socio-demographic determinants, physical activity, and dietary patterns. Our results provide rational for future lifestyle intervention studies for weight reduction in the obesity-asthma phenotype.

To compare a step-down approach in well-controlled asthma patients, as recommended by treatment guidelines, from fluticasone propionate 250 microg twice daily (FP250 BID), or equivalent, to ciclesonide 160 microg once daily (CIC160 OD) with continued FP250 BID treatment. Patients with well-controlled asthma prior to study entry were included in two identical, randomized, double-blind, double-dummy, parallel-group studies. After a 2-week run-in period with FP250 BID, patients were randomized to CIC160 OD (n = 58) or FP250 BID (n = 53) for 12 weeks. Primary endpoints were percentage of days with asthma control, asthma symptom-free days, rescue medication-free days and nocturnal awakening-free days. Secondary endpoints included lung function variables, asthma symptom scores, rescue medication use and asthma exacerbations. Safety variables were also recorded. Patients had >or= 97% of days with asthma control, 98% asthma symptom-free days and 100% of days free from rescue medication use and nocturnal awakenings in both treatment groups (median values). There were no significant between-treatment differences for any of the primary or secondary efficacy variables. Overall, 42 treatment-emergent adverse events (TEAEs) were reported in the CIC160 OD group and 49 TEAEs were reported in the FP250 BID group. There were no clinically relevant changes from baseline in the safety variables in either treatment group. Patients well controlled on FP250 BID, or equivalent, who were stepped down to CIC160 OD, maintained similar asthma control compared with patients who received continued treatment standardized to FP250 BID.

This study examines: 1) adolescent preferences for using asthma self-management mobile applications (apps) to interact with their friends, caregivers, medical providers, and other adolescents with asthma and 2) how caregivers and friends would use mobile apps to communicate with the adolescent and serve as sources of support for asthma management. We recruited 20 adolescents aged 12-16 years with persistent asthma, their caregivers (n = 20), and friends (n = 3) from two suburban pediatric practices in North Carolina. We gave participants iPods with two preloaded asthma apps and asked them to use the apps for 1 week. Adolescents and caregivers provided app feedback during a semi-structured interview at a regularly-scheduled clinic appointment and during a telephone interview one week later. Friends completed one telephone interview. Interviews were audio-recorded and transcribed verbatim. An inductive, theory-driven analysis was used to identify themes and preferences. Adolescents preferred to use apps for instrumental support from caregivers, informational support from friends, and belonging and informational support from others with asthma. The majority of adolescents believed apps could enhance communication with their caregivers and medical providers, and the theme of self-reliance emerged in which caregivers and adolescents believed apps could enable adolescents to better self-manage their asthma. Friends preferred to use apps to provide instrumental and informational support. Given preferences expressed in this study, apps may help adolescents obtain social support to better self-manage their asthma. Future app-based interventions should include features enabling adolescents with asthma to communicate and interact with their caregivers, medical providers, and friends.

Disparities in asthma outcomes are well documented in the United States. Interventions to promote equity in asthma outcomes could target factors at the individual and community levels. The objective of this analysis was to understand the effect of individual (race, gender, age, and preventive inhaler use) and county-level factors (demographic, socioeconomic, health care, air-quality) on asthma emergency department (ED) visits among Medicaid-enrolled children. This was a retrospective cohort study of Medicaid-enrolled children with asthma in 29 states in 2009. Multilevel regression models of asthma ED visits were constructed utilizing individual-level variables (race, gender, age, and preventive inhaler use) from the Medicaid enrollment file and county-level variables reflecting population and health system characteristics from the Area Resource File (ARF). County-level measures of air quality were obtained from Environmental Protection Agency (EPA) data. The primary modifiable risk factor at the individual level was found to be the ratio of long-term controller medications to total asthma medications. County-level factors accounted for roughly 6% of the variance in the asthma ED visit risk. Increasing county-level racial segregation (OR=1.04, 95% CI=1.01-1.08) was associated with increasing risk of asthma ED visits. Greater supply of pulmonary physicians at the county level (OR=0.81, 95% CI=0.68-0.97) was associated with a reduction in risk of asthma ED visits. At the patient care level, proper use of controller medications is the factor most amenable to intervention. There is also a societal imperative to address negative social determinants, such as residential segregation.

Several factors have been accused for asthma exacerbations, however, very few studies have evaluated whether different factors predict severity of asthma exacerbation. We aimed to determine the predictive factors for severity of asthma exacerbation. Retrospective analysis of data on 93 patients visited our emergency-department because of asthma exacerbation was reviewed. Hospitalization in intensive care unit and/or intubation because of asthma was accepted as the criteria for severe exacerbation. Logistic regression analysis estimated the strength of association of each variable, potentially related to severe asthmatic exacerbation, with severe/very severe as compared to mild/moderate asthmatic exacerbation. Independent variables included in the analysis were age, sex, smoking history, inhaler steroid using, compliance with medication, chronic asthma severity, presence of additional atopic diseases, prick test positivity, provocative factors, number of short-acting beta(2)-agonist using, number of visits to emergency department for asthma over one year period, previous severe exacerbation, pulmonary functions, and blood eosinophil count. 20 were severe/very severe and 73 mild/moderate asthmatic exacerbation. Frequent using of short-acting beta(2)-agonist (OR= 1.5, 95% CI= 1.08-5.3, p= 0.003), noncompliance with medication (OR= 3.6, 95% CI= 1.3-9.9, p= 0.013), previous severe asthmatic exacerbation (OR= 3.8, 95% CI= 1.48-10.01, p= 0.005) and recent admission to hospital (OR= 2.9, 95% CI= 1.07-8.09, p= 0.037) were found to be predictive factors for severe asthmatic exacerbation. Different predictive factors, in particular frequent using of short-acting beta(2)-agonist and noncompliance with medication may be associated with severe asthma exacerbations compared to milder exacerbations. This suggests different mechanisms are responsible for severity of asthma exacerbation.

To estimate the association between obesity and poor asthma control or risk of exacerbations in asthmatic children and adolescents, and to assess whether these associations are different by sex.A meta-analysis was performed on unpublished data from three North-European paediatric asthma cohorts (BREATHE, PACMAN (Pharmacogenetics of Asthma medication in Children: Medication with Anti-inflammatory effects) and PAGES (Pediatric Asthma Gene Environment Study)) and 11 previously published studies (cross-sectional and longitudinal studies). Outcomes were poor asthma control (based on asthma symptoms) and exacerbations rates (asthma-related visits to the emergency department, asthma-related hospitalisations or use of oral corticosteroids). Overall pooled estimates of the odds ratios were obtained using fixed- or random-effects models.In a meta-analysis of 46 070 asthmatic children and adolescents, obese children (body mass index ≥95th percentile) compared with non-obese peers had a small but significant increased risk of asthma exacerbations (OR 1.17, 95% CI 1.03-1.34; I 2 : 54.7%). However, there was no statistically significant association between obesity and poor asthma control (n=4973, OR 1.23, 95% CI 0.99-1.53; I 2 : 0.0%). After stratification for sex, the differences in odds ratios for girls and boys were similar, yet no longer statistically significant.In asthmatic children, obesity is associated with a minor increased risk of asthma exacerbations but not with poor asthma control. Sex does not appear to modify this risk. Copyright ©ERS 2016.

Patient care based on asthma guidelines is cost-effective and leads to improved treatment outcomes. However, ineffective implementation strategies interfere with the use of these recommendations in clinical practice. This study investigated physicians' preferences for asthma guidelines, including content, supporting evidence, learning strategies, format, and placement in the clinical workplace. We obtained information through a questionnaire survey. The questionnaire was distributed to physicians attending continuing medical education courses and sent to other physicians by airmail, e-mail, and facsimile. A total of 183 physicians responded (male to female ratio, 2.3:1; mean age, 40.4±9.9 years); 89.9% of respondents were internists or pediatricians, and 51.7% were primary care physicians. Physicians preferred information that described asthma medications, classified the disease according to severity and level of control, and provided methods of evaluation/treatment/monitoring and management of acute exacerbation. The most effective strategies for encouraging the use of the guidelines were through continuing medical education and discussions with colleagues. Physicians required supporting evidence in the form of randomized controlled trials and expert consensus. They preferred that the guidelines be presented as algorithms or flow charts/flow diagrams on plastic sheets, pocket cards, or in electronic medical records. This study identified the items of the asthma guidelines preferred by physicians in Korea. Asthma guidelines with physicians' preferences would encourage their implementation in clinical practice.

Feasibility of a novel mHealth management system to capture and improve medication adherence among adolescents with asthma.

2016-01-01

Currently, 7.1 million children in the United States have asthma. Nonadherence to daily controller asthma medication is common, leading to more severe symptoms, overuse of rescue medication, and increased hospitalizations. The purpose of this study was to develop and evaluate the feasibility and acceptability of a novel mHealth management system composed of a sensored device, which is connected to mobile phone app that is designed to monitor and improve asthma medication adherence. The asthma management system was designed using well-established behavioral theory. Seven adolescents aged 11-18 years were enrolled and given an adherence sensor, and four of those also received a mobile phone app with game features and reminders. Five patients completed the study, and one was lost to follow-up in each group. Mobile app users and their parents participated in focus groups to assess patient preferences. Feasibility was assessed by the ability of sensors to capture real-time medication data. Acceptability was assessed by patient questionnaire and focus group analysis. Successful upload of real-time data from six of seven inhaler sensors to the HIPAA-compliant server demonstrates the feasibility of at-home patient monitoring using the sensor device. All three mobile app users who completed the study reported interest in continued use of the management system and would recommend the app to friends. Unstructured interviews and focus groups revealed that patients felt that the intervention helped their sense of asthma control. This study demonstrates the feasibility of using the sensor device to remotely monitor real-time medication usage, and user feedback demonstrates the acceptability of the intervention for patient use. The findings provide guidance for the improvement of study design and technology development. Further research is needed to assess the efficacy of the intervention.

Achieving Symptom Control in Patients with Moderate Asthma

PubMed Central

Weir, Nargues A.; Levine, Stewart J.

2012-01-01

Disease severity in asthma can be classified as mild, moderate or severe based upon the frequency of symptoms or the severity of airflow obstruction. This review will focus on the treatment of youths greater than 12 years of age and adults with moderate persistent asthma. Moderate asthmatics may have daily symptoms that cause some limitation with normal daily activities and require use of a rescue inhaled short-acting beta2-agonist inhaler or experience nocturnal awakenings secondary to asthma that occur more than once per week. Furthermore, spirometry may reveal airflow obstruction with a reduction in FEV1 to between 60% and 80% of predicted. Although inhaled corticosteroids (ICS) are the primary controller medication used to modify symptoms in moderate asthmatics, additional controller medications, such as inhaled long-acting beta2-agonists (LABA), leukotriene receptor antagonists (LTRA) or theophylline, are often needed to obtain optimal disease control. While the addition of an inhaled LABA to an ICS is very effective at improving disease control in moderate asthma, concerns have arisen over the safety of LABAs, in particular the risk of asthma-related death. Therefore, consideration may be given to initially adding a LTRA, rather than a LABA, to ICS when asthma symptoms are not adequately controlled by ICS alone. Furthermore, individualization of medication regimens, treatment of co-morbid conditions, and patient education are crucial to optimizing compliance with therapy, improving disease control, and reducing the risk of exacerbations. Lastly, the development of new asthma treatments, perhaps based upon personalized medicine, may revolutionize the future treatment of moderate asthma. PMID:22259262

[Nursing care of a school-age child with asthma: an ecological system theory approach].

2012-02-01

This research applied the Ecological System Theory of Dr. Bronfenbrenner (1979) to evaluate and analyze the impact of a school-age asthmatic child's ecological environment on the child's development. This project ran from March 16th to April 16th, 2010. A full range of data was collected during clinical care, outpatient follow-up services, telephone interviews, home visits, and school visits and then identified and analyzed. Results indicated that the family, household environment, campus, teachers, classmates, physical education program, and medical staffs comprised the most immediate microsystem and that parents, school nurses, teachers, and classmates formed the child's mesosystem. Researchers found a lack of understanding and appreciation in the mesosystem regarding asthmatic patient care needs. Hidden factors in the environment induced asthma, which eventually caused the child to be unable to obtain necessary medical care assistance. The exosystem reflected adequacy of the family social economy. The father's flexible working hours allowed him to allocate more time to childcare responsibilities. The government Asthma Medical Payment program also facilitated effective care. The macrosystem demonstrated parental cognition related to asthma treatment and caring to be deeply influenced by local customs. Thus, rather than using advanced medical treatments, parents preferred to follow traditional Chinese medicinal practices. Evaluation using the Ecological of Human Development Theory showed the subject's ecology environment relationships as based upon a foundation of family and school. Therefore, active family and school support for an asthma management plan appropriate to the subject's needs was critical. Asthma symptoms were better controlled after the child and his parents invested greater effort in mastering asthma management protocols.

Subjective social status (SSS) is a person's perception of his/her social standing among others. We explored the relationship between caregivers' SSS and asthma symptoms, visits, and medication use among children with persistent asthma. We analyzed baseline data of children (3-10 years) from the SB-TEAM trial in Rochester, NY. Using a modified MacArthur Scale of SSS, caregivers rated themselves "a lot worse off" to "a lot better off" compared to 4 groups (e.g., neighbors). "Low SSS" was defined by a response of "a lot worse off" or "somewhat worse off" for any of the referent groups. Caregivers reported their child's asthma symptoms, healthcare visits for asthma, and medication use. Bivariate and multivariate statistics were used. We found that, of the 230 children enrolled (participation rate:78%, 62% Black, 72% Medicaid), 29% of caregivers had low SSS. Caregivers with low SSS had more depressive symptoms (46% vs. 28%) and lower social support (69.1 vs. 77.7). In multivariable analyses, children of caregivers with low SSS had fewer symptom-free days/2 weeks (5.8 vs. 7.9, p = .01). While they were more likely to have a routine asthma visit in the past year (35% vs. 23%, adjusted p = .03), there was no difference in their use of preventive medication. Many caregivers of children with persistent asthma report low SSS. While children of these caregivers had fewer symptom-free days, they were not more likely to use preventive medications. Efforts are needed to support these caregivers to ensure optimal preventive care and reduce morbidity.

Despite significant advances in treatment modalities, morbidity due to childhood asthma has continued to increase, particularly for poor and minority children. To describe the parental illness representation of asthma in juxtaposition to the professional model of asthma and to evaluate the impact of that illness representation on the adequacy of the child's medication regimen. Parents (n = 228) of children with asthma were interviewed regarding illness beliefs using a semistructured interview. The impact of background characteristics, parental beliefs, the child's symptom interpretation, and the parent-healthcare provider (HCP) relationship on the adequacy of the child's medication regimen were evaluated. The parental and professional models of asthma differ markedly. Demographic risk factors (p = .005), low parental education (p < .0001), inaccurate symptom evaluation by the child (p = .02), and a poor parent-HCP relationship (p < .0001) had a negative effect on the parental illness representation. A parental illness representation concordant with the professional model of asthma (p = .05) and more formal asthma education (p = .02) had a direct positive effect on the medication regimen. Demographic risk factors (p = .006) and informal advice-seeking (p = .0003) had a negative impact on the regimen. The parental illness representation mediated the impact of demographic risk factors (p = .10), parental education (p =.07), and the parent-HCP relationship (p = .06) on the regimen. Parents and HCPs may come to the clinical encounter with markedly different illness representations. Establishing a partnership with parents by eliciting and acknowledging parental beliefs is an important component of improving disease management.

The objective of this study was to identify the types of interactions between asthma patients and their social networks such as close family and friends that influence the management of asthma. Participants were Latino adults presenting for a repeat visit to the emergency department for asthma treatment. Qualitative interviews were conducted with 76 participants. They were asked to describe the experiences of their social networks that have asthma and how interactions with these individuals influenced their own asthma management. Responses were transcribed and analyzed using Grounded Theory as a qualitative analytic approach. Responses were assigned codes; similar codes were grouped into concepts and then categorized to form overarching themes. Four themes emerged: (1) Perceptions of severity of asthma may be based on the experiences of social networks; (2) Economic factors may contribute to the sharing and borrowing of asthma medications between patients and their social networks; (3) Economic factors may contribute to using home remedies instead of prescribed medications; (4) Social network members may be unaware of the factors that trigger asthma and therefore, contribute to asthma exacerbations. This study identified important social network interactions that may impact asthma management in Latino adults. These results can be used to broaden the current focus of asthma self-management programs to incorporate discussions on the role of social networks. A focus on social network interactions addresses the social epidemiology of asthma and advances our understanding of root causes that may underlie the high prevalence of asthma in many Latino communities.

Non-adherence to asthma daily controller medications is a common problem, reported to be responsible for 60% of asthma-related hospitalisations. The mean level of adherence for asthma medications is estimated to be as low as 22%. Therefore, objective measurements of adherence to medicine are necessary. This virtual observational study is designed to measure the usability of an electronic monitoring device platform that measures adherence. Understanding how patients use the BreatheSmart mobile technology at home is essential to assess its feasibility as a solution to improve medication adherence. We anticipate this approach can be applied to real-world environments as a cost-effective solution to improve medication adherence. This is a virtual 6-month observational study of 100 adults (≥18 years) with an asthma diagnosis, using inhaled corticosteroids for at least 3 months. Participants will be recruited in the USA through ad placements online. All participants receive wireless Bluetooth-enabled inhaler sensors that track medication usage and an mSpirometer TM capable of clinical-grade lung function measurements, and download the BreatheSmart mobile application that transmits data to a secure server. All analyses are based on an intention-to-treat. Usability is assessed by patient questionnaires and question sessions. Simple paired t-test is used to assess significant change in Asthma Control Test score, quality of life (EuroQol-5D questionnaire) and lung function. No ethical or safety concerns pertain to the collection of these data. Results of this research are planned to be published as soon as available. NCT03103880.

Kassem, A; Hamad, M; El Moucary, C

2015-08-01

In this paper an innovative prototype for smart asthma spirometry device to be used by doctors and asthma patients is presented. The novelty in this prototype relies in the fact that it is destined to subtend not only adults but offers an efficient and attractive manner to accommodate children patients as well thus, making it efficient for doctors, patients and parents to detect and monitor such intricate cases at stages as early as six years old. Moreover, the apparatus used enables us to integrate a vital parameter representing the Forced Expiratory Volume to the final diagnosis. Besides, the presented device will automatically diagnose those patients, assess their asthma condition, and schedule their medication process without excessive visits to medical centers whilst providing doctors with accurate and pertinent and comprehensive medical data in a chronological fashion. Zooming into under the hood of the device, a fully reliable hardware digital system lies along with a flowmeter detector and a Bluetooth emitter to interface with a user-friendly GUI-based application installed on smartphones which incorporates appealing animated graphics to encourage children to take the test. Furthermore, the device offers the capability of storing chronological data and a relevant resourceful display for accurate tracking of patients' medical record, the evolvement of their asthma condition, and the administered medication. Finally, the entire device is aligned with the medical requirements as per doctors' and telemedicine specialists' recommendations; the experiments carried out demonstrated the effectiveness and sustainable use of such device.

Confidential enquiries into asthma deaths can identify inadequacies in medical management and factors which contribute to patients' death. To identify risk factors for paediatric asthma deaths over a 6-year period. Observational case-series study of paediatric asthma deaths between 2001-2006 in the UK Eastern Region. Hospital, primary care and post-mortem data were obtained for every child (≤17 yrs) with asthma recorded on the death certificate, and a detailed questionnaire was completed. Information was obtained on asthma severity, medications, hospital admissions, GP and hospital follow-up, adherence, psychosocial / behavioural factors, allergies, details of the terminal attack and precipitating factors. 20 children (10 male; 8-17 yrs; median: 11.5 yrs) died of asthma between 2001-2006. 9/20 had mild to moderate asthma (BTS/ SIGN criteria), 10/20 had severe asthma and 1 child was not known to have asthma. 13/20 were clinically atopic. Only 3 had undergone allergy assessment. 10/20 died between June and August. 12/20 children had adverse psychosocial and behavioural factors. 7/20 children were on non-combination long-acting β2-agonist (LABA) treatment without inhaled corticosteroids (ICS). Almost half the deaths occurred in children with mild/moderate asthma. We recommend that allergic factors and seasonal allergy should be identified early, non-combination LABAs avoided, and speculate that overuse of short-acting β2-agonists (SABAs) may indicate non-adherence with ICS. Asthma deaths in children can be avoided if risk factors are identified early.

Inner-city, minority children with asthma have the highest rates of morbidity and death from asthma and the lowest rates of asthma controller medication adherence. Some recent electronic medication monitoring interventions demonstrated dramatic improvements in adherence in lower-risk populations. The feasibility and acceptability of such an intervention in the highest-risk children with asthma has not been studied. Our objective was to assess the feasibility and acceptability of a community health worker-delivered electronic adherence monitoring intervention among the highest utilizers of acute asthma care in an inner-city practice. This was a prospective cohort pilot study targeting children with the highest frequency of asthma-related emergency department and hospital care within a local managed care Medicaid plan. The 3-month intervention included motivational interviewing, electronic monitoring of controller and rescue inhaler use, and outreach by a community health worker for predefined medication alerts. We measured acceptability by using a modified technology acceptability model and changes in asthma control using the Asthma Control Test (ACT). Given prominent feasibility issues, we describe qualitative patterns of medication use at baseline only. We enrolled 14 non-Hispanic black children with a median age of 3.5 years. Participants averaged 7.8 emergency or hospital visits in the year preceding enrollment. We observed three distinct patterns of baseline controller use: 4 patients demonstrated sustained use, 5 patients had periodic use, and 5 patients lapsed within 2 weeks. All participants initiated use of the electronic devices; however, no modem signal was transmitted for 5 or the 14 participants after a mean of 45 days. Of the 9 (64% of total) caregivers who completed the final study visit, all viewed the electronic monitoring device favorably and would recommend it to friends, and 5 (56%) believed that the device helped to improve asthma control. ACT scores improved by a mean of 2.7 points (P=.05) over the 3-month intervention. High-utilizer, minority families who completed a community health worker-delivered electronic adherence intervention found it generally acceptable. Prominent feasibility concerns, however, such as recruitment, data transmission failure, and lost devices, should be carefully considered when designing interventions in this setting.

Rationale: Asthma clinical guidelines suggest written asthma action plans are essential for improving self-management and outcomes. Objectives: To assess the efficacy of written instructions in the form of a written asthma action plan provided by subspecialist physicians as part of usual asthma care during office visits. Methods: A total of 407 children and adults with persistent asthma receiving first-time care in pulmonary and allergy practices at 4 urban medical centers were randomized to receive either written instructions (n = 204) or no written instructions other than prescriptions (n = 203) from physicians. Measurements and Main Results: Using written asthma action plan forms as a vehicle for providing self-management instructions did not have a significant effect on any of the primary outcomes: (1) asthma symptom frequency, (2) emergency visits, or (3) asthma quality of life from baseline to 12-month follow-up. Both groups showed similar and significant reductions in asthma symptom frequency (daytime symptoms [P < 0.0001], nocturnal symptoms [P < 0.0001], β-agonist use [P < 0.0001]). There was also a significant reduction in emergency visits for the intervention (P < 0.0001) and control (P < 0.0006) groups. There was significant improvement in asthma quality-of-life scores for adults (P < 0.0001) and pediatric caregivers (P < 0.0001). Conclusions: Our results suggest that using a written asthma action plan form as a vehicle for providing asthma management instructions to patients with persistent asthma who are receiving subspecialty care for the first time confers no added benefit beyond subspecialty-based medical care and education for asthma.

Margellos-Anast, Helen; Gutierrez, Melissa A; Whitman, Steven

2012-05-01

Asthma affects 25-30% of children living in certain disadvantaged Chicago neighborhoods, a rate twice the national prevalence (13%). Children living in poor, minority communities tend to rely heavily on the emergency department (ED) for asthma care and are unlikely to be properly medicated or educated on asthma self-management. A pilot project implemented and evaluated a community health worker (CHW) model for its effectiveness in reducing asthma morbidity and improving the quality of life among African-American children living in disadvantaged Chicago neighborhoods. Trained CHWs from targeted communities provided individualized asthma education during three to four home visits over 6 months. The CHWs also served as liaisons between families and the medical system. Seventy children were enrolled into the pilot phase between 15 November 2004 and 15 July 2005, of which 96% were insured by Medicaid and 54% lived with a smoker. Prior to starting, the study was approved by an institutional review board. Data on 50 children (71.4%) who completed the entire 12-month evaluation phase were analyzed using a before and after study design. Findings indicate improved asthma control. Specifically, symptom frequency was reduced by 35% and urgent health resource utilization by 75% between the pre- and post-intervention periods. Parental quality of life also improved by a level that was both clinically and statistically significant. Other important outcomes included improved asthma-related knowledge, decreased exposure to asthma triggers, and improved medical management. The intervention was also shown to be cost-effective, resulting in an estimated $5.58 saved per dollar spent on the intervention. Findings suggest that individualized asthma education provided by a trained, culturally competent CHW is effective in improving asthma management among poorly controlled, inner-city children. Further studies are needed to affirm the findings and assess the model's generalizability.

Background HMO databases offer an opportunity for community based epidemiologic studies of asthma incidence, etiology and treatment. The incidence of asthma in HMO populations and the utility of HMO data, including use of computerized algorithms and manual review of medical charts for determining etiologic factors has not been fully explored. Methods We identified adult-onset asthma, using computerized record searches in a New England HMO. Monthly, our software applied exclusion and inclusion criteria to identify an "at-risk" population and "potential cases". Electronic and paper medical records from the past year were then reviewed for each potential case. Persons with other respiratory diseases or insignificant treatment for asthma were excluded. Confirmed adult-onset asthma (AOA) cases were defined as those potential cases with either new-onset asthma or reactivated mild intermittent asthma that had been quiescent for at least one year. We validated the methods by reviewing charts of selected subjects rejected by the algorithm. Results The algorithm was 93 to 99.3% sensitive and 99.6% specific. Sixty-three percent (n = 469) of potential cases were confirmed as AOA. Two thirds of confirmed cases were women with an average age of 34.8 (SD 11.8), and 45% had no evidence of previous asthma diagnosis. The annualized monthly rate of AOA ranged from 4.1 to 11.4 per 1000 at-risk members. Physicians most commonly attribute asthma to infection (59%) and allergy (14%). New-onset cases were more likely attributed to infection, while reactivated cases were more associated with allergies. Medical charts included a discussion of work exposures in relation to asthma in only 32 (7%) cases. Twenty-three of these (72%) indicated there was an association between asthma and workplace exposures for an overall rate of work-related asthma of 4.9%. Conclusion Computerized HMO records can be successfully used to identify AOA. Manual review of these records is important to confirm case status and is useful in evaluation of provider consideration of etiologies. We demonstrated that clinicians attribute most AOA to infection and tend to ignore the contribution of environmental and occupational exposures. PMID:12952547

Potential negative consequences of non-consented switch of inhaled medications and devices in asthma patients.

2013-09-01

Asthma requires individually tailored and careful management to control and prevent symptoms and exacerbations. Selection of the most appropriate treatment is dependent on both the choice of drugs and inhaler device; however, financial pressures may result in patients being switched to alternative medications and devices in an attempt to reduce costs. This review aimed to examine the published literature in order to ascertain whether switching a patient's asthma medications or device negatively impacts clinical and economic outcomes. A literature search of MEDLINE (2001-13 September 2011) was conducted to identify English-language articles focused on the direct impact of switching medications and inhaler devices and switching from fixed-dose combination to monocomponent therapy via separate inhalers in patients with asthma; the indirect impacts of switching were also assessed. Evidence showed that non-consented switching of medications and inhalers in patients with asthma can be associated with a range of negative outcomes, at both individual and organisational levels. Factors that reduce adherence may lead to compromised symptom control resulting in increased healthcare resource utilisation and poorer patient quality of life. The consequences of a non-consented switch should be weighed carefully against arguments supporting an inhaler switch without the patient's consent for non-medical/budgetary reasons, such as potential reductions in initial acquisition costs, which may be associated with subsequent additional healthcare needs. Given the increasing pressure for reduced costs and efficient allocation of limited healthcare resources, an additional investment in ensuring high medication adherence may lead to greater savings due to a potentially decreased demand for healthcare services. In contrast, savings achieved in acquisition costs may result in a greater net loss due to increased healthcare consumption caused by decreased asthma control. © 2013 The Authors.

Bereznicki, B; Peterson, G; Jackson, S; Walters, E H; Gee, P

2011-04-01

A previously published asthma intervention used a software application to data mine pharmacy dispensing records and generate a list of patients with potentially suboptimal management of their asthma; in particular, a high rate of provision of reliever medication. These patients were sent educational material from their community pharmacists and advised to seek a review of their asthma management from their general practitioner. The intervention resulted in a 3-fold improvement in the ratio of dispensed preventer medication (inhaled corticosteroids) to reliever medication (short-acting beta-2 agonists). This follow-up study aimed to determine the long-term effects of the intervention programme on the preventer-to-reliever (P:R) ratio. The same data mining software was modified so that it could re-identify patients who were originally targeted for the intervention. Community pharmacists who participated in the previous intervention installed the modified version of the software. The dispensing data were then de-identified, encrypted and transferred via the Internet to a secure server. The follow-up dispensing data for all patients were compared with their pre- and post-intervention data collected originally. Of the 1551 patients who were included in the original study, 718 (46·3%) were eligible to be included in the follow-up study. The improved P:R ratio was sustained for at least 12 months following the intervention (P < 0·01). The sustained increase in the P:R ratio was attributed to significant decreases in the average daily usage of reliever medication (P < 0·0001). The follow-up study demonstrated a sustained improvement in the ratio of dispensed preventer medication to reliever medication for asthma. The intervention has the potential to show long-lasting and widespread improvements in asthma management, improved health outcomes for patients, and ultimately, a reduced burden on the health system. © 2010 Blackwell Publishing Ltd.

The Principal and Nurse Perspective on Gaps in Asthma Care and Barriers to Physical Activity in New York City Schools: A Qualitative Study.

School officials and nurses play an important role in facilitating asthma management in schools. Little is known about their perspectives on in-school asthma management and barriers to physical activity (PA) at school. The goal of this study is to explore school officials' and nurses' perspectives on asthma care and barriers to PA in children with asthma attending New York City schools. We conducted qualitative, semistructured interviews with 10 principals, 3 assistant principals, and 9 nurses in 10 Bronx, New York elementary schools. Sampling continued until thematic saturation was reached. Interviews were recorded, transcribed, and coded for common themes. The thematic and content review was subsequently used to analyze interview data. Emerging themes were discussed and agreed on by both investigators. Three main categories arose from the analysis: (1) procedures and policies around asthma management in school, (2) barriers to effective medication administration in school, and (3) barriers to PA in children with asthma. Participants identified gaps to in-school asthma management and barriers to PA participation: ineffective ways of identifying students with asthma; lack of written procedures for asthma management; difficulty in meeting the administrative requirements to administer asthma medication; lack of knowledge and training on asthma management for the parents, students, and school staff; parental limitation of children's PA; and schools not meeting the state physical education requirement. Our findings suggest the need for policy reform on asthma management and PA in urban schools and should be considered in the design of future interventions.

The public health implications of asthma.

Asthma is a very common chronic disease that occurs in all age groups and is the focus of various clinical and public health interventions. Both morbidity and mortality from asthma are significant. The number of disability-adjusted life years (DALYs) lost due to asthma worldwide is similar to that for diabetes, liver cirrhosis and schizophrenia. Asthma management plans have, however, reduced mortality and severity in countries where they have been applied. Several barriers reduce the availability, affordability, dissemination and efficacy of optimal asthma management plans in both developed and developing countries. The workplace environment contributes significantly to the general burden of asthma. Patients with occupational asthma have higher rates of hospitalization and mortality than healthy workers. The surveillance of asthma as part of a global WHO programme is essential. The economic cost of asthma is considerable both in terms of direct medical costs (such as hospital admissions and the cost of pharmaceuticals) and indirect medical costs (such as time lost from work and premature death). Direct costs are significant in most countries. In order to reduce costs and improve quality of care, employers and health plans are exploring more precisely targeted ways of controlling rapidly rising health costs. Poor control of asthma symptoms is a major issue that can result in adverse clinical and economic outcomes. A model of asthma costs is needed to aid attempts to reduce them while permitting optimal management of the disease. This paper presents a discussion of the burden of asthma and its socioeconomic implications and proposes a model to predict the costs incurred by the disease. PMID:16175830

Systematic Review and Meta-Analysis of Anxious and Depressive Symptoms in Caregivers of Children With Asthma.

Easter, Gemma; Sharpe, Louise; Hunt, Caroline J

2015-08-01

To provide a review of the literature comparing anxious and depressive symptoms in caregivers of children with asthma with caregivers of healthy children. A systematic search identified 25 studies from 17 articles, reporting outcomes on 4,300 caregivers of children with asthma and 25,064 caregivers of healthy children. Overall, anxious (d = 0.50) and depressive symptoms (d = 0.44) were higher in caregivers of children with asthma compared with caregivers of healthy children. Age, site of recruitment, and whether the asthma diagnosis was medically confirmed were included as potential moderators. The relationship between parental psychopathology and asthma was stronger in those with medically confirmed asthma and participants recruited from clinical settings. Other moderators were not significant. Caregivers of children with asthma appear to have greater anxious and depressive symptoms than caregivers of healthy children, but the reasons are unclear. More research that investigates modifiable factors that may moderate this association is urgently needed. © The Author 2015.

The combination of fluticasone furoate and vilanterol trifenatate in the management of asthma: clinical trial evidence and experience

PubMed Central

Albertson, Timothy E.; Richards, John R.; Zeki, Amir A.

2015-01-01

The treatment of persistent asthma has been aided by the recent approval of new medications. The combined inhaled corticosteroid (ICS)/long-acting β2 agonist (LABA) powder inhaler fluticasone furoate (FF)/vilanterol trifenatate (VI) is one of these new agents, which was recently approved as a maintenance therapy for persistent asthma. This once-daily ICS/LABA inhaler has previously been approved and used in chronic obstructive pulmonary disease as a maintenance therapy. Both FF and VI individually have been shown to have efficacy in the treatment of persistent asthma; the combination of FF/VI at the dose of 100/25 μg daily improves trough peak expiratory flows and forced expiratory volume in 1 s. It also reduces the frequency of asthma exacerbations in patients with persistent asthma. The once-daily dosing is well tolerated, with limited clinically significant adverse events; the once-daily inhaled dosing regimen should also improve medication adherence. The data supporting the use of the FF/VI inhaler in persistent asthma are reviewed. The dry powder inhaler of FF/VI (100/25 μg) is an effective and well tolerated once-daily maintenance treatment for patients with persistent asthma. PMID:26668137

Beliefs Regarding Asthma Management Relating to Asthma Action Plans (AAPs) of African American Caregivers Residing in Newark, New Jersey Public Housing Communities.

PubMed

Wagner, Frank; Steefel, Lorraine

The purpose of this study was to explore the beliefs regarding asthma management and Asthma Action Plans (AAPs) of African American caregivers residing in three New Jersey public housing communities in Newark, New Jersey. A qualitative methods design was accomplished using semi-structured interviews with a purposive sample of nine African American caregivers of children with asthma. Information was coded using N'VIVO™; the textual analysis combined codes into categories, which were then assembled into themes. Self-determination was found to be a fundamental goal of asthma management; however, three themes emerged as barriers and facilitators to this goal: challenges in the urban environment, preference of familial methods, and access to medical care. Findings from this study regarding minority caregivers' beliefs regarding difficulty navigating the health care system coupled with insurance instability, leading to use of Emergency Departments, are consistent with past research. Although caregivers expressed belief in use of prescribed medications as indicated on AAPs, familial methods, found to provide a sense of control over asthma, were preferred.

A Case of Occupational Asthma in a Plastic Injection Process Worker

PubMed Central

2013-01-01

Objectives We report a case of death due to asthma attack in a plastic injection process worker with a history of asthma. Methods To assess task relevance, personal history including occupational history and medical records were reviewed. Samples of the substances utilized in the injection process were collected by visiting the patient’s workplace. The work environment with the actual process was reproduced in the laboratory, and the released substances were evaluated. Results The medical records confirmed that the patient’s conventional asthma was in remission. The analysis of the resins discharged from the injection process simulation revealed styrene, which causes occupational asthma, and benzenepropanoic acid, 3,5-bis(1,1-dimethylethyl)-4-hydroxy-, and octadecyl ester. Even though it was not the case in the present study, various harmful substances capable of inducing asthma such as formaldehyde, acrolein, and acetic acid are released during resin processing. Conclusion A worker was likely to occur occupational asthma as a result of the exposure to the harmful substances generated during the plastic injection process. PMID:24472161

Conceptual framework of the Controlling Asthma in American Cities Project.

Herman, Elizabeth Jane

2011-02-01

The Controlling Asthma in American Cities Project (CAACP) was designed to improve the control of asthma in inner-city populations of children with a disparate burden of symptoms and adverse outcomes. As with many chronic diseases, asthma is the manifestation of multiple biologic, environmental, and social determinants. In addition to appropriate medical management, individuals with asthma must have logistical, financial, and cultural access to environments that allow avoidance of asthma triggers and encourage good asthma management practices. In recognition of this complexity, the CAACP required the seven project sites to coordinate and synchronize multiple interventions (education, healthcare access, medical management, trigger reduction) at multiple levels (individual, home, school, community, and policy) through the collaboration of relevant groups, institutions, and individuals. This paper describes the "program theory" of the CAACP project-the assumptions about how the project worked, how the components were linked, and what outcomes were anticipated. It relates the subsequent papers in the supplement to the program theory and describes how the papers can inform and guide other community-based interventions, and advance the translation of scientific knowledge to effective interventions in communities of need.

An association between salmeterol, a long-acting β(2)-agonist (LABA), use and rare serious asthma events or asthma mortality was observed in two large clinical trials. This has resulted in heightened scrutiny of LABAs and comprehensive reviews by regulatory agencies. The aim of this retrospective observational cohort study was to better characterize salmeterol medication use patterns in the UK. We describe asthma prescription patterns in a cohort of patients (n =17,745) in the General Practice Research Database who initiated treatment with salmeterol-containing prescriptions between 2003 and 2006, including salmeterol and salmeterol/fluticasone propionate in a single device. Prescriptions patterns by medication class, including concurrent prescription of salmeterol with inhaled corticosteroids (ICS), were described using 6-month intervals in the 1-year period before and after the salmeterol-containing index prescription. In the 0- to 6-month and 7- to 12-month periods prior to initiation of the salmeterol-containing prescription, the cohort experienced worsening of asthma, measured by an increase in the proportion of patients with prescriptions for short-acting β-agonists [SABA] (73-89%), ICS (70-81%) and systemic corticosteroids (14-28%). Nearly all patients prescribed salmeterol were concurrently prescribed ICS (≥95% within 90 days). In the 12 months following initiation of the salmeterol-containing prescription, a decrease in asthma prescriptions was observed. These results support the appropriate prescribing of salmeterol-containing medications, as per recommendations in asthma treatment guidelines in the UK. Salmeterol was consistently prescribed as an add-on asthma-controller with an ICS for most patients, and was associated with improvements in asthma control, as indicated by decreases in SABA and systemic corticosteroid prescriptions following salmeterol introduction.

Noninvasive ventilation for acute exacerbations of asthma: A systematic review of the literature.

PubMed

2017-11-01

Asthma is a chronic disease characterised by reversible airway obstruction caused by bronchospasm, mucous and oedema. People with asthma commonly experience acute exacerbations of their disease requiring hospitalisation and subsequent utilisation of economic and healthcare resources. Noninvasive ventilation has been suggested as a treatment for acute exacerbations of asthma due to its ability to provide airway stenting, optimal oxygen delivery and decreased work of breathing. This paper is a systematic review of the available published research focused on the use of noninvasive ventilation for the treatment of acute exacerbations of asthma to determine if this treatment provides better outcomes for patients compared to standard medical therapy. Database searches were conducted using EBSCOhost, MEDLINE and PubMed. Search terms used were combinations of 'noninvasive ventilation', 'BiPAP', 'CPAP', 'wheez*' and 'asthma'. Articles were included if they were research papers focused on adult patients with asthma and a treatment of noninvasive ventilation, and were published in full text in English. Included articles were reviewed using the National Health and Medical Research Council (Australia) evidence hierarchy and quality appraisal tools. There were 492 articles identified from the database searches. After application of inclusion/exclusion criteria 13 articles were included in the systematic review. Studies varied significantly in design, endpoints and outcomes. There was a trend in better outcomes for patients with acute asthma who were treated with noninvasive ventilation compared to standard medical therapy, however, the variability of the studies meant that no conclusive recommendations could be made. More research is required before noninvasive ventilation can be conclusively recommended for the treatment of acute exacerbations of asthma.

Baker's asthma, though having been recognized and studied since long time, still stays one of the most common causes of occupational asthma. Moreover, our understanding of the causative agents, the pathophysiological mnechanisms, the usefulness of medical surveillance, the proper treatment and prevention of the disease is still scanty. This is due to either to its complex pathogenesis or to possible confoundings, besides the still inadequate quality and standardization of the tools available as far as the allergologic diagnosis is concerned. Proper medical surveillance, validated causal therapies, efficient primary prevention are still uncertain. Change of employment or relocation is often impossible, particularly among artisan workers. Various evidences have been critically revised and summarized.

The house dust mite is the most important environmental allergen implicated in the aetiology of childhood asthma in the UK. Dust mite barrier bedding is relatively inexpensive, convenient to use, and of proven effectiveness in reducing mattress house dust mite load, but no studies have evaluated its clinical effectiveness in the control of childhood asthma when dispensed in primary care. We therefore aimed to evaluate the effectiveness of house dust mite barrier bedding in children with asthma treated in primary care. Pragmatic, randomised, double-blind, placebo controlled trial conducted in eight family practices in England. Forty-seven children aged 5 to 14 years with confirmed house dust mite sensitive asthma were randomised to receive six months treatment with either house dust mite barrier or placebo bedding. Peak expiratory flow was the main outcome measure of interest; secondary outcome measures included asthma symptom scores and asthma medication usage. No difference was noted in mean monthly peak expiratory flow, asthma symptom score, medication usage or asthma consultations, between children who received active bedding and those who received placebo bedding. Treating house dust mite sensitive asthmatic children in primary care with house dust mite barrier bedding for six months failed to improve peak expiratory flow. Results strongly suggest that the intervention made no impact upon other clinical features of asthma.

The relationship between sex hormones and asthma has been evaluated in several studies. The aim of this review article was to investigate the association between asthma and female sex hormones, under different conditions (premenstrual asthma, use of oral contraceptives, menopause, hormone replacement therapy and pregnancy). Narrative review of the medical literature, Universidade Federal do Tocantins (UFT) and Universidade Federal de São Paulo (Unifesp). We searched the CAPES journal portal, a Brazilian platform that provides access to articles in the MEDLINE, PubMed, SciELO, and LILACS databases. The following keywords were used based on Medical Subject Headings: asthma, sex hormones, women and use of oral contraceptives. The associations between sex hormones and asthma remain obscure. In adults, asthma is more common in women than in men. In addition, mortality due to asthma is significantly higher among females. The immune system is influenced by sex hormones: either because progesterone stimulates progesterone-induced blocking factor and Th2 cytokines or because contraceptives derived from progesterone and estrogen stimulate the transcription factor GATA-3. The associations between asthma and female sex hormones remain obscure. We speculate that estrogen fluctuations are responsible for asthma exacerbations that occur in women. Because of the anti-inflammatory action of estrogen, it decreases TNF-α production, interferon-γ expression and NK cell activity. We suggest that further studies that highlight the underlying physiopathological mechanisms contributing towards these interactions should be conducted.

