Antiretroviral (ARV) medication diversion to the illicit market has been documented in South Florida, and linked to sub-optimal adherence in people living with HIV. ARV diversion reflects an unmet need for care in vulnerable populations that have difficulty engaging in consistent HIV care due to competing needs and co-morbidities. This study applies the Gelberg-Andersen behavioral model of health care utilization for vulnerable populations to understand how social vulnerability is linked to ARV diversion and adherence. Cross-sectional data were collected from a targeted sample of vulnerable people living with HIV in South Florida between 2010 and 2012 (n = 503). Structured interviews collected quantitative data on ARV diversion, access and utilization of care, and ARV adherence. Logistic regression was used to estimate the goodness-of-fit of additive models that test domain fit. Linear regression was used to estimate the effects of social vulnerability and ARV diversion on ARV adherence. The best fitting model to predict ARV diversion identifies having a low monthly income and unstable HIV care as salient enabling factors that promote ARV diversion. Importantly, health care need factors did not protect against ARV diversion, evidence that immediate competing needs are prioritized even in the face of poor health for this sample. We also find that ARV diversion provides a link between social vulnerability and sub-optimal ARV adherence, with ARV diversion and domains from the Behavioral Model explaining 25 % of the variation in ARV adherence. Our analyses reveal great need to improve engagement in HIV care for vulnerable populations by strengthening enabling factors (e.g. patient-provider relationship) to improve retention in HIV care and ARV adherence for vulnerable populations.

We hypothesize that depression in type 2 diabetes might be associated with poor glycemic control, in part due to suboptimal self-care. We tested this hypothesis by examining the associations of depression with clinical and laboratory findings in a multicenter survey of Chinese type 2 diabetic patients. 2538 patients aged 18-75 years attending hospital-based clinics in four cities in China underwent detailed clinical-psychological-behavioral assessment during a 12-month period between 2011 and 2012. Depression was diagnosed if Patient Health Questionnaire-9 (PHQ-9) score ≥10. Diabetes self-care and medication adherence were assessed using the Summary of Diabetes Self-care Activities and the 4-item Morisky medication adherence scale respectively. In this cross-sectional study (mean age: 56.4 ± 10.5[SD] years, 53% men), 6.1% (n = 155) had depression. After controlling for study sites, patients with depression had higher HbA(1c) (7.9 ± 2.0 vs. 7.7 ± 2.0%, P = 0.008) and were less likely to achieve HbA(1c) goal of <7.0% (36.2% vs 45.6%, P = 0.004) than those without depression. They were more likely to report hypoglycemia and to have fewer days of being adherent to their recommended diet, exercise, foot care and medication. In logistic regression, apart from young age, poor education, long disease duration, tobacco use, high body mass index, use of insulin, depression was independently associated with failure to attain HbA(1c) target (Odds Ratio [OR] = 1.56, 95%CI:1.05-2.32, P = 0.028). The association between depression and glycemic control became non-significant after inclusion of adherence to diet, exercise and medication (OR = 1.48, 95% CI 0.99-2.21, P = 0.058). Depression in type 2 diabetes was closely associated with hyperglycemia and hypoglycemia, which might be partly mediated through poor treatment adherence. © 2014 Ruijin Hospital, Shanghai Jiaotong University School of Medicine and Wiley Publishing Asia Pty Ltd.

Background Type D personality is a known predictor of non-adherence to prescribed medication regimens among patients with heart failure (HF). Both Type D personality and non-adherence are independent predictors of poor health outcomes among HF patients. Self-efficacy, which is modifiable, is also associated with medication adherence. Objectives To determine the relationships among Type D personality, medication self-efficacy, and medication adherence in 84 patients with HF. Methods Medication self-efficacy, Type D personality, medication adherence, demographic and clinical data were collected. Hierarchical linear regression and mediation analyses were used. Results Type D patients were more likely to have lower medication self-efficacy (p = .023) and poorer medication adherence (p = .027) compared with non-Type D patients. Low medication self-efficacy was associated with poor medication adherence (p < .001). Type D did not predict (p = .422) medication adherence after entering medication self-efficacy in the model demonstrating that medication self-efficacy was a mediator of the relationship between Type D and medication adherence. Conclusions Medication self-efficacy mediates the relationship between Type D personality and medication adherence. Developing and applying interventions to enhance medication self-efficacy for Type D patients may help to sever the link between Type D personality and poor outcomes. PMID:25979573

Acceptance-based behavior therapy to promote HIV medication adherence.

A significant number of adults with HIV in the USA do not maintain adherence to highly active antiretroviral therapy (HAART) at adequate levels. Although traditional cognitive behavioral interventions have shown promise in promoting HAART adherence, acceptance-based behavior therapy (ABBT) may be particularly useful in this population. ABBT has the potential to overcome common avoidance-based barriers associated with poor adherence, including denial of various illness-related factors and avoidance of stigmatization. We describe the rationale for promoting psychological and behavioral acceptance in HIV-positive populations; outline an ABBT to promote HAART adherence targeting primary care patients from urban, minority, low socioeconomic backgrounds; and report preliminary qualitative observations of treatment feasibility and acceptability.

Background Bipolar disorder (BD) is a chronic mental illness associated with reduced quality of life, high rates of suicide, and high financial costs. Evidence indicates that psychosocial stress might play an important role in the onset and course of BD. Objective The objective of this study was to address the gap between coping theory and the clinical use of coping strategies used to self-manage BD. Methods In-depth interviews were conducted with a sample of 21 poorly adherent patients with BD. All interviews were audiotaped, transcribed verbatim, and analyzed using content analysis with an emphasis on dominant themes. Results Transcript-based analysis generated two major domains of coping strategies used to self-manage BD: 1) problem focused (altering eating habits, managing mood-stabilizing medications, keeping psychiatric appointments, seeking knowledge, self-monitoring, and socializing) and 2) emotion focused (distracting activities, denial, isolation, modifying/avoiding, helping others, and seeking social support). Participants used both types of coping strategies to deal with stressful situations brought about by the internal and external demands associated with self-management of BD. Conclusion This qualitative study provided a first step in evaluating coping strategies as a possible mediator in the self-management of BD and has implications for health care providers. Being able to characterize an individual’s coping behaviors can help patients modify or replace more maladaptive coping with better coping strategies in the self-management of this chronic mental illness.

To determine factors for switching to osmotic release oral system methylphenidate (OROS-MPH) among poor adherents to immediate-release methylphenidate (IR-MPH); and to compare the efficacy of OROS-MPH on the three attention-deficit/hyperactivity disorder (ADHD) subtypes in a multi-site prospective observational study in Taiwan. The sample included 240 children with ADHD, aged 6-16 years, who were poor adherents to IR-MPH, 137 of whom were switched to OROS-MPH. The child psychiatrists diagnosed the Diagnostic Statistical Manual of Mental Disorders (4th edition) ADHD subtypes and assessed the medical history, adherence, side-effects, global ADHD severity, and family/school effectiveness. Parents reported their child's behavioral symptoms. The determinants for an OROS-MPH switch were higher dosage, shorter treatment and thrice-daily administration of IR-MPH, and more severe inattention symptoms. Hyperactivity and oppositional symptoms were greater in the ADHD combined and hyperactive-impulsive subtypes than the inattentive subtype. Switching to OROS-MPH significantly improved behavioral symptoms and family/school measures, and this was most evident in the ADHD-combined group, followed by the ADHD-inattentive group. Inattention influenced not only academic performance, but also overall classroom behaviors and the parent-child relationship, with the latter two also influenced by oppositional symptoms. This study suggests better efficacy for the OROS-MPH among poor adherents to IR-MPH; however, its effectiveness varied across the three ADHD subtypes (ClinicalTrials.gov number NCT00460720).

To document the lived experiences of people with both poor mental health and suboptimal adherence to antiretroviral therapy in high HIV prevalence settings. In-depth qualitative interviews were conducted with 47 (female = 31) HIV-positive adults who scored above the cut-point on a locally validated scale for common mental disorders (CMDs). Purposive sampling was used to recruit participants with evidence of poor adherence. Six additional key informant interviews (female = 6) were conducted with healthcare workers. Data were collected and analysed inductively by an interdisciplinary coding team. The major challenges faced by participants were stressors (poverty, stigma, marital problems) and symptoms of CMDs ('thinking too much', changes to appetite and sleep, 'burdened heart' and low energy levels). Thinking too much, which appears closely related to rumination, was the symptom with the greatest negative impact on adherence to antiretroviral therapy among HIV-positive adults with CMDs. In turn, thinking too much was commonly triggered by the stressors faced by people living with HIV/AIDS, especially poverty. Finally, participants desired private counselling, access to income-generating activities and family engagement in mental health care. Better understanding of the local expression of mental disorders and of underlying stressors can inform the development of culturally sensitive interventions to reduce CMDs and poor adherence to antiretroviral therapy. © 2015 John Wiley & Sons Ltd.

We sought to determine the rates and predictors of dietary sodium restriction and to evaluate the reliability of 24-hour urine collection as a tool to estimate dietary sodium intake in heart failure (HF) patients. We evaluated the 24-hour urinary sodium excretion of 305 outpatients with HF and reduced ejection fraction who were educated on following a <2 g sodium diet. The mean sodium excretion according to a single sample from each participant was 3.15 ± 1.58 g, and 23% were adherent to the <2 g recommendation. One hundred sixty-eight participants provided 2 samples with urinary creatinine excretion within normative range. Averaging both resulted in a mean sodium excretion of 3.21 ± 1.20 g and lower adherence rates to the <2-gram diet: 14% versus 23% (P = .019). Multivariate logistic regression showed only male sex and higher body mass index (BMI) to be associated with nonadherence (male: odds ratio [OR] 2.20, 95% confidence interval [CI] 1.25-3.88; 1 unit BMI: OR 1.05, 95% CI 1.01-1.10). Bland-Altman plots of urinary sodium and creatinine showed poor reproducibility between samples. In this chronic HF population, sodium consumption probably exceeds recommended amounts, particularly in men and those with higher BMI. Urine analyses were not highly reproducible, suggesting variation in both diet and urine collection. Copyright © 2015 Elsevier Inc. All rights reserved.

Raised blood pressure (BP) remains an important risk factor for cardiovascular diseases such as stroke. Adherence to therapeutic recommendations especially antihypertensive drugs is important in BP control. The aim of the study was to assess the stroke risk factors and levels of adherence among hypertensive patients with stroke in Kampala Uganda. In a cross-sectional study we describe 112 hypertensive subjects with stroke from two Kampala city hospitals. A standardized pre-tested questionnaire was used to collect medical history, clinical details, radiological findings and laboratory data. A total of 112 hypertensive subjects with stroke were enrolled between May 2013 and April 2014. The median ages were 63.5 years (52.5-75.0) for the cases. Seventy percent (78/112) of the study participants had ischemic strokes. Only 17% were adherent to anti-hypertensive medications. The main cause of non-adherence appears to be lack of knowledge. Poor adherence of anti-hypertensive medications among hypertensive patients remains a big challenge in our setting. This has been attributed to lack of adequate knowledge and cost of the prescribed drugs. There is therefore an urgent need to promptly diagnose and educate hypertensive patients with emphasis on adherence to anti hypertensive drugs.

The effectiveness of phosphate binders in daily practice is directly related to therapeutic compliance (TC) by the patient. The goal of this study was to analyse the TC of haemodialysis patients with hyperphosphatemia and its influence on serum phosphorus for 6 months follow up. 181 patients were included, who had mean initial phosphate levels (P) >5mg/dl. TC with different phosphate binders was evaluated, considering non-adherent patients those who had <75% of TC, SMAQ scale score of "non-adherent"(Table 1), and P>5mg/dl. Patients who were adherent at baseline visit (BV) left the study, the rest continued to V5 (6 months). TC at baseline and during the follow up (V1-V5) was analysed. Phosphate binders and the evolution of phosphataemia based on treatment were assessed. 103 male and 78 female patients were evaluated, with a mean age of 59.9 (21-86) years. Of these, 39.2% (n=71) were adherent in the BV. Patients older than 60 years of age were more adherent than younger ones (P=.019).Table 6 specifies the causes of non-compliance. The remaining 60.8% of patients (n=110), were non-adherent and continued through to the end of the study. An average of 27.2% of these patients became adherent during the course of the study. Table 7 shows the relative levels of P with TC over successive visits. At the end of the study, mean P levels had decreased by 1.26mg/dl (P<.0001). Among HD patients with poor P level control, there is a low level of adherence with phosphorus binder treatment, at 39.2%. Compliance and phosphataemia are improved with different strategies. The decrease of P is higher in adherent patients than in non-adherent patients.

Poor adherence of acne patients to treatment may equate to poor clinical efficacy, increased healthcare costs, and unnecessary treatments. Authors have investigated risk factors for poor medical adherence and how to improve this difficult problem in the context of acne. This systematic review aims to describe what methods have been used to measure adherence, what is known about acne patients' adherence to treatment, and the factors affecting adherence. A MEDLINE search was performed for randomized controlled trials published between 1978 and June 2013, focusing on patient adherence to prescribed acne medications. A test for equality of proportions was performed on studies of similar design to collectively analyze adherence to oral versus topical medication. The self-reported adherence data collected from these clinical trials were then compared with adherence data from a pharmacy database study. Studies varied in modalities of data collection, but the majority utilized subjective methods. Topical therapies were more often studied than oral. The overall oral adherence rate, as calculated by a test of equality of proportions, was 76.3%, while the overall topical adherence rate was 75.8% (p=0.927). The occurrence of side effects and young age were cited as the top reasons for poor adherence, followed by forgetfulness. The MEDLINE search resulted in a limited sample of adherence studies. In addition, there is currently no standardized or fully validated method of measurement, allowing for variability in what was considered 'adherent'. Lastly, data collected via subjective methods cannot guarantee reliable results. Overall, the values reflected a population adherent to both topical and oral medications, with no significant difference in adherence between the two. However, the methodologies used by many of the studies were weak, and the findings are not consistent with results of more objective measures of adherence.

Lack of concordance between medications listed in the medical record and taken by the patient contributes to poor outcomes. We sought to determine whether patients who received health coaching by medical assistants improved their medication concordance and adherence. This was a nonblinded, randomized, controlled, pragmatic intervention trial. English- or Spanish-speaking patients, age 18 to 75 years, with poorly controlled type 2 diabetes, hypertension, and/or hyperlipidemia were enrolled from 2 urban safety net clinics and randomized to receive 12 months of health coaching versus usual care. Outcomes included concordance between medications documented in the medical record and those reported by the patient and adherence based on the patient-reported number of days (of the last 7) on which patient took all prescribed medications. The proportion of medications completely concordant increased in the coached group versus the usual care group (difference in change, 10%; P = .05). The proportion of medications listed in the chart but not taken significantly decreased in the coached group compared with the usual care group (difference in change, 17%; P = .013). The mean number of adherent days increased in the coached but not in the usual care group (difference in change, 1.08; P < .001). Health coaching by medical assistants significantly increases medication concordance and adherence. © Copyright 2015 by the American Board of Family Medicine.

The introduction of highly active antiretroviral therapy marked a major gain in efficacy of HIV/AIDS treatment and a reduction in morbidity and mortality of the infected patients. However, high levels of adherence are required to obtain virologic suppression. In Brazil, the policy of free and universal access to antiretroviral therapy has been in place since 1996, although there are reports of poor adherence. To define the clinical, demographic and psychological characteristics, and quality of life of patients with HIV/AIDS who present poor adherence to highly active antiretroviral therapy. This was a cross-sectional study. To be included in the study patients had to be 18 through 65 years old, diagnosed with HIV/AIDS, having the two previous viral loads above 500 copies, a surrogate for poor adherence to antiretrovirals. The following instruments were applied to all eligible patients: the sociodemographic questionnaire "Adherence Follow-up Questionnaire", the Beck Depression Inventory (BDI-II), the Beck Anxiety Inventory (BAI), and the 36-Item Short Form Survey. 47 patients were evaluated, 70.2% were female, mean age of 41.9 years (±10.5), 46.8% were single, 51.1% self-reported adherence ≥95%, 46.8% mentioned depression as the main reason for not taking the medication, 59.5% presented symptoms of moderate to severe depression, and 44.7% presented symptoms of moderate to severe anxiety. Finally, regarding health-related quality of life these patients obtained low scores in all dimensions, physical component summary of 43.96 (±9.64) and mental component summary of 33.19 (±13.35). The psychological component is considered to be fundamental in the management of HIV/AIDS patients. Psychoeducation should be conducted at the initial evaluation to reduce negative beliefs regarding antiretroviral therapy Assessment of anxiety and depression symptoms should be done throughout therapy as both psycological conditions are associated with patient adherence, success of

Food insecurity- lack of dependable access to adequate food-may play a role in poor diabetes control. We aimed to determine the relationship between food security status and depression, diabetes distress, medication adherence and glycemic control. Secondary analysis of baseline data from Peer Support for Achieving Independence in Diabetes, a randomized controlled trial that enrolled patients from November 2011 to October 2013. Participants had poorly controlled type 2 diabetes (A1c ≥ 8.0 % on eligibility screen), household income < 250 % of the federal poverty level, were 30-70 years old, and were recruited from a large public hospital, a VA medical center and a community-health center in King County, Washington. We measured food insecurity determined by the Department of Agriculture's 6-Item Food Security Module. Depression, diabetes distress and medication adherence measured by PHQ-8, Diabetes Distress Scale and Morisky Medication Adherence Scale, respectively. Diet was assessed through Summary of Diabetes Self-Care Activities and Starting the Conversation tool. Incidence of hypoglycemic episodes was by patient report. Glycemic control was assessed with glycosylated hemoglobin (A1c) values from fingerstick blood sample. The prevalence of food insecurity was 47.4 %. Chi-square tests revealed participants with food insecurity were more likely to be depressed (40.7 % vs. 15.4 %, p < 0.001), report diabetes distress (55.2 % vs. 33.8 %, p < 0.001) and have low medication adherence (52.9 % vs. 37.2 %, p = 0.02). Based on linear regression modeling, those with food insecurity had significantly higher mean A1c levels (β = 0.51; p = 0.02) after adjusting for sex, age, race/ethnicity, language, education, marital status, BMI, insulin use, depression, diabetes distress and low medication adherence. Almost half of participants had food insecurity. Food insecurity was associated with depression, diabetes distress, low medication adherence and worse

Adherence in severe asthma is a difficult health problem. Although psychosocial factors may be responsible for non-adherence, few longitudinal studies have investigated their link with adherence, with most studies having focused on pharmacology. Sixty patients with severe asthma were recruited. Adherence was electronically monitored using peak flow measurements at entry and after 1 year of follow-up. Eysenck's Personality Inventory, Rotter's Locus of Control (LOC), and health control beliefs were all studied. Multiple logistic regression (MLR) was used for risk calculations. Initially, subjects with poor adherence had an external LOC (P=.001) and a high extraversion score (P=.003) compared to those with good adherence. The lie score was high in all patients. Nocturnal awakenings were highly significantly correlated with poor adherence (P=.006). After 1 year, patient adherence, extraversion, and neuroticism remained unchanged. The LOC changed in subjects with poor adherence, showing a less "external" orientation (P=.007). The health parameters were better at the end of the study. By MLR analysis, externality, extraversion, and low social desirability were associated with poor adherence. Patients with poor adherence had a greater probability of nocturnal symptoms. No specific personality type was associated with lack of adherence in the present study, but a high extraversion score, a low social desirability score, and a high level of externality were all predictors of poor adherence.

Background Medication non-adherence may lead to poor therapeutic outcomes. Cognitive functions deteriorate with age, contributing to decreased adherence. Interventions have been tested to improve adherence in seniors with cognitive impairment or Alzheimer disease (AD), but high-quality systematic reviews are lacking. It remains unclear which interventions are promising. Objectives We conducted a systematic review to identify, describe, and evaluate interventions aimed at improving medication adherence among seniors with any type of cognitive impairment. Methods Following NICE guidance, databases and websites were searched using combinations of controlled and free vocabulary. All adherence-enhancing interventions and study designs were considered. Studies had to include community dwelling seniors, aged 65 years or older, with cognitive impairment, receiving at least one medication for a chronic condition, and an adherence measure. Study characteristics and methodological quality were assessed. Results We identified 13 interventions, including six RCTs. Two studies were of poor, nine of low/medium and two of high quality. Seven studies had sample sizes below 50 and six interventions focused on adherence to AD medication. Six interventions tested a behavioral, four a medication oriented, two an educational and one a multi-faceted approach. Studies rarely assessed therapeutic outcomes. All but one intervention showed improved adherence. Conclusion Three medium quality studies showed better adherence with patches than with pills for AD treatment. Promising interventions used educational or reminding strategies, including one high quality RCT. Nine studies were of low/moderate quality. High quality RCTs using a theoretical framework for intervention selection are needed to identify strategies for improved adherence in these seniors.

Adherence to treatment is a complex and poorly understood phenomenon. This study investigates the relationship between older depressed patients' adherence to antidepressants and their beliefs about and knowledge of the medication. Assessment was undertaken of 108 outpatients over the age of 55 years diagnosed with depressive disorder and treated for at least four weeks with antidepressants. Adherence was assessed using two self-report measures: the Medication Adherence Rating Scale (MARS) and a Global Adherence Measure (GAM). Potential predictors of adherence investigated included sociodemographic, medication and illness variables. In addition, 33 carers were interviewed regarding general medication beliefs. 56% of patients reported 80% or higher adherence on the GAM. Sociodemographic variables were not associated with adherence on the MARS. Specific beliefs about medicines, such as "my health depends on antidepressants" (necessity) and being less worried about becoming dependant on antidepressants (concern) were highly correlated with adherence. General beliefs about medicines causing harm or being overprescribed, experiencing medication side-effects and severity of depression also correlated with poor adherence. Linear regression with the MARS as the dependent variable explained 44.3% of the variance and showed adherence to be higher in subjects with healthy specific beliefs who received more information about antidepressants and worse with depression severity and autonomic side-effects. Our findings strongly support a role for specific beliefs about medicines in adherence. Challenging patients' beliefs, providing information about treatment and discussing side-effects could improve adherence. Poor response to treatment and medication side-effects can indicate poor adherence and should be considered before switching medications.

Correlates of Pediatric CPAP Adherence.

Obstructive sleep apnea (OSA) is a common pediatric condition characterized by recurrent partial or complete cessation of airflow during sleep, typically due to inadequate upper airway patency. Continuous positive airway pressure (CPAP) is a therapeutic option that reduces morbidity. Despite efforts to promote use, CPAP adherence is poor in both pediatric and adult populations. We sought to determine whether demographics, insurance status, OSA severity, therapeutic pressure, or comorbid conditions were associated with pediatric CPAP adherence. A retrospective review of adherence download data was performed on all pediatric patients with initiation or adjustment of CPAP treatment over a one-year period with documented in-laboratory CPAP titration. Patients were grouped as CPAP adherent or non-adherent, where adherence was defined as > 70% nightly use and average usage ≥ 4 hours per night. Differences between the groups were analyzed by χ(2) test. Overall, nearly half of participants were CPAP adherent (49%, 69/140). Of the demographic data collected (age, ethnicity, sex, insurance status), only female sex was associated with better adherence (60.9% vs 39.5% of males adherent; odds ratio [OR] = 2.41, 95%CI = 1.20-4.85; p = 0.01). Severity of OSA (diagnostic apnea-hypopnea index [AHI] and degree of hypoxemia), therapeutic pressure, and residual AHI did not impact CPAP adherence (p > 0.05). Patients with developmental delay (DD) were more likely to be adherent with CPAP than those without a DD diagnosis (OR = 2.55, 95%CI = 1.27-5.13; p = 0.007). Female patients with trisomy 21 tended to be more adherent, but this did not reach significance or account for the overall increased adherence associated with female sex. Our study demonstrates that adherence to CPAP therapy is poor but suggests that female sex and developmental delay are associated with better adherence. These findings support efforts to understand the pathophysiology of and to develop adherence

Background Poor adherence has been identified as the main cause of failure to control hypertension. Poor adherence to antihypertensive treatment is a significant cardiovascular risk factor, which often remains unrecognized. There are no previous studies that examined adherence with antihypertensive medication or the characteristics of the non-adherent patients in Bangladesh. Objective This paper aims to describe hypertension and factors affecting adherence to treatment among hypertensive persons in rural Bangladesh. Design The study population included 29,960 men and women aged 25 years and older from three rural demographic surveillance sites of the International Center for Diarrheal Disease Research, Bangladesh (icddr,b): Matlab, Abhoynagar, and Mirsarai. Data was collected by a cross-sectional design on diagnostic provider, initial, and current treatment. Discontinuation of medication at the time of interview was defined as non-adherence to treatment. Results The prevalence of hypertension was 13.67%. Qualified providers diagnosed only 53.5% of the hypertension (MBBS doctors 46.1 and specialized doctors 7.4%). Among the unqualified providers, village doctors diagnosed 40.7%, and others (nurse, health worker, paramedic, homeopath, spiritual healer, and pharmacy man) each diagnosed less than 5%. Of those who started treatment upon being diagnosed with hypertension, 26% discontinued the use of medication. Age, sex, education, wealth, and type of provider were independently associated with non-adherence to medication. More men discontinued the treatment than women (odds ratio [OR] 1.74, confidence interval [CI] 1.48–2.04). Non-adherence was greater when hypertension was diagnosed by unqualified providers (OR 1.52, CI 1.31–1.77). Hypertensive patients of older age, least poor quintile, and higher education were less likely to be non-adherent. Patients with cardiovascular comorbidity were also less likely to be non-adherent to antihypertensive medication (OR 0

Background: Lack of adherence to medication is a trigger of graft rejection in solid-organ transplant (SOT) recipients. Objective: This exploratory study aimed to assess whether a biopsychosocial evaluation using the INTERMED instrument before transplantation could identify SOT recipients at risk of suboptimal post-transplantation adherence to immunosuppressant drugs. We hypothesized that complex patients (INTERMED>20) might have lower medication adherence than noncomplex patients (INTERMED≤20). Methods: Each patient eligible for transplantation at the University Hospital of Lausanne, Switzerland, has to undergo a pre-transplantation psychiatric evaluation. In this context the patient was asked to participate in our study. The INTERMED was completed pre-transplantation, and adherence to immunosuppressive medication was monitored post-transplantation by electronic monitors for 12 months. The main outcome measure was the implementation and persistence to two calcineurin inhibitors, cyclosporine and tacrolimus, according to the dichotomized INTERMED score (>20 or ≤20). Results: Among the 50 SOT recipients who completed the INTERMED, 32 entered the study. The complex (N=11) and noncomplex patients (N=21) were similar in terms of age, sex and transplanted organ. Implementation was 94.2% in noncomplex patients versus 87.8% in complex patients (non-significant p-value). Five patients were lost to follow-up: one was non-persistent, and four refused electronic monitoring. Of the four patients who refused monitoring, two were complex and withdrew early, and two were noncomplex and withdrew later in the study. Conclusion: Patients identified as complex pre-transplant by the INTERMED tended to deviate from their immunosuppressant regimen, but the findings were not statistically significant. Larger studies are needed to evaluate this association further, as well as the appropriateness of using a nonspecific biopsychosocial instrument such as INTERMED in highly morbid

Background and purpose Vaginal stenosis (VS) after pelvic radiotherapy can impair long-term quality of life. We prospectively assessed adherence and efficacy of VD use as the primary and secondary objectives, respectively. Material and methods Women with gastrointestinal (n=63) and gynecologic (n=46) cancers self-reported use and VD size in monthly diaries for 12 months after radiotherapy. Adherence was measured as actual VD use out of recommended times over 12 months (3×/week × 52 weeks = 156). Results Among 109 participants, aged 28–81 years (median, 58 years), mean percent adherence over 12 months was 42% (95% confidence interval [CI], 36%–48%). Adherence was highest in the first quarter (56%), but fell to 25% by the fourth. Disease type, treatment sequence, and chemotherapy were predictors of adherence (all P<.05). Eighty-two percent maintained pre-RT VD size at 12 months; of 49% with decrease in VD size at 1 month post-RT, 71% returned to pre-RT VD size at 12 months. Disease type, younger age, and increased adherence at 6 months were associated with maintaining or returning to pre-RT size at 12 months (all P≤.05). Conclusions VD use is effective in minimizing VS, but adherence at 12 months was poor. Studies evaluating methods of improving adherence and determining the optimal frequency and duration of use are needed. PMID:26164775

Mediterranean Diet (MedDiet) adherence has been proven to produce numerous health benefits. In addition, nutrigenetic studies have explained some individual variations in the response to specific dietary patterns. The present research aimed to explore associations and potential interactions between MedDiet adherence and genetic background throughout the Food4Me web-based nutritional intervention. Dietary, anthropometrical and biochemical data from volunteers of the Food4Me study were collected at baseline and after 6 months. Several genetic variants related to metabolic risk features were also analysed. A Genetic Risk Score (GRS) was derived from risk alleles and a Mediterranean Diet Score (MDS), based on validated food intake data, was estimated. At baseline, there were no interactions between GRS and MDS categories for metabolic traits. Linear mixed model repeated measures analyses showed a significantly greater decrease in total cholesterol in participants with a low GRS after a 6-month period, compared to those with a high GRS. Meanwhile, a high baseline MDS was associated with greater decreases in Body Mass Index (BMI), waist circumference and glucose. There also was a significant interaction between GRS and the MedDiet after the follow-up period. Among subjects with a high GRS, those with a high MDS evidenced a highly significant reduction in total carotenoids, while among those with a low GRS, there was no difference associated with MDS levels. These results suggest that a higher MedDiet adherence induces beneficial effects on metabolic outcomes, which can be affected by the genetic background in some specific markers.

Isoniazid is a leading cause of liver injury but it is not clear how many cases are reported or how many clinicians and patients adhere to American Thoracic Society (ATS) guidelines. We collected data on cases of isoniazid hepatotoxicity and assessed adherence to ATS guidelines and reports to the Centers for Disease Control's (CDC) isoniazid severe adverse events program. We analyzed Drug-Induced Liver Injury Network (DILIN) cases considered definite, highly likely, or probable for isoniazid injury from 2004 through 2013. We assessed the delays in isoniazid discontinuance according to ATS criteria and hepatotoxicity severity by Severity Index Score. We checked reporting to the CDC by matching cases based on age, latency, indication, reporting period, and comorbidities. Isoniazid was the second most commonly reported agent in the DILIN, with 69 cases; 60 of these met inclusion criteria. The median age of cases was 49 years (range, 4-68 y), 70% were female, 97% had latent tuberculosis, and 62% were hospitalized. Patients took a median of 9 days to stop taking isoniazid (range, 0-99 days). Thirty-three cases (55%) continued taking isoniazid for more than 7 days after the ATS criteria for stopping were met. Twenty-four cases (40%) continued isoniazid for more than 14 days after meeting criteria for stopping. A delay in stopping was associated with more severe injury (P < .05). Of 13 patients who died or underwent liver transplantation, 9 (70%) continued taking isoniazid for more than 7 days after meeting criteria for stopping. Only 1 of 25 cases of isoniazid hepatotoxicity eligible for reporting to the CDC was reported. Poor adherence to ATS guidelines is common in cases of hepatotoxicity and is associated with more severe outcomes including hospitalization, death, and liver transplantation. Isoniazid continues to be a leading cause of DILI in the United States, and its hepatotoxicity is under-reported significantly. Copyright © 2015 AGA Institute. Published by

Study Objectives: Obstructive sleep apnea (OSA) is a common pediatric condition characterized by recurrent partial or complete cessation of airflow during sleep, typically due to inadequate upper airway patency. Continuous positive airway pressure (CPAP) is a therapeutic option that reduces morbidity. Despite efforts to promote use, CPAP adherence is poor in both pediatric and adult populations. We sought to determine whether demographics, insurance status, OSA severity, therapeutic pressure, or comorbid conditions were associated with pediatric CPAP adherence. Methods: A retrospective review of adherence download data was performed on all pediatric patients with initiation or adjustment of CPAP treatment over a one-year period with documented in-laboratory CPAP titration. Patients were grouped as CPAP adherent or non-adherent, where adherence was defined as > 70% nightly use and average usage ≥ 4 hours per night. Differences between the groups were analyzed by χ2 test. Results: Overall, nearly half of participants were CPAP adherent (49%, 69/140). Of the demographic data collected (age, ethnicity, sex, insurance status), only female sex was associated with better adherence (60.9% vs 39.5% of males adherent; odds ratio [OR] = 2.41, 95%CI = 1.20–4.85; p = 0.01). Severity of OSA (diagnostic apnea-hypopnea index [AHI] and degree of hypoxemia), therapeutic pressure, and residual AHI did not impact CPAP adherence (p > 0.05). Patients with developmental delay (DD) were more likely to be adherent with CPAP than those without a DD diagnosis (OR = 2.55, 95%CI = 1.27–5.13; p = 0.007). Female patients with trisomy 21 tended to be more adherent, but this did not reach significance or account for the overall increased adherence associated with female sex. Conclusions: Our study demonstrates that adherence to CPAP therapy is poor but suggests that female sex and developmental delay are associated with better adherence. These findings support efforts to understand the

HIV symptomatic or AIDS diagnosed women who had a young well child were recruited for a study investigating their adherence to antiretrovirals (N = 46). Very poor rates of adherence were found, ranging from 43% (pill count assessment) to 56% (self-report of 3-day adherence to dose). Several factors were associated with nonadherence, including alcohol use, perceived stress, having a partner and age of youngest child, poor self-efficacy to stay with treatment, and poor outcome expectancies regarding the benefits of following the treatment regimen. Interventions to assist these women in improving adherence are urgently needed.

Background: Poor adherence to the disease-modifying therapies (DMTs) for multiple sclerosis (MS) may attenuate clinical benefit. A better understanding of characteristics associated with non-adherence could improve outcomes. Objective: To evaluate characteristics associated with non-adherence to injectable DMTs. Methods: Consecutive patients from four Canadian MS Clinics were assessed at three time points over two years. Clinical and demographic information included self-reported DMT use, missed doses in the previous 30 days, health behaviors, and comorbidities. Non-adherence was defined as <80% of expected doses taken. We employed generalized estimating equations to examine characteristics associated with non-adherence at all time points with findings reported as adjusted odds ratios (OR). Results: In all, 485 participants reported use of an injectable DMT, of whom 107 (22.1%) were non-adherent over the study period. Non-adherence was associated with a lower Expanded Disability Status Scale score (0–2.5 vs 3.0–5.5, OR: 1.80; 95% confidence interval (CI): 1.06–3.04), disease duration (⩽5 vs <5 years, OR: 2.23; 95% CI: 1.10–4.52), alcohol dependence (OR: 2.14; 95% CI: 1.23–3.75), and self-reported cognitive difficulties, measured by the Health Utilities Index-3 (OR: 1.55; 95% CI: 1.08–2.22). Conclusions: Nearly one-quarter of participants were non-adherent during the study. Alcohol dependence, perceived cognitive difficulties, longer disease duration, and mild disability status were associated with non-adherence. These characteristics may help healthcare professionals identify patients at greatest risk of poor adherence. PMID:27357507

Background Participation of older people in a program of regular exercise is an effective strategy to minimize the physical decline associated with age. The purpose of this study was to assess adherence rates in older women enrolled in two different exercise programs (one aerobic exercise and one strength training) and identify any associated clinical or functional factors. Methods This was an exploratory observational study in a sample of 231 elderly women of mean age 70.5 years. We used a structured questionnaire with standardized tests to evaluate the relevant clinical and functional measures. A specific adherence questionnaire was developed by the researchers to determine motivators and barriers to exercise adherence. Results The adherence rate was 49.70% in the aerobic exercise group and 56.20% in the strength training group. Multiple logistic regression models for motivation were significant (P=0.003) for the muscle strengthening group (R2=0.310) and also significant (P=0.008) for the aerobic exercise group (R2=0.154). A third regression model for barriers to exercise was significant (P=0.003) only for the muscle strengthening group (R2=0.236). The present study shows no direct relationship between worsening health status and poor adherence. Conclusion Factors related to adherence with exercise in the elderly are multifactorial.

Secondary prevention is a priority after coronary revascularization. We investigate the impact of a cardiac rehabilitation (CR) program on lifestyle, risk factors and medication modifications and analyze predictors of poor behavioral changes and events in patients after coronary artery bypass grafting (CABG) or percutaneous coronary intervention (PCI). Multicenter (n=62), prospective, longitudinal survey in post-CABG or -PCI consecutive patients after a comprehensive CR program. Cardiac risk factors, lifestyle habits, medication and 1 year cardiovascular events were collected. Logistic regression analyzed the association between risk factors, events and predictors of non-adherence to treatment and lifestyle. At 1 year, of the 1262 patients (66 ± 10 years, CABG 69%, PCI 31%), 94% were taking antiplatelet agents (vs. 91.8% at CR admission and 91.7% at CR discharge, p=ns), 87% statins (vs. 67.5%, p<.0001, and 86.3%, p=ns), 80.7% beta-blockers (vs. 67.4%, p<.0001, and 88.8%, p=ns), and 81.1% ACE inhibitors (vs. 57.5% p<.0001, and 77.7%, p=ns). 89.9% of the patients showed good adherence to treatment, 72% adhered to diet and 51% to exercise recommendations; 74% of smokers stopped smoking. Younger age was predictive of smoking resumption (OR 8.9, CI 3.5-22.8). Pre-event sedentary lifestyle (OR 3.3, CI 1.3-8.7) was predictive of poor diet. Older patients with comorbidity (OR 3.1; CI, 1.8-5.2) tended to persist in sedentary lifestyle and discontinue therapy and diet recommendations. Age, diabetes, smoking and PCI indication were predictors of recurrent CV events which occurred in 142 patients. Participation in CR results in excellent treatment after revascularization, as well as a good lifestyle and medication adherence at 1 year and provides further confirmation of the benefit of secondary prevention. Several clinical characteristics may predict poor behavioral changes. Copyright © 2012 Elsevier Ireland Ltd. All rights reserved.

Poor adherence to therapeutic regimens is a significant impediment to improving clinical outcomes in the HF population. Typical rates of adherence to prescribed medications, low-sodium diets, and aerobic exercise programs remain lower than that needed to decrease morbidity and mortality associated with HF. Factors contributing to poor adherence include multiple comorbidities, clinical depression, and decreased cognitive functioning. HF education and programs to enhance self-management skills have improved patient quality of life but have yet to decrease mortality or rehospitalization rates significantly. Telemonitoring to improve adherence behaviors and self-management interventions within broader HF management programs have demonstrated significant clinical improvements in this population.

Background COPD affects millions of people worldwide. Poor treatment adherence contributes to increased symptom severity, morbidity and mortality. This study was designed to investigate adherence to COPD treatment in Turkey and Saudi Arabia. Methods An observational, cross-sectional study in adult COPD patients in Turkey and Saudi Arabia. Through physician-led interviews, data were collected on sociodemographics and disease history, including the impact of COPD on health status using the COPD Assessment Test (CAT); quality of life, using the EuroQol Five-Dimension questionnaire (EQ-5D); and anxiety and depression using the Hospital Anxiety and Depression Scale (HADS). Treatment adherence was measured using the 8-item Morisky Medication Adherence Scale (MMAS-8). Multivariate logistic regression analysis examined the predictors of non-adherence and the impact of adherence on symptom severity. Results Four hundred and five COPD patients participated: 199 in Turkey and 206 in Saudi Arabia. Overall, 49.2% reported low adherence (MMAS-8 <6). Of those, 74.7% reported high disease impact (CAT >15) compared to 58.4% reporting medium/high adherence (p=0.0008). Patients with low adherence reported a lower mean 3-level EQ-5D utility value (0.54±0.35) compared to those with medium/high adherence (0.64±0.30; p<0.0001). Depression with HADS score 8–10 or >10 was associated with lower adherence (OR 2.50 [95% CI: 1.43–4.39] and 2.43 [95% CI: 1.39–4.25], respectively; p=0.0008). Being a high school/college graduate was associated with better adherence compared with no high school (OR 0.57 [95% CI: 0.33–0.98] and 0.38 [95% CI: 0.15–1.00], respectively; p=0.0310). After adjusting for age, gender, and country, a significant association between treatment adherence (MMAS-8 score ≥6) and lower disease impact (CAT ≤15) was observed (OR 0.56 [95% CI: 0.33–0.95]; p=0.0314). Conclusion Adherence to COPD treatment is poor in Turkey and Saudi Arabia. Non-adherence to treatment

High Adherence Is Necessary to Realize Health Gains from Water Quality Interventions

Background Safe drinking water is critical for health. Household water treatment (HWT) has been recommended for improving access to potable water where existing sources are unsafe. Reports of low adherence to HWT may limit the usefulness of this approach, however. Methods and Findings We constructed a quantitative microbial risk model to predict gains in health attributable to water quality interventions based on a range of assumptions about pre-treatment water quality; treatment effectiveness in reducing bacteria, viruses, and protozoan parasites; adherence to treatment interventions; volume of water consumed per person per day; and other variables. According to mean estimates, greater than 500 DALYs may be averted per 100,000 person-years with increased access to safe water, assuming moderately poor pre-treatment water quality that is a source of risk and high treatment adherence (>90% of water consumed is treated). A decline in adherence from 100% to 90% reduces predicted health gains by up to 96%, with sharpest declines when pre-treatment water quality is of higher risk. Conclusions Results suggest that high adherence is essential in order to realize potential health gains from HWT. PMID:22586491

Poor nutritional intake can exacerbate the chronic disease burden in childhood cancer survivors, whereas a healthful diet serves a protective function. Few studies have provided detailed evaluations of the diet of childhood cancer survivors. This study aimed to evaluate diet quality and dietary intakes of key food groups and nutrients in a large cohort of childhood cancer survivors and whether cancer and treatment characteristics have an impact on survivors' long-term intake. Diet was assessed in 2570 adult survivors of childhood cancer enrolled in the St. Jude Lifetime cohort (mean age = 32.3 y) by using the Block food-frequency questionnaire. The Healthy Eating Index-2010 (HEI-2010) was calculated to quantify diet quality. Cancer diagnosis and treatment exposure were abstracted from medical records. Differences in HEI-2010 by patient characteristics and treatment exposure were examined by using ANCOVA. The mean ± SD HEI-2010 in childhood cancer survivors was 57.9 ± 12.4 of a maximum score of 100. Referenced to Dietary Reference Intakes, survivors consumed inadequate amounts of vitamin D, vitamin E, potassium, fiber, magnesium, and calcium (27%, 54%, 58%, 59%, 84%, and 90% of the recommended intakes) but excessive amounts of sodium and saturated fat (155% and 115% of the recommended intakes) from foods. Survivors diagnosed when <5 y of age had a lower diet quality than did those diagnosed when ≥5 y of age (mean HEI-2010 score: 56.9 compared with 58.2; P = 0.046). Survivors who received higher radiation doses to the abdomen had a lower diet quality than those who received lower doses (mean HEI-2010 scores = 58.9, 57.2, 56.7, and 56.1 for doses of 0, 1-19.9, 20-29.9, and ≥30 Gy, respectively; P = 0.02). Long-term childhood cancer survivors have poor adherence to the 2010 Dietary Guidelines for Americans. Findings reinforce the need to incorporate nutrition into cancer care to improve diet quality and to reduce morbidities. © 2016 American Society for

Background Crack cocaine use undermines adherence to highly active antiretroviral therapy (HAART). This pilot randomized clinical trial tested the feasibility and efficacy of 2 interventions based on the Information-Motivation-Behavioral Skills model to improve HAART adherence and reduce crack cocaine problems. Methods Participants were 54 adults with crack cocaine use and HIV with <90% HAART adherence. Most participants were African-American (82%) heterosexual (59%), and crack cocaine dependent (92%). Average adherence was 58% in the past 2 weeks. Average viral loads (VL) were detectable (log VL 2.97). The interventions included 6 sessions of Motivational Interviewing plus feedback and skills building (MI+), or Video information plus debriefing (Video+) over 8 weeks. Primary outcomes were adherence by 14-day timeline follow-back and Addiction Severity Index (ASI) Drug Composite Scores at 3 and 6 months. Repeated measures ANOVA assessed main effects of the interventions and interactions by condition. Results Significant increases in adherence and reductions in ASI Drug Composite Scores occurred in both conditions by 3 months and were maintained at 6 months, representing medium effect sizes. No between group differences were observed. No VL changes were observed in either group. Treatment credibility, retention, and satisfaction were high and not different by condition. Conclusions A counseling and a video intervention both improved adherence and drug problems durably among people with crack cocaine use and poor adherence in this pilot study. The interventions should be tested further among drug users with poor adherence. Video interventions may be feasible and scalable for people with HIV and drug use. PMID:21306837

Patient adherence in COPD.

Bourbeau, J; Bartlett, S J

2008-09-01

Patient adherence to treatment in chronic obstructive pulmonary disease (COPD) is essential to optimise disease management. As with other chronic diseases, poor adherence is common and results in increased rates of morbidity, healthcare expenditures, hospitalisations and possibly mortality, as well as unnecessary escalation of therapy and reduced quality of life. Examples include overuse, underuse, and alteration of schedule and doses of medication, continued smoking and lack of exercise. Adherence is affected by patients' perception of their disease, type of treatment or medication, the quality of patient provider communication and the social environment. Patients are more likely to adhere to treatment when they believe it will improve disease management or control, or anticipate serious consequences related to non-adherence. Providers play a critical role in helping patients understand the nature of the disease, potential benefits of treatment, addressing concerns regarding potential adverse effects and events, and encouraging patients to develop self-management skills. For clinicians, it is important to explore patients' beliefs and concerns about the safety and benefits of the treatment, as many patients harbour unspoken fears. Complex regimens and polytherapy also contribute to suboptimal adherence. This review addresses adherence related issues in COPD, assesses current efforts to improve adherence and highlights opportunities to improve adherence for both providers and patients.

Vitamin supplementation in bariatric aftercare is essential to prevent nutrient deficiencies; however, rates of vitamin adherence have been as low as 30 % 6 months post-surgery. Preliminary literature suggests non-adherence to prescribed treatments can be linked to demographic and psychological factors. We aimed to determine the relationship between these factors to vitamin adherence in post-bariatric surgery patients. A total of 92 bariatric patients were assessed 6 months post-surgery. Patients were administered a questionnaire collecting demographic information, psychological scores, and self-reported adherence. Nutrient deficiencies were analyzed through serum vitamin levels measured 3 and 6 months after surgery. Wilcoxon rank-sum and chi-square tests were used for analysis. Non-adherence was associated with male sex and full-time employment (p = 0.027, p = 0.015). There were no differences with respect to living situation, education level, or relationship type. Non-adherent patients did not have significantly higher scores for generalized anxiety, depressive symptoms, or avoidant behaviors. However, non-adherent patients displayed greater attachment anxiety than their adherent counterparts (p = 0.0186). Non-adherence was also associated with lower vitamin B12 levels 6 months post-surgery (p = 0.001). Male gender and full-time work have previously been shown to be associated with non-adherence. This is the first study to demonstrate that attachment anxiety is associated with poor multivitamin adherence in the post-surgical bariatric population. This result is concordant with recent literature that has demonstrated attachment anxiety is associated with poor adherence to dietary recommendations in bariatric patients 6 months postoperatively. Presurgical screening for attachment anxiety could facilitate early interventions to promote better bariatric aftercare in this group.

International guidelines recommend that severe asthma can only be diagnosed after contributory factors, including adherence, have been addressed. Accurate assessment of adherence is difficult in clinical practice. We hypothesised that electronic monitoring in children would identify nonadherence, thus delineating the small number with true severe asthma.Asthmatic children already prescribed inhaled corticosteroids were prospectively recruited and persistence of adherence assessed using electronic monitoring devices. Spirometry, airway inflammation and asthma control were measured at the start and end of the monitoring period.93 children (62 male; median age 12.4 years) were monitored for a median of 92 days. Median (range) monitored adherence was 74% (21-99%). We identified four groups: 1) good adherence during monitoring with improved control, 24% (likely previous poor adherence); 2) good adherence with poor control, 18% (severe therapy-resistant asthma); 3) poor adherence with good control, 26% (likely overtreated); and 4) poor adherence with poor control, 32%. No clinical parameter prior to monitoring distinguished these groups.Electronic monitoring is a useful tool for identifying children in whom a step up in treatment is indicated. Different approaches are needed in those who are controlled when adherent or who are nonadherent. Electronic monitoring is essential in a paediatric severe asthma clinic. Copyright ©ERS 2017.

Background Antidepressants are effective in treatment of depression, but poor adherence to medication is a major obstacle to effective care. Objective We sought to describe patient and provider level factors associated with treatment adherence. Methods This was a retrospective, observational study using medical and pharmacy claims from a large health plan, for services provided between January 2003 and January 2005. We studied a total of 4312 subjects ages 18 or older who were continuously enrolled in the health plan with a new episode of major depression and who initiated antidepressant treatment. Treatment adherence was measured by using pharmacy refill records during the first 16 weeks (acute phase) and the 17–33 weeks after initiation of antidepressant therapy (continuation phase). Measures were based on Health Plan Employer Data and Information Set (HEDIS) quality measures for outpatient depression care. Results Fifty-one percent of patients were adherent through the acute phase; of those, 42% remained adherent in the continuation phase. Receipt of follow-up care from a psychiatrist and higher general pharmacy utilization (excluding psychotropics) were associated with better adherence in both phases. Younger age, comorbid alcohol or other substance abuse, comorbid cardiovascular/metabolic conditions, use of older generation antidepressants, and residence in lower-income neighborhoods were associated with lower acute-phase adherence. Continuation-phase adherence was lower for HMO participants than for others. Conclusion In an insured population, many patients fall short of adherence to guideline recommended therapy for depression. Information from existing administrative data can be used to predict patients at highest risk of nonadherence, such as those with substance abuse, and to target interventions. PMID:17496721

Ethical considerations in adherence research.

Poor adherence to treatment is a common cause of medical treatment failure. Studying adherence is complicated by the potential for the study environment to impact adherence behavior. Studies performed without informing patients about adherence monitoring must balance the risks of deception against the potential benefits of the knowledge to be gained. Ethically monitoring a patient's adherence to a treatment plan without full disclosure of the monitoring plan requires protecting the patient's rights and upholding the fiduciary obligations of the investigator. Adherence monitoring can utilize different levels of deception varying from stealth monitoring, debriefing after the study while informing the subject that some information had been withheld in regard to the use of adherence monitoring (withholding), informed consent that discloses some form of adherence monitoring is being used and will be disclosed at the end of the study (authorized deception), and full disclosure. Different approaches offer different benefits and potential pitfalls. The approach used must balance the risk of nondisclosure against the potential for confounding the adherence monitoring data and the potential benefits that adherence monitoring data will have for the research subjects and/or other populations. This commentary aims to define various methods of adherence monitoring and to provide a discussion of the ethical considerations that accompany the use of each method and adherence monitoring in general as it is used in clinical research.

Objectives Poor adherence to medication is frequent in bipolar disorder (BD) and has been associated with several factors. To date, the relationship between low adherence and neuropsychological functioning in BD is still unclear. As age and neuropsychological functioning might have opposing influences on adherence, our aim was to investigate this link with a particular focus on the effect of age. Methods In a cross-sectional study, we included 353 patients divided into two age-groups (16–46; 47–71) from a French cohort diagnosed with BD (type I, II, NOS) and strictly euthymic. All patients had a standardized clinical and neuropsychological assessment and were categorized as high (n = 186) or low (n = 167) adherent based on their score from the Medication Adherence Rating Scale. Clinical information was collected based on a standardized interview and clinical validated scales. Neuropsychological performances were evaluated with an established standardized neuropsychological battery for bipolar disorder patients. After univariate analysis, neuropsychological and clinical predictors of low adherence were included in two age-specific stepwise multiple logistic regressions. Results A smaller number of hospitalizations (OR = 0.846, p = 0.012), a shorter illness duration (OR = 0.937, p = 0.003) and higher adverse effects (OR = 1.082, p<0.001) were associated with a greater risk of low adherence in the younger patients. In the older patients, low adherence was also predicted by a smaller number of hospitalizations (OR = 0.727, p = 0.008) and higher adverse effects (OR = 1.124, p = 0.005). Interestingly poor inhibition performance was also a significant predictor of low adherence in older patients (OR = 0.924, p = 0.030). Conclusions We found an age-specific relationship between cognitive functioning and adherence in patients with BD. Poor inhibition performances predicted low adherence in older patients only. Our results highlight the need to provide age

Background Poor adherence to inhaled corticosteroids (ICS) is a critical risk factor contributing to asthma morbidity among low-income minority adolescents. Objective This trial tested whether peer support group meetings and peer asthma messages delivered via mp3 players improved adherence to ICS. Methods Low-income African American and/or Hispanic adolescents, ages 11–16, with persistent asthma, and poor (≤ 48%) adherence to prescription ICS during the 3-week run-in were randomized to intervention or attention control groups (ATG) for the 10-week treatment. During treatment, the intervention arm participated in weekly coping peer group support sessions and received mp3 peer-recorded asthma messages promoting adherence. The ATG participated in weekly meetings with a research assistant and received an equivalent number of mp3 doctor-recorded asthma messages. Adherence was measured using self-report and the DoserCT, (Meditrac, Inc.), an electronic dose counter. The primary outcome was the difference in adherence at 10 weeks between the two arms. Results Thirty-four subjects were randomized to each arm. At 10 weeks, no statistical difference in objectively measured adherence could be detected between the two arms adjusting for baseline adherence (P = 0.929). Adherence declined in both groups over the course of the active treatment period. Participants’ in both study arms self-reported adherence was significantly higher than their objectively measured adherence at week 10 (P < 0.0001). Conclusion Improving medication adherence in longitudinal studies is challenging. Peer support and mp3-delivered peer asthma messages may not be of sufficient dose to improve outcomes. PMID:24565620

Reasons for and frequency of nonadherence to antiretroviral therapy (ART) may have changed due to pharmacological improvements. In addition, the importance of known non-pharmacologic reasons for nonadherence is unclear. We performed a cross-sectional, noninterventional, multicenter study to identify current reasons for nonadherence. Patients were categorized by physicians into the following adherence groups: good, unstable, or poor adherence. Co-variables of interest included age, sex, time since HIV diagnosis, ART duration, current ART regimen, HIV transmission route, comorbidity, HIV-1 RNA viral load (VL), and CD4 cell count. Patients self-reported the number of missed doses and provided their specific reasons for nonadherent behavior. Statistical analyses were performed using Fisher's extended exact test, Kruskal-Wallis test, and logistic regression models. Our study assessed 215 participants with good (n=162), unstable (n=36), and poor adherence (n=17). Compared to patients with good adherence, patients with unstable and poor adherence reported more often to have missed at least one dose during the last week (good 11% vs unstable 47% vs poor 63%, p <0.001). Physicians' adherence assessment was concordant with patients' self-reports of missed doses during the last week (no vs one or more) in 81% cases. Similarly, we found a strong association of physicians' assessment with viral suppression. Logistic regression analysis showed that "reduced adherence" - defined as unstable or poor - was significantly associated with patients <30 years old, intravenous drug use, history of acquired immune deficiency syndrome (AIDS), and psychiatric disorders ( p <0.05). Univariate analyses showed that specific reasons, such as questioning the efficacy/dosing of ART, HIV stigma, interactive toxicity beliefs regarding alcohol and/or party drugs, and dissatisfaction with regimen complexity, correlated with unstable or poor adherence ( p <0.05).

The standard therapy for obstructive sleep apnoea (OSA) is continuous positive airway pressure (CPAP) therapy. However, long-term adherence remains at ~50% despite improvements in behavioural and educational interventions. Based on prior work, we explored whether regularity of breathing during wakefulness might be a physiologic predictor of CPAP adherence. Of the 117 consecutive patients who were diagnosed with OSA and prescribed CPAP, 79 CPAP naïve patients were enrolled in this prospective study. During CPAP initiation, respiratory signals were collected using respiratory inductance plethysmography while wearing CPAP during wakefulness in a seated position. Breathing regularity was assessed by the coefficient of variation (CV) for breath-by-breath estimated tidal volume (V T ) and total duration of respiratory cycle (Ttot). In a derivation group (n = 36), we determined the cut-off CV value which predicted poor CPAP adherence at the first month of therapy, and verified the validity of this predetermined cut-off value in the remaining participants (validation group; n = 43). In the derivation group, the CV for estimated V T was significantly higher in patients with poor adherence than with good adherence (median (interquartile range): 44.2 (33.4-57.4) vs 26.0 (20.4-33.2), P < 0.001). The CV cut-off value for estimated V T for poor CPAP adherence was 34.0, according to a receiver-operating characteristic (ROC) curve. In the validation group, the CV value for estimated V T >34.0 confirmed to be predicting poor CPAP adherence (sensitivity, 0.78; specificity, 0.83). At the initiation of therapy, breathing regularity during wakefulness while wearing CPAP is an objective predictor of short-term CPAP adherence. © 2016 Asian Pacific Society of Respirology.

Bipolar disorder (BD) is a chronic mental illness associated with reduced quality of life, high rates of suicide, and high financial costs. Evidence indicates that psychosocial stress might play an important role in the onset and course of BD. The objective of this study was to address the gap between coping theory and the clinical use of coping strategies used to self-manage BD. In-depth interviews were conducted with a sample of 21 poorly adherent patients with BD. All interviews were audiotaped, transcribed verbatim, and analyzed using content analysis with an emphasis on dominant themes. Transcript-based analysis generated two major domains of coping strategies used to self-manage BD: 1) problem focused (altering eating habits, managing mood-stabilizing medications, keeping psychiatric appointments, seeking knowledge, self-monitoring, and socializing) and 2) emotion focused (distracting activities, denial, isolation, modifying/avoiding, helping others, and seeking social support). Participants used both types of coping strategies to deal with stressful situations brought about by the internal and external demands associated with self-management of BD. This qualitative study provided a first step in evaluating coping strategies as a possible mediator in the self-management of BD and has implications for health care providers. Being able to characterize an individual's coping behaviors can help patients modify or replace more maladaptive coping with better coping strategies in the self-management of this chronic mental illness.

Adherence to treatment is important and relevant in HIV treatment. Previous studies in sub Sahara Africa and south western Nigeria reported that psychiatric morbidity influence treatment adherence. The present study was to examine treatment adherence among the male and the female patients with HIV infection and the effect of socioeconomic factors and psychiatric morbidity on treatment adherence. A total of 159 patients which comprised of 48 male and 111 female who were eligible for this cross sectional prospective study were included having given their consent to participate. Questionnaire relating to socioeconomic factors and treatment adherence were administered. Psychiatric morbidity was assessed using HADS. Data was analyzed with SPSS for windows version 16.0. Treatment adherence was poor in 5.3% of the patients. The male patients had slightly better adherence than the female patients. Factors associated with poor treatment adherence include poor clinic attendance, presence of anxiety symptoms in males and poor education attainment in females. Treatment adherence is related to socioeconomic factors and psychiatric morbidity. Treatment protocol in which mental health and detailed socioeconomic circumstance of patient is an integral part should be encouraged.

Poor adherence to efficacious cardiovascular related medications has led to considerable morbidity, mortality, and avoidable health care costs. This paper provides results of a recent think tank meeting in which various stakeholder groups representing key experts from consumers, community health providers, the academic community, decision-making government officials (FDA, NIH, etc), and industry scientists met to evaluate the current status of medication adherence and provide recommendations for improving outcomes. Below, we review the magnitude of the problem of medication adherence, prevalence, impact, and cost. We then summarize proven effective approaches and conclude with a discussion of recommendations to address this growing and significant public health issue of medication non adherence. PMID:21884856

Knowledge of adherence to highly active antiretroviral treatment (HAART) and the variables associated with poor compliance is useful for the follow-up of HIV infected patients. Patients were consecutively recruited from the HIV outpatient clinics of the Hospitals of Leon and El Bierzo from January to June 2000. Patients were considered non-adherent to treatment if they failed to take 10% or more of their prescribed total dose of at least one drug during the 4 days before the interview, or if they had accumulated a delay of more than 9 days over the previous 3 months in picking up their prescribed drugs from the hospital pharmacy. Logistic regression analysis was performed with variables found to be associated with adherence in the univariate analysis. The methods used to determine adherence had a Kappa index of 12.6%. Among the 206 patients interviewed, 108 were considered non-adherent (52.4%; CI 95% 5 45.6-59.2). Multivariate analysis showed that the following factors were associated with poor treatment adherence: cocaine consumption in the previous six months (adjusted OR 5 5.1); patients unsure about the proper way to take prescribed treatment; (adjusted OR 5 2.5); and patients not prescribed the zidovudine-lamivudine combination (adjusted OR 5 1.9). Over one-third of patients with no variable associated with treatment adherence were considered non-compliant. Measurement of medication adherence and its predictive factors involved methodological difficulties. With the criteria used in the present study more than half the patients were considered non-compliant. The variables found to be related to poor adherence can be modified by social, psychological or health care interventions.

BACKGROUND Poor adherence to antihypertensives has been shown to be a significant factor in poor blood pressure (BP) control. Providers' communication with patients about their medication-taking behavior may be central to improving adherence. OBJECTIVE The goal of this study was to characterize the ways in which providers ask patients about medication taking. DESIGN Clinical encounters between primary care providers and hypertensive patients were audiotaped at 3 Department of Veterans' Affairs medical centers. PARTICIPANTS Primary care providers (n =9) and African-American and Caucasian patients (n =38) who were diagnosed with hypertension (HTN). APPROACH Transcribed audiotapes of clinical encounters were coded by 2 investigators using qualitative analysis based on sociolinguistic techniques to identify ways of asking about medication taking. Electronic medical records were reviewed after the visit to determine the BP measurement for the day of the taped encounter. RESULTS Four different aspects of asking about medication were identified: structure, temporality, style and content. Open-ended questions generated the most discussion, while closed-ended declarative statements led to the least discussion. Collaborative style and use of lay language were also seen to facilitate discussions. In 39% of encounters, providers did not ask about medication taking. Among patients with uncontrolled HTN, providers did not ask about medications 33% of the time. CONCLUSION Providers often do not ask about medication-taking behavior, and may not use the most effective communication strategies when they do. Focusing on the ways in which providers ask about patients' adherence to medications may improve BP control. PMID:16808739

To identify the determinants of adherence to immediate-release (IR) methylphenidate in children and adolescents with attention-deficit/hyperactivity disorder (ADHD); to examine the impact of adherence on ADHD-related symptoms; and to compare the efficacy, adherence, and side effects of IR methylphenidate and osmotic release oral system (OROS) methylphenidate. This national survey, involving 12 hospitals, consisted of 2 phases of assessment. Treatment adherence in 240 (39.5%) of the 607 children aged 5 to 16 years with a clinical diagnosis of DSM-IV ADHD enrolled in the study was poor (defined as missing >or= 1 dose of ADHD medication a day and on 2 days or more during school days). Children with poor adherence at phase 1 were able to switch to OROS methylphenidate, while adherents remained on the IR variant. We reassessed 124 poor adherents who switched to OROS methylphenidate. The global ADHD severity, parent-child interaction, classroom behavior, academic performance, and side effects of the child subjects were evaluated by investigators. Parents completed the rating scales about the ADHD-related symptoms. The study began in April 2005 and was completed in February 2006. Determinants for poor adherence included older age, later onset of ADHD, family history of ADHD, higher paternal education level, and multi-dose administration. Mental retardation and treatment at medical centers were inversely related to poor adherence. Overall, poor adherence was associated with more severe ADHD-related symptoms by comparison to good adherence. Similar side effect profile, superior adherence, and improved efficacy were demonstrated in intra-individual comparison of the OROS and IR methylphenidate forms. Given that poor adherence to medication may be an important reason for suboptimal outcome in ADHD treatment, physicians should ensure adherence with therapy before adjusting dosage or switching medication. clinicaltrials.gov Identifier NCT00460720.

Patient adherence and effective communication.

Poor adherence to inhaled corticosteroid medication is a critical problem for asthma because it contributes to morbidity and mortality through poor asthma control, frequent asthma exacerbations, acute care visits, and oral corticosteroid use. To discuss evidence-based, time-efficient strategies that can be adopted by most practitioners to try to increase patient adherence. Asthma management guidelines and other key publications are used to enhance discussion. Establishing patient-centered, collaborative care that permits effective patient-practitioner communication can improve adherence, thus leading to improved asthma outcomes. One critical strategy is shared decision making, in which the patient and the practitioner share relevant information, discuss risks vs benefits of various treatment options, express treatment preferences, deliberate the options, and agree on treatment. Asthma self-management education, which emphasizes self-efficacy, is also essential. The education necessary to provide those skills depends in part on consideration of the patient's health literacy. Practitioners also have at their disposal a variety of tips and techniques to improve communication and gather information not only at the patient-practitioner level but also at the practitioner-practitioner level, such as within a group practice or within a health care system. To improve patient adherence, clinicians need to consider a variety of factors and implement strategies that directly target underlying issues. Strategies may include customizing and simplifying learning and intervention regimens, identifying barriers to adherence and addressing them, ensuring patient support structures are in place, and improving self-efficacy and health literacy.

Continuous positive airway pressure (CPAP) is a highly efficacious treatment for obstructive sleep apnea (OSA) but adherence to the treatment limits its overall effectiveness across all age groups of patients. Factors that influence adherence to CPAP include disease and patient characteristics, treatment titration procedures, technological device factors and side effects, and psychological and social factors. These influential factors have guided the development of interventions to promote CPAP adherence. Various intervention strategies have been described and include educational, technological, psychosocial, pharmacological, and multi-dimensional approaches. Though evidence to date has led to innovative strategies that address adherence in CPAP-treated children, adults, and older adults, significant opportunities exist to develop and test interventions that are clinically applicable, specific to subgroups of patients likely to demonstrate poor adherence, and address the multifactorial nature of CPAP adherence. The translation of CPAP adherence promotion interventions to clinical practice is imperative to improve health and functional outcomes in all persons with CPAP-treated OSA. PMID:21652236

Type 2 diabetes is becoming common among people in their 20s and 30s. Glycaemic control is suboptimal in this group and is associated with poor medication adherence. We studied medication adherence over a 24-month period in all diabetes clinic registrants (n = 266) between the ages of 18 and 39 years. We reviewed their glycaemic control using mean HbA1c over the study period and examined hospital records to determine the number of hospital attendances during this time. We found that less than half the group (47%) had good adherence (>90%) and 21% of the group had very poor adherence (<50%). Mean adherence was slightly poorer in women compared to men (73% vs 76%, P = 0.04). There was a marked inverse relationship between adherence and glycaemic control. Mean HbA1c is 70 mmol/mol among those with good adherence and mean HbA1c is 97 mmol/mol among those with very poor adherence (P < 0.05). Fifty-seven per cent of the study group had at least one hospital attendance during this time. Eighty-eight hospital attendances were due to a medical cause. Study of trend showed more medical admissions among those with very poor adherence (P = 0.03). Mean HbA1c was higher in those who required medical admissions (87 mmol/mol vs 75 mmol/mol) when compared to those with no hospital attendance. Our study shows that poor adherence is common and significantly related to glycaemic control as well as unplanned hospital attendances for medical conditions. Despite limitations, our study provides valuable information on medication adherence and its impact on glycaemic control and morbidity among young people with type 2 diabetes. © 2018 Royal Australasian College of Physicians.

Antiretroviral therapy (ART) is a lifelong treatment. To date, ART adherence is suboptimal for most patients in resource-poor settings. Previous research indicates that medication side effects are perceived to be a significant barrier of high ART adherence. Data regarding the role of adherence self-efficacy in mediating the relationship between side effects from ART and adherence to ART are limited; thus, this study examines this potential mediational role of self-efficacy. A cross-sectional survey of 2987 people living with HIV aged ≥18 years was conducted in 2012-2013 in Guangxi Autonomous Region (Guangxi) which has one of the fastest-growing HIV rates in China. Of the total sample, 2146 (72.1%) participants had initiated ART. Participants reported the number of days of completing the daily dose of ART in the past month; adherence was defined as completing the daily dose at least 28 days in the last month (≥90%). Side effects were significantly negatively related to adherence to ART. Mediation analyses indicated that adherence self-efficacy significantly mediated the side effects-adherence relationship. Future interventions to increase adherence self-efficacy and effective coping with side effects among HIV patients are needed in order to improve their ART adherence.

Background: WHO guidelines recommend integrating calcium supplementation into antenatal care (ANC) alongside iron and folic acid (IFA) to reduce maternal mortality. However, supplementation programs face multiple barriers, and strategies to improve adherence are needed. An adherence partner is someone whom pregnant women ask to support adherence at home. Objectives: This study 1 ) assessed adherence partner acceptability, feasibility, and associations with calcium and IFA supplement adherence and 2 ) examined relations between social support and adherence. Methods: This secondary analysis is from a trial integrating calcium supplementation into ANC in Kenya. ANC providers were trained on calcium and IFA supplementation and counseling, provided with behavior change materials, and given adequate supplement supplies. Pregnant women from 16 government health facilities were recruited ( n = 1036); sociodemographic and adherence data were collected at baseline and at 4- to 6-wk follow-up visits. Adherence was measured with pill counts and self-reports. Culturally adapted scales measured social support in general and specific to adherence. Mixed-effects regression analyses were used to examine factors associated with adherence partners, social support, and adherence. Results: Most participants received information about adherence partners (91%) and had a partner at follow-up (89%). Participants with adherence partners reported higher adherence support (OR: 2.10; 95% CI: 1.32, 3.34). Mean ± SD adherence was high for calcium (88.3% ± 20.7%) and IFA (86.1% ± 20.9%). Adherence support was positively associated with calcium adherence at follow-up by using pill counts (OR: 2.2; 95% CI: 1.1, 2.6) and self-report data (OR: 1.9; 95% CI: 1.2, 2.9), but there was not a direct relation between adherence partners and adherence. Conclusions: Adherence support enhanced adherence to calcium supplements. The adherence partner strategy was highly acceptable and feasible but warrants

Although evidence shows that poor air quality can harm human health, we have a limited understanding about the behavioural impact of air quality forecasts. Our aim was to understand to what extent air quality warning systems influence protective behaviours in the general public, and to identify the demographic and psychosocial factors associated with adherence and non-adherence to the health advice accompanying these warnings. In August 2016 literature was systematically reviewed to find studies assessing intended or actual adherence to health advice accompanying air quality warning systems, and encouraging people to reduce exposure to air pollution. Predictors of adherence to the health advice and/or self-reported reasons for adherence or non-adherence were also systematically reviewed. Studies were included only if they involved participants who were using or were aware of these warning systems. Studies investigating only protective behaviours due to subjective perception of bad air quality alone were excluded. The results were narratively synthesised and discussed within the COM-B theoretical framework. Twenty-one studies were included in the review: seventeen investigated actual adherence; three investigated intended adherence; one assessed both. Actual adherence to the advice to reduce or reschedule outdoor activities during poor air quality episodes ranged from 9.7% to 57% (Median = 31%), whereas adherence to a wider range of protective behaviours (e.g. avoiding busy roads, taking preventative medication) ranged from 17.7% to 98.1% (Median = 46%). Demographic factors did not consistently predict adherence. However, several psychosocial facilitators of adherence were identified. These include knowledge on where to check air quality indices, beliefs that one's symptoms were due to air pollution, perceived severity of air pollution, and receiving advice from health care professionals. Barriers to adherence included: lack of understanding of the indices

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

Medication Adherence: WHO Cares?

The treatment of chronic illnesses commonly includes the long-term use of pharmacotherapy. Although these medications are effective in combating disease, their full benefits are often not realized because approximately 50% of patients do not take their medications as prescribed. Factors contributing to poor medication adherence are myriad and include those that are related to patients (eg, suboptimal health literacy and lack of involvement in the treatment decision–making process), those that are related to physicians (eg, prescription of complex drug regimens, communication barriers, ineffective communication of information about adverse effects, and provision of care by multiple physicians), and those that are related to health care systems (eg, office visit time limitations, limited access to care, and lack of health information technology). Because barriers to medication adherence are complex and varied, solutions to improve adherence must be multifactorial. To assess general aspects of medication adherence using cardiovascular disease as an example, a MEDLINE-based literature search (January 1, 1990, through March 31, 2010) was conducted using the following search terms: cardiovascular disease, health literacy, medication adherence, and pharmacotherapy. Manual sorting of the 405 retrieved articles to exclude those that did not address cardiovascular disease, medication adherence, or health literacy in the abstract yielded 127 articles for review. Additional references were obtained from citations within the retrieved articles. This review surveys the findings of the identified articles and presents various strategies and resources for improving medication adherence. PMID:21389250

Despite increased awareness, poor adherence to treatments for chronic diseases remains a global problem. Adherence issues are common in patients taking antihypertensive therapy and associated with increased risks of coronary and cerebrovascular events. Whilst there has been a gradual trend toward improved control of hypertension, the number of patients with blood pressure values above goal has remained constant. This has both personal and economic consequences. Medication adherence is a multifaceted issue and consists of three components: initiation, implementation, and persistence. A combination of methods is recommended to measure adherence, with electronic monitoring and drug measurement being the most accurate. Pill burden, resulting from free combinations of blood pressure lowering treatments, makes the daily routine of medication taking complex, which can be a barrier to optimal adherence. Single-pill fixed-dose combinations simplify the habit of medication taking and improve medication adherence. Re-packing of medication is also being utilized as a method of improving adherence. This paper presents the outcomes of discussions by a European group of experts on the current situation of medication adherence in hypertension.

To determine the frequency of low-tidal volume ventilation in pediatric acute respiratory distress syndrome and assess if any demographic or clinical factors improve low-tidal volume ventilation adherence. Descriptive post hoc analysis of four multicenter pediatric acute respiratory distress syndrome studies. Twenty-six academic PICU. Three hundred fifteen pediatric acute respiratory distress syndrome patients. All patients who received conventional mechanical ventilation at hours 0 and 24 of pediatric acute respiratory distress syndrome who had data to calculate ideal body weight were included. Two cutoff points for low-tidal volume ventilation were assessed: less than or equal to 6.5 mL/kg of ideal body weight and less than or equal to 8 mL/kg of ideal body weight. Of 555 patients, we excluded 240 for other respiratory support modes or missing data. The remaining 315 patients had a median PaO2-to-FIO2 ratio of 140 (interquartile range, 90-201), and there were no differences in demographics between those who did and did not receive low-tidal volume ventilation. With tidal volume cutoff of less than or equal to 6.5 mL/kg of ideal body weight, the adherence rate was 32% at hour 0 and 33% at hour 24. A low-tidal volume ventilation cutoff of tidal volume less than or equal to 8 mL/kg of ideal body weight resulted in an adherence rate of 58% at hour 0 and 60% at hour 24. Low-tidal volume ventilation use was no different by severity of pediatric acute respiratory distress syndrome nor did adherence improve over time. At hour 0, overweight children were less likely to receive low-tidal volume ventilation less than or equal to 6.5 mL/kg ideal body weight (11% overweight vs 38% nonoverweight; p = 0.02); no difference was noted by hour 24. Furthermore, in the overweight group, using admission weight instead of ideal body weight resulted in misclassification of up to 14% of patients as receiving low-tidal volume ventilation when they actually were not.

To determine the associations between medical, demographic, socioeconomic, and ocular factors and adherence to topical glaucoma ocular hypotensive therapy. One hundred sixteen patients with ocular hypertension or open-angle glaucoma from 2 tertiary glaucoma services participated in this prospective study. Adherence to ocular hypotensive therapy was measured using an electronic dose monitor (Travatan Dosing Aid, Alcon Laboratories Inc., Fort Worth, TX) and collected data at 3 months after enrollment. We used 3 different definitions of adherence: 1) Definition 1: the proportion of days taking the prescribed number of drops within 3 hours of the prescribed dosing time; 2) Definition 2: the proportion of days taking any drops within 3 hours of the prescribed dosing time; and 3) Definition 3: the proportion of days taking any drops within 6 hours of the prescribed dosing time. Univariate and multivariate models were used to determine the association between the 3 adherence definitions, medical, demographic, socioeconomic, and ocular factors at 3-month follow-up. The main outcome measures for this study were risk factors for poor objective medication adherence. Adherence, using Definition 1, Definition 2, and Definition 3, was 64%, 75%, and 80%, respectively. Age, total number of other eye diseases, and race were significantly associated with full treatment adherence (Definition 1), with race alone significantly predicting 11% of full treatment adherence. For Definition 2, age, income, level of education, and total number of eye diseases were significantly associated with partial adherence (3 h), again race alone significantly predicted 15% of partial adherence (any drops within 3 h). For Definition 3, race, income, level of education, and total number of other eye diseases significantly predicted partial adherence (any drops within 6 h), both race and income predicted 19% of partial treatment adherence. Significant differences for adherence rates between patients of

BACKGROUND The factors influencing medication adherence have not been fully elucidated. Inadequate health literacy skills may impair comprehension of medical care instructions, and thereby reduce medication adherence. OBJECTIVES To examine the relationship between health literacy and medication refill adherence among Medicare managed care enrollees with cardiovascular-related conditions. RESEARCH DESIGN Prospective cohort study. SUBJECTS New Medicare enrollees from 4 managed care plans who completed an in-person survey and were identified through administrative data as having coronary heart disease, hypertension, diabetes mellitus, and/or hyperlipidemia (n=1,549). MEASURES Health literacy was determined using the short form of the Test of Functional Health Literacy in Adults (S-TOFHLA). Prospective administrative data were used to calculate the cumulative medication gap (CMG), a valid measure of medication refill adherence, over a 1-year period. Low adherence was defined as CMG≥20%. RESULTS Overall, 40% of the enrollees had low refill adherence. Bivariate analyses indicated that health literacy, race/ethnicity, education, and regimen complexity were each related to medication refill adherence (P<.05). In unadjusted analysis, those with inadequate health literacy skills had increased odds (odds ratio [OR]=1.37, 95% confidence interval [CI]: 1.08 to 1.74) of low refill adherence compared with those with adequate health literacy skills. However, the OR for inadequate health literacy and low refill adherence was not statistically significant in multivariate analyses (OR=1.23, 95% CI: 0.92 to 1.64). CONCLUSIONS The present study suggests, but did not conclusively demonstrate, that low health literacy predicts poor refill adherence. Given the prevalence of both conditions, future research should continue to examine this important potential association. PMID:17105519

Background The Middle East region has one the highest prevalence rates of diabetes in the world. Little is known about the determinants of adherence and the role of knowledge in diabetes self-management within these populations. Objective To investigate the relationship between patients knowledge of diabetes therapeutic targets with adherence to self-care measures in a sample of patients with type 2 diabetes in Kuwait. Setting Primary care chronic care clinics within the Ministry of Health of Kuwait. Methods A cross sectional survey was carried out with 238 patients from six clinics. A multistage stratified clustered sampling method was used to first randomly select the clinics and the patients. Self-reported adherence to three behaviours: medication taking, diet and physical activity. Results Respondents were able to correctly report a mean (SD) of 1.6 (1.3) out of 5 of the pre-specified treatment targets. Optimal adherence to physical activity, diet and medications was reported in 25, 33 and 47 % of the study cohort, respectively. A structural equation model analysis showed better knowledge of therapeutic goals and own current levels translated into better adherence to medications, diet and physical activity. Conclusion Knowledge of therapeutic goals and own recent levels is associated with adherence to medications, diet, or physical activity in this Kuwaiti cohort of patients with diabetes. Low adherence to self-care management and poor overall knowledge of diabetes is a big challenge to successful diabetes care in Kuwait.

To examine the association between adherence to the Mediterranean diet and academic performance in children and adolescents. This is a cross-sectional study conducted with 1371 youth aged 12.04 ± 2.50 years (685 girls) in Spain during 2011-2012. Adherence to the Mediterranean diet was assessed using the KIDMED index (Mediterranean Diet Quality Index in children and adolescents), which includes 16 questions on specific dietary patterns. Levels of adherence were classified into three groups: poor adherence (0-3), average adherence (4-7), and good adherence (8-12). Academic performance was assessed through school records using four indicators: math, language, an average of math and language, and grade point average score. Adherence to the Mediterranean diet was related to academic performance (β ranging from 0.107 to 0.148; all P < 0.001) after adjusting for confounders. The group of good adherence to the Mediterranean diet had significantly higher scores in all of the academic indicators compared with the poor group (ranging from +0.429 to 0.464; all P ≤ 0.001); as well as the group of average adherence to the Mediterranean diet had significantly higher scores in all of the academic indicators compared with the poor group (ranging from +0.292 to 0.344; all P ≤ 0.06). There were no differences between the groups of good and average adherence to the Mediterranean diet. Adherence to the Mediterranean diet may have a beneficial influence on academic performance in youth. Importantly, the benefits of adherence to the Mediterranean diet on academic performance may be stronger as youth adhered to the optimal Mediterranean diet levels.

One hundred and twenty-nine male partners of pregnant women who participated in the Rotterdam Periconception Cohort (Predict study). None. Semen quality parameters-ejaculate volume, sperm concentration, total sperm count, progressive motility, immotile sperm, and total motile sperm count (TMSC). Men included in our study were on average 35 (±6 standard deviation) years old and had a body mass index of 26.4 ± 4 kg/m 2 . Two dietary patterns were identified using principle component analysis, which were labeled as "healthy" and "unhealthy." An increase of one factor score (stated as β) represented an increase of 1 standard deviation. Sperm concentration (β = 0.278; 95% CI, 0.112-0.444), total sperm count (β = 1.369; 95% CI, 0.244-2.495), progressive motility (β = 4.305; 95% CI, 0.675-7.936), and TMSC (β = 0.319; 95% CI, 0.113-0.526) were all positively associated with a strong adherence to the healthy dietary pattern. Subgroup analysis showed that these associations were mainly present in men with a TMSC <10 million spermatozoa. Although there was a trend toward a diminution in semen quality, we found no statistically significant associations with strong adherence to the unhealthy dietary pattern. The positive associations between strong adherence to a healthy dietary pattern and semen parameters in men with poor semen quality support the importance of preconceptional tailored nutritional counseling and coaching of couples who are trying to conceive.

Background Alcohol use disorders (AUDs) are highly prevalent and associated with non-adherence to antiretroviral therapy, decreased health care utilization and poor HIV treatment outcomes among HIV-infected individuals. Objectives To systematically review studies assessing the impact of AUDs on: (1) medication adherence, (2) health care utilization and (3) biological treatment outcomes among people living with HIV/AIDS (PLWHA). Data Sources Six electronic databases and Google Scholar were queried for articles published in English, French and Spanish from 1988 to 2010. Selected references from primary articles were also examined. Review Methods Selection criteria included: 1) AUD and adherence (N=20); 2) AUD and health services utilization (N=11); or 3) AUD with CD4 count or HIV-1 RNA treatment outcomes (N=10). Reviews, animal studies, non-peer reviewed documents and ongoing studies with unpublished data were excluded. Studies that did not differentiate HIV+ from HIV- status and those that did not distinguish between drug and alcohol use were also excluded. Data were extracted, appraised and summarized. Data Synthesis and Conclusions Our findings consistently support an association between AUDs and decreased adherence to antiretroviral therapy and poor HIV treatment outcomes among HIV-infected individuals. Their effect on health care utilization, however, was variable. PMID:20705402

Behavioral and Pharmacological Adherence in Pediatric Sickle Cell Disease: Parent-Child Agreement and Family Factors Associated With Adherence.

2018-01-01

This study aimed to evaluate agreement between children and parents on a measure of behavioral and pharmacological adherence in children with sickle cell disease (SCD), and the associations among family factors (i.e., problem-solving skills, routines, communication) and adherence behaviors. In all, 85 children (aged 8-18 years) with SCD and their parents completed questionnaires assessing individual and family factors. Overall parent-child agreement on an adherence measure was poor, particularly for boys and older children. Greater use of child routines was associated with better overall child-reported adherence. Open family communication was associated with higher overall parent-reported adherence. While further research is needed before definitive conclusions can be drawn, results suggest the need to assess child adherence behaviors via both child and parent reports. Findings also suggest that more daily family routines and open family communication may be protective factors for better disease management. © The Author 2017.

2017-01-01

Background Existing studies have suggested decreased adherence and rebound in mortality in perinatally HIV-infected adolescents receiving antiretroviral therapy (ART) as compared to adults and young children. Methods We used both quantitative and qualitative approaches to identify factors influencing adherence among perinatally infected adolescents in Thailand. We analyzed data from 568 pairs of perinatally infected adolescents (aged 12–19) and their primary caregivers in the Teens Living With Antiretrovirals (TEEWA) study, a cross-sectional survey conducted in 2010–2012. We also conducted 12 in-depth interviews in 2014 with infected adolescents or their primary caregivers to elicit experiences of living with long-term ART. Results From the quantitative analysis, a total of 275 (48.4%) adolescents had evidence of suboptimal adherence based on this composite outcome: adolescents self-reported missing doses in the past 7 days, caregiver rating of overall adherence as suboptimal, or latest HIV-RNA viral load ≥1000 copies/ml. In multivariate logistic regression analysis, younger age, having grandparents or extended family members as the primary caregiver, caregiver-assessed poor intellectual ability, having a boy/girlfriend, frequent online chatting, self-reported unhappiness and easiness in asking doctors questions were significantly associated with suboptimal adherence. From the in-depth interviews, tensed relationships with caregivers, forgetfulness due to busy schedules, and fear of disclosing HIV status to others, especially boy/girlfriends, were important contributors to suboptimal adherence. Social and emotional support and counseling from peer group was consistently reported as a strong adherence-promoting factor. Conclusion Our findings highlight unique barriers of ART adherence among the perinatally infected adolescents. Future interventions should be targeted at helping adolescents to improve interpersonal relationships and build adaptive skills in

Poor retention in care and non-adherence to antiretroviral therapy (ART) continue to undermine the success of HIV treatment and care programmes across the world. There is a growing recognition that multifaceted interventions - application of two or more adherence-enhancing strategies - may be useful to improve ART adherence and retention in care among people living with HIV/AIDS. Empirical evidence shows that multifaceted interventions produce better results than interventions based on a singular perspective. Nevertheless, the bundle of mechanisms by which multifaceted interventions promote ART adherence are poorly understood. In this paper, we reviewed theories on ART adherence to identify candidate/potential mechanisms by which the adherence club intervention works. We searched five electronic databases (PubMed, EBSCOhost, CINAHL, PsycARTICLES and Google Scholar) using Medical Subject Headings (MeSH) terms. A manual search of citations from the reference list of the studies identified from the electronic databases was also done. Twenty-six articles that adopted a theory-guided inquiry of antiretroviral adherence behaviour were included for the review. Eleven cognitive and behavioural theories underpinning these studies were explored. We examined each theory for possible 'generative causality' using the realist evaluation heuristic (Context-Mechanism-Outcome) configuration, then, we selected candidate mechanisms thematically. We identified three major sets of theories: Information-Motivation-Behaviour, Social Action Theory and Health Behaviour Model, which explain ART adherence. Although they show potential in explaining adherence bebahiours, they fall short in explaining exactly why and how the various elements they outline combine to explain positive or negative outcomes. Candidate mechanisms indentified were motivation, self-efficacy, perceived social support, empowerment, perceived threat, perceived benefits and perceived barriers. Although these candidate

The aim of this study was to assess adherence in people on hemodialysis and determine the factors of poor adherence. This cross-sectional study took place throughout the month of September, 2012, in the hemodialysis center of the Sylvanus Olympio University Hospital, the only such center in Togo. The study included 65 patients, with a mean age of 49.5 years (range: 22 to 77 years), more often men (sex ratio: 1.82) and married (74 %). More than half (58%) had completed secondary education, while 73% belonged to the least advantaged socioeconomic class; 61 (94%) had health insurance, and 57% had been on dialysis for 1 to 4 years. The compliance rate was 11%. The main factors associated with good adherence were marital status (p = 0.0339) and the patient's general health status (p = 0.001). Treatment fatigue (p = 0.0347), forgetfulness (p = 0.0001), dosage forms and drug characteristics (p = 0.0198) were all factors of noncompliance. Therapeutic non-compliance was proportional to the number of drugs prescribed (p = 0.4263). Adherence in hemodialysis patients in Togo is very poor.

Purpose Poor adherence to prescribed medications is a major cause for treatment failure, particularly in chronic diseases such as hypertension. This study was conducted to assess adherence to medications in patients undergoing hypertensive treatment in the Primary Health Clinics of the Ministry of Health in Malaysia. Factors affecting adherence to medications were studied, and the effect of nonadherence to blood pressure control was assessed. Patients and methods This was a cross-sectional study to assess adherence to medications by adult patients undergoing hypertensive treatment in primary care. Adherence was measured using a validated survey form for medication adherence consisting of seven questions. A retrospective medication record review was conducted to collect and confirm data on patients’ demographics, diagnosis, treatments, and outcomes. Results Good adherence was observed in 53.4% of the 653 patients sampled. Female patients were found to be more likely to adhere to their medication regime, compared to their male counterparts (odds ratio 1.46 [95% confidence intervals [CI]: 1.05–2.04; P < 0.05]). Patients in the ethnic Chinese were twice as likely (95% CI: 1.14–3.6; P < 0.05) to adhere, compared to those in the Indian ethnic group. An increase in the score for medicine knowledge was also found to increase the odds of adherence. On the other hand, increasing the number of drugs the patient was taking and the daily dose frequencies of the medications prescribed were found to negatively affect adherence. Blood pressure control was also found to be worse in noncompliers. Conclusion The medication adherence rate was found to be low among primary care hypertensive patients. A poor adherence rate was found to negatively affect blood pressure control. Developing multidisciplinary intervention programs to address the factors identified is necessary to improve adherence and, in turn, to improve blood pressure control. PMID:22969292

Allergies are steadily gaining in importance in the Western world. For over one hundred years, immunology has been the only causal treatment. Specific immunotherapy (SIT) aims at the cure of allergy or at least freedom from allergy symptoms. In association with this, adherence poses a complex problem. Both treatment applications commonly used in Germany-sublingual and subcutaneous immunotherapy-show poor persistence on the part of the patients. In most cases, SIT is not carried out to the end of the recommended duration and instead is discontinued prematurely. Corresponding figures from 3‑year studies in the literature range from 41- 93% for uncompleted SLIT and from 40-77% for uncompleted SCIT. Patient adherence is subject to influencing factors of various dimensions that are interdependent in complex relationships. The physician-patient relationship is just as decisive a factor for treatment success as the patient's understanding of allergy, treatment, and the importance of adherence.

Background Cardiovascular diseases are the leading causes of mortality and morbidity in Western countries. The possible synergistic effect of poor adherence to a Mediterranean diet (MD) and other risk factors for acute myocardial infarction (AMI) such as hypertension, cholesterol, ever smoker, BMI> 25, diabetes, has not been deeply studied. Design Case-control study. Methods Patients with first AMI and controls from four tertiary referral Italian centers were screened for enrolment. Dietary information was collected through a questionnaire and a MD adherence score was calculated. Physical activity and smoking habits were also registered. The Synergy Index was calculated according to Rothman. Results 127 cases and 173 controls were enrolled. The analysis was conducted using a dichotomous variable for the MD score with values ≥7 representing good adherence. Multivariate analysis showed the following variables associated to AMI: ever smoker (OR = 2.08), diabetes (OR = 1.42), hypertension (OR = 2.08), hypercholesterolemia (OR = 2.47), BMI> 25 (OR = 1.99), while a protective effect emerged both in subjects scoring > 7 on the MD score (OR = 0.55) and in subjects resident of Southern Italy (OR = 0.38). A synergistic effect does exist between poor adherence to the MD and the following risk factors: hypertension, hypercholesterolemia, BMI >25, diabetes and being a resident in central and northern Italy. Conclusion Synergy between heart disease risk factors and MD underlines the need to enlarge the list of known modifiable cardiovascular risk factors to include and promote adherence to Mediterranean dietary habits.

Food insecurity is associated with HIV treatment non-adherence and poor health outcomes for people living with HIV/AIDS. Given the poor nutritional status common to people who drink alcohol, food insecurity may be particularly problematic for HIV positive individuals who drink alcohol. To examine food insecurity among HIV positive men and women who drink alcohol and its association with antiretroviral therapy (ART) adherence, health outcomes and health service utilization. Adults living with HIV (N = 183) in Atlanta, Georgia who reported alcohol use in the previous week and were receiving ART participated in a 12-month cohort. Participants were recruited from infectious disease clinics and social services to complete computerized interviews, monthly-unannounced pill counts to monitor ART adherence, and daily cell-phone delivered interactive-text assessments for alcohol use. Forty-three percent of participants experienced food insecurity during at least one month of the study period. Food insecurity was independently associated with suboptimal ART adherence and less suppressed HIV viral load over. Individuals who experienced food insecurity also had histories of more medical and psychiatric hospitalizations, and greater mental health problems. Food insecurity is prevalent among alcohol using people receiving ART and food insecurity is associated with treatment non-adherence, poor health outcomes, and increased medical and psychiatric hospitalizations.

Type D personality is associated with medication non-adherence. Both Type D personality and non-adherence are predictors of poor outcomes. Self-efficacy, which is modifiable, is also associated with medication adherence. To determine the relationships among Type D personality, self-efficacy, and medication adherence in 84 heart failure patients. Self-efficacy, Type D personality, medication adherence, demographic and clinical data were collected. Hierarchical linear regression was used. Type D patients were more likely to have lower self-efficacy (p = .023) and medication non-adherence (p = .027) than non-Type D patients. Low self-efficacy was associated with medication non-adherence (p < .001). Type D personality didn't predict medication adherence after entering self-efficacy in the model (p = .422), demonstrating mediation. Self-efficacy mediates the relationship between Type D personality and medication adherence. Developing and applying interventions to enhance self-efficacy may help to sever the link between Type D personality and poor outcomes. Copyright © 2015 Elsevier Inc. All rights reserved.

Improving Adherence to Treatment and Reducing Economic Costs of Hypertension: The Role of Olmesartan-Based Treatment.

PubMed

Costa, Francesco Vittorio

2017-09-01

Poor adherence to antihypertensive treatment is the single most important factor of unsatisfactory blood pressure (BP) control. This review focuses on therapy-related factors affecting adherence and suggests how to improve it with a wise choice of treatment schedule. Complex drug treatment schemes, poor tolerability and drug substitutions are frequent causes of poor adherence which, in turn, causes insufficient BP control, greater incidence of cardiovascular events and, finally, higher global health costs. The effects of prescribing generic drugs and of drug substitutions on adherence is also discussed. In terms of adherence, generic drugs do not seem to be better than branded drugs, unless patients have to bear very high "out of pocket" expenses to buy original drugs, suggesting no advantages in switching drug with the mere goal of reducing the cost of therapy. An important role in improving adherence (and thus cardiovascular events and health expenditure) is also played by the availability of fixed-dose combinations; among antihypertensive drugs, angiotensin receptor blockers (ARBs) are those associated with higher levels of adherence and persistence. Among ARBs, olmesartan stands out for a wide choice of effective fixed-dose combinations.

Background Ensuring an equal benefit across different patient groups is necessary while scaling up free-of-charge antiretroviral treatment (ART) services. This study aimed to measure the disparity in access, adherence, and outcomes of ART in Vietnam and the effects of socioeconomic status (SES) characteristics on the levels of inequality. Methods A cross-sectional study was conducted in 1133 PLWH in Vietnam. ART access, adherence, and treatment outcomes were self-reported using a structured questionnaire. Wealth-related inequality was calculated using a concentration index, and a decomposition analysis was used to determine the contribution of each SES variable to inequality in access, adherence, and outcomes of ART. Results Based on SES, minor inequality was found in ART access and adherence while there was considerable inequality in ART outcomes. Poor people were more likely to start treatment early, while rich people had better adherence and overall treatment outcomes. Decomposition revealed that occupation and education played important roles in inequality in ART access, adherence, and treatment outcomes Conclusion The findings suggested that health services should be integrated into the ART regimen. Furthermore, occupational orientation and training courses should be provided to reduce inequality in ART access, adherence, and treatment outcomes. PMID:28005937

Poor diet quality in childhood and adolescence is associated with adverse health outcomes throughout life, yet the dietary habits of American children and how they change across childhood and adolescence are unknown. This study sought to describe diet quality among children and adolescents by assessing adherence to the 2010 Dietary Guidelines for Americans (DGA) and to determine whether any differences in adherence occurred across childhood. We employed a cross-sectional design using data from the National Health and Nutrition Examination Survey (NHANES). Of 9,280 children aged 4 to 18 years who participated in NHANES from 2005 to 2010, those with insufficient data on dietary recall (n=852) or who were pregnant or lactating during the time of interview (n=38) were excluded from the final study sample (n=8,390). We measured adherence to the DGA using the Healthy Eating Index 2010 (HEI-2010) and stratified participants into three age groups (4 to 8, 9 to 13, and 14 to 18 years of age). We analyzed each of 12 HEI-2010 components and total HEI-2010 score. The youngest children had the highest overall diet quality due to significantly greater scores for total fruit, whole fruit, dairy, and whole grains. These children also had the highest scores for sodium, refined grains, and empty calories. Total HEI-2010 scores ranged from 43.59 to 52.11 out of 100, much lower than the minimum score of 80 that is thought to indicate a diet associated with good health. Overall, children and adolescents are failing to meet the DGA and may be at an increased risk of chronic diseases throughout life. By analyzing which food groups show differences between age groups, we provide data that can inform the development of dietary interventions to promote specific food groups targeting specific ages and improve diet quality among children and adolescents.

Medication adherence in glaucoma: approaches for optimizing patient compliance.

PubMed

Tsai, James C

2006-04-01

To summarize recent literature regarding medication adherence with a focus on the complexities inherent in glaucoma management. Adherence to medications can be enhanced by undertaking the following strategies: enhanced patient education; improved dosing schedules; increased accessibility to healthcare (including longer hours, evening hours, and shorter wait times), and improved provider-patient relationships (e.g. increased trust). Patients may be less likely to forgo medication use due to cost pressures if the physician trust level is high. Recent studies suggest a role for baseline screening for adherence predictors and focused interventions in addressing modifiable risk factors for poor adherence (such as depression, stress, and lower education). Many factors are associated with the lack of medication adherence in patients. The solution is likely to be multi-dimensional and employ combination strategy (must be individualized for the patient). Educational interventions involving patients, family members, or both can be effective in improving adherence.

A higher adherence to Mediterranean diet is considered as a protective factor against the large number of deaths attributable to the main chronic degenerative diseases in developed countries. Self-rated health is established as a good indicator of population health status and as a predictor of mortality. Studies exploring the relationship between the adherence to Mediterranean diet and self-rated health are scarce, especially, in young adults. Our aim was to explore the factors related, specially the adherence to a priori-defined Mediterranean diet with self-rated health in a cohort of Spanish university students. We analyzed data from 1110 participants of Spanish DiSA-UMH (Dieta, Salud y Antropometría en universitarios de la Universidad Miguel Hernández) study. Diet was assessed using a validated food frequency questionnaire and the adherence to Mediterranean diet was calculated using the relative Mediterranean Diet Score (rMED; score range: 0-18) according to the consumption of 9 dietary components. Self-rated health was gathered from the question: "In general, how do you consider your health to be? (Excellent, good, fair, poor, very poor). Information on sociodemographic and lifestyle characteristics was also collected. Multinomial logistic regression (using relative risk ratio, RRR) was used to analyze the association between the adherence to Mediterranean diet (low rMED: 0-6 points; medium: 7-10 points; high: 11-18 points) and self-rated health (Excellent (reference), good and fair/ poor/very poor). A low, medium or high adherence to Mediterranean diet conformed to 26.8%, 58.7% and 14.4% of participants, which of them reported an excellent (23.1%), good (65.1%) and fair/poor or very poor health, respectively. In multivariate analysis, a lower adherence to Mediterranean diet was significantly (p. Copyright AULA MEDICA EDICIONES 2014. Published by AULA MEDICA. All rights reserved.

2015-01-01

Background Cystic fibrosis (CF) health care professionals recognize the need to motivate people with CF to adhere to nebulizer treatments, yet little is known about how best to achieve this. We aimed to produce motivational posters to support nebulizer adherence by using social marketing involving people with CF in the development of those posters. Methods The Sheffield CF multidisciplinary team produced preliminary ideas that were elaborated upon with semi-structured interviews among people with CF to explore barriers and facilitators to the use of nebulized therapy. Initial themes and poster designs were refined using an online focus group to finalize the poster designs. Results People with CF preferred aspirational posters describing what could be achieved through adherence in contrast to posters that highlighted the adverse consequences of nonadherence. A total of 14 posters were produced through this process. Conclusion People with CF can be engaged to develop promotional material to support adherence, providing a unique perspective differing from that of the CF multidisciplinary team. Further research is needed to evaluate the effectiveness of these posters to support nebulizer adherence. PMID:26346635

Research on antipsychotic medication non-adherence in first-episode psychosis patients tends to examine non-adherence behaviors and attitudes together. Nonetheless, attitudes do not always directly translate into behaviors. We examined the baseline predictors for antipsychotics non-adherence behaviors and attitudes separately in a first-episode psychosis cohort. We also included cognitive impairments as one of the predictor variables as this domain is rarely explored in adherence studies. Participants were 313 adult-onset psychosis patients recruited from the Jockey Club Early Psychosis project in Hong Kong. Demographic, premorbid, clinical, and cognitive characteristics were first assessed at baseline. Six months later, participants completed a 14-item Medication Compliance Questionnaire, which was a modified and Cantonese-translated version of the Medication Adherence Rating Scale that includes items pertaining to both adherence behaviors and attitudes. Rates of poor adherence behaviors and negative adherence attitudes were 17.6% and 27.8%, respectively. Determinants of poor adherence behavior included more severe positive symptoms, hospitalization at onset of illness, and poorer engagement in extended social network. As for negative adherence attitude, determinants included more severe general psychopathology, poorer insight, more psychic medication side-effects, and poorer performance on backward digit span test and WAIS-R information test. The risk factors for non-adherence behaviors and attitudes are different and they should all be taken into careful consideration while formulating appropriate intervention programs to tackle the adherence problem in adult onset psychosis.

Medication adherence is critical to the success of antiretroviral therapies for children and youth with perinatally acquired HIV. Factors that influence successful transition of medication responsibility from caregivers to youth are poorly understood. The purpose of this study was to evaluate the relationship of medication adherence with demographic, cognitive, academic, and behavioral characteristics. Randomly selected youth, N = 151, aged 8 to 18 years, completed cognitive and academic measures, and they and their caregivers completed questionnaires assessing behavior and emotional well-being. An announced pill count and questionnaires completed by youth and their caregivers were used to evaluate adherence. Of 151 participants, 100 completed all adherence measures. Adherence rates varied by assessment method. Nonadherence (<90%) by pill count was associated with older child age, greater youth responsibility for medications, and other demographic and medication regimen variables. Verbal impairment predicted better self-reported adherence and reading problems predicted better self- and caregiver-reported adherence. Youth-reported locus of control was associated with pill count nonadherence, and poor relationships with parents were associated with youth-reported nonadherence. Consideration of youth cognitive or academic status may be helpful in evaluating medication adherence in patients with perinatally acquired HIV infection, particularly when using self- or caregiver reports to assess adherence. Vigilance for adherence problems is indicated when youth are older, responsible for medications, report poor caregiver relationships, and/or sense a lack of control over their lives.