Poor adherence to recommended preventive asthma medications is common, leading to preventable morbidity. We developed the School-Based Telemedicine Enhanced Asthma Management (SB-TEAM) program to build on school-based supervised therapy programs by incorporating telemedicine at school to overcome barriers to preventive asthma care. To evaluate the effect of the SB-TEAM program on asthma morbidity among urban children with persistent asthma. In this randomized clinical trial, children with persistent asthma aged 3 to 10 years in the Rochester City School District in Rochester, New York, were stratified by preventive medication use at baseline and randomly assigned to the SB-TEAM program or enhanced usual care for 1 school year. Participants were enrolled at the beginning of the school year (2012-2016), and outcomes were assessed through the end of the school year. Data were analyzed between May 2017 and November 2017 using multivariable modified intention-to-treat analyses. Supervised administration of preventive asthma medication at school as well as 3 school-based telemedicine visits to ensure appropriate assessment, preventive medication prescription, and follow-up care. The school site component of the telemedicine visit was completed by telemedicine assistants, who obtained history and examination data. These data were stored in a secure virtual waiting room and then viewed by the primary care clinician, who completed the assessment and communicated with caregivers via videoconference or telephone. Preventive medication prescriptions were sent to pharmacies that deliver to schools for supervised daily administration. The primary outcome was the mean number of symptom-free days per 2 weeks, assessed by bimonthly blinded interviews. Of the 400 enrolled children, 247 (61.8%) were male and 230 (57.5%) were African American, and the mean (SD) age was 7.8 (1.7) years. Demographic characteristics and asthma severity in the 2 groups were similar at baseline. Among children in the SB-TEAM group, 196 (98.0%) had 1 or more telemedicine visits, and 165 (82.5%) received supervised therapy through school. We found that children in the SB-TEAM group had more symptom-free days per 2 weeks postintervention compared with children in the enhanced usual care group (11.6 vs 10.97; difference, 0.69; 95% CI, 0.15-1.22; P = .01), with the largest difference observed at the final follow-up (difference, 0.85; 95% CI, 0.10-1.59). In addition, children in the SB-TEAM group were less likely to have an emergency department visit or hospitalization for asthma (7% vs 15%; odds ratio, 0.52; 95% CI, 0.32-0.84). The SB-TEAM intervention significantly improved symptoms and reduced health care utilization among urban children with persistent asthma. This program could serve as a model for sustainable asthma care among school-aged children. clinicaltrials.gov Identifier: NCT01650844.

Socio-economic disadvantage, quality of medical care and admission for acute severe asthma.

PubMed

Kolbe, J; Vamos, M; Fergusson, W

1997-06-01

In asthma, socio-economic and health care factors may operate by a number of mechanisms to influence asthma morbidity and mortality. To determine the quality of medical care including the patient perception of the doctor-patient relationship, and the level of socio-economic disadvantage in patients admitted to hospital with acute severe asthma. One hundred and thirty-eight patients (15-50 years) admitted to hospital (general ward or intensive care unit) with acute asthma were prospectively assessed using a number of previously validated instruments. The initial subjects had severe asthma on admission (pH = 7.3 +/- 0.2, PaCO2 = 7.1 +/- 5.0 kPa, n = 90) but short hospital stay (3.7 +/- 2.6 days). Although having high morbidity (40% had hospital admission in the last year and 60% had moderate/severe interference with sleep and/or ability to exercise), they had indicators of good ongoing medical care (96% had a regular GP, 80% were prescribed inhaled steroids, 84% had a peak flow meter, GP measured peak flow routinely in 80%, 52% had a written crisis plan and 44% had a supply of steroids at home). However, they were severely economically disadvantaged (53% had experienced financial difficulties in the last year, and for 35% of households the only income was a social security benefit). In the last year 39% had delayed or put off GP visit because of cost. Management of the index attack was compromised by concern about medical costs in 16% and time off work in 20%. Patients admitted to hospital with acute asthma have evidence of good quality on-going medical care, but are economically disadvantaged. If issues such as financial barriers to health care are not acknowledged and addressed, the health care services for asthmatics will not be effectively utilised and the current reductions in morbidity and mortality may not be maintained.

Applied environmental strategies for asthma control are often expensive, but may save longer-term healthcare costs. Whether these savings outweigh additional costs of implementing these strategies is uncertain. We conducted a systematic review to estimate the expenditures and savings of environmental interventions for asthma in the state of Maryland. Direct costs included hospitalizations, emergency room, and clinic visits. Indirect expenditures included costs of lost work productivity and travel incurred during the usage of healthcare services. We used decision analysis, assuming a hypothetical cohort of the approximated 49,290 pediatric individuals in Maryland with persistent asthma, to compare costs and benefits of environmental asthma interventions against the standard of care (no intervention) from the societal perspective. Three interventions among nine articles met the inclusion criteria for the systematic review: 1) environmental education using medical professionals; 2) education using non-medical personnel; and 3) multi-component strategy involving education with non-medical personnel, allergen-impermeable covers, and pest management. All interventions were found to be cost-saving relative to the standard of care. Home environmental education using non-medical professionals yielded the highest net savings of $14.1 million (95% simulation interval (SI): $-.283 million, $19.4 million), while the multi-component intervention resulted in the lowest net savings of $8.1 million (95% SI: $-4.9 million, $15.9 million). All strategies were most sensitive to the baseline number of hospitalizations in those not receiving targeted interventions for asthma. Limited environmental reduction strategies for asthma are likely to be cost-saving to the healthcare system in Maryland and should be considered for broader scale-up in other economically similar settings.

Gastro-oesophageal reflux disease (GORD) symptoms are common in asthma and have been extensively studied, but less so in the Asian continent. Reflux-associated respiratory symptoms (RARS) have, in contrast, been little-studied globally. We report the prevalence of GORD symptoms and RARS in adult asthmatics, and their association with asthma severity and medication use. A cross-sectional analytical study. A validated interviewer-administered GORD scale was used to assess frequency and severity of seven GORD symptoms. Subjects were consecutive asthmatics attending medical clinics. Controls were matched subjects without respiratory symptoms. The mean (SD) composite GORD symptom score of asthmatics was significantly higher than controls (21.8 (17.2) versus 12.0 (7.6); P < 0.001) as was frequency of each symptom and RARS. Prevalence of GORD symptoms in asthmatics was 59.4% (95% CI, 59.1%-59.6%) versus 28.5% in controls (95% CI, 29.0% - 29.4%). 36% of asthmatics experienced respiratory symptoms in association with both typical and atypical GORD symptoms, compared to 10% of controls (P < 0.001). An asthmatic had a 3.5 times higher risk of experiencing a GORD symptom after adjusting for confounders (OR 3.5; 95% CI 2.5-5.3). Severity of asthma had a strong dose-response relationship with GORD symptoms. Asthma medication use did not significantly influence the presence of GORD symptoms. GORD symptoms and RARS were more prevalent in a cohort of Sri Lankan adult asthmatics compared to non-asthmatics. Increased prevalence of RARS is associated with both typical and atypical symptoms of GORD. Asthma disease and its severity, but not asthma medication, appear to influence presence of GORD symptoms.

This study aimed to evaluate the impact of information technology tools on the outcomes of children with asthma in the medical home. A registry was established for children aged 4 to 18 years with an ICD-9 code for asthma. Changes to the electronic health record included modifications to notes, care plans, and orders. A retrospective analysis of emergency department and in-patient utilization for a cohort of patients was conducted from July 2009 through June 2013. Of the study population (n = 1217), 65% had a classification of asthma severity and 63% were risk-stratified. Seventy percent had a control assessment at least once. Care plan use increased from 5% to 22% and enrollment in care coordination increased from 0.1% to 4%. After 3 years, there was a reduction of emergency department and inpatient admissions for asthma (P < .05 and P < .005, respectively). The implementation of information technology tools was associated with improved asthma outcomes. © The Author(s) 2015.

The Asthma Kiosk: A Patient-centered Technology for Collaborative Decision Support in the Emergency Department

2004-01-01

The authors report on the development and evaluation of a novel patient-centered technology that promotes capture of critical information necessary to drive guideline-based care for pediatric asthma. The design of this application, the asthma kiosk, addresses five critical issues for patient-centered technology that promotes guideline-based care: (1) a front-end mechanism for patient-driven data capture, (2) neutrality regarding patients' medical expertise and technical backgrounds, (3) granular capture of medication data directly from the patient, (4) formal algorithms linking patient-level semantics and asthma guidelines, and (5) output to both patients and clinical providers regarding best practice. The formative evaluation of the asthma kiosk demonstrates its ability to capture patient-specific data during real-time care in the emergency department (ED) with a mean completion time of 11 minutes. The asthma kiosk successfully links parents' data to guideline recommendations and identifies data critical to health improvements for asthmatic children that otherwise remains undocumented during ED-based care.

To explore utilisation patterns of asthma medication before, during and after pregnancy as recorded in seven European population-based databases. A descriptive drug utilisation study. 7 electronic healthcare databases in Denmark, Norway, the Netherlands, Italy (Emilia Romagna and Tuscany), Wales, and the Clinical Practice Research Datalink representing the rest of the UK. All women with a pregnancy ending in a delivery that started and ended between 2004 and 2010, who had been present in the database for the year before, throughout and the year following pregnancy. The percentage of deliveries where the woman received an asthma medicine prescription, based on prescriptions issued (UK) or dispensed (non-UK), during the year before, throughout or during the year following pregnancy. Asthma medicine prescribing patterns were described for 3-month time periods and the choice of asthma medicine and changes in prescribing over the study period were evaluated in each database. In total, 1,165,435 deliveries were identified. The prevalence of asthma medication prescribing during pregnancy was highest in the UK and Wales databases (9.4% (CI95 9.3% to 9.6%) and 9.4% (CI95 9.1% to 9.6%), respectively) and lowest in the Norwegian database (3.7% (CI95 3.7% to 3.8%)). In the year before pregnancy, the prevalence of asthma medication prescribing remained constant in all regions. Prescribing levels peaked during the second trimester of pregnancy and were at their lowest during the 3-month period following delivery. A decline was observed, in all regions except the UK, in the prescribing of long-acting β-2-agonists during pregnancy. During the 7-year study period, there were only small changes in prescribing patterns. Differences were found in the prevalence of prescribing of asthma medications during and surrounding pregnancy in Europe. Inhaled β-2 agonists and inhaled corticosteroids were, however, the most popular therapeutic regimens in all databases. Published by the BMJ Publishing Group Limited.

To investigate the burden of asthma in a young adult population in urban areas of Argentina. A nationwide telephone survey in subjects aged 20-44 years was performed in urban areas in Argentina. The European Community Respiratory Health Survey questionnaire was used. Asthma was defined as an exacerbation in the last year or use of asthma medications. In total, 1,521 subjects responded (62.4% females, mean age 33 years), of whom 91 were classified as asthmatics (5.9%, 95% CI 4.7-7.1). Prevalence adjusted for age, sex and education level was 6.4% (95% CI 5.1-7.7). Wheezing was reported by 13.9% (95% CI 15.6-12.2) and a diagnosis of asthma by 9.5% (95% CI 8.0-11.0). Among individuals with a diagnosis of asthma (n=154), 71.3% had undergone spirometry. Among those treated (n=77), 51.9% used medications daily and 46.8% as a rescue measure. Of those reporting an exacerbation in the last year (n=60), 55% had attended an emergency department and 23% were admitted. Asthma was associated with rhinitis (OR 11.1, 95% CI 6.2-19.9) and family history (OR 3.6, 95% CI 2.3-5.5). Asthma prevalence in young adults in Argentina is similar to Europe. Although attacks and admissions were common, regular use of medications was reported by half of those treated. These results may be useful for other Latin American countries. Copyright © 2017 SEPAR.

2018-01-16

Recent statistics show a relatively high prevalence of asthma among Moroccan children and a weak control over their symptoms. To our knowledge, no research has been carried out to document adherence to the controller treatment in this population. This study aims 1) to assess the extent of children's nonadherence to the controller treatment of asthma in an urban region of Morocco as reported by a family caregiver, and 2) to identify the associated factors. We conducted a cross-sectional study among caregivers of asthmatic children (2-12 years old) in different health and education facilities of Casablanca-Settat. We administered face-to-face questionnaires incorporating validated instruments (Medication Adherence Rating Scale-Asthma (MARS-A), Beliefs about Medicines Questionnaire (BMQ), Asthma Knowledge Questionnaire). Univariate and multivariate log-binomial regressions evaluating the association between several factors and reported nonadherence were performed (prevalence ratios (PR) and 95% confidence intervals (CI)). Through two public hospitals, three private medical clinics, and one private school, 103 caregivers were recruited. Low adherence to the controller treatment of asthma was reported by 48% of the caregivers (MARS-A <45). In the multivariate model, caregivers with the lowest level of knowledge about asthma were almost three times more likely to report low adherence compared to caregivers with the highest level (PR = 2.93; 95% CI: 1.14-7.52). This study highlights the finding that low adherence is widespread in this context and also the importance of targeting caregivers' knowledge of asthma for interventions.

Molecular and cellular mechanisms underlying the therapeutic effects of budesonide in asthma.

Inhaled glucocorticoids are the mainstay of asthma treatment. Indeed, such therapeutic agents effectively interfere with many pathogenic circuits underpinning asthma. Among these drugs, during the last decades budesonide has been probably the most used molecule in both experimental studies and clinical practice. Therefore, a large body of evidence clearly shows that budesonide, either alone or in combination with long-acting bronchodilators, provides a successful control of asthma in many patients ranging throughout the overall spectrum of disease severity. These excellent therapeutic properties of budesonide basically depend on its molecular mechanisms of action, capable of inhibiting within the airways the activity of multiple immune-inflammatory and structural cells involved in asthma pathobiology.

Asthma still has high morbidity and cost despite all advances in pathogenesis, diagnosis and treatment. Although asthma can be controlled with proper diagnosis and treatment, the low rates of control in our country and in the world can not be attributed to the variable course of the disease and patients' psycho-social behaviours for chronic disease. In this context, Turkish Thoracic Society (TTS) has decided to update Asthma Diagnosis and Management Guide latest published in 2000. National data were collected, compiled and prepared by authors, and final form given by the TTS Asthma and Allergy Study Group, after presenting to consultant individuals and institutions. In June 2009, the National Asthma Management and Prevention Guideline were published in Turkish. In this paper, we aimed to present the national guide in English with its basics and individual differences.

In the Study to Investigate Real Life Effectiveness of Symbicort Maintenance and Reliever Therapy in Asthma Patients Across Asia, the effectiveness of single-inhaler budesonide/formoterol maintenance and reliever therapy was evaluated in patients with poorly controlled asthma. To study the effects of this therapy on a Chinese patient subgroup. In this 12-week, multicenter, open-label therapeutic phase IV study, patients with partially controlled or uncontrolled asthma were switched from their usual asthma treatment to budesonide/formoterol (160/4.5 μg, one inhalation twice daily and as needed) after a 2-week run-in period. Primary and secondary objectives of the study, asthma control and quality of life were assessed by using the five-item Asthma Control Questionnaire and the Standardized Asthma Quality of Life Questionnaire. Asthma symptom scores, study medication use, asthma control and/or symptom-free days, and the number of asthma-related nighttime awakenings were also monitored. In total, 478 Chinese patients were enrolled and 407 patients initiated treatment. The patients displayed a significant improvement in mean (standard deviation) five-item Asthma Control Questionnaire (-0.58 ± 0.86; p < 0.0001) and Standardized Asthma Quality of Life Questionnaire (0.69 ± 0.79; p < 0.0001) scores versus the run-in period. Mean (standard deviation) asthma symptom scores were significantly reduced compared with run-in (-0.30 ± 0.55 daytime, -0.31 ± 0.56 nighttime; p < 0.0001 for both), as was as-needed study medication use (-0.24 ± 1.16 daytime, -0.28 ± 0.97 nighttime; p < 0.0001 for both). Patients who received previous treatment with salmeterol/fluticasone propionate also showed improvement in asthma control. In China, asthma control in Chinese patients whose asthma was not fully controlled with previous standard therapy improved during 12 weeks of treatment with budesonide/formoterol maintenance and reliever therapy. Quality of life was improved, and treatment was well tolerated. (Clinical Trials identifier NCT00939341).

Exhaled nitric oxide levels to guide treatment for adults with asthma.

Asthma guidelines aim to guide health practitioners to optimise treatment for patients so as to minimise symptoms, improve or maintain good lung function, and prevent acute exacerbations or flare-ups. The principle of asthma guidelines is based on a step-up or step-down regimen of asthma medications to maximise good health outcomes using minimum medications. Asthma maintenance therapies reduce airway inflammation that is usually eosinophilic. Tailoring asthma medications in accordance with airway eosinophilic levels may improve asthma outcomes such as indices of control or reduce exacerbations or both. Fractional exhaled nitric oxide (FeNO) is a marker of eosinophilic inflammation, and as it is easy to measure, has an advantage over other measurements of eosinophilic inflammation (for example sputum eosinophils). To evaluate the efficacy of tailoring asthma interventions based on exhaled nitric oxide (FeNO), in comparison to not using FeNO, that is management based on clinical symptoms (with or without spirometry/peak flow) or asthma guidelines or both, for asthma-related outcomes in adults. We searched the Cochrane Airways Group Specialised Register of Trials, the Cochrane Central Register of Controlled Trials (CENTRAL), MEDLINE, EMBASE, and reference lists of articles. The last searches were undertaken in June 2016. All randomised controlled trials (RCTs) comparing adjustment of asthma medications based on exhaled nitric oxide levels compared to not using FeNO, that is management based on clinical symptoms (with or without spirometry/peak flow) or asthma guidelines or both. We reviewed results of searches against predetermined criteria for inclusion. We independently selected relevant studies in duplicate. Two review authors independently assessed trial quality and extracted data. We contacted study authors for further information, receiving responses from four. We included seven adult studies; these studies differed in a variety of ways including definition of asthma exacerbations, FeNO cutoff levels used (15 to 35 ppb), the way in which FeNO was used to adjust therapy, and duration of study (4 to 12 months). Of 1700 randomised participants, 1546 completed the trials. The mean ages of the participants ranged from 28 to 54 years old. The inclusion criteria for the participants in each study varied, but all had a diagnosis of asthma and required asthma medications. In the meta-analysis, there was a significant difference in the primary outcome of asthma exacerbations between the groups, favouring the FeNO group. The number of people having one or more asthma exacerbations was significantly lower in the FeNO group compared to the control group (odds ratio (OR) 0.60, 95% confidence interval (CI) 0.43 to 0.84). The number needed to treat to benefit (NNTB) over 52 weeks was 12 (95% CI 8 to 32). Those in the FeNO group were also significantly more likely to have a lower exacerbation rate than the controls (rate ratio 0.59, 95% CI 0.45 to 0.77). However, we did not find a difference between the groups for exacerbations requiring hospitalisation (OR 0.14, 95% CI 0.01 to 2.67) or rescue oral corticosteroids (OR 0.86, 95% CI 0.50 to 1.48). There was also no significant difference between groups for any of the secondary outcomes (FEV 1 , FeNO levels, symptoms scores, or inhaled corticosteroid doses at final visit).We considered three included studies that had inadequate blinding to have a high risk of bias. However, when these studies were excluded from the meta-analysis, the difference between the groups for the primary outcomes (exacerbations) remained statistically significant. The GRADE quality of the evidence ranged from moderate (for the outcome 'exacerbations') to very low (for the outcome 'inhaled corticosteroid dose at final visit') based on the lack of blinding and statistical heterogeneity. Six of the seven studies were industry supported, but the company had no role in the study design or data analyses. With new studies included since the last version of this review, which included adults and children, this updated meta-analysis in adults with asthma showed that tailoring asthma medications based on FeNO levels (compared with primarily on clinical symptoms) decreased the frequency of asthma exacerbations but did not impact on day-to-day clinical symptoms, end-of-study FeNO levels, or inhaled corticosteroid dose. Thus, the universal use of FeNO to help guide therapy in adults with asthma cannot be advocated. As the main benefit shown in the studies in this review was a reduction in asthma exacerbations, the intervention may be most useful in adults who have frequent exacerbations. Further RCTs encompassing different asthma severity, ethnic groups in less affluent settings, and taking into account different FeNO cutoffs are required.

Little data in the literature exist concerning patients with certain underlying medical conditions who receive allergen subcutaneous immunotherapy (SCIT). To survey allergists' experience with SCIT in patients with medical conditions considered to impose an elevated risk for untoward outcomes. A Web-based survey was conducted among members of the American Academy of Allergy, Asthma & Immunology to query about their experience with SCIT in patients with certain medical conditions. There were 1085 replies (21% response), of whom, 86% were U.S. based, 51% were suburban, 31% were academic, 42% were medium-sized practices, and 54% had >15 years' experience. In responders' opinion, SCIT was "contraindicated" in patients with the following: acquired immune deficiency syndrome (AIDS) (48%), cancer (and still receiving active treatment) (33%), severe asthma (32%), and a history of transplantation (30%). Even so, survey responders collectively gave SCIT to >2400 patients for each of these conditions: severe asthma, coronary artery disease, cancer in remission, and autoimmune disorders; and to ≥5400 patients with hypertension and ≥4100 women who became pregnant. The experience of colleagues with these patients rarely resulted in major problems (i.e., activation of underlying disease, systemic reactions to SCIT, or SCIT discontinuation), with the exception of severe asthma (12.5%), initiation of SCIT during pregnancy (5.4%), and AIDS (4.2%). For most other conditions, it was ≤1.5% (e.g., continue during pregnancy, cancer in remission, history of transplantation, positive human immunodeficiency virus and no AIDS). According to the experience of a large group of practicing allergists, the American Academy of Allergy, Asthma & Immunology members, few medical conditions seemed to pose an elevated risk for untoward outcomes from SCIT. Because these are survey results, prospective research might yield even more solid data.

To assess changes in knowledge, attitudes, and intentions among childcare workers before and after an asthma-management-education session. Between May and August 2004 five asthma-education sessions were provided for childcare workers from Sonoma County, California. A total of 71 childcare workers came to the sessions. Before and after each session we assessed the participants' knowledge, attitudes, and intentions about asthma. Participant knowledge of asthma causes (eg, air quality, common cold) and interventions (eg, bronchodilators), asthma trigger control plans, ability to identify a child who needs medical attention for asthma, and comfort level with caring for a child with asthma increased significantly. Their knowledge about asthma triggers, early warning signs, and asthma control plans was high before and after the asthma education intervention. Their stated intentions to utilize their asthma knowledge were high before and after the training, which may indicate willingness to implement knowledge and attitude change. Asthma education can improve childcare workers' knowledge about asthma-control strategies and attitudes toward asthma interventions.

To study the efficacy of community management model of bronchial asthma in children. Through community outreach and clinic, 120 cases of children with asthma were enrolled from the 11 000 children aged 0 to 14 in Zhanlanlu area, and a community management model of asthma was established according to the Global Initiative for Asthma requirements combined with the actual situation of the community, both physicians and patients participated in case identification, file creation, and long-term standardized management. Through repeated medical education, the telephone hotline and interactive network of asthma among physicians, children and parents, a physician-patient relationship was established. The data of standardized medication, scheduled re-visit to the hospital, frequency of asthma attacks, antibiotic use, medical expenses, the loss of parents work hours etc. before and after the implementation of community management model were analyzed and compared. After implementation of community management model, the use of systemic corticosteroids (19.4%), oral medication (31.6%) was significantly lower than those before implementation (68.3% and 90.0%) (χ(2) = 51.9, 41.1, P < 0.01), use of inhaled corticosteroids (76.5%) and oral leukotriene receptor antagonist (79.6%) was significantly higher compared with control and before management level (10.0%), χ(2) = 106.0, P < 0.01. The days of attacks of asthma (4.6 ± 2.3), the use of antibiotics (16.2 ± 6.1), (5.7 ± 2.9) and the cost of treatment significantly decreased. In 16 cases (13.3%) two-way referral was applied. In this study, the dropout rate was 18.3%, by telephone and network supervision of lost cases, re-education, made some children return to management, eventually the dropout rate was 9.2%. Enrollment of children with bronchial asthma into community management model made the children adhere to the management regularly and a standardized management was achieved.

It has been suggested that children that are exposed to a stressful environment at home have an increased susceptibility for air pollution-related asthma. The aim here was to investigate the association between air pollution exposure and asthma, and effect modification by mental health and by socio-economic status (as markers of a stressful environment). All individuals under 18 years of age in four Swedish counties during 2007 to 2010 (1.2 million people) were included. The outcome was defined as dispensing at least two asthma medications during follow up. We linked data on NO₂ from an empirical land use regression to data from national registers on outcome and potential confounders. Data was analyzed with logistic regression. There was an odds ratio (OR) of 1.02 (95% Confidence Interval (CI: 1.01-1.03) for asthma associated with a 10 µg·m -3 increase in NO₂. The association only seemed to be present in areas where NO₂ was higher than 15 µg·m -3 with an OR of 1.09 (95% CI: 1.07-1.12), and the association seemed stronger in children with parents with a high education, OR = 1.05 (95% CI: 1.02-1.09) and OR = 1.04 (95% CI: 1.01-1.07) in children to mothers and father with a high education, respectively. The association did not seem to depend on medication history of psychiatric disorders. There was weak evidence for the association between air pollution and asthma to be stronger in neighborhoods with higher education levels. In conclusion, air pollution was associated with dispensed asthma medications, especially in areas with comparatively higher levels of air pollution, and in children to parents with high education. We did not observe support for our hypothesis that stressors linked to socio-economy or mental health problems would increase susceptibility to the effects of air pollution on the development of asthma.

The preferences of parents and children with asthma influence their ability to manage a child's asthma and achieve good control. Potential differences between parents and adolescents with respect to specific parameters of asthma control are not considered in clinical asthma guidelines. The objective was to measure and compare the preferences of parents and adolescents with asthma with regard to asthma control parameters using best worst scaling (BWS). Fifty-two parents of children with asthma and 44 adolescents with asthma participated in a BWS study to quantify preferences regarding night-time symptoms, wheezing/chest tightening, changes in asthma medications, emergency visits and physical activity limitations. Conditional logit regression was used to determine each group's utility for each level of each asthma control parameter. Parents displayed the strongest positive preference for the absence of night-time symptoms (β = 2.09, p < 0.00001) and the strongest negative preference for 10 emergency room visits per year (β = -2.15, p < 0.00001). Adolescents displayed the strongest positive preference for the absence of physical activity limitations (β = 2.17, p < 0.00001) and the strongest negative preference for ten physical activity limitations per month (β = -1.97). Both groups were least concerned with changes to medications. Parents and adolescents placed different weights on the importance of asthma control parameters and each group displayed unique preferences. Understanding the relative importance placed on each parameter by parents and adolescents is essential for designing effective patient-focused disease management plans.

The National Asthma Education and Prevention Program (NAEPP) and the American Thoracic Society provide guidelines stating that physicians should use spirometry in the diagnosis and management of asthma. The aim of this study was to evaluate the trends, over a 10-year period, in the utilization of spirometry in patients newly diagnosed with asthma. We hypothesized that spirometry use would increase in physicians who care for asthma patients, especially since 2007, when the revised NAEPP guidelines were published. This retrospective cohort analysis of spirometry use in subjects newly diagnosed with asthma used a privately insured adult population for the years 2002-2011. Our primary outcome of interest was spirometry performed within a year (± 365 days) of the initial date of asthma diagnosis. We also examined the type of asthma medications prescribed. In all, 134,208 patients were found to have a diagnosis of asthma. Only 47.6% had spirometry performed within 1 year of diagnosis. Younger patients, males, and those residing in the Northeast were more likely to receive spirometry. Spirometry use began to decline in 2007. Patients cared for by specialists were more likely to receive spirometry than those cared for by primary care physicians; 80.1% vs 23.3%, respectively. Lastly, even without spirometry, a significant portion of patients (78.3%) was prescribed asthma drugs. Our study suggests that spirometry is underutilized in newly diagnosed asthma patients. Moreover, the use of controller medications in those diagnosed with asthma without spirometry remains high. Copyright © 2015 Elsevier Inc. All rights reserved.

Low-income African American children have disproportionately higher asthma morbidity and mortality. Education alone may not address barriers to asthma management due to psychosocial stress. This study evaluated the efficacy of a home-based family intervention integrating asthma education and strategies to address stress using a community-based participatory research model. Children age 8 to 13 with poorly controlled asthma and their caregivers were recruited from an urban hospital and an asthma camp. Caregivers with elevated scores on a stress measure were enrolled. Forty-three families were randomized to the 4- to 6-session Home Based Family Intervention (HBFI) or the single session of Enhanced Treatment as Usual (ETAU). All families received an asthma action plan and dust mite covers; children performed spirometry and demonstrated MDI/spacer technique at each home visit. The HBFI addressed family-selected goals targeting asthma management and stressors. Asthma management, morbidity, family functioning, and caregiver stress were assessed at baseline, postintervention, and 6 months after the intervention. ED visits and hospitalizations were ascertained by medical record review for a year after intervention completion. Only one child (5%) in HBFI had an asthma-related hospitalization compared to 7 patients (35%) in ETAU in the year following intervention. Participants in both groups demonstrated improved asthma management and family functioning, and reduced ED visits, symptom days, missed school days, and caregiver stress, but there were no differential treatment effects. The results suggest that a home-based intervention addressing medical and psychosocial needs may prevent hospitalizations for children with poorly controlled asthma and caregivers under stress.

Many children with asthma do not have sufficient asthma control, which leads to increased healthcare costs and productivity loss of parents. One of the causative factors are adherence problems. Effective interventions improving medication adherence may therefore improve asthma control and reduce costs. A promising solution is sending real time text-messages via the mobile phone network, when a medicine is about to be forgotten. As the effect of real time text-messages in children with asthma is unknown, the primary aim of this study is to determine the effect of a Real Time Medication Monitoring system (RTMM) with text-messages on adherence to inhaled corticosteroids (ICS). The secondary objective is to study the effects of RTMM on asthma control, quality of life and cost-effectiveness of treatment. A multicenter, randomized controlled trial involving 220 children (4-11 years) using ICS for asthma. All children receive an RTMM-device for one year, which registers time and date of ICS doses. Children in the intervention group also receive tailored text-messages, sent only when a dose is at risk of omission. Primary outcome measure is the proportion of ICS dosages taken within the individually predefined time-interval. Secondary outcome measures include asthma control (monthly Asthma Control Tests), asthma exacerbations, healthcare use (collected from hospital records, patient reports and pharmacy record data), and disease-specific quality of life (PAQLQ questionnaire). Parental and children's acceptance of RTMM is evaluated with online focus groups and patient questionnaires. An economic evaluation is performed adopting a societal perspective, including relevant healthcare costs and parental productivity loss. Furthermore, a decision-analytic model is developed in which different levels of adherence are associated with clinical and financial outcomes. Also, sensitivity analyses are carried out on different price levels for RTMM. If RTMM with tailored text-message reminders proves to be effective, this technique can be used in daily practice, which would support children with suboptimal adherence in their asthma (self)management and in achieving better asthma control and better quality of life.

The effectiveness and practicality of the "Luftikids" (www.luftikids.de) structured, internet-based asthma refresher course was evaluated in a pilot study with 53 patients (ages 8 - 14 years). All patients had previously participated in either an inpatient or outpatient asthma education program. This prospective study examined the effect of a 4-week refresher course on parameters such as asthma symptoms (coughing, dyspnea), the number of unscheduled doctor's visits, use of on-demand medications, number of days absent from school, and asthma monitoring using the Asthma Control Questionnaire (ACQ) and lung function tests. The duration of program use and the number of logins was used to investigate acceptance of the game format. Data were collected at the beginning of the study and at 4 - 6 months after the end of the online refresher course. Significant changes were shown with regard to the decrease in intensity of asthma symptoms such as coughing (p = 0.001) and dyspnea (p = 0.007), reduction in the number of unscheduled doctor's visits (p = 0.005), the use of on-demand medications (4.0 ± 6.5 vs. 1.5 ± 4.9, p = < 0.002), and the number of days absent from school (1.2 ± 2.0 vs. 0.4 ± 1.2, p = 0.003). No changes in lung function parameters were observed. The "Luftikids" program was used for an average of 302.5 ± 210.9 minutes, and the number of logins was 14 ± 9. From their self-evaluations, the children and adolescents derived "much" to "very much" benefit. Only 7.5% reported no effect. Participation in the "Luftikids" internet-based asthma refresher course resulted in fewer asthma symptoms, a decrease in unscheduled doctor's visits, reduction in the use of on-demand medications, decrease in the number of days absent from school, and improved asthma knowledge. No effect in lung function could be demonstrated. The results support the effectiveness and good acceptance of an outpatient, internet-based asthma refresher course. Young asthma patients in particular can succeed with and be motivated by this form of refresher course. © Georg Thieme Verlag KG Stuttgart · New York.

Asthma is the most common pediatric illness in the United States, burdening low-income and minority families disproportionately and contributing to high health care costs. Clinic-based asthma education and telephone case management have had mixed results on asthma control, as have eHealth programs and online games. To test the effects of (1) CHESS+CM, a system for parents and children ages 4-12 years with poorly controlled asthma, on asthma control and medication adherence, and (2) competence, self-efficacy, and social support as mediators. CHESS+CM included a fully automated eHealth component (Comprehensive Health Enhancement Support System [CHESS]) plus monthly nurse case management (CM) via phone. CHESS, based on self-determination theory, was designed to improve competence, social support, and intrinsic motivation of parents and children. We identified eligible parent-child dyads from files of managed care organizations in Madison and Milwaukee, Wisconsin, USA, sent them recruitment letters, and randomly assigned them (unblinded) to a control group of treatment as usual plus asthma information or to CHESS+CM. Asthma control was measured by the Asthma Control Questionnaire (ACQ) and self-reported symptom-free days. Medication adherence was a composite of pharmacy refill data and medication taking. Social support, information competence, and self-efficacy were self-assessed in questionnaires. All data were collected at 0, 3, 6, 9, and 12 months. Asthma diaries kept during a 3-week run-in period before randomization provided baseline data. Of 305 parent-child dyads enrolled, 301 were randomly assigned, 153 to the control group and 148 to CHESS+CM. Most parents were female (283/301, 94%), African American (150/301, 49.8%), and had a low income as indicated by child's Medicaid status (154/301, 51.2%); 146 (48.5%) were single and 96 of 301 (31.9%) had a high school education or less. Completion rates were 127 of 153 control group dyads (83.0%) and 132 of 148 CHESS+CM group dyads (89.2%). CHESS+CM group children had significantly better asthma control on the ACQ (d = -0.31, 95% confidence limits [CL] -0.56, -0.06, P = .011), but not as measured by symptom-free days (d = 0.18, 95% CL -0.88, 1.60, P = 1.00). The composite adherence scores did not differ significantly between groups (d = 1.48%, 95% CL -8.15, 11.11, P = .76). Social support was a significant mediator for CHESS+CM's effect on asthma control (alpha = .200, P = .01; beta = .210, P = .03). Self-efficacy was not significant (alpha = .080, P = .14; beta = .476, P = .01); neither was information competence (alpha = .079, P = .09; beta = .063, P = .64). Integrating telephone case management with eHealth benefited pediatric asthma control, though not medication adherence. Improved methods of measuring medication adherence are needed. Social support appears to be more effective than information in improving pediatric asthma control.

The incidence and prevalence of asthma are increasing. One reason for this trend is the rise in adult-onset asthma, especially occupational asthma, which is 1 of the 2 forms of work-related asthma. Occupational asthma is defined as asthma caused by agents that are present exclusively in the workplace. The presence of pre-existing asthma does not rule out the possibility of developing occupational asthma. A distinction has traditionally been made between immunological occupational asthma (whether IgE-mediated or not) and nonimmunological occupational asthma caused by irritants, the most characteristic example of which is reactive airway dysfunction syndrome. The other form of work-related asthma is known as work-exacerbated asthma, which affects persons with pre-existing or concurrent asthma that is worsened by work-related factors. It is important to differentiate between the 2 entities because their treatment, prognosis, and medical and social repercussions can differ widely. In this review, we discuss diagnostic methods, treatment, and avoidance/nonavoidance of the antigen in immunological occupational asthma and work-exacerbated asthma. Key words: Specific inhalation challenge. Peak expiratory flow. Workplace. Irritants.

Asthma is the commonest pre-existing medical condition to complicate pregnancy. Acute severe asthma in pregnancy is rare, but poses difficult problems. In particular, the decision about when and where to deliver the fetus is complex, since maternal response to asthma treatment is unpredictable. We report the successful management of a parturient presenting with acute severe asthma at 37 weeks' gestation. The controversies involved and the importance of adopting a multi-disciplinary team approach to optimise maternal and neonatal outcomes are discussed.

The importance of balance between controller and reliever medications in asthma is recognized. However, to our knowledge, the extent to which real-world practice has caught up with evidence-based guidelines has not been studied. This was a retrospective cohort study of individuals 15 to 67 years of age who satisfied a validated case definition of asthma in the administrative health database of British Columbia, Canada between 2002 and 2013. Each patient-year was assessed for inappropriate and excessive prescription of short-acting beta-agonists (SABAs) and the balance between controller and reliever medications. Trends on three time axes were evaluated: calendar time, time course of asthma, and age. Poisson regression was used to test for a linear trend. Three hundred fifty-six thousand, one hundred twelve patients (56.5% female sex; mean age, 30.5 years) contributed 2.6 million patient-years. In 7.3% of the patient-years, SABAs were prescribed inappropriately. This proportion dropped by a relative rate of 5.3% per year (P < .001). In the first year of asthma, 6.3% of patients had indicators of inappropriate SABA use, which dropped within the first 3 years but increased thereafter. Excessive prescription of SABAs increased rapidly during the time course of asthma (change of 23.3% per year; P < .001) and by age (change of 5.1% per year; P < .001). Despite overwhelming evidence regarding the risks, inappropriate prescription for SABAs was prevalent. Excessive SABA use might explain high asthma mortality in older patients. Inappropriate prescriptions declined over the study period but increased over the time course of asthma. These trends might have contributed to the declining asthma hospitalization rates in British Columbia, but there remain gaps in care and potential for improvement in asthma outcomes.

Exercise-induced bronchoconstriction (EIB) can lead to long-term respiratory illness and even death. EIB prevalence rates are both high and variable in college athletes. Also, prevalence rates may be underestimated due to ineffective screening. The purpose of this study is to investigate the prevalence of EIB and the perceived impact of EIB in college athletes via a self-report questionnaire. A self-report EIB questionnaire was administered to college athletes on 8 different sports teams. Information collected was used to identify athletes who self-reported: (1) a history of EIB and/or asthma, (2) respiratory symptoms during exercise, (3) medication use, and (4) concern about EIB. Results showed that 56 of 196 athletes (28.6%) self-reported a history of EIB or asthma. Over half (52%) reported a history of EIB/asthma or current EIB symptoms. Forty-six of the 140 athletes (32.9%) who did not report a history of EIB or asthma indicated symptoms of EIB during sports, training, or exercise. Fourteen of 56 athletes (25%) self-reporting a history of EIB or asthma did not report the use of a respiratory medication. Nineteen of 196 athletes (9.7%) reported being concerned that EIB was adversely affecting their sports performance. College athletes self-report a high prevalence of EIB or asthma. Although college athletes may not report a history of EIB or asthma, they indicate symptoms of EIB. A majority of athletes reported a history or current symptoms related to EIB or asthma. Many athletes with a history of EIB or asthma are not taking any asthma medication. Last, athletes report concern about EIB adversely affecting their sports performance. More work is needed using a combination of a screening questionnaire and standardized EIB testing to develop a validated tool for accurately screening and diagnosing EIB in college athletes.

The first aim of the study (i) assess the current asthma status of general-practitioner-managed patients receiving regular fixed-dose combination inhaled corticosteroid and long-acting beta 2 agonist (FDC ICS/LABA) therapy and (ii) explore patients' perceptions of asthma control and attitudes/behaviors regarding preventer inhaler use. A cross-sectional observational study of Australian adults with a current physician diagnosis of asthma receiving ≥2 prescriptions of FDC ICS/LABA therapy in the previous year, who were recruited through general practice to receive a structured in-depth asthma review between May 2012 and January 2014. Descriptive statistics and Chi-Square tests for independence were used for associations across asthma control levels. Only 11.5% of the patients had controlled asthma based on guideline-defined criteria. Contrarily, 66.5% of the patients considered their asthma to be well controlled. Incidence of acute asthma exacerbations in the previous year was 26.5% and 45.6% of the patients were without a diagnosis of rhinitis. Asthma medication use and inhaler technique were sub-optimal; only 41.0% of the preventer users reported everyday use. The side effects of medication were common and more frequently reported among uncontrolled and partially controlled patients. The study revealed the extent to which asthma management needs to be improved in this patient cohort and the numerous unmet needs regarding the current state of asthma care. Not only there is a need for continuous education of patients, but also education of health care practitioners to better understand the way in which patient's perceptions impact on asthma management practices, incorporating these findings into clinical decision making.

Tobacco Product Use Among Youths With and Without Lifetime Asthma - Florida, 2016.

PubMed

Reid, Keshia M; Forrest, Jamie R; Porter, Lauren

2018-06-01

The increasing availability of diverse tobacco products has led to complex tobacco product use patterns among youths (1). Use by youths of products containing nicotine in any form is unsafe (2); among young persons with asthma, use of combustible tobacco products, particularly cigarettes, is associated with worsening symptoms, poor asthma control, and an increased need for medical management (3,4). Studies suggest that youths with asthma adopt health risk behaviors, including tobacco product use, at rates similar to or higher than those of youths without asthma (3-7); however, these studies are often limited to a partial list of tobacco product types among high school students. To assess current use (≥1 days during the past 30 days) of one or more of five tobacco product types (cigarettes, electronic cigarettes [defined as e-cigarettes, e-cigars, vape pipes, vaping pens, e-hookah, and hookah pens], hookah, smokeless tobacco, or cigars) among Florida middle school (grades 6-8) and high school (grades 9-12) students with or without a previous medical diagnosis of asthma, the Florida Department of Health analyzed data from the 2016 Florida Youth Tobacco Survey (FYTS). In 2016, 11.1% of middle school and 27.9% of high school students with asthma, and 7.9% of middle school and 24.2% of high school students without asthma, reported any current tobacco product use. Current use of each tobacco product type was considerably higher among students with asthma than among those without asthma. E-cigarettes were the most commonly used tobacco product type reported by middle and high school students with asthma (7.9% and 19.6%, respectively) and without asthma (5.8% and 17.2%, respectively). Statewide tobacco prevention strategies could help reduce all forms of tobacco product use among youths, particularly among those with asthma.

The frequency of asthma exacerbations and healthcare utilization in patients with asthma from the UK and USA.

Asthma exacerbations are frequent in patients with severe disease. This report describes results from two retrospective cohort studies describing exacerbation frequency and risk, emergency department (ED)/hospital re-admissions, and asthma-related costs by asthma severity in the US and UK. Patients with asthma in the US-based Clinformatics™ DataMart Multiplan IMPACT (2010-2011; WEUSKOP7048) and the UK-based Clinical Practice Research Datalink (2009-2011; WEUSKOP7092) databases were categorized by disease severity (Global Initiative for Asthma [GINA]; Step and exacerbation history) during the 12 months pre-asthma medical code (index date). Outcomes included: frequency of exacerbations (asthma-related ED visit, hospitalization, or oral corticosteroid use with an asthma medical code recorded within ±2 weeks) 12 months post-index, asthma-related ED visits/hospitalization, and asthma-related costs 30 days post-index. Risk of a subsequent exacerbation was determined by proportional hazard model. Of the 222,817 and 211,807 patients with asthma included from the US and UK databases, respectively, 12.5 and 8.4% experienced ≥1 exacerbation during the follow-up period. Exacerbation frequency increased with disease severity. Among the 5,167 and 2,904 patients with an asthma-related ED visit/hospitalization in the US and UK databases, respectively, 9.2 and 4.7% had asthma-related re-admissions within 30 days. Asthma-related re-admission rates and costs increased with disease severity, approximately doubling between GINA Step 1 and 5 and in patients with ≥2 versus <2 exacerbations in the previous year. Risk of a subsequent exacerbation increased 32-35% for an exacerbation requiring ED visit/hospitalization versus oral corticosteroids. Increased disease severity was associated with higher exacerbation frequency, ED/hospitalization re-admission, costs and risk of subsequent exacerbation, indicating that these patients require high-intensity post-exacerbation management.

2017-05-01

Due to the aging population, there is an increase in the number of elderly patients with asthma. Although signs and symptoms are similar to those in younger patients, diagnosis can be challenging due to presence of coexisting conditions in this population. The purpose of this review was to highlight the challenges with regards to diagnosis, management, the high rates of medical costs and mortality in elderly asthmatics. Scientific literature regarding asthma in the elderly population was reviewed. When compared to younger patients, elderly asthmatics have different drug responses, higher rates of bronchial hyper reactivity, more severe phenotype, and lower prevalence of atopy. In addition, there are issues with the adverse effects of asthma medications, use of proper inhaler technique and compliance. There is an unmet need for research in elderly patients with asthma, specifically to facilitate diagnosis, and to investigate therapeutic strategies to improve quality of life in this population.