Summary Poor adherence to continuous positive airway pressure (CPAP) treatment is associated with substantial health care costs, morbidity and mortality, and has been a leading obstacle in the effective management of obstructive sleep apnea (OSA). Successful interventions to improve CPAP adherence may ultimately include a variety of components. For patients living with spouses (refers to all domestic partners), the spouse will likely be an integral component to any successful intervention. Developing understanding of the role of spouses in adherence to CPAP has been identified to be a critical research need. This review expands the investigation of CPAP adherence to a broader context, from an exclusive focus on individual patients to a dyadic perspective encompassing both patients and their spouses. A conceptual framework based on social support and social control theories is proposed to understand spousal involvement in CPAP adherence. Methodologies for future investigations are discussed, along with implications for developing interventions that engage both patients and their spouses to improve CPAP use. PMID:24906222

The aim of this study was to estimate the level of adherence to the Mediterranean diet in a group of Italian high school students, in relation to their lifestyles and social and family contexts, and to compare the nutrition habits of the sample with other similar groups. The KIDMED index and an ad hoc questionnaire were administered to 1127 students (mean age 16.8 ± 1.6 y) in the province of Florence. Any significant associations between the level of adherence to the Mediterranean diet and the aforementioned variables were assessed by the χ(2) test and by logistic regression analysis. The adherence to the Mediterranean diet was good in 16.5%, average in 60.5%, and poor in 23% of the students. The students attending technical high schools, those who played sports less than "almost every day", those who spent >3 h/d in sedentary activities, those who defined their school performance as worse than "more than sufficient," and those who referred to use of a car/moped as the most frequent mode of transportation, had significantly higher odds of poor rather than average or good adherence to Mediterranean diet. Moreover, being normal weight or overweight/obese, and referring to health workers as source of information on diet, seem to be protective factors against poor adherence to Mediterranean diet. Our sample presents a departure from the Mediterranean dietary pattern. It is certainly necessary to implement public health policies targeting teenagers to promote healthier lifestyle choices; the nutritional patterns of the Mediterranean diet should be among these choices.

It's all a matter of necessity and concern: A structural equation model of adherence to antihypertensive medication.

PubMed

Wilhelm, Marcel; Rief, Winfried; Doering, Bettina K

2018-03-01

Hypertension is often treated pharmacologically, yet adherence is poor. Beliefs about antihypertensive medicine, i.e., the necessity-concern framework (NCF), are valuable for explaining adherence. Therefore, a model structure is transferred from hypercholesterolemia to hypertension, assuming a mediating role of the NCF. Patients with hypertension (n=273) were surveyed online about demographics, health- and treatment-related factors, control beliefs, necessity and concern beliefs about their medication, and adherence. The data were analyzed using structural equation modeling (SEM). Necessity was positively (β=0.26, p=0.009) and concern was negatively (β=-0.51, p=0.020) associated with adherence. The NCF mediated the influence of background variables on adherence. Necessity was associated with comorbidity (β=-0.36, p<0.001), treatment time (β=0.19, p=0.004), emotionally supportive doctor-patient communication (β=0.12, p=0.045), side effects (β=0.16, p=0.013), personal control (β=-0.13, p=0.022), and treatment control (β=0.29, p<0.001). Concern was associated with side effects (β=0.38, p<0.001) and beliefs about medicine in general being harmful (β=0.61, p<0.001). The model fit was acceptable (RMSEA=0.61). The transferred adherence model with the necessity-concern framework as a mediating factor was confirmed in hypertension, explaining more variance than previous approaches (23%). A personalized, emotionally supportive doctor-patient communication could be key to addressing beliefs about medicine and therefore to increasing adherence. Copyright © 2017 Elsevier B.V.

Heart failure (HF) is a chronic disease characterised by poor quality of life, recurrent hospitalisation and high mortality. Adherence of patient to treatment suggested by the experts has been proven a significant deterrent of the above-mentioned serious consequences. However, the non-adherence rates are significantly high; a fact that highlights the importance of predicting the adherence of the patient and enabling experts to adjust accordingly patient monitoring and management. The aim of this work is to predict the adherence of patients with HF, through the application of machine learning techniques. Specifically, it aims to classify a patient not only as medication adherent or not, but also as adherent or not in terms of medication, nutrition and physical activity (global adherent). Two classification problems are addressed: (i) if the patient is global adherent or not and (ii) if the patient is medication adherent or not. About 11 classification algorithms are employed and combined with feature selection and resampling techniques. The classifiers are evaluated on a dataset of 90 patients. The patients are characterised as medication and global adherent, based on clinician estimation. The highest detection accuracy is 82 and 91% for the first and the second classification problem, respectively.

Knowledge, adherence and control among patients with hypertension attending a peri-urban primary health care clinic, KwaZulu-Natal

PubMed Central

2017-01-01

Background Despite hypertension being a common condition among patients attending primary health care (PHC) clinics, blood pressure (BP) control is often poor. Greater insight into patient-related factors that influence the control of hypertension will assist in the development of an intervention to address the issues identified. Aim The aim of the study was to assess patient-related variables associated with hypertension control among patients attending a peri-urban PHC clinic. Setting The setting for this study was a peri-urban PHC clinic in KwaZulu-Natal. Method This was an observational, descriptive and cross-sectional study with 348 patients selected over a 1-month period. A validated questionnaire was used to collect data on patients’ hypertension knowledge and self-reported adherence, and BP recordings from their medical record were recorded to ascertain control. Results Of the 348 participants, only 49% had good BP control and 44% (152/348) had concurrent diabetes mellitus. The majority of patients had moderate levels of knowledge on hypertension and exhibited moderate adherence. There was a significant relationship between knowledge and reported adherence, between reported adherence and control, but not between reported knowledge and control. Conclusion Despite over 90% of the study population having moderate knowledge, and 62% with moderate reported adherence, BP was well controlled in only less than 50% of the study population. These findings suggest a need to emphasise adherence and explore new ways of approaching adherence. PMID:29113443

There are serious outcomes to nonadherence to psychotropic medications in children and adolescents, including poor school performance, prolonged duration of illness, increased psychopathology, poor interpersonal relationships, increased psychiatric episodes, and suicide attempts. Medication treatment has demonstrated improved psychiatric functioning and a 50% reduction in suicidal behavior. more than 50% of youth with mental health problems are nonadherent with psychiatric medications. A review of literature examining motivational interviewing (MI) for the problem of treatment adherence in children and adolescents is discussed. MI has great potential to improve psychiatric medication adherence in adolescents. An example of how to implement MI with youth is provided.

Pediatric transplant (txp) teams note high rates of non-adherence and risky behaviors linked to morbidity and mortality among adolescent and young adult recipients. Clinicians and parents alike report symptoms of social immaturity and failure to appreciate consequences of risky behavior; relationships between the two have not been studied in this population. This two-phase mixed method study examined adherence, high-risk behaviors, and maturity in a sample of 27 heart recipients, aged 15-31, who underwent transplantation in childhood or adolescence at Children's Hospital of Pittsburgh. All subjects completed a projective ego development measure and a questionnaire about adherence to the post-txp regimen. Nine recipients, purposely selected for good or poor adherence according to criteria determined by the transplant team and matched on age, participated in phase 2 qualitative interviews and mood assessments. Sixty-three percent of the phase 1 sample missed medications, 67% missed appointments, 11% smoked, 37% had difficulty with diet, 89% exercised infrequently, 33% had tattoos, 26% had more than two body piercings, and 11% used street drugs. Six themes and a core construct of maturity were identified with qualitative methodology. Poor adherers were less mature on every theme and consistently scored at a less mature level on the projective measure of ego development. Chronological age was not related to the level of maturity in qualitative or projective data. Most interview subjects reported high levels of anxiety, and two reported clinically significant levels of depression and anger; mood was not related to adherence. Non-adherence and high-risk behaviors are prevalent among adolescent and young adult heart recipients. Level of maturity appears to be associated with ability to adhere to the treatment regimen and avoid high-risk behaviors.

Background Low adherence to pharmacological treatments is one of the factors associated with poor blood pressure control. Questionnaires are an indirect measurement method that is both economic and easy to use. However, questionnaires should meet specific criteria, to minimize error and ensure reproducibility of results. Numerous studies have been conducted to design questionnaires that quantify adherence to pharmacological antihypertensive treatments. Nevertheless, it is unknown whether questionnaires fulfil the minimum requirements of validity and reliability. The aim of this study was to compile validated questionnaires measuring adherence to pharmacological antihypertensive treatments that had at least one measure of validity and one measure of reliability. Methods A literature search was undertaken in PubMed, the Excerpta Medica Database (EMBASE), and the Latin American and Caribbean Health Sciences Literature database (Literatura Latino-Americana e do Caribe em Ciências da Saúde [LILACS]). References from included articles were hand-searched. The included papers were all that were published in English, French, Portuguese, and Spanish from the beginning of the database’s indexing until July 8, 2013, where a validation of a questionnaire (at least one demonstration of the validity and at least one of reliability) was performed to measure adherence to antihypertensive pharmacological treatments. Results A total of 234 potential papers were identified in the electronic database search; of these, 12 met the eligibility criteria. Within these 12 papers, six questionnaires were validated: the Morisky–Green–Levine; Brief Medication Questionnaire; Hill-Bone Compliance to High Blood Pressure Therapy Scale; Morisky Medication Adherence Scale; Treatment Adherence Questionnaire for Patients with Hypertension (TAQPH); and Martín–Bayarre–Grau. Questionnaire length ranged from four to 28 items. Internal consistency, assessed by Cronbach’s α, varied from 0

To analyse any association between general beliefs about medicines and self-reported adherence among pharmacy clients. Further, to examine general beliefs about medicines by background variables. The data were collected by questionnaires including the general section of the Beliefs about Medicines Questionnaire (BMQ), the self-reporting Medication Adherence Report Scale (MARS) and the following background variables: gender, age, education, country of birth and medicine use. The General BMQ measures beliefs about medicines as something harmful (General-Harm), beneficial (General-Benefit) and beliefs about how doctors prescribe medicines (General-Overuse). Of the 324 participating pharmacy clients, 54% were considered non-adherent. An association was found between General-Harm and adherence. Adherent behaviour and higher level of education were associated respectively with more beneficial and less harmful beliefs about medicines. Those born in the Nordic countries regarded medicines as more beneficial. Current users of herbal medicines and non-users of medicines were more likely to believe that doctors overprescribed medicines. General-Harm was associated with adherence to medication among Swedish pharmacy clients. Country of birth, education and medicine use influenced beliefs about medicines. Increased awareness of the patient's beliefs about medicines is needed among healthcare providers. We should encourage patients to express their views about medicines in order to optimize and personalize the information process. This can stimulate concordance and adherence to medication.

Impact of Medication Adherence on Mortality and Cardiovascular Morbidity: Protocol for a Population-Based Cohort Study

PubMed Central

2018-01-01

Background Cardiovascular disease (CVD) is a group of disorders of the heart and blood vessels, such as coronary heart disease (CHD), cerebrovascular disease, and peripheral artery disease. CVD is the leading threat to global health, whether measured by mortality, morbidity, or economic cost. Long-term administration of aspirin, statins, beta-blockers, and angiotensin-converting enzyme inhibitors or angiotensin-receptor blockers improves survival in patients with stablished coronary heart disease. Nevertheless, adherence to prescribed medication is poor for long-term drug treatment. Objective We aim to assess the relationship between adherences to the four pharmacological groups recommended for secondary prevention and the clinical outcomes of cardiovascular morbidity and mortality in patients with established CHD according to the level of adherence to these drugs in a population of incident cases of acute coronary syndrome (ACS). Methods Population-based cohort study of patients with a first episode of ACS during 2006-2015 in the Information System for Research in Primary Care (SIDIAP) database. We will estimate adherence to these drugs. The primary endpoint is a composite of all-cause mortality, ACS, and ischaemic stroke. Bivariate analyses will be performed estimating odds ratios for categorical variables and mean differences for continuous variables. Hazard ratios for adherences will be calculated for outcome events using Cox proportional hazard regression models, and proportionality of hazards assumption will be tested. Results We expect to estimate adherence to all four study treatments, the incidence of MACE, and to analyze if this incidence is associated with the level of drug adherence. Conclusions We expect to find that adherent patients have a lower risk of the primary endpoints compared with nonadherent patients. Trial Registration This study protocol was classified as EPA-OD by the AEMPS (IJG-EST-2017-01-2017-01, 07/04/2017) and registered in the EU

Background It is not well understood how sedentary women who wish to engage in regular exercise adhere to interventions during pregnancy and what factors may influence adherence over time. Objective To examine longitudinal patterns of pregnant women’s adherence to exercise. Methods Exploratory secondary data analyses were carried out with 124 previously sedentary pregnant women (ages 31 ± 5 years; 85% non-Hispanic White) from a randomized controlled trial. Daily exercise logs (n = 92) from 18 through 35 weeks of gestation were explored using linear regression, functional data, and principal component analyses. Results Adherence decreased as gestation week increased (p < .001); the top adherers maintained levels of adherence, and the bottom adherers decreased levels of adherence; and adherence pattern was influenced by types of exercise throughout the study period. Discussion Exercise behavior patterns were explored in a randomized controlled trial study, using chronometric data on exercise attendance. A new analytic approach revealed that sedentary pregnant women may adopt exercise habits differently from other populations. PMID:20585224

Objectives The purpose of this study was to examine whether mothers’ musical background has an effect on their own and their children’s sedentary behavior (SB) and physical activity (PA). The aim was also to assess children’s and their mothers’ exercise adherence when using movement-to-music video program. Design Sub-group analysis of an intervention group in a randomized controlled trial (ISRCTN33885819). Method Seventy-one mother-child-pairs were divided into two categories based on mothers’ musical background. Each pair performed 8 weeks exercise intervention using movement-to-music video program. SB and PA were assessed objectively by accelerometer, and exercise activity, fidelity, and enjoyment were assessed via exercise diaries and questionnaires. Logistic regression model was used to analyze associations in the main outcomes between the groups. Results Those children whose mothers had musical background (MB) had greater probability to increase their light PA during the intervention, but not moderate-to-vigorous PA compared to those children whose mothers did not have musical background (NMB). SB increased in both groups. Mothers in the NMB group had greater probability to increase their light and moderate-to-vigorous PA and decrease their SB than mothers in the MB group. However, exercise adherence decreased considerably in all groups. Completeness, fidelity, and enjoyment were higher among the NMB group compared to the MB group. Conclusions The present results showed that mothers without musical background were more interested in movement-to-music exercises, as well as their children. For further studies it would be important to evaluate an effect of children’s own music-based activities on their SB and PA. PMID:29668726

2017-11-01

Drug-resistant tuberculosis (DR-TB) treatment is expensive, lengthy, and can cause severe side effects. Patients face socio-economic, psychosocial, and systemic barriers to adherence; poor adherence results in poor treatment outcomes. To estimate the effects of the components of the information-motivation-behavioral skills model on DR-TB treatment adherence. We recruited 326 adults receiving DR-TB treatment and 86 of their health care service providers from 40 health centers in Lima, Peru. The main outcome was adherence (i.e., the proportion of prescribed doses taken by a patient). Exposure measures were adherence information, motivation, and behavioral skills; loss to follow-up during previous TB treatment(s); providers' work engagement; and patient-perceived support from his/her social network. Structural equation modeling revealed that adherence information and motivation had positive effects on adherence, but only if mediated through behavioral skills (β = 0.02, P < 0.01 and β = 0.07, P < 0.001, respectively). Behavioral skills had a direct positive effect on adherence (β = 0.27, P < 0.001). Loss to follow-up during previous treatment had a direct negative effect, providers' work engagement had a direct positive effect, and perceived support had indirect positive effects on adherence. The model's overall R2 was 0.76. The components of the information-motivation-behavioral skills model were associated with adherence and could be used to design, monitor, and evaluate interventions targeting adherence to DR-TB treatment.

Background Clinical guidelines are considered important instruments to improve quality in health care. In physiotherapy, insight in adherence to guidelines is limited. Knowledge of adherence is important to identify barriers and to enhance implementation. Purpose of this study is to investigate the ability to adherence to recommendations of the guideline Acute ankle injury, and to identify patient characteristics that determine adherence to the guideline. Methods Twenty-two physiotherapists collected data of 174 patients in a prospective cohort study, in which the course of treatment was systematically registered. Indicators were used to investigate adherence to recommendations. Patient characteristics were used to identify prognostic factors that may determine adherence to the guideline. Correlation between patient characteristics and adherence to outcome-indicators (treatment sessions, functioning of patient, accomplished goals) was calculated using univariate logistic regression. To calculate explained variance of combined patient characteristics, multivariate analysis was performed. Results Adherence to individual recommendations varied from 71% to 100%. In 99 patients (57%) the physiotherapists showed adherence to all indicators. Adherence to preset maximum of six treatment sessions for patients with severe ankle injury was 81% (132 patients). The odds to receive more than six sessions were statistically significant for three patient characteristics: females (OR:3.89; 95%CI: 1.41–10.72), recurrent sprain (OR: 6.90; 95%CI: 2.34 – 20.37), co-morbidity (OR: 25.92; 95% CI: 6.79 – 98.93). All factors together explained 40% of the variance. Inclusion of physiotherapist characteristics in the regression model showed that work-experience reduced the odds to receive more than six sessions (OR: 0.2; 95%CI: 0.06 – 0.77), and increased explained variance to 45%. Conclusion Adherence to the clinical guideline Acute ankle sprain showed that the guideline is

Older minority groups are more likely to have poor AED adherence. We describe adherence to antiepileptic drugs (AEDs) among older Americans with epilepsy. In retrospective analyses of 2008-2010 Medicare claims for a 5% random sample of beneficiaries augmented by minority representation, epilepsy cases in 2009 were those with ≥1 claim with ICD-9345.x or ≥2 with 780.3x, and ≥1 AED. New-onset cases had no such claims or AEDs in the year before the 2009 index event. We calculated the Proportion of Days Covered (PDC) (days with ≥1 AED over total follow-up days) and used logistic regression to estimate associations of non-adherence (PDC <0.8) with minority group adjusting for covariates. Of 36,912 epilepsy cases (19.2% White, 62.5% African American (AA), 11.3% Hispanic, 5.0% Asian and 2% American Indian/Alaskan Native), 31.8% were non-adherent (range: 24.1% Whites to 34.3% AAs). Of 3706 new-onset cases, 37% were non-adherent (range: 28.7% Whites to 40.5% AAs). In adjusted analyses, associations with minority group were significant among prevalent cases, and for AA and Asians vs. Whites among new cases. Among other findings, beneficiaries from high-poverty ZIP codes were more likely to be non-adherent than their counterparts, and those in cost-sharing drug benefit phases were less likely to be non-adherent than those in deductible phases. About a third of older adults with epilepsy have poor AED adherence; minorities are more likely than Whites. Investigations of reasons for non-adherence, and interventions to promote adherence, are needed with particular attention to the effect of cost-sharing and poverty. Copyright © 2016 Elsevier Inc.

Men with congenital hypogonadotrophic hypogonadism (CHH) typically require lifelong hormonal therapy, and discontinuing treatment can have negative health consequences. Little is known about adherence to treatment or the psychosocial impact of CHH. A sequential, multiple methods approach was used. A quantitative online survey assessed adherence to treatment, depressive symptoms and illness perceptions. Subsequently, qualitative focus groups explored patient-reported factors for adherence. Adult men with CHH on at least 1 year of treatment were recruited internationally. Adherence (Morisky medication adherence scale), depressive symptoms (Zung self-rating depression scale) and patient perception of CHH (revised illness perception questionnaire) were assessed in an online survey, and comparisons were made to reference groups. Patient focus group discussions were conducted and thematic analysis was employed to identify patient-reported factors for adherence. In total, 101 men on long-term treatment were included (mean age 37 ± 11 years). Forty three percent (43/101) exhibited low medication adherence and a significantly elevated prevalence of mild, moderate or severe depressive symptoms (27%, 17%, 20%, respectively, all P < 0·001 vs reference population). Patients reported negative illness perceptions and significant psychosocial consequences. Focus group discussions (n = 3, 26 total patients) identified patient-, health professional- and healthcare system-related barriers as targets for improving adherence. Congenital hypogonadotrophic hypogonadism men are challenged to adhere to long-term treatment. Poor adherence may contribute to adverse effects on bone, sexual and psychological health. The psychosocial morbidity of CHH is significant and appears to be underappreciated by healthcare providers. © 2016 John Wiley & Sons Ltd.

Proton pump inhibitors (PPIs) play a well-documented role as a gastroprotective agent among NSAID users at an increased risk of peptic ulcer and bleeding. Observational studies have, however, suggested that the clinical efficacy of PPI therapy may be reduced because of poor adherence. To study the association between adherence to concomitant PPI in current NSAID users and the risk of peptic ulcer and bleeding. Case-control study linking nationwide data from the Swedish Patient Registry with the Swedish Drug Prescription Database. The study population included patients admitted for a first-time peptic ulcer or bleeding and who were incident users of NSAID. Each case was matched on age, sex, NSAID duration, and calendar month with five controls. PPI adherence was calculated as the proportion of NSAID days being covered by PPI therapy. Matched and adjusted odds ratios (ORs) with 95% confidence intervals (CIs) were calculated using conditional logistic regression. A total of 3649 cases were identified. Patients with poor adherence (<20% PPI coverage) had a significantly increased risk of upper gastrointestinal complications (OR=1.88, 95% CI 1.22-2.88) compared with fully adherent patients (≥80% PPI coverage). As a continuous variable, the risk of an event increased with 6% points for every 10% decrease in PPI adherence (OR=1.06, 95% CI 1.03-1.10). The gastroprotective effect of PPI in NSAID users is highly dependent on adherence, with about twice the risk in patients with poor adherence. Efforts to increase adherence should be an integrated part of clinical practice.

A substantial proportion of people with mental health conditions do not adhere to prescribed pharmacological treatments. Poor adherence is probably one of the most critical elements contributing to relapse in people with schizophrenia and other severe mental disorders. In order to tackle this global issue, in November 2017 the Food and Drug Administration approved a tablet formulation of the atypical antipsychotic aripiprazole embedded with a novel digital adherence-assessment device. In this commentary, we critically appraised the potential beneficial and harmful consequences of this new digital formulation of aripiprazole, and we highlighted expected implications for clinical practice.

Poor patients' adherence to intake of prescribed medication has been identified as a serious problem in the treatment of chronically ill patients. Technical solutions are needed to measure and - if necessary - to increase the patients' adherence. A telemonitoring solution was developed to record a patient's medication intake based on smart blisters and mobile phones with NFC functionality. The components allowed recording of drug type, timestamp, and dosage of pills taken. The system's usability and technical feasibility was evaluated in the course of an application study. Over a period of 13 months 59 patients suffering from diabetes were monitored. 1,760 blisters were handed out to these patients and 14,843 takeout events were recorded and transmitted via mobile phone. Results indicate the feasibility of this concept to monitor adherence. Although the system still needs to be optimized for routine use it shows the potential for targeting the problem of poor patient adherence by NFC enabled devices.

Poor adherence to long-term antipsychotic injectable (LAI) medication in patients with psychotic disorders is associated with a range of negative outcomes. No psychosocial intervention has been found to be consistently effective in improving adherence. To test whether or not offering financial incentives is effective and cost-effective in improving adherence and to explore patient and clinician experiences with such incentives. A cluster randomised controlled trial with economic and nested qualitative evaluation. The intervention period lasted for 12 months with 24 months' follow-up. The unit of randomisation was mental health teams in the community. Community teams in secondary mental health care. Patients with a diagnosis of schizophrenia, schizoaffective psychosis or bipolar illness, receiving ≤ 75% of their prescribed LAI medication. In total, 73 teams with 141 patients (intervention n = 78 and control n = 63) were included. Participants in the intervention group received £15 for each LAI medication. Patients in the control group received treatment as usual. adherence to LAI medication (the percentage of received out of those prescribed). percentage of patients with at least 95% adherence; clinical global improvement; subjective quality of life; satisfaction with medication; hospitalisation; adverse events; and costs. Qualitative evaluation: semistructured interviews with patients in the intervention group and their clinicians. outcome data were available for 131 patients. Baseline adherence was 69% in the intervention group and 67% in the control group. During the intervention period, adherence was significantly higher in the intervention group than in the control group (85% vs. 71%) [adjusted mean difference 11.5%, 95% confidence interval (CI) 3.9% to 19.0%; p = 0.003]. Secondary outcome: patients in the intervention group showed statistically significant improvement in adherence of at least 95% (adjusted odds ratio 8.21, 95% CI 2.00 to 33

Background Little is known about the functional health literacy (FHL) associated with medication adherence in elderly patients. The aim of this study was to examine the FHL among older adults and identify influencing factors that can predict medication adherence. Methods This was a cross-sectional survey. Participants (n=160) aged 65 years and older were selected from outpatient clinics of 3 tertiary care hospitals, 6 community pharmacies, and 2 senior centers between November 1 and 30, 2014. The participants’ FHL was measured using the Korean Functional Health Literacy Test, which consists of 15 items including 8 numeracy and 7 reading comprehension items. Medication adherence was measured by the Adherence to Refills and Medication Scale. Descriptive statistics, chi-square or Fisher’s exact test, and multiple regression analyses were used to analyze the data. Results The mean score of the total FHL was 7.72±3.51 (range 0–15). The percentage of the total number of correct answers for the reading comprehension subtest and numeracy subtest were 48.1% and 54.4%, respectively. Among 160 participants, 52.5% showed low adherence to medication. The factors affecting medication adherence included the patient’s degree of satisfaction with the service (β=−0.215, P=0.022), sufficient explanation of medication counseling (β=−0.335, P=0.000), education level (β=−0.153, P=0.045), health-related problems (β=−0.239, P=0.004), and dosing frequency (β=0.189, P=0.018). Conclusion In this study, we found medication adherence of elderly patients was associated with education level, health-related problems, dosing frequency, satisfaction with patient counseling, and explanation of medication, but no association was found with FHL. Pharmacists should consider elderly patients’ individual characteristics such as educational background and specific patient-related health problems, provide sufficient information and explanation of medication, and ensure patient

Objective To review and critically evaluate the extant research literature pertaining to adherence in youth and adults with headache and to provide recommendations for future research. Background This article provides the first systematic review of pediatric headache adherence and updates a previous review of treatment adherence in adults with headache. Design Systematic review of empirical literature. Methods A literature search with no date restriction was conducted using PubMed and PsycINFO electronic databases and bibliographies of relevant articles. Results Adherence rates in adults with headache range considerably from 25% to 94% across treatment, assessment method, and definition of adherence utilized. Methods to assess adherence included retrospective prescription claims data, paper or electronic diaries, follow-up appointment attendance, written and verbal self-report of general adherence, verbal self-report of adherence over a specific amount of time via in person interview or telephone, validated adherence measures, adherence questionnaires without validation, and counselor ratings of homework. Each methodology and assessment tool demonstrated strengths and weaknesses. No studies have systematically examined medication adherence in children with headache, and the few available studies examining adherence to behavioral treatment have documented adherence rates ranging from 52% to 86%. Conclusions Adherence research in adults with headache is growing, but studies demonstrate a number of methodological shortcomings. Adherence research in children with headache, and adherence intervention research in both adults and children, is scant. Future research should use objective measures of adherence, consider over-the-counter medications and medication overuse, examine demographic, psychological, and behavioral correlates of adherence, assess adherence to botulinum toxin type A, and examine the efficacy of adherence interventions in individuals with headache.

Increased availability and accessibility of antiretroviral therapy (ART) has improved the length and quality of life amongst people living with HIV/AIDS. This has changed the landscape for care from episodic to long-term care that requires more monitoring of adherence. This has led to increased demand on human resources, a major problem for most ART programs. This paper presents experiences and perspectives of providers in ART facilities, exploring the organizational factors affecting their capacity to monitor adherence to ARVs. From an earlier survey to test adherence indicators and rank facilities as good, medium or poor adherence performances, six facilities were randomly selected, two from each rank. Observations on facility set-up, provider-patient interactions and key informant interviews were carried out. The strengths, weaknesses, opportunities and threats identified by health workers as facilitators or barriers to their capacity to monitor adherence to ARVs were explored during group discussions. Findings show that the performance levels of the facilities were characterized by four different organizational ART programs operating in Uganda, with apparent lack of integration and coordination at the facilities. Of the six facilities studied, the two high adherence performing facilities were Non-Governmental Organization (NGO) programs, while facilities with dual organizational programs (Governmental/NGO) performed poorly. Working conditions, record keeping and the duality of programs underscored the providers' capacity to monitor adherence. Overall 70% of the observed provider-patient interactions were conducted in environments that ensured privacy of the patient. The mean performance for record keeping was 79% and 50% in the high and low performing facilities respectively. Providers often found it difficult to monitor adherence due to the conflicting demands from the different organizational ART programs. Organizational duality at facilities is a major

Psychosocial influencers and mediators of treatment adherence in haemodialysis patients.

This article is a report of the development and testing of the hypothetical model that illustrates relationships between treatment adherence and its psychosocial influencing factors and to elucidate the direct and indirect (mediating) effects of factors on treatment adherence. Poor adherence has been consistently reported in haemodialysis patients. Much research has showed various influencing factors of adherence, but these studies have failed to identify consistent influencing factors. This study was performed using a non-experimental, cross-sectional design. The study subjects were 150 end-stage renal failure patients on haemodialysis at a university hospital located in Incheon, South Korea. Data were collected over 10 months (June 2010-April 2011). The hypothetical model provided a good fit with data. Haemodialysis-related knowledge, perceived barrier to adherence, self-efficacy on adherence, and healthcare provider support had significant effects on adherence. Self-efficacy was found to mediate barrier-adherence and family support-adherence relationships. Self-efficacy in combination with barrier, family support, and healthcare provider support was found to mediate the depression-adherence relationship. Strategies aimed at the development of successful adherence interventions should focus on reducing perceived barriers and enhancing self-efficacy and knowledge. It can be suggested that efforts to improve the healthcare provider-patient relationship would enhance adherence. In depressive patients, strategies that promote self-efficacy and the support of family or healthcare providers could diminish the negative impact of depression on adherence. © 2013 Blackwell Publishing Ltd.

Mobile Applications to Improve Medication Adherence.

Haase, Jamie; Farris, Karen B; Dorsch, Michael P

2017-02-01

Background and Introduction: Mobile applications are useful tools to improve medication adherence. As developers continue to improve the features of existing mobile applications, pharmacists should be aware of the current features that are available to patients. There are limited studies available that discuss which applications have the most desirable features. The aim of this study was to compare available mobile applications and identify ideal application features used to improve medication adherence. As of September 5, 2014, the search terms "medication adherence" and "medication reminder" generated a total of 225 hits. Ideal application features were used to create an Application Score Card to identify applications with the highest number of ideal features. We identified 30 applications that were written in English, medication related, last updated in 2014, and did not meet any exclusion criteria. The top five applications RxNetwork, Mango Health, MyMeds, C3HealthLink, and HuCare are discussed in detail. There are numerous studies looking at medication adherence. However, current literature regarding mobile applications to improve medication adherence is lacking. This article will provide pharmacists with a brief overview of the available mobile applications and features that could be used to improve patient adherence to medications. Existing mobile applications to improve medication adherence have ideal features that could help patients take medication as prescribed. Once further research is performed to establish their efficacy, pharmacists could begin to recommend mobile applications to their patients.

Psoriasis in childhood: effective strategies to improve treatment adherence

PubMed Central

Shah, Kara N; Cortina, Sandra; Ernst, Michelle M; Kichler, Jessica C

2015-01-01

Psoriasis is a relatively common chronic inflammatory skin disease in children for which there is no cure. Most children have mild disease that can be managed with topical therapy as opposed to phototherapy or systemic therapy. Despite the mild presentation of psoriasis in most children, the disease can have a significant impact on quality of life due to the need for ongoing treatment, the frequently visible nature of the cutaneous manifestations, and the social stigma that is associated with psoriasis. Adherence to treatment, in particular topical therapy, is often poor in adults and compromises response to therapy and medical provider management strategies. Multiple factors that may contribute to nonadherence in adults with psoriasis have been identified, including lack of education on the disease and expectations for management, issues related to ease of use and acceptability of topical medications, and anxiety regarding possible medication side effects. There is currently no published data on adherence in the pediatric psoriasis population; however, poor adherence is often suspected when patients fail to respond to appropriate therapy. General strategies used to assess adherence in other pediatric disease populations can be applied to children with psoriasis, and interventions that reflect experience in other chronic dermatologic disorders such as atopic dermatitis may also be helpful for medical providers caring for children with psoriasis.

Abstract Background As the case detection rates of hypertension increase in adult Nigerians, achieving target blood pressure (BP) control has become an important management challenge. Objectives To describe medication adherence and BP control amongst adult Nigerians with primary hypertension attending a primary care clinic of a tertiary hospital in a resource-poor environment in Eastern Nigeria. Methods A cross-sectional study was carried out in 140 adult patients with primary hypertension who have been on treatment for at least 6 months at the primary care clinic of Federal Medical Centre, Umuahia. A patient was said to have achieved goal BP control if the BP was < 140 per 90 mmHg. Adherence was assessed in the previous 30 days using a pretested researcher-administered questionnaire on 30 days of self-reported therapy. Adherence was graded using an ordinal scoring system of 0–4; an adherent patient was one who scored 4 points in the previous 30 days. Reasons for non-adherence were documented. Results Adherence to medication and BP control rates were 42.9% and 35.0% respectively. BP control was significantly associated with medication adherence (p = 0.03), antihypertensive medication duration ≥3 years (p = 0.042), and taking ≥ one form of antihypertensive medication (p = 0.04). BP at the recruitment visit was significantly higher than at the end of the study (p = 0.036). The most common reason for non-adherence was forgetfulness (p = 0.046). Conclusions The rate of BP control amongst the study population was low, which may be connected with low medication adherence. This study urges consideration of factors relating to adherence alongside other factors driving goal BP control.

BACKGROUND, AIMS, SETTINGS AND DESIGN: Poor adherence to oral maintenance chemotherapy can cause relapse of acute lymphoblastic leukemia (ALL). A multicenter study for the evaluation of adherence to oral 6-mercaptopurine (6-MP) maintenance chemotherapy for childhood ALL in Egypt to identify contributing factors and possible steps to promote adherence. The study included 129 children with ALL in complete remission receiving 6-MP single daily oral dose in the evening. Evaluation was done through specific questionnaires for the patients as well as serum 6-MP measurements. Nonadherence was detected in around 56% by questionnaires and around 50% by serum 6-MP level measurement. There was a highly significant correlation between nonadherence as found by the questionnaire and 6-MP level (P - 0.001). Nonadherence was significantly associated with low socioeconomic standard, noneducation and low educational level and large family size by both methods. High cost to come for follow-up visits was significant by questionnaire but not by 6-MP measurement. Adolescent age, the higher number of siblings, lack of written instructions, long time spent per visit, were all associated with higher rates of nonadherence, although none reached statistical significance. Nonadherence is a real problem in pediatric patients. Specific questionnaires can be an excellent reliable method for the routine follow-up of these children, and drug level assay can be requested only for confirmation. This protocol is especially effective in developing countries where financial resources may be limited. Every effort should be made to uncover its true incidence, contributing factors, and best methods of intervention.

2016-01-01

Background Long-term success of HIV antiretroviral therapy requires near-perfect adherence, maintained throughout one’s lifetime. However, perceptions towards ART and patterns of adherence may change during the life course. We assessed challenges to long-term adherence in adolescents and adults in three regional HIV treatment centers in Uganda. Methods We conducted 24 in-depth interviews and 2 focus group discussions with a total of 33 health-care providers and expert clients (HIV patients on long-term ART who assist with adherence support of fellow patients). Interview topics included experiences with patients on long-term treatment with either declining adherence or persistent poor adherence. Transcribed texts were coded and analyzed based on the social-ecological framework highlighting differences and commonalities between adolescents and adults. Results The overarching themes in adolescents were unstructured treatment holidays, delays in disclosure of HIV status by caretakers, stigma, which was mainly experienced in boarding schools, and diminishing or lack of clinical support. In particular, there was minimal support for early and gradual disclosure for caretakers to the infected children, diminishing clinical support for young adults during transition to adult-based care and declining peer-to-peer support group activities. The predominating theme in adults was challenges with treatment access among temporary economic migrants. Common themes to adults and adolescents were challenges with disclosure in intimate relationships, treatment related factors including side effects, supply of single tablets in place of fixed-dose combined drugs, supply of drug brands with unfavorable taste and missed opportunities for counseling due to shortage of staff. Conclusion Adherence counseling and support should be adapted differently for adolescents and adults and to the emerging life course challenges in long-term treated patients. Programs should also address constraints

Adherence to ART, fundamental to treatment success, has been poorly studied in India. Caregivers of children attending HIV clinics in southern India were interviewed using structured questionnaires. Adherence was assessed using a visual analogue scale representing past-month adherence and treatment interruptions >48 hours during the past 3 months. Clinical features, correlates of adherence and HIV-1 viral-load were documented. Based on caregiver reports, 90.9% of the children were optimally adherent. In multivariable analysis, experiencing ART-related adverse effects was significantly associated with suboptimal adherence (p=0.01). The proportion of children who experienced virological failure was 16.5%. Virological failure was not linked to suboptimal adherence. Factors influencing virological failure included running out of medications (p=0.002) and the child refusing to take medications (p=0.01). Inclusion of drugs with better safety profiles and improved access to care could further enhance outcomes. PMID:26443264

2015-01-01

The aim of our study was to identify representations about patient adherence among dermatologists (N=40) and their patients (N=153). A combined qualitative-quantitative methodology was applied. Dermatologists identified good doctor-patient relationship, information from the doctor, and background information as the most important determinants of adherence. In patients’ rankings, information from the doctor and understandable communication received the highest scores. Multidimensional scaling arranged patients’ results into four content groups which helped to reveal the structure of the representations. Our results may contribute to the evidence-based confirmation that transparency of views and expectations in doctor-patient communication is a basic determinant of successful adherence.

Though efficacious and affordable treatments for gout are widely available, gout is still not well controlled in many countries of the world including China.To investigate patient adherence to gout management recommendations and potential barriers in Chinese male gout patients, a survey was carried out by telephone interview in male patients registered in the gout clinic at Peking Union Medical College Hospital. Adherence to dietary and medication recommendations was measured by a food frequency questionnaire and proportion of cumulative time adherent to chemical urate-lowering therapy (ULT), respectively. Dietary adherence was defined as consumption of alcohol, seafood and animal organs less than once per month, and reduced red meat after dietary counseling. Medication adherence was defined as ULT ≥80% of time in the past 12 months for patients with indications. Logistic regression models were used to identify patient characteristics associated with management adherence. Reasons for nonadherence were also sought by open-end questions.Dietary and medication adherence were 44.2% and 21.9%, respectively. Older age (odds ratio [OR] 7.90, 95% confidence interval [CI] 2.49-25.04 for age ≥60), higher serum uric acid (sUA) levels (OR 3.53, 95% CI 1.42-8.75 for the highest quartile), and tophi (OR 2.31, 95% CI 1.12-4.77) were associated with dietary adherence independently, while tophi (OR 14.05, 95% CI 2.67-74.08) and chronic kidney disease (OR 16.66, 95% CI 2.63-105.37) were associated with medication adherence independently. Reasons that patients reported for nonadherence to medication included remission after treatment (35.3%), concerns for potential side effects (22.7%), insufficient patient education (8.7%), and adverse events (8.2%).Patient adherence to gout management recommendations is poor in China. Older age, increased disease burden, and specific comorbidities were associated with management adherence.

Hazardous alcohol consumption is a common diagnosis among people living with HIV infection. The relationship between alcohol consumption and poor adherence to antiretroviral therapy has been highlighted in different studies, yet few of them performed a parallel analysis of other substance use. In Spain, alcohol consumption is frequently associated with other substance use, mainly cannabis and cocaine. The aim of this study is to assess the influence of hazardous alcohol consumption both combined with other substances (cocaine, heroin, methadone and/or cannabis) or alone on antiretroviral therapy adherence in our social environment. We performed an observational case-control study including 119 HIV+ individuals. We recruited 40 non-adherent patients, defined by less than 90% compliance according to hospital pharmacy refill data, and corroborated by the Simplified Medication Adherence Questionnaire (SMAQ) and referring professional's opinion. Control cases (n=79) were defined as those patients with similar characteristics but considered adherent according to the same parameters. Data collection took place between May 2013 and September 2015. Statistical analysis was performed using a binary logistic regression model. Our results indicate that alcohol consumption decreases adherence to antiretroviral therapy. The use of methadone represents a statistically significant increased risk of poor adherence. No significant differences were found between adherent and non-adherent groups regarding cocaine, heroin or cannabis use in this study. In summary, the detection of substance use and especially alcohol consumption in HIV+ patients can improve the effectiveness of antiretroviral therapy by identifying and treating at-risk individuals for a poor therapeutic adherence.

The management of COPD is complex and patient adherence to treatment recommendations is known to be poor. In this paper the methods used for evaluating adherence in COPD are compared. Self-reporting has satisfactory reliability and offers a cheap, simple and easy method for assessing adherent behaviors. Unlike the objective measures of adherence such as electronic monitoring, self-reporting helps in identifying the reasons for nonadherence, which in turn would be useful in addressing adherence issues. Patients do not follow their treatment recommendations either intentionally or unintentionally. Intentional deviations are driven by patient beliefs and experiences about illness and treatment, which are in turn influenced by social and cultural factors. Unintentional deviations are often due to cognitive impairment and lack of routines. Factors associated with adherence in COPD have been explained using the Becker-Maiman model. Strategies for overcoming nonadherence have to be formulated based on the nature and reasons for nonadherence. In the event of unintentional nonadherence, the use of adherence aids like Dosette boxes, calendar packs and reminders should be promoted. Understanding patient beliefs and experiences, patient education focusing on the pathology of COPD and the role of treatment, periodic monitoring and reinforcement are critical for overcoming the barriers of intentional nonadherence.

Poor adherence is a common problem and may be an underlying cause of poor clinical outcomes. In pediatric populations, positive reinforcement techniques such as sticker charts may increase motivation to adhere to treatment regimens. To review the use of sticker charts to improve adherence in children with chronic disease, Medline and PsycINFO searches were conducted using the key words "positive reinforcement OR behavior therapy" and "adherence OR patient compliance" and "child." Randomized controlled retrospective cohort or single-subject-design studies were selected. Studies reporting adherence to the medical treatment of chronic disease in children using positive reinforcement techniques were included in the analysis. The systematic search was supplemented by identifying additional studies identified through the reference lists and authors of the initial articles found. Positive reinforcement techniques such as sticker charts increase adherence to medical treatment regimens. In several studies, this effect was maintained for months after the initial intervention. Better adherence correlated with better clinical outcomes in some, but not all, studies. Few studies examining the use of sticker charts were identified. Although single-subject-design studies are useful in establishing the effect of a behavioral intervention, larger randomized controlled trials would help determine the precise efficacy of sticker chart interventions. Adherence to medical treatments in children can be increased using sticker charts or other positive reinforcement techniques. This may be an effective means to encourage children with atopic dermatitis to apply their medications and improve clinical outcomes. © 2012 Wiley Periodicals, Inc.

Background Behavioral intervention outcomes for urinary incontinence (UI) depend on active patient participation. Objective The purpose of this study was to describe adherence to behavioral interventions (pelvic-floor muscle [PFM] exercises, UI prevention strategies, and delayed voiding), patient-perceived exercise barriers, and predictors of exercise adherence in women with urge-predominant UI. Design This was a prospectively planned secondary data analysis from a 2-stage, multicenter, randomized clinical trial. Patients and Intervention Three hundred seven women with urge-predominant UI were randomly assigned to receive either 10 weeks of drug therapy only or 10 weeks of drug therapy combined with a behavioral intervention for UI. One hundred fifty-four participants who received the combined intervention were included in this analysis. Measurements Pelvic-floor muscle exercise adherence and exercise barriers were assessed during the intervention phase and 1 year afterward. Adherence to UI prevention strategies and delayed voiding were assessed during the intervention only. Results During intervention, 81% of women exercised at least 5 to 6 days per week, and 87% performed at least 30 PFM contractions per day. Ninety-two percent of the women used the urge suppression strategy successfully. At the 12-month follow-up, only 32% of the women exercised at least 5 to 6 days per week, and 56% performed 15 or more PFM contractions on the days they exercised. The most persistent PFM exercise barriers were difficulty remembering to exercise and finding time to exercise. Similarly, difficulty finding time to exercise persisted as a predictor of PFM exercise adherence over time. Limitations Co-administration of medication for UI may have influenced adherence. Conclusions Most women adhered to exercise during supervised intervention; however, adherence declined over the long term. Interventions to help women remember to exercise and to integrate PFM exercises and UI prevention

Objectives Adherence to medical regimens for children and adolescents with chronic conditions is generally below 50% and is considered the single, greatest cause of treatment failure. As the prevalence of chronic illnesses in pediatric populations increases and awareness of the negative consequences of poor adherence become clearer, the need for reliable and valid measures of adherence has grown. Methods This review evaluated empirical evidence for 18 measures utilizing three assessment methods: (a) self-report or structured interviews, (b) daily diary methods, and (c) electronic monitors. Results Ten measures met the “well-established” evidence-based (EBA) criteria. Conclusions Several recommendations for improving adherence assessment were made. In particular, consideration should be given to the use of innovative technologies that provide a window into the “real time” behaviors of patients and families. Providing written treatment plans, identifying barriers to good adherence, and examining racial and ethnic differences in attitudes, beliefs and behaviors affecting adherence were strongly recommended.

To assess the different types of antibiotic-taking behavior and to compare self-reported with objectively measured adherence to antibiotic regimens in respiratory infections. This was a prospective study of patients with suspected bacterial pharyngitis and lower respiratory tract infections recruited from five primary care clinics in Catalonia. Adherence to various antibiotic regimens was assessed by the Medication Event Monitoring System (MEMS), which recorded every opening of the patient's bottle of tablets, and a self-reported adherence question. The outcome variables were antibiotic-taking adherence, correct dosing, and timing adherence. A total of 428 patients were included in the analysis. Five types of antibiotic use behavior were observed: excellent adherence (130 patients, 30.4%), acceptable adherence over time (53; 12.4%), declining adherence over time (123; 28.7%), non-adherence to correct dosing (108; 25.2%), and unacceptable adherence (14; 3.3%). Excellent adherence was significantly associated with the number of daily doses of antibiotic and antibiotic duration. A total of 254 patients reported never forgetting to take the antibiotic (59.3%), achieving a negative predictive value of 100% and a positive predictive value of 51.2%. Outpatients with respiratory infections treated with antibiotics showed poor adherence outcomes. Self-reported adherence was remarkably higher than that observed with the use of MEMS and failed to predict true patient adherence. Copyright © 2012 International Society for Infectious Diseases.

Brownbridge, G; Fielding, D M

1994-12-01

Sixty children and adolescents in end-stage renal failure who were undergoing either haemodialysis or continuous ambulatory peritoneal dialysis at one of five United Kingdom dialysis centres were assessed on psychosocial adjustment and adherence to their fluid intake, diet and medication regimes. Parental adjustment was also measured and data on sociodemographic and treatment history variables collected. A structured family interview and standardised questionnaire measures of anxiety, depression and behavioural disturbance were used. Multiple measures of treatment adherence were obtained, utilising children's and parents' self-reports, weight gain between dialysis, blood pressure, serum potassium level, blood urea level, dietitians' surveys and consultants' ratings. Correlational analyses showed that low treatment adherence was associated with poor adjustment to diagnosis and dialysis by children and parents (P < 0.01), self-ratings of anxiety and depression in children and parents (P < 0.001), age (adolescents tended to show poorer adherence than younger children, P < 0.001), duration of dialysis (P < 0.05), low family socioeconomic status (P < 0.05) and family structure (P < 0.01). These findings demonstrate the importance of psychosocial care in the treatment of this group of children. Future research should develop and evaluate psychosocial interventions aimed at improving treatment adherence.

Sypert, David; Van Dyke, Kenneth; Dhillon, Namrata; Elliott, John O; Jordan, Kim

The 2014 United States Preventive Services Task Force systematic review found abdominal aortic aneurysm (AAA) screening decreased related mortality by close to half. Despite the simplicity of screening, research suggests poor adherence to the recommended AAA screening guidelines. Using the quality improvement plan-study-do-act cycle, we retrospectively established poor adherence to AAA screening and poor documentation of smoking history in our resident clinic. An electronic reminder was prospectively implemented into our electronic medical record (EMR) with the goal of improving screening rates. After 1 year, a retrospective chart review was conducted. Comparisons of the pre- and post-electronic reminder intervention data were made using chi-square tests and odds ratios (OR). The purposeful AAA screening rate improved 27.8% during the intervention, 40.3% (95% confidence interval [CI]: 28.6-52.0%) versus 12.5% (95% CI: 3.1-21.9%), p = .002, suggesting patients were more likely to be screened as a result of the electronic reminder, OR = 4.73 (95% CI: 1.77-12.65). This improvement translates to a large effect size, Cohen's d = 0.86 (95% CI: 0.31-1.40). Electronic reminders are a simple EMR addition that can provide evidence-based education while improving adherence rates with preventive health screening measures.

Hyperphosphatemia in patients with ESRD: assessing the current evidence linking outcomes with treatment adherence

PubMed Central

2013-01-01

In recent years, the imbalance in phosphate homeostasis in patients with end-stage renal disease (ESRD) has been the subject of much research. It appears that, while hyperphosphatemia may be a tangible indicator of deteriorating kidney function, lack of phosphate homeostasis may also be associated with the increased risk of cardiovascular events and mortality that has become a hallmark of ESRD. The need to maintain phosphorus concentrations within a recommended range is reflected in evidence-based guidelines. However, these do not reflect serum phosphorus concentrations achieved by most patients in clinical practice. Given this discrepancy, it is important to consider ways in which dietary restriction of phosphorus intake and, in particular, use of phosphate binders in patients with ESRD can be made more effective. Poor adherence is common in patients with ESRD and has been associated with inadequate control of serum phosphorus concentrations. Studies indicate that, among other factors, major reasons for poor adherence to phosphate binder therapy include high pill burden and patients’ lack of understanding of their condition and its treatment. This review examines available evidence, seeking to understand fully the reasons underlying poor adherence in patients with ESRD and consider possible strategies for improving adherence in clinical practice.

Adherence to diet recommendations, fluid restriction, prescribed medications, and attendance at hemodialysis (HD) sessions are essential for optimal and effective treatment of patients with end-stage renal disease. No data regarding this issue are available from Palestine. Therefore, this study was carried out to assess adherence to diet, fluid restriction, medications, and HD sessions. A cross-sectional study of HD patients at An-Najah National University Hospital was carried out during summer, 2016. Self-reported adherence behavior was obtained using a valid and reliable questionnaire (End-Stage Renal Disease Adherence Questionnaire: ESRD-AQ). Predialytic serum levels of potassium and phosphate were obtained as clinical indicator of diet and medication adherence respectively. In addition, interdialytic body weight (IDW) was also obtained from medical records and analyzed in relation to reported adherence of fluid restriction. A total of 220 patients answered all questions pertaining to ESRD-AQ. The mean age ± standard deviation of participants was 56.82 ± 14.51 years. Dietary adherence was observed in 24% while that of fluid restriction adherence was observed in 31% of studied patients. Reported adherence to HD sessions was 52% while that for medications was 81%. Overall, 122 (55.5%) patients had good adherence, 89 (40.5%) had moderate adherence, and 9 (4.1%) had poor adherence behavior. Male patients had significantly higher overall adherence scores than females (p = 0.034). A significant correlation between reported diet adherence and serum pre-HD potassium level (p < 0.01) was observed. A significant correlation between reported fluid restriction adherence and IDW (p < 0.01) was also found. However, no significant correlation between reported adherence and pre-HD phosphate level. There was significant correlation between overall perception and overall adherence score (p < 0.001). Counselling of patients regarding importance of adherence

HIV medication adherence and HIV symptom severity: the roles of sleep quality and memory.

The purpose of the current study was to examine the extent to which self-reported sleep quality, a clinically malleable factor, is associated with both HIV medication adherence and self-reported HIV symptom severity. In addition, we sought to examine whether sleep quality may explain the association between HIV medication adherence and symptom severity, as well as the role of self-reported memory functioning in terms of the above relations. This study took place from April 2010 to March 2012. Participants were 129 HIV-positive individuals who completed an ART pill count and series of structured clinical interviews and self-report questionnaires on sleep, memory, and HIV symptom severity. A series of regressions were conducted to test study hypotheses. After accounting for covariates (i.e., problematic alcohol, nicotine, and cannabis use, and mood disorder diagnosis), results indicated that self-reported sleep quality was associated with HIV medication adherence and self-reported HIV symptom severity, and that sleep quality partially mediated the relation between medication adherence and self-reported HIV symptom severity. In addition, memory functioning moderated the relation between self-reported sleep quality and HIV symptom severity, such that the interaction of poor sleep quality and relatively good memory functioning was associated with heightened self-reported HIV symptom severity. This study highlights the importance of assessing sleep and memory among HIV-infected individuals as they may represent treatment targets for those experiencing poor medication adherence or particularly severe HIV symptoms. Such information could lead to the inclusion of adjunct brief interventions to target sleep and memory functioning in order to reduce symptom severity among HIV-positive individuals with poor medication adherence.

Self-reported poor dietary adherence following bariatric surgery is associated with less successful weight loss outcomes. Poor dietary adherence is a global construct lacking specificity regarding its underlying, clinically targetable, maladaptive eating behaviors. Comprehensive online survey data were obtained from a sample of 274 adults who underwent Roux-en-Y surgery in the prior 1-12 years. Correlations between dietary adherence and six eating-related behaviors were calculated, with the frequency of each behavior reported on a 7-point scale. Linear regression modeling was applied. All six maladaptive eating behaviors were highly correlated with dietary adherence (Pearson's r > 0.5): grazing (r = - 0.565), mindless eating (r = - 0.572), loss of control eating (r = - 0.517), eating "more than is best" after dinner (r = - 0.518), eating foods off of one's plan (r = - 0.557), and "when I eat something off-plan, I feel like I have blown it and I give up and eat more" (r = - 0.574). The estimated regression coefficients in the linear model was statistically significant, [F(5, 261) = 60.006, p < 0.001] and accounted for approximately 54% of the variance of global dietary adherence (R 2  = 0.535, adjusted R 2  = 0.526). Six maladaptive eating behaviors accounted for a highly significant portion of post-Roux-en-Y patients' poor self- reported dietary adherence. Prospective studies are needed to investigate the relationship between targetable maladaptive eating behaviors and bariatric surgery outcomes.

Clarifying the Concept of Adherence to eHealth Technology: Systematic Review on When Usage Becomes Adherence

Kelders, Saskia M; van Gemert-Pijnen, Julia EWC

2017-01-01

Background In electronic health (eHealth) evaluations, there is increasing attention for studying the actual usage of a technology in relation to the outcomes found, often by studying the adherence to the technology. On the basis of the definition of adherence, we suggest that the following three elements are necessary to determine adherence to eHealth technology: (1) the ability to measure the usage behavior of individuals; (2) an operationalization of intended use; and (3) an empirical, theoretical, or rational justification of the intended use. However, to date, little is known on how to operationalize the intended usage of and the adherence to different types of eHealth technology. Objective The study aimed to improve eHealth evaluations by gaining insight into when, how, and by whom the concept of adherence has been used in previous eHealth evaluations and finding a concise way to operationalize adherence to and intended use of different eHealth technologies. Methods A systematic review of eHealth evaluations was conducted to gain insight into how the use of the technology was measured, how adherence to different types of technologies was operationalized, and if and how the intended use of the technology was justified. Differences in variables between the use of the technology and the operationalization of adherence were calculated using a chi-square test of independence. Results In total, 62 studies were included in this review. In 34 studies, adherence was operationalized as “the more use, the better,” whereas 28 studies described a threshold for intended use of the technology as well. Out of these 28, only 6 reported a justification for the intended use. The proportion of evaluations of mental health technologies reporting a justified operationalization of intended use is lagging behind compared with evaluations of lifestyle and chronic care technologies. The results indicated that a justification of intended use does not require extra measurements to

Early adherence is key to successful depression treatment, but nearly 60% of patients discontinue antidepressants within 3 months. Our study aimed to determine factors associated with poor early adherence to antidepressants in a large diverse sample of patients. Six Mental Health Research Network healthcare systems contributed data for adults with depression and a new antidepressant start, defined by a washout period of at least 270 days, between January 1, 2010 and December 31, 2012. Pharmacy fill and self-reported race/ethnicity data were obtained from the electronic medical record. Patients had early adherence if they had a second antidepressant fill within 180 days of the first. We used logistic regression to investigate the relationship between early adherence and patient characteristics. A total of 177,469 adult patients had 184,967 new episodes of depression with a filled antidepressant prescription. Patients refilled their antidepressants within 180 days in 71% of episodes. Race/ethnicity was a strong predictor of early adherence, with patients from racial/ethnic minorities other than Native Americans/Alaskan Natives less likely (adjusted odd ratios 0.50-0.59) to refill their antidepressants than non-Hispanic whites. Age, neighborhood education, comorbidity burden, provider type and engagement in psychotherapy were also associated with adherence. Other apparent predictors of early adherence, including neighborhood income, gender, and prior mental health hospitalizations, were no longer significant in the fully adjusted model. Race/ethnicity was a robust predictor of early antidepressant adherence, with minority groups other than Native Americans/Alaskan Natives less likely to be adherent. Further research is needed to determine whether early nonadherence in specific minority populations is intentional, due to side effects or patient preference, or unintentional and appropriate for targeted interventions to improve adherence. © 2016 Wiley Periodicals, Inc.

Relation between adherence and outcome in the group treatment of insomnia.

Vincent, Norah K; Hameed, Hannah

2003-01-01

This study evaluated adherence to group cognitive behavioral treatment in 50 adults with chronic insomnia. Adherence was measured using questionnaire data, consistency of sleep scheduling, and % of sessions attended. Results showed that therapists' rated 48% of participants as "very much" to "extremely" adherent. Using stepwise regression, only therapist-rated adherence explained a significant amount of variance in post-treatment outcome. Therapist-rated adherence predicted post-treatment ratings of sleep-related impairment, dysfunctional beliefs about sleep, and overall sleep quality (but not actual sleep duration or efficiency). Using a multivariate analysis of variance (MANOVA) procedure, results revealed that a diagnosis of dysthymia, based on a structured clinical interview, was associated with reduced adherence and less improvement in sleep-onset latency and sleep efficiency, but that scores on a dimensional measure of depression were not associated with either adherence or outcome. Implications of these findings are that the practice of treatment techniques is related to an improved perception of sleep and more healthy and appropriate beliefs about the causes of poor sleep. Therapists should continue to pay close attention to the adherence behavior of those with insomnia, particularly if they are depressed.

Effect of drug reminder packaging on medication adherence: a systematic review revealing research gaps

PubMed Central

2014-01-01

Background This was a systematic review of the literature in accordance with the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) statement. Evidence mapping was used to reveal the effect of drug reminder packaging on medication adherence, to identify research gaps and to make suggestions for future research. Methods PubMed, Embase, CINAHL and PsycINFO were searched with an end date of September 2013 using the Medical Subject Headings (MeSH) term ‘medication adherence’ and 20 different search terms for ‘drug reminder packaging’, limited to the English and German languages. Additional references were identified through cross-referencing. All prospective controlled trials with an intervention using drug reminder packaging for patients taking at least one medication without the assistance of a health-care professional were included in the evidence mapping of the effect of drug reminder packaging on adherence and outcomes according to the Economic, Clinical and Humanistic Outcomes (ECHO) model. Results A total of 30 studies met the inclusion criteria: 10 randomized controlled trials, 19 controlled clinical trials and 1 cohort study. Drug reminder packaging had a significant effect on at least one adherence parameter in 17 studies (57%). The methodological quality was strong in five studies. Two studies provided complete information. Clear research gaps emerged. Conclusions Overall, the studies showed a positive effect of drug reminder packaging on adherence and clinical outcomes. However, poor reporting and important gaps like missing humanistic and economic outcomes and neglected safety issues limit the drawing of firm conclusions. Suggestions are made for future research.

2014-01-01

Limited health literacy has been shown to contribute to poor health, including poor adherence to antiretroviral therapy (ART) in people living with HIV/AIDS, over and above other indicators of social disadvantage and poverty. Given the mixed results of previous interventions for people with HIV and low health literacy, investigating possible targets for improved adherence is warranted. The present study aims to identify the correlates of optimal and suboptimal outcomes among participants of a recent skills-based medication adherence intervention (Kalichman et al., 2013). Participants included in this secondary analysis were 188 men and women living with HIV who had low health literacy as determined by scoring ≤90% on a test of health literacy and had complete viral load data for baseline and follow-up. Participants completed physical, psychosocial and literacy measures using computerized interviews. Adherence was assessed by unannounced pill count and follow-up viral loads were assessed by blood draw. Results showed that higher levels of health literacy and lower levels of alcohol use were the strongest predictors of achieving HIV viral load optimal outcomes. The interplay between lower health literacy and alcohol use on adherence should be the focus of future research. PMID:25211524

The Dutch guideline for the treatment of depression in young people recommends initiating antidepressant treatment with fluoxetine, as the evidence for its efficacy is strongest and the risk of suicidality may be lower than with other antidepressants. Furthermore, low starting doses are recommended. We aimed to determine whether antidepressant prescriptions are in accord with guidelines. A cohort of young people aged between 6 and 17 at the time of antidepressant initiation was selected from IABD, a Dutch pharmacy prescription database. The percentage of prescriptions for each antidepressant was determined. Starting and maintenance doses were determined and compared with recommendations for citalopram, fluoxetine, fluvoxamine, and sertraline. During the study period, 2942 patients initiated antidepressant treatment. The proportion of these young people who were prescribed fluoxetine increased from 10.1 % in 1994-2003 to 19.7 % in 2010-2014. However, the most commonly prescribed antidepressants were paroxetine in 1994-2003 and citalopram in 2004-2014. The median starting and maintenance doses were ≤0.5 DDD/day for tricyclic antidepressants and 0.5-1 DDD/day for SSRIs and other antidepressants. Starting doses were guideline-concordant 58 % of the time for children, 31 % for preteens, and 16 % for teens. Sixty percent of teens were prescribed an adult starting dose. In conclusion, guideline adherence was poor. Physicians preferred citalopram over fluoxetine, in contrast to the recommendations. Furthermore, although children were prescribed a low starting dose relatively frequently, teens were often prescribed an adult starting dose. These results suggest that dedicated effort may be necessary to improve guideline adherence.

Behavioral interventions for insomnia are effective in improving sleep, yet adherence is variable, and predictors of adherence have not been consistently replicated. The relationships between daily variations in state factors at the initiation of treatment and adherence have not been investigated. Using 2-week, self-report online logs, this study determined, among 53 college students with probable insomnia, the associations of pretreatment factors and daily factors during treatment on daily variations in adherence to one session of behavioral treatments for insomnia. These treatments included stimulus control therapy (SCT), sleep restriction therapy (SRT), and sleep hygiene (SH). Low self-efficacy was associated with poorer SCT and SH adherence. Participants with a "bed partner or pet" at least some of the time had better SCT adherence. Greater total sleep time and poorer sleep quality were associated with poor SCT and SRT adherence the following night. Greater sleep efficiency was related to greater next night SCT and SRT adherence. Alcohol consumption was related to poorer SRT and SH adherence the following night. Future studies should test the replicability of these findings. Adherence trials may want to test whether discouraging alcohol intake, enhancing treatment-related self-efficacy, and monitoring and providing feedback on sleep, early in treatment, affects adherence.

COPD affects millions of people worldwide. Poor treatment adherence contributes to increased symptom severity, morbidity and mortality. This study was designed to investigate adherence to COPD treatment in Turkey and Saudi Arabia. An observational, cross-sectional study in adult COPD patients in Turkey and Saudi Arabia. Through physician-led interviews, data were collected on sociodemographics and disease history, including the impact of COPD on health status using the COPD Assessment Test (CAT); quality of life, using the EuroQol Five-Dimension questionnaire (EQ-5D); and anxiety and depression using the Hospital Anxiety and Depression Scale (HADS). Treatment adherence was measured using the 8-item Morisky Medication Adherence Scale (MMAS-8). Multivariate logistic regression analysis examined the predictors of non-adherence and the impact of adherence on symptom severity. Four hundred and five COPD patients participated: 199 in Turkey and 206 in Saudi Arabia. Overall, 49.2% reported low adherence (MMAS-8 <6). Of those, 74.7% reported high disease impact (CAT >15) compared to 58.4% reporting medium/high adherence ( p =0.0008). Patients with low adherence reported a lower mean 3-level EQ-5D utility value (0.54±0.35) compared to those with medium/high adherence (0.64±0.30; p <0.0001). Depression with HADS score 8-10 or >10 was associated with lower adherence (OR 2.50 [95% CI: 1.43-4.39] and 2.43 [95% CI: 1.39-4.25], respectively; p =0.0008). Being a high school/college graduate was associated with better adherence compared with no high school (OR 0.57 [95% CI: 0.33-0.98] and 0.38 [95% CI: 0.15-1.00], respectively; p =0.0310). After adjusting for age, gender, and country, a significant association between treatment adherence (MMAS-8 score ≥6) and lower disease impact (CAT ≤15) was observed (OR 0.56 [95% CI: 0.33-0.95]; p =0.0314). Adherence to COPD treatment is poor in Turkey and Saudi Arabia. Non-adherence to treatment is associated with higher disease impact

Adherence is defined as the extent to which a person's behavior corresponds with recommendations from health care providers. Adherence to treatment is an important factor for a good therapeutic outcome. This study aimed to examine the adherence of patients with tinea pedis and to clarify the factors related to it. We assessed medication adherence for oral and topical drugs using a translated version of the Morisky Medication Adherence Scale-8 (MMAS-8) together with other background factors in 445 Japanese patients with tinea pedis, using a questionnaire in a web-based monitoring system. Overall, high, medium and low adherence rates as assessed by MMAS-8 were 8.7%, 31.7% and 59.6% for oral medication, and 8.6%, 17.4% and 74.0% for topical medication, respectively. The adherence level was significantly higher for oral medication than for topical medication. Subgroup analyses showed that the adherence level for topical medication was significantly higher when topical and oral medications were used in combination than when topical medication was used alone. A low adherence level was shown in employed patients, those for whom their oral medication had not been effective and those with topical medication who had visited their hospital less often than once every six months. Patient adherence to therapy can be effectively improved by selecting highly effective medication while considering the prescription of topical and oral antifungal medications concomitantly, by carefully selecting a therapy plan for employed patients and by encouraging patients to visit their doctor regularly.

Patient adherence is a critical factor for success of patient-administered therapies, including incentive spirometry (IS). Patient adherence with IS is not known, so we sought to evaluate providers' perspectives on the current state of IS adherence and elucidate possible factors hindering patient adherence. Respiratory therapists (RTs) and nurses across the United States were surveyed via social media and online newsletters. Surveys were distributed to the relevant national RT and nursing societies: the American Association for Respiratory Care, the Academy of Medical-Surgical Nurses, the American Society of Peri-Anesthesia Nurses, and the American Association of Critical-Care Nurses. Responses from 1,681 (83.8% completion rate) RTs and nurses were received. The clear majority of all providers agreed that patient adherence is poor (86.0%; 1,416 of 1,647 respondents) and should be improved (95.4%; 1,551 of 1,626 respondents). Providers believe that IS adherence is hindered by various factors. The most common reasons cited were that patients forget to use their ISs (83.5%; 1,404 of 1,681 respondents), do not use them effectively (74.4%; 1,251 of 1,681 respondents), and do not use them frequently enough (70.7%; 1,188 of 1,681 respondents). These findings from a large national survey of health care providers highlight the need for improved IS adherence and indicate that patient forgetfulness may be a large contributor to nonadherence. Efforts aimed at improving IS adherence are warranted. Copyright © 2018 by Daedalus Enterprises.

It is challenging for dialysis patients to maintain adherence to their medical regimen, and symptoms of depression are prevalent among them. Limited data is available about adherence and depression among patients receiving peritoneal dialysis (PD). This study aimed to examine the rates of treatment non-adherence and depression in PD patients. A total of 20 PD patients (response rate 71.4%; mean age 64.4 ± 11.6 years) were assessed using the Beliefs about Medicines Questionnaire, Self Efficacy for Managing Chronic Disease Scale, Hospital Anxiety and Depression Scale (HAD) and Kidney Disease Quality of Life-Short Form. A self-reported adherence (PD exchanges, medication and diet) scale developed for the study was also included. Medical information (e.g. most recent biochemistry results) was obtained from chart review. The mean self-reported scores indicated an overall high level of adherence, although a significant proportion of patients were non-adherent. Among the latter, 20% of patients were non-adherent to medication and 26% to diet due to forgetfulness, while 15% and 26% of patients admitted to deliberate non-adherence to medication and diet, respectively. Treatment modality, employment, self-care status and self-efficacy were associated with overall adherence. Using a cutoff point of 8 for HAD depression and anxiety subscales, 40% of patients were found to be depressed and 30% had symptoms of anxiety. This is the first study to document treatment adherence and depression among PD patients in Singapore. Findings of high prevalence of depression and anxiety, and reports of poor adherence warrant development of intervention programmes.

Understanding how adherence goals promote adherence behaviours: a repeated measure observational study with HIV seropositive patients

PubMed Central

2012-01-01

Background The extent to which patients follow treatments as prescribed is pivotal to treatment success. An exceptionally high level (> 95%) of HIV medication adherence is required to suppress viral replication and protect the immune system and a similarly high level (> 80%) of adherence has also been suggested in order to benefit from prescribed exercise programmes. However, in clinical practice, adherence to both often falls below the desirable level. This project aims to investigate a wide range of psychological and personality factors that may lead to adherence/non-adherence to medical treatment and exercise programmes. Methods HIV positive patients who are referred to the physiotherapist-led 10-week exercise programme as part of the standard care are continuously recruited. Data on social cognitive variables (attitude, intention, subjective norms, self-efficacy, and outcome beliefs) about the goal and specific behaviours, selected personality factors, perceived quality of life, physical activity, self-reported adherence and physical assessment are collected at baseline, at the end of the exercise programme and again 3 months later. The project incorporates objective measures of both exercise (attendance log and improvement in physical measures such as improved fitness level, weight loss, improved circumferential anthropometric measures) and medication adherence (verified by non-invasive hair analysis). Discussion The novelty of this project comes from two key aspects, complemented with objective information on exercise and medication adherence. The project assesses beliefs about both the underlying goal such as following prescribed treatment; and about the specific behaviours such as undertaking the exercise or taking the medication, using both implicit and explicit assessments of patients’ beliefs and attitudes. We predict that i) the way people think about the underlying goal of their treatments explains medication and exercise behaviours over and above

We aimed to design a multimodal intervention to improve adherence following first episode psychosis, consistent with current evidence. Existing literature identified medication attitudes, insight, and characteristics of support as important determinants of adherence to medication: we examined medication attitudes, self-esteem, and insight in an early psychosis cohort better to understand their relationships. Existing longitudinal data from 309 patients with early Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition, nonaffective psychosis (83% first episode) were analyzed to test the hypothesis that medication attitudes, while meaningfully different from “insight,” correlated with insight and self-esteem, and change in each influenced the others. Rosenberg Self-Esteem Scale, Birchwood Insight Scale, and Positive and Negative Syndrome Scale insight were assessed at presentation, after 6 weeks and 3 and 18 months. Drug Attitudes Inventory (DAI) and treatment satisfaction were rated from 6 weeks onward. Structural equation models of their relationships were compared. Insight measures’ and DAI’s predictive validity were compared against relapse, readmission, and remission. Analysis found five latent constructs best fitted the data: medication attitudes, self-esteem, accepting need for treatment, self-rated insight, and objective insight. All were related and each affected the others as it changed, except self-esteem and medication attitudes. Low self-reported insight at presentation predicted readmission. Good 6-week insight (unlike drug attitudes) predicted remission. Literature review and data modeling indicated that a multimodal intervention using motivational interviewing, online psychoeducation, and SMS text medication reminders to enhance adherence without damaging self-concept was feasible and appropriate.

Patient-identified barriers to immunosuppressive medications are associated with poor adherence and negative clinical outcomes in transplant patients. Assessment of adherence barriers is not part of routine post-transplant care, and studies regarding implementing such a process in a reliable way are lacking. Using the Model for Improvement and PDSA cycles, we implemented a system to identify adherence barriers, including patient-centered design of a barriers assessment tool, identification of eligible patients, clear roles for clinic staff, and creating a culture of non-judgmental discussion around adherence. We performed time-series analysis of our process measure. Secondary analyses examined the endorsement and concordance of adherence barriers between patient-caregiver dyads. After three methods of testing, the most reliable delivery system was an EHR-integrated tablet that alerted staff of patient eligibility for assessment. Barriers were endorsed by 35% of caregivers (n=85) and 43% of patients (n=60). The most frequently patient-endorsed barriers were forgetting, poor taste, and side effects. Caregivers endorsed forgetting and side effects. Concordance between patient-caregiver dyads was fair (k=0.299). Standardized adherence barriers assessment is feasible in the clinical care of pediatric kidney transplant patients. Features necessary for success included automation, redundant systems with designated staff to identify and mitigate failures, aligned reporting structures, and reliable measurement approaches. Future studies will examine whether barriers predict clinical outcomes (eg, organ rejection, graft loss). © 2017 John Wiley & Sons A/S. Published by John Wiley & Sons Ltd.

Background Poor adherence is the main barrier to the effectiveness of HIV medication. The objective of this study was to explore and conceptualize patterns and difficulties in physicians' work with patients' adherence to HIV medication. No previous studies on this subject have directly observed physicians' behavior. Methods This is a qualitative, cross-sectional study. We used a Grounded Theory approach to let the main issues in physicians' work with patients' adherence emerge without preconceiving the focus of the study. We included physicians from HIV clinics in San Francisco, U.S.A. as well as from Copenhagen, Denmark. Physicians were observed during their clinical work and subsequently interviewed with a semi-structured interview guide. Notes on observations and transcribed interviews were analyzed with NVivo software. Results We enrolled 16 physicians from San Francisco and 18 from Copenhagen. When we discovered that physicians and patients seldom discussed adherence issues in depth, we made adherence communication and its barriers the focus of the study. The main patterns in physicians' communication with patients about adherence were similar in both settings. An important barrier to in-depth adherence communication was that some physicians felt it was awkward to explore the possibility of non-adherence if there were no objective signs of treatment failure, because patients could feel "accused." To overcome this awkwardness, some physicians consciously tried to "de-shame" patients regarding non-adherence. However, a recurring theme was that physicians often suspected non-adherence even when patients did not admit to have missed any doses, and physicians had difficulties handling this low believability of patient statements. We here develop a simple four-step, three-factor model of physicians' adherence communication. The four steps are: deciding whether to ask about adherence or not, pre-questioning preparations, phrasing the question, and responding to the

Phosphate control is a crucial treatment goal in end-stage renal disease, but poor patient adherence to phosphate binder therapy remains a challenge. This study aimed to estimate the extent of phosphate binder adherence in hemodialysis patients and to identify potential determinants. Phosphate binder adherence was measured blindly in 135 hemodialysis patients for 2 months using the medication event monitoring system. Patient data, gathered at inclusion through medical records, ad hoc questionnaires and the short form (SF)-36 health survey, included: (1) demographics, (2) perceived side-effects, belief in benefit, self-reported adherence to the therapy, (3) knowledge about phosphate binder therapy, (4) social support, and (5) quality of life (SF-36). Phosphatemia data was collected from charts. 'Being adherent' was defined as missing <1 total daily dose/week and 'being totally adherent' as missing <1 total daily dose/week, every week. Mean age of patients was 67 years and 64 % of the sample was male. Over the 2 months, 78 % of the prescribed doses were taken. Every week, about half of patients were adherent. Over the entire 8-week period, 22 % of patients were totally adherent. Mean phosphatemia levels were 0.55 mg/dl lower in adherent than nonadherent patients (4.76 vs. 5.31 mg/dl). Determinants for being totally adherent were living with a partner, higher social support (both were interrelated) and higher physical quality of life. Experiencing intake-related inconvenience negatively affected adherence. The social support and quality of life physical score explained 26 % of the variance in adherence. Phosphate binder nonadherence remains a major problem. Interventions should aim, at least, to improve social support. With few associated factors found and yet low adherence, an individualized approach seems indicated.

Summary Background Treatment regimens for patients with cystic fibrosis (CF) are time-consuming and complex, resulting in consistently low adherence rates. To date, few studies have evaluated innovative technologies to improve adherence in this population. Current infection control guidelines for patients with CF seek to minimize patient-to-patient transmission of potential pathogens. Thus, interventions must avoid face-to-face contact and be delivered individually, limiting opportunities for peer support. This study aimed to develop and assess a web-enabled cell phone, CFFONE™, designed to provide CF information and social support to improve adherence in adolescents with CF. Methods The acceptability, feasibility, and utility of CFFONE™ were evaluated with health care professionals (n = 17) adolescents with CF aged 11–18 years old (n = 12), adults with CF aged 21–36 years old (n = 6), parents of adolescents with CF (n = 12), and technology experts (n = 8). Adolescents also tested a prototype of CFFONE™ (n = 9). Qualitative and quantitative data were collected. Results Focus group data with health care = professionals indicated a need for this intervention, and indicated that CFFONE™ would be likely to improve knowledge and social support, and somewhat likely to improve adherence. Adolescent, adults, and parents all rated CFFONE™ as likely to improve adherence. Technology experts rated the prototype design and format as appropriate. Conclusions The current study provided some support from key stakeholders for this intervention to improve adherence in adolescents with CF. Next steps include a multi-center trial of the efficacy and safety of CFFONE™. PMID:20054860

There is uncertainty regarding the durability of adherence to antiretroviral therapy. This study is a retrospective review of previously antiretroviral naïve patients initiating therapy between 1997 and 2002. Antiretroviral adherence was calculated using prescription refill data and was analyzed over time on an initial regimen and on sequential antiretroviral regimens. Three hundred forty-four patients were included. The median lengths of the first, second, and third regimens were stable at 1.7 years, 1.2 years, and 1.5 years, respectively (p = 0.10). In multivariate analysis the factor most significantly associated with earlier initial regimen termination was poor adherence. On an initial regimen, adherence decreased over time and declined most rapidly in patients with the shortest regimens (4 to <16 months, −43% per year), followed by patients with intermediate regimen duration (16 to <28 months, −19% per year), and then patients with longer regimens (≥28 months, −5% per year). In patients progressing to a third regimen, there was a trend toward decreasing adherence over successive regimens. In conclusion, sequential antiretroviral regimens are of similar lengths, with adherence being highly associated with first regimen duration. Adherence decreases during an initial regimen and on sequential antiretroviral regimens. Effective and durable interventions to prevent declining adherence are needed. PMID:16987049

Structural barriers to ART adherence in Southern Africa: challenges and potential ways forward

KAGEE, A.; REMIEN, R.H.; BERKMAN, A.; HOFFMAN, S.; CAMPOS, L.; SWARTZ, L.

2010-01-01

Structural barriers to antiretroviral treatment (ART) adherence are economic, institutional, political and cultural factors, that collectively influence the extent to which persons living with HIV follow their medication regimens. We identify three sets of structural barriers to ART adherence that are salient in Southern Africa: poverty-related, institutional, and political and cultural. Examples of poverty-related barriers are competing demands in the context of resource-constrained settings, the lack of transport infrastructure, food insecurity, the role of disability grants and poor social support. Examples of institutional factors are logistical barriers, overburdened health care facilities, limited access to mental health services and difficulties in ensuring adequate counseling. Examples of political and cultural barriers are controversies in the provision of treatment for AIDS, migration, traditional beliefs about HIV and AIDS, poor health literacy and gender inequalities. In forging a way forward, we identify ways in which individuals, communities and health care systems may overcome some of these structural barriers. Finally, we make recommendations for further research on structural barriers to ART adherence. In all likelihood, enhancing adherence to ART requires the efforts of a variety of disciplines, including public health, psychology, anthropology, sociology and medicine. PMID:20509066

Cystic Fibrosis (CF) management requires complex treatment regimens but adherence to treatment is poor and has negative health implications. There are various methods of measuring adherence, but little is known regarding the extent of adherence measurement in CF centres throughout the UK and Ireland. To determine the adherence monitoring practices in CF centres throughout the UK and Ireland, and to establish CF pharmacists' views on these practices. UK and Ireland Cystic Fibrosis Pharmacists' Group's annual meeting (2014). A questionnaire was designed, piloted and distributed to pharmacists attending the UK and Ireland Cystic Fibrosis Pharmacists' Group's annual meeting (2014). The main outcome measures were the methods of inhaled/nebulised antibiotic supply and the methods used to measure treatment adherence in CF centres. The questionnaire also ascertained the demographic information of participating pharmacists. Closed question responses were analysed using descriptive statistics. Open questions were analysed using content analysis. Twenty-one respondents (84 % response) were included in the analysis and were mostly from English centres (66.7 %). Detailed records of patients receiving their inhaled/nebulised antibiotics were lacking. Adherence was most commonly described to be measured at 'every clinic visit' (28.6 %) and 'occasionally' (28.6 %). Patient self-reported adherence was the most commonly used method of measuring adherence in practice (90.5 %). The availability of electronic adherence monitoring in CF centres did not guarantee its use. Pharmacists attributed an equal professional responsibility for adherence monitoring in CF to Consultants, Nurses and Pharmacists. Seventy-six percent of pharmacists felt that the current adherence monitoring practices within their own unit were inadequate and associated with the absence of sufficient specialist CF pharmacist involvement. Many suggested that greater specialist pharmacist involvement could facilitate

The association between non-adherence to medication and health-related quality-of-life (HRQoL) in Chronic Obstructive Pulmonary Disease (COPD) remains poorly understood. Different ways to deal with methodological challenges to estimate this association have probably contributed to conflicting results. To investigate the association between medication adherence and HRQoL, thereby illustrating methodological challenges that need to be addressed. We used longitudinal patient-level data from a cluster-randomized controlled trial (i.e. RECODE) including three-year data on type and dose of COPD maintenance medication prescribed and HRQoL (Clinical COPD Questionnaire [CCQ], st. George Respiratory Questionnaire [SGRQ], EuroQol 5-dimensions [EQ-5D]) of 511 patients. A linear mixed model was used to assess the association between adherence and HRQoL using a fixed cut-off of 80% of the proportion of days covered (PDC) to define adherence. Subsequently, we investigated the impact of differences in disease severity; lifestyle; and reversed causality, representing the methodological challenges. Additionally, we investigated the impact of changing the definition of adherence. In unadjusted analyses, and analyses adjusting for demographic characteristics only, SGRQ score was worse in the adherent compared to the non-adherent group. This association disappeared when correcting for disease severity and/or lifestyle. A better SGRQ score was predictive of decreased adherence in the following year. However, accounting for the previous HRQoL did not result in positive associations between adherence and HRQoL. When defining four categories of adherence, patients with a PDC between 80 and 99% had a significantly worse SGRQ score compared to patients with a PDC <60%, even after correction for lifestyle. There was no significant association between adherence and CCQ or EQ-5D. This study showed persistent methodological challenges in the investigation of the effect of medication adherence on

As online health information becomes common, it is important to assess patients' access to and experiences with online resources. We examined whether glaucoma patients' technology usage differs by medication adherence and whether adherence is associated with online education experiences. We included 164 adults with glaucoma taking ≥1 glaucoma medication. Participants completed a survey including demographic and health information, the Morisky Adherence Scale, and questions about online glaucoma resource usage. Differences in technology access, adherence, and age were compared with chi-squared, Fisher exact, and two-sample t-tests. Mean age was 66 years. Twenty-six percent reported poor adherence. Eighty percent had good technology access. Seventy-three percent of subjects with greater technology access wanted online glaucoma information and yet only 14% of patients had been directed to online resources by physicians. There was no relationship between technological connectivity and adherence (p = 0.51). Nonadherent patients were younger (mean age 58 years vs. 66 years for adherent patients, p = 0.002). Nonadherence was associated with negative feelings about online searches (68% vs. 42%, p = 0.06). Younger, poorly adherent patients navigate online glaucoma resources without physician input. These online searches are often unsatisfying. Technology should be leveraged to create high quality, online glaucoma resources that physicians can recommend to provide guidance for disease self-management.

Relations between cognitive status and medication adherence in patients treated for memory disorders

2012-01-01

Medication adherence has been increasingly recognized as an important factor in elderly persons' health. Various studies have shown that medication non-adherence is associated with poor health status in this population. As part of a study of the effects of two interventions to promote medication adherence in patients treated for memory problems, information on medication adherence and cognitive status was collected at 3-month intervals. Twenty-seven participants (16 men, 11 women, age 71–92 years) were assigned to control or treatment conditions and adherence was evaluated with an electronic monitoring device. Cognitive status was evaluated at 3-month intervals beginning in April of 2003 and continuing through September of 2006. We have previously reported on the effectiveness of these interventions to promote adherence. In this paper, we examine the relations of cognitive status and adherence over time using a partial least squares path model in order to evaluate the extent to which adherence to cholinesterase medications was related to cognitive status. Adherence predicted cognitive status at later time points while cognition did not, in general, predict adherence. Results thus suggest that interventions to ensure high levels of medication adherence may be important for maintaining cognitive function in affected elderly people. PMID:24575293

We aimed to design a multimodal intervention to improve adherence following first episode psychosis, consistent with current evidence. Existing literature identified medication attitudes, insight, and characteristics of support as important determinants of adherence to medication: we examined medication attitudes, self-esteem, and insight in an early psychosis cohort better to understand their relationships. Existing longitudinal data from 309 patients with early Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition, nonaffective psychosis (83% first episode) were analyzed to test the hypothesis that medication attitudes, while meaningfully different from "insight," correlated with insight and self-esteem, and change in each influenced the others. Rosenberg Self-Esteem Scale, Birchwood Insight Scale, and Positive and Negative Syndrome Scale insight were assessed at presentation, after 6 weeks and 3 and 18 months. Drug Attitudes Inventory (DAI) and treatment satisfaction were rated from 6 weeks onward. Structural equation models of their relationships were compared. Insight measures' and DAI's predictive validity were compared against relapse, readmission, and remission. Analysis found five latent constructs best fitted the data: medication attitudes, self-esteem, accepting need for treatment, self-rated insight, and objective insight. All were related and each affected the others as it changed, except self-esteem and medication attitudes. Low self-reported insight at presentation predicted readmission. Good 6-week insight (unlike drug attitudes) predicted remission. Literature review and data modeling indicated that a multimodal intervention using motivational interviewing, online psychoeducation, and SMS text medication reminders to enhance adherence without damaging self-concept was feasible and appropriate. © The Author 2015.

In this prospective, randomized clinical trial, correlates of adherence to antiretroviral therapy (ART) were assessed using a baseline questionnaire among 68 rural women living with AIDS (WLA) in India. Unadjusted analyses revealed positive relationships of ART adherence with Hindu religion, and support from spouses and parents, whereas negative associations were found with depression, poor quality of life, and having ten or more HIV symptoms. Multiple linear regression analysis also revealed that WLA who were Hindu, not depressed, had ART support from spouses and parents, and perceived some benefit from ART were more adherent to ART than their respective counterparts. This study reveals the unique challenges which rural WLA experience and the need to mitigate these challenges early in ART treatment. Further, the findings enable the refinement of an intervention program which will focus on strengthening ART adherence among rural WLA.

Setting The poor patient adherence in tuberculosis (TB) treatment is considered to be one of the most serious challenges which reflect the decrease of treatment success and emerging of the Multidrug Resistance-TB (MDR-TB). To our knowledge, the data about patients' adherence to anti-TB treatment in our country are missing. Objective This study was aimed to investigate the anti-TB treatment adherence rate and to identify factors related to eventual nonadherence among Kosovo TB patients. Design This study was conducted during 12 months, and the survey was a descriptive study using the standardized questionnaires with total 324 patients. Results The overall nonadherence for TB patient cohort was 14.5%, 95% CI (0.109–0.188). Age and place of residence are shown to have an effect on treatment adherence. Moreover, the knowledge of the treatment prognosis, daily dosage, side effects, and length of treatment also play a role. This was also reflected in knowledge regarding compliance with regular administration of TB drugs, satisfaction with the treatment, interruption of TB therapy, and the professional monitoring in the administration of TB drugs. Conclusion The level of nonadherence TB treatment in Kosovar patients is not satisfying, and more health care worker's commitments need to be addressed for improvement. PMID:29230326

To our knowledge, the data about patients' adherence to anti-TB treatment in our country are missing. This study was aimed to investigate the anti-TB treatment adherence rate and to identify factors related to eventual nonadherence among Kosovo TB patients. This study was conducted during 12 months, and the survey was a descriptive study using the standardized questionnaires with total 324 patients. The overall nonadherence for TB patient cohort was 14.5%, 95% CI (0.109-0.188). Age and place of residence are shown to have an effect on treatment adherence. Moreover, the knowledge of the treatment prognosis, daily dosage, side effects, and length of treatment also play a role. This was also reflected in knowledge regarding compliance with regular administration of TB drugs, satisfaction with the treatment, interruption of TB therapy, and the professional monitoring in the administration of TB drugs. The level of nonadherence TB treatment in Kosovar patients is not satisfying, and more health care worker's commitments need to be addressed for improvement.

Background Although web-based interventions for promoting health and health-related behavior can be effective, poor adherence is a common issue that needs to be addressed. Technology as a means to communicate the content in web-based interventions has been neglected in research. Indeed, technology is often seen as a black-box, a mere tool that has no effect or value and serves only as a vehicle to deliver intervention content. In this paper we examine technology from a holistic perspective. We see it as a vital and inseparable aspect of web-based interventions to help explain and understand adherence. Objective This study aims to review the literature on web-based health interventions to investigate whether intervention characteristics and persuasive design affect adherence to a web-based intervention. Methods We conducted a systematic review of studies into web-based health interventions. Per intervention, intervention characteristics, persuasive technology elements and adherence were coded. We performed a multiple regression analysis to investigate whether these variables could predict adherence. Results We included 101 articles on 83 interventions. The typical web-based intervention is meant to be used once a week, is modular in set-up, is updated once a week, lasts for 10 weeks, includes interaction with the system and a counselor and peers on the web, includes some persuasive technology elements, and about 50% of the participants adhere to the intervention. Regarding persuasive technology, we see that primary task support elements are most commonly employed (mean 2.9 out of a possible 7.0). Dialogue support and social support are less commonly employed (mean 1.5 and 1.2 out of a possible 7.0, respectively). When comparing the interventions of the different health care areas, we find significant differences in intended usage (p = .004), setup (p < .001), updates (p < .001), frequency of interaction with a counselor (p < .001), the system (p = .003) and peers (p

Background: Nonadherence to medication is a recognized problem and may be the most challenging aspect of treatment. Methods: We performed a systematic review of factors that influence adherence and the consequences of nonadherence to the patient, healthcare system and society, in patients with schizophrenia. Particular attention was given to the effect of nonadherence on hospitalization rates, as a key driver of increased costs of care. A qualitative systematic literature review was conducted using a broad search strategy using disease and adherence terms. Due to the large number of abstracts identified, article selection was based on studies with larger sample sizes published after 2001. Thirty-seven full papers were included: 15 studies on drivers and 22 on consequences, of which 12 assessed the link between nonadherence and hospitalization. Results: Key drivers of nonadherence included lack of insight, medication beliefs and substance abuse. Key consequences of nonadherence included greater risk of relapse, hospitalization and suicide. Factors positively related to adherence were a good therapeutic relationship with physician and perception of benefits of medication. The most frequently reported driver and consequence were lack of insight and greater risk of hospitalization respectively. Conclusions: Improving adherence in schizophrenia may have a considerable positive impact on patients and society. This can be achieved by focusing on the identified multitude of factors driving nonadherence. PMID:24167693

Adherence to drug treatment is key to successful therapeutic intervention, especially in chronic conditions. This holds particularly true in the setting of cardiovascular diseases, because poor adherence may have serious adverse effects in terms of morbidity and mortality. Many factors may contribute to poor adherence, which can be either patient-related or dependent on the healthcare system, the physician and the environment. The identification and appropriate correction of these factors may result in both clinical and economic benefits. In this setting it is also important to assess the implications of the increasing use of generic or equivalent drugs on adherence to pharmacological therapy. This topic has recently been addressed by an important Expert Consensus Document, endorsed by the Italian Societies of Cardiovascular Disease and Prevention, which was published in the Giornale Italiano di Cardiologia. The document addressed the relevance of the problem, potential determinants and possible solutions.

Branched-chain amino acids (BCAA) are valuable in the treatment of liver cirrhosis because they increase serum albumin levels. Poor adherence to BCAA may adversely affect prognosis, but little is known about factors predicting adherence. We undertook a survey of patients prescribed BCAA for the treatment of cirrhosis. Pharmacists carried out face-to-face interviews with patients (or their representatives) prescribed any of nine BCAA formulations. Question categories included patient characteristics, prescription of BCAA granules, and perceptions of BCAA administration, including adherence and possible factors that might impact adherence. "Poor adherence" was defined as "not taking the medication appropriately" or "forgetting to take the medication". Overall, 253 patients (or representatives) completed the survey, of whom 135 were men, 114 were women, and 148 were ≥70 years old. Most patients (163) were prescribed BCAA for ≥2 years and were using three packs per day. Thirty-two patients did not take their medication appropriately and 69 sometimes forgot to administer it. Weariness of taking the medication (P < 0.001) and the perceived unpleasantness (P = 0.023) of the medication in terms of its taste and volume were significantly associated with poor adherence. The patients reported that the most influential educators were general practitioners, followed by certified hepatologists, then pharmacists. Most patients had good adherence to BCAA in clinical practice. Poor adherence was associated with weariness with taking medication, and the unpleasantness of the medication itself. Patient education from general practitioners and hepatologists combined with adherence counseling from pharmacists may help improve adherence. © 2016 The Authors.

Self-report is considered most suitable to measure medication adherence in routine clinical practice. However, accuracy of self-report as a quantitative measure of adherence is not well documented. To assess the accuracy of a self-report measure of adherence (Medication Adherence Report Scale [MARS-5]) for identifying nonadherent users of inhalation medication among patients with chronic obstructive pulmonary disease (COPD), compared with medication refill adherence (MRA) as reference. We used baseline data from the Pharmaceutical Care for Patients with COPD (PHARMACOP)-trial (n = 734). Patients with incomplete MARS-5 and/or incomplete pharmacy refill records were excluded (n = 121). Internal consistency of MARS-5 (Crohnbach α) and Spearman rank correlation (ρ) with MRA were calculated. Different thresholds for nonadherence were used to calculate sensitivity, specificity, and positive predictive value (PPV), compared with dichotomized MRA (MRA ≥80% = adherent). A receiver operating characteristic (ROC) curve was plotted to determine the goodness of test. 613 patients were included in the analysis. The mean adherence score by MARS-5 (range = 5-25) was 23.5 (SD = 2.6); mean adherence by MRA was 83.4% (SD = 23.8%). Internal consistency of MARS-5 was high (α = 0.77). Continuous MARS-5 scores correlated poorly with continuous MRA scores (ρ = 0.10; P = 0.011). When lowering the nonadherence threshold stepwise from 25 to 20, MARS-5 did not reach sufficient sensitivity (53% to 13%), specificity (57% to 94%), and PPV (42% to 57%) to detect nonadherers compared with dichotomized MRA. ROC curve plotting resulted in an area under the curve value of 0.56 (95% CI = 0.521-0.616; P = 0.005). Self-reported adherence measured by MARS-5 is inaccurate in identifying nonadherence to inhalation medication in patients with COPD.

Exercise classes provide a range of benefits for older adults, but adherence levels are poor. We know little of instructors' experiences of delivering exercise classes to older adults. Semistructured interviews, informed by the Theory of Planned Behavior (TPB), were conducted with instructors (n = 19) delivering multicomponent exercise classes to establish their perspectives on older adults' uptake and adherence to exercise classes. Analysis revealed 'barriers' to uptake related to identity, choice/control, cost, and venue, and 'solutions' included providing choice/control, relating exercise to identity, a personal touch, and social support. Barriers to adherence included unrealistic expectations and social influences, and solutions identified were encouraging commitment, creating social cohesion, and an emphasis on achieving outcomes. Older adults' attitudes were an underlying theme, which related to all barriers and solutions. The instructor plays an important, but not isolated, role in older adults' uptake and adherence to classes. Instructors' perspectives help us to further understand how we can design successful exercise classes.

Hundreds of millions of people worldwide have asthma and COPD. Current medications to control these chronic respiratory diseases can be administered using inhaler devices, such as the pressurized metered dose inhaler and the dry powder inhaler. Provided that they are used as prescribed, inhalers can improve patient clinical outcomes and quality of life. Poor patient inhaler adherence (both time of use and user technique) is, however, a major clinical concern and is associated with poor disease control, increased hospital admissions, and increased mortality rates, particularly in low- and middle-income countries. There are currently limited methods available to health-care professionals to objectively and remotely monitor patient inhaler adherence. This review describes recent sensor-based technologies that use audio-based approaches that show promising opportunities for monitoring inhaler adherence in clinical practice. This review discusses how one form of sensor-based technology, audio-based monitoring systems, can provide clinically pertinent information regarding patient inhaler use over the course of treatment. Audio-based monitoring can provide health-care professionals with quantitative measurements of the drug delivery of inhalers, signifying a clear clinical advantage over other methods of assessment. Furthermore, objective audio-based adherence measures can improve the predictability of patient outcomes to treatment compared with current standard methods of adherence assessment used in clinical practice. Objective feedback on patient inhaler adherence can be used to personalize treatment to the patient, which may enhance precision medicine in the treatment of chronic respiratory diseases.

Poor adherence to risk factor management behaviors for coronary heart disease (CHD) patients increases the risk for a further cardiac event. There is a scarcity of literature about the level of adherence to risk factor management behaviors after CHD diagnosis in Jordan. The aim of this study was to explore which demographic, psychosocial, and clinical factors predict better adherence to risk factor management behaviors, particularly smoking cessation, physical activity, healthy diet, and medication adherence. In addition, we sought to explore the association of poor adherence to hospital readmission. A cross-sectional survey was performed using a sample of 350 patients who visited the outpatient clinics in 4 hospitals in Jordan. Data were obtained from 254 patients (response rate, 73%). Most were overweight (47.8%) or obese (28.5%), and 30% remained smokers after CHD diagnosis; 53 (21.5%) described themselves as ex-smokers. One-third of participants (88, 34.8%) performed regular walking exercise. Only 16% of participants reported that they had been instructed to perform regular activity. Stepwise multiple regressions revealed younger age and lower body mass index as independent predictors for more physical activity. Only 51 (20.9%) reported always following a low-fat dietary regimen, and participants who received dietary recommendation advice were significantly more likely to be on a healthy diet (odds ratio, 10.3; 95% confidence interval, 3.79-30.80; P < .001). Most of the participants (183, 72%) reported low medication adherence (score ≤6), based on the Morisky scale, and only 5 (2%) reported a high adherence score (score = 8). Male gender and having chronic back pain were independent predictors for better medication adherence. About one-third of participants had been hospitalized for cardiac reason at last 2 times in the past 12 months. Rehospitalization was significantly more common among patients who were not following a dietary regimen (Mann-Whitney Z = -2

Improving outpatient primary medication adherence with physician guided, automated dispensing

Background Physician dispensing, different from pharmacist dispensing, is a way for practitioners to supply their patients with medications, at the point of care. The InstyMeds dispenser and logistics system can automate much of the dispensing, insurance adjudication, inventory management, and regulatory reporting that is required of physician dispensing. Objective To understand the percentage of patients that exhibit primary adherence to medication in the outpatient setting when choosing InstyMeds. Method The InstyMeds dispensing database was de-identified and analyzed for primary adherence. This is the ratio of patients who dispensed their medication to those who received an eligible prescription. Results The average InstyMeds emergency department installation has a primary adherence rate of 91.7%. The maximum rate for an installed device was 98.5%. Conclusion Although national rates of primary adherence have been found to be in the range of 70%, automated physician dispensing vastly improves the rate of adherence. Improved adherence should lead to better patient outcomes, fewer return visits, and lower healthcare costs. PMID:28115860

failure (IRR 0.55, 95%CI 0.44-0.69 p<0.001). Drug toxicity and stigma-related barriers were significantly associated with virological failure, while forgetfulness was not associated with virological failure. Our study highlights the overall high level of medication adherence among individuals initiating ART within the Indian national program. Primary factors contributing towards poor adherence and subsequent virological failure in the proportion of individuals with poor adherence included drug toxicity, perceived stigma and poor access to health care services. Strategies that may contribute towards improved adherence include minimizing drug interruptions for medical reasons, use of newer ART regimens with better safety profiles and increasing access with more link ART centers that decentralize ART dispensing systems to individuals.

Treatment adherence in cystic fibrosis (CF) is often poor, however, less is known about adherence to pancreatic enzymes, a critical component of the CF treatment regimen. Parent caregivers often report elevations in depression, and parental depression may adversely affect children's adherence. This prospective study evaluated adherence to pancreatic enzymes in 83 patients (1-13 years) . Adherence was measured across 3 months with electronic pill-caps . Weight was measured at baseline and a 3-month follow-up. Parental depressive symptoms were evaluated by using the Center for Epidemiologic Studies Depression Scale (CES-D). Adherence to pancreatic enzymes was 49.4% ± 3.4%. Adherence was higher at school (94.4% ± 6.1%) than at home (42.3% ± 3.1%), and higher for toddlers (50.6% ± 5.2%) than for school-aged children (37.5% ± 3.7%). Parents reported high rates of depressive symptoms (30% in the clinical range, 18% with moderate symptoms). Children of parents with symptoms of depression versus those without were less adherent (34.8% ± 4.5% vs 48.5% ± 4.1%), and adherence to enzymes was significantly related to 3-month weight outcomes. Average gain in weight z scores across 3 months was 0.5 ± 0.2for children who were >50% adherent and -0.1 ± 6.1for children who were <33% adherent. Parental depression had a signifcant, indirect effect on weight via adherence (-0.005 ± 0.003 gain in weight z score per CES-D unit ). High rates of parental depressive symptoms, coupled with its negative effects on adherence, suggest that measuring and treating parental depression may improve children's adherence to therapy.

Objectives To provide an overview of medication adherence, discuss the potential for smartphone medication adherence applications (adherence apps) to improve medication nonadherence, evaluate features of adherence apps across operating systems (OSs), and identify future opportunities and barriers facing adherence apps. Practice description Medication nonadherence is a common, complex, and costly problem that contributes to poor treatment outcomes and consumes health care resources. Nonadherence is difficult to measure precisely, and interventions to mitigate it have been largely unsuccessful. Practice innovation Using smartphone adherence apps represents a novel approach to improving adherence. This readily available technology offers many features that can be designed to help patients and health care providers improve medication-taking behavior. Main outcome measures Currently available apps were identified from the three main smartphone OSs (Apple, Android, and Blackberry). In addition, desirable features for adherence apps were identified and ranked by perceived importance to user desirability using a three-point rating system: 1, modest; 2, moderate; or 3, high. The 10 highest-rated apps were installed and subjected to user testing to assess app attributes using a standard medication regimen. Results 160 adherence apps were identified and ranked. These apps were most prevalent for the Android OS. Adherence apps with advanced functionality were more prevalent on the Apple iPhone OS. Among all apps, MyMedSchedule, MyMeds, and RxmindMe rated the highest because of their basic medication reminder features coupled with their enhanced levels of functionality. Conclusion Despite being untested, medication apps represent a possible strategy that pharmacists can recommend to nonadherent patients and incorporate into their practice. PMID:23571625

2018-01-01

Background A new Lebanese scale measuring medication adherence considered socioeconomic and cultural factors not taken into account by the eight-item Morisky Medication Adherence Scale (MMAS-8). Objectives were to validate the new adherence scale and its prediction of hypertension control, compared to MMAS-8, and to assess adherence rates and factors. Methodology A cross-sectional study, including 405 patients, was performed in outpatient cardiology clinics of three hospitals in Beirut. Blood pressure was measured, a questionnaire filled, and sodium intake estimated by a urine test. Logistic regression defined predictors of hypertension control and adherence. Results 54.9% had controlled hypertension. 82.4% were adherent by the new scale, which showed good internal consistency, adequate questions (KMO coefficient = 0.743), and four factors. It predicted hypertension control (OR = 1.217; p value = 0.003), unlike MMAS-8, but the scores were correlated (ICC average measure = 0.651; p value < 0.001). Stress and smoking predicted nonadherence. Conclusion This study elaborated a validated, practical, and useful tool measuring adherence to medications in Lebanese hypertensive patients.

Prevalence, predictors, and clinical consequences of medical adherence in IBD: How to improve it?