2017-08-01

The current study focused on the role of trait mindfulness in asthma-related quality of life (QoL) and asthma control in adolescent asthma patients. Furthermore, potential underlying mechanisms (general and asthma-specific stress) of this relationship were investigated. In this cross-sectional study, questionnaire data of 94 adolescents with asthma that were prescribed daily asthma medication were included. Two Structural Equation Models (SEMs), a direct model and an indirect model, were tested. We found that trait mindfulness was directly related to asthma-related QoL, but not to asthma control. The relationship between trait mindfulness and asthma-related QoL was explained by asthma-specific, but not by general stress. Furthermore, an indirect relation from mindfulness to asthma control via asthma-specific stress was found. Cross-sectional evidence for a relation between mindfulness and asthma-related QoL is found. These findings may point to the possibility that an intervention aimed at increasing mindfulness could be a promising tool to improve asthma-related QoL in adolescents via a decrease in asthma-specific stress.

2016-01-01

Purpose Currently, 7.1 million children in the United States have asthma. Nonadherence to daily controller asthma medication is common, leading to more severe symptoms, overuse of rescue medication, and increased hospitalizations. The purpose of this study was to develop and evaluate the feasibility and acceptability of a novel mHealth management system composed of a sensored device, which is connected to mobile phone app that is designed to monitor and improve asthma medication adherence. Patients and methods The asthma management system was designed using well-established behavioral theory. Seven adolescents aged 11–18 years were enrolled and given an adherence sensor, and four of those also received a mobile phone app with game features and reminders. Five patients completed the study, and one was lost to follow-up in each group. Mobile app users and their parents participated in focus groups to assess patient preferences. Feasibility was assessed by the ability of sensors to capture real-time medication data. Acceptability was assessed by patient questionnaire and focus group analysis. Results Successful upload of real-time data from six of seven inhaler sensors to the HIPAA-compliant server demonstrates the feasibility of at-home patient monitoring using the sensor device. All three mobile app users who completed the study reported interest in continued use of the management system and would recommend the app to friends. Unstructured interviews and focus groups revealed that patients felt that the intervention helped their sense of asthma control. Conclusion This study demonstrates the feasibility of using the sensor device to remotely monitor real-time medication usage, and user feedback demonstrates the acceptability of the intervention for patient use. The findings provide guidance for the improvement of study design and technology development. Further research is needed to assess the efficacy of the intervention. PMID:27853357

To examine the effect of maternal exposure to asthma medications on the risk of congenital anomalies. Meta-analysis of aggregated data from three cohort studies. Linkage between healthcare databases and EUROCAT congenital anomaly registries. 519 242 pregnancies in Norway (2004-2010), Wales (2000-2010) and Funen, Denmark (2000-2010). Exposure defined as having at least one prescription for asthma medications issued (Wales) or dispensed (Norway, Denmark) from 91 days before to 91 days after the pregnancy start date. Odds ratios (ORs) were estimated separately for each register and combined in meta-analyses. ORs for all congenital anomalies and specific congenital anomalies. Overall exposure prevalence was 3.76%. For exposure to asthma medication in general, the adjusted OR (adjOR) for a major congenital anomaly was 1.21 (99% CI 1.09-1.34) after adjustment for maternal age and socioeconomic position. The OR of anal atresia was significantly increased in pregnancies exposed to inhaled corticosteroids (3.40; 99% CI 1.15-10.04). For severe congenital heart defects, an increased OR (1.97; 1.12-3.49) was associated with exposure to combination treatment with inhaled corticosteroids and long-acting beta-2-agonists. Associations with renal dysplasia were driven by exposure to short-acting beta-2-agonists (2.37; 1.20-4.67). The increased risk of congenital anomalies for women taking asthma medication is small with little confounding by maternal age or socioeconomic status. The study confirmed the association of inhaled corticosteroids with anal atresia found in earlier research and found potential new associations with combination treatment. The potential new associations should be interpreted with caution due to the large number of comparisons undertaken. This cohort study found a small increased risk of congenital anomalies for women taking asthma medication. © 2016 The Authors.

The impact of gender on asthma in the daily clinical practice.

PubMed

Ciprandi, Giorgio; Gallo, Fabio

2018-03-01

It is up-to-date to consider the potential gender impact on a disease. There are few data about gender difference in asthma. Therefore, the present cross-sectional study tested this hypothesis in a real-life setting to investigate possible difference between genders. This study was cross-sectional, considering 554 consecutive outpatients suspected of asthma, who were referred for a first specialist visit. Clinical and functional parameters were evaluated. Females with asthma could have a worse perception of asthma control, assessed by asthma control test (ACT), and more anxiety than asthmatic males. However, there was no difference regarding asthma control grading, asthma severity, and asthma medication use between genders; the differences in lung function were without clinical relevance. In the daily clinical practice, it is relevant to consider gender in the management of asthma.

This article reports on the development of a personalized, Web-based asthma-education program for parents whose 4- to 12-year-old children have moderate to severe asthma. Personalization includes computer-based tailored messages and a human coach to build asthma self-management skills. Computerized features include the Asthma Manager, My Calendar/Reminder, My Goals, and a tailored home page. These are integrated with monthly asthma-education phone calls from an asthmanurse case manager. The authors discuss the development process and issues and describe the current randomized evaluation study to test whether the yearlong integrated intervention can improve adherence to a daily asthma controller medication, asthma control, and parent quality of life to reduce asthma-related healthcare utilization. Implications for health education for chronic disease management are raised. PMID:16928987

Influences of health literacy, judgment skills, and empowerment on asthma self-management practices.

Asthma self-management has been recognized as an essential factor for the improvement of asthma outcomes and patients' quality of life (WHO, 2013). Likewise, empowerment and health literacy have been noted as important elements for the management of chronic diseases. To study the influence of health literacy and empowerment on asthma self-management. This cross-sectional study used a self-reported questionnaire assessing health literacy, judgment skills, empowerment, and asthma self-management; 236 patients were recruited from medical offices in Switzerland and Italy. Judgment skills (B=2.28, p<0.001) and empowerment (B=0.19, p<0.05) have a significant and positive influence on several asthma self-management practices such as use of medicines, timely medical consultation, and asthma triggers control whereas health literacy (B=-0.15, p<0.175) appeared to have a negative effect on self-management practices. However, this was not significant. These findings suggest that empowered patients with adequate judgment skills carry out key self-management tasks more appropriately, which in turn will potentially result in better asthma control. This study recommends that both empowerment and judgment skills should be addressed in patient education as they serve as essential motivators to engage patients in these behaviors.

To explore, in depth, the literature for evidence supporting asthma interventions delivered within primary schools and to identify any "gaps" in this research area. A literature search using electronic search engines (i.e. Medline, PubMed, Education Resources Information Center (ERIC), International Pharmaceutical Abstracts (IPA), Cumulative Index to Nursing and Allied Health Literature (CINAHL), Embase and Informit) and the search terms "asthma", "asthma intervention" and "school-based asthma education program" (and derivatives of these keywords) was conducted. Twenty-three articles met the inclusion criteria; of these eight were Randomised Controlled Trials. There was much variety in the type, content, delivery and outcome measures in these 23 studies. The most common intervention type was asthma education delivery. Most studies demonstrated improvement in clinical and humanistic markers, for example, asthma symptoms medication use (decrease in reliever medication use or decrease in the need for rescue oral steroid), inhaler use technique and spacer use competency, lung function and quality of life. Relatively few studies explored the effect of the intervention on academic outcomes. Most studies did not report on the sustainability or cost effectiveness of the intervention tested. Another drawback in the literature was the lack of details about the intervention and inconsistency in instruments selected for measuring outcomes. School-based asthma interventions regardless of their heterogeneity have positive clinical, humanistic, health economical and academic outcomes.

The Tempest: Difficult to Control Asthma in Adolescence.

Burg, Gregory T; Covar, Ronina; Oland, Alyssa A; Guilbert, Theresa W

Severe asthma is associated with significant morbidity and is a highly heterogeneous disorder. Severe asthma in adolescence has some unique elements compared with the features of severe asthma a medical provider would see in younger children or adults. A specific focus on psychological issues and adherence highlights some of the challenges in the management of asthma in adolescents. Treatment of adolescents with severe asthma now includes 3 approved biologic phenotype-directed therapies. Therapies available to adults may be beneficial to adolescents with severe asthma. Research into predictors of specific treatment response by phenotypes is ongoing. Optimal treatment strategies are not yet defined and warrant further investigation.

2016-01-01

Background Inner-city, minority children with asthma have the highest rates of morbidity and death from asthma and the lowest rates of asthma controller medication adherence. Some recent electronic medication monitoring interventions demonstrated dramatic improvements in adherence in lower-risk populations. The feasibility and acceptability of such an intervention in the highest-risk children with asthma has not been studied. Objective Our objective was to assess the feasibility and acceptability of a community health worker-delivered electronic adherence monitoring intervention among the highest utilizers of acute asthma care in an inner-city practice. Methods This was a prospective cohort pilot study targeting children with the highest frequency of asthma-related emergency department and hospital care within a local managed care Medicaid plan. The 3-month intervention included motivational interviewing, electronic monitoring of controller and rescue inhaler use, and outreach by a community health worker for predefined medication alerts. We measured acceptability by using a modified technology acceptability model and changes in asthma control using the Asthma Control Test (ACT). Given prominent feasibility issues, we describe qualitative patterns of medication use at baseline only. Results We enrolled 14 non-Hispanic black children with a median age of 3.5 years. Participants averaged 7.8 emergency or hospital visits in the year preceding enrollment. We observed three distinct patterns of baseline controller use: 4 patients demonstrated sustained use, 5 patients had periodic use, and 5 patients lapsed within 2 weeks. All participants initiated use of the electronic devices; however, no modem signal was transmitted for 5 or the 14 participants after a mean of 45 days. Of the 9 (64% of total) caregivers who completed the final study visit, all viewed the electronic monitoring device favorably and would recommend it to friends, and 5 (56%) believed that the device helped to improve asthma control. ACT scores improved by a mean of 2.7 points (P=.05) over the 3-month intervention. Conclusions High-utilizer, minority families who completed a community health worker-delivered electronic adherence intervention found it generally acceptable. Prominent feasibility concerns, however, such as recruitment, data transmission failure, and lost devices, should be carefully considered when designing interventions in this setting. PMID:27335355

Preventing and lessening exacerbations of asthma in school-age children associated with a new term (PLEASANT): study protocol for a cluster randomised control trial

PubMed Central

2013-01-01

Background Within the UK, during September, there is a pronounced increase in the number of unscheduled medical contacts by school-aged children (4–16 years) with asthma. It is thought that that this might be caused by the return back to school after the summer holidays, suddenly mixing with other children again and picking up viruses which could affect their asthma. There is also a drop in the number of prescriptions administered in August. It is possible therefore that children might not be taking their medication as they should during the summer contributing to them becoming ill when they return to school. It is hoped that a simple intervention from the GP to parents of children with asthma at the start of the summer holiday period, highlighting the importance of maintaining asthma medication can help prevent increased asthma exacerbation, and unscheduled NHS appointments, following return to school in September. Methods/design PLEASANT is a cluster randomised trial. A total of 140 General Practices (GPs) will be recruited into the trial; 70 GPs randomised to the intervention and 70 control practices of “usual care”. An average practice is expected to have approximately 100 children (aged 4–16 with a diagnosis of asthma) hence observational data will be collected on around 14000 children over a 24-month period. The Clinical Practice Research Datalink will collect all data required for the study which includes diagnostic, prescription and referral data. Discussion The trial will assess whether the intervention can reduce exacerbation of asthma and unscheduled medical contacts in school-aged children associated with the return to school after the summer holidays. It has the potential to benefit the health and quality of life of children with asthma while also improving the effectiveness of NHS services by reducing NHS use in one of the busiest months of the year. An exploratory health economic analysis will gauge any cost saving associated with the intervention and subsequent impacts on quality of life. If results for the intervention are positive it is hoped that this could be adopted as part of routine care management of childhood asthma in general practice.

The purpose of this study was to investigate whether uncontrolled asthma was associated with healthcare outcomes among Latin American patients with asthma. We used data from 2168 patients with asthma who participated in the 2011 Latin America Asthma Insights and Management (AIM) survey. Using Global Initiative for Asthma (GINA) guidelines, patients were categorized as having asthma that was well-controlled, partly controlled, or uncontrolled. Overall, 7% of the patients surveyed had asthma that was classified as well-controlled. Patients whose asthma was not well-controlled were significantly more likely to report use of asthma medications (ORs ranging from 1.6-41) and to have had emergency healthcare visits or hospitalizations for their asthma in the previous year (ORs ranging from 2.1 to 5.9). They also reported decreases in their productivity compared to patients with well-controlled asthma. These associations suggest that emphasis on improving asthma control could have substantial effects on patient productivity and utilization of healthcare resources. © 2013 John Wiley & Sons A/S.

Asthma is under-diagnosed in many parts of the world. We aimed to assess the outcome of a capacitating program on asthma for non-specialist physicians and other healthcare professionals working in the public system in Ribeirão Preto, Brazil. A group of 16 asthma specialists developed a one-year capacitating program in 11 healthcare clinics in the Northern District of the city, which included lectures on asthma, training on inhalation device use and spirometry, and development of an asthma management protocol. Researchers visited one health unit 2-4 times monthly, working with doctors on patients' care, discussing cases, and delivering lectures. Asthma education was also directed to the general population, focusing on recognition of signs and symptoms and long-term treatment, including production of educational videos available on YouTube. Outcome measures were the records of doctors' prescriptions of individual asthma medications pre- and post-intervention. Prior to the program, 3205 units of inhaled albuterol and 2876 units of inhaled beclomethasone were delivered by the Northern District pharmacy. After the one-year program, there was increase to 4850 units (51.3%) for inhaled albuterol and 3526 units (22.6%) for inhaled beclomethasone. The albuterol increase followed the recommendation given to the non-specialist doctors by the asthma experts, that every patient with asthma should have inhaled albuterol as a rescue medication, by protocol. No increase was observed in other districts where no capacitating program was conducted. A systematic capacitating program was successful in changing asthma prescription profiles among non-specialist doctors, with increased delivery of inhaled albuterol and beclomethasone.

Background A trans-generational influence of prenatal tobacco smoke exposure on asthma development has been proposed but the evidence remains sparse. Methods We examined the grandmother’s smoking when pregnant with the mother in relation to asthma outcomes in the grandchild [current asthma at 36 months (N=53,169,cases=3,013), current asthma at 7 years (N=25,394,cases=1,265) and dispensed asthma medications at 7 years in the Norwegian Prescription Database (N=45,607,cases=1,787)] within the Norwegian Mother and Child Cohort Study(MoBa). We calculated adjusted relative risks (adj. RR) and 95% confidence intervals (CI) using log binomial regression. Results A total of 23.5% of mothers reported that their mother smoked when pregnant with them. The grandmother’s smoking when pregnant with the mother was positively associated with asthma at 36 months [adj.RR 1.15 (95% CI: 1.06, 1.24)], asthma at 7 years [adj.RR 1.21 (95% CI: 1.07, 1.37)] and dispensed asthma medications at 7 years [adj.RR 1.15 (95% CI: 1.04, 1.26)]. This positive association did not differ significantly by the mother’s smoking status when pregnant with the child (P-values for multiplicative interaction >0.1). Conclusion The grandmother’s smoking when pregnant with the mother increased the risk of asthma in the grandchild independent of the mother’s smoking status. However, given limited information on the grandmother’s socio-economic status, asthma status and other factors, unmeasured confounding may be present. PMID:25572596

Opportunities to develop the professional role of community pharmacists in the care of patients with asthma: a cross-sectional study

There are many indications in Australia and globally that asthma management is suboptimal. Ideally, patients need to proactively self-manage the condition with the support of health professionals. Community pharmacists are a highly accessible resource for patients but currently provide inconsistent services. General practitioners also face many barriers to the provision of chronic disease management for asthma patients. The aim of this research was to characterise patients with asthma who present to community pharmacy. The objective was to identify opportunities to develop the role of pharmacists in the context of the primary healthcare setting and in view of the needs of the patients they routinely encounter. The results of a comprehensive survey of 248 patients recruited from community pharmacies indicated there was discordance between patient perceptions of asthma control and actual asthma control. Almost half the patients surveyed had poorly controlled asthma, whereas almost three quarters perceived their asthma to be well or completely controlled. Fewer than 20% of patients were utilising written asthma action plans, and issues around quality use of medicines were identified. The significance of the incongruent perceptions regarding asthma control is that patients are unlikely to proactively seek intervention and support from healthcare professionals. Community pharmacists provide a significant opportunity to address these issues by direct intervention. There is scope to investigate pharmacists preparing written asthma action plans for patients, using software to monitor medication adherence and prescribe on-going medication. To maximise the potential of pharmacists, barriers to practice need to be identified and addressed. PMID:27883003

Cannabis-Associated Asthma and Allergies.

Inhalation of cannabis smoke is its most common use and the pulmonary complications of its use may be the single most common form of drug-induced pulmonary disease worldwide. However, the role of cannabis consumption in asthma patients and allergic clinical situations still remains controversial. To review the evidence of asthma and allergic diseases associated with the use of marijuana, we conducted a search of English, Spanish, and Portuguese medical using the search terms asthma, allergy, marijuana, marihuana, and cannabis. Entries made between January 1970 and March 2017 were retrieved. Several papers have shown the relationship between marijuana use and increase in asthma and other allergic diseases symptoms, as well as the increased frequency of medical visits. This narrative review emphasizes the importance to consider cannabis as a precipitating factor for acute asthma and allergic attacks in clinical practice. Although smoking of marijuana may cause respiratory symptoms, there is a need for more studies to elucidate many aspects in allergic asthma patients, especially considering the long-term use of the drug. These patients should avoid using marijuana and be oriented about individual health risks, possible dangers of second-hand smoke exposure, underage use, safe storage, and the over smoking of marijuana.

Objectives The optimal method of identifying people with asthma from electronic health records in primary care is not known. The aim of this study is to determine the positive predictive value (PPV) of different algorithms using clinical codes and prescription data to identify people with asthma in the United Kingdom Clinical Practice Research Datalink (CPRD). Methods 684 participants registered with a general practitioner (GP) practice contributing to CPRD between 1 December 2013 and 30 November 2015 were selected according to one of eight predefined potential asthma identification algorithms. A questionnaire was sent to the GPs to confirm asthma status and provide additional information to support an asthma diagnosis. Two study physicians independently reviewed and adjudicated the questionnaires and additional information to form a gold standard for asthma diagnosis. The PPV was calculated for each algorithm. Results 684 questionnaires were sent, of which 494 (72%) were returned and 475 (69%) were complete and analysed. All five algorithms including a specific Read code indicating asthma or non-specific Read code accompanied by additional conditions performed well. The PPV for asthma diagnosis using only a specific asthma code was 86.4% (95% CI 77.4% to 95.4%). Extra information on asthma medication prescription (PPV 83.3%), evidence of reversibility testing (PPV 86.0%) or a combination of all three selection criteria (PPV 86.4%) did not result in a higher PPV. The algorithm using non-specific asthma codes, information on reversibility testing and respiratory medication use scored highest (PPV 90.7%, 95% CI (82.8% to 98.7%), but had a much lower identifiable population. Algorithms based on asthma symptom codes had low PPVs (43.1% to 57.8%)%). Conclusions People with asthma can be accurately identified from UK primary care records using specific Read codes. The inclusion of spirometry or asthma medications in the algorithm did not clearly improve accuracy. Ethics and dissemination The protocol for this research was approved by the Independent Scientific Advisory Committee (ISAC) for MHRA Database Research (protocol number15_257) and the approved protocol was made available to the journal and reviewers during peer review. Generic ethical approval for observational research using the CPRD with approval from ISAC has been granted by a Health Research Authority Research Ethics Committee (East Midlands—Derby, REC reference number 05/MRE04/87). The results will be submitted for publication and will be disseminated through research conferences and peer-reviewed journals. PMID:28801439

Prevalence of asthma in elite athletes shows very wide ranges. It remains unclear to what extent this is influenced by the competition season (winter vs. summer) or the ventilation rate achieved during competition. The aim of this study was to evaluate prevalence of asthma in German elite winter and summer athletes from a wide range of sport disciplines and to identify high risk groups. In total, 265 German elite winter athletes (response 77%) and 283 German elite summer athletes (response 64%) answered validated respiratory questionnaires. Using logistic regression, the asthma risks associated with competition season and ventilation rate during competition, respectively, were investigated. A subset of winter athletes was also examined for their FENO-levels and lung function. With respect to all asthma outcomes, no association was found with the competition season. Regarding the ventilation rate, athletes in high ventilation sports were at increased risk of asthma, as compared to athletes in low ventilation sports (doctors' diagnosed asthma: OR 2.32, 95% CI 1.19-4.53; use of asthma medication: OR 4.46, 95% CI 1.52-13.10; current wheeze or use of asthma medication: OR 2.78, 95% CI 1.34-5.76). Athletes with doctors' diagnosed asthma were at an approximate four-fold risk of elevated FENO-values. The clinically relevant finding of this study is that athletes' asthma seems to be more common in sports with high ventilation during competition, whereas the summer or winter season had no impact on the frequency of the disease. Among winter athletes, elevated FENO suggested suboptimal control of asthma. Copyright © 2016 Elsevier Ltd. All rights reserved.

Background US national guidelines recommend assessing short-acting β-agonist (SABA) medication use as a marker of asthma severity and control. However, the relationship between recent SABA use and asthma exacerbations is not currently known. Objective To evaluate the proximal relationship between the type and frequency of SABA use and asthma-related outcomes. Methods We evaluated SABA use among patients with asthma ages 5 to 56 years who were members of a large health maintenance organization in southeast Michigan. Frequency of use was estimated from pharmacy data assessing the timing and amount of SABA fills. Cox proportional hazards models were used to examine the prospective relationship between average daily SABA use for 3 months and outcomes associated with poor asthma control (ie, oral corticosteroids use, asthma-related emergency department visits, and asthma-related hospitalizations). We separately accounted for SABA metered-dose inhaler (MDI) and SABA nebulizer use. Results Of the 2,056 patients who met study criteria, 1,569 (76.3%) had used a SABA medication in their baseline year. After adjusting for potential confounders, SABA nebulizer use was associated with asthma-related emergency department visits (adjusted hazard ratio [aHR], 6.32; 95% confidence interval [CI], 2.38 to 16.80) and asthma-related hospitalizations (aHR, 21.62; 95% CI, 3.17 to 147.57). In contrast, frequency of SABA MDI use was not associated with these outcomes. Conclusions Frequency of SABA use during a 3-month period was associated with poor asthma outcomes. The relationship with poor asthma outcomes was strongest for SABA nebulizer use, suggesting that the type of SABA used is also of prognostic importance. PMID:19055201

Although asthma self-management plans are widely recommended as essential in the long-term treatment of adult asthma, there have been few studies examining their use. Our objective was to assess the effect of a "credit card" adult asthma self-management plan in a community experiencing major health problems from asthma, by means of a before and after intervention trial of the efficacy of the "credit card" plan, when introduced through community-based asthma clinics. The participants were 69 Maori people with asthma. The "credit card" plan consisted of written guidelines for the self-management of asthma, based on self-assessment of asthma severity, printed on a plastic card. On one side, management guidelines were based on the interpretation of peak expiratory flow rate (PEFR) recordings, whilst the reverse side was based on symptoms. The outcome measures used were before and after comparison of markers of asthma morbidity and requirement for acute medical treatment; and a structured questionnaire assessing the acceptability and use of the credit card plan. Following the introduction of the plan, the mean PEFR increased from 347 to 389 l.min-1, the percentage of nights woken fell from 30.4 to 16.9%, and the number of days "out of action" fell from 3.8 to 1.7%. The requirements for acute medical treatment also fell during the intervention period. Most participants commented favourably on the content and usefulness of the plan. In the situation of worsening asthma, 28% of subjects found the peak flow side of the card most helpful, 7% the symptoms side, and 48% found both sides equally helpful.(ABSTRACT TRUNCATED AT 250 WORDS)

Gastroesophageal reflux disease is one of the most common comorbidities in patients with asthma. Gastroesophageal reflux disease can be linked to difficult-to-control asthma. Current management includes gastric acid suppression therapy and surgical antireflux procedures. The LINX® procedure is a novel surgical treatment for patients with gastroesophageal reflux disease refractory to medical therapy. To the best of our knowledge, we report the first case of successful treatment of refractory asthma secondary to gastroesophageal reflux disease using the LINX® procedure. Our patient was a 22-year-old white woman who met the American Thoracic Society criteria for refractory asthma that had remained poorly controlled for 5 years despite progressive escalation to step 6 treatment as recommended by National Institutes of Health-National Asthma Education and Prevention Program guidelines, including high-dose oral corticosteroids, high-dose inhaled corticosteroid plus long-acting β2-agonist, leukotriene receptor antagonist, and monthly omalizumab. Separate trials with azithromycin therapy and roflumilast did not improve her asthma control, nor did bronchial thermoplasty help. Additional consultations with two other university health systems left the patient with few treatment options for asthma, which included cyclophosphamide. Instead, the patient underwent a LINX® procedure after failure of maximal medical therapy for gastroesophageal reflux disease with the additional aim of improving asthma control. After she underwent LINX® treatment, her asthma improved dramatically and was no longer refractory. She had normal exhaled nitric oxide levels and loss of peripheral eosinophilia after LINX® treatment. Prednisone was discontinued without loss of asthma control. The only immediate adverse effects due to the LINX® procedure were bloating, nausea, and vomiting. LINX® is a viable alternative to the Nissen fundoplication procedure for the treatment of patients with gastroesophageal reflux disease and poorly controlled concomitant refractory asthma.

To use community pharmacy medication records to identify patients whose asthma may not be well managed and then implement and evaluate a multidisciplinary educational intervention to improve asthma management. We used a multisite controlled study design. Forty-two pharmacies throughout Tasmania ran a software application that "data-mined" medication records, generating a list of patients who had received three or more canisters of inhaled short-acting beta(2)-agonists in the preceding 6 months. The patients identified were allocated to an intervention or control group. Pre-intervention data were collected for the period May to November 2006 and post-intervention data for the period December 2006 to May 2007. Intervention patients were contacted by the community pharmacist via mail, and were sent educational material and a letter encouraging them to see their general practitioner for an asthma management review. Pharmacists were blinded to the control patients' identities until the end of the post-intervention period. Dispensing ratio of preventer medication (inhaled corticosteroids [ICSs]) to reliever medication (inhaled short-acting beta(2)-agonists). Thirty-five pharmacies completed the study, providing 702 intervention and 849 control patients. The intervention resulted in a threefold increase in the preventer-to-reliever ratio in the intervention group compared with the control group (P < 0.01) and a higher proportion of patients in the intervention group using ICS therapy than in the control group (P < 0.01). Community pharmacy medication records can be effectively used to identify patients with suboptimal asthma management, who can then be referred to their GP for review. The intervention should be trialled on a national scale to determine the effects on clinical, social, emotional and economic outcomes for people in the Australian community, with a longer follow-up to determine sustainability of the improvements noted.

Asthma and the employment experience.

Previous asthma research has had a medical focus, and only one study has investigated the relationship between asthma and employment. This study describes the employment experience in relation to occupational choice and career advancement in 93 sequentially selected adult asthmatics attending a hospital based asthma clinic serving a socially disadvantaged urban population. Repeated hospital admissions and frequent asthma related sick leave from work were identified as contributing factors to employer discrimination, job dismissal, and lack of career advancement. Seventy-seven percent had not informed their employers of their asthma and 32% of those currently employed stated that getting time off work was a problem in relation to Asthma Clinic attendance. Of those not employed, 22.9% were receiving sickness or invalid benefits and 8.3% had lost their jobs because of asthma. This study illustrates how the stigma attached to the diagnosis of asthma in this community may not only impact negatively on employment opportunity, but also on asthma care.

The objective of this cross-sectional, retrospective study was to utilize claims data to establish a quality-of-care benchmark in a large multistate Medicaid population overall and by race. Quality of care and medication adherence (persistence and compliance) per national treatment guidelines, and health care costs/utilization were assessed across common chronic conditions in a large, 9-state Medicaid population. Overall, quality of care was suboptimal across conditions. Over 15% of asthma patients had ≥ 1 asthma-related emergency room/hospital event and 12% of chronic obstructive pulmonary disease patients had a Level II or III exacerbation. Only 36% of depression patients filled any antidepressant medication within 90 days of new episode. Only 45% of diabetes patients received ≥ 2 A1c tests. Patients who filled a prescription for any acceptable pharmacotherapy ranged from 35% (depression) to 83% (heart failure [HF]). Persistence for those filling any acceptable medication ranged from 16% (asthma) to 68% (HF). Compliance for patients filling ≥ 2 prescriptions ranged from 27% (asthma) to 75% (HF). Blacks had the lowest medication compliance and persistence for all conditions except hyperlipidemia. The results highlight the need to assess and improve quality across the spectrum of care, both overall and by race.

The circumstances and drivers of the decision to initiate, implement, or persist with a medication differ for individuals at each developmental stage. For school-age children with asthma, the social environment of their family's cultural beliefs and the influence of peer networks and school policies are strong determinants of medication adherence. The stage of adolescence can be a particularly challenging time because there is a reduction in parental supervision of asthma management as the young person strives to become more autonomous. To illustrate the importance of such factors, adherence interventions in children and young adults with asthma have used peer-based supports and social supports, particularly social media platforms. In older patients, it is internal rather than external factors and age-related decline that pose challenges to medication adherence. Seniors face the challenges of polypharmacy, reduced social support, increased isolation, and loss of cognitive function. Strategies to promote adherence must be tailored to the developmental stage and respective behavioral determinants of the target group. This review considers the different attitudes toward medication and the different adherence behaviors in young and elderly patients with chronic respiratory conditions, specifically asthma and chronic obstructive pulmonary disease. Opportunities to intervene to optimize adherence are suggested. Copyright © 2016 The Authors. Published by Elsevier Inc. All rights reserved.

DPP-4 may regulate immunological pathways implicated in asthma. Assessing whether DPP-4 inhibitor (DPP-4i) use might affect asthma control is clinically important because DPP-4i use in type 2 diabetes mellitus management (T2DM) is increasing. This study evaluated associations between DPP-4i use and asthma control. This was a retrospective, observational, matched cohort study using administrative claims in the MarketScan ® Commercial Claims and Encounters (Commercial) and Medicare Supplemental and Coordination of Benefits (Medicare Supplemental) databases. Adult asthma patients initiating an oral DPP-4i or a non-DPP-4i between November 1, 2006 and March 31, 2014 were included. Patients were followed for asthma-related outcomes for 12 months after initiation of the antidiabetes medication. Outcomes included risk-domain asthma control (RDAC), defined as no asthma hospitalizations, no lower respiratory tract infections, and no oral corticosteroid (OCS) prescriptions; overall asthma control (RDAC criteria plus limited short-acting beta agonist use); treatment stability (RDAC criteria plus no increase of ≥50% in inhaled corticosteroid dose or addition of other asthma therapy); and severe asthma exacerbation rates (asthma-related hospitalizations, emergency room visits, or acute treatments with OCS). Comparisons were made between two matched cohorts (DPP-4i vs. non-DPP-4i initiators) using multivariable logistic regression and generalized linear modeling. Covariates included baseline demographic and clinical characteristics related to asthma and T2DM. The adjusted odds of achieving RDAC (odds ratio [OR]: 1.05; 95% CI: 0.964 to 1.147), overall asthma control (OR: 1.04; 95% CI: 0.956 to 1.135), and treatment stability (OR: 1.04; 95% CI: 0.949 to 1.115) did not differ between the DPP-4i and non-DPP-4i cohorts. A difference was not found between cohorts in severe asthma exacerbation rates during the 12 months following initiation of antidiabetes treatment (mean = 0.32 vs. 0.34 exacerbations per subject-year, respectively; p =0.064). Asthma control was similar between patients initiating DPP-4i and non-DPP-4i antidiabetes medications, suggesting no association between DPP-4i use and asthma control.

Asthma is a common childhood chronic lung disease affecting greater than 10% of children in the United States. School nurses are in a unique position to close gaps in care. Indeed, effective asthma management is more likely to result when providers, family, and schools work together to optimize the patient's treatment plan. Currently, effective communication between schools and healthcare systems through electronic medical record (EMR) systems remains a challenge. The goal of this feasibility pilot was to link the school-based care team with primary care providers in the healthcare system network via electronic communication through the EMR, on behalf of pediatric asthma patients who had been hospitalized for an asthma exacerbation. The implementation process and the potential impact of the communication with providers on the reoccurrence of asthma exacerbations with the linked patients were evaluated. By engaging stakeholders from the school system and the healthcare system, we were able to collaboratively design a communication process and implement a pilot which demonstrated the feasibility of electronic communication between school nurses and primary care providers. Outcomes data was collected from the electronic medical record to examine the frequency of asthma exacerbations among patients with a message from their school nurse. The percent of exacerbations in the 12 months before and after electronic communication was compared using McNemar's test. The pilot system successfully established communication between the school nurse and primary care provider for 33 students who had been hospitalized for asthma and a decrease in hospital admissions was observed with students whose school nurse communicated through the EMR with the primary care provider. Findings suggest a collaborative model of care that is enhanced through electronic communication via the EMR could positively impact the health of children with asthma or other chronic illnesses.

Our objective was to develop a series of short educational videos for teens and parents to watch before pediatric visits to motivate teens to be more actively involved during their visits. The development of the short educational videos was theoretically guided by Social Cognitive Theory. First we conducted four focus groups with teens (ages 11 to 17) with asthma, four focus groups with the teens' parents, and seven focus groups with pediatric providers from four clinics. The research team, which included two teens with asthma and their parents, analyzed the focus group transcripts for themes and then developed the initial video script. Next, a visual storyboard was reviewed by focus groups with parents and four with teens to identify areas of the script for improvement. The English videos were then produced. Focus groups with Hispanic parents and teens were then conducted for advice on how to modify the videos to make a more culturally appropriate Spanish version. Based on focus group results, teen newscasters narrate six one- to two-minute videos with different themes: (a) how to get mom off your back, (b) asthma triggers, (c) staying active with asthma, (d) tracking asthma symptoms, (e) how to talk to your doctor and (f) having confidence with asthma. Each video clip has three key messages and emphasizes how teens should discuss these messages with their providers. Teens, parents, and providers gave us excellent insight into developing videos to increase teen involvement during medical visits.

We aimed to ascertain the prevalence of asthma amongst Galway schoolchildren aged 9-10, and to compare the results to a similar study carried out in 1992. A questionnaire was distributed to parents of all children attending 4th class in Galway city schools. 652 of 750(87%) questionnaires were returned. Prevalence of "wheeze ever" was 27.6%, and "current wheeze" 16.3%. The prevalence of asthma was 18.5%. Of those with asthma there was a 2 to 1 male preponderance, 80% had mild asthma, 14% moderate, and 6% severe asthma. 80% were taking anti-asthma therapy, with 48% taking regular inhaled steroids. 84% had a diagnosis of asthma made by a doctor. Comparison with the study of 1992 shows little change in the prevalence of current wheeze, or asthma. There has however been a significant decline in the severity of asthma, and an increase in the use of prophylactic anti-asthma medication. Asthma prevalence appears to be stable in the age group studied. There is a much greater willingness to diagnose, and treat asthma in the community. The severity of asthma, as measured by attack frequency, has declined.

Overuse of asthma relievers, particularly without anti-inflammatory preventers, increases asthma risks. This study aimed to identify how many reliever-only users have urgent healthcare, explore their attitudes and beliefs about asthma and its treatment, and investigate whether purchasing over-the-counter relievers was associated with worse asthma outcomes than by prescription. Cross-sectional population-based Internet survey in Australia. Of 2686 participants ≥16 years with current asthma randomly drawn from a web-based panel, 1038 (50.7% male) used only reliever medication. Urgent asthma-related healthcare; Asthma Control Test (ACT); patient attitudes about asthma and medications; reliever purchase (with/without prescription). Of 1038 reliever-only participants, 23.3% had required urgent healthcare for asthma in the previous year, and only 36.0% had a non-urgent asthma review. Those needing urgent healthcare were more likely than those without such events to be male (56.5% vs 49.0%, p=0.003) and current smokers (29.4% vs 23.3%, p=0.009). Only 30.6% had well-controlled asthma (ACT ≥20) compared with 71.0% of those with no urgent healthcare (p<0.0001), and 20.8% used relievers regularly to prevent asthma symptoms (vs 5.5% of those without urgent healthcare). Those with urgent healthcare were more frustrated by their asthma and less happy with how they managed it, and they were less confident about their ability to manage worsening asthma, but just as likely as those without urgent healthcare to manage worsening asthma themselves rather than visit a doctor. Reliever-only users purchasing over-the-counter relievers were no more likely than those purchasing relievers by prescription to have uncontrolled asthma (35.9% vs 40.6%, p=0.23) but were less likely to have had a non-urgent asthma review. One-quarter of the reliever-only population had needed urgent asthma healthcare in the previous year, demonstrating the importance of identifying such patients. Their attitudes and beliefs suggest opportunities for targeting this population in the community. © Article author(s) (or their employer(s) unless otherwise stated in the text of the article) 2017.

Objective To explore reasons for increased risk of hospital admission among south Asian patients with asthma. Design Qualitative interview study using modified critical incident technique and framework analysis. Setting Newham, east London, a deprived area with a large mixed south Asian population. Participants 58 south Asian and white adults with asthma (49 admitted to hospital with asthma, 9 not admitted); 17 general practitioners; 5 accident and emergency doctors; 2 out of hours general practitioners; 1 asthma specialist nurse. Main outcome measures Patients' and health professionals' views on influences on admission, events leading to admission, general practices' organisation and asthma strategies, doctor-patient relationship, and cultural attitudes to asthma. Results South Asian and white patients admitted to hospital coped differently with asthma. South Asians described less confidence in controlling their asthma, were unfamiliar with the concept of preventive medication, and often expressed less confidence in their general practitioner. South Asians managed asthma exacerbations with family advocacy, without systematic changes in prophylaxis, and without systemic corticosteroids. Patients describing difficulty accessing primary care during asthma exacerbations were registered with practices with weak strategies for asthma care and were often south Asian. Patients with easy access described care suggesting partnerships with their general practitioner, had better confidence to control asthma, and were registered with practices with well developed asthma strategies that included policies for avoiding hospital admission. Conclusions The different ways of coping with asthma exacerbations and accessing care may partly explain the increased risk of hospital admission in south Asian patients. Interventions that increase confidence to control asthma, confidence in the general practitioner, understanding of preventive treatment, and use of systemic corticosteroids in exacerbations may reduce hospital admissions. Development of more sophisticated asthma strategies by practices with better access and partnerships with patients may also achieve this. What is already known on this topicSouth Asian patients with asthma are at increased risk of hospital admission with asthma compared with white patientsNo consistent differences in severity or prevalence of asthma, prescribed drugs, or asthma education have been described, and interventions to reduce admission rates in Asian patients have met with variable successWhat this study addsCompared with white patients, south Asian patients admitted to hospital with asthma had less confidence to control asthma, were unfamiliar with the concept of preventive medication, and had less confidence in their general practitionersSouth Asian patients managed asthma attacks through family advocacy and without systematic changes in prophylaxis and without systemic corticosteroidsPatients reporting difficulty in accessing primary care during attacks were often south Asian PMID:11679384

Conducting retrospective impact analysis to inform a medical research charity’s funding strategies: the case of Asthma UK

PubMed Central

2013-01-01

Background Debate is intensifying about how to assess the full range of impacts from medical research. Complexity increases when assessing the diverse funding streams of funders such as Asthma UK, a charitable patient organisation supporting medical research to benefit people with asthma. This paper aims to describe the various impacts identified from a range of Asthma UK research, and explore how Asthma UK utilised the characteristics of successful funding approaches to inform future research strategies. Methods We adapted the Payback Framework, using it both in a survey and to help structure interviews, documentary analysis, and case studies. We sent surveys to 153 lead researchers of projects, plus 10 past research fellows, and also conducted 14 detailed case studies. These covered nine projects and two fellowships, in addition to the innovative case studies on the professorial chairs (funded since 1988) and the MRC-Asthma UK Centre in Allergic Mechanisms of Asthma (the ‘Centre’) which together facilitated a comprehensive analysis of the whole funding portfolio. We organised each case study to capture whatever academic and wider societal impacts (or payback) might have arisen given the diverse timescales, size of funding involved, and extent to which Asthma UK funding contributed to the impacts. Results Projects recorded an average of four peer-reviewed journal articles. Together the chairs reported over 500 papers. All streams of funding attracted follow-on funding. Each of the various categories of societal impacts arose from only a minority of individual projects and fellowships. Some of the research portfolio is influencing asthma-related clinical guidelines, and some contributing to product development. The latter includes potentially major breakthroughs in asthma therapies (in immunotherapy, and new inhaled drugs) trialled by university spin-out companies. Such research-informed guidelines and medicines can, in turn, contribute to health improvements. The role of the chairs and the pioneering collaborative Centre is shown as being particularly important. Conclusions We systematically demonstrate that all types of Asthma UK’s research funding assessed are making impacts at different levels, but the main societal impacts from projects and fellowships come from a minority of those funded. Asthma UK used the study’s findings, especially in relation to the Centre, to inform research funding strategies to promote the achievement of impact. PMID:23651523

Despite significant advances in knowledge of the genetic architecture of asthma, specific contributors to the variability in the burden between populations remain uncovered. To identify additional genetic susceptibility factors of asthma in European American and African American populations. A phenotyping algorithm mining electronic medical records was developed and validated to recruit cases with asthma and control subjects from the Electronic Medical Records and Genomics network. Genome-wide association analyses were performed in pediatric and adult asthma cases and control subjects with European American and African American ancestry followed by metaanalysis. Nominally significant results were reanalyzed conditioning on allergy status. The validation of the algorithm yielded an average of 95.8% positive predictive values for both cases and control subjects. The algorithm accrued 21,644 subjects (65.83% European American and 34.17% African American). We identified four novel population-specific associations with asthma after metaanalyses: loci 6p21.31, 9p21.2, and 10q21.3 in the European American population, and the PTGES gene in African Americans. TEK at 9p21.2, which encodes TIE2, has been shown to be involved in remodeling the airway wall in asthma, and the association remained significant after conditioning by allergy. PTGES, which encodes the prostaglandin E synthase, has also been linked to asthma, where deficient prostaglandin E 2 synthesis has been associated with airway remodeling. This study adds to understanding of the genetic architecture of asthma in European Americans and African Americans and reinforces the need to study populations of diverse ethnic backgrounds to identify shared and unique genetic predictors of asthma.

Studies have shown that reducing exposure to triggers such as air pollutants can reduce symptoms and the need for medication in asthma patients. However, systems that track asthma are generally not integrated with those that track environmental hazards related to asthma. Tlvs lack of integration hinders public health awareness and responsiveness to these environmental triggers. The current study is a collaboration between health and environmental professionals to utilize NASA-derived environmental data to develop a decision support system (DSS) for asthma prediction, surveillance, and intervention. The investigators link asthma morbidity data from the University of Mississippi Medical Center (UMMC) and Mississippi Department of Health (MDH) with air quality data from the Mississippi Department of Environmental Quality (MDEQ) and remote sensing data from NASA. Daily ambient environmental hazard data for PM2.5 and ozone are obtained from the MDEQ air quality monitoring locations and are combined with remotely sensed data from NASA to develop a state-wide spatial and time series profile of environmental air quality. These data are then used to study the correlation of these measures of air quality variation with the asthma exacerbation incidence throughout the state over time. The goal is to utilize these readily available measures to allow real-time risk assessment for asthma exacerbations. GeoMedStat, a DSS previously developed for biosurveillance, will integrate these measures to monitor, analyze and report the real-time risk assessment for asthma exacerbation throughout the state.

The purpose of this study was to investigate whether the presence of substance-related disorders or mental illness may affect the quality of medication management in asthma care. Claims from 1999 for adult Medicaid patients with persistent asthma from five states were analyzed. Sample sizes ranged from 1,207 to 5,815. The adjusted odds of meeting two quality-of-care measures for asthma were calculated: the Health Effectiveness Data and Information Set (HEDIS) measure of filling a single prescription for a controller medication and a non-HEDIS measure of achieving a ratio of long-term controller medications to total asthma medications of > or = .5. Odds of achieving the HEDIS measure were lower for patients with substance-related or schizophrenia disorders in two states (range of odds ratio [OR]=.69, 95% confidence interval [CI]=.53-.90, to OR=.81, 95% CI=.69-.96), but the odds increased for patients with depressive disorders in two states (OR=1.34, CI= 1.12-1.61; OR=1.37, CI=1.05-1.77) and for patients with bipolar disorder in one state (OR=1.69, CI=1.13-2.55). Odds of achieving the ratio measure were lower for patients with substance-related disorders in four states (range of OR=.63, CI=.47-.88, to OR=.75, CI=.62-.92) and higher for patients with depressive disorders, although only in one state (OR=1.25, CI=1.03-1.53). Patients with substance-related disorders and those with schizophrenia disorders may be receiving lower-quality asthma care, whereas patients with some other forms of mental illness may be receiving higher-quality care. Further studies are needed to identify the determinants of high-quality asthma care and the validity of quality measures based on administrative data in these populations.