PubMed Central

Lakatos, Peter Laszlo

2009-01-01

Inflammatory bowel diseases (IBD) are chronic diseases with a relapsing-remitting disease course necessitating lifelong treatment. However, non-adherence has been reported in over 40% of patients, especially those in remission taking maintenance therapies for IBD. The economical impact of non-adherence to medical therapy including absenteeism, hospitalization risk, and the health care costs in chronic conditions, is enormous. The causes of medication non-adherence are complex, where the patient-doctor relationship, treatment regimen, and other disease-related factors play key roles. Moreover, subjective assessment might underestimate adherence. Poor adherence may result in more frequent relapses, a disabling disease course, in ulcerative colitis, and an increased risk for colorectal cancer. Improving medication adherence in patients is an important challenge for physicians. Understanding the different patient types, the reasons given by patients for non-adherence, simpler and more convenient dosage regimens, dynamic communication within the health care team, a self-management package incorporating enhanced patient education and physician-patient interaction, and identifying the predictors of non-adherence will help devise suitable plans to optimize patient adherence. This editorial summarizes the available literature on frequency, predictors, clinical consequences, and strategies for improving medical adherence in patients with IBD. PMID:19750566

To investigate changes in inhaled corticosteroids adherence, both before and after a scheduled follow-up visit, in young children in a comprehensive asthma management program. One-year prospective follow-up study in 104 asthmatic children (mean age 4.8 years). Adherence to inhaled corticosteroids was assessed using electronic (Smartinhaler®) devices. We assessed changes in adherence before and after clinic visits. A  > 10% increase in adherence in the 3 days preceding a clinic visit was considered to reflect clinically relevant white coat adherence (WCA) if it exceeded background variation in adherence (median change >0, and increase larger than adherence changes after a clinic visit). Overall adherence was high (median 85%). A pre-visit increase in adherence of >10% was demonstrated in 17 patients (22%), but the median change in adherence around a clinic visit was 0. There were no significant differences in changes in adherence between the days before or after a visit (P > 0.2). The median coefficient of variation in adherence was 9%, and did not significantly differ between children with and without a pre-visit increase in adherence (P = 0.12). Twelve patients (15.4%) showed an increase of adherence in the month following a clinic visit; their overall mean (SE) adherence was slightly lower (73% (4.6%)) than those without such an increase (80% (2.2%), P = 0.054). There was no WCA in children with asthma enrolled in a comprehensive asthma management program with high overall adherence. This suggests that WCA in pediatric chronic conditions primarily occurs against the background of low overall adherence. © 2014 Wiley Periodicals, Inc.

This study aimed to evaluate prevalence of prescription of and adherence to selective serotonin reuptake inhibitors (SSRIs) and serotonin-norepinephrine reuptake inhibitors (SNRIs) and whether adherence to these classes of drugs affects overall medication adherence in older persons. In a cross-sectional analysis of administrative data comprehensive of all prescribed drugs reimbursed by the Italian national health care system, new prescriptions of SSRIs and SNRIs to persons aged 65 years or older were analyzed (n = 380,400 in 2011; 395,806 in 2012; 409,741 in 2013, from a total sample of 3,762,299 persons aged 65 years or older) as well as prescriptions of antihypertensives, statins, other psychiatric drugs, antidiabetics, antiplatelets, anticoagulants, drugs for chronic obstructive pulmonary disease, and antiosteoporotics. Adherence was estimated by calculating the proportion of days covered by drugs dispensed during a period of 365 days. Adherence was defined as a proportion of days covered of more than 80%. Prevalence of SSRI and SNRI prescriptions varied from 11.4% in 2011 to 12.1% in 2013. Adherence to SSRI and SNRI prescriptions ranged from 31.2% in persons aged ≥ 95 years in 2011 to 41.8% in persons aged 75-84 years in 2013. Persons adherent to SSRI and SNRI prescriptions were more likely to be adherent to the other medications, after adjustment for age, gender, and number of drugs prescribed. The highest association was found for adherence to psychiatric drugs (OR = 1.9; 95% CI, 1.8-2.0). Adherence to SSRI and SNRI prescriptions is poor in older persons. However, people adherent to these classes of antidepressants are more likely to be adherent to the other medications they are prescribed. Studies are needed to evaluate the reasons for and the potential benefits of increasing adherence to antidepressants on overall adherence. © Copyright 2016 Physicians Postgraduate Press, Inc.

The objective of this study is to investigate the adherence and the factors that influence adherence to physical activity in adults with dyslipidemia, hypertension, or diabetes. The analyses were based on data collected at the baseline of the 14,521 participants from the study ELSA-Brasil aged between 35 and 74 years. The level of leisure time physical activity was determined using the International Physical Activity Questionnaire. Logistic regression analyses were performed to examine the influence of the demographic data, socioeconomic conditions, perceived health status, and access to exercise facilities in the neighborhood on adherence to physical activity. Men with hypertension and dyslipidemia were more active than women. The results show that 17.8%, 15.1%, and 13.9% of the subjects who reported dyslipidemia, hypertension, and diabetes, respectively, adhere to the physical activity recommendations. The factors positively associated with adherence were higher education and income. Older individuals who reported poor perceived health, were overweight and obese, regularly smoked, and had fewer opportunities to exercise in the neighborhood presented lower adherence. The number of adults with dyslipidemia, hypertension, and diabetes who adhere to the physical activity recommendations is very low. Higher education and income are positively associated with adherence, while age, excess body weight, negative perceived health, regular smoking, and lack of opportunity to exercise in the neighborhood were considered barriers to physical activity.

Optimizing Patient Management and Adherence for Children Receiving Growth Hormone.

2017-01-01

Poor adherence with growth hormone (GH) therapy has been associated with worse clinical outcomes, which in children relates specifically to their linear growth and loss of quality of life. The "360° GH in Europe" meeting, held in Lisbon, Portugal, in June 2016 and funded by Merck KGaA (Germany), examined many aspects of GH diseases. The three sessions, entitled " Short Stature Diagnosis and Referral ," " Optimizing Patient Management ," and " Managing Transition ," each benefited from three guest speaker presentations, followed by an open discussion and are reported as a manuscript, authored by the speakers. Reported here is a summary of the proceedings of the second session, which reviewed the determinants of GH therapy response, factors affecting GH therapy adherence and the development of innovative technologies to improve GH treatment in children. Response to GH therapy varies widely, particularly in regard to the underlying diagnosis, although there is little consensus on the definition of a poor response. If the growth response is seen to be less than expected, the possible reasons should be discussed with patients and their parents, including compliance with the therapy regimen. Understanding and addressing the multiple factors that influence adherence, in order to optimize GH therapy, requires a multi-disciplinary approach. Because therapy continues over many years, various healthcare professionals will be involved at different periods of the patient's journey. The role of the injection device for GH therapy, frequent monitoring of response, and patient support are all important for maintaining adherence. New injection devices are incorporating electronic technologies for automated monitoring and recording of clinically relevant information on injections. Study results are indicating that such devices can at least maintain GH adherence; however, acceptance of novel devices needs to be assessed and there remains an on-going need for innovations.

We sought to understand the association of specific aspects of care satisfaction, such as patients' perceived relationship with their psychiatrist and access to their psychiatrist and staff, and therapeutic alliance with participants' likelihood to adhere to their medication regimens among patients with bipolar disorder. We examined data from the multicenter Systematic Treatment Enhancement Program for Bipolar Disorder, an effectiveness study investigating the course and treatment of bipolar disorder. We expected that participants (n = 3037) with positive perceptions of their relationship with their psychiatrist and quality of psychopharmacologic care, as assessed by the Helping Alliance Questionnaire and Care Satisfaction Questionnaire, would be associated with better medication adherence. We utilized logistic regression models controlling for already established factors associated with poor adherence. Patients' perceptions of collaboration, empathy, and accessibility were significantly associated with adherence to treatment in individuals with bipolar disorder completing at least 1 assessment. Patients' perceptions of their psychiatrists' experience, as well as of their degree of discussing medication risks and benefits, were not associated with medication adherence. Patients' perceived therapeutic alliance and treatment environment impact their adherence to pharmacotherapy recommendations. This study may enable psychopharmacologists' practices to be structured to maximize features associated with greater medication adherence.

Background: Intimate partner violence (IPV) is associated with higher HIV incidence, reduced condom use, and poor adherence to antiretroviral therapy and other medications. IPV may also affect adherence to pre-exposure prophylaxis (PrEP). Methods: We analyzed data from 1785 HIV-uninfected women enrolled in a clinical trial of PrEP among African HIV serodiscordant couples. Experience of verbal, physical, or economic IPV was assessed at monthly visits by face-to-face interviews. Low PrEP adherence was defined as clinic-based pill count coverage <80% or plasma tenofovir levels <40 ng/mL. The association between IPV and low adherence was analyzed using generalized estimating equations, adjusting for potential confounders. In-depth interview transcripts were examined to explain how IPV could impact adherence. Results: Sixteen percent of women reported IPV during a median of 34.8 months of follow-up (interquartile range 27.0–35.0). Overall, 7% of visits had pill count coverage <80%, and 32% had plasma tenofovir <40 ng/mL. Women reporting IPV in the past 3 months had increased risk of low adherence by pill count (adjusted risk ratio 1.49, 95% confidence interval: 1.17 to 1.89) and by plasma tenofovir (adjusted risk ratio 1.51, 95% confidence interval: 1.06 to 2.15). Verbal, economic, and physical IPV were all associated with low adherence. However, the impact of IPV diminished and was not statistically significant 3 months after the reported exposure. In qualitative interviews, women identified several ways in which IPV affected adherence, including stress and forgetting, leaving home without pills, and partners throwing pills away. Conclusions: Women who reported recent IPV in the Partners PrEP Study were at increased risk of low PrEP adherence. Strategies to mitigate PrEP nonadherence in the context of IPV should be evaluated.

Treatment adherence and health outcomes in patients with bronchiectasis

PubMed Central

2014-01-01

Background We aimed to determine adherence to inhaled antibiotics, other respiratory medicines and airway clearance and to determine the association between adherence to these treatments and health outcomes (pulmonary exacerbations, lung function and Quality of Life Questionnaire-Bronchiectasis [QOL-B]) in bronchiectasis after 12 months. Methods Patients with bronchiectasis prescribed inhaled antibiotics for Pseudomonas aeruginosa infection were recruited into a one-year study. Participants were categorised as “adherent” to medication (medication possession ratio ≥80% using prescription data) or airway clearance (score ≥80% in the Modified Self-Reported Medication-Taking Scale). Pulmonary exacerbations were defined as treatment with a new course of oral or intravenous antibiotics over the one-year study. Spirometry and QOL-B were completed at baseline and 12 months. Associations between adherence to treatment and pulmonary exacerbations, lung function and QOL-B were determined by regression analyses. Results Seventy-five participants were recruited. Thirty-five (53%), 39 (53%) and 31 (41%) participants were adherent to inhaled antibiotics, other respiratory medicines, and airway clearance, respectively. Twelve (16%) participants were adherent to all treatments. Participants who were adherent to inhaled antibiotics had significantly fewer exacerbations compared to non-adherent participants (2.6 vs 4, p = 0.00) and adherence to inhaled antibiotics was independently associated with having fewer pulmonary exacerbations (regression co-efficient = -0.51, 95% CI [-0.81,-0.21], p < 0.001). Adherence to airway clearance was associated with lower QOL-B Treatment Burden (regression co-efficient = -15.46, 95% CI [-26.54, -4.37], p < 0.01) and Respiratory Symptoms domain scores (regression co-efficient = -10.77, 95% CI [-21.45; -0.09], p < 0.05). There were no associations between adherence to other respiratory medicines and any of the

Rethinking adherence.

In 2012, the Centers for Medicare & Medicaid Services (CMS) will introduce measures of adherence to oral hypoglycemic, antihypertensive, and cholesterol-lowering drugs into its Medicare Advantage quality program. To meet these quality goals, delivery systems will need to develop and disseminate strategies to improve adherence. The design of adherence interventions has too often been guided by the mistaken assumptions that adherence is a single behavior that can be predicted from readily available patient characteristics and that individual clinicians alone can improve adherence at the population level.Effective interventions require recognition that adherence is a set of interacting behaviors influenced by individual, social, and environmental forces; adherence interventions must be broadly based, rather than targeted to specific population subgroups; and counseling with a trusted clinician needs to be complemented by outreach interventions and removal of structural and organizational barriers. To achieve the adherence goals set by CMS, front-line clinicians, interdisciplinary teams, organizational leaders, and policymakers will need to coordinate efforts in ways that exemplify the underlying principles of health care reform.

Patients' mental models and adherence to outpatient physical therapy home exercise programs.

PubMed

Rizzo, Jon

2015-05-01

Within physical therapy, patient adherence usually relates to attending appointments, following advice, and/or undertaking prescribed exercise. Similar to findings for general medical adherence, patient adherence to physical therapy home exercise programs (HEP) is estimated between 35 and 72%. Adherence to HEPs is a multifactorial and poorly understood phenomenon, with no consensus regarding a common theoretical framework that best guides empirical or clinical efforts. Mental models, a construct used to explain behavior and decision-making in the social sciences, may serve as this framework. Mental models comprise an individual's tacit thoughts about how the world works. They include assumptions about new experiences and expectations for the future based on implicit comparisons between current and past experiences. Mental models play an important role in decision-making and guiding actions. This professional theoretical article discusses empirical research demonstrating relationships among mental models, prior experience, and adherence decisions in medical and physical therapy contexts. Specific issues related to mental models and physical therapy patient adherence are discussed, including the importance of articulation of patients' mental models, assessment of patients' mental models that relate to exercise program adherence, discrepancy between patient and provider mental models, and revision of patients' mental models in ways that enhance adherence. The article concludes with practical implications for physical therapists and recommendations for further research to better understand the role of mental models in physical therapy patient adherence behavior.

BACKGROUND AND OBJECTIVE: Health care provider adherence to asthma guidelines is poor. The objective of this study was to assess the effect of interventions to improve health care providers’ adherence to asthma guidelines on health care process and clinical outcomes. METHODS: Data sources included Medline, Embase, Cochrane CENTRAL Register of Controlled Trials, Cumulative Index to Nursing and Allied Health Literature, Educational Resources Information Center, PsycINFO, and Research and Development Resource Base in Continuing Medical Education up to July 2012. Paired investigators independently assessed study eligibility. Investigators abstracted data sequentially and independently graded the evidence. RESULTS: Sixty-eight eligible studies were classified by intervention: decision support, organizational change, feedback and audit, clinical pharmacy support, education only, quality improvement/pay-for-performance, multicomponent, and information only. Half were randomized trials (n = 35). There was moderate evidence for increased prescriptions of controller medications for decision support, feedback and audit, and clinical pharmacy support and low-grade evidence for organizational change and multicomponent interventions. Moderate evidence supports the use of decision support and clinical pharmacy interventions to increase provision of patient self-education/asthma action plans. Moderate evidence supports use of decision support tools to reduce emergency department visits, and low-grade evidence suggests there is no benefit for this outcome with organizational change, education only, and quality improvement/pay-for-performance. CONCLUSIONS: Decision support tools, feedback and audit, and clinical pharmacy support were most likely to improve provider adherence to asthma guidelines, as measured through health care process outcomes. There is a need to evaluate health care provider-targeted interventions with standardized outcomes. PMID:23979092

Social and psychological barriers to the disclosure of one's seropositive HIV status to significant others and poor adherence to taking medications pose significant challenges to the scaling-up of access to antiretroviral treatment (ART) in the workplace. Such barriers are predictive of sub-optimal treatment outcomes and bedevil HIV-prevention interventions at a societal level. Against this background, this article explores the lived experiences of 19 HIV-positive male participants, between the ages of 33 and 57 years, who were enrolled in an ART programme managed at an occupational health clinic at a mining company in South Africa. The majority of these mineworkers had been aware of their HIV status for between 5 and 7 years. The study explored psychological and relational factors, as aspects of these participants lived experiences, which had a bearing on their adherence to their ART regimen and the disclosure choices that they made regarding their HIV status. In our sample, those participants who were adherent demonstrated higher levels of control and acceptance of their HIV infection and were more confident in their ability to manage their treatment, while the group who were non-adherent presented with lower levels of adherence motivation and self-efficacy, difficulties in maintaining a healthy lifestyle and significant challenges in maintaining control over their lives. While most of the men favoured disclosing their HIV status to their partners for the sake of treatment support, they were less sure about disclosing to family members and non-family members, respectively, because of their need to protect these persons and due to their fear of being stigmatised. It was evident that treatment adherence choices and behaviours were impacted by psychological and relational factors, including disclosure decisions. We conclude with a bivariate model for understanding the adherence behaviours that influenced different patterns of ART adherence among the sample, and

Toward an information-motivation-behavioral skills model of microbicide adherence in clinical trials.

Unless optimal adherence in microbicide clinical trials is ensured, an efficacious microbicide may be rejected after trial completion, or development of a promising microbicide may be stopped, because low adherence rates create the illusion of poor efficacy. We provide a framework with which to conceptualize and improve microbicide adherence in clinical trials, supported by a critical review of the empirical literature. The information-motivation-behavioral skills (IMB) model of microbicide adherence conceptualizes microbicide adherence in clinical trials and highlights factors that can be addressed in behavioral interventions to increase adherence in such trials. This model asserts that microbicide adherence-related information, motivation, and behavioral skills are fundamental determinants of adherent microbicide utilization. Specifically, information consists of objective facts about microbicide use (e.g., administration and dosage) as well as heuristics that facilitate use (e.g., microbicides must be used with all partners). Motivation to adhere consists of attitudes toward personal use of microbicides (e.g., evaluating the consequences of using microbicides as good or pleasant) as well as social norms that support their use (e.g., beliefs that a sexual partner approves use of microbicides). Behavioral skills consist of objective skills necessary for microbicide adherence (e.g., the ability to apply the microbicide correctly and consistently). Empirical evidence concerning microbicide acceptability and adherence to spermicides, medication, and condom use regimens support the utility of this model for understanding and promoting microbicide adherence in clinical trials.

Patients with gastrointestinal (GI) risk factors who take non-steroidal anti-inflammatory drugs (NSAIDs) should also take gastroprotective agents (GPAs). No studies have evaluated adherence and reasons for non-adherence to GPA and NSAID therapies. This was a prospective, multicenter, observational, longitudinal study. Patients attending rheumatology/orthopedic clinics who were co-prescribed NSAID plus GPA for at least 15 days and had risk factors for GI complications were followed up by telephone call. Optimal adherence was defined as taking the drug for ≥ 80% of prescribed days. Multivariate logistic regression analysis was used to determine factors associated with non-adherence. Of 1,232 patients interviewed, 192 were excluded because of inaccurate data. Of the remaining 1,040 patients, 74 % were prescribed low-dose NSAIDs and 99.8 % were prescribed a standard or high-dose GPA. In all, 70 % of NSAIDs and 63.1 % of GPA prescriptions were short term (< 30 days). The majority of patients who were prescribed either an NSAID (92.5 % ) or GPA (85.9 % ) started therapy. Optimal adherence to GPA or NSAIDs was reported by 79.7 % (95 % confidence interval (CI): 76.9-82.2 % ) and 84.1 % (95 % CI: 81.7-86.3 % ) of patients, respectively. More adverse events occurred among patients who reported non-optimal adherence than among patients with optimal adherence to GPA (22.1 vs. 1.9 % , P < 0.0001). As reasons for non-adherence, patients most frequently cited infrequent/low-intensity rheumatic pain (NSAIDs) or forgetfulness (GPAs). Adverse events and short-term treatment were independent factors associated with poor adherence for both NSAIDs and GPAs. History of uncomplicated peptic ulcer and frequent dosing were additional factors associated with non-adherence to NSAIDs. Most frequent reasons for non-adherence are infrequent/low-intensity rheumatic pain (NSAIDs) or forgetfulness (GPAs). Short-term treatment and adverse events were associated with poor adherence for both

Background Treatment continuity is a major challenge in the long-term management of patients with schizophrenia; poor patient adherence to antipsychotic drugs has been associated with negative clinical outcomes. Long-acting injectable therapies may improve adherence and lessen the risk for psychiatric-related relapse, often leading to rehospitalization and higher healthcare costs. Therefore, understanding the determinants of adherence to antipsychotics is critical in the management of patients with schizophrenia. Objective To assess the impact of baseline patient characteristics on adherence as measured by the Healthcare Effectiveness Data and Information Set (HEDIS) measure of continuity of antipsychotic medications among patients with Medicaid coverage. Methods Medicaid healthcare claims data between 2008 and 2011 from 5 states were used to identify patients who were diagnosed with schizophrenia (aged 25–64 years) and received ≥1 antipsychotic prescriptions in baseline year 2010 and in measurement year 2011. The HEDIS continuity of antipsychotic medications (ie, adherence) measure was defined as the proportion of days covered with any antipsychotic medication ≥80% during the measurement year. The 2 cohorts compared paliperidone palmitate with any other antipsychotics, including quetiapine, risperidone, and haloperidol. The baseline-year characteristics were evaluated as potential predictive factors of adherence in the measurement year using multivariate logistic regressions. The regression models incorporated the inverse probability of treatment weights to control for differences in baseline characteristics between the paliperidone palmitate and the other antipsychotics cohort. Results Among the 12,990 patients who received an antipsychotic during the study period, 48.6% successfully achieved the continuity criteria in the measurement year. After controlling for other covariates, the odds of adherence were improved by adherence at baseline (odds ratio [OR

Background Poor adherence to anti-diabetic medications contributes to suboptimal glycaemic control in patients with type 2 diabetes (T2D). A range of interventions have been developed to promote anti-diabetic medication adherence. However, there has been very little focus on the characteristics of these interventions and how effectively they address factors that predict non-adherence. In this systematic review we assessed the characteristics of interventions that aimed to promote adherence to anti-diabetic medications. Method Using appropriate search terms in Medline, Embase, CINAHL, International Pharmaceutical Abstracts (IPA), PUBmed, and PsychINFO (years 2000–2013), we identified 52 studies which met the inclusion criteria. Results Forty-nine studies consisted of patient-level interventions, two provider-level interventions, and one consisted of both. Interventions were classified as educational (n = 7), behavioural (n = 3), affective, economic (n = 3) or multifaceted (a combination of the above; n = 40). One study consisted of two interventions. The review found that multifaceted interventions, addressing several non-adherence factors, were comparatively more effective in improving medication adherence and glycaemic target in patients with T2D than single strategies. However, interventions with similar components and those addressing similar non-adherence factors demonstrated mixed results, making it difficult to conclude on effective intervention strategies to promote adherence. Educational strategies have remained the most popular intervention strategy, followed by behavioural, with affective components becoming more common in recent years. Most of the interventions addressed patient-related (n = 35), condition-related (n = 31), and therapy-related (n = 20) factors as defined by the World Health Organization, while fewer addressed health care system (n = 5) and socio-economic-related factors (n = 13). Conclusion There is a noticeable shift in the literature

Children with obstructive sleep apnea are increasingly being treated with positive airway pressure (PAP), particularly if they have underlying medical conditions. Although PAP is an effective treatment, its use is challenging due to poor adherence. We hypothesized that demographic, psychosocial, and polysomnographic parameters would be related to PAP adherence. We therefore prospectively collected data potentially pertaining to PAP adherence, and correlated it with PAP use. Fifty-six patients and their parents completed a series of psychosocial questionnaires prior to PAP initiation. Objective adherence data were obtained after 1 and 3 months of PAP use. The population was primarily obese; 23% had neurodevelopmental disabilities. PAP adherence varied widely, with PAP being worn 22 ± 8 nights in month-1, but mean use was only 3 ± 3 h/night. The greatest predictor of use was maternal education (p = 0.002 for nights used; p = 0.033 for mean h used/night). Adherence was lower in African American children vs other races (p = 0.021). In the typically developing subgroup, adherence correlated inversely with age. Adherence did not correlate with severity of apnea, pressure levels, or psychosocial parameters other than a correlation between family social support and nights of PAP use in month-3. PAP adherence in children and adolescents is related primarily to family and demographic factors rather than severity of apnea or measures of psychosocial functioning. Further research is needed to determine the relative contributions of maternal education, socioeconomic status and cultural beliefs to PAP adherence in children, in order to develop better adherence programs.

A comprehensive review was performed to investigate the effect of route of administration on medication adherence and persistence in rheumatoid arthritis (RA) and to compare adherence/persistence with oral medications between RA and a non-painful disease (dyslipidemia). Comprehensive database searches were performed to identify studies investigating medication adherence and/or persistence in adults with RA receiving conventional synthetic or biologic agents. Similar searches were performed for studies of patients with dyslipidemia receiving statins. Studies had to be published after 1998 in English and involve ≥6 months' follow up. Adherence and persistence were compared between the different routes of drug administration in RA, and between the two diseases for oral medications. A total of 35 and 28 papers underwent data extraction for RA and dyslipidemia, respectively. Within the constraints of the analysis, adherence and persistence rates appeared broadly similar for the different routes of drug administration in RA. Adherence to oral medications was also broadly similar across the two diseases, but persistence was lower in dyslipidemia. Poor adherence has clinical consequences in both diseases: greater disease activity and risk of flare in RA, and increased serum cholesterol levels and risk of heart and cerebrovascular disease in dyslipidemia. Over 1-3 years, poor adherence to biologic RA medications led to increased resource use and medical costs but lower total direct costs due to reduced biologic drug costs. Conversely, poor adherence to dyslipidemia medications resulted in increased total direct costs. In both diseases, adherence improved with patient education/support. The route of drug administration and the symptomatic (pain) nature of the disease do not appear to be dominant factors for drug adherence or persistence in RA. The wide range of adherence and persistence values and definitions across studies made comparisons between drug formulations and

Can Mindfulness Training Improve Medication Adherence? Integrative Review of the Current Evidence and Proposed Conceptual Model.

PubMed

Salmoirago-Blotcher, Elena; Carey, Michael P

Medication adherence is a complex, multi-determined behavior that is often influenced by system- (e.g., cost), drug- (e.g., regimen complexity), and patient-related (e.g., depression) factors. System-level approaches (e.g., making medications more affordable) are critically important but do not address patient-level factors that can undermine adherence. In this paper, we identify patient-level determinants of non-adherence and discuss whether mindfulness-training approaches that target these determinants can help to improve adherence to medical treatment. We highlight two chronic medical conditions (viz., heart failure and HIV) where poor adherence is a significant concern, and examine the evidence regarding the use of mindfulness interventions to improve medication adherence in these two conditions. We also discuss the theoretical underpinnings of mindfulness training with respect to medication adherence, and conclude by suggesting directions for future research. Copyright © 2018 Elsevier Inc.

Poor treatment adherence is a major problem among individuals with chronic illness. Research indicates that adherence is worsened when accompanied by depressive symptoms. In this preliminary study, we aimed to describe how a patient-centered approach could be employed to aid patients with depressive symptoms in following their treatment regimens. The sample consisted of 14 patients undergoing antiretroviral therapy (ART) for HIV who reported clinically-significant depressive symptoms. Participant ratings of 23 treatment-related statements were examined using two assessment and analytic techniques. Interviews were conducted with participants to determine their views of information based on the technique. Results indicate that while participants with optimal adherence focused on views of treatment associated with side effects to a greater extent than participants with poor adherence, they tended to relate these side effects to sources of intrinsic motivation. The study provides examples of how practitioners could employ the assessment techniques outlined to better understand how patients think about treatment and aid them in effectively framing their health-related goals.

Adherence to highly active antiretroviral therapy (HAART) must be close to perfect in order to maintain suppression of HIV viral load, and to prevent the development of drug resistant strains of HIV. People living with HIV (PLWH) often report low levels of adherence. One variable that has been linked to poor adherence is perceived discrimination; however, research has generally not considered the possible unique effects of different types of discrimination on adherence. The present pilot study aimed to examine the association of three types of discrimination (due to HIV+ status, race, or sexual orientation) with adherence among 57 PLWH. Logistic regression analyses were conducted to demonstrate the relationships between each type of discrimination and self-reported adherence. Racial discrimination significantly predicted lower adherence levels, whereas sexual orientation- and HIV-related discrimination did not. Results underscore the importance of addressing discrimination issues, specifically racial, when designing interventions to improve adherence to HAART.

Resilience and religiosity have received attention as an important process in the experience and management of chronic comorbidities; however, there is no study evaluating resilience in hemodialysis patients and its association with other psychological dimensions or with treatment adherence. This observational prospective study assessed resilience (25 item Wagnild and Young Resilience Scale), religiosity under three dimensions (organizational, non-organizational and intrinsic) using DUREL scale, depressive symptoms (Patient Health Questionnaire-9) and health-related quality of life (Short Form-36 questionnaire). The main outcomes were medication adherence using the Morisky Medication Adherence Scale-8 (MMAR-8) and the missing/shortened dialysis sessions in the following six months. Of 208 patients approached, 202 (97.1%) agreed to participate. One hundred twenty-three patients (60.9%) were males and mean age was 52.8 ± 14.8 years-old. The median time on hemodialysis was 36 months (IQR, 12, 84). 82 (40.6%) patients obtained a MMAS-8 score <6 and were considered as having 'poor adherence'. Overall, the mean score of medication adherence was low (5.7 ± 2.1). About adherence to hemodialysis sessions, patients missed a total of 234 (1.6%) hemodialysis sessions. Forty-eight patients (23.7%) missed an average of at least three sessions in six months. Regarding adherence to medication, there was no association in the uni- or multivariate analysis between religiosity dimensions and MMAS-8 score. After adjustment, resilience was positively associated with MMAS-8 score (standardized β coefficient .239, p = .016). Organized and intrinsic religiosity were associated with adherence to dialysis sessions (standardized β coefficient .258, p = .004 and .231, p = .026, respectively). Interestingly, opposite to medication adherence, more resilient patients were associated with less adherence to hemodialysis sessions (standardized β coefficient -.296, p = .001

Poor adherence to a low-sodium diet (LSD) and prescribed medications increases rehospitalization risk in patients with heart failure (HF). Clinicians have difficulty assessing adherence objectively, so they depend on patients' self-report. The degree to which self-reported adherence reflects actual adherence is unclear. We examined patients' ability to self-monitor adherence to an LSD and medications by comparing self-reported adherence with objective evidence of adherence. A total of 133 patients with HF (male 71%; ejection fraction 35% +/- 14%) completed the Medical Outcomes Study Specific Adherence Scale. Adherence to the LSD and medication were assessed objectively using 24-hour urinary sodium excretion and dose counting with an electronic monitoring device, respectively. On the basis of self-report, patients were divided into adherent and non-adherent groups and evaluated for differences according to objective adherence. There were no differences in urinary sodium levels between the self-reported LSD adherent and non-adherent groups (4560 mg vs. 4333 mg; P = .59). Self-reported adherent and non-adherent medication groups took 92.4% and 80.4% of prescribed doses, respectively (P < .001). Patients were able to accurately estimate adherence to medication, but they failed to estimate LSD adherence. This finding suggests that we need to improve our means of evaluating adherence to the LSD and of educating patients more thoroughly about following the LSD. We speculated that the inability to estimate LSD adherence may be the result of gaps in patients' knowledge that preclude accurate self-assessment.

Background There are approximately 1,000,000 persons living with HIV/AIDS (PLH) in the United States; to reduce rates of new infection and curb disease progression, adherence to HIV medication among PLH is critical. Despite elevated trauma rates in PLH, no studies to date have investigated the relationship between dissociation, a specific symptom of trauma, and HIV medication adherence. We hypothesized that Post-Traumatic Stress Disorder (PTSD) symptoms would be associated with lower adherence, and that dissociation would moderate this relationship. Methods Forty-three individuals with HIV were recruited from community-based clinics to participate in a cross-sectional study. The relationship of trauma, dissociation, and their interaction to the probability of antiretroviral adherence was assessed using a hierarchical binary logistic regression analysis. Results Among 38 eligible participants, greater PTSD was associated with lower odds of adherence (OR = .92, p < .05). Dissociation moderated the effect of PTSD on adherence, resulting in lower odds of adherence (OR = .95, p < .05). PTSD symptoms were significantly associated with lower odds of adherence in individuals reporting high levels of dissociation (OR = .86, p < .05) but not in those reporting low levels of dissociation (OR = 1.02, p > .05). Conclusions This is the first study to demonstrate a relationship between dissociation and medication adherence. Findings are discussed in the context of clinical management of PLH with trauma histories and the need for interventions targeting dissociative symptomatology to optimize adherence. PMID:21636097

To examine the factors influencing adherence to urate-lowering therapy in patients with gout in Singapore. Gout is the most common type of chronic inflammatory arthritis. Urate-lowering therapy is used to treat gout by reducing serum uric acid levels. However, adherence to urate-lowering therapy among patients remains poor. To date, there have been no available studies based on a conceptual framework that examined factors influencing medication adherence in patients with gout. Cross-sectional, descriptive correlational study. A convenience sample of outpatients (n = 108) was recruited between October 2014-January 2015 from a tertiary hospital in Singapore. Outcomes were measured by relevant valid and reliable instruments. Descriptive statistics and parametric tests including multiple linear regression were used to analyse the data. Although 44.4% of the participants were high adherers to urate-lowering therapy, the mean adherence level was moderate. Significant differences in medication adherence scores were found among the subgroups of gender, ethnicity, marital status, employment status and presence of comorbidity. Medication adherence was positively significantly correlated with age, number of comorbidities and beliefs about medicines. Linear regression showed that higher level of beliefs about medicines, presence of comorbidity and being married were factors positively influencing medication adherence. This study revealed moderate adherence to urate-lowering therapy in patients with gout in Singapore, indicating the need for strategies to improve adherence by considering its main influencing factors. Future research should be conducted to develop interventions targeted at modifying patients' beliefs about medicines in order to improve medication adherence. Findings from this study allow healthcare providers to quickly and easily identify patients who may have low adherence. Nurses should take the lead in educating patients on the mechanism of urate

Background With the expansion of Medicaid and low-cost health insurance plans among diverse patient populations, objective measures of medication adherence using pharmacy claims could advance clinical care and translational research for safety net care. However, safety net patients may experience fluctuating prescription drug coverage, affecting the performance of adherence measures. Objective To evaluate the performance of continuous medication gap (CMG) for diverse, low-income managed care members with diabetes. Methods We conducted this cross-sectional analysis using administrative and clinical data for 680 members eligible for a self-management support trial at a non-profit, government-sponsored managed care plan. We applied CMG methodology to cardiometabolic medication claims for English-, Cantonese-, or Spanish-speaking members with diabetes. We examined inclusiveness (the proportion with calculable CMG) and selectivity (sociodemographic and medical differences from members without CMG). To examine validity, we examined unadjusted associations of suboptimal adherence (CMG>20%) with suboptimal cardiometabolic control. Results 429 members (63%) had calculable CMG. Compared to members without CMG, members with CMG were younger; more likely employed; and had poorer glycemic control, but better blood pressure and lipid control. Suboptimal adherence occurred more frequently among members with poor cardiometabolic control than among members with optimal control (28% vs. 12%, p=0.02). Conclusions CMG demonstrated acceptable inclusiveness and validity in a diverse, low-income safety net population, comparable to its performance in studies among other insured populations. CMG may provide a useful tool to measure adherence among increasingly diverse Medicaid populations, complemented by other strategies to reach those not captured by CMG.

Background Spirituality may influence how patients cope with their illness. Objectives We assessed whether spirituality may influence adherence to management of outpatients with heart failure. Methods Cross sectional study enrolling consecutive ambulatory heart failure patients in whom adherence to multidisciplinary treatment was evaluated. Patients were assessed for quality of life, depression, religiosity and spirituality utilizing validated questionnaires. Correlations between adherence and psychosocial variables of interest were obtained. Logistic regression models explored independent predictors of adherence. Results One hundred and thirty patients (age 60 ± 13 years; 67% male) were interviewed. Adequate adherence score was observed in 38.5% of the patients. Neither depression nor religiosity was correlated to adherence, when assessed separately. Interestingly, spirituality, when assessed by both total score sum (r = 0.26; p = 0.003) and by all specific domains, was positively correlated to adherence. Finally, the combination of spirituality, religiosity and personal beliefs was an independent predictor of adherence when adjusted for demographics, clinical characteristics and psychosocial instruments. Conclusion Spirituality, religiosity and personal beliefs were the only variables consistently associated with compliance to medication in a cohort of outpatients with heart failure. Our data suggest that adequately addressing these aspects on patient’s care may lead to an improvement in adherence patterns in the complex heart failure management. PMID:27192385

Background Simulation training may improve proficiency at and reduces complications from central venous catheter (CVC) placement, but the scope of simulation’s effect remains unclear. This randomized controlled trial evaluated the effects of a pragmatic CVC simulation program on procedural protocol adherence, technical skill, and patient outcomes. Methods Internal medicine interns were randomized to standard training for CVC insertion or standard training plus simulation-based mastery training. Standard training involved a lecture, a video-based online module, and instruction by the supervising physician during actual CVC insertions. Intervention-group subjects additionally underwent supervised training on a venous access simulator until they demonstrated procedural competence. Raters evaluated interns’ performance during internal jugular CVC placement on actual patients in the medical intensive care unit. Generalized estimating equations were used to account for outcome clustering within trainees. Results We observed 52 interns place 87 CVCs. Simulation-trained interns exhibited better adherence to prescribed procedural technique than interns who received only standard training (p=0.024). There were no significant differences detected in first-attempt or overall cannulation success rates, mean needle passes, global assessment scores or complication rates. Conclusions Simulation training added to standard training improved protocol adherence during CVC insertion by novice practitioners. This study may have been too small to detect meaningful differences in venous cannulation proficiency and other clinical outcomes, highlighting the difficulty of patient-centered simulation research in settings where poor outcomes are rare. For high-performing systems, where protocol deviations may provide an important proxy for rare procedural complications, simulation may improve CVC insertion quality and safety. PMID:26154250

Statins are efficacious in reducing the risk of major cardiovascular events for both primary and secondary prevention, yet long-term adherence is poor. Their effectiveness could be compromised in actual practice when patients are not adherent to the treatments. Higher copayments have been shown to be associated with lower adherence to statins. To assess the effect on patient adherence of moving branded atorvastatin and rosuvastatin from the second to the first tier by a Medicare Part D plan sponsor. Pharmacy claims and eligibility records between July 1, 2009, and July 31, 2011, of Medicare Part D members not receiving the low-income subsidy were analyzed. New atorvastatin and rosuvastatin users in January 2010 (2010 cohort) were compared with those in January 2011 (2011 cohort) after this formulary tier change (tier-reduction group). Adherence was defined by the proportion of days covered (PDC) over 6 months. The impact of tier reduction on adherence was evaluated via logistic regression for binary outcome (PDC≥0.8) and generalized linear regression for continuous PDC by comparing the 2011 cohort with the 2010 cohort, adjusting for demographic and clinical characteristics. Other statin users (97% on generic statins) were also analyzed, serving as a nontier-reduction comparator group. We identified 12,437 members in the tier-reduction group. Between the 2010 and 2011 cohorts, mean PDC increased from 0.77 to 0.83, and the proportion of members with high adherence increased from 62.0% to 72.9% (both P < 0.001). After regression adjustment, members in the 2011 cohort were more likely to be adherent (OR=1.68; 95% CI=1.55-1.82) and had a 5.9% increase in PDC (P < 0.05). There was no significant increase in adherence observed in the comparator nontier-reduction group. Findings from this study suggest that financial incentives may improve medication adherence. Future studies should evaluate whether such formulary strategies improve long-term adherence and patient

High adherence is necessary to realize health gains from water quality interventions.

Safe drinking water is critical for health. Household water treatment (HWT) has been recommended for improving access to potable water where existing sources are unsafe. Reports of low adherence to HWT may limit the usefulness of this approach, however. We constructed a quantitative microbial risk model to predict gains in health attributable to water quality interventions based on a range of assumptions about pre-treatment water quality; treatment effectiveness in reducing bacteria, viruses, and protozoan parasites; adherence to treatment interventions; volume of water consumed per person per day; and other variables. According to mean estimates, greater than 500 DALYs may be averted per 100,000 person-years with increased access to safe water, assuming moderately poor pre-treatment water quality that is a source of risk and high treatment adherence (>90% of water consumed is treated). A decline in adherence from 100% to 90% reduces predicted health gains by up to 96%, with sharpest declines when pre-treatment water quality is of higher risk. Results suggest that high adherence is essential in order to realize potential health gains from HWT.

Background: Patients prescribed with medication that treats mental health conditions benefit the most compared to those prescribed with other types of medication. However, they are also the most difficult to adhere. The development of mobile health (mHealth) applications ("apps") to help patients monitor their adherence is fast growing but with limited evidence on their efficacy. There is no evidence on the content of these apps for patients taking psychotropic medication. The aim of this study is to identify and evaluate the aims and functioning of available apps that are aiming to help and educate patients to adhere to medication that treats mental health conditions. Method: Three platform descriptions (Apple, Google, and Microsoft) were searched between October 2015 and February 2016. Included apps need to focus on adherence to medication that treats mental health conditions and use at least a reinforcement strategy. Descriptive information was extracted and apps evaluated on a number of assessment criteria using content analysis. Results: Sixteen apps were identified. All apps included self-monitoring properties like reminders and psycho-educational properties like mood logs. It was unclear how the latter were used or how adherence was measured. Major barriers to medication adherence like patients' illness and medication beliefs and attitudes were not considered nor where information to patients about mediation side effects. Very few apps were tailored and none was developed based on established theories explaining the processes for successful medication adherence like cognitions and beliefs. Reported information on app development and validation was poor. Discussion: A variety of apps with different properties that tackle both intentional and unintentional non-adherence from a different perspective are identified. An evidence-based approach and co-creation with patients is needed. This will ensure that the apps increase the possibility to impact on non-adherence

Poor adherence to immunosuppressive medications is a major cause of premature graft loss among children and young adults. Multicomponent interventions have shown promise but have not been fully evaluated. Unblinded parallel-arm randomized trial to assess the efficacy of a clinic-based adherence-promoting intervention. Prevalent kidney transplant recipients 11 to 24 years of age and 3 or more months posttransplantation at 8 kidney transplantation centers in Canada and the United States (February 2012 to May 2016) were included. Adherence was electronically monitored in all participants during a 3-month run-in, followed by a 12-month intervention. Participants assigned to the TAKE-IT intervention could choose to receive text message, e-mail, and/or visual cue dose reminders and met with a coach at 3-month intervals when adherence data from the prior 3 months were reviewed with the participant. "Action-Focused Problem Solving" was used to address adherence barriers selected as important by the participant. Participants assigned to the control group met with coaches at 3-month intervals but received no feedback about adherence data. The primary outcomes were electronically measured "taking" adherence (the proportion of prescribed doses of immunosuppressive medications taken) and "timing" adherence (the proportion of doses of immunosuppressive medications taken between 1 hour before and 2 hours after the prescribed time of administration) on each day of observation. Secondary outcomes included the standard deviation of tacrolimus trough concentrations, self-reported adherence, acute rejection, and graft failure. 81 patients were assigned to intervention (median age, 15.5 years; 57% male) and 88 to the control group (median age, 15.8 years; 61% male). Electronic adherence data were available for 64 intervention and 74 control participants. Participants in the intervention group had significantly greater odds of taking prescribed medications (OR, 1.66; 95% CI, 1

Background Food insecurity is increasingly reported as an important barrier of patient adherence to antiretroviral therapy (ART) in both resource-poor and rich settings. However, unlike in resource rich-settings, very few quantitative studies to date have investigated the association of food insecurity with patient adherence to ART in Sub-Saharan Africa. The current study examines the association between food insecurity and adherence to ART among HIV-infected adults in the Democratic Republic of Congo (DRC). Methods and Findings This is a cross-sectional quantitative study of patients receiving ART at three private and one public health facilities in Kinshasa, DRC. Participants were consecutively recruited into the study between April and November 2012. Adherence was measured using a combined method coupling pharmacy refill and self-reported adherence. Food insecurity was the primary predictor, and was assessed using the Household Food Insecurity Access Scale (HFIAS). Of the 898 participants recruited into the study, 512 (57%) were food insecure, and 188 (20.9%) were not adherent to ART. Food insecurity was significantly associated with non-adherence to ART (AOR, 2.06; CI, 1.38–3.09). We also found that perceived harmfulness of ART and psychological distress were associated respectively with increased (AOR, 1.95; CI, 1.15–3.32) and decreased (AOR, 0.31; CI, 0.11–0.83) odds of non-adherence to ART. Conclusion Food insecurity is prevalent and a significant risk factor for non-adherence to ART among HIV-infected individuals in the DRC. Our findings highlight the urgent need for strategies to improve food access among HIV-infected on ART in order to ensure patient adherence to ART and ultimately the long-term success of HIV treatment in Sub-Saharan Africa.

Background Product adherence is a pivotal issue in the development of effective vaginal microbicides to reduce sexual transmission of HIV. To date, the six Phase III studies of vaginal gel products have relied primarily on self-reporting of adherence. Accurate and reliable methods for monitoring user adherence to microbicide-releasing vaginal rings have yet to be established. Methods A silicone elastomer vaginal ring prototype containing an embedded, miniature temperature logger has been developed and tested in vitro and in cynomolgus macaques for its potential to continuously monitor environmental temperature and accurately determine episodes of ring insertion and removal. Results In vitro studies demonstrated that DST nano-T temperature loggers encapsulated in medical grade silicone elastomer were able to accurately and continuously measure environmental temperature. The devices responded quickly to temperature changes despite being embedded in different thickness of silicone elastomer. Prototype vaginal rings measured higher temperatures compared with a subcutaneously implanted device, showed high sensitivity to diurnal fluctuations in vaginal temperature, and accurately detected periods of ring removal when tested in macaques. Conclusions Vaginal rings containing embedded temperature loggers may be useful in the assessment of product adherence in late-stage clinical trials. PMID:25965956

This study examined patterns, potential predictors, and outcomes of immunosuppressive medication adherence in a convenience sample of 121 kidney transplant recipients aged 21 yr or older from three kidney transplant centers using a theory-based, descriptive, correlational, longitudinal design. Electronic monitoring was conducted for 12 months using electronic monitoring. Participants were persistent in taking their immunosuppressive medications, but execution, which includes both taking and timing, was poor. Older age was the only demographic variable associated with medication adherence (r = 0.25; p = 0.005). Of the potential predictors examined, only medication self-efficacy was associated with medication non-adherence, explaining about 9% of the variance (r = 0.31, p = 0.0006). The few poor outcomes that occurred were not significantly associated with medication non-adherence, although the small number of poor outcomes may have limited our ability to detect a link. Future research should test fully powered, theory-based, experimental interventions that include a medication self-efficacy component. © 2013 John Wiley & Sons A/S.

Patient medical costs for tuberculosis treatment and impact on adherence in China: a systematic review

2011-01-01

Background Charging for tuberculosis (TB) treatment could reduce completion rates, particularly in the poor. We identified and synthesised studies that measure costs of TB treatment, estimates of adherence and the potential impact of charging on treatment completion in China. Methods Inclusion criteria were primary research studies, including surveys and studies using qualitative methods, conducted in mainland China. We searched MEDLINE, PUBMED, EMBASE, Science Direct, HEED, CNKI to June 2010; and web pages of relevant Chinese and international organisations. Cost estimates were extracted, transformed, and expressed in absolute values and as a percentage of household income. Results Low income patients, defined at household or district level, pay a total of US$ 149 to 724 (RMB 1241 to 5228) for medical costs for a treatment course; as a percentage of annual household income, estimates range from 42% to 119%. One national survey showed 73% of TB patients at the time of the survey had interrupted or suspended treatment, and estimates from 9 smaller more recent studies showed that the proportion of patients at the time of the survey who had run out of drugs or were not taking them ranged from 3 to 25%. Synthesis of surveys and qualitative research indicate that cost is the most cited reason for default. Conclusions Despite a policy of free drug treatment for TB in China, health services charge all income groups, and costs are high. Adherence measured in cross sectional surveys is often low, and the cumulative failure to adhere is likely to be much higher. These findings may be relevant to those concerned with the development and spread of multi-drug resistant TB. New strategies need to take this into account and ensure patient adherence.

Non-adherence to safer sex and non-adherence to ART can each have adverse health consequences for HIV-infected individuals and their sex partners, but little is known about the association of these behaviors with each other. This "dual risk" has potential negative public health consequences since non-adherence can lead to the development of resistant virus that can then be transmitted to sex partners. Among participants in the Multi-site Adherence Collaboration in HIV we examined, at study baseline, the association between the frequency of unprotected sex (assessed by self-report) and ART adherence (assessed by Medication Event Monitoring System, Aardex) among the sexually active participants in the five studies (N = 459) that collected sexual risk behavior. The bivariate association between sexual risk behaviors and ART adherence was assessed by Pearson correlations; subsequently regression analyses were used to evaluate the role of demographic characteristics, depression and substance use in explaining the "dual risk" outcome (sexual risk and non-adherence). Among participants who had been sexually active, more unprotected anal/vaginal sex was weakly associated with poorer ART adherence (r = -0.12, p = 0.01 for the overall sample). Further analysis showed this association was driven by the heterosexual men in the sample (r = -0.29, p < 0.001), and was significant only for this group, and not for gay/bisexual men or for women (heterosexual and homosexual). Neither substance use nor depression accounted for the association between sexual risk and ART adherence. HIV-infected heterosexual men who are having difficulty adhering to ART are also more likely to engage in risky sexual behaviors and therefore may benefit from counseling about these risk behaviors. We must identify procedures to screen for these risk behaviors and develop interventions, appropriately tailored to specific populations and identified risk factors, that can be integrated into routine clinical

2014-01-01

Objective To understand independent pathways linking emotional distress, medication adherence and glycemic control in adults with type 2 diabetes, as well as the potential mediating effects of perceived control over illness and self-efficacy. Methods Adults with type 2 diabetes (N = 142) were recruited for an intervention study evaluating cognitive behavioral therapy for adherence and depression. Depressive symptom severity was assessed via semi-structured interview. Validated self-reports assessed diabetes-related distress, perceived control over diabetes (perceived control), self-efficacy for diabetes self-management and medication adherence. Glycemic control was evaluated by hemoglobin A1c (A1C). Only baseline data were included in correlational and linear regression analyses. Results Perceived control was an important mediator for both medication adherence and A1C outcomes. Specifically, regression analyses demonstrated that diabetes distress, but not depression severity, was significantly related to medication adherence and A1C. Self-efficacy and perceived control were also independently associated with medication adherence and A1C. Mediation analyses demonstrated a significant indirect effect for diabetes distress and medication adherence, through perceived control and self-efficacy. The relationship between distress and A1C was accounted for by an indirect effect through perceived control. Conclusion Results demonstrate that diabetes-related emotional distress is associated with poorer treatment adherence and glycemic control among adults with type 2 diabetes; these relationships were partially mediated through perceived control over diabetes. Perceptions of one’s personal ability to influence diabetes may be important in understanding the pathway between emotional distress and poor diabetes treatment outcomes. PMID:25110840

Aims To describe pharmacy education, research, practice and policy related to medication adherence in Finland since the year 2000. Methods The three universities that provide pharmacy education (Åbo Akademi, University of Eastern Finland, and University of Helsinki) completed a structured pro-forma questionnaire regarding education related to medication adherence. A MEDLINE and EMBASE literature search was performed to identify English language peer-reviewed research that reported medication compliance, adherence or persistence. The Ministry of Social Affairs and Health was invited to nominate policies and documents related to medication adherence. A narrative review of medication counselling practices and professional service delivery through Finnish community pharmacies was undertaken. Results Medication adherence was a theme integrated into obligatory and elective courses for bachelors and masters degree students. The literature search identified 33 English language peer-reviewed research articles reporting medication compliance, adherence or persistence published since the year 2000. Policy documents of the Ministry of Social Affairs and Health recognise that poor medication adherence may lead to suboptimal treatment outcomes, and encourage patient participation in treatment decision making. Adherence practice in Finnish pharmacies has been strongly linked to the development of medication counselling services. Conclusions Adherence research and education has focused on understanding and addressing the contextual factors that contribute to medication nonadherence. Adherence practice in community pharmacies has tended to focus on medication counselling and programs specific to particular disease states. Medication adherence is a topic that is integrated into courses for bachelor’s and master’s level pharmacy students in Finland. PMID:25126134

To determine the extent to which targets for blood pressure (BP) (<140.90 mmHg) and random blood glucose level (BGL) (<7.7 mmol/L) control in patients with chronic kidney disease (CKD) are achieved; and the extent clinical inertia affects BP and glucose control in CKD and diabetes mellitus (DM). Data was collected from the 1st January 2015 until 31st December 2015 on key patient pathology, admission reason, final discharge diagnosis, and information concerning clinical guideline adherence. Eighty-seven (n = 87) CKD patients were included. The average hospital BP for all CKD patients was 134.3/73.4 mmHg, adhering to recommendations of <140/90 mmHg. The average CKD patient pre-admission BP was 134.8/72.2 mmHg compared to the discharge BP of 129.8/72.2 mmHg. At admission, 63.3% and 93.1% of patients adhered to systolic and diastolic BP recommendations, which significantly (p = < .05) increased at discharge to a systolic and diastolic BP adherence of 83.9% and 98.8%, respectively. The average random hospital BGL was 7.7 mmol/L, indicating good control, whereas the pre-hospital HbA1c average was 7.58%, indicating poor control (>7.0% >53 mmol/mol). There were 21 cases of clinical inertia, affecting 18 out of 87 patients (20.7%), with significant adverse hospital discharge differences (p = <.05) between clinical inertia and non- clinical inertia patient systolic BP (144.2 vs. 132.8 mmHg), deranged BGL (66.7% vs. 35.3%), and reduction in kidney function (83.3% vs. 30.9%). Adherence appears to be related to inpatient clinical inertia and outpatient patient health literacy and empowerment. Copyright © 2017 Diabetes India. Published by Elsevier Ltd. All rights reserved.