To determine whether significant numbers of asthmatic children with initially rated intermittent asthma later suffer poor asthma control and require the addition of controller medications. Inner-city Hispanic children were followed prospectively in an asthma-specific disease management system (Breathmobile) for a period of 2 years. Clinical asthma symptoms, morbidity treatment, and demographic data were collected at each visit. Treatment was based upon National Heart, Lung, and Blood Institute (NHLBI) Expert Panel Report 3 asthma guidelines. Primary outcome was percentage of patients with intermittent asthma who had not well or poorly controlled asthma during subsequent visits and required controller agents. Secondary outcomes were factors associated with the maintenance of asthma control. About 30.9% of the patients with initial rating of intermittent asthma had not well controlled and poorly controlled asthma during subsequent visits and required the addition of controller agents. Factors associated with good asthma control were compliance, no previous emergency room visits and previous visit during spring season. Asthmatic children with intermittent asthma often lose asthma control and require controller therapy. This justifies asthma guideline recommendations to assess asthma control at follow-up visits and adjust therapy accordingly.

Previous studies suggested an association between atopic conditions and specific cancers. The results on the association with urothelial bladder cancer (UBC) are scarce and inconsistent. To evaluate the association between asthma and risk of UBC, we considered 936 cases and 1,022 controls from the Spanish Bladder Cancer/EPICURO Study (86% males, mean age 65.4 years), a multicenter and hospital-based case-control study conducted during 1998-2001. Participants were asked whether they had asthma and detailed information about occupational exposures, smoking habits, dietary factors, medical conditions and history of medication was collected through face-to-face questionnaires performed by trained interviewers. Since asthma and UBC might share risk factors, association between patients' characteristics and asthma was studied in UBC controls. Association between UBC and asthma was assessed using logistic regression unadjusted and adjusted for potential confounders. The complex interrelationships, direct and mediating effect of asthma on UBC, were appraised using counterfactual mediation models. Asthma was associated with a reduced risk of UBC (odds ratio (OR) = 0.54, 95% confidence interval (CI) 0.37, 0.79) after adjusting for a wide range of confounders. No mediating effect was identified. The reduced risk associated with asthma was restricted to patients with high-risk non-muscle invasive (OR = 0.25, 95%CI 0.10, 0.62) and muscle invasive UBC (OR = 0.32, 95%CI 0.15, 0.69). Our results support that asthma is associated with a decreased risk of UBC, especially among aggressive tumors. Further work on the relationship between asthma and other atopic conditions and cancer risk should shed light on the relationship between immune response mechanisms and bladder carcinogenesis. © 2017 UICC.

A trans-generational influence of prenatal tobacco smoke exposure on asthma development has been proposed but the evidence remains sparse. We examined the grandmother's smoking when pregnant with the mother in relation to asthma outcomes in the grandchild (current asthma at 36 months (N=53 169, cases=3013), current asthma at 7 years (N=25 394, cases=1265) and dispensed asthma medications at 7 years in the Norwegian Prescription Database (N=45 607, cases=1787)) within the Norwegian Mother and Child Cohort Study (MoBa). We calculated adjusted RR (adj. RR) and 95% CIs using log binomial regression. A total of 23.5% of mothers reported that their mother smoked when pregnant with them. The grandmother's smoking when pregnant with the mother was positively associated with asthma at 36 months (adj. RR 1.15 (95% CI 1.06 to 1.24)), asthma at 7 years (adj. RR 1.21 (95% CI 1.07 to 1.37)) and dispensed asthma medications at 7 years (adj. RR 1.15 (95% CI 1.04 to 1.26)). This positive association did not differ significantly by the mother's smoking status when pregnant with the child (p values for multiplicative interaction >0.1). The grandmother's smoking when pregnant with the mother increased the risk of asthma in the grandchild independent of the mother's smoking status. However, given limited information on the grandmother's socioeconomic status, asthma status and other factors, unmeasured confounding may be present. Published by the BMJ Publishing Group Limited.

Asthma: epidemiology of disease control in Latin America - short review.

PubMed

Solé, Dirceu; Aranda, Carolina Sanchez; Wandalsen, Gustavo Falbo

2017-01-01

Asthma is reported as one of the most common chronic diseases in childhood, impairing the quality of life of patients and their families and incurring high costs to the healthcare system and society. Despite the development of new drugs and the availability of international treatment guidelines, asthma is still poorly controlled, especially in Latin America. Original and review articles on asthma control or epidemiology with high levels of evidence have been selected for analysis among those published in PubMed referenced journals during the last 20 years, using the following keywords: "asthma control" combined with "Latin America", " epidemiology", "prevalence", "burden", "mortality", "treatment and unmet needs", "children", "adolescents", and "infants". There was a high prevalence and severity of asthma during the period analyzed, especially in children and adolescents. Wheezing in infants was a significant reason for seeking medical care in Latin American health centers. Moreover, the frequent use of quick-relief bronchodilators and oral corticosteroids by these patients indicates the lack of a policy for providing better care for asthmatic patients, as well as poor asthma control. Among adults, studies document poor treatment and control of the disease, as revealed by low adherence to routine anti-inflammatory medications and high rates of emergency care visits and hospitalization. In conclusion, although rare, studies on asthma control in Latin America repeatedly show that patients are inadequately controlled and frequently overestimate their degree of asthma control according to the criteria used by international asthma treatment guidelines. Additional education for doctors and patients is essential for adequate control of this illness, and therefore also for reduction of the individual and social burden of asthma.

Objective To evaluate the impact of comparative performance feedback to community pharmacists on provision of professional services and the quality of patients’ medication use. Design Randomised, controlled, single-blind trial. Setting All 1833 community pharmacies in the Quebec province, Canada. Participants 1814 pharmacies not opting out and with more than 5 dispensings of the target medications during the 6-month baseline were randomised by a 2×2 factorial design to feedback first for hypertension adherence (907 control, 907 intervention) followed by randomisation for asthma adherence (791 control, 807 intervention). 1422 of 1814 pharmacies had complete information available during the follow-up for hypertension intervention (706 intervention, 716 control), and 1301 of 1598 had the follow-up information for asthma (657 intervention, 644 control). Intervention Using provincial billing data to measure performance, mailed comparative feedback reported the pharmacy-level percentage of dispensings to patients non-adherent to antihypertensive medications or overusing asthma rescue inhalers. Primary and secondary outcome measures The number of hypertension/asthma services billed per pharmacy and percentage of dispensings to non-adherent patients over the 12 months post intervention. Results Feedback on the asthma measure led to increased provision of asthma services (control 0.2, intervention 0.4, RR 1.58, 95% CI 1.02 to 2.46). However, this did not translate into reductions in patients’ overuse of rescue inhalers (control 45.5%, intervention 44.6%, RR 0.99, 95% CI 0.98 to 1.01). For non-adherence to antihypertensive medications, feedback resulted in no difference in either provision of hypertension services (control 0.7, intervention 0.8, RR 1.25, 95% CI 0.86 to 1.82) or antihypertensive treatment adherence (control 27.9%, intervention 28.0%, RR 1.0, 95% CI 0.99 to 1.00). Baseline performance did not influence results, and there was no evidence of a cumulative effect with repeated feedback. Conclusions Comparative pharmacy performance feedback increased the provision of asthma pharmacists’ services but did not improve the performance on medication-use measures. Billing data can be used to evaluate the impact of billable services rendered by pharmacists on the quality of patients’ medication use. PMID:27207626

Asthma disparities in urban environments.

PubMed

Bryant-Stephens, Tyra

2009-06-01

Asthma continues to disproportionately affect minority and low-income groups, with African American and Latino children who live in low-socioeconomic-status urban environments experiencing higher asthma morbidity and mortality than white children. This uneven burden in asthma morbidity has been ever increasing despite medical advancement. Many factors have contributed to these disparities in the areas of health care inequities, which result in inadequate treatment; poor housing, which leads to increased exposure to asthma allergens; and social and psychosocial stressors, which are often unappreciated. Interventions to reduce individual areas of disparities have had varying successes. Because asthma is a complex disease that affects millions of persons, multifaceted comprehensive interventions that combine all evidence-based successful strategies are essential to finally closing the gap in asthma morbidity.

It has been suggested that children that are exposed to a stressful environment at home have an increased susceptibility for air pollution-related asthma. The aim here was to investigate the association between air pollution exposure and asthma, and effect modification by mental health and by socio-economic status (as markers of a stressful environment). All individuals under 18 years of age in four Swedish counties during 2007 to 2010 (1.2 million people) were included. The outcome was defined as dispensing at least two asthma medications during follow up. We linked data on NO2 from an empirical land use regression to data from national registers on outcome and potential confounders. Data was analyzed with logistic regression. There was an odds ratio (OR) of 1.02 (95% Confidence Interval (CI: 1.01–1.03) for asthma associated with a 10 µg·m−3 increase in NO2. The association only seemed to be present in areas where NO2 was higher than 15 µg·m−3 with an OR of 1.09 (95% CI: 1.07–1.12), and the association seemed stronger in children with parents with a high education, OR = 1.05 (95% CI: 1.02–1.09) and OR = 1.04 (95% CI: 1.01–1.07) in children to mothers and father with a high education, respectively. The association did not seem to depend on medication history of psychiatric disorders. There was weak evidence for the association between air pollution and asthma to be stronger in neighborhoods with higher education levels. In conclusion, air pollution was associated with dispensed asthma medications, especially in areas with comparatively higher levels of air pollution, and in children to parents with high education. We did not observe support for our hypothesis that stressors linked to socio-economy or mental health problems would increase susceptibility to the effects of air pollution on the development of asthma.

Passy, V; Ermshar, C

Therapy for such obstructive pulmonary lung diseases as alveolar proteinosis, pneumonia, asthma, bronchiectasis, and cystic fibrosis, ranges from medical therapy to inhalation therapy to direct bronchoscopy and irrigation. The basic pathophysiologic feature is the retention of mucous secretions and foreign material within the lungs and therapy directed to removal of these secretions. Bronchopulmonary lavage recently has been suggested as an effective tool toward resolution of these illnesses. The otolaryngologist, who is adept in endoscopy, is asked to perform bronchoscopic procedures with washings to aid in the alleviation of these obstructive pulmonary diseases. This paper deals with the effectiveness of massive bronchopulmonary lavage in the elimination of severe chronic obstructive pulmonary lung diseases.

Monitoring asthma in childhood: symptoms, exacerbations and quality of life.

PubMed

Brand, Paul L P; Mäkelä, Mika J; Szefler, Stanley J; Frischer, Thomas; Price, David

2015-06-01

Monitoring asthma in children in clinical practice is primarily performed by reviewing disease activity (daytime and night-time symptoms, use of reliever medication, exacerbations requiring frequent use of reliever medication and urgent visits to the healthcare professional) and the impact of the disease on children's daily activities, including sports and play, in a clinical interview. In such an interview, most task force members also discuss adherence to maintenance therapy and the patients' (and parents') views and beliefs on the goals of treatment and the amount of treatment required to achieve those goals. Composite asthma control and quality of life measures, although potentially useful in research, have limited value in clinical practice because they have a short recall window and do not cover the entire spectrum of asthma control. Telemonitoring of children with asthma cannot replace face-to-face follow-up and monitoring because there is no evidence that it is associated with improved health outcomes. Copyright ©ERS 2015.

The effect of obesity, weight gain, and weight loss on asthma inception and control.

PubMed

Forno, Erick; Celedón, Juan C

2017-04-01

There is ample and growing evidence that obesity increases the risk of asthma and morbidity from asthma. Here, we review recent clinical evidence supporting a causal link between obesity and asthma, and the mechanisms that may lead to 'obese asthma'. Although in some children obesity and asthma simply co-occur, those with 'obese asthma' have increased asthma severity, lower quality of life, and reduced medication response. Underlying mechanistic pathways may include anatomical changes of the airways such as obstruction and dysanapsis, systemic inflammation, production of adipokines, impaired glucose-insulin metabolism, altered nutrient levels, genetic and epigenetic changes, and alterations in the airway and/or gut microbiome. A few small studies have shown that weight loss interventions may lead to improvements in asthma outcomes, but thus far research on therapeutic interventions for these children has been limited. Obesity increases the risk of asthma - and worsens asthma severity or control - via multiple mechanisms. 'Obese asthma' is a complex, multifactorial phenotype in children. Obesity and its complications must be managed as part of the treatment of asthma in obese children.

Asthma management self-efficacy in parents of primary school-age children.

2014-06-01

The aim of this study was to investigate asthma management self-efficacy in parents of primary school-age children with asthma and to explore possible associations between parent asthma management self-efficacy, parent and child characteristics, asthma task difficulty and asthma management responsibility. A cross-sectional descriptive survey of 113 parents was conducted to assess the level of parent asthma management self-efficacy, asthma task difficulty and confidence, asthma responsibility and socio-demographic characteristics. The findings indicate that parents had higher self-efficacy for attack prevention than attack management. Parents had higher self-efficacy for asthma management tasks that are simple, skills based and performed frequently such as medication administration and less confidence and greater difficulty with tasks associated with judgement and decision-making. Multivariate linear regression analysis identified English language, child asthma responsibility and parent education as predictors of higher asthma management self-efficacy, while an older child was associated with lower parent asthma management self-efficacy. The implications of these results for planning and targeting health education and self-management interventions for parents and children are discussed. © The Author(s) 2013.

Understanding what asthma plans mean: a linguistic analysis of terminology used in published texts.

2011-06-01

To identify from the literature what terms are used for 'asthma plans', with what meaning, and in what context(s). Linguistic analysis of a selected body of asthma literature from 1989-2009. A wide range of asthma plan terminology was evident, with terms such as 'action plans', 'self-management plans' and 'treatment plans' being applied inconsistently and synonymously. For individual patients the term 'asthma plan' can describe a clinically-determined list of prescribed medication, an agreed plan to guide self-management of changing symptoms, or a more holistic 'living with asthma' plan. In some contexts the term 'asthma plan' was also used to describe an organisational system of care, which causes further ambiguity. Within the literature, a plethora of terms is used inconsistently and with varied meaning. This is a potential, but previously unrecognised, barrier to asthma plan implementation. A taxonomy of asthma plans and a standardised definitions of terms is required.

Home-based asthma education of young low-income children and their families.

To conduct a controlled trial of a home-based education program for low-income caregivers of young children with asthma. Participants were randomized to treatment-eight weekly asthma education sessions adapted from the Wee Wheezers program (n = 49)-or usual care (n = 46). Baseline and 3- and 12-month follow-up data were gathered from caregivers and from children's medical records. Treatment was associated with less bother from asthma symptoms, more symptom-free days, and better caregiver quality of life at follow-up for children 1-3, but not those 4-6, years of age. Treatment and control groups did not differ in caregiver asthma management behavior or children's acute care utilization. This home-based asthma education program was most effective with younger children; perhaps their caregivers were more motivated to learn about asthma management. Targeting psychosocial factors associated with asthma morbidity might also enhance the efficacy of asthma education for these families.

Objective: To evaluate the general level of asthma management in urban areas of China and further promote the national asthma management plan. Methods: A multi-center, cross-sectional survey was carried out in 30 provinces of China (except for Tibet) during Oct 2015 to May 2016. It's a questionnaire-based face-to-face survey which included asthma management using peak flow meter (PFM) and pulmonary function test, medication choice of maintenance therapy and asthma education. Results: A total of 3 875 asthmatic outpatients were recruited including 2 347(60.6%) females and 1 528(39.4%) males. The mean age was (50.7±16.7) years ranging from 14 to 99. Only 10.1%(388/3 837) patients used PFM as monitoring, whereas 62.1%(2 405/3 874) patients underwent pulmonary function test during the past year. There were 57.4%(2 226/3 875) patients treated with inhaled cortical steroid plus long-acting β(2)-agonist combinations (ICS+LABA) as daily medication. 43.3%(1 661/3 836) patients were followed up by physicians. Among this population, 1 362 asthmatic outpatients were recruited, who also took part in the asthma control survey in 2007-2008 in 10 cities. In this subgroup, 17.9%(244/1 360) were tested by PFM and 66.6%(907/1 362) by pulmonary function test during last year. As to the medication, 63.1%(860/1 362) selected ICS+LABA for daily control. There were 50.4%(685/1 359) patients in the follow-up cohort by physicians. Compared to the similar survey conducted in 2007-2008, the proportion of patients with ICS+LABA regimen and follow-up by physicians were markedly higher, while the rate of PFM use did not have significant improvement. Conclusion: Although the present level of asthma management in China is still far from ideal, asthma management has improved compared to 8 years ago. Yet the use of PFM does not significantly improve. Asthma action plan and application of PFM should be further promoted to improve the level of asthma management.

A Self-Regulation Theory–Based Asthma Management Mobile App for Adolescents: A Usability Assessment

PubMed Central

2017-01-01

Background Self-regulation theory suggests people learn to influence their own behavior through self-monitoring, goal-setting, feedback, self-reward, and self-instruction, all of which smartphones are now capable of facilitating. Several mobile apps exist to manage asthma; however, little evidence exists about whether these apps employ user-centered design processes that adhere to government usability guidelines for mobile apps. Objective Building upon a previous study that documented adolescent preferences for an asthma self-management app, we employed a user-centered approach to assess the usability of a high-fidelity wireframe for an asthma self-management app intended for use by adolescents with persistent asthma. Methods Individual interviews were conducted with adolescents (ages 11-18 years) with persistent asthma who owned a smartphone (N=8). Adolescents were asked to evaluate a PDF app wireframe consisting of 76 screen shots displaying app features, including log in and home screen, profile setup, settings and info, self-management features, and graphical displays for charting asthma control and medication. Preferences, comments, and suggestions for each set of screen shots were assessed using the audio-recorded interviews. Two coders reached consensus on adolescent evaluations of the following aspects of app features: (1) usability, (2) behavioral intentions to use, (3) confusing aspects, and (4) suggestions for improvement. Results The app wireframe was generally well received, and several suggestions for improvement were recorded. Suggestions included increased customization of charts and notifications, reminders, and alerts. Participants preferred longitudinal data about asthma control and medication use to be displayed using line graphs. All participants reported that they would find an asthma management app like the one depicted in the wireframe useful for managing their asthma. Conclusions Early stage usability tests guided by government usability guidelines (usability.gov) revealed areas for improvement for an asthma self-management app for adolescents. Addressing these areas will be critical to developing an engaging and effective asthma self-management app that is capable of improving adolescent asthma outcomes. PMID:28148471

High prevalence of asthma and bronchospasm was observed during induction of anesthesia in patients with chronic suppurative otitis mMedia (CSOM) who underwent tympanomastoidectomy. Although several studies have proposed association of allergic diseases with CSOM but no consensus about it has been established. Current study was designed to determine the coincidence of asthma in CSOM patients. In a cross-sectional study, authors investigated medical records of 106 CSOM patients underwent tympanomastoidectomy, aged 15 to 65 years, and 95 controls, which were matched by age and sex. Participants were admitted to Valiasr Hospital, Tehran, Iran, from April of 2011 to March of 2013. Required information, such as demographic characteristics and history of allergic rhinitis (AR) and asthma were obtained from patients' medical records. The prevalence of AR in the CSOM group was higher than controls' group (19.8% and 15.8%, respectively) (P>0.05). Asthma prevalence was significantly higher in patients with CSOM (P=0.03) (OR=7.67, 95% CI:  0.9-62.5). No significant association was found between history of AR and chronic ear infections. However, asthma was significantly more common in CSOM patients. Current study indicates that asthma and risk of bronchospasm need particular attention in patients with CSOM underwent tympanomastoidectomy before and during anesthesia.

The research on industrial food animal production (IFAP) and asthma exacerbations in the United States has relied on small sample sizes and/or self-reported outcomes. We assessed associations of proximity to large-scale and densely stocked swine and dairy/veal IFAP with three types of asthma exacerbations: hospitalizations, emergency encounters, and oral corticosteroid (OCS) medication orders from Geisinger Clinic in Pennsylvania. We used a diagnosis code ( International Classification of Diseases, 9th Revision, Clinical Modification code 493.x) and medication orders from electronic health records to identify these exacerbations among asthma patients ( n = 35,269) from 2005-2012. We compared residential proximity to swine or dairy/veal IFAP (dichotomized as <3 miles (4.8 km) or ≥3 miles) among asthma patients with and without exacerbations and estimated odds ratios using multilevel logistic regression. In adjusted models, proximity to IFAP was associated (odds ratio (95% confidence interval)) with OCS orders (1.11 (1.04-1.19)) and hospitalizations (1.29 (1.15-1.46)), but not emergency encounters (1.12 (0.91-1.37)). This study contributes to growing evidence that IFAP may impact health, in this case clinically-documented asthma exacerbations. No prior study has evaluated the association of IFAP and clinically-documented asthma exacerbations in the United States.

Clinical applications of exhaled nitric oxide for the diagnosis and management of asthma: a consensus report.

Patients with asthma routinely exhibit elevated levels of fractionated exhaled nitric oxide (FE(NO)), and this observation has led to studies investigating FE(NO) as a potential marker of airway inflammation. FE(NO) has been shown to enhance the diagnosis of asthma, detect deterioration in control of patients with asthma, and monitor response to anti-inflammatory therapy. The aim of this work was to determine if FE(NO) measurement provides a noninvasive, well-tolerated, and standardized technique to monitor airway inflammation, and if it has the potential to complement standard asthma monitoring tools (eg, symptom diaries, control questionnaires, and pulmonary function testing) and to improve asthma control and patient outcomes. Thirteen experts in the diagnosis and treatment of asthma met to discuss the use of FE(NO) in the diagnosis and management of patients with asthma. Participants were selected by Aerocrine, a medical, technical company with headquarters in Stockholm, Sweden, in consultation with their medical education partner Cadent Medical Communications located in Irving, Texas, to represent a diversity of specialists, including both clinicians and investigators, in the fields of allergy, immunology, and pulmonology. All participants were nominally compensated for their time to attend this closed scientific roundtable discussion. The meeting was supported by an educational grant from Aerocrine. This report represents the overall consensus reached by the participants on the clinical applicability of this technique. Our understanding of asthma has expanded so that investigators are now focusing on inflammation in addition to airway obstruction and hyper-reactivity. Whereas patient history, symptoms, and pulmonary function testing can assist in diagnosing asthma, they are not direct measures of the extent of airway inflammation. Elevated FE(NO) levels have been shown to reflect airway inflammation and to occur together with other conventional markers used to detect inflammation. Studies have confirmed increased levels of FE(NO) in both adults and children with asthma. In most studies, FE(NO) was found to be elevated 2- to 3-fold compared with normal controls. There are many determinants of FE(NO) levels, however, and factors other than inflammation must be considered when FE(NO) measurement is used to diagnose and monitor asthma. FE(NO) measurement alone is not sufficient for diagnosing or monitoring asthma, but it can be a valuable addition to current clinical tools. FE(NO) measurement is a noninvasive and reproducible test that is a surrogate measure of airway inflammation in patients with asthma. The test has demonstrated utility in diagnosing and managing asthma and in predicting response to therapy and, therefore, may be an important tool to incorporate into clinical care.

Attention-deficit hyperactivity disorder (ADHD) medications are subject to abuse, misuse, and diversion. Obtaining ADHD prescriptions from multiple prescribers or filled across multiple pharmacies, known as 'doctor shopping', may reflect such unsanctioned use. We sought to create a definition of shopping behavior that differentiated ADHD medications from medications with low risk of diversion, i.e. asthma medications, and describe the incidence, frequency, and demography of shopping behavior. This was a retrospective cohort study in a pharmacy database-LRx-covering 65 % of US retail pharmacies. Subjects had ADHD or asthma medication dispensed between February 2011 and January 2012. We followed subjects for 18 months to assess the number with overlapping dispensings from different prescribers, and the number of prescribers and pharmacies involved in those dispensings. We included 4,402,464 subjects who were dispensed ADHD medications, and 6,128,025 subjects who were dispensed asthma medications. Overlapping prescriptions from two or more prescribers dispensed by three or more pharmacies was four times more frequent in the ADHD cohort than in the asthma cohort. Using this definition, ADHD medication shopping behavior was more common among experienced users than naïve users, and was most common in subjects aged 10-39 years. Among subjects who shopped, 57.4 % shopped only once (accounting for 22.4 % of episodes), and 9.2 % shopped six or more times (accounting for 42.0 % of episodes). Shoppers more often received stimulant ADHD drugs than non-stimulants. Overlapping prescriptions by different prescribers and filled at three or more pharmacies defines ADHD medication shopping. Shopping behavior is most common in adolescents and younger adults. A small proportion of shoppers is responsible for a large number of shopping episodes.

To describe and categorize contextual information relevant to patients' medical care unexpectedly volunteered to research personnel as part of a patient advocate (PA) intervention to facilitate access health care, communication with medical personnel, and self-management of a chronic disease such as asthma. We adapted a patient navigator intervention, to overcome barriers to access and communication for adults with moderate or severe asthma. Informed by focus groups of patients and providers, our PAs facilitated preparation for a visit with an asthma provider, attended the visit, confirmed understanding, and assisted with post-visit activities. During meetings with researchers, either for PA activities or for data collection, participants frequently volunteered personal and medical information relevant for achieving successful self-management that was not routinely shared with medical personnel. For this project, researchers journaled information not captured by the structured questionnaires and protocol. Using a qualitative analysis, we describe (1) researchers' journals of these unique communications; (2) their relevance for accomplishing self-management; (3) PAs' formal activities including teach-back, advocacy, and facilitating appointment making; and (4) observations of patients' interactions with the clinical practices. In 83 journals, patients' social support (83%), health (68%), and deportment (69%) were described. PA assistance with navigating the medical system (59%), teach-back (46%), and observed interactions with patient and medical staff (76%) were also journaled. Implicit were ways patients and practices could overcome barriers to access and communication. These journals describe the importance of seeking contextual and medically relevant information from all patients and, especially, those with significant morbidities, prompting patients for barriers to access to health care, and confirming understanding of medical information.

Increased air pollutant concentrations have been linked to several asthma-related outcomes in children, including respiratory symptoms, medication use, and hospital visits. However, few studies have examined effects of ultrafine particles in a pediatric population. Our primary objective was to examine the effects of ambient concentrations of ultrafine particles on asthma exacerbation among urban children and determine whether consistent treatment with inhaled corticosteroids could attenuate these effects. We also explored the relationship between asthma exacerbation and ambient concentrations of accumulation mode particles, fine particles (≤2.5 micrograms [μm]; PM2.5), carbon monoxide, sulfur dioxide, and ozone. We hypothesized that increased 1-7 day concentrations of ultrafine particles and other pollutants would be associated with increases in the relative odds of an asthma exacerbation, but that this increase in risk would be attenuated among children receiving school-based corticosteroid therapy. We conducted a pilot study using data from 3 to 10 year-old children participating in the School-Based Asthma Therapy trial. Using a time-stratified case-crossover design and conditional logistic regression, we estimated the relative odds of a pediatric asthma visit treated with prednisone (n=96 visits among 74 children) associated with increased pollutant concentrations in the previous 7 days. We re-ran these analyses separately for children receiving medications through the school-based intervention and children in a usual care control group. Interquartile range increases in ultrafine particles and carbon monoxide concentrations in the previous 7 days were associated with increases in the relative odds of a pediatric asthma visit, with the largest increases observed for 4-day mean ultrafine particles (interquartile range=2088p/cm(3); OR=1.27; 95% CI=0.90-1.79) and 7-day mean carbon monoxide (interquartile range=0.17ppm; OR=1.63; 95% CI=1.03-2.59). Relative odds estimates were larger among children receiving school-based inhaled corticosteroid treatment. We observed no such associations with accumulation mode particles, black carbon, fine particles (≤2.5μm), or sulfur dioxide. Ozone concentrations were inversely associated with the relative odds of a pediatric asthma visit. These findings suggest a response to markers of traffic pollution among urban asthmatic children. Effects were strongest among children receiving preventive medications through school, suggesting that this group of children was particularly sensitive to environmental triggers. Medication adherence alone may be insufficient to protect the most vulnerable from environmental asthma triggers. However, further research is necessary to confirm this finding. © 2013 Published by Elsevier Inc.

A diagnosis of asthma is considered an independent risk factor for chronic obstructive pulmonary disease (COPD). However, little is known about health service use patterns in patients with COPD who have a history of asthma in comparison with those without such a history, especially regarding comorbid conditions. To estimate the excess costs of COPD in patients with a history of asthma (COPD+asthma) versus those with COPD without such a history (COPD-only); to estimate excess costs attributable to inpatient care, outpatient care, medications, and community care; and to estimate excess costs attributable to comorbid conditions. We used vital statistics, inpatient and outpatient encounters, filled prescription records, and community care data of patients in British Columbia, Canada, from 1997 to 2012 to create propensity score-matched COPD+asthma and COPD-only cohorts. We calculated and compared the excess medical costs (in 2012 Canadian dollars [$]) between the two groups on the basis of billing information. Comorbidities were ascertained from the inpatient and outpatient records and were classified on the basis of major categories of the International Classification of Diseases, 10th Revision. The final sample consisted of 22,565 individuals within each group (mean age at baseline, 67.9 yr; 57.0% female; average follow-up, 4.07 yr). Excess costs of COPD+asthma were $540.7 per patient-year (PY) (95% confidence interval [CI], $301.7-$779.8; P < 0.001). Costs of medications ($657.9/PY; P < 0.001) and outpatient services ($127.6/PY; P < 0.001) were higher in COPD+asthma, but costs of hospitalizations were lower (-$271.0/PY; P = 0.002). Community care costs in the two groups were similar (P = 0.257). The excess cost of respiratory-related conditions was $856.2/PY (P < 0.001), with $552.6/PY being due to respiratory-related medications (P < 0.001); costs of all other conditions combined were lower in COPD+asthma, mainly due to lower costs of cardiovascular diseases (-$201.8/PY; P < 0.001). Patients with COPD with a previous history of asthma consume more health care resources than those with COPD alone, but there are important differences in cost components and costs attributable to comorbid conditions. Further research is required to examine whether the lower costs of cardiovascular disease in these patients is due to lower levels of related risk factors or to intrinsic differences in COPD phenotypes.

Real-world data on the benefit/risk profile of medicines is needed, particularly in patients who are ineligible for randomised controlled trials conducted for registration purposes. This paper describes the methodology and source data verification which enables the conduct of pre-licensing clinical trials of COPD and asthma in the community using the electronic medical record (EMR), NorthWest EHealth linked database (NWEH-LDB) and alert systems. Dual verification of extracts into NWEH-LDB was performed using two independent data sources (Salford Integrated Record [SIR] and Apollo database) from one primary care practice in Salford (N = 3504). A feasibility study was conducted to test the reliability of the NWEH-LDB to support longitudinal data analysis and pragmatic clinical trials in asthma and COPD. This involved a retrospective extraction of data from all registered practices in Salford to identify a cohort of patients with a diagnosis of asthma (aged ≥18) and/or COPD (aged ≥40) and ≥2 prescriptions for inhaled bronchodilators during 2008. Health care resource utilisation (HRU) outcomes during 2009 were assessed. Exacerbations were defined as: prescription for oral corticosteroids (OCS) in asthma and prescription of OCS or antibiotics in COPD; and/or hospitalisation for a respiratory cause. Dual verification demonstrated consistency between SIR and Apollo data sources: 3453 (98.6%) patients were common to both systems; 99.9% of prescription records were matched and of 29,830 diagnosis records, one record was missing from Apollo and 272 (0.9%) from SIR. Identified COPD patients were also highly concordant (Kappa coefficient = 0.98). A total of 7981 asthma patients and 4478 COPD patients were identified within the NWEH-LDB. Cohort analyses enumerated the most commonly prescribed respiratory medication classes to be: inhaled corticosteroids (ICS) (42%) and ICS plus long-acting β2-agonist (LABA) (40%) in asthma; ICS plus LABA (55%) and long-acting muscarinic antagonists (36%) in COPD. During 2009 HRU was greater in the COPD versus asthma cohorts, and exacerbation rates in 2009 were higher in patients who had ≥2 exacerbations versus ≤1 exacerbation in 2008 for both asthma (137.5 vs. 20.3 per 100 person-years, respectively) and COPD (144.6 vs. 41.0, respectively). Apollo and SIR data extracts into NWEH-LDB showed a high level of concordance for asthma and COPD patients. Longitudinal data analysis characterized the COPD and asthma populations in Salford including medications prescribed and health care utilisation outcomes suitable for clinical trial planning.

The incidence of asthma is increasing worldwide, but morbidity and mortality are decreasing, because of improvements in medical care. Although the incidence of severe perioperative bronchospasm is relatively low in asthmatics undergoing anaesthesia, when it does occur it may be life-threatening. Preoperative assessment of asthma should include a specialized medical hystory and physical examination as well as pulmonary function testing. Potential trigger agents should be identified and avoided. In many asthmatic patients treatment with systemic corticosteroids and bronchodilators is indicated to prevent the inflammation and bronchocostriction associated with endotracheal intubation. Nonetheless, acute bronchospasm can still occur, especially at induction and emergence, and should be promptly and methodically managed.

Self-reported influence of television-based direct-to-consumer advertising on patient seasonal allergy and asthma medication use: An internet survey.

Direct-to-consumer advertising (DDTCA) of medications, a marketing tool used by the pharmaceutical industry to increase patient awareness of products, affects both consumer behavior and, ultimately, physician prescribing practices. Billions of dollars are budgeted each year for DTCA, and its influence is far-reaching. However, little information is available about patient-initiated physician interactions in which television-bbased DTCA has played a role in consumer behavior. The objective of this study was to explore the influence of television-based DTCA on treatment changes in patient-initiated medication use. A 68-item survey instrument consisting of dichotomous, multiple-choice, and open-ended questions was constructed and sent to a convenience sample of US residents during 3 consecutive months ending in February 2005. The survey, which was accessed through an Internet link provided in the e-mail, was designed to capture data about patient perceptions and behaviors regarding television-based DTCA of prescription medications used for seasonal allergy and asthma as well as demographic information. Inferential and descriptive analyses were performed. Key tests included Crosstabs analysis and normal approximation to the binomial test with the z score. Surveys were sent to 2500 individuals. A total of 427 valid surveys were returned for a 17.1% response rate. Of the 402 respondents (94.1%) who stated that they had seen DTCA for seasonal allergy medication, 50 (12.4%) said they had discussed the advertised medication with their physician and 22 of those discussions (44.0%) resulted in a change in treatment. Three hundred forty-two respondents (80.1%) stated that they had viewed DTCA for prescription asthma medications, and 23 of those respondents (6.7%) said that they had discussed the brand of asthma medication viewed on television with their physician. Those discussions resulted in a change in treatment for 9 respondents (39.1%). Within th his limited, self-reported, survey sample, patient-initiated discussions with physicians regarding television-based DTCA of allergy and asthma medications resulted in a change of treatment in 44.0% and 39.1% of respondents, respectively.

Asthma prevalence and severity in low-resource communities.

The prevalence of asthma was thought to be low in most low-income countries, but several reports have indicated this is not always true. This is a narrative review of recent publications on the burden of asthma in low and middle-income countries (LMIC) and underprivileged communities from developed countries. Several studies have reported a low prevalence of asthma is LMIC, but indicate it is increasing. In the last few years, however, many surveys demonstrated this may not always be true. An analysis of the International Study for Asthma and Allergy in Childhood phase III database indicated although the prevalence of asthma among children and adolescents is higher in the developed countries, symptoms of asthma are often more severe in less affluent nations. The rate of uncontrolled asthma is also higher among underprivileged communities of developed countries. Secondary analysis of data generated by the WHO's world health survey performed among adults of 70 countries indicate symptoms of asthma are less frequent in middle-income countries and more frequent in the extremes, low income and high income. This sort of U shaped distribution suggests the disease (or syndrome) comprise more than one major phenotype related to diverse underlying mechanisms. In fact, recent reports show symptoms of asthma among the poor are associated with unhygienic living conditions, which may reduce the risk of atopy but increase the risk of nonatopic wheezing. Urbanization and exposure to air pollution also seem to contribute to an increasing prevalence severity of asthma in LMIC. Access to proper diagnosis and treatment with controller medications for asthma, specially with inhaled corticosteroids is feasible and cost-effective, reduce symptoms, health resource utilization, improves quality of life, and reduce mortality in low-resource settings. Prevalence of asthma was thought to be low in low-income countries, but several reports have indicated this is not always true. Under diagnosis, under treatment, exposure to air pollution, and unhygienic living conditions may contribute to a higher frequency and severity of symptoms of asthma among the poor. Proper diagnosis and treatment with controller medications for asthma is feasible and cost-effective in low-resource settings.

In 2006 we published our first review based on the available literature on occupational asthma in maritime environments in the "International Maritime Health" journal. Since then, we have obtained a great deal of new knowledge on asthma in seafood workers and fishermen and on the impact of exposures from sulphites preservatives, container fumigants etc. in maritime workers. This review aims to provide an update of the current knowledge base about occupational asthma in a maritime context and to provide recommendations regarding medical surveillance of workers at risk.

Health literacy and asthma.

The report "Healthy people" from the US Department of Health and Human Services defines health literacy (HL) as follows: "The degree to which individuals have the capacity to obtain, process, and understand basic health information and services needed to make appropriate health decisions." The same report identifies asthma as a public health problem of high priority. Unfortunately, impaired HL is prevalent in our society, and patients with low HL and asthma face multiple challenges as they attempt to manage their disease. Indeed, the National Asthma Education and Prevention Program's current guidelines require patients to have considerable HL and self-management skills. Numerous studies have linked inadequate literacy with poor health outcomes. Unlike many sociodemographic variables, HL can potentially be addressed in the health care setting. The purpose of this review is to raise awareness of the problem, summarize the current evidence linking HL and asthma, and offer strategies to strengthen the communication between patients and health care providers to decrease asthma health disparities. In addition, we discuss potential future directions for research in this field. Copyright © 2012 American Academy of Allergy, Asthma & Immunology. Published by Mosby, Inc. All rights reserved.

The study's objective was to determine the effectiveness of a social marketing intervention in influencing use of a targeted electronic medical record (EMR) template to document a standard asthma encounter. This quasi-randomized controlled trial used intervention groups exposed to an educational workshop on EMR documentation with embedded social marketing messages aimed at persuading behavior. Conducted in July 2009 to June 2010, participants in the study included third-year medical students. The primary outcome was the number of participants using a target EMR template. (Clinicaltrials.gov identifier: NCT01043113). A total of 155 participants randomized across eight clusters. Following the workshop, intervention groups were more likely to use the target asthma template than the control group (PR 3.97, 95% CI=1.34--11.79). At slightly over 30 days following the workshop, the intervention group continued to use the asthma template more often than the control group (PR 2.40, 95% CI=1.10--5.21). Stratifying by gender, intervention group females used the asthma template more after the interventions than control group females (PR 10.79, 95% CI=1.18--64.27). In follow-up at slightly over 30 days after the intervention, intervention group female participant asthma template use continued to be used more than control group females (PR 2.82, 95% CI=1.58--5.02). There were no significant differences in group use of asthma template use by intervention group males immediately after the intervention compared to control group males (PR 2.55, 95% CI=0.80--8.14) or similarly at slightly over 30 day follow-up (PR 2.18, 95% CI=0.74-6.42). Social marketing can effectively influence medical student use of EMR templates for clinical documentation in a controlled setting.

Background Despite national disease management plans, optimal asthma management remains a challenge in Australia. Community pharmacists are ideally placed to implement new strategies that aim to ensure asthma care meets current standards of best practice. The impact of the Pharmacy Asthma Care Program (PACP) on asthma control was assessed using a multi‐site randomised intervention versus control repeated measures study design. Methods Fifty Australian pharmacies were randomised into two groups: intervention pharmacies implemented the PACP (an ongoing cycle of assessment, goal setting, monitoring and review) to 191 patients over 6 months, while control pharmacies gave their usual care to 205 control patients. Both groups administered questionnaires and conducted spirometric testing at baseline and 6 months later. The main outcome measure was asthma severity/control status. Results 186 of 205 control patients (91%) and 165 of 191 intervention patients (86%) completed the study. The intervention resulted in improved asthma control: patients receiving the intervention were 2.7 times more likely to improve from “severe” to “not severe” than control patients (OR 2.68, 95% CI 1.64 to 4.37; p<0.001). The intervention also resulted in improved adherence to preventer medication (OR 1.89, 95% CI 1.08 to 3.30; p = 0.03), decreased mean daily dose of reliever medication (difference −149.11 μg, 95% CI −283.87 to −14.36; p = 0.03), a shift in medication profile from reliever only to a combination of preventer, reliever with or without long‐acting β agonist (OR 3.80, 95% CI 1.40 to 10.32; p = 0.01) and improved scores on risk of non‐adherence (difference −0.44, 95% CI −0.69 to −0.18; p = 0.04), quality of life (difference −0.23, 95% CI −0.46 to 0.00; p = 0.05), asthma knowledge (difference 1.18, 95% CI 0.73 to 1.63; p<0.01) and perceived control of asthma questionnaires (difference −1.39, 95% CI −2.44 to −0.35; p<0.01). No significant change in spirometric measures occurred in either group. Conclusions A pharmacist‐delivered asthma care programme based on national guidelines improves asthma control. The sustainability and implementation of the programme within the healthcare system remains to be investigated. PMID:17251316

The intervention also resulted in improved adherence to preventer medication (OR 1.89, 95% CI 1.08 to 3.30; p = 0.03), decreased mean daily dose of reliever medication (difference -149.11 microg, 95% CI -283.87 to -14.36; p=0.03), a shift in medication profile from reliever only to a combination of preventer, reliever with or without long-acting beta agonist (OR 3.80, 95% CI 1.40 to 10.32; p=0.01) and improved scores on risk of non-adherence (difference -0.44, 95% CI -0.69 to -0.18; p=0.04), quality of life (difference -0.23, 95% CI -0.46 to 0.00; p=0.05), asthma knowledge (difference 1.18, 95% CI 0.73 to 1.63; p<0.01) and perceived control of asthma questionnaires (difference -1.39, 95% CI -2.44 to -0.35; p<0.01). No significant change in spirometric measures occurred in either group. A pharmacist-delivered asthma care programme based on national guidelines improves asthma control. The sustainability and implementation of the programme within the healthcare system remains to be investigated.

Entry to the Australian Defence Force (ADF) for candidates with asthma has recently changed. This article summarises the ADF entry standards for candidates with asthma. It also explains the role of general practitioners in the safe and smooth transition to the military training environment for patients with asthma. Candidates with mild asthma may be considered for entry to the ADF subject to certain criteria which includes normal spirometry and negative bronchial provocation testing. If a candidate with asthma is assessed as fit to enter the ADF, they will need to present to their GP before entry to ensure they are prepared. Assistance from the GP in providing the patient with appropriate Asthma Action Plans, prescriptions, and medications is required to ensure continuity of care during what is often a challenging transition to military life.

Cleaning work and professional use of certain cleaning products have been associated with asthma, but respiratory effects of nonprofessional home cleaning have rarely been studied. To investigate the risk of new-onset asthma in relation to the use of common household cleaners. Within the follow-up of the European Community Respiratory Health Survey in 10 countries, we identified 3,503 persons doing the cleaning in their homes and who were free of asthma at baseline. Frequency of use of 15 types of cleaning products was obtained in a face-to-face interview at follow-up. We studied the incidence of asthma defined as physician diagnosis and as symptoms or medication usage at follow-up. Associations between asthma and the use of cleaning products were evaluated using multivariable Cox proportional hazards or log-binomial regression analysis. The use of cleaning sprays at least weekly (42% of participants) was associated with the incidence of asthma symptoms or medication (relative risk [RR], 1.49; 95% confidence interval [CI], 1.12-1.99) and wheeze (RR, 1.39; 95% CI, 1.06-1.80). The incidence of physician-diagnosed asthma was higher among those using sprays at least 4 days per week (RR, 2.11; 95% CI, 1.15-3.89). These associations were consistent for subgroups and not modified by atopy. Dose-response relationships (P < 0.05) were apparent for the frequency of use and the number of different sprays. Risks were predominantly found for the commonly used glass-cleaning, furniture, and air-refreshing sprays. Cleaning products not applied in spray form were not associated with asthma. Frequent use of common household cleaning sprays may be an important risk factor for adult asthma.