To assess the features and level of health literacy (HL) of available medication adherence apps and to create a searchable website to assist health care providers (HCP) and patients identify quality adherence apps. Medication nonadherence continues to be a significant problem and leads to poor health outcomes and avoidable health care expense. The average adherence rate for chronic medications, regardless of disease state, is approximately 50% leaving significant room for improvement. Smartphone adherence apps are a novel resource to address medication nonadherence. With widespread smartphone use and the growing number of adherence apps, both HCP and patients should be able to identify quality adherence apps to maximize potential benefits. Assess the features, functionality and level of HL of available adherence apps and create a searchable website to help both HCP and patients identify quality adherence apps. Online marketplaces (iTunes, Google Play, Blackberry) were searched in June of 2014 to identify available adherence apps. Online descriptions were recorded and scored based on 28 author-identified features across 4 domains. The 100 highest-scoring apps were user-tested with a standardized regimen to evaluate their functionality and level of HL. 461 adherence apps were identified. 367 unique apps were evaluated after removing "Lite/Trial" versions. The median initial score based on descriptions was 15 (max of 68; range: 3 to 47). Only 77 apps of the top 100 highest-scoring apps completed user-testing and HL evaluations. The median overall user-testing score was 30 (max of 73; range: 16 to 55). App design, functionality, and level of HL varies widely among adherence apps. While no app is perfect, several apps scored highly across all domains. The website www.medappfinder.com is a searchable tool that helps HCP and patients identify quality apps in a crowded marketplace. Copyright © 2016 American Pharmacists Association®.

Antihypertensive drug adherence (ADA) is a mainstay in blood pressure control. Education through mobile phone short message system (SMS) text messaging could improve ADA. The authors conducted a randomized study involving 314 patients with hypertension with <6 months of antihypertensive treatment from the Preventive Health Program of 12 different primary care centers in Santiago, Chile. Patients were randomly assigned to receive or not receive SMS related to ADA and healthy lifestyle. Adherence was assessed by the self-reported four-item scale Morisky-Green-Levine questionnaire at baseline and after 6 months of follow-up, with four of four positive questions classified as good adherence. Group comparison for adherence was performed by means of a logistic regression model, adjusting by baseline adherence, age older than 60 years, and sex. A total of 163 patients were randomized to receive and 151 to not receive SMS. After 6 months of follow-up, ADA in the non-SMS group decreased from 59.3% to 51.4% (P=.1). By contrast, adherence increased from 49% to 62.3% (P=.01) in the SMS group. Text messaging intervention improved ADA (risk ratio, 1.3; 95% confidence interval, 1.0-1.6 [P<.05]). At 6-month follow-up, text messaging resulted in an increase in reporting ADA in this hypertensive Latino population. This approach could become an effective tool to overcome poor medication adherence in the community. ©2017 Wiley Periodicals, Inc.

Background While medication adherence is essential for the secondary prevention of stroke, it is often sub-optimal, and can be compromised by cognitive impairment. This study aimed to systematically review and meta-analyse the association between cognitive impairment and medication non-adherence in stroke. Methods A systematic literature search of longitudinal and cross-sectional studies of adults with any stroke type, which reported on the association between any measure of non-adherence and cognitive impairment, was carried out according to PRISMA guidelines. Odds ratios and 95% confidence intervals were the primary measure of effect. Risk of bias was assessed using the Cochrane Bias Methods Group's Tool to Assess Risk of Bias in Cohort Studies, with evidence quality assessed according to the GRADE approach. We conducted sensitivity analyses according to measure of cognitive impairment, measure of medication adherence, population, risk of bias and adjustment for covariates. The protocol was registered with PROSPERO. Results From 1,760 titles and abstracts, we identified 9 studies for inclusion. Measures of cognitive impairment varied from dementia diagnosis to standardised cognitive assessments. Medication adherence was assessed through self-report or administrative databases. The majority of studies were of medium risk of bias (n = 6); two studies had low risk of bias. Findings were mixed; when all studies were pooled, there was no evidence of an association between cognitive impairment and medication non-adherence post-stroke [OR (95% CI): 0.85 (0.66, 1.03)]. However, heterogeneity was substantial [I2 = 90.9%, p < .001], and the overall evidence quality was low. Conclusions Few studies have explored associations between cognitive impairment and medication adherence post-stroke, with substantial heterogeneity in study populations, and definitions and assessments of non-adherence and cognitive impairment.

Every year, approximately 260,000 children are infected with HIV in low- and middle-income countries. The timely initiation and high level of maintenance of antiretroviral therapy (ART) are crucial to reducing the suffering of HIV-positive children. We need to develop a better understanding of the background of children's ART non-adherence because it is not well understood. The purpose of this study is to explore the background related to ART non-adherence, specifically in relation to the orphan status of children in Kigali, Rwanda. We conducted 19 focus group discussions with a total of 121 caregivers of HIV-positive children in Kigali. The primary data for analysis were verbatim transcripts and socio-demographic data. A content analysis was performed for qualitative data analysis and interpretation. The study found several contextual factors that influenced non-adherence: among double orphans, there was psychological distance between the caregivers and children, whereas economic burden was the primary issue among paternal orphans. The factors promoting adherence also were unique to each orphan status, such as the positive attitude about disclosing serostatus to the child by double orphans' caregivers, and feelings of guilt about the child's condition among non-orphaned caregivers. Knowledge of orphan status is essential to elucidate the factors influencing ART adherence among HIV-positive children. In this qualitative study, we identified the orphan-related contextual factors that influenced ART adherence. Understanding the social context is important in dealing with the challenges to ART adherence among HIV-positive children.

2013-01-01

Background The few studies on post-Essure hysterosalpingogram (HSG) adherence rates show inconsistent results. This study examined associations between sociodemographic variables not examined in prior studies and HSG adherence among low income women. Study Design Medical records of 286 women who underwent sterilization between August 31, 2005 and September 30, 2011 were reviewed. Chi-square and Mann-Whitney tests were used to determine variable associations with HSG adherence. Results The adherence rate for the first HSG was 85.0% (243/286). Variables associated with adherence were: lower education level (p=.01), not working outside the home (p=.04), being married (p<.0001), lower gravidity (p=.03), fewer lifetime number of sexual partners (p<.0001), no sexually transmitted infection history (p<.01), Hispanic ethnicity (p<.0001), Spanish as a primary language (p<.0001) and living further from the clinic (p<.01). Conclusions This study demonstrates that achieving high rates of adherence with the recommended HSG following Essure placement is feasible among low income populations. Furthermore, not speaking English or having to commute a far distance to the clinic do not appear to be barriers. This is encouraging considering the importance of this test to confirm tubal occlusion. PMID:24012097

Adherence to pharmacotherapy reduces symptoms of asthma and rhinitis, however, little is known of its impact on school performance. To evaluate the impact of pharmacotherapy in absenteeism and school performance in a child population. A cross-sectional study, carried out in eight schools. All participants and their parents were given a questionnaire assessing parameters related to respiratory diseases and pharmacotherapy. Data on school performance was obtained from the academic history of each child who participated in the study. Adherence to pharmacotherapy was classified as a correct use of therapy for more than five days per week. 1109 children agreed to participate. Students were divided into two groups: symptomatic (36%) and asymptomatic (63%). The symptomatic group had a higher frequency of school absenteeism (1 vs. 3.1days/year/patient p<0.01) and lower academic performance (failed: 20% vs. 33% p<0.01). After dividing the symptomatic group between adherents and non-adherents to the pharmacotherapy, the group of adherents had a similar school performance to the asymptomatic group and it was significantly different from the no-adherent group. Respiratory symptoms are associated with poor school performance and with an increase in school absenteeism, but adherence to pharmacotherapy can reduce these negative impacts in children.

2014-11-30

We investigated levels of insight among patients with Social Anxiety Disorder (SAD) as compared to patients with Obsessive-Compulsive Disorder (OCD) and evaluated whether levels of insight in SAD were related to specific sociodemographic and/or clinical features. Thirty-seven SAD patients and 51 OCD patients attending a tertiary obsessive-compulsive and anxiety disorders clinic were assessed with a sociodemographic and clinical questionnaire, a structured diagnostic interview, the Brown Assessment of Beliefs Scale (BABS), the Social Phobia Inventory (SPIN), the Beck Depression Inventory (BDI), the Sheehan Disability Scale (SDS), and the Treatment Adherence Survey-patient version (TAS-P). According to the BABS, SAD patients exhibited insight levels that were as low as those exhibited by OCD patients, with up to 29.7% of them being described as "poor insight" SAD. Although poor insight SAD patients were more frequently married, less depressed and displayed a statistical trend towards greater rates of early drop-out from cognitive-behavioral therapy, their insight levels were not associated with other variables of interest, including sex, age, employment, age at onset, duration of illness, associated psychiatric disorders, SPIN and SDS scores. Patients with poor insight SAD might perceive their symptoms as being less distressful and thus report fewer depressive symptoms and high rates of treatment non-adherence.

2012-01-01

Background Patient adherence is an important component of the treatment of chronic disease. An understanding of patient adherence and its modulating factors is necessary to correctly interpret treatment efficacy and barriers to therapeutic success. Purpose This meta-analysis aims to systematically review published randomized controlled trials of reminder interventions to assist patient adherence to prescribed medications. Methods A Medline search was performed for randomized controlled trials published between 1968 and June 2011, which studied the effect of reminder-based interventions on adherence to self-administered daily medications. Results Eleven published randomized controlled trials were found between 1999 and 2009 which measured adherence to a daily medication in a group receiving reminder interventions compared to controls receiving no reminders. Medication adherence was measured as the number of doses taken compared to the number prescribed within a set period of time. Meta- analysis showed a statistically significant increase in adherence in groups receiving a reminder intervention compared to controls (66.61% versus 54.71%, 95% CI for mean: 0.8% to 22.4%). Self-reported and electronically monitored adherence rates did not significantly differ (68.04% versus 63.67%, P = 1.0). Eight of eleven studies showed a statistically significant increase in adherence for at least one of the reminder group arms compared to the control groups receiving no reminder intervention. Limitations The data are limited by imperfect measures of adherence due to variability in data collection methods. It is also likely that concomitant educational efforts in the study populations, such as instructions regarding proper administration and importance of correct dosing schedules, contributed to improved patient adherence, both in reminder and control arms. The search strategy could have missed relevant studies which were categorized by disease rather than adherence. Conclusions

Poor patient adherence is often the reason for suboptimal blood pressure control. Electronic monitoring is one method of assessing adherence. The aim was to systematically review the literature on electronic monitoring of patient adherence to self-administered oral antihypertensive medications. We searched the Pubmed, Embase, Cinahl and Psychinfo databases and websites of suppliers of electronic monitoring devices. The quality of the studies was assessed according to the quality criteria proposed by Haynes et al. Sixty-two articles were included; three met the criteria proposed by Haynes et al. and nine reported the use of electronic adherence monitoring for feedback interventions. Adherence rates were generally high, whereas average study quality was low with a recent tendency towards improved quality. One study detected investigator fraud based on electronic monitoring data. Use of electronic monitoring of patient adherence according to the quality criteria proposed by Haynes et al. has been rather limited during the past two decades. Electronic monitoring has mainly been used as a measurement tool, but it seems to have the potential to significantly improve blood pressure control as well and should be used more widely.

Abstract Antipsychotics are the drugs prescribed to treat psychotic disorders; however, patients often fail to adhere to their treatment, and this has a severe negative effect on prognosis in these kinds of illnesses. Among the wide range of risk factors for treatment nonadherence, this systematic review covers those that are most important from the point of view of clinicians and patients and proposes guidelines for addressing them. Analyzing 38 studies conducted in a total of 51,796 patients, including patients with schizophrenia spectrum disorders and bipolar disorder, we found that younger age, substance abuse, poor insight, cognitive impairments, low level of education, minority ethnicity, poor therapeutic alliance, experience of barriers to care, high intensity of delusional symptoms and suspiciousness, and low socioeconomic status are the main risk factors for medication nonadherence in both types of disorder. In the future, prospective studies should be conducted on the use of personalized patient-tailored treatments, taking into account risk factors that may affect each individual, to assess the ability of such approaches to improve adherence and hence prognosis in these patients.

To describe patterns of treatment adherence to early maintenance phase therapy for acute lymphoblastic leukemia (ALL) and lymphoblastic lymphoma (LBL). Using an objective observational method (electronic monitoring), adherence was examined for 139 patients aged 7-19 years diagnosed with ALL or LBL across 6 centers. The mean adherence percentage was 86.2%. Adherence rates declined over the 1-month of follow-up to 83%. 3 linear trajectories of 6-mercaptopurine adherence were identified: (1) exemplary adherence (n = 99): Averaging nearly 100%; (2) deteriorating (n = 23): Adherence decreased from 100 to 60%; and (3) chronically poor adherence (n = 9): Averaging 40%. Adherence promotion interventions might be tailored to subgroups of patients who demonstrated problematic patterns of treatment adherence that could place them at risk for relapse. This research demonstrates the importance of using objective real-time measures of medication adherence for measuring and documenting adherence patterns. © The Author 2013.

Integrative Review of Mobile Phone Contacts and Medication Adherence in Severe Mental Illness.

PubMed

Bright, Cordellia E

Poor medication adherence is a significant problem in individuals with severe mental illness (SMI). About 50% of people with SMI become nonadherent to treatment in the first month following discharge from the hospital. This study examined literature in the past decade (2006-2016) on the use of mobile phone contacts in individuals with SMI to improve medication adherence post hospital discharge. This integrative review used the search terms texting, text messaging, SMS, cell/mobile phone, medication adherence, medication compliance, and mental illness. Databases (CINAHL, PubMed, PsycINFO, and Scopus) and manual searching of reference lists were done. The main inclusion criteria were the use of mobile phone contacts on medication adherence in individuals with SMI. Adults 18 years and older, studies conducted from 2006 to 2016, and studies conducted in English were also criteria for inclusion. Only five studies met criteria for inclusion. Outcomes from the review showed that mobile phone contacts have been used to improve medication adherence in individuals with SMI and able to provide the four types of social support (instrumental, informational, emotional, and, appraisal). When phone contacts especially text messaging was used as an adjunct to other interventions, it yielded better medication adherence than when used alone. However, results on medication adherence rates were mixed in participants on both psychiatric and nonpsychiatric medications. Although mobile phone contacts are a promising tool to enhance medication adherence after hospital discharge, its effectiveness to increase medication adherence in this population remains inconclusive.

Background It has been increasingly recognized that non-adherence is an important factor that determines the outcome of peritoneal dialysis (PD) therapy. There is therefore a need to establish the levels of non-adherence to different aspects of the PD regimen (dialysis procedures, medications, and dietary/fluid restrictions). Methods A systematic review of peer-reviewed literature was performed in PubMed, PsycINFO and CINAHL databases using PRISMA guidelines in May 2013. Publications on non-adherence in PD were selected by two reviewers independently according to predefined inclusion and exclusion criteria. Relevant data on patient characteristics, measures, rates and factors associated with non-adherence were extracted. The quality of studies was also evaluated independently by two reviewers according to a revised version of the Effective Public Health Practice Project assessment tool. Results The search retrieved 204 studies, of which a total of 25 studies met inclusion criteria. Reported rates of non-adherence varied across studies: 2.6–53% for dialysis exchanges, 3.9–85% for medication, and 14.4–67% for diet/fluid restrictions. Methodological differences in measurement and definition of non-adherence underlie the observed variation. Factors associated with non-adherence that showed a degree of consistency were mostly socio-demographical, such as age, employment status, ethnicity, sex, and time period on PD treatment. Conclusion Non-adherence to different dimensions of the dialysis regimen appears to be prevalent in PD patients. There is a need for further, high-quality research to explore these factors in more detail, with the aim of informing intervention designs to facilitate adherence in this patient population.

Adherence to antiretroviral therapy (ART) during the early months of treatment in rural Zambia: influence of demographic characteristics and social surroundings of patients

PubMed Central

2012-01-01

Background Around 70% of those living with HIV in need of treatment accessed antiretroviral therapy (ART) in Zambia by 2009. However, sustaining high levels of adherence to ART is a challenge. This study aimed to identify the predictive factors associated with ART adherence during the early months of treatment in rural Zambia. Methods This is a field based observational longitudinal study in Mumbwa district, which is located 150 km west of Lusaka, the capital of Zambia. Treatment naive patients aged over 15 years, who initiated treatment during September-November 2010, were enrolled. Patients were interviewed at the initiation and six weeks later. The treatment adherence was measured according to self-reporting by the patients. Multiple logistic regression analysis was performed to identify the predictive factors associated with the adherence. Results Of 157 patients, 59.9% were fully adherent to the treatment six weeks after starting ART. According to the multivariable analysis, full adherence was associated with being female [Adjusted Odds Ratio (AOR), 3.3; 95% Confidence interval (CI), 1.2-8.9], having a spouse who were also on ART (AOR, 4.4; 95% CI, 1.5-13.1), and experience of food insufficiency in the previous 30 days (AOR, 5.0; 95% CI, 1.8-13.8). Some of the most common reasons for missed doses were long distance to health facilities (n = 21, 53.8%), food insufficiency (n = 20, 51.3%), and being busy with other activities such as work (n = 15, 38.5%). Conclusions The treatment adherence continues to be a significant challenge in rural Zambia. Social supports from spouses and people on ART could facilitate their treatment adherence. This is likely to require attention by ART services in the future, focusing on different social influences on male and female in rural Zambia. In addition, poverty reduction strategies may help to reinforce adherence to ART and could mitigate the influence of HIV infection for poor patients and those who fall into poverty after

Ambulatory blood pressure and adherence monitoring: diagnosing pseudoresistant hypertension.

PubMed

Burnier, Michel; Wuerzner, Gregoire

2014-01-01

A small proportion of the treated hypertensive population consistently has a blood pressure greater than 140/90 mm Hg despite a triple therapy including a diuretic, a calcium channel blocker, and a blocker of the renin-angiotensin system. According to guidelines, these patients have so-called resistant hypertension. The prevalence of this clinical condition is higher in tertiary than primary care centers and often is associated with chronic kidney disease, diabetes, obesity, and sleep apnea syndrome. Exclusion of pseudoresistant hypertension using ambulatory or home blood pressure monitoring is a crucial step in the investigation of patients with resistant hypertension. Thus, among the multiple factors to consider when investigating patients with resistant hypertension, ambulatory blood pressure monitoring should be performed very early. Among other factors to consider, physicians should investigate patient adherence to therapy, assess the adequacy of treatment, exclude interfering factors, and, finally, look for secondary forms of hypertension. Poor adherence to therapy accounts for 30% to 50% of cases of resistance to therapy depending on the methodology used to diagnose adherence problems. This review discusses the clinical factors implicated in the pathogenesis of resistant hypertension with a particular emphasis on pseudoresistance, drug adherence, and the use of ambulatory blood pressure monitoring for the diagnosis and management of resistant hypertension.

2016-01-01

Objective: Poor treatment adherence is a major problem among individuals with chronic illness. Research indicates that adherence is worsened when accompanied by depressive symptoms. In this preliminary study, we aimed to describe how a patient-centered approach could be employed to aid patients with depressive symptoms in following their treatment regimens. Methods: The sample consisted of 14 patients undergoing antiretroviral therapy (ART) for HIV who reported clinically-significant depressive symptoms. Participant ratings of 23 treatment-related statements were examined using two assessment and analytic techniques. Interviews were conducted with participants to determine their views of information based on the technique. Results: Results indicate that while participants with optimal adherence focused on views of treatment associated with side effects to a greater extent than participants with poor adherence, they tended to relate these side effects to sources of intrinsic motivation. Conclusion: The study provides examples of how practitioners could employ the assessment techniques outlined to better understand how patients think about treatment and aid them in effectively framing their health-related goals.

Patients with persistent poorly controlled diabetes mellitus (PPDM), defined as an uninterrupted hemoglobin A1c >8.0% for ≥1 year despite standard care, are at high risk for complications. Additional research to define patient factors associated with PPDM could suggest barriers to improvement in this group and inform the development of targeted strategies to address these patients' resistant diabetes. We analyzed patients with type 2 diabetes from a multi-site randomized trial. We characterized patients with PPDM relative to other patients using detailed survey data and multivariable modeling. Of 963 patients, 118 (12%) had PPDM, 265 (28%) were intermittently poorly controlled, and 580 (60%) were well-controlled. Patients with PPDM had younger age, earlier diabetes diagnosis, insulin use, higher antihypertensive burden, higher low-density lipoprotein cholesterol, and lower statin use relative to well-controlled patients. Among patients with objective adherence data (Veterans Affairs patients), a larger oral diabetes medication refill gap was associated with PPDM. Strategies are needed to target-specific barriers to improvement among patients whose diabetes is resistant to standard diabetes care. Our data suggest that strategies for targeting PPDM should accommodate younger patients' lifestyles, include medication management for insulin titration and comorbid disease conditions, and address barriers to self-management adherence. © The Author(s) 2014 Reprints and permissions: sagepub.co.uk/journalsPermissions.nav.

A dramatic increase in the use of antiretroviral drugs in Africa has increased focus on adherence to treatment, which has so far been equivalent if not superior to that in northern contexts. The reasons for this exceptional adherence are poorly understood. In this paper, we examine adherence in the historical and ethnographic context of access to treatment in Burkina Faso, Côte d'Ivoire and Mali. Living where there is no social security and minimal, if any, medical care, individuals diagnosed with HIV are faced with the threat of illness, death, ostracism and destitution, and were obliged to negotiate conflicting networks of obligation, reciprocity, and value. HIV and AIDS programmes value efforts to address social, and indeed biological, vulnerability. In contrast, kinship-based social relationships may value individuals in other ways. These conflicting moral economies often intersect in the worlds of people living with HIV. HIV status can be used to claim resources from the public or non-governmental organization programmes. This may interfere with social networks that are the most stable source of material and emotional support. Self-help and empowerment techniques provided effective tools for people living with HIV to fashion themselves into effective advocates. In the early years of the use of antiretroviral therapy (ART), access to treatment was thus mediated by confessional practices and forms of social triage. We introduce the term 'therapeutic citizenship' to describe the way in which people living with HIV appropriate ART as a set of rights and responsibilities to negotiate these at times conflicting moral economies. Exemplary adherence should be viewed through the lens of therapeutic citizenship.

Celiac disease (CD) affects health-related quality of life (HRQOL) of patients suffering it. The exclusion of gluten from the diet (GFD) improves HRQOL, but involves difficulties in following the diet that could adversely affect HRQOL. To determine the effect of adherence to the diet on HRQOL of adult CD patients. A prospective, cross-sectional, multicenter study of CD patients treated with a GFD for longer than 1 year. Adherence to the GFD was measured using the Morisky scale, and health status using the specific CD-QOL questionnaire and the generic EuroQol-5D questionnaire. 366 patients from 7 hospitals were included: 71.5% of patients reported a perfect treatment adherence, 23.5% unintentional poor adherence and 5% intentional poor adherence. Good adherence to a GFD was related to a higher mean score onthe CD-QOL (75 vs. 68, respectively, p < 0.05) and EuroQol-5D (0.9 vs. 0.8, respectively, p < 0.05). Ease of adherence to a GFD was also related to a better HRQOL (total CD-QOL score of 82 vs. 67 in patients who consider the GFD difficult to follow, p < 0.05). Good symptom control was also related to a better HRQOL (total CD-QOL score of 78 vs. 67 in asymptomatic vs. symptomatic patients, p < 0.01). The worse scored dimension of CD-QOL was related to "inadequate treatment". In CD, good adherence to a GFD and adequate symptom control result in improved HRQOL. Many patients consider that the lack of therapeutic alternatives to diet worsens their quality of life.

Type 2 diabetes (T2DM) is a growing burden among all countries including Pakistan, with medication adherence very important to improve care. However, little is known about medication adherence in Pakistan and potential predictors among T2DM patients to provide future guidance. This needs to be addressed. Consequently, the present study sought to assess medication adherence among type 2 diabetic patients in Quetta city, Pakistan. Questionnaire based, descriptive study among 300 Pakistani patients attending public and private hospitals aged 18 years and above, having a confirmed diagnosis of T2DM, without additional co-morbidities were targeted. Descriptive statistics were used to describe demographic and disease characteristics. The association between socio-demographic data and study variables was compared through the Mann Whitney/Kruskal Wallis test (where applicable). The factors that were significantly associated with medication adherence were further assessed by logistic regression analysis. 55.6% of patients had high adherence although overall patients reported moderate adherence. Age, gender, education, diabetes-related knowledge and treatment satisfaction were significantly associated with medication adherence. Older males with only primary education and with poor diabetes-related knowledge had the lowest adherence. This study presents a model that is associated with medication adherence among T2DM patients, with disease-related knowledge as a significant predictor of likely adherence. Results of the current study revealed that improved diabetes related knowledge plays a significant role in improving medication adherence. Healthcare practitioners and the system should formalize and acknowledge patient education as a key component to treat patients with T2DM. This should include a greater role for pharmacists and other professionals.

Background It has been recognized that poor adherence can be a serious risk to the health and wellbeing of patients, and greater adherence to dietary advice is a critical component in preventing and managing chronic diseases. Objectives To assess the effects of interventions for enhancing adherence to dietary advice for preventing and managing chronic diseases in adults. Search methods We searched the following electronic databases up to 29 September 2010: The Cochrane Library (issue 9 2010), PubMed, EMBASE (Embase.com), CINAHL (Ebsco) and PsycINFO (PsycNET) with no language restrictions. We also reviewed: a) recent years of relevant conferences, symposium and colloquium proceedings and abstracts; b) web-based registries of clinical trials; and c) the bibliographies of included studies. Selection criteria We included randomized controlled trials that evaluated interventions enhancing adherence to dietary advice for preventing and managing chronic diseases in adults. Studies were eligible if the primary outcome was the client’s adherence to dietary advice. We defined ‘client’ as an adult participating in a chronic disease prevention or chronic disease management study involving dietary advice. Data collection and analysis Two review authors independently assessed the eligibility of the studies. They also assessed the risk of bias and extracted data using a modified version of the Cochrane Consumers and Communication Review Group data extraction template. Any discrepancies in judgement were resolved by discussion and consensus, or with a third review author. Because the studies differed widely with respect to interventions, measures of diet adherence, dietary advice, nature of the chronic diseases and duration of interventions and follow-up, we conducted a qualitative analysis. We classified included studies according to the function of the intervention and present results in a narrative table using vote counting for each category of intervention. Main results

Early aortic stenting in chronic type B aortic dissection (TBAD) may lead to long-term benefit, although the optimal treatment strategy is hotly debated. A robust comparison to outcomes seen in medically managed patients is challenging as the rate of antihypertensive medication adherence is unknown. The aims of this study were therefore to identify the rate of antihypertensive medication adherence and predictors of adherence in TBAD. This was a cross-sectional mixed methods study of patients with TBAD. Medication adherence was assessed by the eight-item Morisky Medication Adherence Scale together with an assessment of demographic, behavioral, and psychological variables and disease-specific knowledge. There were 47 patients (mean age, 59 years; 81% male) who were recruited from a tertiary vascular unit. The mean total number of medications taken was 5.8 (2-14), and the mean number of antihypertensive medications was 1.9 (1-6). Of the 47 patients, 20 (43%) reported high levels of medication adherence, 17 (36%) reported moderate adherence, and 10 (21%) reported low adherence. Previous aortic surgery was associated with higher levels of adherence (β = 0.332; P = .03), as was taking a greater number of medications (β = 0.332; P = .026), perceived benefit from treatment (β = 0.486; P < .001), good memory (β = 0.579; P < .001), and low fears of side effects (β = 0.272; P < .014). Medical management remains the mainstay of treatment in uncomplicated TBAD; however, the majority of patients are poorly adherent to their antihypertensive medications. The merits of thoracic endovascular aortic repair in TBAD are argued, and poor adherence is an important factor in the debate; one cannot robustly compare two strategies when half of a treatment group may not be receiving the stated intervention. To develop an evidence-based treatment strategy for TBAD, we must take into account the direct and indirect effects of medical therapy and thoracic endovascular aortic

To identify which factors best explain non-adherence to home rehabilitation exercises (HRE) for patients with musculoskeletal injuries. Cross-sectional study. Participants (n = 87) aged 17-91 years completed questionnaires measuring demographic and injury-related information, self-efficacy, personality, health locus of control, patient-practitioner relationship, optimism, health value and adherence to HRE. In addition, each participant's attending physiotherapist assessed the participant's adherence and effort during the appointment. A hierarchical regression with 3 steps (step 1: disposition; step 2: cognitive factors; step 3: patient-practitioner relationship) and adherence to HRE as the dependent variable was conducted. The factors in step 3 were the most significant and explained 16% (p < 0.001) of the variance in adherence to HRE. In addition, a high score for patient neuroticism was found to correlate with poor adherence to HRE. These preliminary results suggest that the patient-practitioner relationship is the best predictor of adherence to HRE, and that improving patient perception of the clinician's productivity, communication of information and trust during consultations may improve adherence to HRE.

Active drug use among HIV-infected persons is associated with poor adherence to highly active antiretroviral therapy (HAART) and suboptimal treatment outcomes. To understand adherence experiences among HIV-infected drug users, we conducted semistructured interviews with 15 participants in a randomized controlled trial evaluating the efficacy of directly observed HAART delivered in methadone maintenance clinics. Interviews were recorded, transcribed, and thematically analyzed. We identified negative and positive psychological themes associated with both drug use and adherence. Participants described tension between negative feelings (denial, shame, and perceived isolation) and positive feelings (acceptance, motivation, empowerment, and perceived connectedness), and they associated this tension with their own drug using and adherence behaviors. Sustained antiretroviral therapy adherence may require increased emphasis on understanding the psychological experience of HIV-infected drug users.

Antiretroviral (ARV) adherence is essential to prevent mother-to-child transmission of HIV. This study compared self-reported adherence versus ARV detection in dried blood spots (DBS) among N = 392 HIV-infected pregnant women in South Africa (SA). Women completed two self-reported adherence measures [visual analog scale (VAS), AIDS Clinical Trials Group Adherence (ACTG)]. Adherence was 89% (VAS), 80% (ACTG), and 74% (DBS). Self-report measures marginally agreed with DBS (VAS: Kappa = 0.101, Area under the ROC curve (AUROC) = 0.543; ACTG: Kappa  = 0.081, AUROC = 0.538). Self-reported adherence was overestimated and agreement with DBS was poor. Validation of self-reported ARV adherence among pregnant HIV+ women in SA is needed.

Introduction Every year, approximately 260,000 children are infected with HIV in low- and middle-income countries. The timely initiation and high level of maintenance of antiretroviral therapy (ART) are crucial to reducing the suffering of HIV-positive children. We need to develop a better understanding of the background of children's ART non-adherence because it is not well understood. The purpose of this study is to explore the background related to ART non-adherence, specifically in relation to the orphan status of children in Kigali, Rwanda. Methods We conducted 19 focus group discussions with a total of 121 caregivers of HIV-positive children in Kigali. The primary data for analysis were verbatim transcripts and socio-demographic data. A content analysis was performed for qualitative data analysis and interpretation. Results The study found several contextual factors that influenced non-adherence: among double orphans, there was psychological distance between the caregivers and children, whereas economic burden was the primary issue among paternal orphans. The factors promoting adherence also were unique to each orphan status, such as the positive attitude about disclosing serostatus to the child by double orphans’ caregivers, and feelings of guilt about the child's condition among non-orphaned caregivers. Conclusions Knowledge of orphan status is essential to elucidate the factors influencing ART adherence among HIV-positive children. In this qualitative study, we identified the orphan-related contextual factors that influenced ART adherence. Understanding the social context is important in dealing with the challenges to ART adherence among HIV-positive children. PMID:25477050

Perspectives Regarding Adherence to Prescribed Treatment in Highly Adherent HIV-Infected Gay Men.

2008-01-01

Focus group methodology was used to describe the medication adherence experience of 24 HIV-infected gay men who reported being adherent to their medication regimens. A conceptualization of medication adherence as an evolving process consisted of challenges to adherence (learning the diagnosis, starting the medications, struggling with the medications, dealing with side effects, coping with stigma) as well as those factors supportive of adherence (believing in medications, finding motivating factors, using reminders, depending on others, owning the disease). Themes associated with challenges to adherence focused on diagnosis and the physical and emotional adjustments individuals made to incorporate antiretroviral medications into their daily lives and move toward medication adherence. The factors supportive of adherence were related to the ongoing behaviors identified with establishing and maintaining adherence behaviors. What can be taken from the study is that adherence is a complex and dynamic process rather than a static behavior.

Compliance raises very specific questions in dermatology related to the frequent use of local treatments: creams or ointments, including topical corticosteroids. The adherence in dermatology is a complex issue. It is difficult to quantify objectively because of the patient subjectivity, the constant adaptation to changes in the course of the disease, and due to the lack of adapted device. Moreover poor compliance may be related to topical corticosteroid phobia, defined as a fear vis-à-vis the topical corticosteroids, rational or not. The topical corticosteroid phobia is very common in the management of chronic inflammatory skin diseases especially in atopic dermatitis. Copyright © 2012 Elsevier Masson SAS. All rights reserved.

Self-report is the most common method of measuring medication adherence but is influenced by recall error and response bias, and it typically does not provide insight into the causes of poor adherence. Ecological momentary assessment (EMA) of health behaviors using mobile phones offers a promising alternative to assessing adherence and collecting related data that can be clinically useful for adherence problem solving. To determine the feasibility of using EMA via mobile phones to assess adolescent asthma medication adherence and identify contextual characteristics of adherence decision making. We utilized a descriptive and correlational study design to explore a mobile method of symptom and adherence assessment using an interactive voice response system. Adolescents aged 12-18 years with a diagnosis of asthma and prescribed inhalers were recruited from an academic medical center. A survey including barriers to mobile phone use, the Illness Management Survey, and the Pediatric Asthma Quality of Life Questionnaire were administered at baseline. Quantitative and qualitative assessment of asthma symptoms and adherence were conducted with daily calls to mobile phones for 1 month. The Asthma Control Test (ACT) was administered at 2 study time points: baseline and 1 month after baseline. The sample consisted of 53 adolescents who were primarily African American (34/53, 64%) and female (31/53, 58%) with incomes US$40K/year or lower (29/53, 55%). The majority of adolescents (37/53, 70%) reported that they carried their phones with them everywhere, but only 47% (25/53) were able to use their mobile phone at school. Adolescents responded to an average of 20.1 (SD 8.1) of the 30 daily calls received (67%). Response frequency declined during the last week of the month (b=-0.29, P<.001) and was related to EMA-reported levels of rescue inhaler adherence (r= 0.33, P=.035). Using EMA, adolescents reported an average of 0.63 (SD 1.2) asthma symptoms per day and used a rescue

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.

The Family Smoking Prevention and Tobacco Control Act regulates the sales and marketing of tobacco products in the United States; poor adherence by tobacco retailers may reduce the effectiveness of the Act's provisions. The objectives of this study were 1) to assess whether and to which provisions retailers were adherent and 2) to examine differences in adherence by county, retailer neighborhood, and retailer characteristics. We conducted multivariate analysis of tobacco retailers' adherence to 12 point-of-sale provisions of the Tobacco Control Act in 3 North Carolina counties. We conducted observational audits of 324 retailers during 3 months in 2011 to assess adherence. We used logistic regression to assess associations between adherence to provisions and characteristics of each county, retailer neighborhood, and retailer. We found 15.7% of retailers did not adhere to at least 1 provision; 84.3% adhered to all provisions. The provisions most frequently violated were the ban on sales of cigarettes with modified-risk labels (eg, "light" cigarettes) (43 [13.3%] retailers nonadherent) and the ban on self-service for cigarettes and smokeless tobacco (6 [1.9%] retailers nonadherent). We found significant differences in rates of nonadherence by county and type of retailer. Pharmacies and drug stores were more than 3 times as likely as grocery stores to be nonadherent. Most tobacco retailers have implemented regulatory changes without enforcement by the US Food and Drug Administration. Monitoring rates of adherence by store type and locale (eg, county) may help retailers comply with point-of-sale provisions.

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.

Background Self-efficacy and the use of self-regulatory strategies are consistently associated with physical activity behavior. Similarly, behavioral inhibition and cognitive resource allocation, indices of executive control function, have also been associated with this health behavior. Purpose The purpose of this study was to examine the hypothesis that self-efficacy mediates the relationship between self-regulatory processes, such as executive function, and sustained exercise behavior. Methods Older adults (N = 177, mean age = 66.44 years) completed measures of executive function, self-reported use of self-regulatory strategies and self-efficacy prior to and during the first month of a 12-month exercise intervention. Percentage of exercise classes attended over the following 11 months was used to represent adherence. Data were collected from 2007 to 2010 and analyzed in 2010–2011. Structural equation models were tested examining the effect of executive function and strategy use on adherence via efficacy. Results As hypothesized, results showed significant direct effects of two elements of executive function and of strategy use on self-efficacy and of efficacy on adherence. In addition, there were significant indirect effects of strategy use and executive function on adherence via self-efficacy. Conclusions Higher levels of executive function and use of self-regulatory strategies at the start of an exercise program enhance beliefs in exercise capabilities, which in turn leads to greater adherence.

This review aims to provide an overview of the factors associated with adherence reported in existing literature on lifestyle modification programs for weight management among the adult population. An electronic search was performed using PubMed, Medline, PsycINFO and PsycARTICLE to identify studies that examined the factors of adherence to lifestyle modification programs with explicit definition of adherence indicators. We identified 19 studies published between 2004 and 2016. The most commonly used indicator of adherence was attrition, followed by attendance, self-monitoring and dietary adherence. A broad array of factors has been studied but only few studies exploring each factor. Limited evidence suggested older age, higher education, healthier eating and physical activity behaviours, higher stage of change at baseline and higher initial weight loss may predict better adherence. On the other hand, having depression, stress, strong body shape concern, more previous weight loss attempts and being unemployed may predict poor adherence. Inconsistent findings were obtained for self-efficacy, motivation and male gender. This review highlights the need for more rigorous studies to enhance our knowledge on factors related to adherence. Identification of the factors of adherence could provide important implication for program improvement, ultimately improving the effectiveness and the cost-effectiveness of lifestyle modification program.

Background Several technologies have been proposed to support the reduction of insomnia complaints. A user-centered assessment of these technologies could provide insight into underlying factors related to treatment adherence. Objective Gaining insight into adherence to technology-mediated insomnia treatment as a solid base for improving those adherence rates by applying adherence-enhancing strategies. Methods Adherence to technology-mediated sleep products was studied in three ways. First, a meta-analysis was performed to investigate adherence rates in technology-mediated insomnia therapy. Several databases were queried for technology-mediated insomnia treatments. After inclusion and exclusion steps, data from 18 studies were retrieved and aggregated to find an average adherence rate. Next, 15 semistructured interviews about sleep-support technologies were conducted to investigate perceived adherence. Lastly, several scenarios were written about the usage of a virtual sleep coach that could support adherence rates. The scenarios were discussed in six different focus groups consisting of potential users (n=15), sleep experts (n=7), and coaches (n=9). Results From the meta-analysis, average treatment adherence appeared to be approximately 52% (95% CI 43%-61%) for technology-mediated insomnia treatments. This means that, on average, half of the treatment exercises were not executed, suggesting there is a substantial need for adherence and room for improvement in this area. However, the users in the interviews believed they adhered quite well to their sleep products. Users mentioned relying on personal commitment (ie, willpower) for therapy adherence. Participants of the focus groups reconfirmed their belief in the effectiveness of personal commitment, which they regarded as more effective than adherence-enhancing strategies. Conclusions Although adherence rates for insomnia interventions indicate extensive room for improvement, users might not consider adherence to

Background Low health literacy is associated with poor outcomes in asthma and other diseases but the mechanisms governing this relationship are not well-defined. Objective To assess whether literacy is related to subsequent asthma self-management, measured as adherence to inhaled steroids, and asthma outcomes. Methods In a prospective longitudinal cohort study, numeric (Asthma Numeracy Questionnaire (ANQ)) and print literacy (Short Test of Functional Health Literacy in Adults (S-TOFHLA)) were assessed at baseline in adults with moderate or severe asthma for their impact on subsequent electronically monitored adherence and asthma outcomes (asthma control, asthma-related quality of life, and FEV1) over 26 weeks, using mixed-effects linear regression models. Results 284 adults participated: 48±14 years, 71% female, 70% African American, 6% Latino, mean FEV1 66% ± 19%, 86 (30%) with hospitalizations and 148 (52%) with ED visits for asthma in the prior year. Mean ANQ score (range 0–4) was 2.3 ± 1.2; mean S-TOFHLA score 31 ± 8 (range 0–36). In unadjusted analyses numeric and print literacy were associated with better adherence (p=0.01, p=0.08), asthma control (p=0.005, p <0.001), and quality of life (p<0.001, p<0.001). After controlling for age, sex, and race/ethnicity, the associations diminished and only quality of life (numeric: p=0.03, print p=0.006) and asthma control (print p=0.005) remained significantly associated with literacy. Race/ethnicity, income, and educational attainment were correlated (p<0.001). Conclusion While the relationship between literacy and health is complex, interventions which account for and address the literacy needs of patients may improve asthma outcomes. Clinical Implications/Key Summary In adults with moderate or severe asthma, higher health literacy scores were associated with better subsequent quality of life and asthma control. PMID:23591273

2015-05-01

Patient adherence to voice therapy is an established challenge. The purpose of this study was (a) to examine whether adherence to treatment could be predicted from three social-cognitive factors measured at treatment onset: self-efficacy, goal commitment, and the therapeutic alliance, and (b) to test whether the provision of clinician, self-, and peer model mobile treatment videos on MP4 players would influence the same triad of social cognitive factors and the adherence behavior of patients. Forty adults with adducted hyperfunction with and without benign lesions were prospectively randomized to either 4 sessions of voice therapy enhanced by MP4 support or without MP4 support. Adherence between sessions was assessed through self-report. Social cognitive factors and voice outcomes were assessed at the beginning and end of therapy. Utility of MP4 support was assessed via interviews. Self-efficacy and the therapeutic alliance predicted a significant amount of adherence variance. MP4 support significantly increased generalization, self-efficacy for generalization, and the therapeutic alliance. An interaction effect demonstrated that MP4 support was particularly effective for patients who started therapy with poor self-efficacy for generalization. Adherence may be predicted and influenced via social-cognitive means. Mobile technology can extend therapy to extraclinical settings.

Background HIV-infected refugees resettled in the United States face many challenges. Longitudinal data regarding HIV-specific outcomes in this population are limited. Methods We reviewed charts of 51 HIV-infected sub-Saharan African refugees matched to 102 nonrefugees. Outcomes analyzed included CD4 counts, viral loads (VLs), antiretroviral treatment (ART) use, appointment adherence, opportunistic infections, and resistance mutations. Results The ART initiation was similar. Appointment adherence was similar in year 1, but refugees were significantly less adherent beyond year 3. Refugees and nonrefugees spent similar amounts of time in care suppressed (83% vs 80%, P = .93). Refugees had higher odds of viremia following undetectable VL (OR 2.3, P < .05). Discussion Initially, sub-Saharan African HIV-infected refugees have comparable appointment adherence, ART use, and VL suppression to nonrefugees. Overtime refugees were less adherent to appointments and more likely to have postsuppression viremia. The support services provided to refugees early in care may be important for retention in care and treatment success. PMID:23024042

Poor adherence to inhaled corticosteroids (ICS) is a critical risk factor contributing to asthma morbidity among low-income minority adolescents. This trial tested whether peer support group meetings and peer asthma messages delivered via mp3 players improved adherence to ICS. Low-income African American and/or Hispanic adolescents, ages 11-16 years old, with persistent asthma, and poor (≤ 48%) adherence to prescription ICS during the 3-week run-in were randomized to intervention or attention control groups (ATG) for the 10-week treatment. During treatment, the intervention arm subjects participated in weekly coping peer group support sessions and received mp3 peer-recorded asthma messages that promoted adherence. The ATG participated in weekly meetings with a research assistant and received an equivalent number of mp3 physician-recorded asthma messages. Adherence was measured by using self-report and the Doser CT, an electronic dose counter. The primary outcome was the difference in adherence at 10 weeks between the 2 arms. Thirty-four subjects were randomized to each arm. At 10 weeks, no statistical difference in objectively measured adherence could be detected between the 2 arms when adjusting for baseline adherence (P = .929). Adherence declined in both groups over the course of the active treatment period. In both study arms, self-reported adherence by participants was significantly higher than their objectively measured adherence at week 10 (P < .0001). Improving medication adherence in longitudinal studies is challenging. Peer support and mp3-delivered peer asthma messages may not be of sufficient dose to improve outcomes.

This article presents the development of a new 82-item rating scale of therapist adherence and competence for supportive-expressive (SE) dynamic psychotherapy for the treatment of cocaine dependence. Sixty- four items are rated for adherence, appropriateness, and quality of prescribed interventions. As part of the pilot/training phase of the National Institute on Drug Abuse Collaborative Cocaine Treatment Study, two independent expert judges rated 32 audiotapes of SE therapy sessions with cocaine-dependent patients, 10 tapes of cognitive therapy (CT) sessions, and 10 tapes of individual drug counseling (IDC) sessions. Reliability was acceptable for adherence but poor for quality and appropriateness. SE therapists used more expressive (interpretative) techniques than did either CT therapists or IDC counselors, and they used more supportive techniques than did IDC counselors. PMID:9058557

Background There is currently no gold standard for assessing antiretroviral (ARV) adherence, so researchers often resort to the most feasible and cost-effective methods possible (eg, self-report), which may be biased or inaccurate. The goal of our study was to evaluate the feasibility and acceptability of innovative and remote methods to estimate ARV adherence, which can potentially be conducted with less time and financial resources in a wide range of clinic and research settings. Here, we describe the research protocol for studying these novel methods and some lessons learned. Methods The 6-month pilot study aimed to examine the feasibility and acceptability of a remotely conducted study to evaluate the correlation between: 1) text-messaged photographs of pharmacy refill dates for refill-based adherence; 2) text-messaged photographs of pills for pill count-based adherence; and 3) home-collected hair sample measures of ARV concentration for pharmacologic-based adherence. Participants were sent monthly automated text messages to collect refill dates and pill counts that were taken and sent via mobile telephone photographs, and hair collection kits every 2 months by mail. At the study end, feasibility was calculated by specific metrics, such as the receipt of hair samples and responses to text messages. Participants completed a quantitative survey and qualitative exit interviews to examine the acceptability of these adherence evaluation methods. The relationship between the 3 novel metrics of adherence and self-reported adherence will be assessed. Discussion Investigators conducting adherence research are often limited to using either self-reported adherence, which is subjective, biased, and often overestimated, or other more complex methods. Here, we describe the protocol for evaluating the feasibility and acceptability of 3 novel and remote methods of estimating adherence, with the aim of evaluating the relationships between them. Additionally, we note the lessons

Drug-related problems are very common and they need some specific attention. Improper use of medication as well as poor adherence leads to side effects, interaction, increased healthcare costs,... What technologies can be used in community pharmacies to improve drug adherence? Articles were found in scientific databases Pubmed, Embase and CINAHL using a fixed search strategy. In this review 21 studies were included. The different technologies were compared with each other. Reminders using sms or smartphone were the most effective. There are already plenty of reminder systems (SMS, Email, internet, smartphone) and practical tools (medication dispensers, MEMS) available in community pharmacies. A major hurdle is the lack of the infrastructure. There needs to be invested in systems were patients are confronted with their own drug use.

Despite evidence of a positive effect of collaborative patient-provider communication on patient outcomes, our understanding of this relationship is unclear. The purpose of this paper is to determine whether racial composition of the relationship modified the association between ratings of provider communication and medication adherence. Effect modification of the communication-adherence association, by racial composition of the relationship, was evaluated using general linear mixed models while adjusting for selected covariates. Three hundred ninety patients were in race-concordant (black patient, black provider) relationships, while 207 were in race-discordant (black patient, white provider) relationships. The communication-adherence association was significantly modified in race-discordant relationships (p = 0.04). Communication rated as more collaborative in race-discordant relationships was associated with better adherence, while communication rated as less collaborative was associated with poor adherence. There was no significant association between adherence and communication in race-concordant relationships (p = 0.24). Collaborative patient-provider communication may play an influential role in black patients' adherence behaviors when receiving care from white providers.

Background and Objectives Patient adherence to psychosocial treatment is an important but understudied topic. The aim of this study was to examine whether better patient recall of treatment contents and therapist use of memory support (MS) were associated with better treatment adherence. Methods Data were drawn from a pilot randomized controlled trial. Participants were 48 individuals (mean age = 44.27 years, 29 females) with Major Depressive Disorder randomized to receive either Cognitive Therapy (CT) with an adjunctive Memory Support Intervention (CT+Memory Support) or CT-as-usual. Therapist and patient ratings of treatment adherence were collected during each treatment session. Patient recall was assessed at mid-treatment. Therapist use of MS was manually coded for a random selection of sessions. Results Patient recall was significantly associated with better therapist and patient ratings of adherence. Therapist use of Application, a specific MS strategy, predicted higher therapist ratings of adherence. Attention Recruitment, another specific MS strategy, appeared to attenuate the positive impact of session number on patient ratings of adherence. Treatment groups, MS summary scores and other specific MS strategies were not significantly associated with adherence. Limitations The measure for treatment adherence is in the process of being formally validated. Results were based on small sample. Conclusions These results support the importance of patient recall in treatment adherence. Although collectively the effects of MS on treatment adherence were not significant, the results support the use of certain specific MS strategy (i.e., application) as a potential pathway to improve treatment adherence. Larger-scale studies are needed to further examine these constructs. PMID:27614662

The Influence of Chronic Ego Depletion on Goal Adherence: An Experience Sampling Study.

Although ego depletion effects have been widely observed in experiments in which participants perform consecutive self-control tasks, the process of ego depletion remains poorly understood. Using the strength model of self-control, we hypothesized that chronic ego depletion adversely affects goal adherence and that mental effort and motivation are involved in the process of ego depletion. In this study, 203 students reported their daily performance, mental effort, and motivation with respect to goal directed behavior across a 3-week time period. People with high levels of chronic ego depletion were less successful in goal adherence than those with less chronic ego depletion. Although daily effort devoted to goal adherence increased with chronic ego depletion, motivation to adhere to goals was not affected. Participants with high levels of chronic ego depletion showed a stronger positive association between mental effort and performance, but chronic ego depletion did not play a regulatory role in the effect of motivation on performance. Chronic ego depletion increased the likelihood of behavior regulation failure, suggesting that it is difficult for people in an ego-depletion state to adhere to goals. We integrate our results with the findings of previous studies and discuss possible theoretical implications.

Association of Race Consciousness With the Patient–Physician Relationship, Medication Adherence, and Blood Pressure in Urban Primary Care Patients

PubMed Central

2013-01-01

BACKGROUND Race consciousness (the frequency with which one thinks about his or her own race) is a measure that may be useful in assessing whether racial discrimination negatively impacts blood pressure (BP). However, the relation between race consciousness and BP has yet to be empirically tested, especially within the context of the patient–physician relationship and medication adherence. METHODS Race-stratified generalized estimating equations were used to assess the relationship of race consciousness on BP, measures of the patient–physician relationship, and self-reported medication adherence, controlling for patients being nested within physicians and for patient age and sex. RESULTS The mean age of the patients was 61.3 years, 62% were black, and 65% were women. Black patients were more likely to ever think about race than were white patients (49% vs. 21%; P < 0.001). Race-conscious blacks had significantly higher diastolic BP (79.4 vs. 74.5mm Hg; P = 0.004) and somewhat higher systolic BP (138.8 vs. 134.7mm Hg; P = 0.13) than blacks who were not race conscious. Race-conscious whites were more likely to perceive respect from their physician (57.1% vs. 25.8%; P = 0.01) but had lower medication adherence (62.4% vs. 82.9%; P = 0.05) than whites who were not race-conscious. CONCLUSIONS Among blacks, race consciousness was associated with higher diastolic BP. In contrast, among whites, there was no association between race consciousness and BP, but race consciousness was associated with poor ratings of adherence, despite more favorable ratings of the patient–physician relationship. Future work should explore disparities in race consciousness and its impact on health and health-care disparities. PMID:23864583

Relationship between adherence to diet, glycemic control and cardiovascular risk factors in patients with type 1 diabetes: a nationwide survey in Brazil

PubMed Central

2014-01-01

Background To determine the relationship between adherence to the diet reported by patients with type 1 diabetes under routine clinical care in Brazil, and demographic, socioeconomic status, glycemic control and cardiovascular risk factors. Methods This was a cross-sectional, multicenter study conducted between December 2008 and December 2010 in 28 public clinics in 20 Brazilian cities. The data was obtained from 3,180 patients, aged 22 ± 11.8 years (56.3% females, 57.4% Caucasians and 43.6% non-Caucasians). The mean time since diabetes diagnosis was 11.7 ± 8.1 years. Results Overall, 1,722 (54.2%) of the patients reported to be adherent to the diet without difference in gender, duration of diabetes and socioeconomic status. Patients who reported adherence to the diet had lower BMI, HbA1c, triglycerides, LDL-cholesterol, non HDL-cholesterol and diastolic blood pressure and had more HbA1c at goal, performed more frequently self-monitoring of blood glucose (p < 0.001), and reported less difficulties to follow specific schedules of diet plans (p < 0.001). Less patients who reported to be adherent were obese or overweight (p = 0.005). The quantity of food and time schedule of the meals were the most frequent complaints. Logistic regression analysis showed that ethnicity, (Caucasians, (OR 1.26 [1.09-1.47]), number of medical clinical visits in the last year (OR 1.10 [1.06-1.15]), carbohydrate counting, (OR 2.22 [1.49-3.30]) and diets recommended by diabetes societies’, (OR 1.57 [1.02-2.41]) were related to greater patients’ adherence (p < 0.05) and age, [adolescents (OR 0.60 [0.50-0.72]), high BMI (OR 0.58 [0.94-0.98]) and smoking (OR 0.58 [0.41-0.84]) with poor patients’ adherence (p < 0.01). Conclusions Our results suggest that it is necessary to rethink medical nutrition therapy in order to help patients to overcome barriers that impair an optimized adherence to the diet. PMID:24607084

Poor adherence to factor replacement therapy among patients with haemophilia can lead to joint bleeding and eventual disability. The aim of this study was to determine patient-related characteristics associated with adherence to factor replacement in adults with haemophilia. Adults with haemophilia were recruited to participate in this cross-sectional study. Adherence was measured using either the Validated Hemophilia Regimen Treatment Adherence Scale (VERITAS)-Pro or the VERITAS-PRN questionnaire. Simple and multiple regression analyses that controlled for confounding were performed to determine the association between patient-related characteristics and adherence to factor replacement therapy. Of the 99 subjects enrolled, all were men; 91% had haemophilia A and 78% had severe disease. Age ranged from 18 to 62 years. Most (95%) had functional health literacy; but only 23% were numerate. Mean adherence scores were 45.6 (SD 18) and 51.0 (SD 15) for those on a prophylactic and those on an episodic regimen, respectively, with a lower score indicating better adherence. On multivariable analysis, being on any chronic medication, longer duration followed at our haemophilia treatment centre, higher physician trust and better quality of life were associated with higher adherence. A history of depression was associated with lower adherence. Two potentially modifiable characteristics, physician trust and depression, were identified as motivator and barrier to adherence to factor replacement therapy. Promoting a high level of trust between the patient and the healthcare team as well as identifying and treating depression may impact adherence to factor replacement therapy and accordingly reduce joint destruction. © 2016 John Wiley & Sons Ltd.

Behavioral Health Care for Adolescents with Poorly Controlled Diabetes via Skype: Does Working Alliance Remain Intact?

Freeman, Kurt A.; Duke, Danny C.; Harris, Michael A.

2013-01-01

Background: Increasingly various technologies are being tested to deliver behavioral health care. Delivering services via videoconferencing shows promise. Given that the patient–provider relationship is a strong predictor of patient adherence to medical regimens, addressing relationship quality when services are not delivered face-to-face is critical. To that end, we compared the therapeutic alliance when behavioral health care was delivered to youth with poorly controlled type 1 diabetes mellitus (T1DM) and their caregivers in-clinic with the same services delivered via Internet-based videoconferencing (i.e., Skype™). Methods: Seventy-one adolescents with poorly controlled T1DM (hemoglobin A1c ≥9%) and one of their caregivers received up to 10 sessions of a family-based behavioral health intervention previously shown to improve adherence to diabetes regimens and family functioning; 32 were randomized to the Skype condition. Youth and caregivers completed the working alliance inventory (WAI), a 36-item measure of therapeutic alliance, at the end of treatment. Additionally, the number of behavioral health sessions completed was tracked. Results: No significant differences in WAI scores were found for those receiving behavioral health care via Skype versus in-clinic. Youth WAI goal and total scores were significantly associated with the number of sessions completed for those in the clinic group. Conclusion: Behavioral health can be delivered to youth with T1DM via Internet-based videoconferencing without significantly impacting the therapeutic relationship. Thus, for those adolescents with T1DM who require specialized behavioral health care that targets T1DM management, Internet-based teleconferencing represents a viable alternative to clinic-based care.

Many patients with diabetes have poor blood pressure (BP) control. Pharmacological therapy is the cornerstone of effective BP treatment, yet there are high rates both of poor medication adherence and failure to intensify medications. Successful medication management requires an effective partnership between providers who initiate and increase doses of effective medications and patients who adhere to the regimen. In this cluster-randomized controlled effectiveness study, primary care teams within sites were randomized to a program led by a clinical pharmacist trained in motivational interviewing-based behavioral counseling approaches and authorized to make BP medication changes or to usual care. This study involved the collection of data during a 14-month intervention period in three Department of Veterans Affairs facilities and two Kaiser Permanente Northern California facilities. The clinical pharmacist was supported by clinical information systems that enabled proactive identification of, and outreach to, eligible patients identified on the basis of poor BP control and either medication refill gaps or lack of recent medication intensification. The primary outcome is the relative change in systolic blood pressure (SBP) measurements over time. Secondary outcomes are changes in Hemoglobin A1c, low-density lipoprotein cholesterol (LDL), medication adherence determined from pharmacy refill data, and medication intensification rates. Integration of the three intervention elements--proactive identification, adherence counseling and medication intensification--is essential to achieve optimal levels of control for high-risk patients. Testing the effectiveness of this intervention at the team level allows us to study the program as it would typically be implemented within a clinic setting, including how it integrates with other elements of care. The ClinicalTrials.gov registration number is NCT00495794.

The purpose of this study was to identify key psychosocial characteristics of HIV-infected women who exhibit different levels of both ART adherence and risk behaviors. We analyzed baseline data from 193 predominately African American HIV-infected women participating in a behavioral clinical trial. Women were categorized into high/low groups based on levels of adherence and risky behaviors. There was a significant interaction effect for internal motivation for adherence. Women at high risk for poor health and transmitting HIV (low adherence/high risk group) had the lowest levels of internal motivation and also reported more difficult life circumstances. Gender roles, caretaking and reliance on men for economic and other support may promote external versus internal motivation as well as riskier behaviors in this group. The highest levels of internal motivation were found in those with High Adherence/High Risk behaviors. This group was highly knowledgeable about HIV and had the lowest VL. Compared to others, this group seems to tolerate risky behaviors given their high level of adherence. Adherence and risk reduction behaviors are key to individual and public health. Motivation and risk compensation should be addressed when providing interventions to women living with HIV. PMID:26452670

Physical and emotional scarring are equally important burdens of acne vulgaris in patients of any age. Effective therapeutic regimens are readily available, and the consistent and correct use of these medications results in effective disease management, reduced risk for scarring, as well as improvement in various factors that affect quality of life. Nevertheless, adherence to treatment recommendations generally is poor. Clinicians can help improve adherence with a variety of strategies, including counseling, education, and choosing treatment options that are most consistent with a patient's lifestyle.

Current international guidelines recommend 6-9 months of isoniazid (INH) preventive chemotherapy to prevent the development of active tuberculosis (TB) in susceptible children exposed to Mycobacterium tuberculosis. However, this is dependent on good adherence, as shown by previous studies. This study was conducted to describe the outcome of screening of contact children aged 5 years or less with household exposure to an adult pulmonary TB index case to determine the prevalence and possible risk factors of infection among contact children and to determine the extent and outcome of adherence of contact children to unsupervised INH chemoprophylaxis for 6 months. A descriptive facility-based cross-sectional study was conducted from March 2009 to August 2010. Research settings were three of the National TB control program chest dispensaries (primary care facilities) in Alexandria, Egypt. Facility-based TB treatment registers of the previous 3 months were used to identify all new adult pulmonary TB cases. All children aged 5 years or less living in the same house as the index cases were identified and screened for TB. The contact children were given unsupervised INH preventive chemotherapy once active TB was excluded. Adherence to and outcome of preventive chemotherapy were followed up. Preventive chemotherapy consisted of unsupervised INH monotherapy for 6 months with monthly collection of tablets from the clinic. Adherence was documented after completion of the 6-month preventive treatment period. Adherence was considered reasonable if tablets were collected for more than 4 months, poor if collected for 2-4 months, and very poor if collected for less than 2 months. (a) Prevalence of infection and disease and the possible risk factors among contacts. (b) The extent and outcome of adherence to unsupervised INH chemoprophylaxis among contact children.

Although the number of people receiving antiretroviral therapy (ART) in Indonesia has increased in recent years, little is known about the specific characteristics affecting adherence in this population. Indonesia is different from most of its neighbors given that it is a geographically and culturally diverse country, with a large Muslim population. We aimed to identify the current rate of adherence and explore factors that influence ART adherence. Data were collected from ART-prescribed outpatients on an HIV registry at a North Jakarta hospital in 2012. Socio-demographic and behavioral characteristics were explored as factors associated with adherence using logistics regression analyses. Chi squared test was used to compare the difference between proportions. Reasons for missing medication were analyzed descriptively. Two hundred and sixty-one patients participated, of whom 77% reported ART adherence in the last 3 months. The level of social support experienced was independently associated with adherence where some social support (p = 0.018) and good social support (p = 0.039) improved adherence compared to poor social support. Frequently cited reasons for not taking ART medication included forgetting to take medication (67%), busy with something else (63%) and asleep at medication time (60%). This study identified that an increase in the level of social support experienced by ART-prescribed patients was positively associated with adherence. Social support may minimize the impact of stigma among ART prescribed patients. Based on these findings, if social support is not available, alternative support through community-based organizations is recommended to maximize treatment success.

In 2001, the North Carolina (NC) Medicaid program reduced the number of days prescription supply that enrollees could fill from 100 days to 34 days and increased copayments for brand-name medications. Previous work has shown that a change in these policies led to a decrease in medication adherence from 2.9 to 8.0 percentage points in specific populations with chronic conditions. Studies have also shown that days supply limits and copayment increases have heterogeneous effects based on enrollees' baseline characteristics, including baseline adherence. However, this phenomenon has not been studied in the Medicaid population. We undertook this study to assess the heterogeneous effect of the NC Medicaid policy changes in groups with varying levels of baseline adherence. To examine whether restrictions on days supply had heterogeneous effects in subgroups defined by medication adherence before the policy changes. A partial difference-in-difference-in-differences model with fixed effects was used to compare medication adherence before and after the NC Medicaid policy changes among Medicaid enrollees subject to the policy changes because of their use of long prescriptions (> 40 days) as compared with (a) NC Medicaid enrollees using short prescriptions (< 40 days) before policy adoption, as well as (b) Medicaid enrollees in Georgia restricted to a 31 days supply through the study period. Medicaid enrollees were included if they filled a prescription for 1 of the following medication classes: antihypertensives, lipid-lowering drugs, or antipsychotics. The effect of the policy changes on medication adherence, calculated using the proportion of days covered (PDC) each quarter by baseline adherence level and clinical condition group, was studied. Average adherence levels over the 18-month prechange period were used to stratify individuals into 3 baseline adherence groups: fully adherent (PDC ≥ 80%), partially adherent (50%-79%), and nonadherent (PDC ≤ 50%).

The need for a correct follow-up for medical advices of health givers is the cornerstone for avoiding drug-related complications in especial period of elderly people life. There isn't any data about drug therapy regimens adherence of elderly people of Isfahan. In this study, we aimed to cover this deficit. In this cross-sectional study which was carried out in Isfahan (Iran) in 2013 senior citizens (aged 65 or more) who were taking at least one medication and had no record of residency in nursing homes were included. We used Morisky medication adherence scale (after validation and reliability assessment for using this questionnaire in Persian language) to evaluate the level of adherence in the study population. A total of 200 elderly participants were fully studied ( n = 200, 61% females), and 52% of them had poor medication adherence. 77.5% of participants were suffered from at least four medical illnesses, and 18.5% of them were taking more than eight medications per day. We have not found any significant statistical relationship between vision or hearing loss disorders and the medication adherence of the participants). There was a significant positive relationship between the level of education and medication adherence ( P = 0.001), ( χ 2 = 0.29). Low Medication adherence is a common and important drug issue in the elderly in Isfahan. This issue can lead to medical complications and huge cost if it is not addressed appropriately.

Adolescents have gained increased attention because they are the only age group where HIV related mortality is going up. We set out to describe the level and factors associated with adherence to antiretroviral therapy (ART) as well as the 1 year retention in care among adolescents in 10 representative districts in Uganda. In addition, we explored the barriers and facilitators of adherence to ART among adolescents. The study involved 30 health facilities from 10 representative districts in Uganda. We employed both qualitative and quantitative data collection methods in convergent design. The former involved Focus group discussions with adolescents living with HIV, Key informant interviews with various stakeholders and in depth interviews with adolescents. The quantitative involved using retrospective records review to extract the last recorded adherence level from all adolescents who were active in HIV care. Factors associated with adherence were extracted from the ART cards. For the 1 year retention in care, we searched the hospital records of all adolescents in the 30 facilities who had started ART 1 year before the study to find out how many were still in care. Out of 1824 adolescents who were active on ART, 90.4 % (N = 1588) had ≥95 % adherence recorded on their ART cards at their last clinic visit. Only location in rural health facilities was independently associated with poor adherence to ART (P = 0.008, OR 2.64 [1.28 5.43]). Of the 156 adolescents who started ART, 90 % (N = 141) were still active in care 1 year later. Stigma, discrimination and disclosure issues were the most outstanding of all barriers to adherence. Other barriers included poverty, fatigue, side effects, pill burden, depression among others. Facilitators of adherence mainly included peer support groups, counseling, supportive health care workers, short waiting time and provision of food and transport. Adherence to ART was good among adolescents. Being in rural areas was associated with

Failure to comply with treatment recommendations is very common in patients, but still poorly recognised by doctors. The current practice of using oral therapy on a large scale has been increasingly adopted for cancer patients. Chronic myeloid leukaemia (CML) is just such an example, where the introduction of taking new oral medications, the tyrosine kinase BCR-ABL inhibitors (TKI), has now revolutionised the treatment. The aim of our study was to assess treatment adherence in a group of Polish CML patients (a survey was conducted on 140 patient aged ≥18 years) treated with oral TKI (imatinib, dasatinib and nilotinib) taking into account the following variables: gender, age, education, place of residence, family circumstances and duration of therapy. In addition, we evaluated whether there is a relationship between how patients perceive their level of adherence to treatment recommendations with how subjectively the required dosage regimen was followed. Half the patients admitted to skipping at least one drug dose during the entire course of treatment and 39% did so within their last treatment month. Patients were also found to overestimate their own adherence assessment; around 60% of those missing at least 1 drug dose within the last treatment month believed they 'always' followed recommendations. The study demonstrated that adherence deteriorates over time. Furthermore, patients aged >65 years and patients suffering at least one comorbid disease had better adherence (p < 0.011). There were no differences in adherence among patients treated with imatinib, dasatinib and nilotinib (p = 0.249).

Treatment adherence is a widely recognized problem in health services but understudied in caregiver intervention research. This study examines caregiver sociodemographic and psychological characteristics, patient illness severity, and treatment implementation factors as predictors of caregiver adherence to a skills training intervention to help families manage dementia care problems at home. The sample consisted of 105 caregivers randomized to the Home Environmental Skill-Building Program at the Philadelphia site of the National Institutes of Health (NIH) Resources for Enhancing Alzheimer's Caregiver Health (REACH I). The intervention, implemented by occupational therapists, consisted of education, problem solving, communication, environmental and task simplification techniques, and home modifications. Adherence was measured by a proportion score representing the percentage of strategies used by participants compared to the total number of strategies prescribed during intervention (Strategy Use). Regression analysis with intraclass correlation adjustment for interventionist effects revealed that caregivers with better physical health (p <.001), greater treatment exposure (p <.001), more problem areas addressed (p =.012), and for whom more active therapeutic techniques (role play) were used (p =.004) demonstrated greater adherence. Other caregiver characteristics, patient cognitive impairment, and troublesome behaviors were not significantly related to caregiver adherence. Modifiable caregiver and treatment implementation factors, including active engagement of caregivers, were associated with adherence, whereas patient characteristics were not. Caregivers with poor health may be at risk for not benefiting from intervention, suggesting that efforts, including instruction in preventive care and allocating time to attend to their own health care needs, be directed towards improving their health.

Background Warfarin is an anticoagulant effective in preventing stroke, but it has a narrow therapeutic range requiring optimal adherence to achieve the most favorable effects. Purpose The goal of this study was to examine specific patient factors that might help explain warfarin non-adherence at outpatient anticoagulation clinics. Method In a prospective cohort study of 156 adults, we utilized logistic regression analyses to examine the relationship between the five Treatment Prognostics scales from the Millon Behavioral Medicine Diagnostic (MBMD), as well as three additional MBMD scales (Depression, Future Pessimism, and Social Isolation), and daily warfarin non-adherence assessed using electronic medication event monitoring systems caps over a median of 139 days. Results Four of the five Treatment Prognostic scales and greater social isolation were associated with warfarin non-adherence. When controlling for pertinent demographic and medical variables, the Information Discomfort scale remained significantly associated with warfarin non-adherence over time. Conclusion Although several factors were related to warfarin non-adherence, patients reporting a lack of receptivity to details regarding their medical illness seemed most at risk for warfarin non-adherence. This information might aid in the development of interventions to enhance warfarin adherence and perhaps reduce adverse medical events. PMID:19579066

Although adherence to hemodialysis (HD) regimes is important to maximise good clinical outcomes, it remains suboptimal and not well understood, particularly for those in non-Western settings and patients from Asian cultures. This qualitative study sought to explore cultural perspectives on facilitators and barriers to treatment adherence in HD patients. A descriptive exploratory design was used for the study, incorporating individual semi-structured interviews (n = 17) and three focus groups (n = 20). Each interview/focus group was audio-taped and transcribed verbatim, and coding was conducted by two coders using an iterative process. Study participants identified personal and social/contextual factors as major barriers or facilitators of treatment adherence. Barriers include time consumption, forgetfulness, concerns about safety, poor knowledge/understanding, poor communication and lack of control/social pressure. Participants also identified facilitators, both internal (self-initiated) and external (initiated by family, health care professional and peers) to ensure treatment adherence. These included support from family members and social obligation towards others, risk perception, establishment of routines and peer support. Internal and external factors can hinder or facilitate adherence to diet, fluid and medications in the context of dialysis. Several of these barriers/facilitators can be effectively addressed in the context of interventions and psycho-educational programmes.

Diabetes therapeutic education and information by leaflets is important. This study aimed to understand the effectiveness of written information to diabetic patients, after six months, in the control of diabetes and medication adherence. Non-pharmacological clinical trial. Randomized sample of diabetic patients of 65 volunteer doctors, distributed among the five health regions in Portugal. At the first appointment, patients were randomized in four groups (three intervention with validated leaflets and one control), leaflet reading being reinforced at the follow-up appointments in a 6-months period. Variables collected: HbA1c, home blood glucose, weight, waist circumference, blood pressure, cigarettes smoked, physical activity level, adherence to medication, medication, height, diabetes progression, age, sex and educational background. Descriptive and inferential statistics. From the 709 patients recruited, 702 were studied in this 6-months period with no statistical differences in the baseline variables studied. After six months of intervention, the adherence to medication improved in the leaflet group (p=0.034). This was noticed in those under 65 years of age (p=0.027), with diabetes for ≤ 5 years (p=0.010), with educational background up to 4 years (p=0.030) and 9 years (p=0.006) and with HbA1c ≥ 7% at the beginning of the study. Interventions with leaflets handed in primary healthcare to people with diabetes type 2 can bring benefits in what concerns adherence to therapeutics, namely in younger people with a less studies.

Despite the set guidelines on Healthcare Waste Management in Kenya, mixing of different categories of waste, crude dumping and poor incineration are still a common phenomenon in public health facilities in Thika Subcounty, Kenya. Thika Subcounty generates 560 Kilograms of healthcare waste daily, which is risk to the many patients (admission rate of 26%). This may pose a potential environmental risk and be a source of disease diffusion. This research explored the adherence to healthcare waste management waste guidelines in health care facilities among the nurses and waste handlers. This was a cross sectional survey in which mixed methods were applied. A census and proportionate random sampling method were used. Quantitative data was analyzed using Statistical Package for Social Science (SPSS) version 20.0, while qualitative data was analyzed manually into themes. Full adherence to the seven waste disposal guidelines was low (16.3%). Knowledge on waste segregation, waste separation then disposal and means of transports were statistically significant in relation to adherence. The type of incinerator and burning status, protection maintenance and supply of adequate waste bins were also important to adherence level. Adherence level was low (16.3%,) and insignificantly different among nurses and waste handlers. From this finding, compliance remains a key challenge. Strategies targeted at contextualizing waste regulations and guidelines into local settings are necessary and important. Policy makers may design and implement standard incinerators across all the health facilities. This study is not exhaustive; therefore, it is necessary to carry out a study linking poor treatment and disposal of clinical waste to purported health outcomes in Kenya.

Middle-aged African American women have the highest incidence and mortality of invasive cervical cancer in the United States and the lowest adherence to pap smear screening. In 2001, we identified factors associated with non-adherence to screening recommendations using three focus group interviews and subsequently developed a questionnaire administered to 144 African American women aged 45 to 65 years. The perception that the Pap test was painful was associated with non-adherence to screening recommendations (OR = 4.78; 95%CI: 1.67-13.7). Difficulty to pay for the office visit coupled with perceived pain was associated with a nearly sixfold increase in risk of non-adherence (OR = 5.8; 95%CI: 2.8-15.5). Previously identified barriers to screening including lower education and socioeconomic status, poor access to care, knowledge of and exposure to known risk factors of invasive cervical cancer, cancer fatalism, and perceived racism were not independently associated with non-adherence. These data suggest that, among middle-aged African American women, future interventions addressing pain during a Pap test will likely increase acceptability of and adherence to cervical cancer screening. Pain could be addressed either by providing information during the pap test and/or using smaller lubricated speculums.

Purpose: We report demographic, clinical, and psychosocial factors associated with adherence to vaginal dilation and describe the sexual and marital or nonmarital dyadic functioning of women following high dose rate (HDR) brachytherapy for endometrial cancer. Methods and Materials: We retrospectively evaluated women aged 18 years or older in whom early-stage endometrial (IAgr3-IIB) cancers were treated by HDR intravaginal brachytherapy within the past 3.5 years. Women with or without a sexual partner were eligible. Patients completed questionnaires by mail or by telephone assessing demographic and clinical variables, adherence to vaginal dilation, dyadic satisfaction, sexual functioning, and health beliefs. Results: Seventy-eight ofmore » 89 (88%) eligible women with early-stage endometrial cancer treated with HDR brachytherapy completed questionnaires. Only 33% of patients were adherers, based on reporting having used a dilator more than two times per week in the first month following radiation. Nonadherers who reported a perceived change in vaginal dimension following radiation reported that their vaginas were subjectively smaller after brachytherapy (p = 0.013). Adherers reported more worry about their sex lives or lack thereof than nonadherers (p = 0.047). Patients reported considerable sexual dysfunction following completion of HDR brachytherapy. Conclusions: Adherence to recommendations for vaginal dilator use following HDR brachytherapy for endometrial cancer is poor. Interventions designed to educate women about dilator use benefit may increase adherence. Although sexual functioning was compromised, it is likely that this existed before having cancer for many women in our study.« less

Background Effective interventions to improve medication adherence are usually complex and expensive. Objective To assess the impact of a low-cost intervention designed to improve medication adherence and clinical outcomes in post-discharge patients with CVD. Method A pilot RCT was conducted at a teaching hospital. Intervention was based on the four-item Morisky Medication Adherence Scale (MMAS-4). The primary outcome measure was medication adherence assessed using the eight-item MMAS at baseline, at 1 month post hospital discharge and re-assessed 1 year after hospital discharge. Other outcomes included readmission and mortality rates. Results 61 patients were randomized to intervention (n = 30) and control (n = 31) groups. The mean age of the patients was 61 years (SD 12.73), 52.5% were males, and 57.4% were married or living with a partner. Mean number of prescribed medications per patient was 4.5 (SD 3.3). Medication adherence was correlated to intervention (p = 0.04) and after 1 month, 48.4% of patients in the control group and 83.3% in the intervention group were considered adherent. However, this difference decreased after 1 year, when adherence was 34.8% and 60.9%, respectively. Readmission and mortality rates were related to low adherence in both groups. Conclusion The intervention based on a validated patient self-report instrument for assessing adherence is a potentially effective method to improve adherent behavior and can be successfully used as a tool to guide adherence counseling in the clinical visit. However, a larger study is required to assess the real impact of intervention on these outcomes. PMID:25590930

Simple nudges such as reminders and feedback reports to either a patient or a partner may facilitate improved medication adherence. To test the impact of a pill bottle used to monitor adherence, deliver a daily alarm, and generate weekly medication adherence feedback reports on statin adherence. Three-month, three-arm randomized clinical trial (ClinicalTrials.gov identifier: NCT02480530). One hundred and twenty-six veterans with known coronary artery disease and poor adherence (medication possession ratio <80 %). Patients were randomized to one of three groups: (1) a control group (n = 36) that received a pill-monitoring device with no alarms or feedback; (2) an individual feedback group (n = 36) that received a daily alarm and a weekly medication adherence feedback report; and (3) a partner feedback group (n = 54) that received an alarm and a weekly feedback report that was shared with a friend, family member, or a peer. The intervention continued for 3 months, and participants were followed for an additional 3 months after the intervention period. Adherence as measured by pill bottle. Secondary outcomes included change in LDL (mg/dl), patient activation, and social support. During the 3-month intervention period, medication adherence was higher in both feedback arms than in the control arm (individual feedback group 89 %, partner feedback group 86 %, control group 67 %; p < 0.001 and = 0.001). At 6 months, there was no difference in medication adherence between either of the feedback groups and the control (individual feedback 60 %, partner feedback 52 %, control group 54 %; p = 0.75 and 0.97). Daily alarms combined with individual or partner feedback reports improved statin medication adherence. While neither an individual feedback nor partner feedback strategy created a sustainable medication adherence habit, the intervention itself is relatively easy to implement and low cost.

HIV-positive adolescents and young adults often experience suboptimal medication adherence, yet few interventions to improve adherence in this group have shown evidence of efficacy. We conducted a randomized trial of a two-way, personalized daily text messaging intervention to improve adherence to antiretroviral therapy (ART) among N = 105 poorly adherent HIV-positive adolescents and young adults, ages 16-29. Adherence to ART was assessed via self-reported visual analogue scale (VAS; 0-100 %) at 3 and 6-months for mean adherence level and proportion ≥90 % adherent. The average effect estimate over the 6-month intervention period was significant for ≥90 % adherence (OR = 2.12, 95 % CI 1.01-4.45, p < .05) and maintained at 12-months (6 months post-intervention). Satisfaction scores for the intervention were very high. These results suggest both feasibility and initial efficacy of this approach. Given study limitations, additional testing of this intervention as part of a larger clinical trial with objective and/or clinical outcome measures of adherence is warranted.

Food insecurity and malnutrition negatively affect adherence to antiretroviral therapy (ART) and are associated with poor HIV clinical outcomes. We examined the effect of providing household food assistance and nutrition education on ART adherence. A 12-month prospective clinical trial compared the effect of a monthly household food basket (FB) plus nutrition education (NE) versus NE alone on ART adherence on 400 HIV patients at four clinics in Honduras. Participants had been receiving ART for an average of 3.7 years and were selected because they had suboptimal adherence. Primary outcome measures were missed clinic appointments, delayed prescription refills, and self-reported missed doses of ART. These three adherence measures improved for both groups over 12 months (p < 0.01), mostly within 6 months. On-time prescription refills improved for the FB plus NE group by 19.6 % more than the group receiving NE alone after 6 months (p < 0.01), with no further change at 12 months. Change in missed appointments and self-reported missed ART doses did not significantly differ by intervention group.

Background: The aim of this study was to assess the impact of follow-up in renal protection clinics on the prescription of and adherence to cardioprotective drugs in patients with chronic kidney disease (CKD). Methods: We studied stage 4 and 5 CKD patients who initiated follow-up in three renal protection clinics. The prescription pattern of antihypertensive agents (AHA) and lipid-lowering agents (LLAs) was measured as the percentage of patients who are prescribed the agents of interest at a given time. Adherence to drug therapy was defined as the percentage of days, during a pre-defined observation period, in which patients have an on-hand supply of their prescribed medications. Results: A total of 259 CKD patients were enrolled and followed for up to 1 year after referral to renal protection clinics. There was a significant increase in the prescription of angiotensin-converting enzyme inhibitors (34-39%), angiotensin II receptor blockers (11-14%), beta-blockers (40-51%), calcium channel blockers (62-74%), diuretics (66-78%) and LLAs (39-47%) during follow-up in the renal protection clinic compared with baseline (P-values <0.01 for all comparisons). The proportions of patients with good (≥ 80%) and poor (< 80%) adherence to AHA (P = 0.41) and LLAs (P = 0.11) were similar in the year preceding and the year following the first visit to the renal protection clinics. Conclusion: Our results suggest that referral and follow-up in a renal protection clinic may increase the prescription of cardioprotective agents in CKD patients, but does not appear to improve adherence to these medications.

Background Non-adherence to prescribed medications is a serious health problem in the United States, costing an estimated $100 billion per year. While poor adherence should be addressable with point of care health information technology, integrating new solutions with existing electronic health records (EHR) systems require customization within each organization, which is difficult because of the monolithic software design of most EHR products. Objective The objective of this study was to create a published algorithm for predicting medication adherence problems easily accessible at the point of care through a Web application that runs on the Substitutable Medical Apps, Reusuable Technologies (SMART) platform. The SMART platform is an emerging framework that enables EHR systems to behave as “iPhone like platforms” by exhibiting an application programming interface for easy addition and deletion of third party apps. The app is presented as a point of care solution to monitoring medication adherence as well as a sufficiently general, modular application that may serve as an example and template for other SMART apps. Methods The widely used, open source Django framework was used together with the SMART platform to create the interoperable components of this app. Django uses Python as its core programming language. This allows statistical and mathematical modules to be created from a large array of Python numerical libraries and assembled together with the core app to create flexible and sophisticated EHR functionality. Algorithms that predict individual adherence are derived from a retrospective study of dispensed medication claims from a large private insurance plan. Patients’ prescription fill information is accessed through the SMART framework and the embedded algorithms compute adherence information, including predicted adherence one year after the first prescription fill. Open source graphing software is used to display patient medication information and the

Study on psychoeducation enhancing results of adherence in patients with schizophrenia (SPERA-S): study protocol for a randomized controlled trial

PubMed Central

2013-01-01

Background Poor adherence to pharmacotherapy negatively affects the course and the outcome of schizophreniaspectrum psychoses, enhancing the risk of relapse. Falloon and coworkers developed a Psychoeducation Program aimed at improving communication and problem-solving abilities in patients and their families. This study set out to evaluate changes in adherence to pharmacotherapy in patients diagnosed with schizophrenia-spectrum psychoses, by comparing one group exposed to the Falloon Psychoeducation Program (FPP) with another group exposed to family supportive therapy with generic information on the disorders. Methods 340 patients diagnosed with schizophrenia and related disorders according to standardized criteria from 10 participating units distributed throughout the Italian National Health System (NHS), will be enrolled with 1:1 allocation by the method of blocks of randomized permutations. Patients will be reassessed at 6, 12 and 18 months after start of treatment (duration: 6 months). The primary objective is to evaluate changes in adherence to pharmacotherapy after psychoeducation. Adherence will be assessed at three-month intervals by measuring blood levels of the primary prescribed drug using high pressure liquid chromatography, and via the Medication Adherence Questionnaire and a modified version of the Adherence Interview. Secondary objectives are changes in the frequency of relapse and readmission, as the main indicator of the course of the disorder. Enrolled patients will be allocated to the FPP (yes/no) randomly, 1:1, in a procedure controlled by the coordinating unit; codes will be masked until the conclusion of the protocol (or the occurrence of a severe negative event). The raters will be blind to treatment allocation and will be tested for blinding after treatment completion. Intention-to-treat will be applied in considering the primary and secondary outcomes. Multiple imputations will be applied to integrate the missing data. The study started

One of the most effective surgeries for sustainable weight loss in morbidly obese patients is laparoscopic sleeve gastrectomy (LSG). The present study aimed to assess the adherence of LSG patients with respect to following post-operative dietary requirements and micronutrient supplementation, as well as to investigate their perceived barriers in achieving optimal adherence. Retrospective data analysis was performed (3, 6, 9 and 12 months after LSG) using the medical records of 96 morbidly obese patients who had undergone LSG at our institution during 2011-2013. Data collected from patient records were: adherence to prescribed diet; adherence to prescribed consumption of fruit, vegetables, legumes and cereals; use of prescribed micronutrient supplements; and barriers to diet and micronutrient therapy adherence. Data were analysed using spss, version 14.0 (SPSS Inc., Chicago, IL, USA). At 3, 6, 9 and 12 months post-LSG, the rates of patient non-adherence to a prescribed diet were 39%, 45%, 51% and 74%, respectively. In particular, there was a low consumption of fruit, vegetables, legumes and cereals compared to the post-surgery prescription. In addition, the rates of patient non-adherence to prescribed micronutrient supplements at 3, 6, 9 and 12 months post-LSG were 43%, 51%, 59% and 67%, respectively. The main reasons for patient non-adherence to diet were poor self-discipline (72%) and poor family support (11%) whereas difficulty swallowing pills or capsules (61%) and cost (20%) were reported as the main barriers to post-LSG adherence. Morbidly obese patients who have undergone LSG do not follow exactly the post-operative dietary guidelines, including micronutrient therapy. © 2016 The British Dietetic Association Ltd.

Ongoing Health Education is a strategy for transformation of health practices, though the adherence of professionals is one of the challenges facing its implementation. Thus, the objective of this study was to investigate the factors associated with adherence of family doctors to the Ongoing Education Program in a southeastern Brazilian state from the perception of supervisors. It is a cross-sectional and quantitative study with the use of online questionnaires. Data were analyzed using the chi-square test with ongoing correction to determine the association between structure, topics, activities and difficulties of the supervisors working in Ongoing Health Education, difficulties of the physicians in Primary Health Care (PHC) and poor and good adherence to the program. Excellent medical participation was statistically related to the adequacy of physical space (p = 0.001), a multidisciplinary approach (p = 0.035) and epidemiological aspects (p = 0.043). Low adherence was associated with the inadequacy of the physical structure, difficulty understanding the methodology, less time in a supervisory position, multiple workdays, among others. A good adherence to Ongoing Health Education is a possibility for collective reconstruction of the everyday work of physicians in Primary Health Care.

Aims While suboptimal adherence to statin medication has been quantified in real-world patient settings, a better understanding of its impact is needed, particularly with respect to distinct problems of medication taking. Our aim was to synthesize current evidence on the impacts of statin adherence, discontinuation and persistence on cardiovascular disease and mortality outcomes. Methods We conducted a systematic review of peer-reviewed studies using a mapped search of Medline, Embase and International Pharmaceutical Abstracts databases. Observational studies that met the following criteria were included: defined patient population; statin adherence exposure; defined study outcome [i.e. cardiovascular disease (CVD), mortality]; and reporting of statin-specific results. Results Overall, 28 studies were included, with 19 studies evaluating outcomes associated with statin adherence, six with statin discontinuation and three with statin persistence. Among adherence studies, the proportion of days covered was the most widely used measure, with the majority of studies reporting increased risk of CVD (statistically significant risk estimates ranging from 1.22 to 5.26) and mortality (statistically significant risk estimates ranging from 1.25 to 2.54) among non-adherent individuals. There was greater methodological variability in discontinuation and persistence studies. However, findings of increased CVD (statistically significant risk estimates ranging from 1.22 to 1.67) and mortality (statistically significant risk estimates ranging from 1.79 to 5.00) among nonpersistent individuals were also consistently reported. Conclusions Observational studies consistently report an increased risk of adverse outcomes associated with poor statin adherence. These findings have important implications for patients and physicians and emphasize the importance of monitoring and encouraging adherence to statin therapy. PMID:25364801

The Influence of Chronic Ego Depletion on Goal Adherence: An Experience Sampling Study

2015-01-01

Although ego depletion effects have been widely observed in experiments in which participants perform consecutive self-control tasks, the process of ego depletion remains poorly understood. Using the strength model of self-control, we hypothesized that chronic ego depletion adversely affects goal adherence and that mental effort and motivation are involved in the process of ego depletion. In this study, 203 students reported their daily performance, mental effort, and motivation with respect to goal directed behavior across a 3-week time period. People with high levels of chronic ego depletion were less successful in goal adherence than those with less chronic ego depletion. Although daily effort devoted to goal adherence increased with chronic ego depletion, motivation to adhere to goals was not affected. Participants with high levels of chronic ego depletion showed a stronger positive association between mental effort and performance, but chronic ego depletion did not play a regulatory role in the effect of motivation on performance. Chronic ego depletion increased the likelihood of behavior regulation failure, suggesting that it is difficult for people in an ego-depletion state to adhere to goals. We integrate our results with the findings of previous studies and discuss possible theoretical implications. PMID:26562839

Is patient empowerment the key to promote adherence? A systematic review of the relationship between self-efficacy, health locus of control and medication adherence

PubMed Central

2017-01-01

Background Current health policies emphasize the need for an equitable doctor-patient relationship, and this requires a certain level of patient empowerment. However, a systematic review of the empirical evidence on how empowerment affects medication adherence—the extent to which patients follow the physician’s prescription of medication intake—is still missing. The goal of this systematic review is to sum up current state-of-the-art knowledge concerning the relationship between patient empowerment and medication adherence across medical conditions. As our conceptualization defines health locus of control and self-efficacy as being crucial components of empowerment, we explored the relationship between these two constructs and medication adherence. Methods Relevant studies were retrieved through a comprehensive search of Medline and PsychINFO databases (1967 to 2017). In total, 4903 publications were identified. After applying inclusion and exclusion criteria and quality assessment, 154 articles were deemed relevant. Peer-reviewed articles, written in English, addressing the relationship between empowerment (predictor) and medication adherence (outcome) were included. Findings High levels of self-efficacy and Internal Health Locus of Control are consistently found to promote medication adherence. External control dimensions were found to have mainly negative (Chance and God attributed control beliefs) or ambiguous (Powerful others attributed control beliefs) links to adherence, except for Doctor Health Locus of Control which had a positive association with medication adherence. To fully capture how health locus of control dimensions influence medication adherence, the interaction between the sub-dimensions and the attitudinal symmetry between the doctor and patient, regarding the patient’s control over the disease management, can provide promising new alternatives. Discussion The beneficial effect of patients’ high internal and concurrent physician

We evaluated the impact of antecedent specificity in goal statements on adherence to positive behavior-management strategies. Teaching staff were recruited from 2 different school settings where there were routine expectations to use behavior-specific praise in the classroom, but adherence was poor. In a concurrent multiple baseline design, the use of behavior-specific praise by 4 participants was found to be unaffected by goal statements that increasingly specified the behavior to be used and the conditions under which the behavior should occur. However, adherence by 3 of the 4 participants did change when goal statements included teacher-specified frequencies with which the behavior should occur. Results were systematically replicated in a second study in which, in a concurrent multiple baseline design, 3 participants showed marked increases in adherence when goal statements specified the target behavior, the conditions under which it should occur, and the frequency with which it should occur. © 2016 Society for the Experimental Analysis of Behavior.

Depression is associated with poor antiretroviral therapy (ART) adherence among people living with HIV/AIDS. This relationship may be moderated by an individual's social network characteristics. Our study sought to examine social network correlates of treatment adherence among HIV-positive men recruited from social service agencies throughout Los Angeles County (N = 150) to inform technology-driven social support interventions for this population. We administered egocentric social network and computer-assisted survey interviews focused on demographic characteristics, health history, depressive symptoms, and ART adherence, where adherence was assessed by the number of reasons participants missed taking their medication, if ever. Significant univariate correlates of adherence were included in a multivariable regression analysis, where the moderating effect of having a network member who reminds participants to take their HIV medication on the relationship between depression and adherence was tested. Over 60% of participants reported clinically significant depressive symptoms; this was significantly associated with lower adherence among those without someone in their social network to remind them about taking their HIV medication, even after adjusting for covariates in an ordinary least squares regression (adjusted mean difference b = -1.61, SE = 0.42, p = 0.0003). Having a network member who reminds participants to take their ART medication significantly ameliorated the negative association between depression and treatment adherence, especially for those reporting greater depressive symptoms (p = 0.0394). Additionally, participants demonstrated high rates of technology use to communicate with social network members. In order to achieve the aims of the National HIV/AIDS Strategy, innovative interventions addressing mental health to improve ART adherence are needed. Network strategies that leverage technology may be helpful for improving ART

Background Treatment adherence is often an important issue in the management of hypertension. Deep understanding of adherence behavior as well as its influential factors can expand knowledge about treatment adherence among hypertensives. Objective The aim of this study was to explore patients, their families, and healthcare providers’ experiences about hypertension treatment adherence in southeast of Iran. Design A qualitative study was conducted to explore the experience of patients, family members, and healthcare providers (n=18) by using a conventional content analysis. The purposive sampling method was used. Data were collected through semi-structured and deep interviews. Results Data analysis showed that hypertensive treatment adherence in an Iranian context is like an iceberg with two subthemes. The first subtheme relates to the upper and clear part of this iceberg and it consists of two categories, including 1) healthy and 2) unhealthy regimens. The second subtheme associates with under-water and unanticipated part and it consists of four categories, including 1) the nature of disease and treatment, 2) the individual resources, 3) the healthcare organization, and 4) the socio-cultural environment. Conclusions The treatment adherence features emerged in this study can be useful in designing and developing context-based hypertension interventions. Further qualitative and quantitative studies with a closer collaboration between the social, natural, and medical sciences in other Iranian populations are needed to confirm the findings.

Background The number of adolescents with chronic health conditions (CHCs) continues to increase. Medication nonadherence is a global challenge among adolescents across chronic conditions and is associated with poor health outcomes. While there has been growing interest in the use of mHealth technology to improve medication adherence among adolescents with CHCs, particularly text messaging and mobile phone apps, there has been no prior systematic review of their efficacy. Objective The purpose of this review was to systematically evaluate the most recent evidence for the efficacy of text messaging and mobile phone apps as interventions to promote medication adherence among adolescents with CHCs. Methods PubMed, Embase, CENTRAL, PsycINFO, Web of Science, Google Scholar, and additional databases were searched from 1995 until November 2015. An additional hand search of related themes in the Journal of Medical Internet Research was also conducted. The Preferred Reporting Results of Systematic Reviews and Meta-Analyses guidelines were followed. Two reviewers independently screened titles/abstracts, assessed full-text articles, extracted data from included articles, and assessed their quality using Grades of Recommendation, Assessment, Development, and Evaluation criteria. Included studies were described in original research articles that targeted adherence in adolescents with CHCs (12-24 years-old). Results Of the 1423 records examined, 15 met predefined criteria: text messaging (n=12) and mobile phone apps (n=3). Most studies were performed in the United States (11/15, 73%), were randomized-controlled trials (8/15, 53%), had a sample size <50 (11/15, 73%), and included adherence self-report and/or biomarkers (9/15, 60%). Only four studies were designed based on a theoretical framework. Approaches for text messaging and mobile phone app interventions varied across studies. Seven articles (7/15, 47%) reported significant improvement in adherence with moderate to large

BACKGROUND African-American and low-income women have lower rates of cancer screening and higher rates of late-stage disease than do their counterparts. OBJECTIVE To examine the effects of primary care, health insurance, and HMO participation on adherence to regular breast, cervical, and colorectal cancer screening. DESIGN Random-digit-dial and targeted household telephone survey of a population-based sample. SETTING Washington, D.C. census tracts with ≥30% of households below 200% of federal poverty threshold. PARTICIPANTS Included in the survey were 1,205 women over age 40, 82% of whom were African American. MAIN OUTCOME MEASURES Adherence was defined as reported receipt of the last 2 screening tests within recommended intervals for age. RESULTS The survey completion rate was 85%. Overall, 75% of respondents were adherent to regular Pap smears, 66% to clinical breast exams, 65% to mammography, and 29% to fecal occult blood test recommendations. Continuity with a single primary care practitioner, comprehensive service delivery, and higher patient satisfaction with the relationships with primary care practitioners were associated with higher adherence across the 4 screening tests, after considering other factors. Coordination of care also was associated with screening adherence for women age 65 and over, but not for the younger women. Compared with counterparts in non-HMO plans, women enrolled in health maintenance organizations were also more likely to be adherent to regular screening (e.g., Pap, odds ratio [OR] 1.89, 95% confidence interval [CI] 1.11 to 3.17; clinical breast exam, OR 2.04, 95% CI 1.21 to 3.44; mammogram, OR 1.95, 95% CI 1.15 to 3.31; fecal occult blood test, OR 1.70, 95% CI 1.01 to 2.83.) CONCLUSIONS Organizing healthcare services to promote continuity with a specific primary care clinician, a comprehensive array of services available at the primary care delivery site, coordination among providers, and better patient-practitioner relationships

Low therapeutic adherence to medication is very common. Clinical effectiveness is related to dose rate and route of administration and so poor therapeutic adherence can reduce the clinical benefit of treatment. The therapeutic adherence of patients with chronic obstructive pulmonary disease (COPD) is extremely poor according to most studies. The research about COPD adherence has mainly focussed on quantifying its effect, and few studies have researched factors that affect non-adherence. Our study will evaluate the effectiveness of a multifactor intervention to improve the therapeutic adherence of COPD patients. A randomized controlled clinical trial with 140 COPD diagnosed patients selected by a non-probabilistic method of sampling. Subjects will be randomly allocated into two groups, using the block randomization technique. Every patient in each group will be visited four times during the year of the study. Motivational aspects related to adherence (beliefs and behaviour): group and individual interviews; cognitive aspects: information about illness; skills: inhaled technique training. Reinforcement of the cognitive-emotional aspects and inhaled technique training will be carried out in all visits of the intervention group. Adherence to a prescribed treatment involves a behavioural change. Cognitive, emotional and motivational aspects influence this change and so we consider the best intervention procedure to improve adherence would be a cognitive and emotional strategy which could be applied in daily clinical practice. Our hypothesis is that the application of a multifactor intervention (COPD information, dose reminders and reinforcing audiovisual material, motivational aspects and inhalation technique training) to COPD patients taking inhaled treatment will give a 25% increase in the number of patients showing therapeutic adherence in this group compared to the control group.We will evaluate the effectiveness of this multifactor intervention on patient adherence

To identify the predictors of adherence in patients with coronary heart disease after a percutaneous coronary intervention. Adherence is a key factor in preventing the progression of coronary heart disease. An analytical multihospital survey study. A survey of 416 postpercutaneous coronary intervention patients was conducted in 2013, using the Adherence of People with Chronic Disease Instrument. The instrument consists of 37 items measuring adherence and 18 items comprising sociodemographic, health behavioural and disease-specific factors. Adherence consisted of two mean sum variables: adherence to medication and a healthy lifestyle. Based on earlier studies, nine mean sum variables known to explain adherence were responsibility, cooperation, support from next of kin, sense of normality, motivation, results of care, support from nurses and physicians, and fear of complications. Frequencies and percentages were used to describe the data, cross-tabulation to find statistically significant background variables and multivariate logistic regression to confirm standardised predictors of adherence. Patients reported good adherence. However, there was inconsistency between adherence to a healthy lifestyle and health behaviours. Gender, close personal relationship, length of education, physical activity, vegetable and alcohol consumption, LDL cholesterol and duration of coronary heart disease without previous percutaneous coronary intervention were predictors of adherence. The predictive factors known to explain adherence to treatment were male gender, close personal relationship, longer education, lower LDL cholesterol and longer duration of coronary heart disease without previous percutaneous coronary intervention. Because a healthy lifestyle predicted factors known to explain adherence, these issues should be emphasised particularly for female patients not in a close personal relationship, with low education and a shorter coronary heart disease duration with previous

To quantify the impact of non-adherence on the clinical effectiveness of antibiotics for acute exacerbations of chronic bronchitis (AECB) and to estimate the economic consequences for Spain, Italy and the United States. Standard systematic reviewing procedures were followed to identify randomised controlled clinical trials of antibiotic treatment for acute respiratory tract infection for which adherence was reported. A decision-analytic model was then constructed to evaluate the impact of non-adherence to antibiotic treatment on clinical effectiveness and costs per AECB episode. The model compared the total treatment costs, cure rates and incremental costs per cure for a poor compliance group (PCG) against a good compliance group (GCG). Clinical and resource use estimates were from the published literature and physician surveys. Twenty-five articles met the criteria of the systematic review, although only one reported treatment success by adherence status. The relative risk of clinical effectiveness if non-adherent was 0.75 (95%CI 0.73-0.78). Based on this single study, the model predicted that 16-29% more patients would be cured in the GCG vs. the PCG, and payers would save up to euro122, euro179 and US$141 per AECB episode in Spain, Italy and the United States, respectively. Non-adherence to antibiotics for AECB may have an impact on clinical effectiveness, which is associated with increased costs.