Adherence to daily inhaled corticosteroid therapy is a key determinant of asthma control. Therefore, improving adherence to inhaled corticosteroids is the most effective method through which healthcare providers can help children with uncontrolled asthma. However, identifying non-adherent patients is difficult, and electronic monitoring is the only reliable method to assess adherence. (Non-)adherence is a complex behavioural process influenced by many interacting factors. Intentional barriers to adherence are common; driven by illness perceptions and medication beliefs, patients and parents deliberately choose not to follow the doctor's recommendations. Common non-intentional barriers are related to family routines, child-raising issues, and to social issues such as poverty. Effective interventions improving adherence are complex, because they take intentional and non-intentional barriers to adherence into account. There is evidence that comprehensive, guideline-based asthma self-management programmes can be successful, with excellent adherence and good asthma control. Patient-centred care focused on healthcare provider-patient/parent collaboration is the key factor determining the success of guided self-management programmes. Such care should focus on shared decision-making as this has been shown to improve adherence and healthcare outcomes. Current asthma care falls short because many physicians fail to adhere to asthma guidelines in their diagnostic approach and therapeutic prescriptions, and because of the lack of application of patient-centred health care. Increased awareness of the importance of patient-centred communication and increased training in patient-centred communication skills of undergraduates and experienced attending physicians are needed to improve adherence to daily controller therapy and asthma control in children with asthma. © 2015 John Wiley & Sons A/S.

Rationale: Despite significant advances in knowledge of the genetic architecture of asthma, specific contributors to the variability in the burden between populations remain uncovered. Objectives: To identify additional genetic susceptibility factors of asthma in European American and African American populations. Methods: A phenotyping algorithm mining electronic medical records was developed and validated to recruit cases with asthma and control subjects from the Electronic Medical Records and Genomics network. Genome-wide association analyses were performed in pediatric and adult asthma cases and control subjects with European American and African American ancestry followed by metaanalysis. Nominally significant results were reanalyzed conditioning on allergy status. Measurements and Main Results: The validation of the algorithm yielded an average of 95.8% positive predictive values for both cases and control subjects. The algorithm accrued 21,644 subjects (65.83% European American and 34.17% African American). We identified four novel population-specific associations with asthma after metaanalyses: loci 6p21.31, 9p21.2, and 10q21.3 in the European American population, and the PTGES gene in African Americans. TEK at 9p21.2, which encodes TIE2, has been shown to be involved in remodeling the airway wall in asthma, and the association remained significant after conditioning by allergy. PTGES, which encodes the prostaglandin E synthase, has also been linked to asthma, where deficient prostaglandin E2 synthesis has been associated with airway remodeling. Conclusions: This study adds to understanding of the genetic architecture of asthma in European Americans and African Americans and reinforces the need to study populations of diverse ethnic backgrounds to identify shared and unique genetic predictors of asthma.

Objective Whether or not depression affects the control or severity of asthma is unclear. We performed a cluster analysis of asthma patients with depressive symptoms to clarify their characteristics. Methods and subjects Multiple medical institutions in Niigata Prefecture, Japan, were surveyed in 2014. We recorded the age, disease duration, body mass index (BMI), medications, and surveyed asthma control status and severity, as well as depressive symptoms and adherence to treatment using questionnaires. A hierarchical cluster analysis was performed on the group of patients assessed as having depression. Results Of 2,273 patients, 128 were assessed as being positive for depressive symptoms (DS[+]). Thirty-three were excluded because of missing data, and the remaining 95 DS[+] patients were classified into 3 clusters (A, B, and C). The patients in cluster A (n=19) were elderly, had severe, poorly controlled asthma, and demonstrated possible adherence barriers; those in cluster B (n=26) were elderly with a low BMI and had no significant adherence barriers but had severe, poorly controlled asthma; and those in cluster C (n=50) were younger, with a high BMI, no significant adherence barriers, well-controlled asthma, and few were severely affected. The scores for depressive symptoms were not significantly different between clusters. Conclusion About half of the patients in the DS[+] group had severe, poorly controlled asthma, and these clusters were able to be distinguished by their ASK-12 score, which reflects adherence barriers. The control status and severity of asthma may also be related to the age, disease duration, and BMI in the DS[+] group.

Few studies have assessed the relationships between xerostomia and the use of inhaled corticosteroids (ICS). The main objective of this study was to investigate the prevalence of xerostomia in a respiratory outpatient clinic and its relationship with bronchial asthma and ICS use. A cross-sectional observational study of patients recruited in an outpatient setting divided them according to previous diagnoses of bronchial asthma. Data about pulmonary function, concomitant medication, medical comorbidities, Xerostomia Inventory test (XI test), and the degree of asthma control by ACT (asthma control test) were collected for each patient. A linear regression model was applied, using the XI score as dependent variable and the ACT score as independent variable. The 57 patients were divided into asthmatics (40 patients, 70.2%) and control group without asthma (17, 29.8%). The prevalence of xerostomia was 87.7% (50 patients), with no differences between the study groups or current dose of ICS. In the asthmatic group, patients with uncontrolled asthma had worse XI scores than those with partially or totally controlled asthma (30.43 ± 8.71 vs. 24.92 ± 8.08; P < 0.05). In a logistic regression model, the XI test was significantly associated to ACT scores with a moderately strong correlation (r = 0.55; P = 0.005) after adjusting for the current daily dose of ICS. Xerostomia is a common symptom in the ambulatory setting. There is a moderate relationship between the degree of asthma control and the severity of xerostomia. © 2014 John Wiley & Sons A/S.

Paterson, C; Britten, N

BACKGROUND: The 1993 chronic disease management contract encourages United Kingdom general practices to implement a standardised package of care with an emphasis on regular visits to an asthma clinic. AIM: To explore the views of people with asthma about the organisation of asthma care in general practice. METHOD: Semi-structured interviews with 20 patients registered with one practice with a nurse-run asthma clinic. The sample was selected to provide people with a wide range of ages and disease severity, and included parents of children. RESULTS: The age range of the interviewees was five to 87 years (parents of children were interviewed) and half of the interviewees had attended the asthma clinic at some time. In describing how they managed their asthma, people identified their medical care alongside other important factors, such as avoiding smoking and pollution, and a decision to seek medical help was made in the context of all of life's other priorities. People expressed diverse views about the organisation of care, describing how their needs changed over time and how they balanced up several factors in deciding what was best for them. These factors were encompassed by four themes: the accessibility of care, severity of asthma and dealing with uncertainty, self-knowledge and self-management, and expert knowledge and therapeutic relationships. Interviewees were evenly split between wishing to be seen regularly in the clinic and wishing only to attend when needing help. CONCLUSION: Patients required asthma services that allow individual choice and flexibility, and eight service objectives were identified that would cover most people's needs. PMID:10897514

To assess clinical documentation variations across health care institutions using different electronic medical record systems and investigate how they affect natural language processing (NLP) system portability. Birth cohorts from Mayo Clinic and Sanford Children's Hospital (SCH) were used in this study (n = 298 for each). Documentation variations regarding asthma between the 2 cohorts were examined in various aspects: (1) overall corpus at the word level (ie, lexical variation), (2) topics and asthma-related concepts (ie, semantic variation), and (3) clinical note types (ie, process variation). We compared those statistics and explored NLP system portability for asthma ascertainment in 2 stages: prototype and refinement. There exist notable lexical variations (word-level similarity = 0.669) and process variations (differences in major note types containing asthma-related concepts). However, semantic-level corpora were relatively homogeneous (topic similarity = 0.944, asthma-related concept similarity = 0.971). The NLP system for asthma ascertainment had an F-score of 0.937 at Mayo, and produced 0.813 (prototype) and 0.908 (refinement) when applied at SCH. The criteria for asthma ascertainment are largely dependent on asthma-related concepts. Therefore, we believe that semantic similarity is important to estimate NLP system portability. As the Mayo Clinic and SCH corpora were relatively homogeneous at a semantic level, the NLP system, developed at Mayo Clinic, was imported to SCH successfully with proper adjustments to deal with the intrinsic corpus heterogeneity. © The Author 2017.

Whether Web-based technologies can improve disease self-management is uncertain. My Asthma Portal (MAP) is a Web-based self-management support system that couples evidence-based behavioral change components (self-monitoring of symptoms, physical activity, and medication adherence) with real-time monitoring, feedback, and support from a nurse case manager. The aim of this study was to compare the impact of access to a Web-based asthma self-management patient portal linked to a case-management system (MAP) over 6 months compared with usual care on asthma control and quality of life. A multicenter, parallel, 2-arm, pilot, randomized controlled trial was conducted with 100 adults with confirmed diagnosis of asthma from 2 specialty clinics. Asthma control was measured using an algorithm based on overuse of fast-acting bronchodilators and emergency department visits, and asthma-related quality of life was assessed using the Mini-Asthma Quality of Life Questionnaire (MAQLQ). Secondary mediating outcomes included asthma symptoms, depressive symptoms, self-efficacy, and beliefs about medication. Process evaluations were also included. A total of 49 individuals were randomized to MAP and 51 to usual care. Compared with usual care, participants in the intervention group reported significantly higher asthma quality of life (mean change 0.61, 95% CI 0.03 to 1.19), and the change in asthma quality of life for the intervention group between baseline and 3 months (mean change 0.66, 95% CI 0.35 to 0.98) was not seen in the control group. No significant differences in asthma quality of life were found between the intervention and control groups at 6 (mean change 0.46, 95% CI -0.12 to 1.05) and 9 months (mean change 0.39, 95% CI -0.2 to 0.98). For poor control status, there was no significant effect of group, time, or group by time. For all self-reported measures, the intervention group had a significantly higher proportion of individuals, demonstrating a minimal clinically meaningful improvement compared with the usual care group. This study supported the use of MAP to enhance asthma quality of life but not asthma control as measured by an administrative database. Implementation of MAP beyond 6 months with tailored protocols for monitoring symptoms and health behaviors as individuals' knowledge and self-management skills improve may result in long-term gains in asthma control.

Rationale: Recent U.S. data suggest an increased risk of work-related asthma among health care workers, yet only a few specific determinants have been elucidated. Objectives: To evaluate associations of asthma prevalence with occupational exposures in a cross-sectional survey of health care professionals. Methods: A detailed questionnaire was mailed to a random sample (n = 5,600) of all Texas physicians, nurses, respiratory therapists, and occupational therapists with active licenses in 2003. Information on asthma symptoms and nonoccupational asthma risk factors obtained from the questionnaire was linked to occupational exposures derived through an industry-specific job-exposure matrix. Measurements: There were two a priori defined outcomes: (1) physician-diagnosed asthma with onset after entry into health care (“reported asthma”) and (2) “bronchial hyperresponsiveness–related symptoms,” defined through an 8-item symptom-based predictor. Main Results: Overall response rate was 66%. The final study population consisted of 862 physicians, 941 nurses, 968 occupational therapists, and 879 respiratory therapists (n = 3,650). Reported asthma was associated with medical instrument cleaning (odds ratio [OR], 2.22; 95% confidence interval [CI], 1.34–3.67), general cleaning (OR, 2.02; 95% CI, 1.20–3.40), use of powdered latex gloves between 1992 and 2000 (OR, 2.17; 95% CI, 1.27–3.73), and administration of aerosolized medications (OR, 1.72; 95% CI, 1.05–2.83). The risk associated with latex glove use was not apparent after 2000. Bronchial hyperresponsiveness–related symptoms were associated with general cleaning (OR, 1.63; 95% CI, 1.21–2.19), aerosolized medication administration (OR, 1.40; 95% CI, 1.06–1.84), use of adhesives on patients (OR, 1.65; 95% CI, 1.22–2.24), and exposure to a chemical spill (OR, 2.02; 95% CI, 1.28–3.21). Conclusions: The contribution of occupational exposures to asthma in health care professionals is not trivial, meriting both implementation of appropriate controls and further study. PMID:17185646

Asthma is a chronic airway disease that can be difficult to manage, resulting in poor outcomes and high costs. Asthma action plans assist patients with self-management, but provider compliance with this recommendation is limited in part because of guideline complexity. This project aimed to embed an electronic asthma action plan decision support tool (eAAP) into the medical record to streamline evidence-based guidelines for providers at the point of care, create individualized patient handouts, and evaluate effects on disease outcomes. eAAP development occurred in 4 phases: web-based prototype creation, multidisciplinary team engagement, pilot, and system-wide dissemination. Medical record and hospital billing data compared frequencies of asthma exacerbations before and after eAAP receipt with matched controls. Between December 2012 and September 2014, 5174 patients with asthma (∼10%) received eAAPs. Results showed an association between eAAP receipt and significant reductions in pediatric asthma exacerbations, including 33% lower odds of requiring oral steroids (P < .001), compared with controls. Equivalent adult measures were not statistically significant. This study supports existing evidence that patient self-management plays an important role in reducing asthma exacerbations. We show the feasibility of leveraging technology to provide guideline-based decision support through an eAAP, addressing known challenges of implementation into routine practice. © Copyright 2015 by the American Board of Family Medicine.

Validation of the Asthma Illness Representation Scale-Spanish (AIRS-S).

2010-05-01

To expand knowledge surrounding parental illness representations (IRs) of their children's asthma, it is imperative that culturally appropriate survey instruments are developed and validated for use in clinical and research settings. The Asthma Illness Representation Scale (AIRS) provides a structured assessment of the key components of asthma IRs, allowing the health care provider (HCP) to quickly identify areas of discordance with the professional model of asthma management. The English AIRS was developed and validated among a geographically and ethnically diverse sample. The authors present the validation results of the AIRS-S (Spanish) from a sample of Mexican and Puerto Rican parents. The AIRS was translated and back translated per approved methodologies. Factor analysis, internal reliability, external validity, and 2-week test-retest reliability (on a subsample) were carried out and results compared with the validated English version. Data were obtained from 80 Spanish-speaking Mexican and Puerto Rican parents of children with asthma. The sample was recruited from two school-based health centers and a free medical clinic in Phoenix, Arizona, and a hospital-based asthma clinic in Bronx, New York. The original Nature of Asthma Symptoms, Facts About Asthma, and Attitudes Towards Medication Use subscales emerged. Remaining factors were a mixture of items with no coherent or theoretical distinction between them. Interpretation of results is limited due to not meeting the minimum requirement of 5 observations/item. Cronbach's alpha coefficients for the total score (alpha = .77) and majority of subscales (alpha range = .53-.77) were acceptable and consistent with the English version. Parental reports of a positive relationship with the HCP significantly predicted AIRS scores congruent with the professional model; longer asthma duration was associated with beliefs aligned with the lay model; and AIRS scores congruent with the professional model were related to lower asthma severity. Stability in AIRS-S scores over 2 weeks was demonstrated. The AIRS-S is a culturally appropriate instrument that can be used by HCPs to ascertain Spanish-speaking parents' asthma illness beliefs and assess discordance with the professional model of asthma management. This information can be used by the HCP when discussing parent's asthma management strategies for their children during clinical encounters.

Environmental Causes of Asthma.

PubMed

Cockcroft, Donald W

2018-02-01

Environmental factors which cause asthma are those that induce airway inflammation with eosinophils (more common) or neutrophils along with airway hyperresponsiveness (AHR). The most common of these (indeed the most common cause of asthma) are IgE-mediated inhalant allergen exposures. Allergen-induced AHR and inflammation are both associated with the allergen-induced late asthmatic response (LAR). Although allergens were previously recognized only as causes of symptoms and bronchoconstriction in asthmatics, we now appreciate them as causes of the fundamental pathophysiologic features of asthma. Low-molecular-weight chemical sensitizers, causes of occupational asthma, also cause asthma in a manner analogous to allergen. Acute irritant-induced asthma (reactive airways dysfunction syndrome) following a very heavy irritant exposure and chronic irritant-induced asthma following repeated high exposures can also induce persistent or permanent changes (inflammation and AHR) consistent with asthma. Textile dust exposure produces a different form of airway disease (byssinosis) which is less frequently observed currently. Environmental exposure to tobacco smoke facilitates the development of asthma in children. Personal smoking and environmental air pollution have an inconsistent and likely generally small effect in causing asthma. Thieme Medical Publishers 333 Seventh Avenue, New York, NY 10001, USA.

Effects of flow sheet implementation on physician performance in the management of asthmatic patients.

Ruoff, Gary

2002-01-01

This project focused on increasing compliance, in a large family practice group, with quality indicators for the management of asthma. The objective was to determine if use of a flow sheet incorporating the Global Initiative for Asthma (GINA) guidelines could improve compliance with those guidelines if the flow sheet was placed in patients' medical records. After review and selection of 14 clinical quality indicators, physicians in the practice implemented a flow sheet as an intervention. These flow sheets were inserted into the records of 122 randomly selected patients with asthma. Medical records were reviewed before the flow sheets were placed in the records, and again approximately 6 months later, to determine if there was a change in compliance with the quality indicators. Improvement of documentation was demonstrated in 13 of the 14 quality indicators. The results indicate that compliance with asthma management quality indicators can improve with the use of a flow sheet.

The German National Program for Disease Management Guidelines, which is being operated under the auspices of the German Medical Association (GMA), the Association of the Scientific Medical Societies (AWMF) and the National Association of Statutory Health Insurance Physicians (NASHIP), provides a conceptual basis for the disease management of prioritized healthcare aspects. The main objective of the program is to establish consensus of the medical professions on key recommendations covering all sectors of healthcare provision and facilitating the coordination of care for the individual patient through time and across interfaces. Within the scope of this program, the Scientific Medical Societies concerned with the prevention, diagnosis, treatment and rehabilitation of asthma in children, adolescents and adults have reached consensus on the core contents for a National Disease Management Guideline for Asthma. This consensus was reached by applying formal techniques and on the basis of the adaptation of recommendations from existing guidelines with high quality standards in methodology and reporting, and information from evidence reports.

Understanding the magnitude of the economic impact of an illness on society is fundamental to planning and implementing relevant policies. South Korea operates a compulsory universal health insurance system providing favorable conditions for evaluating the nationwide economic burden of illnesses. The aim of this study was to estimate the economic costs of asthma imposed on Korean society. The Korean National Health Insurance claims database was used for determining the health care services provided to asthma patients defined as having at least one inpatient or outpatient claim(s) with a primary diagnosis of asthma in 2008. Both direct and indirect costs were included. Direct costs were those associated directly with treatment, medication, and transportation. Indirect costs were assessed in terms of the loss of productivity in asthma patients and their caregivers and consisted of morbidity cost, mortality cost, and caregivers' time cost. The estimated cost for 2,273,290 asthma patients in 2008 was $831 million, with an average per capita cost of $336. Among the cost components, outpatient and medication costs represented the largest cost burden. Although the costs for children accounted for the largest proportion of the total cost, the per capita cost was highest among patients ≥50 years old. The economic burden of asthma in Korea is considerable. Considering that the burden will increase with the rising prevalence, implementation of effective national prevention approaches aimed at the appropriate target populations is imperative.

In the strategies to prevent asthma exacerbations, allergic asthma needs specific treatment.

2015-04-01

No generally accepted definition of asthma exacerbation is thus far available, though in 2012 an expert committee endorsed by the National Institute of Health proposed such definition as "a worsening of asthma requiring the use of systemic corticosteroids to prevent a serious outcome". Graham and Eid reviewed the impact of asthma exacerbations, and noted that, analysing the outcomes with existing treatments, many patients with asthma remain symptomatic and experience exacerbations. This requires the introduction of new strategies to more effectively reduce the exacerbation risk, based on correct diagnosis, stopping smoking, correct inhaler technique, consistent adherence, weight management, and gaining control with the addition of medication". Indeed, as allergic asthma is the most common form, a specific approach by allergen immunotherapy should receive more attention. Actually, the efficacy of immunotherapy in allergic asthma, by the subcutaneous or the sublingual route, is supported by robust meta-analyses. The most important allergen source causing asthma is the house dust mite, but an increasing role for molds is apparent due to the ongoing climate change.

The present study examined the impact of asthma-specific thought intrusion (TI) and thought suppression (TS) on two cognitive-affective variables (self-focused attention and fear of negative evaluation) among adolescents and young adults (AYAs) diagnosed with childhood-onset asthma. Participants were 290 AYAs who completed assessment questionnaires and participated in a written exercise electronically. Asthma-TI and TS were reported by participants following participation in a writing assignment. Asthma-TI was associated with increased private, public, and social anxiety self-focused attention, and greater fear of negative evaluation. Interestingly, asthma-TS was not associated with these same outcome variables. Findings suggest illness-specific cognitions are associated with cognitive-affective variables and it may be important to assess for illness-specific intrusive thoughts following asthma-focused medical appointments. Additionally, findings suggest the importance of assessing asthma-TI and TS separately in order to better understand thoughts about health and psychological functioning.

Phenotype-Driven Therapeutics in Severe Asthma.

Inhaled corticosteroids are the mainstay of asthma treatment using a step-up approach with incremental dosing and additional controller medications in order to achieve symptom control and prevent exacerbations. While most patients respond well to this treatment approach, some patients remain refractory despite high doses of inhaled corticosteroids and a long-acting β-agonist. The problem lies in the heterogeneity of severe asthma, which is further supported by the emergence of severe asthma phenotypes. This heterogeneity contributes to the variability in treatment response. Randomized controlled trials involving add-on therapies in poorly controlled asthma have challenged the idea of a "one size fits all" approach targeting specific phenotypes in their subject selection. This review discusses severe asthma phenotypes from unbiased clustering approaches and the most recent scientific evidence on novel treatments to provide a guide in personalizing severe asthma treatment.

Background: Although perimenstrual asthma (PMA) has been associated with severe and difficult-to-control asthma, it remains poorly characterized and understood. The objectives of this study were to identify clinical, demographic, and inflammatory factors associated with PMA and to assess the association of PMA with asthma severity and control. Methods: Women with asthma recruited to the National Heart, Lung, and Blood Institute Severe Asthma Research Program who reported PMA symptoms on a screening questionnaire were analyzed in relation to basic demographics, clinical questionnaire data, immunoinflammatory markers, and physiologic parameters. Univariate comparisons between PMA and non-PMA groups were performed. A severity-adjusted model predicting PMA was created. Additional models addressed the role of PMA in asthma control. Results: Self-identified PMA was reported in 17% of the subjects (n = 92) and associated with higher BMI, lower FVC % predicted, and higher gastroesophageal reflux disease rates. Fifty-two percent of the PMA group met criteria for severe asthma compared with 30% of the non-PMA group. In multivariable analyses controlling for severity, aspirin sensitivity and lower FVC % predicted were associated with the presence of PMA. Furthermore, after controlling for severity and confounders, PMA remained associated with more asthma symptoms and urgent health-care utilization. Conclusions: PMA is common in women with severe asthma and associated with poorly controlled disease. Aspirin sensitivity and lower FVC % predicted are associated with PMA after adjusting for multiple factors, suggesting that alterations in prostaglandins may contribute to this phenotype.

To investigate the association of ethnicity with objectively, electronically measured adherence to inhaled corticosteroids (ICS) in a multicultural population of children with asthma in the city of Amsterdam. The study was designed as a prospective, observational multicenter study in which adherence to ICS and potential risk factors for adherence to ICS were measured in a cohort of Moroccan and native Dutch children with asthma. Electronic adherence measurements were performed for 3 months per patient using a Real Time Medication Monitoring (RTMM) system. Ethnicity and other potential risk factors, such as socio-economic status, asthma control and parental medication beliefs, were extracted from medical records or parent interviews. The association between adherence and ethnicity was analysed using multivariate linear regression analysis. A total of 90 children (aged 1-11 years) were included in the study and data of 87 children were used for analysis. Average adherence to ICS was 49.3 %. Native Dutch children showed higher adherence to ICS than Moroccan children (55.9 vs. 42.5 %, respectively; p = 0.044, univariate analysis). After correction for confounders (>3 annual visits to the paediatric outpatient clinic, regular use of a spacer during inhalation), the final regression model showed that ethnicity was independently associated with adherence (p = 0.028). In our Western European population of inner city children with asthma, poor adherence to ICS was a serious problem, and even somewhat more so in ethnic minorities. Paediatricians involved in asthma treatment should be aware of these cultural differences in medication-taking behaviour, but further studies are needed to elucidate the causal mechanism.

Objectives Asthma is the most prevalent chronic disease among children enrolled in Medicaid. This study measured real-world adherence and outcomes after an initial prescription for inhaled corticosteroid therapy in a multi-state Medicaid population. Methods We conducted a retrospective study among Medicaid-enrolled children aged 5–12 years with asthma in 14 southern states using 2007 Medicaid Analytic eXtract file claims data to assess adherence and outcomes over the 3 months following an initial prescription drug claim for inhaled corticosteroids (ICS-Rx). Adherence was measured by the long-term controller-to-total asthma drug claims ratio. Results Only one-third of children (33.4%) with an initial ICS-Rx achieved a controller-to-total drug ratio >0.5 over the next 90 days. Children for whom long-term control drugs represented less than half of their total asthma drug claims had a 21% higher risk of emergency department (ED) visit (adjusted odds ratio (AOR) 1.21 [95% CI 1.14, 1.27]), and a 70% higher risk of hospital admission (AOR 1.70 [95% CI 1.45, 1.98]) than those with a controller-to-total asthma drug ratio >0.5. Conclusion Real-world adherence to long-term controller medications is quite low in this racially diverse, low-income segment of the population, despite Medicaid coverage of medications. Adherence to long-term controller therapy had a measurable impact on real-world outcomes. Medicaid programs are a potential surveillance system for both medication adherence and ED utilization.

This article offers a risk assessment of bronchial asthma development in children with atopic dermatitis by applying fuzzy-set theory to accumulated statistical data. It is shown that with a view to executing the said task one should exercise a complex approach involving factors such as "IgE level", "existence of obstructions" and "burdened bronchial asthma heredity of immediate relatives". The obtained results will assist in making adequate and well-informed medical decisions as well as facilitate the decrease of the risk of developing bronchial asthma in children with atopic dermatitis.

Asthma, a disease of attacks and remission, continues to account for substantial morbidity and direct economic costs. Numerous studies--epidemiologic, toxicologic and clinical--present evidence for a broad spectrum of environmental risk factors associated with asthma. This review summarizes current thinking on a subset of these factors. Knowledge of potential environmental determinants of asthma is important to both the patient and healthcare professional in the application of multiple modalities of medical and environmental intervention for management of the development, and exacerbation of this chronic inflammatory disorder of the airways.

Asthma in the United States: burden and current theories.

PubMed

Redd, Stephen C

2002-08-01

Asthma has emerged as a major public health problem in the United States over the past 20 years. Currently, nearly 15 million Americans have asthma, including almost 5 million children. The number of asthma cases has more than doubled since 1980. Approximately 5,500 persons die from asthma each year, and rates have increased over the past 20 years. Rates of death, hospitalization, and emergency department visits are 2-3 times higher among African Americans than among white Americans. The costs of asthma have also increased to 12.7 billion dollars in 1998. Both lifestyle and environmental hypotheses have been invoked to explain the increase in asthma prevalence. Several studies have examined the relationship of obesity and asthma and found associations suggesting that obesity predisposes to the development of asthma. Some studies have found that day care attendance and having older siblings protect against the development of asthma. This observation has led investigators to hypothesize that increased exposure to microbial agents might protect against asthma (the hygiene hypothesis). Environmental exposures found to predispose to asthma include house dust mite allergen and environmental tobacco smoke. Although current knowledge does not permit definitive conclusions about the causes of asthma onset, better adherence to current recommendations for medical therapy and environmental management of asthma would reduce the burden of this disease.

Management of asthma: the essentials of good clinical practice.

Asthma is a condition that affects all countries worldwide. It is a chronic, disabling condition that diminishes the quality of life and the economic prosperity of those who live with it. The majority of persons living with asthma are from developing countries. Asthma management necessitates long-term treatment that is expensive, making it less accessible to poor people. The cost of medications is the key factor preventing people living with asthma from having access to care that has the potential to relieve their suffering, improve their quality of life and enhance their economic status. Asthma is a disease caused by environmental exposures. Genetic factors predispose certain people to developing asthma once they are exposed to the causative agents, and certain factors can trigger symptomatic episodes of asthma in those who have already developed the disease. Certain clinical characteristics differentiate asthma from other chronic lung conditions. The most important of these is that the symptoms and functional disability caused by asthma vary from one occasion to another. In those with less severe asthma, they may be present on some occasions and not others; in those with more severe asthma, their degree of severity varies from one time to another.

New Zealand (NZ) and Australia (AU) have similarly high asthma prevalence; both have universal public health systems, but different criteria for subsidized medicines. We explored differences in asthma management and asthma-related outcomes between these countries. A web-based survey was administered in AU (2012) and NZ (2013) to individuals aged ≥16 years with current asthma, drawn randomly from web-based panels, stratified by national population proportions. Symptom control was assessed with the Asthma Control Test (ACT). Healthcare utilization was assessed from reported urgent doctor/hospital visits in the previous year. NZ (n = 537) and Australian (n = 2686) participants had similar age and gender distribution. More NZ than Australian participants used inhaled corticosteroid (ICS)-containing medication (68.8% vs 60.9%; P = 0.006) but ICS/long-acting β 2 -agonist (LABA) constituted 44.4% of NZ and 81.5% of Australian total ICS use (P < 0.0001). Adherence was higher with ICS/LABA than ICS-alone (P < 0.0001), and higher in NZ than in AU (P < 0.0001). ACT scores were similar (P = 0.41), with symptoms well controlled in 58.6% and 54.4% participants, respectively. More NZ participants reported non-urgent asthma reviews (56.6% vs 50.4%; P = 0.009). Similar proportions had urgent asthma visits (27.9% and 28.6%, respectively, P = 0.75). This comparison, which included the first nationally representative data for asthma control in NZ, showed that poorly controlled asthma is common in both NZ and AU, despite subsidized ICS-containing medications. The greater use of ICS-alone in NZ relative to ICS/LABA does not appear to have compromised population-level asthma outcomes, perhaps due to better adherence in NZ. Different ICS/LABA subsidy criteria and different patient copayments may also have contributed to these findings. © 2017 Asian Pacific Society of Respirology.

Adolescents with asthma are at risk of poor outcomes and are traditionally difficult to reach. To examine adolescents' use of and asthma outcomes associated with smartphone- vs paper-based asthma action plans (AAPs). We conducted a 6-month randomized clinical trial with adolescents (12-17 years old) with persistent asthma. Participants used their respective smartphone or paper AAPs for medication instructions and peak flow or asthma symptoms logging. AAP use was measured electronically for smartphone users and via mail-in diaries for the paper group. Changes in Asthma Control Test (ACT) and self-efficacy scores were examined. Thirty-four adolescents participated in this study (median age, 15.4 years). Participants were mostly African American (62%) with state-issued insurance (71%). Adolescents in the smartphone group accessed the AAP a median of 12.17 times per week or 4.36 days per week but only recorded medications or symptoms and peak flow data in the electronic diary a median of 10 days per month during the 6-month period. Participants in the paper group recorded data a median of 23.5 days per month on their paper diaries. Overall, there were no changes in ACT and self-efficacy scores between groups. Adolescents with uncontrolled asthma (baseline ACT score ≤19) had an improvement in ACT for the smartphone group (before, 11; after, 20) ([P = .04) compared with no change in the paper group (before, 17; after, 17) (P = .64). Adolescent satisfaction with the application was high, with 100% stating they would recommend the smartphone AAP to a friend. Adolescents were frequent and highly satisfied users of the smartphone AAP with a subset of participants with uncontrolled asthma demonstrating possible clinical benefit. Findings suggest a need for larger-scale studies to determine the effectiveness of smartphone-based AAPs among high-risk patients with asthma. clinicaltrials.gov Identifier: NCT02091869.

2017-02-01

Self-regulation theory suggests people learn to influence their own behavior through self-monitoring, goal-setting, feedback, self-reward, and self-instruction, all of which smartphones are now capable of facilitating. Several mobile apps exist to manage asthma; however, little evidence exists about whether these apps employ user-centered design processes that adhere to government usability guidelines for mobile apps. Building upon a previous study that documented adolescent preferences for an asthma self-management app, we employed a user-centered approach to assess the usability of a high-fidelity wireframe for an asthma self-management app intended for use by adolescents with persistent asthma. Individual interviews were conducted with adolescents (ages 11-18 years) with persistent asthma who owned a smartphone (N=8). Adolescents were asked to evaluate a PDF app wireframe consisting of 76 screen shots displaying app features, including log in and home screen, profile setup, settings and info, self-management features, and graphical displays for charting asthma control and medication. Preferences, comments, and suggestions for each set of screen shots were assessed using the audio-recorded interviews. Two coders reached consensus on adolescent evaluations of the following aspects of app features: (1) usability, (2) behavioral intentions to use, (3) confusing aspects, and (4) suggestions for improvement. The app wireframe was generally well received, and several suggestions for improvement were recorded. Suggestions included increased customization of charts and notifications, reminders, and alerts. Participants preferred longitudinal data about asthma control and medication use to be displayed using line graphs. All participants reported that they would find an asthma management app like the one depicted in the wireframe useful for managing their asthma. Early stage usability tests guided by government usability guidelines (usability.gov) revealed areas for improvement for an asthma self-management app for adolescents. Addressing these areas will be critical to developing an engaging and effective asthma self-management app that is capable of improving adolescent asthma outcomes. ©Adam Sage, Courtney Roberts, Lorie Geryk, Betsy Sleath, Deborah Tate, Delesha Carpenter.

Lung function requirements in flying duty the problem of bronchial hyperresponsiveness in military aircrew.

PubMed

Hartmann, C M; Steinhoff-Lankes, D; Maya-Pelzer, P

1999-09-09

Uncompromised lung function is essential for fitness to fly. Under hypobaric conditions there is an increased risk of hypoxemia. G-forces, positive pressure breathing and anti-G maneuvers cause physical stress to the lung tissue and altered pulmonary blood flow. Breathing with pure oxygen, dry cabin air and ozone can cause airway irritation. Chemically and physically by irritating agents may be present. Emergencies such as smoke in the cockpit or inhalation of tear gas can rapidly compromise the pulmonary system in susceptible persons. Sudden incapacitation may occur. Trapped gases may cause overinflation and lung rupture in rapid decompression. Applicants for military duty have to pass basic lung function tests routinely. Preselection of aircrew candidates tends to be even stricter. Asthma and obstructive lung disease are disqualifying. Trained aircrew with late onset of pulmonary problems can be waived under certain restrictions in many cases. Some national regulations exclude even applicants with allergies. Due to aeromedical experience we should always be aware of the latent unspecific bronchial hyperresponsiveness (BHR). BHR is one of the characteristics of asthma bronchiale. If BHR exists there is an increased risk of later development of asthma bronchiale, especially together with perennial allergies such as against house dust mite. Under certain conditions BHR can become symptomatic and aeromedically relevant. In some cases we saw an exacerbation under medication, mostly under beta-receptor-blockers. In one case even under betablocker-containing eye drops. In the Gulf War 1991 a number of allied military personnel had to be withdrawn because of bronchospastic symptoms. This can be explained among others by medication with physostigmine. Physostigmine is a systemically active cholinergic drug which is prophylactically used under threat of chemically warfare agents. In individuals with latent BHR physostigmine will lower the threshold for bronchial reactions considerably and even cause manifest bronchospasm. We recommend an unspecific bronchial challenge test in the selection of personnel for duties where uncompromised lung function under all environmental conditions is essential.

Background: Few studies address concurrent exposures to common household allergens, specific allergen sensitization and childhood asthma morbidity. Objective: To identify levels of allergen exposures that trigger asthma exacerbations in sensitized individuals. Methods: We sampled homes for common indoor allergens (fungi, dust mites (Der p 1, Der f 1), cat (Fel d 1), dog (Can f 1) and cockroach (Bla g 1)) for levels associated with respiratory responses among school-aged children with asthma (N=1233) in a month-long study. Blood samples for allergy testing and samples of airborne fungi and settled dust were collected at enrollment. Symptoms and medication use were recordedmore » on calendars. Combined effects of specific allergen sensitization and level of exposure on wheeze, persistent cough, rescue medication use and a 5-level asthma severity score were examined using ordered logistic regression. Results: Children sensitized and exposed to any Penicillium experienced increased risk of wheeze (odds ratio [OR] 2.12 95% confidence interval [CI] 1.12, 4.04), persistent cough (OR 2.01 95% CI 1.05, 3.85) and higher asthma severity score (OR 1.99 95% CI 1.06, 3.72) compared to those not sensitized or sensitized but unexposed. Children sensitized and exposed to pet allergen were at significantly increased risk of wheeze (by 39% and 53% for Fel d 1>0.12 {mu}g/g and Can f 1>1.2 {mu}g/g, respectively). Increased rescue medication use was significantly associated with sensitization and exposure to Der p 1>0.10 {mu}g/g (by 47%) and Fel d 1>0.12 {mu}g/g (by 32%). Conclusion: Asthmatic children sensitized and exposed to low levels of common household allergens Penicillium, Der p 1, Fel d 1 and Can f 1 are at significant risk for increased morbidity. - Highlights: Black-Right-Pointing-Pointer Few studies address concurrent allergen exposures, sensitization and asthma morbidity.

2011-01-01

Background Purchasers can play an important role in eliminating racial and ethnic disparities in health care. A need exists to develop a compelling "business case" from the employer perspective to put, and keep, the issue of racial/ethnic disparities in health care on the quality improvement agenda for health plans and providers. Methods To illustrate a method for calculating an employer business case for disparity reduction and to compare the business case in two clinical areas, we conducted analyses of the direct (medical care costs paid by employers) and indirect (absenteeism, productivity) effects of eliminating known racial/ethnic disparities in mammography screening and appropriate medication use for patients with asthma. We used Markov simulation models to estimate the consequences, for defined populations of African-American employees or health plan members, of a 10% increase in HEDIS mammography rates or a 10% increase in appropriate medication use among either adults or children/adolescents with asthma. Results The savings per employed African-American woman aged 50-65 associated with a 10% increase in HEDIS mammography rate, from direct medical expenses and indirect costs (absenteeism, productivity) combined, was $50. The findings for asthma were more favorable from an employer point of view at approximately $1,660 per person if raising medication adherence rates in African-American employees or dependents by 10%. Conclusions For the employer business case, both clinical scenarios modeled showed positive results. There is a greater potential financial gain related to eliminating a disparity in asthma medications than there is for eliminating a disparity in mammography rates. PMID:21418594

To describe a mixed-methods approach to develop and test a basic behavioral science-informed intervention to motivate behavior change in 3 high-risk clinical populations. Our theoretically derived intervention comprised a combination of positive affect and self-affirmation (PA/SA), which we applied to 3 clinical chronic disease populations. We employed a sequential mixed methods model (EVOLVE) to design and test the PA/SA intervention in order to increase physical activity in people with coronary artery disease (post-percutaneous coronary intervention [PCI]) or asthma (ASM) and to improve medication adherence in African Americans with hypertension (HTN). In an initial qualitative phase, we explored participant values and beliefs. We next pilot tested and refined the intervention and then conducted 3 randomized controlled trials with parallel study design. Participants were randomized to combined PA/SA versus an informational control and were followed bimonthly for 12 months, assessing for health behaviors and interval medical events. Over 4.5 years, we enrolled 1,056 participants. Changes were sequentially made to the intervention during the qualitative and pilot phases. The 3 randomized controlled trials enrolled 242 participants who had undergone PCI, 258 with ASM, and 256 with HTN (n = 756). Overall, 45.1% of PA/SA participants versus 33.6% of informational control participants achieved successful behavior change (p = .001). In multivariate analysis, PA/SA intervention remained a significant predictor of achieving behavior change (p < .002, odds ratio = 1.66), 95% CI [1.22, 2.27], controlling for baseline negative affect, comorbidity, gender, race/ethnicity, medical events, smoking, and age. The EVOLVE method is a means by which basic behavioral science research can be translated into efficacious interventions for chronic disease populations.

In patients with asthma, smoking has been associated with accelerated decline in pulmonary function, poor disease control and reduced responsiveness to corticosteroids. To assess the influence of current and former smoking on self-reported asthma control and health care use in a large population of asthma patients. The present analysis was conducted following a telephone survey of adult Canadians aged 18 to 54 years who had physician-diagnosed asthma and a smoking history of less than 20 pack-years. Of 893 patients, 268 were former smokers and 108 were current smokers. Daytime and nighttime symptoms, absenteeism from work or school, emergency care use for asthma in the past year, and use of a short-acting bronchodilator without controller medication were reported more frequently by current smokers than nonsmokers and former smokers. Former smokers were not significantly different from nonsmokers with respect to most asthma outcomes. Current smokers with asthma show evidence of poorer asthma control and greater acute care needs than lifelong nonsmokers or former smokers. These observations stress the importance of smoking cessation to help achieve asthma control.

Asthma is a leading cause of emergency department (ED) visits. There has been much debate on the impact of direct to consumer advertising (DTCA) on healthcare. This study seeks to examine the association between DTCA expenditure and asthma-related ED use. In this study, we combined Medicaid administrative data and a national advertising data on asthma medications. The sample size consisted of 180,584 Medicaid-enrolled children between the ages of 5 and 18 years who had an asthma diagnosis. Twenty percent of the Medicaid-enrolled children in the sample had asthma-related ED visits. We found that DTCA expenditure is associated with a decrease in asthma-related ED visits (OR = 0.75; CI: 0.64-0.89). However, at higher levels of DTCA expenditure, the likelihood of asthma-related ED visits increases (OR = 1.25; CI: 1.05-1.49), indicating a decreased relationship between DTCA and asthma-related ED visits. Our findings suggest that DTCA may be associated with improved health outcomes for Medicaid-enrolled children with asthma.

Background Change in the prevalence of asthma-like symptoms in populations of ageing adults is likely to be influenced by smoking, asthma treatment and atopy. Methods The European Community Respiratory Health Survey collected information on prevalent asthma-like symptoms from representative samples of adults aged 20–44 years (29 centres in 13 European countries and Australia) at baseline and 10 and 20 years later (n=7844). Net changes in symptom prevalence were determined using generalised estimating equations (accounting for non-response through inverse probability weighting), followed by meta-analysis of centre level estimates. Findings Over 20 years the prevalence of ‘wheeze’ and ‘wheeze in the absence of a cold’ decreased (−2.4%, 95% CI −3.5 to −1.3%; −1.5%, 95% CI −2.4 to −0.6%, respectively) but the prevalence of asthma attacks, use of asthma medication and hay fever/nasal allergies increased (0.6%, 95% CI 0.1 to 1.11; 3.6%, 95% CI 3.0 to 4.2; 2.7%, 95% CI 1.7 to 3.7). Changes were similar in the first 10 years compared with the second 10 years, except for hay fever/nasal allergies (increase seen in the first 10 years only). Decreases in these wheeze-related symptoms were largely seen in the group who gave up smoking, and were seen in those who reported hay fever/nasal allergies at baseline. Interpretation European adults born between 1946 and 1970 have, over the last 20 years, experienced less wheeze, although they were more likely to report asthma attacks, use of asthma medication and hay fever. Decrease in wheeze is largely attributable to smoking cessation, rather than improved treatment of asthma. It may also be influenced by reductions in atopy with ageing. PMID:28974648

The increased prevalence of transitions between households may have implications for child asthma morbidity. We, therefore, sought to enumerate the prevalence of regularly spending nights sleeping away from home among children admitted to the hospital for asthma and to examine the relationship of nights away to asthma-related readmission. This was a population-based, prospective cohort of 774 children, aged 1–16 years, who were admitted with asthma or bronchodilator-responsive wheezing and enrolled in the Greater Cincinnati Asthma Risks Study. The study took place at Cincinnati Children’s Hospital Medical Center, an urban, academic children’s hospital in the Midwest. The primary exposure was regularly spending nights away from home. Selected covariates included caregiver marital status, shift work, child’s race, income, psychological distress, and running out of/not having medications on hand. The primary outcome was asthma-related readmission within 12 months. A total of 19% were readmitted within 12 months. The 33% of children that spent ≥1 night away from home per week were significantly more likely to be readmitted than those who spent no nights away (25% vs. 16%, p=0.002). Spending nights away from home (adjusted relative risk (aRR) 1.5, 95% confidence interval (CI) 1.2–2.0) and lower income (aRR 2.6, 95% CI 1.1–6.4) were the strongest independent predictors of readmission after adjusting for child age, gender, and race, and caregiver marital status, shift work, risk of psychological distress, and running out of meds. Increased awareness of the multiple settings in which children with asthma live may help shape more comprehensive approaches to asthma care. PMID:24838829

The prevalence of childhood asthma has increased, although the rate of hospitalization for asthma seems to decrease. In Norway, the rate of hospital admission for childhood asthma from 1984 to 2000 increased. The aim of this study was to assess further trends in hospital admissions for childhood asthma up to 2010. A population-based study including children 1-13 yrs of age hospitalized for asthma during six periods from 1984/1985 to 2009/2010 in Rogaland, Norway, was performed. Medical records from 1536 admissions (1050 children) were studied; and gender, age, number of admissions, length of hospital stay, medications and symptoms were recorded. For all age groups, the rate of admissions per 10.000 increased from 20.1 in 1984/85 to 33.7 in 1989/90, but declined to 14.4 in 2009/2010. Rates were highest in boys (OR 1.87; 95% CI: 1.69, 2.09), younger age groups (OR 2.51; 2.38, 2.64) and decreased from 1984 to 2010 (OR 0.92; 0.88, 0.94). The rates of readmissions were higher than for primary admissions (OR 1.33; 1.19, 1.47). From 1984 to 2010, there was an increased use of inhaled corticosteroids prior to admission (6 to 51%) and started at discharge (7 to 37%), and systemic steroids given during admission (19 to 83%). There has been a substantial decline in the rate of hospital admissions for childhood asthma after 1989/1990, with major differences between age groups and genders. The decline could be due to improved care of children with asthma or a real reduction in asthma exacerbations. © 2015 John Wiley & Sons A/S. Published by John Wiley & Sons Ltd.

Background: Studies have linked asthma death to either increased or decreased use of medical services. Methods: A population based case-control study of asthma deaths in 1994–8 was performed in 22 English, six Scottish, and five Welsh health authorities/boards. All 681 subjects who died were under the age of 65 years with asthma in Part I on the death certificates. After exclusions, 532 hospital controls were matched to 532 cases for age, district, and date of asthma admission/death. Data were extracted blind from primary care records. Results: The median age of the subjects who died was 53 years; 60% of cases and 64% of controls were female. There was little difference in outpatient attendance (55% and 55%), hospital admission for asthma (51% and 54%), and median inpatient days (20 days and 15 days) in the previous 5 years. After mutual adjustment and adjustment for sex, using conditional logistic regression, three variables were independently associated with asthma death: fewer general practice contacts (odds ratio 0.82 (95% confidence interval (CI) 0.74 to 0.91) per 5 contacts) in the previous year, more home visits (1.14 (95% CI 1.08 to 1.21) per visit) in the previous year, and fewer peak expiratory flow recordings (0.83 (95% CI 0.74 to 0.92) per occasion) in the previous 3 months. These associations were similar after adjustment for markers of severity, psychosocial factors, systemic steroids, short acting bronchodilators and antibiotics, although the association with peak flow was weakened and just lost significance. Conclusion: Asthma death is associated with less use of primary care services. Both practice and patient factors may be involved and a better understanding of these may offer possibilities for reducing asthma death. PMID:16055628

Caregivers who smoke and have children with asthma are an important group for intervention. Home-based interventions successfully reduce asthma morbidity, yet are costly. This study evaluated the financial return on investment (ROI) of the Parents of Asthmatics Quit Smoking (PAQS) program, a combined asthma education and smoking cessation intervention. Participants included caregivers (n = 224) that smoked, had a child with asthma, and were enrolled in a Medicaid managed care plan. Participants received nurse-delivered asthma education and smoking counseling in three home visits. Program implementation costs were estimated, and healthcare expenses were obtained from insurance claims data 12 months pre- and 12 months post intervention. ROI was calculated for all participants, children <6 years, children 6-18 years, and children with moderate/severe persistent asthma. Total program implementation cost was $34,481. After intervention, there was increased mean annual refills of beta-agonist (0.51 pre, 1.64 post; P < 0.001), and controller medications (0.65 pre, 2.44 post; P < 0.001). Reductions were found in mean annual emergency department visits (0.33 pre, 0.14 post; P < 0.001), hospitalizations (0.23 pre, 0.08 post; P < 0.001), and outpatient visits (2.33 pre, 1.45 post, P < 0.001). The program had negative ROI (-21.8%) for the entire sample. The ROI was positive (+106.9) for children <6 years, negative (-150.3) for children 6-18, and negligible for moderate/severe persistent asthma (+6.9%). PAQS was associated with increased medication use and decreased healthcare utilization. While the overall ROI for PAQS was negative, PAQS had a positive ROI for caregivers of young children with asthma. Copyright © 2012 Wiley Periodicals, Inc.

Although indoor environmental conditions can affect pediatric asthmatic patients, few studies have characterized the effect of building interventions on asthma-related outcomes. Simulation models can evaluate such complex systems but have not been applied in this context. We sought to evaluate the impact of building interventions on indoor environmental quality and pediatric asthma health care use, and to conduct cost comparisons between intervention and health care costs and energy savings. We applied our previously developed discrete event simulation model (DEM) to simulate the effect of environmental factors, medication compliance, seasonality, and medical history on (1) pollutant concentrations indoors and (2) asthma outcomes in low-income multifamily housing. We estimated health care use and costs at baseline and subsequent to interventions, and then compared health care costs with energy savings and intervention costs. Interventions, such as integrated pest management and repairing kitchen exhaust fans, led to 7% to 12% reductions in serious asthma events with 1- to 3-year payback periods. Weatherization efforts targeted solely toward tightening a building envelope led to 20% more serious asthma events, but bundling with repairing kitchen exhaust fans and eliminating indoor sources (eg, gas stoves or smokers) mitigated this effect. Our pediatric asthma model provides a tool to prioritize individual and bundled building interventions based on their effects on health and costs, highlighting the tradeoffs between weatherization, indoor air quality, and health. Our work bridges the gap between clinical and environmental health sciences by increasing physicians' understanding of the effect that home environmental changes can have on their patients' asthma.

Rosenman, K D; Beckett, W S

2015-05-01

Work-related asthma is common and yet remains a challenge to diagnose. Access to a listing of agents associated with work-related asthma has been suggested as useful in assisting in the diagnosis. The Association of Occupational and Environmental Clinics (AOEC) developed criteria that were used to review the peer-reviewed medical literature published in English. Based on this review, substances were designated either as a sensitizing agent or an irritant. The reviews were conducted by a board certified internist/pulmonologist/occupational medicine specialist from 2002 to 2007 and a board certified internist/occupational medicine physician from 2008- date. All reviews were then reviewed by the nine member AOEC board of directors. The original list of agents associated with new onset work-related asthma was derived from the tables of a text book on work-related asthma. After 13 years of review, there are 327 substances designated as asthma agents on the AOEC list; 173 (52.9%) coded as sensitizers, 35 (10.7%) as generally recognized as an asthma causing agent, four (1.2%) as irritants, two (0.6%) as both a sensitizer and an irritant and 113(34.6%) agents that still need to be reviewed. The AOEC has developed a readily available web based listing of agents associated with new onset work-related asthma in adults. The listing is based on peer-reviewed criteria. The listing is updated twice a year. Regular review of the peer-reviewed medical literature is conducted to determine whether new substances should be added to the list. Clinicians should find the list useful when considering the diagnosis of work-related asthma. Copyright © 2015 Elsevier Ltd. All rights reserved.

Data on the association between atopic diseases and attention-deficit/hyperactivity disorder (ADHD) have been inconclusive. To assess whether children with drug-treated ADHD are more likely to receive treatment for asthma, allergic rhinitis, or eczema before the start of ADHD medication use compared with controls and to examine the effect of parents receiving medication for ADHD and atopic diseases on ADHD medication use in their offspring. We conducted a retrospective nested case-control study among children (6-12 years of age) using the Groningen University prescription database. Cases were defined as children with at least 2 prescriptions of methylphenidate within 12 months. For each case, 4 controls were matched on age, sex, and regional area code. Parental prescription data were linked to cases and controls to assess the influence of parents receiving medication for ADHD and atopic diseases on ADHD medication use in their offspring. We identified 4257 cases and 17,028 matched controls. Drug treatment for asthma, allergic rhinitis, and eczema was more common in cases than controls (adjusted odds ratios [aORs], 1.4 [95% confidence interval (CI), 1.3-1.6], 1.4 [95% CI, 1.1-1.8], and 1.3 [95% CI, 1.1-1.5], respectively). Medication for allergic rhinitis and asthma among parents was associated with ADHD treatment in their children (aORs, 1.3 [95% CI, 1.1-1.5] and 1.2 [95% CI, 1.1-1.3], respectively). This study provides further evidence to support the hypothesis that atopic diseases are associated with ADHD. The parental-offspring association suggests a possible genetic and/or environmental component. Copyright © 2016 American College of Allergy, Asthma & Immunology. Published by Elsevier Inc.

In 2011 the Latin America Asthma Insight and Management (LA AIM) survey explored the realities of living with asthma. We investigated perception, knowledge, and attitudes related to asthma among Latin American asthma patients. Asthma patients aged ≥12 years from four Latin American countries (Argentina, Brazil, Mexico, Venezuela) and the Commonwealth of Puerto Rico responded to questions during face-to-face interviews. A sample size of 2,169 patients (approximately 400 patients/location) provided an accurate representation of asthma patients' opinions. Questions probed respondents' views on topics such as levels of asthma control, frequency and duration of exacerbations, and current and recent use of asthma medications. A total of 2,169 adults or parents of children with asthma participated in the LA AIM survey. At least 20% of respondents experienced symptoms every day or night or most days or nights. Although 60% reported their disease as well or completely controlled, only 8% met guideline criteria for well-controlled asthma. 47% of respondents reported episodes when their asthma symptoms were more frequent or severe than normal, and 44% reported seeking acute care for asthma in the past year. Asthma patients in Latin America overestimated their degree of asthma control. The LA AIM survey demonstrated the discrepancy between patient perception of asthma control and guideline-mandated criteria. Additional education is required to teach patients that, by more closely following asthma management strategies outlined by current guidelines more patients can achieve adequate asthma control.

Novel therapies need to be evaluated in normal clinical practice to allow a true representation of the treatment effectiveness in real-world settings. The Salford Lung Study is a pragmatic randomised controlled trial in adult asthma, evaluating the clinical effectiveness and safety of once-daily fluticasone furoate (100 μg or 200 μg)/vilanterol 25 μg in a novel dry-powder inhaler, versus existing asthma maintenance therapy. The study was initiated before this investigational treatment was licensed and conducted in real-world clinical practice to consider adherence, co-morbidities, polypharmacy, and real-world factors. Asthma Control Test at week 24; safety endpoints include the incidence of serious pneumonias. The study utilises the Salford electronic medical record, which allows near to real-time collection and monitoring of safety data. The Salford Lung Study is the world's first pragmatic randomised controlled trial of a pre-licensed medication in asthma. Use of patients' linked electronic health records to collect clinical endpoints offers minimal disruption to patients and investigators, and also ensures patient safety. This highly innovative study will complement standard double-blind randomised controlled trials in order to improve our understanding of the risk/benefit profile of fluticasone furoate/vilanterol in patients with asthma in real-world settings.

Airway smooth muscle (ASM) plays a key role in bronchomotor tone, as well as in structural remodeling of the bronchial wall. Therefore, ASM contraction and proliferation significantly participate in the development and progression of asthma. Many contractile agonists also behave as mitogenic stimuli, thus contributing to frame a hyperresponsive and hyperplastic ASM phenotype. In this review, the molecular mechanisms and signaling pathways involved in excitation-contraction coupling and ASM cell growth will be outlined. Indeed, the recent advances in understanding the basic aspects of ASM biology are disclosing important cellular targets, currently explored for the implementation of new, more effective anti-asthma therapies.

Proper asthma management and control depend on patients having affordable access to healthcare yet financial barriers to asthma care are common. To examine associations of work-related asthma (WRA) with financial barriers to asthma care and adverse asthma outcomes. Cross-sectional, random-digit-dial survey conducted in 37 states and District of Columbia. A total of 27,927 ever-employed adults aged ≥18 years with current asthma. Prevalence ratios (PR) for the associations of WRA with financial barriers to asthma care and of WRA with adverse asthma outcomes stratified by financial barriers. Persons with WRA were significantly more likely than those with non-WRA to have at least 1 financial barrier to asthma care [PR, 1.66; 95% confidence interval (CI), 1.43-1.92]. Individuals with WRA were more likely to experience adverse asthma outcomes such as asthma attack (PR, 1.31; 95% CI, 1.22-1.40), urgent treatment for worsening asthma (PR, 1.57; 95% CI, 1.39-1.78), asthma-related emergency room visit (PR, 1.69; 95% CI, 1.41-2.03), and very poorly controlled asthma (PR, 1.54; 95% CI: 1.36-1.75). After stratifying for financial barriers to asthma care, the associations did not change. Financial barriers to asthma care should be considered in asthma management, and individuals with WRA are more likely to experience financial barriers. However, individuals with WRA are more likely to experience adverse asthma outcomes than individuals with non-WRA, regardless of financial barriers. Additional studies are needed to identify medical, behavioral, occupational, or environmental factors associated with adverse asthma outcomes among individuals with WRA.

Retrospective chart review, single group, preintervention and postintervention. Pharmacist-managed asthma clinic at an Indian Health Service ambulatory care clinic. Sixty-one AI/AN patients who were seen at least once in the asthma clinic from 2010 to 2014. Pharmacist-provided asthma education and medication management. Asthma-related hospitalizations and emergency department or urgent care (ED) visits. The total number of asthma-related hospitalizations and ED visits between the 12-month periods preceding and following the initial asthma clinic visit were 11 versus 2 hospitalizations (P = 0.02) and 43 versus 25 ED visits (P = 0.02), respectively. Over the same period, asthma-related oral corticosteroid use showed a nonsignificant decrease in the number of prescriptions filled (n = 59, P = 0.08). In contrast, inhaled corticosteroid prescription fills significantly increased (n = 42, P = 0.01). A reduction of asthma-related hospitalizations and ED visits were observed during the course of the intervention. Increased access to formal asthma education and appropriate asthma care benefit the Yakama AI/AN people. A controlled trial is needed to confirm that the intervention causes the intended effect.

Proper asthma management in schools is important in achieving optimum asthma control in children with asthma. The National Heart, Lung, and Blood Institute (NHLBI) has developed guidelines on classroom asthma management. We conducted a systematic review to examine teacher knowledge of the NHLBI guidelines on asthma management in the classroom. We searched PubMed and EMBASE using search terms "asthma management," "teacher(s)," "school teacher," and "public school." The inclusion criteria were articles published in English from 1994 to May 2014 that focus on schools in the United States (US). From 535 titles and abstracts, 9 studies met inclusion criteria. All studies reported that school teachers did not know the policies and procedures of asthma management. Teachers relied on school nurses to handle medical emergencies. Some studies identified that lack of full-time school nurses was a barrier to asthma management. Only one study showed directly that classroom teachers were not following the NHLBI guidelines on asthma management. Our literature review revealed that US teachers do not know the NHLBI guidelines on asthma management in the classroom. Future research should focus on interventions targeted toward training classroom teachers on asthma management as per NHLBI guidelines to ultimately improve asthma management in schools.

Some human and animal studies have recently shown that maternal grandmother's smoking during pregnancy increases the risk of asthma in the grandchildren. We have investigated whether sex of the exposed parent and/or grandchild modifies the association between grandmaternal smoking and grandchild asthma. We formed a cohort study based on linkage of national registries with prospectively collected data over three generations. Smoking habits in early pregnancy were registered since 1982 and purchases of prescribed medication since 2005. In all, 10 329 children born since 2005 had information on maternal and grandmaternal smoking on both sides and were followed from birth up to 6 years of age. Ages when medication was purchased were used to classify the cohort into never, early transient (0-3 years), early persistent (0-3 and 4-6 years), and late-onset (4-6 years) phenotypes of childhood asthma. Maternal grandmother's smoking was associated with an increased odds of early persistent asthma after adjustment for maternal smoking and other confounders (odds ratio 1.29, 95% confidence interval 1.10-1.51). Grandchild sex did not modify the association. Paternal grandmother's smoking was not associated with any of the asthma phenotypes. Maternal but not paternal exposure to nicotine before conception was related to an increased risk of early persistent childhood asthma, but not other asthma phenotypes. Our findings are possibly consistent with a sex-specific mode of epigenetic transfer. © 2018 EAACI and John Wiley and Sons A/S. Published by John Wiley and Sons Ltd.

New York City residents were exposed to a variety of inhaled substances after the collapse of the World Trade Center. Exposure to these substances might lead to an increase in asthma severity, with residential distance from Ground Zero predictive of the degree of change. We sought to assess the effect of the World Trade Center collapse on local pediatric asthmatic patients. We retrospectively reviewed the charts of 205 pediatric patients with established asthma from a clinic in lower Manhattan's Chinatown. Clinical data were obtained for the year before and the year after September 11, 2001. Measurements included numbers of visits, asthma medication prescriptions, oral corticosteroid prescriptions, weekly doses of rescue inhaler, and peak expiratory flow rates. Residential zip codes were used to compare the asthma severity of patients living within and beyond a 5-mile radius of Ground Zero. After September 11, 2001, these children had more asthma-related clinic visits (P = .002) and received more prescriptions for asthma medications (P = .018). No significant differences in oral steroid or rescue inhaler use were noted. Those living within 5 miles had more clinic visits after September 11, 2001 (P = .013); the increase in clinic visits for patients living more than 5 miles from Ground Zero was not significant. Mean percent predicted peak expiratory flow rates decreased solely for those patients living within 5 miles of Ground Zero during the 3 months after September 11, 2001. Asthma severity worsened after September 11, 2001, in pediatric asthmatic patients living near Ground Zero. Residential proximity to Ground Zero was predictive of the degree of decrease in asthma health.

Origin of anorectal malformations (ARM) are considered multifactorial. Several genetic and non-genetic risk factors are discussed in literature. Maternal periconceptional medical drug use as possible risk factor, however, has not been reviewed systematically. Studies published between 1977 and April 2017 were reviewed through systematic search in PubMed, ISI Web of Knowledge and Scopus databases. Furthermore, related and cross-referencing publications were reviewed. Pooled odds ratios (95% confidence intervals) were determined to quantify associations of maternal periconceptional use of folic acid, multivitamins, anti-asthma medication (separated in any anti-asthma medication, inhaled corticosteroids and salbutamol), thyroid hormone supplements, psychiatric drugs (separated in antidepressants, any selective serotonin reuptake inhibitors [SSRI], sertraline, citalopram, fluoxetine, paroxetine, hypnotics and benzodiazepine) and aspirin with ARM using meta-analyses. Thirty-seven studies that reported on the association between maternal periconceptional drug intake and infants born with ARM were included in this review. These were conducted in the United States of America (n = 14), Sweden (n = 6), Hungary (n = 5), Germany (n = 3), the Netherlands (n = 3), Denmark (n = 2), France (n = 2), Norway (n = 1) and the UK (n = 1). However, only few of these studies reported on the same risk factors. Studies were heterogeneous with respect to case numbers, period ingestion of medical drug use, control selection and adjustment for covariates. Consistently increased risks were observed for any anti-asthma medication, and hypnotics and benzodiazepine, but not for folic acid, multivitamins, inhaled corticosteroids, salbutamol, thyroid hormone supplements, antidepressants, any SSRI, sertraline, citalopram, fluoxetine, paroxetine and aspirin. In meta-analyses, pooled odds ratios (95% confidence intervals) for any anti-asthma medication, and hypnotics and benzodiazepine were 1.64 (1.22-2.21), and 2.43 (1.03-5.73), respectively. Evidence on maternal drug use before conception and during pregnancy as risk factor for ARM from epidemiological studies is still very limited. Nevertheless, the few available studies indicate any anti-asthma medication, and hypnotics and benzodiazepine to be associated with increased risks. Further, ideally large-scale multicenter and register-based studies are needed to clarify the role of maternal drug intake for the development of ARM.

Inhaled short-acting beta-agonist (SABA) medication is commonly used in asthma patients to rapidly reverse airway obstruction and improve acute symptoms. We performed a genome-wide association study of SABA medication response using gene-based association tests. A linear mixed model approach was first used for single-nucleotide polymorphism associations, and the results were later combined using GATES to generate gene-based associations. Our results identified SPATA13-AS1 as being significantly associated with SABA bronchodilator response in 328 healthy African Americans. In replication, this gene was associated with SABA response among the two separate groups of African Americans with asthma (n=1073, P=0.011 and n=1968, P=0.014), 149 healthy African Americans (P=0.003) and 556 European Americans with asthma (P=0.041). SPATA13-AS1 was also associated with longitudinal SABA medication usage in the two separate groups of African Americans with asthma (n=658, P=0.047 and n=1968, P=0.025). Future studies are needed to delineate the precise mechanism by which SPATA13-AS1 may influence SABA response.

Childhood asthma: considerations for primary care practice and chronic disease management in the village of care.

Rosenthal, Michael P

2012-06-01

Childhood asthma is at historically high levels, with significant morbidity and mortality. Despite more than two decades of improved understanding of childhood asthma care and the evolution of beneficial medications, widespread control remains poor, leading to suboptimal patient outcomes and quality of life. This lack of control results in excessive emergency department use, hospitalizations, and inappropriate and/or unnecessary costs to the health care system. Advanced practice models that incorporate community-based approaches and services for childhood asthma are needed. Innovative, community-included methods of care to address the burden of childhood asthma may provide examples for care of other chronic diseases. Copyright © 2012 Elsevier Inc. All rights reserved.

Pediatric asthma is often undiagnosed, and therefore untreated. It negatively impacts children's functioning, including school attendance and performance, as well as quality of life. Schoolwide screening for asthma is becoming increasingly common, making identification of possible asthma particularly relevant for school nurses. Nurses may need to help parents cope with the new diagnosis, and teach them skills to manage the illness. The aim of this article is to present a three-phase model of how parents cope with a newly diagnosed pediatric chronic illness. Using asthma as an example, we describe these phases (Emotional Crisis, Facing Reality, and Reclaiming Life), illustrate how parents progress through the phases, and discuss situations associated with possible regression. Next, we offer strategies framed around a theory of asthma self-management to assist school nurses and other medical providers to motivate parents to develop successful disease management skills.

Occupational asthma in a national disability survey

The contribution of workplace exposures to the prevalence of asthma in adults has been minimized in the epidemiology of this illness. Analysis of the 1978 Social Security Disability Survey provides a population-based assessment as a novel approach utilizing self-attributed, occupationally related asthma as a measure of disease. Of 6063 respondents, 468 (7.7 percent) identified asthma as a personal medical condition; 72 (1.2 percent (15.4 percent of all those with asthma)) attributed it to workplace exposures. These subjects were older and included more men and cigarette smokers than groups of both asthmatic and nonasthmatic subjects. The relative risk for occupationally attributedmore » asthma was elevated among industrial and agricultural workers as compared with white collar and service occupations. Analysis of disability benefit status did not indicate that this introduced major reporting bias in this survey. This study suggests that occupational factors may have a greater role in adult asthma than previously thought.« less

A multicomponent model has been developed to explain patients' unmet expectations of medical care. The model proposes that expectations are related to patients' personal experiences with illness, perceived vulnerability to disease, transmitted knowledge, and perceived severity of disease. The objective of this cross-sectional study was to determine whether this model can be applied to patients' unrealistic expectations of treatment outcomes, specifically expecting to be cured of asthma. In total, 230 patients observed in a primary care practice in New York City were interviewed in person with open-ended questions about their expectations of asthma treatment. Responses were analyzed with qualitative techniques to generate categories of expectations. Patients had a mean age of 41 +/- 11 years, 21% were white, 30% African American, 42% Latino, and 7% other groups. Major categories of expectations were generated from patients' responses and included symptom relief (expected by 52%), cure (36%), improved physical function (21%), and improved psychological well-being (15%). The category of expecting a cure was assessed with patients' responses to the following items representing components of the model: 1) resource utilization and medication requirements for asthma (representing severity of disease); 2) perceived quality of asthma care and satisfaction with care (representing past asthma experiences); 3) the Asthma Self-Efficacy Scale (representing perceived vulnerability to exacerbations); and 4) experiences of social network contacts with asthma and the Check Your Asthma IQ survey (representing transmitted knowledge). In bivariate analysis, patients who expected a cure were more likely to be Latino or Native American or Asian (p = 0.02), to have never required oral corticosteroids (p = 0.004), to be dissatisfied with the status of their asthma (p = 0.008), to know others who were limited by asthma (p = 0.03), to have worse Asthma Self-Efficacy Scale scores (p = 0.002), to have worse Check Your Asthma IQ scores (p = 0.04), and to currently be taking inhaled corticosteroids (p = 0.03). In multivariate analysis, worse asthma self-efficacy (p = 0.008), never having required oral corticosteroids (p = 0.005), and currently taking inhaled corticosteroids (p = 0.05) remained associated with expecting a cure. As a result of this study, we found that patients have multiple expectations of asthma treatment, including realistic expectations such as symptom relief and improved function, as well as unrealistic expectations, specifically to be cured of asthma. A multicomponent model of patient and disease characteristics was associated with this unrealistic expectation. These findings indicate that clinicians can intervene in diverse areas to foster realistic expectations of treatment outcomes among asthma patients.

Objective To compare asthma care roles of maternal and paternal caregivers, and examine associations between caregiver involvement and the outcomes of adherence, morbidity, and parental quality of life (QoL). Methods Mothers and fathers in 63 families of children, ages 5–9 years, with persistent asthma completed semistructured interviews and questionnaires. Adherence was measured via electronic monitoring. Paired t tests compared parental asthma care roles, and analysis of covariance, controlling for socioeconomic status, evaluated associations of asthma outcomes with caregiver involvement scores. Results Mothers had higher scores on measures of involvement, beliefs in medication necessity, and on four subscales of the Family Asthma Management System Scale interview (Asthma Knowledge, Relationship with Provider, Symptom Assessment, and Response to Symptoms). Maternal QoL was lowest when both maternal and paternal involvement was high. Paternal involvement was associated with increased morbidity. Conclusions There is room for enhancement of fathers’ asthma care roles. Higher levels of paternal involvement may be driven by family need. PMID:25922295

Little is known about doctors' treatment preferences for childhood asthma. The aim of this study was to investigate adherence to management guidelines for childhood asthma. One thousand general practitioners (GPs) and paediatric specialists in Australia were invited to take part in a survey, which collected demographic details and explored their familiarity with and adherence to childhood asthma management guidelines. Two hundred doctors (20% response rate) responded and were eligible for inclusion in the survey. Approximately half (54.5%) of the respondents were very familiar with at least one of the childhood asthma management guidelines. The majority of respondents (86.8%) followed guideline recommendations when prescribing initial maintenance therapy for childhood asthma, while 89.2% and 68.0% followed guideline recommendations regarding step-up and step-down therapy respectively. Overall familiarity with childhood asthma management guidelines could be improved. There is scope for improvement in the adherence to these guidelines when prescribing medication in childhood asthma, particularly for step-down therapy.

The "zero death from asthma strategy" in the medical treatment for bronchial asthma has been promoted by the Ministry of Health, Labour, and Welfare from 2006, and it indicates that medical and non-medical specialists, as well as pharmacists, should cooperate, and strives to build cooperation which is suited the actual conditions of an area. It is also important for COPD. Although hospitals in some areas cooperate with clinics and pharmacies, the overall concept of cooperation appears to be absent in most Japanese hospitals. A questionnaire was administered in early March, 2012 to 477 allergology institutions, and was authorized by an educational establishment. Among 246 replies from the institutions, cooperation between hospitals and clinics was carried out by 98 institutions (39.8%) specializing in bronchial asthma, and in 64 institutions (37.2%) specializing in COPD. However, cooperation tools were used in only 37 of these institutions (15.0%). The ability to fill prescriptions outside the hospital was available in 209 institutions (85.0%). One-hundred and seventeen institutions (47.6%) replied that they have no tools for hospital-pharmacy cooperation. Direct indications were written in prescriptions by 82 institutions (33.3). In order to build inter-regional association and to equalize medical treatment, we suggest that developing tools and organization for cooperation between health professionals who treat patients with bronchial asthma and COPD is necessary.

The purpose of this study was to evaluate the association between asthma status and the occurrence and length of work absences among the US working adults. A cross-sectional study was conducted using the 2008 Medical Expenditure Panel Survey (MEPS). Employed respondents between ages 18 and 55 years were included. The association between asthma status (whether respondents have asthma or not) and occurrence of absences and the length of time per absence was evaluated using a two-part model. A multivariate logistic regression as the first part of the model was to estimate the probability of being absent from work at least once during the observation period as a function of asthma status. A multivariate negative binomial regression as the second part of the model was used to assess whether the length of each absence from work was associated with asthma status among respondents who reported at least one absence from work. Sociodemographic, socioeconomic, employment-related, health status, and comorbidity variables were included in each model as covariates. Of 12,161 respondents, 8.2% reported having asthma, which accounted for 10.4 million working adults in the United States in 2008. Employed adults with asthma were more likely to report having at least one absence from work compared to those without asthma in bivariate analyses (26.2% vs. 16.2%, p < .01). After adjusting for the number of comorbid chronic conditions and other covariates, there was no significant difference between having asthma and absenteeism among respondents (odds ratio (OR) = 1.31, 95% confidence interval (CI) = 0.99-1.72, rate ratio (RR) = 1.25, 95% CI = 0.91-1.72). Overall burden of illness as measured by comorbidity indices and perceived health status, but not asthma alone, contributes to absenteeism as well as the number of days off during each occurrence among employed people. It is important for health services researchers to consider overall burden of illness when examining the association between a general outcome such as absence from work and specific conditions such as asthma.

There is controversy as to whether low levels of air pollution affect the symptoms and lung function in asthma. We addressed this by examining the short-term effects of winter air pollution on childhood asthma in Paris. We performed a 6 month follow-up of 84 medically diagnosed asthmatic children classified into two groups of severity. The outcomes included incidence and prevalence of asthma attacks, symptoms and use of supplementary beta2-agonists, peak expiratory flow (PEF) value and its variability. The statistical analysis controlled the lack of independence between daily health outcomes, trends and meteorology. Air pollution was associated with an increase in reports and duration of asthma attacks and asthma-like symptoms in mild asthmatic children. The strongest association was the risk of asthma attack for an increase of 50 microg x m(-3) of sulphur dioxide (SO2) on the same day (odds ratio (OR)=2.86). Maximum reduction in morning peak expiratory flow (PEF) (5%) and maximum increase in PEF variability (2%) were observed at a lag of 3 days for an increase of 50 microg x m(-3) of SO2 in the subgroup of mild asthmatics receiving no regular inhaled medication. In moderate asthmatic children, the duration of supplementary beta2-agonist use was strongly associated with air pollution. The general pattern of our results provides evidence of the effect of the low levels of air pollution encountered in Western Europe on symptoms and lung function in childhood asthma.

An accurate estimation of the prevalence of paediatric asthma in Alberta and elsewhere is hampered by uncertainty regarding disease definition and diagnosis. Electronic medical records (EMRs) provide a rich source of clinical data from primary-care practices that can be used in better understanding the occurrence of the disease. The Canadian Primary Care Sentinel Surveillance Network (CPCSSN) database includes cleaned data extracted from the EMRs of primary-care practitioners. The purpose of the study was to develop and validate a case definition of asthma in children 1–17 who consult family physicians, in order to provide primary-care estimates of childhood asthma in Alberta as accurately as possible. The validation involved the comparison of the application of a theoretical algorithm (to identify patients with asthma) to a physician review of records included in the CPCSSN database (to confirm an accurate diagnosis). The comparison yielded 87.4% sensitivity, 98.6% specificity and a positive and negative predictive value of 91.2% and 97.9%, respectively, in the age group 1–17 years. The algorithm was also run for ages 3–17 and 6–17 years, and was found to have comparable statistical values. Overall, the case definition and algorithm yielded strong sensitivity and specificity metrics and was found valid for use in research in CPCSSN primary-care practices. The use of the validated asthma algorithm may improve insight into the prevalence, diagnosis, and management of paediatric asthma in Alberta and Canada. PMID:27882997

To describe the clinical characteristics of pediatric asthmonia, a syndrome in which children have both an acute asthma exacerbation and a concomitant diagnosis of community acquired pneumonia. A retrospective chart review was conducted on children admitted to Connecticut Children's Medical Center in the pediatric emergency department from January 1, 2012 to December 31, 2012. Children with asthma and pneumonia were identified using ICD-9 codes 493 (asthma) or 482 (pneumonia). In this study, we defined asthmonia, a third group, based on the following criteria: (1) history of asthma based on documentation in the past medical history section of the chart, (2) documented wheezing on presentation, (3) administration of bronchodilator(s), and (4) new focal infiltrate on chest radiograph during ED visit. The three nonoverlapping groups (asthma, pneumonia, and asthmonia) were described. Three hundred and sixty-eight children were identified for our study population. In the study population, 66.0% (N = 243) had asthma, 20.4% (N = 75) pneumonia, and 13.6% (N = 50) met our definition of asthmonia. We found that 84.0% (N = 42) of children who met asthmonia criteria in our study were treated with antibiotic therapies. Also, 28.0% (N = 14) of children who met asthmonia criteria had documented fever during admission or by parent report. This study defined clinical features of the coexistence of pneumonia in children with asthma. Overall, these children frequently presented with fever and were treated with antibiotics. More studies are needed to better elucidate this clinical entity and its ramifications.

Asthma education: different viewpoints elicited by qualitative and quantitative methods.

This project began as a qualitative examination of how asthma education provided by health professionals could be improved. Unexpected qualitative findings regarding the use of Asthma Action Plans and the importance of insurance reimbursement for asthma education prompted further quantitative examination. Qualitative individual interviews were conducted with primary care physicians in private practice who routinely provide initial diagnoses of asthma and focus groups were conducted with other clinicians in private primary care practices who routinely provide asthma education. Using the DocStyles quantitative tool two questions regarding Asthma Action Plans and insurance reimbursement were asked of a representative sample of physicians and other clinicians. The utility of Asthma Action Plans was questioned in the 2012 qualitative study. Qualitative findings also raised questions regarding whether reimbursement is the barrier to asthma education for patients performed by medical professionals it is thought to be. 2013 quantitative findings show that the majority of clinicians see Asthma Action Plans as useful. The question of whether reimbursement is a barrier to providing asthma education to patients was not resolved by the quantitative data. The majority of clinicians see Asthma Action Plans as a useful tool for patient education. Clinicians had less clear opinions on whether the lack of defined reimbursement codes acted as a barrier to asthma education. The study also provided useful audience data for design of new asthma educational tools developed by CDC.

Variable expression is one aspect of the heterogeneity of asthma. We aimed to define a variable pattern, which is relevant in general health epidemiological cohorts. Our objectives were to assess whether: 1) asthma patterns defined using simple asthma questions through repeated measurements could reflect disease variability 2) these patterns may further be classified according to asthma severity/control. Among 70,428 French women, we used seven questionnaires (1992–2005) and a comprehensive reimbursement database (2004–2009) to define three reliable asthma patterns based on repeated positive answers to the ever asthma attack question: “never asthma” (n = 64,061); “inconsistent” (“yes” followed by “no”, n = 3,514); “consistent” (fully consistent positive answers, n = 2,853). The “Inconsistent” pattern was related to both long-term (childhood-onset asthma with remission in adulthood) and short-term (reported asthma attack in the last 12 months, associated with asthma medication) asthma variability, showing that repeated questions are relevant markers of the variable expression of asthma. Furthermore, in this pattern, the number of positive responses (1992–2005) predicted asthma drug consumption in subsequent years, a marker of disease severity. The “Inconsistent” pattern is a phenotype that may capture the variable expression of asthma. Repeated answers, even to a simple question, are too often neglected. PMID:23741466

Knowledge transfer from theory to practice in healthcare systems poses a challenge worldwide. Typical examples include national disease management guidelines. The present study contributes towards improving implementation strategies for an asthma guideline. A guideline implementation strategy was examined in a four-armed, non-randomised, controlled intervention study with an additional control group. The study participants were general practitioners and paediatricians recruited from primary care quality circles. All study participants attended an interactive seminar on the evidence-based recommendations for patients with asthma. In addition, the participants were asked to choose among the following options: no further intervention, additional e-learning, training of their practice nurses, or e-learning and training of their practice nurses. The success of the intervention was measured by questionnaire (and the success rate expressed as a percentage). About one third of all participants (n=313) opted for the combination of an interactive seminar and a training of practice nurses; two third preferred the classic way of continuing medical education with an interactive seminar without a further intervention. Just 10 % of the physicians participated in e-learning. Independently of their choice for continuing medical education, all participants demonstrated an increase in knowledge about asthma and an improvement in the management of asthma. The physicians exhibited an average increase in both categories of about 10 % of the percentage values, compared to an increase of about 28 % among the practice nurses without continuing medical education. The physicians' free choice of the educative modules might be an integral part of successful implementation strategies. However, this will require a change of focus from general continuing medical education packages to a more individualised culture of continuing professional development in Germany. Copyright © 2015.

To audit the quality of acute asthma care in two tertiary hospitals in a state in the southwestern region of Nigeria and to compare the clinical practice against the recommendations of the Global Initiative for Asthma (GINA) guideline. We carried out a retrospective analysis of 101 patients who presented with acute exacerbation of asthma to the hospital between November 2010 and October 2015. Majority of the cases were females (66.3%), <45 years of age (60.4%), and admitted in the wet season (64.4%). The median duration of hospital stay was 2 days (interquartile range; 1-3 days) and the mortality was 1.0%. At admission, 73 (72.3%) patients had their triggering factors documented and 33 (32.7%) had their severity assessed. Smoking status, medication adherence, serial oxygen saturation, and peak expiratory flow rate measurement were documented in less than half of the cases, respectively. Seventy-six (75.2%) patients had nebulized salbutamol, 89 (88.1%) had systemic corticosteroid, and 78 (77.2%) had within 1 h. On discharge, 68 (67.3%) patients were given follow-up appointment and 32 (31.7%) were reviewed within 30 days after discharge. Less than half were prescribed an inhaled corticosteroid (ICS), a self-management plan, or had their inhaler technique reviewed or controller medications adjusted. Overall, adherence to the GINA guideline was not satisfactory and was very poor among the medical officers. The quality of acute asthma care in our setting is not satisfactory, and there is a low level of compliance with most recommendations of asthma guidelines. This audit has implicated the need to address the non-performing areas and organizational issues to improve the quality of care.

Self-management of moderate-to-severe asthma depends on the patient's ability to (1) navigate (access health care to obtain diagnoses and treatment), (2) use inhaled corticosteroids (ICSs) properly, and (3) understand ICS function. We sought to test whether navigation skills (medication recall, knowledge of copay requirements, and ability to provide information needed for a medical visit about a persistent cough unresponsive to medication) are related to other self-management skills and health literacy. A 21-item Navigating Ability (NAV2) questionnaire was developed, validated, and then read to adults with moderate-to-severe asthma. ICS technique was evaluated by using scales derived from instructions in national guidelines; knowledge of ICS function was evaluated by using a validated 10-item questionnaire. Spearman correlation was computed between NAV2 score and these questionnaires and with numeracy (Asthma Numeracy Questionnaire) and print literacy (Short Test of Functional Health Literacy in Adults). Two hundred fifty adults participated: age, 51 ± 13 years; 72% female; 65% African American; 10% Latino; 50% with household income of less than $30,000/y; 47% with no more than a 12th-grade education; and 29% experienced hospitalizations for asthma in the prior year. A higher NAV2 score was associated with correct ICS technique (ρ = 0.24, P = .0002), knowledge of ICSs (ρ = 0.35, P < .001), better print literacy (ρ = 0.44, P < .001), and numeracy (ρ = 0.41, P < .001). Patients with poor navigational ability are likely to have poor inhaler technique and limited understanding of ICS function, as well as limited numeracy and print literacy. Clinicians should consider these elements of self-management for their effect on asthma care and as a marker of more general health literacy deficits.

Asthma is a major cause of morbidity and mortality and is associated with significant economic burden worldwide. The objectives of this study were to map current resource use associated with the disease management and to estimate the annual direct and indirect costs per adult patient with asthma. A Delphi panel with seven leading pulmonologists was conducted. A semistructured questionnaire was developed to elicit data on resource use and treatment patterns. Unit costs from official, published sources were subsequently assigned to resource use to estimate direct medical costs. Indirect costs were estimated as number of work loss days. Cost base year was 2015, and the perspective adopted was that of the National Organization of Health Care Services Provision, as well as the societal. Patients with asthma are mainly managed by pulmonologists (71.4%) and secondarily by general practitioners and internists (28.6%). The annual cost of managing exacerbations was estimated at €273.1, while maintenance costs were estimated at €1,100.2 per year. Total costs of managing asthma per patient per year were estimated at €2,281.8, 64.4% of which represented direct medical costs. Of the direct costs, pharmaceutical treatment was the key driver, accounting for 63.9 and 41.2% of direct and total costs, respectively. Direct non-medical costs (patient travel and waiting time) were estimated at €152.3. Indirect costs accounted for 28.9% of total costs. Asthma is a chronic condition, the management of which constrains the already limited Greek health care resources. The increasing prevalence of the disease raises concerns as it could translate per patient costs into a significant burden for the Greek health care system. Thus, the prevention, self-management, and improved quality of care for asthma should find a place in the health policy agenda in Greece.

Upper airway obstruction is commonly misdiagnosed as asthma. We report on four children with recurrent respiratory symptoms who had been erroneously diagnosed as having asthma and who received anti-asthma medication for several years. The evaluation of spirometry tracing was neglected in all cases. Subglottic stenosis, tracheomalacia secondary to tracheo-esophageal fistula, double aortic arch, and vocal cord dysfunction were suspected by direct inspection of the flow-volume curves and eventually diagnosed. The value of clinical history and careful evaluation of spirometry tracing in children with persistent respiratory symptoms is critically discussed. © 2015 John Wiley & Sons A/S.

Among the Hispanic community, Puerto Ricans have the highest prevalence of asthma and manifest the worst outcomes. The expected growth of the Hispanic population in the USA in the next several decades make elimination of disparate care in Puerto Rican asthmatics a matter of national importance. The purpose of this review of the literature (ROL) is to examine a variety of health system, genetic and cultural barriers in the Puerto Rican community which have created disparities in asthma care and outcomes among adult and pediatric Hispanic populations. In addition, this ROL describes several culturally sensitive, community-based educational interventions which can be used as a framework for future projects to improved asthma outcomes. Databases searched included Medline, PubMED, EBSCOhost, PsycINFO, CINAHL, Google Scholar and ERIC. Papers published in English from January 1990 to January 2012 were reviewed. Health system policies, insurer compensation patterns, clinician attitudes and cultural values/folk remedies in the Puerto Rican community represent barriers to effective asthma management, the use of controller medication and the implementation of educational interventions. In addition, genetic factors involving the beta-2 adrenergic receptor gene, which impair the response to albuterol, appear to contribute to poorer outcomes in Puerto Rican asthmatics. In contrast, several comprehensive, community-based, culturally sensitive educational interventions such as Controlling Asthma in American Cities Project (CAACP), the Racial and Ethnic Approach to Community Health in the US Program and Healthy Hoops programs (REACH) have been described. We believe that culturally sensitive community-based asthma education programs can serve as models for programs targeted toward Puerto Ricans to help decrease asthma morbidity. Moreover, greater sensitivity to Puerto Rican mores and folk remedies on the part of healthcare providers may improve the patient-clinician rapport and, hence, asthma outcomes. Finally, given ethnically based differences in pharmacogenomics, clinical trials targeting the Puerto Rican population may help to better define optimal asthma medication regimens in this ethnic group.

Twins' risk of childhood asthma mediated by gestational age and birthweight.

Children born with low gestational age (GA) or low birthweight (BW) are at increased risk of asthma. Twins as compared to singletons are on average more likely to be born with lower GA and BW and have been hypothesized to comprise a high-risk population for asthma. Many previous studies have not accounted for potential confounders or mediators. To investigate the association between twinship and childhood asthma or early life wheeze and identify potential mediators, such as GA/BW. The study population consisted of two cohorts including all children born in Sweden from 1 January 1993 to 1 June 2001 (n = 756,363 singletons, n = 22,478 twins) and 1 July 2005 to 31 December 2009 (n = 456,239 singletons, n = 12,872 twins). Asthma was defined using validated register-based outcomes of diagnosis or medication. The data were analysed using logistic (older cohort) and Cox regression (younger cohort). Adjusted models incorporated potential confounding or mediating factors including gestational age and birthweight. In the younger cohort, the crude hazard ratio (HR) of asthma medication after 1.5 years of age was 1.12 (95% CI 1.01-1.23), and fully adjusted HR was 0.80, 95% CI 0.72-0.89. Crude HR of asthma diagnosis in the same age group was 1.14 (95% CI 0.99-1.30), fully adjusted 0.78 (0.68-0.98). Adjusted analyses in the older group yielded similar results. Twins were at significantly higher unadjusted risk of asthma or early life wheeze compared to singletons in the younger, but not in the older cohort. Associations attenuated following adjustment for GA/BW, suggesting that GA/BW mediates the effect of twinship on asthma risk. After adjustments, twins were at lower risk of asthma outcomes, possibly due to unmeasured confounding. © 2015 John Wiley & Sons Ltd.

Advances in Pediatric Asthma in 2010: Addressing the Major Issues

Last year’s Advances in Pediatric Asthma concluded with the following statement “If we can close these [remaining] gaps through better communication, improvements in the health care system and new insights into treatment, we will move closer to better methods to intervene early in the course of the disease and induce clinical remission as quickly as possible in most children”. This year’s summary will focus on recent advances in pediatric asthma that take steps moving forward as reported in Journal of Allergy and Clinical Immunology publications in 2010. Some of those recent reports show us how to improve asthma management through steps to better understand the natural history of asthma, individualize asthma care, reduce asthma exacerbations, manage inner city asthma, and some potential new ways to use available medications to improve asthma control. It is clear that we have made many significant gains in managing asthma in children but we have a ways to go to prevent asthma exacerbations, alter the natural history of the disease, and to reduce health disparities in asthma care. Perhaps new directions in personalized medicine and improved health care access and communication will help maintain steady progress in alleviating the burden of this disease in children, especially young children.

Home-based, multifaceted interventions have been effective in reducing asthma morbidity in children. However, identification of independent components that contribute to outcomes and delineating effectiveness by level of asthma symptoms would help to refine the intervention and target appropriate populations. A community health educator led asthma intervention implemented in a low-income African-American neighborhood included asthma management education, individually tailored low-cost asthma home trigger remediation, and referrals to social and medical agencies, when appropriate. Changes in asthma morbidity measures were assessed in relation to implementation of individual intervention components using multivariable logistic regression. Among the 218 children who completed the year-long program, there were significant reductions in measures of asthma morbidity, including symptoms, urgent care visits, emergency department (ED) visits, hospitalizations, missed school days, and missed work days for caretakers. We also found significant decreases in the prevalence of many home asthma triggers and improvements in asthma management practices. Improvement in caretaker's ability to manage the child's asthma was associated with reduction in ED visits for asthma and uncontrolled asthma. Specific home interventions, such as repair of water leaks and reduced exposure to plants, dust, clutter and stuffed toys, may be related to reduction in asthma morbidity. This program was effective in reducing asthma morbidity in low-income African-American children and identified specific interventions as possible areas to target in future projects. Furthermore, the intervention was useful in children with persistent asthma symptoms as well as those with less frequent asthma exacerbations.

To examine national trends in the receipt of asthma action plans, an intervention recommended by the National Asthma Education and Prevention Program guidelines. We used data from the sample child component of the National Health Interview Survey from 2002, 2003, 2008, and 2013 to examine the percentage of children 2-17 years of age with asthma (n = 3714) that have ever received an asthma action plan. Bivariate and multivariate (with adjustment for sociodemographic characteristics and asthma outcomes consistent with greater disease severity) logistic regressions were conducted to examine trends from 2002 to 2013 and to examine, with 2013 data only, the relationship between having received an asthma action plan and both sociodemographic characteristics and indicators of asthma severity. The percentage of children with asthma that had ever received an asthma action plan increased from 41.7% in 2002 to 50.7% in 2013 (P < .001 for trend). In 2013, a greater percentage of non-Hispanic black (58.4%) than non-Hispanic white (47.4%) children (P = .028), privately insured (56.2%) vs those with public insurance only (46.3%) (P = .016), and users of inhaled preventive asthma medication vs those that did not (P < .001) had ever received an asthma action plan. Adjusted results were similar. The percentage of US children with asthma that had ever received an asthma action plan increased between 2002 and 2013, although one-half had never received an asthma action plan in 2013. Some sociodemographic and asthma severity measures are related to receipt of an asthma action plan. Published by Elsevier Inc.

IL-13 and its genetic variants: effect on current asthma treatments.

Townley, Robert G; Sapkota, Muna; Sapkota, Kiran

2011-12-01

Airway hyperresponsiveness is an essential part of the definition of asthma associated temporally with exposure to allergens, certain respiratory viruses, pollutants such as ozone, and certain organic chemicals. Interleukin-13 (IL-13) is implicated as a central regulator in immunoglobulin E (IgE) synthesis, mucus hypersecretion, airway hyperresponsiveness, and fibrosis. The importance of IL-13 in allergic disorders in humans is supported by consistent associations between tissue IL-13 levels and genetic variants in the IL-13 gene and asthma and related traits. Single-nucleotide polymorphisms in IL-13 are associated with allergic phenotypes in several ethnically diverse populations. Glucocorticoids are anti-inflammatory medications often used as maintenance therapy in acute and chronic asthma; however, some patients with severe asthma are steroid resistant. IL-13 remains elevated in glucocorticoid insensitive asthma but not in glucocorticoid sensitive asthma. Thus targeting IL-13 and its associated receptors may be a therapeutic approach to the treatment of asthma and/or allergy. This review focuses on the role of IL-13 on airway hyperresponsiveness and corticosteroids resistant asthma both preclinically and clinically. © Discovery Medicine

[The Chinese experts' consensus on the evaluation and management of asthma exacerbation].

2018-01-01

Asthma exacerbations can do a lot of harm to the patients and consume large amounts of medical resources. This consensus is based on the domestic and foreign guidelines and literatures to standardize the evaluation and management of asthma exacerbations in China. Asthma exacerbations are characterized by a progressive increase in symptoms of shortness of breath, cough, wheezing or chest tightness and progressive decrease in lung function, and usually require modification of treatment. Recognizing risk factors and triggering factors of asthma exacerbations is helpful for the prevention and long-term management. Evaluation of asthma exacerbations is based on symptoms, lung function, and arterial blood gas. Management is stratified according to the severity of disease. Different regimens to treat asthma exacerbations are discussed in this consensus. Glucocorticoids should be used properly. Overuse of antibiotics should be avoided. Management of life-threatening asthma is discussed separately. Special attention should be paid in some special respects, such as asthma during peri-operation period, gestation period, and childhood. Diagnosis and management of complications are also of great significance and are discussed in details.

Patients with cystic fibrosis (CF) have a higher prevalence of asthma than the background population, however, it is unclear whether heterozygous CF carriers are susceptible to asthma. Given this, a meta-analysis is necessary to determine the veracity of the association of CF heterozygosity with asthma. We screened the medical literature from 1966 to 2015 and performed a meta-analysis to determine the risk of asthma in CF heterozygotes vs. non-carriers. Aggregating data from 15 studies, the odds ratio for asthma in CF heterozygotes compared with non-carriers was significantly elevated at 1.61 (95% CI: 1.18-2.21). When analyzing the studies considered of high quality in which asthma was diagnosed by a physician, the patients were >18years, or study size was ≥500, the trend remained the same, that heterozygous carriers of CF had elevated risk for asthma. The results show that heterozygous carriers for CF have a higher risk of asthma than non-carriers. Copyright © 2016 The Authors. Published by Elsevier B.V. All rights reserved.

Revised guidelines were released in Japan in 2003 for the assessment, treatment, and management of adult asthmatics, and similar guidelines for child asthmatics were released in 2002. We reassessed the severity and possible undertreatment of asthma according to these guidelines in stable asthmatics. We reviewed medical records of 861 well-controlled asthmatic patients who, in April through June 2004 were cared for by 47 pulmonologists at 29 medical centers and 13 asthma clinics in a rural community in the San-in area of Japan. The physician obtained completed medical records about their symptoms and current treatment of the subjects, 726 adult and 135 children (aged 6 years or older) who were in stable condition and had had no exacerbations in the previous 3 months. The severity of asthma and current treatment for each patient were assessed according to the newly revised Japanese guidelines for the assessment, treatment, and management of adult and child asthmatics. In adult and child asthmatics, the percentage of predicted forced expiratory volume at 1 second (FEV1.0) was smaller and has a narrower distribution range than the percentage of predicted peak expiratory flow (PEF). When the severity of asthma was classified according to symptoms alone, 50% and 35% of those classified as mildly asthmatics patients with adults and children, respectively, had moderate to severe airflow limitation. Inhaled corticosteroids were prescribed to 90.6% of adult and 14.9% of child patients. When we compared the treatments that patients were actually receiving against the optimal treatments indexed according to a combined symptoms-FEV1.0 classification, we found that 49% of adult asthmatics were overtreated, 21% were properly treated, and 30% were undertreated. Among children, the respective percentages were 35%, 25%, and 40%. In well-controlled adult and child asthmatics, the severity of asthma is poorly judged when symptoms alone are considered. We suggest that the severity of asthma should be assessed through a combination of symptoms and the measurement of FEV1.0 during office visits. We also suggest that the proper dose of inhaled steroid needed to maintain stable conditions should be judged according to this combined symptoms-FEV1.0 classification.

For successful long-term asthma care, self-management education is a cornerstone. Little is known about associations between patients' interest in education, asthma control and care delivery. We compared patients' characteristics, asthma control and patients' perspective about asthma care in subjects with and without interest in asthma education. Moreover, we assessed reasons, why patients denied participating in asthma education. Baseline data of 223 patients with asthma (age 43 ± 12 years, 38% male, 58% non-smokers, 13% current smokers), who participated in a multicentre longitudinal controlled study, are reported. At baseline, patients completed the Asthma Control Test (ACT), the Patient Assessment Chronic Illness Care questionnaire (PACIC 5A) and stated their interest in an asthma education programme. Overall, 34% of all participants showed uncontrolled asthma. One hundred and twenty-five (56%) patients were interested in education. Compared to patients without interest, they were characterised by male gender (p = 0.013), worse asthma control (p < 0.001), and perception of lower quality of chronic asthma care delivery, in particular lower self-management support (p < 0.001). Main reasons for rejecting asthma education were having sufficient asthma knowledge, having only mild asthma, receiving adequate medical support and lack of time. More than half of the patients were interested in asthma education. Interest was associated with worse asthma control and lower receipt of care according to the Chronic Care Model. Considering these aspects, this approach may help to improve care quality and allow targeting interventions to those patients who are interested in becoming active participants in their care and who might benefit most.

Although recent studies have identified the presence of phenotypic clusters in asthmatic patients, the clinical significance and temporal stability of these clusters have not been explored. Our aim was to examine the clinical relevance and temporal stability of phenotypic clusters in children with asthma. We applied spectral clustering to clinical data from 1041 children with asthma participating in the Childhood Asthma Management Program. Posttreatment randomization follow-up data collected over 48 months were used to determine the effect of these clusters on pulmonary function and treatment response to inhaled anti-inflammatory medication. We found 5 reproducible patient clusters that could be differentiated on the basis of 3 groups of features: atopic burden, degree of airway obstruction, and history of exacerbation. Cluster grouping predicted long-term asthma control, as measured by the need for oral prednisone (P < .0001) or additional controller medications (P = .001), as well as longitudinal differences in pulmonary function (P < .0001). We also found that the 2 clusters with the highest rates of exacerbation had different responses to inhaled corticosteroids when compared with the other clusters. One cluster demonstrated a positive response to both budesonide (P = .02) and nedocromil (P = .01) compared with placebo, whereas the other cluster demonstrated minimal responses to both budesonide (P = .12) and nedocromil (P = .56) compared with placebo. Phenotypic clustering can be used to identify longitudinally consistent and clinically relevant patient subgroups, with implications for targeted therapeutic strategies and clinical trials design.

Adolescents with asthma face problems inherent to this stage in their development, to which the challenges of taking over control of their disease, complying with a daily treatment and regular medical followup are added. Any rejection generated by this may lead to treatment non-adherence and poor asthma control, which brings about problems in family dynamics, made worse by the stress or the emotional distress that this situation causes in caregivers. Identify adjustment profiles and predictors of risk for the well-being of caregivers of pediatric patients with bronchial asthma. Seventy-nine family caregivers of pediatric patients with bronchial asthma. Instruments were used to assess the emotional status (Hospital Anxiety and DepressionScale, HADS) and the perceived level of stress associated with medical care of a pediatric patient (Pediatric Inventory for Parents, PIP). We analyzed the patient's medical outcome measures and the family caregiver's psychological outcome measures regarding their emotional distress and stress. Of all caregivers studied, 34.8% exhibit anxiety symptomatology and moderate perceived stress. Emotional symptomatology correlates positively and significantly with the stress level. The models that best predict emotional distress of caregivers (40-50% of explained variance) include time since diagnosis and patient's treatment burden as stress indicators. The presence of stress resulting from care, time of exposure and burden of treatments associated with the disease are identified as the main predictors of risk for the well-being of caregivers.

Asthma is a heterogeneous disease characterized by multiple phenotypes. Treatment of patients with severe disease can be challenging. Predictive biomarkers are measurable characteristics that reflect the underlying pathophysiology of asthma and can identify patients that are likely to respond to a given therapy. This review discusses current knowledge regarding predictive biomarkers in asthma. Recent trials evaluating biologic therapies targeting IgE, IL-5, IL-13, and IL-4 have utilized predictive biomarkers to identify patients who might benefit from treatment. Other work has suggested that using composite biomarkers may offer enhanced predictive capabilities in tailoring asthma therapy. Multiple biomarkers including sputum eosinophil count, blood eosinophil count, fractional concentration of nitric oxide in exhaled breath (FeNO), and serum periostin have been used to identify which patients will respond to targeted asthma medications. Further work is needed to integrate predictive biomarkers into clinical practice.

The purpose of this research is to gain an understanding of the asthma perceptions of older adults and identify gaps in their asthma knowledge. In regional New South Wales, Australia, a stratified, random sample of 4066 adults, aged 55 years and over, both with and without an asthma diagnosis, completed a survey based on the Health Belief Model about asthma knowledge and perceptions. Almost half of the sample had experienced symptoms of breathlessness in the past four weeks. Breathlessness was a predictor of lower health ratings and poorer mood. Older adults reported low susceptibility to developing asthma. The sample demonstrated poor knowledge of key asthma symptoms including shortness of breath, tightness in the chest and a cough at night. There is a general lack of asthma awareness in this age group. This could result in not seeking medical help, and thus a reduced quality of life. Older adults should be made aware of key symptoms and the prevalence of asthma in the older adult population, and be empowered to take control of their respiratory health. Audience segmentation for an intervention should be based on recent experience of breathlessness and asthma diagnosis. Copyright © 2013 Elsevier Ireland Ltd. All rights reserved.

Long-term prognosis of adult-onset asthma is poorly known. To evaluate 12-year prognosis of adult-onset asthma and the factors associated with disease prognosis. Seinäjoki Adult-onset Asthma Study (SAAS) is a 12-year real-life single-center follow-up study of new-onset asthma diagnosed at adult age and treated in primary and specialized care. Remission was defined by no symptoms and no asthma medication use for 6 months. Asthma control was evaluated according to Global Initiative for Asthma 2010. Factors associated with current asthma control were analyzed by multinomial multivariate logistic regression. A total of 203 patients (79% of the baseline population) were followed for 12 years. Remission occurred in 6 (3%) patients. In 34% asthma was controlled, in 36% it was partially controlled and in 30% uncontrolled. Uncontrolled asthma was predicted by elevated body-mass index at baseline, smoking (pack-years) and current allergic or persistent rhinitis. Elevated blood eosinophils and good lung function (FEV1) at baseline protected from uncontrolled asthma. In contrast, gender, age at the onset or baseline symptoms (Airways Questionnaire 20) were not significant predictors of uncontrolled disease. During a 12-year follow-up, remission of adult-onset asthma was rare occurring in only 3% of patients. The majority of patients (66%) presented either with uncontrolled or partially controlled asthma. This study is registered at ClinicalTrials.gov with identifier number NCT02733016.

An association between salmeterol use and serious asthma episodes or asthma-related mortality has been noted in 2 clinical trials; however, a causal relationship has not been established. To date, observational studies have not replicated this finding. To examine the relationship between number of prescriptions dispensed of salmeterol-containing products and inhaled corticosteroid (ICS)-containing products and the rates of asthma-related hospitalizations and mortality in the United States. In this ecologic study, annual age-adjusted rates of asthma-related hospitalization and asthma-related mortality from US population-based sources were graphed alongside annual number of prescriptions dispensed of salmeterol- and ICS-containing products by year from 1991 to 2004. We computed the Spearman rank correlations between number of prescriptions dispensed and serious events (asthma-related hospitalization rate, number of hospitalizations, asthma-related mortality rate, and number of asthma deaths). During more than 14 years, while number of prescriptions dispensed of salmeterol-containing and ICS-containing products increased, age-adjusted asthma-related mortality rates declined and asthma-related hospitalization rates remained relatively stable. The number of asthma-related deaths has decreased steadily since the mid-1990s. This study provides population-level evidence that asthma-related death rates declined and asthma-related hospitalization rates remained relatively constant for more than 14 years during a period of improvements in asthma management per treatment guidelines, including increased use of maintenance medications, such as ICSs and salmeterol.

Most asthma patients prescribed maintenance asthma therapies still experience periods of asthma worsenings characterized by daytime or nighttime symptoms, or an increased need for rescue medication. In fact, these episodes are highly prevalent even in patients with well-controlled disease. Published literature suggests that asthma worsenings likely represent a window of opportunity during which patients could intervene early to prevent exacerbations or further deterioration of asthma symptoms. However, current evidence suggests that most patients fail to respond or to self-manage appropriately during these periods. To address the issue of asthma worsenings, an interdisciplinary committee of respirologists, allergists, family physicians, pharmacists and certified asthma educators from across Canada developed a practical definition of asthma worsenings and provided approaches to the prevention and management of these episodes based on current literature. To date, combination inhaled corticosteroid/long-acting beta-agonist therapy, particularly single inhaler maintenance and reliever therapy, appears to be an effective strategy for preventing asthma worsenings and exacerbations. Addressing the potential barriers to appropriate patient self-management of asthma worsenings, such as failure to adequately identify and respond to worsenings, low expectations for controlling asthma, low health literacy and poor patient-health care professional communication, are also critical to the successful prevention and management of these episodes. Finally, an interdisciplinary team approach involving patients and their families, certified asthma educators, primary care physicians, pharmacists and specialists is likely to have the greatest impact on the identification, prevention and management of asthma worsenings.

Background Inappropriate prescribing and misuse of asthma medication, have been identified as potentially preventable factors linked to asthma exacerbations and deaths. A recent report by the National Review of Asthma Deaths drew attention to the excessive prescribing of reliever medication, and under-prescribing of controlled medication in the United-Kingdom (UK). The inappropriate prescribing of long-acting beta agonist (LABA) bronchodilator inhalers, as either a monotherapy or without inhaled corticosteroids (ICS) has been highlighted as a major preventable factor of asthma exacerbations and deaths. To determine whether the prevalence of inappropriate LABA therapy use in asthma in the UK and in France has changed over time. Methods Two interval, parallel, population-based cohorts (2007 and 2013), were developed in each country, utilising the UK Optimum Patient Care Research Database and the French Permanent Beneficiaries Sample database. Following inclusion, patients aged 6–40 years were studied over a 12-month period. The use of LABAs without ICS, and ≥2-fold higher use of LABA compared with ICS were investigated. Analyses were stratified by age groups: children (6–13 years) and adults (14–40 years). Results Overall, 39,743 UK and 4,910 French patients were included in 2007 and 14,036 and 5,657 in 2013. In 2013, LABA use without ICS occurred in 0.1% and 1.5% of UK and French adults respectively. This was a marked reduction from 2007 UK and French figures of 0.4% and 2.6% respectively (P<0.05 for both). Excessive use of LABA relative to ICS occurred in 0.2% of UK adults and in 0.7% of French adults in 2013. These percentages represented a decrease from the 2007 figures of 0.6% and 1.4% for UK (P=0.29) and France (P=0.003), respectively. In 2007, LABA inappropriate use was more frequent in French than UK asthmatic children (P<0.0001), but showed a downward trend by time in both countries (0.1% in 2013 in both countries). Conclusions Our study suggests that despite noticeable differences in the healthcare systems between these two countries, there has been a marked reduction of inappropriate LABA use in asthma in recent years. Despite this, 7,480 and 55,650 patients with asthma in the UK and France respectively, were inappropriately prescribed LABAs, highlighting the necessity of corrective measures to reduce the asthma-associated burden.

The incidence of occupational asthma (OA) is increasing worldwide. In this study, we first aimed to document the rate of diagnosis of OA among patients who were referred to our clinic from the Social Security Institution and the factors that affected diagnosis; secondly, we aimed to assess the consistency of the medical and legal diagnoses. The study involved 132 consecutive patients who were referred to our clinic for the evaluation of OA between 2010 and 2015. Detailed workplace history, the tools used in the diagnosis such as peak expiratory flow (PEF) monitoring and bronchial provocation tests, and the final medical diagnosis were recorded from case files. Asthma was diagnosed in 75% (n = 99) of the patients. Among them, 22.2% were diagnosed as having OA. The diagnosis was confirmed by serial PEF measurements, non-specific bronchial hyperreactivity assessment or both of the tests both at work and off-work periods. OA diagnosis was mostly established in active workers (72.7%). The legal diagnosis period was completed in 54.5% of these 22 patients, and 50% (n = 11) were officially diagnosed as having OA with a 91.6% concordance with medical diagnosis. This study verifies the importance of diagnosing asthma correctly as a first step in the evaluation of OA. Diagnostic tests other than specific provocation tests could be preferential in patients who still work in the same field. We believe that cooperation with the patient's occupational physician and adequate recognition of the work environment will improve the consistency of legal and medical diagnoses.

Objective: I sought to determine if a combination of acupuncture and guided imagery could augment the conventional medical management of moderately severe or severe asthma. Design: This was an early-phase study with a convenience sample of self-selecting patients compared with self—year before, during treatment, and one year after treatment. Setting: Patients were recruited from an outpatient practice. Patients: All participants were adults with moderately severe or severe asthma (class 3 or 4). Interventions: The study employed acupuncture and guided imagery/meditation for a 24-week period. Main Outcome Measures: The main outcome measures were number of days of hospitalization, number of Emergency Department (ED) visits, number of physician visits, days per year taking steroids, puffs per week of inhaled β-agonists, FVC (forced vital capacity), FEV1 (forced expiratory volume in the first second), and FEF25-75 (forced expiratory flow between 25% and 75% of the FVC). Results: With the addition of acupuncture and guided imagery to conventional medical management, members of the study group experienced improvement. The number of hospitalized days and the number of ED visits not leading to hospitalizations decreased, as did number of medical visits and total days taking oral corticosteroids. Parameters of respiratory function improved despite reduced use of inhaled β-agonists. Conclusion: With acupuncture and guided imagery and meditation together, a self-selecting group of patients with moderately severe or severe asthma experienced improvement in respiratory function, taking less medication than before and having fewer emergencies and hospitalizations at a lower cost of care.

Negotiated treatment plans are increasingly recommended in asthma clinical care. However, limited data are available to indicate whether this more patient-engaged process results in improved health outcomes. The aim of this study was to determine the associations between the presence of a negotiated treatment plan and the outcomes related to adherence to the medical regimen, symptom control, and health care use. The focus of the study was on women, the subgroup of adult patients, who are most vulnerable for negative asthma outcomes. Data were collected by telephone interview and medical record review from 808 women diagnosed with asthma at baseline, first year, and second year follow-up. Associations were examined between the presence of a negotiated treatment plan at baseline and subsequent asthma outcomes. Women with a negotiated treatment plan reported more adherent to prescribed asthma medicines (odds ratio (OR) = 2.41, 95% confidence interval (CI) = (1.82, 3.19)) and those with a plan and using oral steroids at baseline had less oral steroid use at follow-up (OR = 0.21, 95% CI = (0.05, 0.93)). Women with a negotiated plan also had more days (17%, 95% CI = (8, 27)) and nights (31%, 95% CI = (16, 48)) with symptoms than those without such a plan. No differences in hospitalizations, emergency department visits, or urgent physician office visits were noted between the groups. Patients with higher education levels were more likely to have a negotiated treatment plan. Negotiated treatment plans appear to have achieved greater adherence to prescribed asthma medicines and less need for oral steroids but were not related to fewer symptoms of asthma or reductions in urgent health care use. Additional strategies may be needed to reduce symptom and health services utilization outcomes.

Tobacco smoke exposure increases breathing problems of children. Texas Children's Health Plan is a Managed Medicaid and Children's Health Insurance Program (CHIP) managed care provider. The aim of this study is to determine associations among tobacco smoke exposure, asthma prevalence, and asthma health-care utilization. Texas Children's Health Plan conducts an annual survey of members who have a physician visit. Questions were added to the survey in March 2010 about asthma and tobacco smoke exposure. Survey results for children < 18 years of age were matched to health plan claims data for the 12 months following the date of the physician visit. A total of 22,470 parents of unique members/patients from birth to < 18 years of age participated in the survey. More whites than African Americans or Hispanics report that the child's mother is a smoker (19.5% vs 9.1% and vs 2.3%, respectively; P < .001). Compared with children whose mother does not smoke, parent report of asthma diagnosis and claims for dispensing of short-acting beta agonist medication are greater if the mother is a smoker (adjusted OR, 1.20 [95% CI, 1.03-1.40] and 1.24 [95% CI, 1.08-1.42], respectively). In contrast to Medicaid, in which there are no out-of-pocket costs, the CHIP line of business requires copays for ED visits. ED visits are influenced by maternal smoking only in the CHIP line of business (adjusted OR, 4.40; 95% CI, 1.69-11.44). Maternal smoking increases risk for asthma diagnosis and prescription of asthma quick relief medication. Maternal smoking predicted asthma-related ED visits only for the CHIP line of business.

Use of oral short-acting beta 2-agonist (SABA) persists in non-resource poor countries despite concerns for its lower efficacy and safety. Utilisation and reasons for such use is needed to support the effort to discourage the use of oral SABA in asthma. This study examined the frequency of oral short-acting Beta 2-agonist (SABA) usage in the management of asthma in primary care and determined correlates of its usage. Data used were from the 2014 National Medical Care Survey in Malaysia, a nationally representative survey of primary care encounters (weighted n = 325818). Using methods of analysis of data for complex surveys, we determined the frequency of asthma diagnosis in primary care and the rate of asthma medication prescription, which includes oral SABA. Multivariate logistic regression models were built to assess associations with the prescription of oral SABA. A weighted estimate of 9241 encounters presented to primary care with asthma in 2014. The mean age of the patients was 39.1 years. The rate of oral SABA, oral steroids, inhaled SABA and inhaled corticosteroids prescriptions were 33, 33, 50 and 23 per 100 asthma encounters, respectively. It was most commonly used in patients with the age ranged between 20 to less than 40 years. Logistic regression models showed that there was a higher odds of oral SABA usage in the presence of respiratory infection, prescription of oral corticosteroids and in the private sector. Oral SABA use in asthma is found to be common in a non- resource poor setting and its use could be attributed to a preference for oral medicines along undesirable clinical practices within a fragmented health system.

Accurate identification of paediatric patients with severe asthma is essential for an adequate management of the disease. However, criteria for defining severe asthma and recommendations for control vary among different guidelines. An online survey was conducted to explore expert opinions about the definition and management of severe paediatric asthma. To reach a consensus agreement, a modified Delphi technique was used, and practice guidelines were prepared after the analysis of the results. Eleven paediatric chest disease physicians and allergy specialists with wide expertise in severe asthma responded to the survey. Consensus was reached in 50 out of 65 questions (76.92%). It was considered that a patient has severe asthma if during the previous year they have required 2 or more cycles of oral steroids, required daily treatment with medium doses of inhaled corticosteroids (with other controller medication) or high doses (with or without other controller medication), did not respond to optimised conventional treatment, or if the disease threatened the life of the patient or seriously impairs their quality of life. The definition of severe asthma may also include patients who justifiably use health resources on a regular basis, or have psychosocial or environmental factors impeding control. For monitoring, the use of questionnaires designed specifically for paediatric population, such as CAN or ACT, is recommended. As regards treatment, the use of omalizumab should be considered prior to the use of oral corticosteroids. This paper provides consensus recommendations that may be useful in the management of severe paediatric asthma. Copyright © 2015 Asociación Española de Pediatría. Published by Elsevier España, S.L.U.

Asthma is the most common chronic lower respiratory disease in childhood throughout the world. Several guidelines and/or consensus documents are available to support medical decisions on pediatric asthma. Although there is no doubt that the use of common systematic approaches for management can considerably improve outcomes, dissemination and implementation of these are still major challenges. Consequently, the International Collaboration in Asthma, Allergy and Immunology (iCAALL), recently formed by the EAACI, AAAAI, ACAAI and WAO, has decided to propose an International Consensus on (ICON) Pediatric Asthma. The purpose of this document is to highlight the key messages that are common to many of the existing guidelines, while critically reviewing and commenting on any differences, thus providing a concise reference. The principles of pediatric asthma management are generally accepted. Overall, the treatment goal is disease control. In order to achieve this, patients and their parents should be educated to optimally manage the disease, in collaboration with health care professionals. Identification and avoidance of triggers is also of significant importance. Assessment and monitoring should be performed regularly to re-evaluate and fine-tune treatment. Pharmacotherapy is the cornerstone of treatment. The optimal use of medication can, in most cases, help patients control symptoms and reduce the risk for future morbidity. The management of exacerbations is a major consideration, independent from chronic treatment. There is a trend towards considering phenotype specific treatment choices; however this goal has not yet been achieved. PMID:22702533

BACKGROUND--The aim was to establish a continuing district based confidential enquiry into deaths from asthma. METHODS--A confidential enquiry was conducted in an English health district. Subjects comprised 24 residents of the Norwich health district aged between 16 and 65 years who had died between 1988 and 1991 with asthma as the principal cause of death. RESULTS--Twenty one of the patients (88%) died away from hospital. Overall the routine asthma management was appropriate in all respects in only four patients. In five cases the drug treatment was considered inappropriate, in 10 cases (42%) there was no written evidence that the patient had received advice and education, and only six cases had a written management plan. In 17 patients (71%) the fatal attack of asthma developed rapidly (in under three hours). The medical care during the final attack was found to have been inappropriate in six cases. Seventeen cases (71%) had psychological or social factors that were considered to have been of potential importance. CONCLUSIONS--This study has shown the feasibility of organising a confidential enquiry into asthma deaths within a health district. The distinguishing features of such an enquiry are that it is continuing, that the quality of care given to those patients who died is compared against a recognised standard, and that there is a structured system for feeding back the conclusions of the enquiry to the local medical community.

Achieving asthma control is central to optimising patient quality of life and clinical outcome. Contemporary models of chronic disease management across a variety of countries point to the importance of micro, meso and macro level influences on patient care and outcome. However, asthma outcomes research has almost invariably concentrated on identifying and addressing patient predictors. Little is known about higher level organisational influences. This paper explores the contribution of organisational factors on poor asthma control, allowing for patient factors, at three organisational levels: the individual patient, local service deliverers, and strategic regional providers. Prospective cross-sectional observational cohort study of 64,929 people with asthma from 1205 primary care practices spread throughout the United Kingdom (UK). Patient clinical data were recorded during a routine asthma review. Data were analysed using simple descriptive, multiple regression and complex multi-level modelling techniques, accounting for practice clustering of patients. Poor asthma control was associated with areas of higher deprivation [regression coefficient 0.026 (95% confidence intervals 0.006; 0.046)] and urban practice [-0.155 (-0.275; -0.035)] but not all local and regional variation was explained by the data. In contrast, patient level predictors of poor control were: short acting bronchodilator overuse [2.129 (2.091; 2.164)], days-off due to asthma [1.203 (1.148; 1.258)], PEFR<80 [0.76 (0.666; 0.854)], non-use of a self-management plan (SMP) [0.554 (0.515; 0.593)], poor inhaler technique [0.53 (0.475; 0.585)], poor medication compliance [0.385 (-0.007; 0.777)], and gender [0.314 (0.281; 0.347)]. Pattern of medication use, smoking history, age, body mass index (BMI), and health service resource use were also significant factors for predicting control. Targeting of health service resource requires knowledge of the factors associated with poor control of asthma symptoms. In the UK the contribution of local and regional structures appears minimal in explaining variation in asthma outcomes. However, unexplained variation in the data suggests other unrecorded factors may play a part. While patient personal characteristics (including self-management plan use, inhaler technique, medication compliance) appear to be the predominant influence the complex nature of the disease means that some, perhaps more subtle, influences are affecting the variability at all levels and this variance needs to be explored. Further research in other international contexts is required to identify the likely applicability of these findings to other health care systems. Copyright © 2011 Elsevier Ltd. All rights reserved.

 We sought feedback from elderly patients living with asthma to understand their experience with assuming self-management roles for their asthma in order to inform the design and implementation of a primary care-based strategy that could best support their asthma control. We held six focus groups with a total of 31 English- and Spanish-speaking older adults with a current diagnosis of asthma. Focus groups addressed the effect of asthma on patients' lives and self-management strategies. Transcripts were analyzed using constant comparative techniques. Asthma exerted a consistent effect on patients' physical and psychological well-being. Common barriers to self-care included misuse of controller medications and uncertainty whether shortness of breath, fatigue, and cough were due to their asthma or some other chronic illness. Patients developed coping strategies to continue with daily activities even when experiencing symptoms, but did not recognize attainable asthma quality of life. Asthma had a distinct impact on elderly adults' quality of life; due to their longstanding history with this condition, many patients had accepted these symptoms as a "new normal." Developing strategies to reorient patients' perceptions of the possibilities for managing their illness will be critical to the success of asthma self-management support programs specific to older adults.

Asthma is an important and serious public health problem in Puerto Rico; however, very few studies measuring the association between health care utilization and asthma control levels in adult asthma patients in Puerto Rico have been done. This study is secondary analysis of an observational and cross-sectional database generated by the Latin American Asthma Insights and Management (LA AIM) survey. Our sub-sample consisted of adults 18 years or older living with asthma, representing a total of 343 individuals. This study determined the numbers of ambulatory physician visits, emergency visits to a physician or an emergency room, and hospitalizations that took place the 12 months prior to the survey. Patients were characterized as having well-controlled, partly controlled, or uncontrolled asthma. Descriptive and inferential statistics were performed to detect differences in the mean and number of events for physician visits, emergency visits, and hospitalizations by asthma control groups. After adjusting for age, sex, and chronic health conditions (other than asthma), adult asthma patients with controlled asthma had 92.0% fewer physician visits, 82.5% fewer emergency visits, and 92.2% fewer hospitalizations than did those with uncontrolled asthma. Interventions geared toward controlling asthma symptoms and clinical manifestations in adults asthma patients-which interventions might include strategies for controlling environmental risk factors, increasing patient and family education with regard to asthma management, and boosting the use of appropriate and effective medications-may have significant potential in terms of reducing the direct and indirect costs of asthma, costs that have a critical impact on the whole health care system.

Asthma prevalence may be reduced in large families. The hygiene hypothesis suggests that older siblings protect their younger siblings from asthma through a modulating effect on the still-maturing immune system. If the hygiene hypothesis is correct, asthma prevalence should be inversely related to birth order. The objective of this study was to examine the relationship between asthma prevalence, and family size and birth order. The medical records of 531,116 Israeli military conscripts were reviewed. The association between number of children in the family and the prevalence of asthma, and between birth order and the prevalence of asthma was assessed. Odds ratios for asthma by birth order and family size, adjusted for each other, were calculated. Asthma was diagnosed in 26,833 male subjects (8.6%) and 15,079 female subjects (6.9%). Asthma prevalence was inversely related to the number of children in the family (p < 0.001). Among subjects who were the only child in the family, the prevalence of asthma was 7.3%. The prevalence increased to 8.95% among subjects from families with three siblings, and then progressively decreased as the number of siblings increased, and reached a trough of 0.58% in conscripts from families of 15 to 20 siblings. Asthma prevalence was similar for all birth orders. In families with four or more children, asthma prevalence is inversely related to the number of children in the family. Asthma prevalence is similar for all birth orders. The similar asthma prevalence for all birth orders challenges the hygiene hypothesis as the mechanism for the decreased asthma prevalence in large families.

Research has demonstrated high comorbidity between asthma and panic disorder (PD). Less is known about the relationship between asthma and the Latino cultural idiom of distress of ataques de nervios, as well as the role that psychosocial stressors play. The current study tested the hypotheses that Latino asthma patients who experience PD, ataques de nervios, and/or asthma-related death of a loved one endorse greater psychological triggers of asthma, greater perceived impact of asthma triggers, and greater difficulty controlling such triggers than do those without these conditions. Data originated from an interview conducted prior to a randomized controlled trial in which 292 Latino adults with self-reported asthma were recruited from outpatient clinics in the Bronx, NY. The PRIME-MD Patient Health Questionnaire (PHQ) was used to screen for PD symptoms, while the Structured Clinical Interview for DSM-IV (SCID-I) was used to confirm diagnosis of PD. Lifetime history of ataques de nervios and asthma-related death of a loved one were based upon self-report. Asthma triggers were examined using the Asthma Trigger Inventory (ATI). PD, ataques de nervios, and asthma-related death of a loved one each predicted a higher frequency of psychological asthma triggers, controlling for gender and comorbid medical conditions. Participants with PD also reported greater impact of asthma triggers than those without PD, while no significant differences in perceived control were observed. Providers should screen for PD, ataques de nervios, and asthma-related death of a loved one in Latino asthma patients, given their observed association with emotionally triggered asthma.

Women with endometriosis frequently suffer from autoimmune inflammatory diseases, allergies and asthma. This study was conducted to examine whether the prevalence of allergies is higher in patients with endometriosis than in the control group, and to show potential correlation with endometriosis stages. We evaluated the medical files of 501 women with laparoscopically-diagnosed endometriosis and 188 women without endometriosis enrolled in Yale University Hospital. Main outcome measures used were allergy on medications, complaints of sinus or perennial allergic rhinitis, asthma, family history of allergic disease, and correlation with stages of endometriosis. Our results indicated that the overall risk of women with endometriosis and positive history of allergies was 4.28 (95% CI, 2.9-6.3) (p < 0.001). Significant excesses were identified for medications, sinus allergic rhinitis, and asthma; also, women with endometriosis were significantly more likely to report a positive family history of allergies. Overall, our study indicated a link between endometriosis and increased risk of allergic autoimmune disorders that should further be explored.

We investigated whether hospital-based specialist asthma nurses improved recognition and self-treatment of asthma episodes by patients followed up after attending accident and emergency departments (A&E) for asthma exacerbations. We carried out a randomized prospective controlled trial of adult asthma self-management, following a hospital outpatient nurse consultation in two outer-London District General Hospitals (secondary care centres). The study included 211 adults, over 18 years old (mean age 40 years) who attended for asthma in two accident and emergency departments over 13 months. One hundred and eight evaluable patients were randomized into the control group who continued with their usual medical treatment and were not offered any intervention during the study period. One hundred and three evaluable patients were randomized into the intervention group. They were offered three 6-weekly outpatient appointments with one of two specialist asthma nurses for a structured asthma consultation, after attendance at the accident and emergency department. Following assessment of their asthma treatment and control, the nurses advised patients, through the use of self-management-plans, how to recognize and manage uncontrolled asthma and when to seek medical assistance. Medication and inhaler device type were altered if necessary The primary outcome was patient reported self-management of asthma exacerbations for 6 months. Secondary outcomes were assessed at baseline, 3 months and 6 months. These included home peak flow and symptom diaries, structured telephone questionnaires and audit of general practitioner records to determine utilization of services (6 months before and after A&E). Data were analysed on an intention to treat basis by multiple and logistic regression. The intervention group increased their use of inhaled topical steroids in 31/61 (51%) vs. 15/70 (21%) attacks in controls (OR 3.91 CI 1.8-8.4, P<0.001) and their use of rescue medication in 54/61 (89%) severe attacks vs. 53/70 (76%) controls (OR 2.88 CI 1.1-7.9, P<0.05). Intervention patients had significantly higher (mean 20.1 l min(-1); CI 0.4-39.7; P<0.05) and less variable PEF and significantly lower and less variable symptom scores 6 months after entry. Thirty-four percent of intervention patients vs. 42% controls had severe attacks (61 and 70 respectively, OR 0.96 CI 0.7-1.4) during the 6 months. Intervention patients had fewer days off work than controls in the first 3 months (NS) but similar days off during the 6-month period. Intervention patients had fewer episodes away from work in the first (0.34 vs. 0.54, P = 0.08) and the second 3 months (0.25 vs. 0.30, NS) than the controls. Over 80% of the patients records were audited by their general practitioners; the active group had less routine consultations with the doctor (P = 0.03) and practice nurse (P = 0.03), less consultations for uncontrolled episodes (P = 0.06) and less hospital visits (NS) than the controls. Hospital-based specialist nurses reduced asthma morbidity by improving patient self-management behaviour in acute attacks leading to reduced symptoms, improved lung function, less time off work and fewer consultations with health professionals.

The burden of asthma falls disproportionately on children from New Zealand's Pacific communities. Guidelines recommend pictorial resources but these have not been evaluated in this population. Evaluate a pictorial asthma medication plan focusing on regular 'everyday' inhaler use and a signs and symptoms sheet for Pacific children; the primary outcome measure was continued use of resources after 6 months. Resources were provided to families with face-to-face education at a general practice or inpatient setting in West Auckland. A questionnaire about the resources was completed after 6 weeks, and an audit regarding use after 6 months. Data from 48 children were analysed (Samoan, n=31); 45 English and 22 first language versions (Samoan, Tongan, Tuvaluan) were used; median time to questionnaire completion was 48 days. The pictorial asthma medication plan was acceptable to families, effective at reinforcing the importance of 'everyday' inhalers, and a reminder for regular use; the signs and symptoms sheets were informative and improved self-efficacy; 93% of families were using the resources after 6 months. An increase in 'everyday' inhaler use was observed after education. The resources were effective at improving inhaler knowledge and supporting symptom recognition. A 'less-is-more' approach, pictorial format, and first language availability are characteristics that may benefit other ethnicities.

We conducted a pragmatic randomized controlled trial to test the effectiveness of an asthma question prompt list with video intervention to increase youth question-asking and provider education during visits. English or Spanish-speaking youth ages 11-17 with persistent asthma and their parents were enrolled from four rural and suburban pediatric clinics. Youth were randomized to the intervention or usual care groups. Intervention group adolescents watched the video on an iPad and then completed an asthma question prompt list before their visits. Generalized estimating equations were used to analyze the data. Forty providers and 359 patients participated. Intervention group youth were significantly more likely to ask one or more questions about medications, triggers, and environmental control than usual care youth. Providers were significantly more likely to educate intervention group youth about rescue medications, triggers, and environmental control. Intervention group caregivers were not significantly more likely to ask questions. The intervention increased youth question-asking and provider education about medications, triggers, and environmental control. The intervention did not impact caregiver question-asking. Providers/practices should consider having youth complete question prompt lists and watch the video with their parents before visits to increase youth question-asking during visits.

Current concepts of severe asthma

Raundhal, Mahesh; Oriss, Timothy B.; Ray, Prabir; Wenzel, Sally E.

2016-01-01

The term asthma encompasses a disease spectrum with mild to very severe disease phenotypes whose traditional common characteristic is reversible airflow limitation. Unlike milder disease, severe asthma is poorly controlled by the current standard of care. Ongoing studies using advanced molecular and immunological tools along with improved clinical classification show that severe asthma does not identify a specific patient phenotype, but rather includes patients with constant medical needs, whose pathobiologic and clinical characteristics vary widely. Accordingly, in recent clinical trials, therapies guided by specific patient characteristics have had better outcomes than previous therapies directed to any subject with a diagnosis of severe asthma. However, there are still significant gaps in our understanding of the full scope of this disease that hinder the development of effective treatments for all severe asthmatics. In this Review, we discuss our current state of knowledge regarding severe asthma, highlighting different molecular and immunological pathways that can be targeted for future therapeutic development.

The UK Refractory Asthma Stratification Programme (RASP-UK) will explore novel biomarker stratification strategies in severe asthma to improve clinical management and accelerate development of new therapies. Prior asthma mechanistic studies have not stratified on inflammatory phenotype and the understanding of pathophysiological mechanisms in asthma without Type 2 cytokine inflammation is limited. RASP-UK will objectively assess adherence to corticosteroids (CS) and examine a novel composite biomarker strategy to optimise CS dose; this will also address what proportion of patients with severe asthma have persistent symptoms without eosinophilic airways inflammation after progressive CS withdrawal. There will be interactive partnership with the pharmaceutical industry to facilitate access to stratified populations for novel therapeutic studies. Published by the BMJ Publishing Group Limited.

Asthma in pregnancy: management strategies.

PubMed

McCallister, Jennifer W

2013-01-01

Asthma is one of the most prevalent chronic medical conditions to complicate pregnancy. With approximately one-third of women experiencing a worsening of control during the course of their pregnancy, identifying those at greatest risk has the potential to improve maternal and fetal outcomes for a large number of pregnancies. Similarly, active management strategies that prioritize asthma control in this vulnerable population can have a far-reaching impact. Demographic characteristics and patient noncompliance place certain populations of pregnant women at increased risk of poor asthma control during pregnancy. In addition, undertreatment and disparities in care of acute exacerbations during pregnancy likely contribute. Targeted educational interventions and treatment algorithms using objective markers of disease activity have shown improved outcomes in asthma control. Active management strategies which focus on identifying patient-specific risk factors, patient and provider education, and targeted treatment interventions can improve asthma care for women during pregnancy.

To examine the reliability and validity of the Family Asthma Management System Scale for low-income African-American children with poor asthma control and caregivers under stress. The FAMSS assesses eight aspects of asthma management from a family systems perspective. Forty-three children, ages 8-13, and caregivers were interviewed with the FAMSS; caregivers completed measures of primary care quality, family functioning, parenting stress, and psychological distress. Children rated their relatedness with the caregiver, and demonstrated inhaler technique. Medical records were reviewed for dates of outpatient visits for asthma. The FAMSS demonstrated good internal consistency. Higher scores were associated with adequate inhaler technique, recent outpatient care, less parenting stress and better family functioning. Higher scores on the Collaborative Relationship with Provider subscale were associated with greater perceived primary care quality. The FAMSS demonstrated relevant associations with asthma management criteria and family functioning for a low-income, African-American sample.

Perinatal and Early Childhood Environmental Factors Influencing Allergic Asthma Immunopathogenesis

2014-01-01

Background The prevalence of asthma has increased dramatically over the past several decades. While hereditary factors are highly important, the rapid rise outstrips the pace of genomic variation. Great emphasis has been placed on potential modifiable early life exposures leading to childhood asthma. Methods We reviewed the recent medical literature for important studies discussing the role of the perinatal and early childhood exposures and the inception of childhood asthma. Results and Discussion Early life exposure to allergens (House dust mite (HDM), furred pets, cockroach, rodent and mold)air pollution (nitrogen dioxide (NO2), ozone (O3), volatile organic compounds (VOCs), and particulate matter (PM)) and viral respiratory tract infections (Respiratory syncytial virus (RSV) and human rhinovirus (hRV)) have been implicated in the development of asthma in high risk children. Conversely, exposure to microbial diversity in the perinatal period may diminish the development of atopy and asthma symptoms. PMID:24952205

A home visiting asthma education program: challenges to program implementation.

This study describes the implementation of a nurse home visiting asthma education program for low-income African American families of young children with asthma. Of 55 families, 71% completed the program consisting of eight lessons. The achievement of learning objectives was predicted by caregiver factors, such as education, presence of father or surrogate father in the household, and safety of the neighborhood, but not by child factors, such as age or severity of asthma as implied by the prescribed asthma medication regimen. Incompatibility between the scheduling needs of the families and the nurse home visitors was a major obstacle in delivering the program on time, despite the flexibility of the nurse home visitors. The authors suggest that future home-based asthma education programs contain a more limited number of home visits but add telephone follow-ups and address the broader needs of low-income families that most likely function as barriers to program success.

Objectives. We examined the association between exposure to violence and asthma among urban children. Methods. We obtained reports from caretakers (n = 851) of violence, negative life events, unwanted memories (rumination), caretaker-perceived stress, and caretaker behaviors (keeping children indoors, smoking, and medication adherence). Outcomes included caretaker-reported wheezing, sleep disruption, interference with play because of asthma, and effects on the caretaker (nights caretaker lost sleep because of child’s asthma). Results. Increased exposure to violence predicted higher number of symptom days (P = .0008) and more nights that caretakers lost sleep (P = .02) in a graded fashion after control for socioeconomic status, housing deterioration, and negative life events. Control for stress and behaviors partially attenuated this gradient, although these variables had little effect on the association between the highest level of exposure to morbidity, which suggests there are other mechanisms. Conclusions. Mechanisms linking violence and asthma morbidity need to be further explored. PMID:15054016

Cockroach allergy and asthma in a 30-year-old man.

A growing body of evidence has implicated allergens derived from cockroaches as an important environmental factor that may aggravate asthma in sensitized persons. We present the case of a 30-year-old man with asthma and a cockroach allergy. Allergy skin testing confirmed hypersensitivity to cockroach extract, and a home visit revealed visual evidence of infestation and the presence of Bla g 1 German cockroach allergen in vacuumed dust. As is typical of patients with a cockroach allergy and asthma, multiple factors in addition to cockroach allergen appeared to aggravate the patient's asthma. A multimodality therapeutic regimen, which included medications as well as cleaning of the home, integrated pest management, and professional application of chemical controls, resulted in substantial clinical improvement. The pathophysiology, epidemiology, and clinical features of cockroach-allergic asthma are reviewed, and an approach to diagnosis and management is suggested. Images Figure 1 Figure 2 PMID:10064555

Asthma is one of the most frequently targeted chronic diseases in the medication therapy management (MTM) programs of the Medicare prescription drug (Part D) benefits. Although racial and ethnic disparities in meeting eligibility criteria for MTM services have been reported, little is known about whether there would be similar disparities among adults with asthma in the United States. Adult patients with asthma (age ≥ 18) from Medical Expenditure Panel Survey (2011-2012) were analyzed. Bivariate analyses were conducted to compare the proportions of patients who would meet Medicare MTM eligibility criteria between non-Hispanic Blacks (Blacks), Hispanics and non-Hispanic Whites (Whites). Survey-weighted logistic regression was performed to adjust for patient characteristics. Main and sensitivity analyses were conducted to cover the entire range of the eligibility thresholds used by Part D plans in 2011-2012. The sample included 4,455 patients with asthma, including 2,294 Whites, 1,218 Blacks, and 943 Hispanics. Blacks and Hispanics had lower proportions of meeting MTM eligibility criteria than did Whites (P < 0.001). According to the main analysis, Blacks and Hispanics had 36% and 32% lower, respectively, likelihood of MTM eligibility than Whites (odds ratio [OR]: 0.64, 95% confidence interval [CI]: 0.45-0.90; OR: 0.68, 95% CI: 0.47-0.98, respectively). Similar results were obtained in sensitivity analyses. There are racial and ethnic disparities in meeting Medicare Part D MTM eligibility criteria among adult patients with asthma. Future studies should examine the implications of such disparities on health outcomes of patients with asthma and explore alternative MTM eligibility criteria.

With the increasing incidence of asthma, there is increasing concern over environmental exposures that may trigger asthma exacerbations. Blooms of the marine microalgae, Karenia brevis, cause red tides (or harmful algal blooms) annually throughout the Gulf of Mexico. K brevis produces highly potent natural polyether toxins, called brevetoxins, which are sodium channel blockers, and possibly histamine activators. In experimental animals, brevetoxins cause significant bronchoconstriction. In humans, a significant increase in self-reported respiratory symptoms has been described after recreational and occupational exposures to Florida red-tide aerosols, particularly among individuals with asthma. Before and after 1 h spent on beaches with and without an active K brevis red-tide exposure, 97 persons >or= 12 years of age with physician-diagnosed asthma were evaluated by questionnaire and spirometry. Concomitant environmental monitoring, water and air sampling, and personal monitoring for brevetoxins were performed. Participants were significantly more likely to report respiratory symptoms after K brevis red-tide aerosol exposure than before exposure. Participants demonstrated small, but statistically significant, decreases in FEV(1), midexpiratory phase of forced expiratory flow, and peak expiratory flow after exposure, particularly among those participants regularly using asthma medications. No significant differences were detected when there was no Florida red tide (ie, during nonexposure periods). This study demonstrated objectively measurable adverse changes in lung function from exposure to aerosolized Florida red-tide toxins in asthmatic subjects, particularly among those requiring regular therapy with asthma medications. Future studies will assess these susceptible subpopulations in more depth, as well as the possible long-term effects of these toxins.

Little is known about the joint effects of maternal asthma and maternal depression on childhood asthma. To examine whether maternal depression and maternal asthma lead to greater risk of childhood asthma than maternal asthma alone. Cross-sectional studies of children (6-14 years old) in San Juan, Puerto Rico (n = 655) and Sweden (n = 6,887) were conducted. In Puerto Rico, maternal depressive symptoms were defined using the Center for Epidemiologic Studies Depression Scale (CES-D) questionnaire. In Sweden, maternal physician-diagnosed depression was derived from national registries, and maternal depressive symptoms were defined using an abbreviated CES-D questionnaire. Childhood asthma was defined as physician-diagnosed asthma plus current wheeze (in Puerto Rico) or plus medication use (in Sweden). Logistic regression was used for multivariable analysis. Compared with Puerto Rican children whose mothers had neither asthma nor depressive symptoms, those whose mothers had asthma but no depressive symptoms had 3.2 times increased odds of asthma (95% confidence interval [CI] = 2.1-4.8) and those whose mothers had asthma and depressive symptoms had 6.5 times increased odds of asthma (95% CI = 3.3-13.0). Similar results were obtained for maternal depression and maternal asthma in the Swedish cohort (odds ratio for maternal asthma without maternal depression = 2.8, 95% CI = 2.1-3.7; odds ratio for maternal asthma and maternal depression = 4.0, 95% CI = 1.7-9.6). Although the estimated effect of maternal asthma on childhood asthma was increased when maternal depressive symptoms (Puerto Rico) or maternal depression (Sweden) was present, there were no statistically significant additive interactions. Maternal depression can further increase the risk of asthma in children whose mothers have a history of asthma. Copyright © 2016 American College of Allergy, Asthma & Immunology.

To describe how the types of healthcare expenditures for patients with asthma have changed over the past decade. Cross-sectional comparison between individuals from 1996 to 1998 and 2004 to 2006. Expenditures among US individuals (aged 5 to 56 years) with asthma were compared using the 1996 to 1998 and the 2004 to 2006 Medical Expenditure Panel Surveys. Direct expenditures (medications, inpatient, outpatient, and emergency services) and changes in productivity (missed school and work days) were compared over this time frame. The adjusted analyses controlled for age, education level, race/ethnicity, gender, poverty, region, metropolitan statistical area, self-reported health, and Charlson Comorbidity Index. Mean annual per capita healthcare expenditures increased between 1996 to 1998 and 2004 to 2006 ($3802 vs $5322 inflated to 2010 US dollars, P <.0001). Annual medication expenditures doubled from $974 to $2010 per person (P <.0001) and outpatient visit expenditures increased from $861 to $1174 (P <.0001) while hospitalization and emergency department (ED) visit expenditures were similar over the same time period. Missed school and work days decreased between the 2 periods (9.23 days in 1996-1998 vs 6.39 days in 2004-2006, P = .001). An increase in total direct expenditures in individuals with asthma was largely driven by an increase in spending on medications comparing 2004 to 2006 and 1996 to 1998 data. However, this increase was not offset by lower spending on hospitalization and ED visits.

Insight Into the Relationship Between Gastroesophageal Reflux Disease and Asthma

PubMed Central

Vaezi, Michael F

2014-01-01

Gastroesophageal reflux disease (GERD) is a common condition that presents with symptoms of heartburn and regurgitation. Asthma is an equally common medical condition that often coexists with GERD. The clinical scenario of difficult-to-treat asthma in the setting of concomitant GERD leads to the possibility of GERD-induced asthma. However, asthma may also induce GERD, so confusion has developed about the role of GERD in patients with moderate to severe asthma. Acid-suppressive therapy may be initiated in patients with asthma, but controlled studies have recently questioned the role of such therapy and, thus, have caused further confusion in this field. Recent advancements in the field of esophageal physiologic testing in GERD have introduced the concept of impedance–pH monitoring, which suggests a possible role of nonacid reflux in those who continue to be symptomatic despite acid-suppressive therapy. However, recent data caution about the role of surgical fundoplication based solely on the results of impedance monitoring. This article reviews current knowledge in the fields of GERD and asthma and suggests a possible treatment option for this group of patients. PMID:28435409

To compare asthma care roles of maternal and paternal caregivers, and examine associations between caregiver involvement and the outcomes of adherence, morbidity, and parental quality of life (QoL). Mothers and fathers in 63 families of children, ages 5-9 years, with persistent asthma completed semistructured interviews and questionnaires. Adherence was measured via electronic monitoring. Paired t tests compared parental asthma care roles, and analysis of covariance, controlling for socioeconomic status, evaluated associations of asthma outcomes with caregiver involvement scores. Mothers had higher scores on measures of involvement, beliefs in medication necessity, and on four subscales of the Family Asthma Management System Scale interview (Asthma Knowledge, Relationship with Provider, Symptom Assessment, and Response to Symptoms). Maternal QoL was lowest when both maternal and paternal involvement was high. Paternal involvement was associated with increased morbidity. There is room for enhancement of fathers' asthma care roles. Higher levels of paternal involvement may be driven by family need. © The Author 2015.

To estimate the cost of diagnosis and treatment of asthma. We used the perspective of society. We sequentially included for 12 months, in 2011-2012, 117 individuals over five years of age who were treated for asthma in the Pneumology and Allergy-Immunology Services of the Piquet Carneiro Polyclinic, Universidade do Estado do Rio de Janeiro. All of them were interviewed twice with a six-month interval for data collection, covering 12 months. The cost units were identified and valued according to defined methods. We carried out a sensitivity analysis and applied statistical methods with a significance level of 5% for cost comparisons between subgroups. The study consisted of 108 patients, and 73.8% of them were women. Median age was 49.5 years. Rhinitis was present in 83.3% of the individuals, and more than half were overweight or obese. Mean family income was U$915.90/month (SD = 879.12). Most workers and students had absenteeism related to asthma. Total annual mean cost was U$1,291.20/patient (SD = 1,298.57). The cost related to isolated asthma was U$1,155.43/patient-year (SD = 1,305.58). Obese, severe, and uncontrolled asthmatic patients had higher costs than non-obese, non-severe, and controlled asthmatics, respectively. Severity and control level were independently associated with higher cost (p = 0.001 and 0.000, respectively). The direct cost accounted for 82.3% of the estimated total cost. The cost of medications for asthma accounted for 62.2% of the direct costs of asthma. Asthma medications, environmental control measures, and long-term health leaves had the greatest potential impact on total cost variation. The results are an estimate of the cost of treating asthma at a secondary level in the Brazilian Unified Health System, assuming that the treatment used represents the ideal approach to the disease.

2012-01-01

Introduction Bronchial Asthma is one of the most extensively studied respiratory diseases and its genetic basis is well established. Dermatoglyphic traits are formed under genetic control early in development but may be affected by environmental factors during first trimester of pregnancy. These patterns may represent the genetic makeup of an individual and therefore his/her predisposition to certain diseases. Patterns of dermatoglyphics have been studied in various congenital disorders like Down’s syndrome, Klinefelter’s syndrome and also in chronic diseases like Hypertension, Diabetes Mellitus etc. Epidermal ridge patterns of finger tips in bronchial asthma patients were studied to find out fingertip pattern as Dermatoglyphic features in patients of Bronchial Asthma; it’s comparison and association if exists between normal and bronchial asthma patients and also to find use of fingertip pattern in early childhood as non-invasive anatomical marker for bronchial asthma in adulthood. Methods The study was conducted on clinically diagnosed all bronchial asthma patients attending OPD of Dr Ulhas Patil Medical College, Jalgaon. Matched controls were selected without any respiratory problem or any symptoms related to asthma from medical students, staff members and paramedical staff of hospital after taking the informed consent and permission from the institutional ethical committee. Data collection and fingertip prints were taken by ink and rolling finger method. Prints taken were analysed and tabulated; data was analysed by using statistical tests. Results Study shows that decrease in number of arches, increase in AFRC in patients as compared with controls. Also there were increased ulnar loops in male patients and increased Whorls and radial loops in female patients. Conclusion The fingerprints can represent a non-invasive anatomical marker of bronchial asthma risk and facilitate early detection and effective management which is vital for selecting appropriate agents for treating infections.

Asthma is associated with a substantial economic burden on the German Statutory Health Insurance. To determine costs and resource utilization associated with asthma and to analyze the impact of disease severity on subgroups based on age and gender. A claims database analysis from the statutory health insurance perspective was conducted. Patients with an ICD-10-GM code of asthma were extracted from a 10% sample of a large German sickness fund. Five controls for each asthma patient matched by age and gender were randomly selected from the same database. Costs and resource utilization were calculated for each individual in the asthma and control group. Incremental asthma-related costs were calculated as the mean cost difference. Based on prescribed asthma medication, patients were classified as intermittent or persistent. In addition, age groups of ≤ 5, 6-18, and >18 years were analyzed separately and gender differences were investigated. Overall, 49,668 individuals were included in the asthma group. On average, total annual costs per patient were €753 higher (p = 0.000) compared to the control group (€2,168 vs. €1,415). Asthma patients had significantly higher (p = 0.000) outpatient (€217), inpatient (€176), and pharmacy costs (€259). Incremental asthma-related total costs were higher for patients with persistent asthma compared to patients with intermittent asthma (€1,091 vs. €408). Women aged >18 years with persistent asthma had the highest difference in costs compared to their controls (€1,207; p < 0.0001). Corresponding healthcare resource utilization was significantly higher in the asthma group (p = 0.000). The treatment of asthma is associated with an increased level of healthcare resource utilization and significantly higher healthcare costs. Asthma imposes a substantial economic burden on sickness funds.

To explore reasons for increased risk of hospital admission among south Asian patients with asthma. Qualitative interview study using modified critical incident technique and framework analysis. Newham, east London, a deprived area with a large mixed south Asian population. 58 south Asian and white adults with asthma (49 admitted to hospital with asthma, 9 not admitted); 17 general practitioners; 5 accident and emergency doctors; 2 out of hours general practitioners; 1 asthma specialist nurse. Patients' and health professionals' views on influences on admission, events leading to admission, general practices' organisation and asthma strategies, doctor-patient relationship, and cultural attitudes to asthma. South Asian and white patients admitted to hospital coped differently with asthma. South Asians described less confidence in controlling their asthma, were unfamiliar with the concept of preventive medication, and often expressed less confidence in their general practitioner. South Asians managed asthma exacerbations with family advocacy, without systematic changes in prophylaxis, and without systemic corticosteroids. Patients describing difficulty accessing primary care during asthma exacerbations were registered with practices with weak strategies for asthma care and were often south Asian. Patients with easy access described care suggesting partnerships with their general practitioner, had better confidence to control asthma, and were registered with practices with well developed asthma strategies that included policies for avoiding hospital admission. The different ways of coping with asthma exacerbations and accessing care may partly explain the increased risk of hospital admission in south Asian patients. Interventions that increase confidence to control asthma, confidence in the general practitioner, understanding of preventive treatment, and use of systemic corticosteroids in exacerbations may reduce hospital admissions. Development of more sophisticated asthma strategies by practices with better access and partnerships with patients may also achieve this.

Asthma often begins in childhood or early adulthood and is a common disease among conscripts. The identification of long-term predictive factors for persistent asthma may lead to improved treatment opportunities and better disease control. Our aim was to study the prognostic factors of the severity of asthma among 40-year-old male conscripts whose asthma began in youth. We studied 119 conscripts who were referred to the Central Military Hospital during 1987-1990 due to asthma and who attended a follow-up visit approximately 20 years later. Asthma severity was evaluated during military service according to the medical records, and 20 years later during a follow-up visit using Global Initiative for Asthma guidelines. We used the results of lung function and allergy tests at baseline as predictors of current persistent asthma. Compared with baseline, asthma was less severe at follow-up: 11.8% of subjects were in remission, 42.0% had intermittent asthma, 10.9% had mild persistent asthma, and 35.3% had moderate/severe persistent asthma (p < .001). In multivariate models, a positive exercise test at baseline yielded an odds ratio (OR) of 3.2 (95% CI 1.0-9.8, p = .046), a decreased FEV1/FVC % predicted an OR of 4.0 (95% CI 1.7-9.3, p = .002), and a decreased FEF50% % predicted an OR of 2.8 (95% CI 1.3-6.4, p = .012) for current persistent asthma. About half of the men had persistent asthma at the 20-year follow-up. Positive exercise tests and obstructive spirometry results were related to the persistence of asthma and may be useful long-term prognostic factors for asthma severity.

The aim of this study was to explore the asthma management experiences of people with asthma within the Arabic-speaking community in Australia. Semi-structured interviews guided by a schedule of questions were conducted with 25 Arabic-speaking women with asthma\\carer of a child with asthma, recruited from medical practices and community centers in Melbourne, Australia. Twenty-five Arabic-speaking participants with asthma or caring for those with asthma were interviewed. Interviews lasted on average 25 minutes. Most participants or those they were caring for did not have well-controlled asthma. Thematic analyses of the interview transcripts highlighted five key emergent themes: stigma, health literacy, non-adherence, expectations, and coping styles. Findings indicated that many participants were not conversant about local information avenues or healthcare or facilities such as the Asthma Foundation or availability of Arabic translators during general practitioner (GP) consults. Many recent migrants were generally non-adherent with treatment; preferring to follow traditional folk medicine rather than consulting a GP or pharmacist. Some unrealistic expectations from doctors/treatment goals were expressed by a few participants. Some parents of children with asthma reported disappointment with the fact that their children did not grow out of asthma. Low health literacy and in particular knowledge about asthma, cultural beliefs, language, and migration-related issues may all be affecting the level of asthma control in the Arabic-speaking population in Australia. Measures to enhance asthma and health system literacy designed to be culturally concordant with the beliefs, expectations, and experiences of such populations may be key to improving asthma management.

The purpose of this randomized control trial was to evaluate the effects of a computer-assisted instructional (CAI) game on asthma symptoms (eg, coughing, wheezing, shortness of breath, and nighttime awakenings) in 7- to 12-year-old inner-city children over 12 weeks. A CAI that focused on reducing environmental irritants/allergens and the correct use of prescribed medications to prevent asthma symptoms was used with 101 children (56 in the intervention group and 45 in the control group). The primary outcome evaluated a change in children's asthma symptoms as measured by responses to nine symptom questions in Juniper's Pediatric Asthma Quality of Life Questionnaire (PAQOL) and measurements of lung function. No significant changes in asthma symptoms occurred between the two groups before and after the intervention. No significant changes were noted in PAQOL scores for activities, emotions, and total PAQOL score, lung function measurements, and asthma severity between the two groups. Asthma knowledge of both groups was high before intervention, but there were no significant changes between groups after the intervention. Findings indicate that this CAI game was not effective in improving asthma symptoms in this group of children.

COSTS OF CHILDHOOD ASTHMA DUE TO TRAFFIC-RELATED POLLUTION IN TWO CALIFORNIA COMMUNITIES

Recent research suggests the burden of childhood asthma attributable to air pollution has been underestimated in traditional risk assessments, and there are no estimates of these associated costs. We estimated the yearly childhood asthma-related costs attributable to air pollution for Riverside and Long Beach, California, including: 1) the indirect and direct costs of health care utilization due to asthma exacerbations linked to traffic-related pollution (TRP); and 2) the costs of health care for asthma cases attributable to local TRP exposure. We estimated these costs using estimates from peer-reviewed literature and the authors' analysis of surveys (Medical Expenditure Panel Survey, California Health Interview Survey, National Household Travel Survey, and Health Care Utilization Project). A lower-bound estimate of the asthma burden attributable to air pollution was $18 million yearly. Asthma cases attributable to TRP exposure accounted for almost half of this cost. The cost of bronchitic episodes was a major proportion of both the annual cost of asthma cases attributable to TRP and of pollution-linked exacerbations. Traditional risk assessment methods underestimate both the burden of disease and cost of asthma associated with air pollution, and these costs are borne disproportionately by communities with higher than average TRP.

This study tested the ability of an electronic prompt to promote an asthma assessment during primary care visits. We performed a prospective study of all eligible adult patients with previously diagnosed asthma in three geographically distinct ambulatory family medicine clinics within a 4-month period. The usual clinic visit process was performed at two geographically distinct control sites (n = 75 and n = 55 patients, respectively). The intervention group site (n = 64) had an electronic flag embedded in the Patient Check-in Locator field which prompted the distribution of a self-administered Asthma Management Questionnaire (AMQ) in the waiting room. The primary outcome measure was a documented asthma severity assessment. The front desk distributed the AMQ successfully in 100% of possible opportunities and the AMQ was completed by 84% of patients. Providers in the intervention group were significantly more likely than providers in the two non-intervention groups to document asthma severity in the medical record during a non-asthma ambulatory clinic visit (63.3% vs. 18.7% vs. 3.6%; p < .001). The provision of standardized asthma information triggered by an electronic prompt at the time of check-in effectively initiates an asthma assessment during the primary care visits.

To evaluate limited English proficiency (LEP) Latino caregiver asthma knowledge after exposure to an educational video designed for this target group. A cross-sectional, interventional study was performed. We aimed to evaluate the post-test impact on asthma knowledge from baseline after exposure to a patient-centered, evidence-based, and professionally produced Spanish asthma educational video. Participants included LEP Latino caregivers of children 2-12 years old with persistent asthma. Enrollment was performed during ED encounters or scheduled through a local community organization. Asthma knowledge was measured with a validated Spanish parental asthma knowledge questionnaire. Differences in mean scores were calculated with a paired t-test. Twenty caregivers were enrolled. Participants included mothers (100%) from Puerto Rico (75%), with a high-school diploma or higher (85%), with no written asthma action plan (65%), whose child's asthma diagnosis was present for at least 3 years (80%). Mean baseline asthma knowledge scores improved 8 points from 58.4 to 66.4 after watching the educational video (95% CI 5.3-10.7; t(19) = 6.21, p < 0.01). Knowledge improvements were similar across the ED and community groups. Knowledge gains were observed in the areas of ED utilization, medication usage, and activity limitations. The developed educational video improved caregiver asthma knowledge for a Latino population facing communication barriers to quality asthma care. Dissemination of this educational resource to LEP caregivers has the potential to improve pediatric asthma care in the United States.

Previous research has shown that people with disabilities have higher rates of some chronic diseases and receive poorer disease-specific care than their counterparts without disabilities. Yet, little is known about the relationship between asthma and disability. This study examines whether differences in the prevalence of asthma, asthma flare, and asthma-related measures of health care quality, utilization and cost exist among people with physical limitations (PL) and without any limitations. Data from the 2004-2010 Medical Expenditure Panel Survey were pooled to compare outcomes for working-age adults (18-64) with PL to those with no limitations. People with PL had higher rates of asthma (13.8% vs. 5.9%, p < 0.001) and recent asthma flare (52.6% vs. 39.6%, p < 0.001) than people without limitations. There were no differences in health care quality, utilization or cost between people with PL and people without limitations in multivariate analyses. Although there are no differences in asthma-related quality or utilization of health care, people with PL have poorer asthma control than people without limitations. Research is needed to determine what factors (e.g., focus on other acute ailments, perceptions that asthma control cannot improve) are related to this outcome. Future research must also examine differences in asthma severity, and its impact on asthma control and health care-related outcomes, among people with and without disabilities.

Sánchez, Trinidad; Castro-Rodríguez, José A; Brockmann, Pablo E

2016-01-01

The objective was to perform a systematic review in order to describe the relationship between asthma and sleep-disordered breathing (SDB) in children, especially regarding the impact of treatment and management. We performed an electronic search in MEDLINE, EMBASE, and LILACS database. Study inclusion criteria were the following: 1) studies that examined the relationship between asthma/wheezing and SDB/obstructive sleep apnea (OSA); and 2) studies conducted in children <18 years of age. Primary outcomes were the prevalence of asthma and SDB, the tests used for diagnosis, and the influence of their treatment and management. One thousand and twenty studies were identified, among which 32 were selected (n=143,343 children; 51% males; age [mean ± standard deviation] 8.4±2.5 years). Most studies (n=26) diagnosed SDB using questionnaires or clinical history. Nine studies performed a sleep study for diagnosing OSA. The diagnosis of asthma was based on clinical history (n=16), previous medical diagnosis (n=4), questionnaires (n=12), and spirometry (n=5). Children with asthma were more likely to develop habitual snoring and OSA, and children with SDB were more likely to develop asthma. Moreover, asthma was associated with more severe OSA, and the presence of SDB was associated with severe asthma. Treatment of SDB with adenotonsillectomy was associated with significant asthma improvement. The relationship between asthma and SDB appears to be bidirectional, and adenotonsillectomy appears to improve asthma control. Future trials on how asthma treatment could impact on SDB are needed.

In a sample of adults with asthma receiving care and medication in an outpatient pulmonary clinic, this study tested for statistical associations between social problem-solving styles, asthma control, and asthma-related quality of life. These variables were measured cross sectionally as a first step toward more systematic application of social problem-solving frameworks in asthma self-management training. Recruitment occurred during pulmonology clinic service hours. Forty-four adults with physician-confirmed diagnosis of asthma provided data including age, gender, height, weight, race, income, and comorbid conditions. The Asthma Control Questionnaire, the Mini Asthma Quality of Life Questionnaire (Short Form), and peak expiratory force measures offered multiple views of asthma health at the time of the study. Maladaptive coping (impulsive and careless problem-solving styles) based on transactional stress models of health were assessed with the Social Problem-Solving Inventory-Revised: Short Form. Controlling for variance associated with gender, age, and income, individuals reporting higher impulsive-careless scores exhibited significantly lower scores on asthma control (β = 0.70, p = 0.001, confidence interval (CI) [0.37-1.04]) and lower asthma-related quality of life (β = 0.79, p = 0.017, CI [0.15-1.42]). These findings suggest that specific maladaptive problem-solving styles may uniquely contribute to asthma health burdens. Because problem-solving coping strategies are both measureable and teachable, behavioral interventions aimed at facilitating adaptive coping and problem solving could positively affect patient's asthma management and quality of life.

Background Whether Web-based technologies can improve disease self-management is uncertain. My Asthma Portal (MAP) is a Web-based self-management support system that couples evidence-based behavioral change components (self-monitoring of symptoms, physical activity, and medication adherence) with real-time monitoring, feedback, and support from a nurse case manager. Objective The aim of this study was to compare the impact of access to a Web-based asthma self-management patient portal linked to a case-management system (MAP) over 6 months compared with usual care on asthma control and quality of life. Methods A multicenter, parallel, 2-arm, pilot, randomized controlled trial was conducted with 100 adults with confirmed diagnosis of asthma from 2 specialty clinics. Asthma control was measured using an algorithm based on overuse of fast-acting bronchodilators and emergency department visits, and asthma-related quality of life was assessed using the Mini-Asthma Quality of Life Questionnaire (MAQLQ). Secondary mediating outcomes included asthma symptoms, depressive symptoms, self-efficacy, and beliefs about medication. Process evaluations were also included. Results A total of 49 individuals were randomized to MAP and 51 to usual care. Compared with usual care, participants in the intervention group reported significantly higher asthma quality of life (mean change 0.61, 95% CI 0.03 to 1.19), and the change in asthma quality of life for the intervention group between baseline and 3 months (mean change 0.66, 95% CI 0.35 to 0.98) was not seen in the control group. No significant differences in asthma quality of life were found between the intervention and control groups at 6 (mean change 0.46, 95% CI –0.12 to 1.05) and 9 months (mean change 0.39, 95% CI –0.2 to 0.98). For poor control status, there was no significant effect of group, time, or group by time. For all self-reported measures, the intervention group had a significantly higher proportion of individuals, demonstrating a minimal clinically meaningful improvement compared with the usual care group. Conclusions This study supported the use of MAP to enhance asthma quality of life but not asthma control as measured by an administrative database. Implementation of MAP beyond 6 months with tailored protocols for monitoring symptoms and health behaviors as individuals’ knowledge and self-management skills improve may result in long-term gains in asthma control.

A systematic review of explanatory factors of barriers and facilitators to improving asthma management in South Asian children

PubMed Central

2014-01-01

Background South Asian children with asthma are less likely to receive prescriptions and more likely to suffer uncontrolled symptoms and acute asthma admissions compared with White British children. Understanding barriers are therefore vital in addressing health inequalities. We undertook a systematic review identifying explanatory factors for barriers and facilitators to asthma management in South Asian children. South Asians were defined as individuals of Indian, Pakistani or Bangladeshi descent. Methods Data Sources - Medline, HMIC, EMBASE, ASSIA, Web of Science, BNI, CINAHL, PsycINFO, OpenSIGLE, CRD, Scopus, NHS Evidence, Cochrane Library, Campbell Collaboration, RCPCH, ATS, ERS, Asthma UK, Google Scholar & Asthma Guidelines (BTS, GINA, ATS, Monash, NAEPP, Singapore & New Zealand) to August 2013. Inclusion Criteria – Qualitative, quantitative or mixed methods research with primary focus on identifying explanations for barriers and/or facilitators to asthma management in South Asian children aged 0–18 years with diagnosed/suspected asthma and/or carers and/or healthcare professionals. Data Extraction – Three authors independently reviewed, selected & extracted eligible articles with disagreements resolved by research team discussion. Results 15 studies encompassing 25,755 children, 18,483 parents/carers and 239 healthcare professionals were included. Barriers and explanatory factors identified were: 1. Lack of asthma knowledge in families and healthcare professionals. 2. Under-use of preventer medications. 3. Non-acceptance/denial of asthma. 4. Over-reliance on Emergency Department management. 5. Communication problems. 6. Non-adherence to medication. 7. Use of complementary therapies. Little facilitators regarding asthma management were identified. Conclusions Several key issues were identified as likely to be ethnic-specific to South Asian families, rather than a reflection of minority status: impact of parental and professional knowledge and beliefs, health service utilisation pattern explanations and the impact of prejudice and stigmatisation. Other explanations such as language barriers are not strictly ethnic specific but instead reflect a minority position. Further research is required to identify why barriers exist, the mechanisms by which they impact on asthma management and how they can be overcome. Furthermore, understanding the difference between barriers and explanations that are ethnic-specific and those that are related to being a minority will enable the application of generic system-wide interventions where ethnicity is not the issue and ethnically-tailored interventions where needed.

Introduction. Parental perceptions and practices are important for improving the asthma outcomes in children; indeed, evidence shows that parents of asthmatic children harbor considerable misperceptions of the disease. Objective. To investigate the perceptions and practices of parents toward asthma and its management in Saudi children. Methods. Using a self-administered questionnaire, a two-stage cross-sectional survey of parents of children aged between 3 and 15 years, was conducted from schools located in Riyadh province in central Saudi Arabia. Results. During the study interval, 2000 parents were asked to participate in the study; 1450 parents responded, of whom 600 (41.4%) reported that their children had asthma, dyspnea, or chest allergy (recurrent wheezing or coughing), while 478 (32.9%) of the parents reported that their children were diagnosed earlier with asthma by a physician. Therefore, the final statistical analyses were performed with 600 participants. Furthermore, 321 (53.5%) respondents believed that asthma is solely a hereditary disease. Interestingly, 361 (60.3%) were concerned about side effects of inhaled corticosteroids and 192 (32%) about the development of dependency on asthma medications. Almost 76% of parents had previously visited a pediatric emergency department during an asthma attack. Conclusions. Parents had misperceptions regarding asthma and exhibited ineffective practices in its management. Therefore, improving asthma care and compliance requires added parental education. PMID:27843948

OBJECTIVE: To identify risk factors for death among patients with severe asthma. METHODS: This was a nested case-control study. Among the patients with severe asthma treated between December of 2002 and December of 2010 at the Central Referral Outpatient Clinic of the Bahia State Asthma Control Program, in the city of Salvador, Brazil, we selected all those who died, as well as selecting other patients with severe asthma to be used as controls (at a ratio of 1:4). Data were collected from the medical charts of the patients, home visit reports, and death certificates. RESULTS: We selected 58 cases of deaths and 232 control cases. Most of the deaths were attributed to respiratory causes and occurred within a health care facility. Advanced age, unemployment, rhinitis, symptoms of gastroesophageal reflux disease, long-standing asthma, and persistent airflow obstruction were common features in both groups. Multivariate analysis showed that male gender, FEV1 pre-bronchodilator < 60% of predicted, and the lack of control of asthma symptoms were significantly and independently associated with mortality in this sample of patients with severe asthma. CONCLUSIONS: In this cohort of outpatients with severe asthma, the deaths occurred predominantly due to respiratory causes and within a health care facility. Lack of asthma control and male gender were risk factors for mortality. PMID:25210958

Is asthma associated with cognitive impairments? A meta-analytic review.

Irani, Farzin; Barbone, Jordan Mark; Beausoleil, Janet; Gerald, Lynn

Asthma is a chronic disease with significant health burden and socioeconomic and racial/ethnic disparities related to diagnosis and treatment. Asthma primarily affects the lungs, but can impact brain function through direct and indirect mechanisms. Some studies have suggested that asthma negatively impacts cognition, while others have failed to identify asthma-related cognitive compromise. We aimed to conduct a meta-analysis of cognition in individuals with asthma compared to that in healthy controls. We also examined the impact of some key potential moderators. Data on cognitive outcome measures and sociodemographic, illness-related, and study-related variables were extracted from studies reporting cognitive test performance in individuals with asthma compared to that in controls. There was no evidence of publication bias. A random-effects model examining differences in task performance between 2017 individuals with asthma and 2131 healthy controls showed significant effects in the small to medium range. Cognitive deficits associated with asthma were global, with strongest effects on broader measures involving academic achievement and executive functioning, but with additional impact on processing speed, global intellect, attention, visuospatial functioning, language, learning, and memory. Severity of asthma was a key moderator, with greatest cognitive deficits associated with severe asthma. Cognitive burden was also greatest in asthma patients who were younger, males, from low socioeconomic backgrounds, and from racial/ethnic minorities. Effects were independent of type of population (child versus adult), type of study (norm-referenced versus control-referenced), or reported use of oral or inhaled corticosteroid medications. There is cognitive burden associated with asthma, particularly among vulnerable groups with severe asthma. This could be due to increased risk of intermittent cerebral hypoxia in severe asthma. The clinical need to assess cognition in individuals with asthma is underscored.

Asthma is one of the most common allergic respiratory diseases around the world and places great burden on medical payment. Chinese herbal medicine (CHM) is commonly used for Taiwanese children to control diseases. The aim of this study is to analyze the CHM prescriptions for asthmatic children by using a nationwide clinical database. The National Health Insurance Research Database (NHIRD) was used to perform this study. Medical records from 1997 to 2009 with diagnosis with asthma made for children aged 6 to 18 were included into the analysis. Association rule mining and social network analysis were used to analyze the prevalence of single CHM and its combinations. Ma-Xing-Gan-Shi-Tang (MXGST) was the most commonly used herbal formula (HF) (20.2% of all prescriptions), followed by Xiao-Qing-Long-Tang (13.1%) and Xing-Su-San (12.8%). Zhe Bei Mu is the most frequently used single herb (SH) (14.6%), followed by Xing Ren (10.7%). MXGST was commonly used with Zhe Bei Mu (3.5%) and other single herbs capable of dispelling phlegm. Besides, MXGST was the core formula to relieve asthma. Further studies about efficacy and drug safety are needed for the CHM commonly used for asthma based on the result of this study.

To examine the effect of ambulatory health care processes on asthma hospitalizations. A retrospective cohort study using electronic health records was completed. Patients aged 2-18 years receiving health care from 1 of 5 urban practices between Jan 1, 2004 and Dec 31, 2008 with asthma documented on their problem list were included. Independent variables were modifiable health care processes in the primary care setting: (1) use of asthma controller medications; (2) regular assessment of asthma symptoms; (3) use of spirometry; (4) provision of individualized asthma care plans; (5) timely influenza vaccination; (6) access to primary healthcare; and (7) use of pay for performance physician incentives. Occurrence of one or more asthma hospitalizations was the primary outcome of interest. We used a log linear model (Poisson regression) to model the association between the factors of interest and number of asthma hospitalizations. 5,712 children with asthma were available for analysis. 96% of the children were African American. The overall hospitalization rate was 64 per 1,000 children per year. None of the commonly used asthma-specific indicators of high quality care were associated with fewer asthma hospitalizations. Children with documented asthma who experienced a lack of primary health care (no more than one outpatient visit at their primary care location in the 2 years preceding hospitalization) were at higher risk of hospitalization compared to those children with a greater number of visits (incidence rate ratio 1.39; 95% CI 1.09-1.78). In children with asthma, more frequent primary care visits are associated with reduced asthma hospitalizations.

Data from Washington State's work-related asthma surveillance system were used to characterize isocyanate-induced asthma cases occurring from 1999 through 2010. Injured worker interviews and medical records were used to describe the industry, job title, work process, workers’ compensation cost, and exposure trends associated with 27 cases of isocyanate-induced asthma. The majority (81%) of cases were classified within the surveillance system as new-onset asthma while 19% were classified as work-aggravated asthma. The workers’ compensation cost for isocyanate-induced asthma cases was $1.7 million; this was 14% of the total claims cost for all claims in the asthma surveillance system. The majority of cases (48%) occurred from paint processes, followed by foam application or foam manufacturing (22%). Nine of the asthma cases associated with spray application occurred during application to large or awkward-shaped objects. Six workers who did not directly handle isocyanates (indirect exposure) developed new-onset asthma. Two cases suggest that skin contact and processes secondary to the isocyanate spray application, such as cleanup, contributed to immune sensitization. Surveillance data provide insight for the prevention of isocyanate-induced respiratory disease. Key observations are made regarding the development of work-related asthma in association with a) paint application on large objects difficult to ventilate, b) indirect exposure to isocyanates, c) exposure during secondary or cleanup processes, and d) reports of dermal exposure.

BACKGROUND: In 2010, the Canadian Thoracic Society (CTS) published a Consensus Summary for the diagnosis and management of asthma in children six years of age and older, and adults, including an updated Asthma Management Continuum. The CTS Asthma Clinical Assembly subsequently began a formal clinical practice guideline update process, focusing, in this first iteration, on topics of controversy and/or gaps in the previous guidelines. METHODS: Four clinical questions were identified as a focus for the updated guideline: the role of noninvasive measurements of airway inflammation for the adjustment of anti-inflammatory therapy; the initiation of adjunct therapy to inhaled corticosteroids (ICS) for uncontrolled asthma; the role of a single inhaler of an ICS/long-acting beta2-agonist combination as a reliever, and as a reliever and a controller; and the escalation of controller medication for acute loss of asthma control as part of a self-management action plan. The expert panel followed an adaptation process to identify and appraise existing guidelines on the specified topics. In addition, literature searches were performed to identify relevant systematic reviews and randomized controlled trials. The panel formally assessed and graded the evidence, and made 34 recommendations. RESULTS: The updated guideline recommendations outline a role for inclusion of assessment of sputum eosinophils, in addition to standard measures of asthma control, to guide adjustment of controller therapy in adults with moderate to severe asthma. Appraisal of the evidence regarding which adjunct controller therapy to add to ICS and at what ICS dose to begin adjunct therapy in children and adults with poor asthma control supported the 2010 CTS Consensus Summary recommendations. New recommendations for the adjustment of controller medication within written action plans are provided. Finally, priority areas for future research were identified. CONCLUSIONS: The present clinical practice guideline is the first update of the CTS Asthma Guidelines following the Canadian Respiratory Guidelines Committee’s new guideline development process. Tools and strategies to support guideline implementation will be developed and the CTS will continue to regularly provide updates reflecting new evidence. PMID:22536582

Objective: To evaluate the changes of asthma control, disease management and perception in recent years in China. Methods: We conducted 2 multi-center, cross-sectional surveys. Outpatient asthmatic patients from 10 cities in mainland China (2007-2008) and 30 central cities from 30 provinces in China (except Tibet)(2015-2016) were recruited respectively. Data of asthma control, disease management and perception from the 2 surveys were compared for 10 cities which took part in both of the 2 surveys. Chi-square test was used for comparison between groups. Results: The asthma control level improved from 28.7%(839/2 928) in 2007-2008 to 39.2%(533/1 361) in 2015-2016( P <0.01). The rate of emergency visits was 18.2%(248/1 362) in 2015-2016, which was lower than that in 2007-2008(33.9%, 1 032/3 044)( P <0.01). The rate of peak flow meter (PFM) usage was 17.9%(244/1 360) in 2015-2016, which was slightly lower than the PFM usage rate in 2007-2008(21.8%, 660/3 030)( P =0.004). 56.0%(763/1 362) of the patients used inhaled corticosteroid (ICS) + formoterol to control asthma when asthma symptoms deteriorated in 2015-2016, which was higher than the result of 2007-2008(31.8%, 803/2 524)( P <0.01). 71.1%(968/1 361) of the patients in 2015-2016 had a right perception on disease nature, while the result in 2007-2008 was 63.3%(1 889/2 986)( P <0.01). 61.6%(839/1 362) of the patients in 2015-2016 had a right perception on medication choice on daily-use first-line medication for chronic asthma, while the result in 2007-2008 was 51.0%(1 500/2 942)( P <0.01). Conclusion: The current level of asthma control and disease perception in China improved significantly in recent years, while the rate of PFM usage showed no significant improvement. Asthma action plan including PFM monitoring and asthma self-management should be further promoted nationwide.