Poor adherence and a lack of understanding of medication instructions for oral antidiabetic use are key factors that inhibit the control of glycemic levels. The aforementioned situation needs intervention to improve medication adherence and the therapy. This study was conducted with a quasi-experimental design with prospective data collection. The subjects of this study were 50 outpatients with type 2 diabetes melitus (T2DM) who had received oral antidiabetic medicine therapy at least six months prior to adherence measurement. The patients were classified into two groups—the control group and the intervention group. The intervention group received Short Message Service (SMS) messages of diabetes education, while the control group did not. Data collection was conducted by doing interviews and administering the Morisky Medication Adherence Scale (MMAS) questionnaire. The results showed the increase in adherence in the intervention group as 1.15 ± 1.04 and that in the control group as 0.72 ± 0.90. These results indicated that there were significant differences in MMAS score between the control and intervention groups (p < 0.05). The decrease in fasting blood glucose and glucose measured 2 h postprandially was greater in the intervention group than that in the control group. It was concluded that the provision of education through SMS had a positive effect on medication adherence and glycemic levels. PMID:28545222

This study investigated the household economic burden of eating disorders and cost-related non-adherence to treatment in Australia. Multi-centre prospective observational study using a structured questionnaire. Ninety participants were recruited from two clinic settings in New South Wales, Australia and from the community using social media. The primary outcome measures were household economic burden of illness measured in terms of out-of-pocket expenditure, household economic hardship and cost-related non-adherence. The pattern of out-of-pocket expenditure varied by diagnosis, with Bulimia Nervosa associated with the highest total mean expenditure (per three months). Economic hardship was reported in 96.7% of participants and 17.8% reported cost-related non-adherence. Those most likely to report cost-related non-adherence had a longer time since diagnosis. Cost-related non-adherence and higher out-of-pocket expenditure were associated with poorer quality of life, a more threatening perception of the impact of the illness and poor self-reported health. This study is the first to empirically and quantitatively examine the household economic burden of eating disorders from the patient perspective. Results indicate that households experience a substantial burden associated with the treatment and management of an eating disorder. This burden may contribute to maintaining the illness for those who experience cost-related non-adherence and by negatively influencing health outcomes. Current initiatives to implement sustainable and integrated models of care for eating disorders should strive to minimise the economic impact of treatment on families.

The medication management of patients following coronary artery bypass graft (CABG) surgery may include antiplatelet agents, beta-blockers, angiotensin-converting enzyme inhibitors, and statins. However, poor adherence is common, and patient attitudes and beliefs play a role in adherence. To evaluate the association between self-reported adherence and the beliefs patients have about cardiovascular medicines used after CABG. Adults were surveyed 6-24 months following CABG. The validated Beliefs about Medicines Questionnaire (BMQ) assessed attitudes concerning the Specific Necessity, Specific Concerns, General Harm, and General Overuse of medicines. The validated medication adherence scale assessed self-reported adherence. Analysis included univariate comparison (BMQ scales) and multivariate logistic regression (identification of adherence predictor variables). Of 387 patients surveyed, 132 (34%) completed the questionnaire. Nonparticipants were more likely to be female and have undergone 1- or 2-vessel CABG procedures compared with 3- or 4-vessel procedures. Subjects were primarily English-speaking, white, and male. Adherent behavior was reported in 73 of 132 patients (55%). The average period between CABG and the survey was 16 months. Nonadherent patients were in stronger agreement on the General Overuse (p = 0.01) and General Harm (p = 0.04) scales. The adjusted odds of adherent behavior were significantly lower, with an increasing General Overuse score (OR 0.83; 95% CI 0.72 to 0.95; p = 0.007); an annual income of $50,000 to $100,000 relative to less than $20,000 (OR 0.36; 95% CI 0.14 to 0.91; p = 0.031), and a living status of "alone" compared with "with adults and no children" (OR 0.20; 95% CI 0.06 to 0.65; p = 0.007). The odds ratio of self-reported adherence was higher with increasing age (OR 1.05; 95% CI 1.01 to 1.09; p = 0.023). In summary, patient beliefs and attitudes regarding medications, along with other social, economic, and demographic factors, help

The purpose of the current study was to examine perceived exposure to systemic racism as a moderator of the effects of perceived exposure to provider racial biases on treatment adherence and mistrust of health care for a sample of African American hypertensive patients. We hypothesized that patients who endorsed high levels of systemic racism would exhibit poor adherence to hypertension treatment and increased mistrust in health care in relation to perceptions of exposure to provider racial biases. The sample consisted of 100 African American patients who ranged in age from 24 to 82 years. All were diagnosed with hypertension and were recruited from an outpatient clinic located in the Southeastern region of the United States. Moderated regression analyses were performed to test the study hypotheses. Findings revealed a positive, significant main effect for perceived provider racial biases in predicting mistrust of care. This finding suggested that an increase in mistrust of health care was associated with increased perceptions of provider biases. In predicting treatment adherence, a significant interaction revealed that patients who endorsed low and moderate degrees of exposure to systemic racism displayed poor adherence to treatment in relation to greater perceptions of provider racial biases. The overall findings suggest that patients who perceive themselves as infrequently exposed to systemic racism possess the greatest risk for nonadherence to hypertension treatment in relation to increased perceptions of provider racial biases. Implications of the findings are discussed. 2014 APA, all rights reserved

The aim of this study was to categorize the facilitators and barriers of exercise and identify methods to promote exercise adherence in the osteoporosis population. Despite the fair methodological quality of included randomized controlled trials (RCTs), less than 75 % identified facilitators and barriers to exercise. Methods to promote and measure exercise adherence were poorly reported. Several studies have shown exercise to be successful in maintaining or increasing BMD in individuals with low bone mass. Yet, adherence to exercise is poor, with 50 % of those registered in an exercise program dropping out within the first 6 months, lack of time being the number one barrier in many populations. However, in the osteoporosis population, the main facilitator and barrier to exercise is still unclear. The aim of this study is to examine the extent to which RCTs reported the facilitators and the barriers to exercise and identified methods to promote adherence to an exercise program. PubMed, CINHAL, EMBASE, and the Cochrane Review were queried using a predefined search criterion, and the resulting citations were imported into DistillerSR. Screening was carried out by two independent reviewers, and articles were included in the analysis by consensus. The methodological quality of included studies was assessed using the PEDro scale. Fifty-four RCTs examining exercise interventions in patients with osteopenia or osteoporosis were included. A spectrum of facilitators and barriers to exercise for osteoporotic patients were identified; however, no one facilitator was more frequently reported than the other. The most commonly reported barriers were lack of time and transportation. In most RCTs, methods to promote and measure exercise adherence were unsatisfactory. Of the 54 papers, 72 % reported an adherence rate to an exercise program; the lowest reported rate was 51.7 %, and the highest 100 %. Most RCTs found were of fair quality; however, less than three quarters

Background: The prevalence of depression in celiac disease (CD) is high, and patients are often burdened socially and financially by a gluten-free diet. However, the relationship between depression, somatic symptoms and dietary adherence in CD is complex and poorly understood. We used a patient powered research network (iCureCeliac®) to explore the effect that depression has on patients’ symptomatic response to a gluten-free diet (GFD). Methods: We identified patients with biopsy-diagnosed celiac disease who answered questions pertaining to symptoms (Celiac Symptom Index (CSI)), GFD adherence (Celiac Dietary Adherence Test (CDAT)), and a 5-point, scaled question regarding depressive symptoms relating to patients’ celiac disease. We then measured the correlation between symptoms and adherence (CSI vs. CDAT) in patients with depression versus those without depression. We also tested for interaction of depression with regard to the association with symptoms using a multiple linear regression model. Results: Among 519 patients, 86% were female and the mean age was 40.9 years. 46% of patients indicated that they felt “somewhat,” “quite a bit,” or “very much” depressed because of their disorder. There was a moderate correlation between worsened celiac symptoms and poorer GFD adherence (r = 0.6, p < 0.0001). In those with a positive depression screen, there was a moderate correlation between worsening symptoms and worsening dietary adherence (r = 0.5, p < 0.0001) whereas in those without depression, the correlation was stronger (r = 0.64, p < 0.0001). We performed a linear regression analysis, which suggests that the relationship between CSI and CDAT is modified by depression. Conclusions: In patients with depressive symptoms related to their disorder, correlation between adherence and symptoms was weaker than those without depressive symptoms. This finding was confirmed with a linear regression analysis, showing that depressive symptoms may modify the

Cardiovascular diseases are the leading causes of mortality and morbidity in Western countries. The possible synergistic effect of poor adherence to a Mediterranean diet (MD) and other risk factors for acute myocardial infarction (AMI) such as hypertension, cholesterol, ever smoker, BMI> 25, diabetes, has not been deeply studied. Case-control study. Patients with first AMI and controls from four tertiary referral Italian centers were screened for enrolment. Dietary information was collected through a questionnaire and a MD adherence score was calculated. Physical activity and smoking habits were also registered. The Synergy Index was calculated according to Rothman. 127 cases and 173 controls were enrolled. The analysis was conducted using a dichotomous variable for the MD score with values ≥7 representing good adherence. Multivariate analysis showed the following variables associated to AMI: ever smoker (OR = 2.08), diabetes (OR = 1.42), hypertension (OR = 2.08), hypercholesterolemia (OR = 2.47), BMI> 25 (OR = 1.99), while a protective effect emerged both in subjects scoring > 7 on the MD score (OR = 0.55) and in subjects resident of Southern Italy (OR = 0.38). A synergistic effect does exist between poor adherence to the MD and the following risk factors: hypertension, hypercholesterolemia, BMI >25, diabetes and being a resident in central and northern Italy. Synergy between heart disease risk factors and MD underlines the need to enlarge the list of known modifiable cardiovascular risk factors to include and promote adherence to Mediterranean dietary habits.

Poor medication adherence is associated with adverse health outcomes and higher costs of care. However, inconsistencies in the assessment of adherence are found in the literature. To evaluate the effect of different measures of adherence in the comparative effectiveness of complex interventions to enhance patients' adherence to prescribed medications. A systematic review with network meta-analysis was performed. Electronic searches for relevant pairwise meta-analysis including trials of interventions that aimed to improve medication adherence were performed in PubMed. Data extraction was conducted with eligible trials evaluating short-period adherence follow-up (until 3 months) using any measure of adherence: self-report, pill count, or MEMS (medication event monitoring system). To standardize the results obtained with these different measures, an overall composite measure and an objective composite measure were also calculated. Network meta-analyses for each measure of adherence were built. Rank order and surface under the cumulative ranking curve analyses (SUCRA) were performed. Ninety-one trials were included in the network meta-analyses. The five network meta-analyses demonstrated robustness and reliability. Results obtained for all measures of adherence were similar across them and to both composite measures. For both composite measures, interventions comprising economic + technical components were the best option (90% of probability in SUCRA analysis) with statistical superiority against almost all other interventions and against standard care (odds ratio with 95% credibility interval ranging from 0.09 to 0.25 [0.02, 0.98]). The use of network meta-analysis was reliable to compare different measures of adherence of complex interventions in short-periods follow-up. Analyses with longer follow-up periods are needed to confirm these results. Different measures of adherence produced similar results. The use of composite measures revealed reliable alternatives

2017-07-01

Background: This study examined the extent to which cancer programs demonstrated adherence to their own prescribed screening protocol, and whether adherence to that protocol was associated with medical service utilization. The hypothesis is that higher rates of service utilization are associated with lower rates of adherence to screening protocols. Methods: Oncology social workers at Commission on Cancer-accredited cancer programs reviewed electronic health records (EHRs) in their respective cancer programs during a 2-month period in 2014. Rates of overall adherence to a prescribed distress screening protocol were calculated based on documentation in the EHR that screening adherence and an appropriate clinical response had occurred. We examined documentation of emergency department (ED) use and hospitalization within 2 months after the screening visit. Results: Review of 8,409 EHRs across 55 cancer centers indicated that the overall adherence rate to screening protocols was 62.7%. The highest rates of adherence were observed in Community Cancer Programs (76.3%) and the lowest rates were in NCI-designated Cancer Centers (43.3%). Rates of medical service utilization were significantly higher than expected when overall protocol adherence was lacking. After controlling for patient and institutional characteristics, risk ratios for ED use (0.82) and hospitalization (0.81) suggest that when overall protocol adherence was documented, 18% to 19% fewer patients used these medical services. Conclusions: The observed associations between a mandated psychosocial care protocol and medical service utilization suggest opportunities for operational efficiencies and costs savings. Further investigations of protocol integrity, as well as the clinical care models by which psychosocial care is delivered, are warranted.

Background Continuous positive airway pressure (CPAP) therapy is an efficacious treatment for patients diagnosed with obstructive sleep apnea (OSA). However, there are only few data on long-term adherence. The aim of this study is to quantify the extent of non-adherence and describe the clinical characteristics. Methods A retrospective study including 695 patients with newly diagnosed OSA and prescribed CPAP therapy within an inclusion period of 14 months. All patients were offered free of charge individually adjusted CPAP therapy. Data on comorbidity, medication, BMI and Epworth Sleepiness Score (ESS) were obtained by questionnaires and consultation with an otorhinolaryngeal specialist. Results The median follow-up time after initiating CPAP therapy was 3.0 (range 2.4–3.6) years. An adherence rate of 89% was found for severe OSA, 71% for moderate OSA and 55% for mild OSA. 18% initiated humidification. Patients adherent to CPAP had a significantly higher Body Mass Index (BMI), Apnea Hypopnea Index (AHI), Oxygen Desaturation Index (ODI) and ESS compared to non-adherent patients. Furthermore, adherence was associated with a higher frequency of observed interrupted breathing, a less frequent use of hypnotic drugs, fewer smokers, and they were more often offered humidification. Age, gender and comorbidity were not significantly associated with adherence. In a Cox model only AHI (Hazard Ratio (HR) 0.963, p < 0.001), ESS (HR 0.939, p = 0.001) and smoking (HR 1.576, p = 0.022) were independently associated with CPAP non-adherence. Conclusions The severity of OSA, subjective daytime sleepiness and smoking status are independently related to adherence to CPAP therapy. PMID:29253872

Background Many asthma-related exacerbations could be prevented by consistent use of daily inhaled corticosteroid therapy (ICS-Rx). Objectives We sought to measure the potential cost savings that could accrue from increasing ICS-Rx adherence in children. Study Design We measured observed costs for a cohort of 43,156 Medicaid-enrolled children in 14 southern states whose initial ICS-Rx was prescribed in 2007. Methods Adherence rates and associated costs were calculated from Medicaid claims. Children were categorized as high or low adherence based on the ratio of ICS-Rx claims filled to total asthma drug claims. Branching tree simulation was used to project the potential cost savings achieved by increasing the proportion of children with ICS-Rx to total asthma Rx ratios greater than 0.5 to 20%, 40%, 60%, 80%, and 100%. Results Increasing the proportion of children who maintain higher adherence after initial ICS-Rx to 40% would generate savings of $95 per child per year. An intervention costing $10 per member per month that resulted in even half of the children maintaining high adherence would generate a 98% return on investment for managed care plans or state Medicaid programs. Net costs decreased incrementally at each level of increase in ICS-Rx adherence. The projected Medicaid cost savings for these 14 states in 2007 ranged from $8.2 million if 40% of the children achieved high adherence, to $57.5 million if 80% achieved high adherence. Conclusions If effective large-scale interventions can be found, there are substantial cost savings to be gained from even modest increases in real-world adherence to ICS-Rx among Medicaid-enrolled children with asthma.

Context: The dental setting represents an unrealized opportunity to increase adherence to preventive services and improve health outcomes. Objective: To compare adherence to a subset of Healthcare Effectiveness Data and Information Set (HEDIS) measures among a population that received dental care with a population that did not receive dental care. Design: Using a retrospective cohort design, we identified 5216 adults who received regular dental care and 5216 persons who did not. The groups were matched on propensity scores, were followed for 3 years, and retained medical and dental benefits. Receipt of dental care was defined as 1 or more dental visits in each 12-month period. Main Outcome Measures: Outcome measures were assessed in a subpopulation that qualified for 1 of 5 HEDIS denominator groups (dental = 4184 patients; nondental = 3871 patients). They included 3 preventive measures (cervical, colorectal, and breast cancer screening), 4 chronic disease management services (hemoglobin A1c and low-density lipoprotein cholesterol testing, and nephropathy and retinopathy screening among the diabetes mellitus [DM] population), and 4 health outcome measures (poor glycemic control, low-density lipoprotein cholesterol control, blood pressure control in the DM population, and blood pressure control in the hypertensive population). Results: Dental care was associated with higher adherence to all three cancer screening measures, one of four disease management services (higher retinopathy screening), and three of four health outcomes (better glycemic control in the DM population and better blood pressure control in the DM and hypertensive populations). Conclusions: Dental care was associated with improved adherence to 7 of 11 HEDIS measures. PMID:26580145

Background The limited implementation of clinical pharmacy service programs and the lack of studies identifying barriers to achieve blood glucose control have all attributed to the increased proportion of type 2 diabetes patients who have poor glycemic control in Jordan. Objective To explore factors associated with higher HbA1c in patients with type 2 diabetes in Jordan. Method Variables including socio-demographics, disease and treatment factors were collected from171 patients with type2 diabetes at an outpatient diabetes clinic in Amman. Validated questionnaires were used to assess medication adherence, self-care activities, diabetes knowledge and health-related quality of life in addition to data collected from medical records. After the single-predictor analysis, stepwise linear regression was performed to develop a model with variables that best predicted hemoglobin A1c. Results Medication adherence was inversely associated with HbA1c values (β = -0.275; t = 2.666; P < 0.01), indicating better glycemic control. Receiving insulin therapy was also associated with less HbA1c values and better glycemic control (β = - 0.184; t = 2.080; P < 0.05). Patients who had one or more comorbid conditions (β = 0.215; t = 2.264; P < 0.05) and those with longer diabetes duration (β = 0.092; t = 1.339; P < 0.05) were found to have significantly higher HbA1c values. Conclusions Emphasizing medication adherence, particularly for patients with longer duration of diabetes and those with multiple comorbid diseases should be strongly considered in future diabetes management programs implemented to improve glycemic control in patients with type 2 diabetes.

Charach, Alice; Volpe, Tiziana; Boydell, Katherine M; Gearing, Robin E

2008-01-01

This article provides a theoretical review of treatment adherence for children and youth with psychiatric disorders where pharmacological agents are first-line interventions. Four empirically based models of health behavior are reviewed and applied to the sparse literature about medication adherence for children with attention-deficit/hyperactivity disorder and young people with first-episode psychosis. Three qualitative studies of medication use are summarized, and details from the first-person narratives are used to illustrate the theoretical models. These studies indicate, when taken together, that the clinical approach to addressing poor medication adherence in children and youth with psychiatric disorders should be guided by more than one theoretical model. Mental health experts should clarify beliefs, address misconceptions, and support exploration of alternative treatment options unless contraindicated. Recognizing the larger context of the family, allowing time for parents and children to change their attitudes, and offering opportunities for easy access to medication in the future are important ways of respecting patient preferences, while steering them toward best-evidence interventions. Future research using qualitative methods of inquiry to investigate parent, child, and youth experiences of mental health interventions should identify effective ways to improve treatment adherence.

Adherence to tuberculosis care in Canadian Aboriginal populations, Part 1: definition, measurement, responsibility, barriers.

PubMed

Orr, Pamela

2011-04-01

In a 2-part series, the current literature with respect to adherence to tuberculosis care among Canadian Aboriginal populations is reviewed. In the current paper, which comprises part 1 of this review, adherence is defined, and methods of measurement, issues of responsibility and potential barriers to adherence are explored. Study design. Literature review. A systematic search and analytic review of relevant studies was undertaken, including an online search of electronic databases (PubMed, PsychINFO, MEDLINE, Native Health Database, Scopus, Social Science Citation Index) and publications by governmental and non-governmental agencies. Poor adherence to therapy for TB disease is the most common cause of initial treatment failure and of disease relapse worldwide. Adherence to care for TB disease is necessary for the health of both the affected individual and society as a whole. Adherence is a task-specific behaviour that is not inherent to ethnic identity. The term applies only when common agreement over a care plan has been reached between patient and provider. The International Standards for Tuberculosis Care and the Patients Charter outline the responsibilities for adherence on the part of both patients and providers. For Canadian Aboriginals, barriers to adherence may derive from a complex interaction between the health system, personal factors and social factors, which may include dysfunctional acute and public health systems, dissonant (between health care provider and patient) belief systems, concurrent co-morbidities and life stressors, poverty and social stigma. Adherence is a task-specific behaviour, not a personality trait. It is influenced by the interaction of systemic, personal and societal factors. These factors must be understood within the historical experience of TB and the cultural meaning of health and illness among Indigenous Canadians.

The objective of the study was to assess the adherence to hormonal contraception (pill, patch, ring, or injectable) among women veterans and examine the relationships between race/ethnicity and the months of contraceptive supply dispensed with contraceptive adherence. We conducted a retrospective analysis of the Department of Veterans Affairs (VA) national databases to examine the adherence to hormonal contraception over 12 months among women aged 18-45 years who had hormonal contraceptive coverage during the first week of fiscal year 2008. We examined several adherence indicators including gaps between refills and months of contraceptive coverage. Descriptive statistics and multivariable models were used to examine the associations between race/ethnicity and contraceptive supply dispensed with adherence. Our cohort included 6946 women: 47% were white, 6% were Hispanic, 22% were black, and 25% were other race or had missing race information. Most women (83%) received a 3 month supply of contraception at each fill. More than 64% of women had at least 1 gap in coverage of 7 days or longer. Only 22% of women received a full 12 months of contraception without any gaps (perfect adherence). Compared with whites, Hispanics were significantly more likely to experience gaps (64% vs 70%; P = .02), and Hispanics and blacks received fewer months of contraceptive coverage (9.3 vs 8.9 and 9.0, P < .001). Compared with women receiving 3 month supplies, those receiving 1 month supplies had a higher likelihood of a gap (63% vs 72%, P < .001), fewer months of coverage (9.3 vs 6.9, P < .001), and a lower likelihood of perfect adherence (22% vs 11%, P < .001). Adherence to hormonal contraception among women veterans is poor. Efforts to improve contraceptive adherence and lower risk of unintended pregnancy are needed; dispensing more months of supply for hormonal contraception may be a promising strategy.

Schwalbe, Craig; Gearing, Robin

2012-01-01

Poor adherence of children and adolescents to evidence-based psychosocial interventions remains a fundamental impediment to treatment effectiveness. To maintain client adherence, researchers and clinicians have employed a number of adherence-promoting strategies, from telephone calls and letters to providing transportation costs and child care to motivational enhancement therapies. However, the influence of adherence promoters on intervention outcomes has not been reported. This study examined the moderating effect of adherence-promoting strategies in a survey and meta-analysis of randomized clinical trials of cognitive behavioral treatments, interpersonal therapy, and psycho-education for children and adolescents with mental health problems (k = 33). Results indicated the type and intensity of adherence promoters' moderated study effect sizes according to client characteristics (age, gender, diagnosis). Preliminary findings suggest that males had higher effect sizes when more intensive adherence-promoting efforts were employed. Adherence-promoting efforts were associated with lower effect sizes for youths who were diagnosed with externalizing disorders. Results of this study suggest directions for future research to clarify clinical guidelines to maximize retention in evidence-based psychotherapy. © 2012 American Orthopsychiatric Association.

[Treating coeliac disease. How do we measure adherence to the gluten-free diet?

PubMed

Aranda, Elisa A; Araya, Magdalena

Coeliac disease (CD) is a systemic autoimmune disorder triggered by gluten consumption in genetically susceptible individuals. It exhibits several clinical features, such as blood auto-antibodies (anti-endomysial antibodies EMA, anti-transglutaminase antibodies tTG, anti-deamidated gliadin peptides PGD), plus variable degrees of damage in the small intestinal mucosa. In Chile, tTG is positive in 0.76% in individuals >15 years, with the prevalence of CD being estimated at 0.6%. Approximately17% of first-degree relatives of coeliac patients have been reported tTG positive. To date, the gluten free diet (GFD) is the only known treatment for CD. To be effective, this must be lifelong, permanent, and strict. Gluten content in the GFD is not zero, but is limited to a cut-off of 3ppm (ormg/kg of product) in Chile. Mortality higher than that of the general population has been reported among coeliac patients, and poor adherence to GFD is associated with complications (mainly autoimmune processes and cancer). GFD is difficult to maintain strictly and poor adherence is by far the main cause of lack of response to treatment. Follow-up of adherence is also difficult because there are no objective measurements to assess it. In clinical practice determination of serum EMA, tTG and PGD is routinely used for these purposes, although more recently, the interview by an expert dietitian, validated questionnaires and measurement of faecal 33-mer peptide are being assessed as alternatives or complements to measure adherence to GFD. A review is presented with the current concepts on the available tools to follow up patients on GFD, emphasising those available in Chilel. Copyright © 2016 Sociedad Chilena de Pediatría.

Tuberculosis (TB) is a major contributor to the global burden of disease and has received considerable attention in recent years, particularly in low- and middle-income countries where it is closely associated with HIV/AIDS. Poor adherence to treatment is common despite various interventions aimed at improving treatment completion. Lack of a comprehensive and holistic understanding of barriers to and facilitators of, treatment adherence is currently a major obstacle to finding effective solutions. The aim of this systematic review of qualitative studies was to understand the factors considered important by patients, caregivers and health care providers in contributing to TB medication adherence. We searched 19 electronic databases (1966-February 2005) for qualitative studies on patients', caregivers', or health care providers' perceptions of adherence to preventive or curative TB treatment with the free text terms "Tuberculosis AND (adherence OR compliance OR concordance)". We supplemented our search with citation searches and by consulting experts. For included studies, study quality was assessed using a predetermined checklist and data were extracted independently onto a standard form. We then followed Noblit and Hare's method of meta-ethnography to synthesize the findings, using both reciprocal translation and line-of-argument synthesis. We screened 7,814 citations and selected 44 articles that met the prespecified inclusion criteria. The synthesis offers an overview of qualitative evidence derived from these multiple international studies. We identified eight major themes across the studies: organisation of treatment and care; interpretations of illness and wellness; the financial burden of treatment; knowledge, attitudes, and beliefs about treatment; law and immigration; personal characteristics and adherence behaviour; side effects; and family, community, and household support. Our interpretation of the themes across all studies produced a line

Nonadherence to antipsychotic medication among patients with schizophrenia results in poor symptom management and increased health care and other costs. Despite its health impact, medication adherence remains difficult to accurately assess. New technologies offer the possibility of real-time patient monitoring data on adherence, which may in turn improve clinical decision making. However, the economic benefit of accurate patient drug adherence information (PDAI) has yet to be evaluated. To quantify how more accurate PDAI can generate value to payers by improving health care provider decision making in the treatment of patients with schizophrenia. A 3-step decision tree modeling framework was used to measure the effect of PDAI on annual costs (2016 U.S. dollars) for patients with schizophrenia who initiated therapy with an atypical antipsychotic. The first step classified patients using 3 attributes: adherence to antipsychotic medication, medication tolerance, and response to therapy conditional on medication adherence. The prevalence of each characteristic was determined from claims database analysis and literature reviews. The second step modeled the effect of PDAI on provider treatment decisions based on health care providers' survey responses to schizophrenia case vignettes. In the survey, providers were randomized to vignettes with access to PDAI and with no access. In the third step, the economic implications of alternative provider decisions were identified from published peer-reviewed studies. The simulation model calculated the total economic value of PDAI as the difference between expected annual patient total cost corresponding to provider decisions made with or without PDAI. In claims data, 75.3% of patients with schizophrenia were found to be nonadherent to their antipsychotic medications. Review of the literature revealed that 7% of patients cannot tolerate medication, and 72.9% would respond to antipsychotic medication if adherent. Survey responses by

Poor adherence of patients with type 2 diabetes to treatment is one of the most complex and important clinical concerns. It is the main issue of the present decade and acknowledged as a challenge to control and treat diabetes. This study was carried out to explore and understand how adherence to treatment process occurs among Iranian patients with type 2 diabetes. The present study is qualitative with grounded theory approach. The data were collected from December 2015 to July 2016 in Tehran (Iran) through individual semi-structured in-depth interviews, field notes, and memos from 21 patients with type 2 diabetes; combined with two members of their families and a healthcare professional. The data were analyzed based on Corbin and Strauss constant comparative analysis (2008). Adherence to treatment is a transitional, interactive, and continuous process. For patients with diabetes, this process includes unperceived threat in diagnosis time (poor knowledge and skills, bottleneck of dependencies, superficial understanding of the new situation), bitter belief (downhill quality of life, physical and emotional treatment feedbacks), and adaptation to treatment (self-care dominance, regimen integration in daily activities). The process of adherence to treatment was influenced by knowledge and skill, social support, beliefs and values, psychological characteristics of people, and the nature of diabetes. Adherence to treatment in Iranian people with diabetes depends on the family and social context, which is challenging for the patient and leads to the negligence of health behaviors. It is vital for healthcare providers to identify these factors to encourage patients to adhere and commit to treatment in order to prevent irreversible complications of diabetes.

Factors contributing to non-adherence have become a priority for clinicians, healthcare policy makers, and healthcare payers alike. Patients who are non-adherent to their medication regimen appear to have poor health outcomes, with evidence of both high mortality rates and high morbidity in the form of more frequent emergency room admissions, recurrent exacerbations of disease, and poor overall well-being. The primary objective of this study was to identify and describe patient-identified factors associated with non-adherence in patients maintained on chronic hemodialysis. A 23-item questionnaire was developed and validated for use in the hemodialysis population. This questionnaire was administered to patients undergoing chronic hemodialysis in a single center during the period of October to December 2013. A total of 156/183 eligible patients consented. Of these 156 patients, 36 (23%) patients reported being non-adherent. The most common non-adherent behaviors were changing the frequency of taking medications and skipping doses. Patients identified information gaps around medication interactions, the flexibility around drug timings, and how best to manage medications that needed to be taken apart from, with, or without food. Our study shows that, despite an intensive drug education program, almost one quarter of patients continue to have problems with taking medication and that traditional education around medications is insufficient. We propose that clinicians customize education to the patient-driven gaps in knowledge, in particular focusing on the education needed to empower patients to recognize which aspects of their care they can and should modify and which aspects require further clinician input.

Background and aim Adherence to treatment is a critical component of epilepsy management. This study examines whether addressing antiepileptic drug (AED) side effects at every visit is associated with increased patient-reported medication adherence. Patients and methods This study identified 243 adults with epilepsy who were seen at two academic outpatient neurology settings and had at least two visits over a 3-year period. Demographic and clinical characteristics were abstracted. Evidence that AED side effects were addressed was measured through 1) phone interview (patient-reported) and 2) medical records abstraction (physician-documented). Medication adherence was assessed using the validated Morisky Medication Adherence Scale-4. Complete adherence was determined as answering “no” to all questions. Results Sixty-two (25%) patients completed the interviews. Participants and nonparticipants were comparable with respect to demographic and clinical characteristics; however, a smaller proportion of participants had a history of drug-resistant epilepsy than nonparticipants (17.7% vs 30.9%, P=0.04). Among the participants, evidence that AED side effects were addressed was present in 48 (77%) medical records and reported by 51 (82%) patients. Twenty-eight (45%) patients reported complete medication adherence. The most common reason for incomplete adherence was missed medication due to forgetfulness (n=31, 91%). There was no association between addressing AED side effects (neither physician-documented nor patient-reported) and complete medication adherence (P=0.22 and 0.20). Discussion and conclusion Among patients with epilepsy, addressing medication side effects at every visit does not appear to increase patient-reported medication adherence. PMID:27826186

Statin is an established treatment for secondary prevention after ischemic stroke. However, the effects of statin intensity and adherence on the long-term prognosis after acute stroke are not well known. This retrospective cohort study using a nationwide health insurance claim data in South Korea included patients admitted with acute ischemic stroke between 2002 and 2012. Statin adherence and intensity were determined from the prescription data for a period of 1 year after the index stroke. The primary outcome was a composite of recurrent stroke, myocardial infarction, and all-cause mortality. We performed multivariate Cox proportional regression analyses. We included 8001 patients with acute ischemic stroke. During the mean follow-up period of 4.69±2.72 years, 2284 patients developed a primary outcome. Compared with patients with no statin, adjusted hazard ratios (95% confidence interval) were 0.74 (0.64-0.84) for good adherence, 0.93 (0.79-1.09) for intermediate adherence, and 1.07 (0.95-1.20) for poor adherence to statin. Among the 1712 patients with good adherence, risk of adverse events was lower in patients with high-intensity statin (adjusted hazard ratio [95% confidence interval], 0.48 [0.24-0.96]) compared with those with low-intensity statin. Neither good adherence nor high intensity of statin was associated with an increased risk of hemorrhagic stroke. After acute ischemic stroke, high-intensity statin therapy with good adherence was significantly associated with a lower risk of adverse events. © 2017 American Heart Association, Inc.

Black race has been associated with decreased continuous positive airway pressure (CPAP) adherence. Short sleep duration, long sleep latency, and insomnia complaints may affect CPAP adherence as they affect sleep and opportunity to use CPAP. We assessed whether self-reported sleep measures were associated with CPAP adherence and if racial variations in these sleep characteristics may explain racial differences in CPAP adherence. Analysis of data from a randomized controlled trial (HomePAP), which investigated home versus laboratory-based diagnosis and treatment of obstructive sleep apnea. Seven American Academy of Sleep Medicine-accredited sleep centers in five cities in the United States. Enrolled subjects (n = 191) with apnea-hypopnea index ≥ 15 and sleepiness (Epworth Sleepiness Scale > 12). N/A. Multivariable regression was used to assess if subjective sleep measures and symptoms predicted 3-mo CPAP use. Mediation analysis was used to assess if sleep measures mediated the association of race with CPAP adherence. Black participants reported shorter sleep duration and longer sleep latency at baseline than white and Hispanic participants. Shorter sleep duration and longer sleep latency predicted worse CPAP adherence. Sleep duration mediated the association of black race with lower CPAP adherence. However, insomnia symptoms were not associated with race or CPAP adherence. Among subjects with similar severity of obstructive sleep apnea and sleepiness, baseline self-reported sleep duration and latency, but not perceived insomnia, predicted CPAP adherence over 3 mo. Sleep duration explains some of the observed differences in CPAP use by race. Sleep duration and latency should be considered when evaluating poor CPAP adherence.

As lifelong antiretroviral therapy (ART) for pregnant women is implemented, it is important to understand the attitudes and norms affecting women's postpartum ART adherence. This is a qualitative cross-sectional study of HIV-positive postpartum women (n = 112) enrolled in a 2-year observational prospective cohort in Rwanda. Informed by the Theory of Reasoned Action (TRA), we conducted in-depth interviews with women whose children were 0-6, 7-12, 13-18, or 21-24 months of age to describe factors contributing to adherence and changes over time. Positive ART attitudes reported by women included mothers' health promotion, prevention of infant HIV infection, higher CD4 count, and improved physical appearance. Negative attitudes were few, but included side effects and the lifelong nature of treatment. Learning from people living with HIV (PLHIV) was identified as a norm facilitating adherence; ART adherence was inhibited by fear of disclosure or stigmatization in communities and clinics. Poor adherence behaviors were common immediately after HIV diagnosis, not necessarily during prevention of mother-to-child transmission (PMTCT). Women with older children, most of whom stopped breastfeeding by 13-18 months, reported more barriers and missed doses than women with younger children. The TRA was useful in identifying the collective influence of attitudes, norms, and intentions on behavior. Findings suggest that HIV-positive women are vulnerable to poor adherence following HIV diagnosis and around the time of breastfeeding cessation. Lifelong treatment adherence can be supported through PLHIV exemplifying long-term ART use, fewer and less stigmatizing clinic visits, and counseling messages highlighting the benefits of drugs on appearance and illness prevention and incorporating biological feedback.

Rheumatoid arthritis (RA) is a common chronic inflammatory disease causing joint damage, disability, and reduced life expectancy. Highly effective drugs are now available for the treatment of RA. However, poor adherence to drug regimens remains a significant barrier to improving clinical outcomes in RA. Poor adherence has been shown to be linked to patients' beliefs about medicines with a potential impact on adherence. These beliefs are reported to be different between ethnic groups. The purpose of this study was to identify potential determinants of adherence to disease modifying anti-rheumatic drugs (DMARDs) including an assessment of the influence of beliefs about medicines and satisfaction with information provided about DMARDs and compare determinants of adherence between RA patients of White British and South Asian. RA patients of either White British (n = 91) or South Asian (n = 89) origin were recruited from secondary care. Data were collected via questionnaires on patients': (1) self-reported adherence (Medication Adherence Report Scale-MARS); (2) beliefs about medicines (Beliefs about Medicines Questionnaire-BMQ); (3) illness perceptions (Illness Perceptions Questionnaire-IPQ) and (4) satisfaction with information about DMARDs (Satisfaction with Information about Medicines questionnaire-SIMS). In addition, clinical and demographic data were collected. The results revealed that socio-demographic factors only explained a small amount of variance in adherence whereas illness representations and treatment beliefs were more substantial in explaining non-adherence to DMARDs. Patients' self-reported adherence was higher in White British than South Asian patients (median 28 (interquartile range 26-30) vs median 26 (interquartile range 23-30) respectively; P = 0.013, Mann-Whitney test). Patients who reported lower adherence were more dissatisfied with the information they had received about their DMARDs (P < 0.001, Spearman correlation, SIMS action and usage

ABSTRACT OBJECTIVE To analyze factors associated with low adherence to drug treatment for chronic diseases in Brazil. METHODS Analysis of data from Pesquisa Nacional sobre Acesso, Utilização e Promoção do Uso Racional de Medicamentos (PNAUM - Brazilian Survey on Access, Use and Promotion of Rational Use of Medicines), a population-based cross-sectional household survey, based on a probabilistic sample of the Brazilian population. We analyzed the association between low adherence to drug treatment measured by the Brief Medication Questionnaire and demographic, socioeconomic, health, care and prescription factors. We used Poisson regression model to estimate crude and adjusted prevalence ratios, their respective 95% confidence interval (95%CI) and p-value (Wald test). RESULTS The prevalence of low adherence to drug treatment for chronic diseases was 30.8% (95%CI 28.8-33.0). The highest prevalence of low adherence was associated with individuals: young adults; no education; resident in the Northeast and Midwest Regions of Brazil; paying part of the treatment; poor self-perceived health; three or more diseases; reported limitations caused by a chronic disease; using five drugs or more. CONCLUSIONS Low adherence to drug treatment for chronic diseases in Brazil is relevant, and regional and demographic differences and those related to patients’ health care and therapy regime require coordinated action between health professionals, researchers, managers and policy makers.

Poor adherence to oral adjuvant hormonal therapy for breast cancer is a common problem, but little is known about the relationship between self-report adherence measures and hormonal suppression. We evaluated the relationship of three self-report measures of medication adherence and oestrogen among patients on aromatase inhibitors (AIs). We recruited 235 women with breast cancer who were prescribed AI therapy. Participants self-reported AI adherence by completing the following: (1) a single item asking whether they took an AI in the last month, (2) a modified Morisky Medication Adherence Scale-8 (MMAS-8) and (3) the Visual Analog Scale (VAS). Serum estrone and estradiol were analysed using organic solvent extraction and Celite column partition chromatography, followed by radioimmunoassay. Ten percent of participants reported they had not taken an AI in the last month and among this group, median estrone (33.2 pg/ml [interquartile range (IQR)=22.3]) and estradiol levels (7.2 pg/mL [IQR=3.3]) were significantly higher than those in participants who reported AI use (median estrone=11.5 pg/mL [IQR=4.9]; median estradiol=3.4 pg/mL [IQR=2.1]; p<0.001). This relationship held when controlling for race and AI drug type. A single-item monthly-recall adherence measure for AIs was associated with oestrogen serum levels. This suggests that patient-reported monthly adherence may be a useful measure to identify early non-adherence behaviour and guide interventions to improve patient adherence to hormonal treatment.

The extent to which low medication adherence in hypertensive individuals contributes to disparities in stroke and transient ischemic attack (TIA) risk is poorly understood. Investigators examined the relationship between self-reported medication adherence and blood pressure (BP) control (<140/90 mm Hg), Framingham Stroke Risk Score, and physician-adjudicated stroke/TIA incidence in treated hypertensive subjects (n = 15,071; 51% black; 57% in Stroke Belt) over 4.9 years in the national population-based REGARDS cohort study. Mean systolic BP varied from 130.8 ± 16.2 mm Hg in those reporting high adherence to 137.8 ± 19.5 mm Hg in those reporting low adherence (P for trend < .0001). In logistic regression models, each level of worsening medication adherence was associated with significant and increasing odds of inadequately controlled BP (≥140/90 mm Hg; score = 1, odds ratio [95% confidence interval], 1.20 [1.09-1.30]; score = 2, 1.27 [1.08-1.49]; score = 3 or 4, 2.21 [1.75-2.78]). In hazard models using systolic BP as a mediator, those reporting low medication adherence had 1.08 (1.04-1.14) times greater risk of stroke and 1.08 (1.03-1.12) times greater risk of stroke or TIA. Low medication adherence was associated with inadequate BP control and an increased risk of incident stroke or TIA. Copyright © 2013 American Society of Hypertension. Published by Elsevier Inc.

Summary The purpose of this study is to examine the effect of PTH(1–84) treatment over 24 months followed by 12 months discontinuation on BMD, bone turnover markers, fractures and the impact of adherence on efficacy. Introduction There is limited information about the effect of PTH(1-84) after 18 months and limited data about the impact of compliance on response to anabolic therapy. Methods Seven hundred and eighty-one subjects who received active PTH(1–84) in the Treatment of Osteoporosis with Parathyroid hormone trial for approximately 18 months were entered into a 6-month open-label extension. Thereafter, they were followed for 12 additional months after discontinuation of treatment. Endpoints examined included changes in BMD and biochemical markers. Results PTH(1–84) treatment over 24 months increased BMD at the lumbar spine by 6.8 % above baseline (p < 0.05). The total corresponding BMD increases at the hip and femoral neck were 1.1 and 2.2% above baseline. Larger increases in spine BMD were observed in participants with ≥80 % adherence to daily injections of PTH(1–84) (8.3% in adherent vs 4.9 % in poorly adherent patients). Total hip BMD gains were 1.7 % in adherent vs 0.6 % in poorly adherent participants. Markers of bone turnover (BSAP and NTx) peaked 6 months after starting PTH(1–84) treatment and declined slowly but remained above baseline at 24 months. After discontinuation of PTH(1–84) treatment (at 24 months), bone turnover markers returned to near baseline levels by 30 months. The adherent group sustained significantly fewer fractures than the poorly adherent group. Conclusions PTH(1–84) treatment over 24 months results in continued increases in lumbar spine BMD. Adherence to treatment with PTH(1–84) for up to 24 months is also associated with greater efficacy. PMID:22930240

Bacteria attached to a surface are generally more tolerant to antibiotics than their planktonic counterparts, even without the formation of a biofilm. The mechanism of antibiotic tolerance in biofilm communities is multifactorial, and the genetic background underlying this antibiotic tolerance has not yet been fully elucidated. Using transposon mutagenesis, we isolated a mutant with reduced tolerance to biapenem (relative to that of the wild type) from adherent cells. Sequencing analysis revealed a mutation in the pslL gene, which is part of the polysaccharide biosynthesis operon. The Pseudomonas aeruginosa PAO1Δ pslBCD mutant demonstrated a 100-fold-lower survival rate during the exposure of planktonic and biofilm cells to biapenem; a similar phenotype was observed in a mouse infection model and in clinical strains. Transcriptional analysis of adherent cells revealed increased expression of both pslA and pelA , which are directly regulated by bis-(3',5')-cyclic dimeric GMP (c-di-GMP). Inactivation of wspF resulted in significantly increased tolerance to biapenem due to increased production of c-di-GMP. The loss of pslBCD in the Δ wspF mutant background abolished the biapenem-tolerant phenotype of the Δ wspF mutant, underscoring the importance of psl in biapenem tolerance. Overexpression of PA2133, which can catalyze the degradation of c-di-GMP, led to a significant reduction in biapenem tolerance in adherent cells, indicating that c-di-GMP is essential in mediating the tolerance effect. The effect of pslBCD on antibiotic tolerance was evident, with 50- and 200-fold-lower survival in the presence of ofloxacin and tobramycin, respectively. We speculate that the psl genes, which are activated by surface adherence through elevated intracellular c-di-GMP levels, confer tolerance to antimicrobials.

Background High levels of patient adherence to antimalarial treatment are important in ensuring drug effectiveness. To achieve this goal, it is important to understand levels of patient adherence, and the range of study designs and methodological challenges involved in measuring adherence and interpreting results. Since antimalarial adherence was reviewed in 2004, there has been a major expansion in the use of artemisinin-based combination therapies (ACTs) in the public sector, as well as initiatives to make them more widely accessible through community health workers and private retailers. These changes and the large number of recent adherence studies raise the need for an updated review on this topic. Objective We conducted a systematic review of studies reporting quantitative results on patient adherence to antimalarials obtained for treatment. Results The 55 studies identified reported extensive variation in patient adherence to antimalarials, with many studies reporting very high adherence (90–100%) and others finding adherence of less than 50%. We identified five overarching approaches to assessing adherence based on the definition of adherence and the methods used to measure it. Overall, there was no clear pattern in adherence results by approach. However, adherence tended to be higher among studies where informed consent was collected at the time of obtaining the drug, where patient consultations were directly observed by research staff, and where a diagnostic test was obtained. Conclusion Variations in reported adherence may reflect factors related to patient characteristics and the nature of their consultation with the provider, as well as methodological variations such as interaction between the research team and patients before and during the treatment. Future studies can benefit from an awareness of the impact of study procedures on adherence outcomes, and the identification of improved measurement methods less dependent on self-report.

This study aims to identify factors associated with poor adherence to COPD treatment in patients receiving a fixed-dose combination (FDC) of inhaled corticosteroids and long-acting β2-agonist (ICS/LABA), focusing on the importance of inhaler devices. We conducted a retrospective and multicenter study based on a review of medical registries between 2007 and 2012 of COPD patients (n=1,263) treated with ICS/LABA FDC, whose medical devices were either dry powder inhalers (DPIs) or pressurized metered-dose inhalers (pMDI). Medication adherence included persistence outcomes through 18 months and medication possession ratios. Data on exacerbations, comorbidities, demographic characteristics, and health care resource utilization were also included as confounders of adherence. The analyses revealed that COPD patients whose medication was delivered through a DPI were less likely to have medication adherence compared to patients with pMDI, after adjusting for confounding factors, especially active ingredients. Younger groups of patients were less likely to be adherent compared to the oldest group. Smoker men were less likely to be adherent compared to women and non-smokers. Comorbidities decreased the probability of treatment adherence. Those patients that visited their doctor once a month were more likely to adhere to their medication regimen; however, suboptimal adherence was more likely to occur among those patients who visited more than three times per month their doctor. We also found that worsening of COPD is negatively associated with adherence. According to this study, inhaler devices influence patients' adherence to long-term COPD medication. We also found that DPIs delivering ICS/LABA FDC had a negative impact on adherence. Patients' clinic and socioeconomic characteristics were associated with adherence.

Antiretroviral adherence is the second strongest predictor of progression to acquired immunodeficiency syndrome (AIDS) and death, after CD4 count. Adherence to antiretroviral therapy (ART) has been strongly correlated with human immunodeficiency virus (HIV) viral suppression, reduced rates of resistance, an increase in survival, and improved quality of life. To determine the adherence rates and factors affecting adherence to ART among people living with HIV/AIDS (PLWHA). A Prospective study for 1 year was conducted among PLWHA, aged between 15 and 49 years, visiting ART center. 242 PLWHAs were included in the study. Structured questionnaire was used to obtain data on sociodemographic profile, factors affecting adherence. Adherence was assessed through self-reports, routine and random pill counts, and assessment of medical records. Descriptive statistics, logistic regression, and Chi-square tests were computed using Epi Info 7 version CDC (Centers for Disease Control and Prevention) U.S. Department of Health and Human Services. Adherence to ART was finally assessed on 242 PLWHAs. Mean age of subjects was 35 ± 7.8 years. One hundred percent adherence rate (consistent adherers) for the whole 6 month period was seen only in 31.6% patients. Lower 6 month averages of 95-100%, 80-95%, and <80% were noted in 49.8%, 9.1%, and 9.5% patients, thus resulting in optimal adherence rate of >95% in 81.4%. Earning member (odds ratio [OR] =0.404) and weight difference (OR = 0.818) were most associated with the adherent individuals. Most common psychological reason was forgetfulness in 44.9%. Adherence rate was poor among PLWHA and economic factors play an important role in adherence.

Background Several studies have investigated the factors associated with adherence to antidepressants, with inconsistent conclusions. However, no similar study has investigated this issue among patients diagnosed with major depressive disorder in Saudi Arabia. The aim of this study is to explore patients’ adherence to antidepressant medications, and the factors associated with adherence. Methods A non-experimental cross-sectional design was used to measure adherence to antidepressants among major depressive disorder patients, and the factors associated with adherence. The patients were recruited from the outpatient clinic at the Al-Amal Complex for Mental Health in Riyadh, Saudi Arabia, between August 2013 and January 2014. Eligible participants met with one of the research coordinators for assessment of their adherence. Adherence was investigated indirectly by use of the Morisky Medication Adherence Scale, and patients’ beliefs were assessed through the Beliefs about Medicine Questionnaire. Information about the severity of their depression, demographics, and other study variables were collected. Results A total of 403 patients met the inclusion criteria and participated in the study. Of those, 203 (50.37%) were females, while the remaining 200 (49.6%) were males. There was an average age of 39 years (standard deviation, ±11 years). Half of the patients (52.9%) reported low adherence to their antidepressant medication, with statistically significant differences between the low adherence and high adherence scores relating to sex, age, and duration of illness. Conclusion Low medication adherence is a common problem among major depressive disorder patients in Saudi Arabia. Medication-taking behavior among depressed patients is influenced by several factors, mainly patients’ beliefs regarding antidepressants. This study has improved the understanding of the factors associated with adherence to antidepressants. PMID:25378929

Poor antidepressant adherence is a significant issue in depression treatment that adversely affects treatment outcomes. While being a common problem, it tends to be more common among Latinos. To address this problem, the current study adapted a Motivational Interviewing (MI) intervention to improve adherence among Latinos with depression. The adaptation process included six focus groups that elicited participants’ perspectives (N = 30), applying the intervention with test cases (N = 7) to fine tune the intervention, and eliciting feedback on the intervention (N = 5). The findings generated from these adaptation phases are described, along with a case example. Examples of adaptations to the MI included reframing antidepressant adherence as a way to luchar (struggle) against problems, focusing on motivation for improving depression and not just medication, refining methods for imparting antidepressant information, and inclusion of personalized visual feedback on dose-taking. The findings provide a description of the antidepressant issues experienced by a group of Latinos, as well as considerations for applying MI with this population. The intervention remained grounded in MI principles, but was contextualized for this Latino group. PMID:20438160

Background Although many studies have identified patient characteristics or chronic diseases associated with medication adherence, the clinical utility of such predictors has rarely been assessed. We attempted to develop clinical prediction rules for adherence with antihypertensive medications in two health care delivery systems. Methods and Results Retrospective cohort studies of hypertension registries in an inner-city health care delivery system (N = 17176) and a health maintenance organization (N = 94297) in Denver, Colorado. Adherence was defined by acquisition of 80% or more of antihypertensive medications. A multivariable model in the inner-city system found that adherent patients (36.3% of the total) were more likely than non-adherent patients to be older, white, married, and acculturated in US society, to have diabetes or cerebrovascular disease, not to abuse alcohol or controlled substances, and to be prescribed less than three antihypertensive medications. Although statistically significant, all multivariate odds ratios were 1.7 or less, and the model did not accurately discriminate adherent from non-adherent patients (C-statistic = 0.606). In the health maintenance organization, where 72.1% of patients were adherent, significant but weak associations existed between adherence and older age, white race, the lack of alcohol abuse, and fewer antihypertensive medications. The multivariate model again failed to accurately discriminate adherent from non-adherent individuals (C-statistic = 0.576). Conclusions Although certain socio-demographic characteristics or clinical diagnoses are statistically associated with adherence to refills of antihypertensive medications, a combination of these characteristics is not sufficiently accurate to allow clinicians to predict whether their patients will be adherent with treatment.

Depression, global neurocognitive (GNC) function, and substance use disorders (SUDs) are each associated with medication adherence in persons living with HIV (PLWH). Because somatic symptoms can inflate depression scores in PLWH, the role of nonsomatic depressive symptomatology (NSDS) should be considered in adherence. However, the combined roles of NSDS, GNC function, and current SUDs in predicting combined antiretroviral therapy (cART) adherence remain poorly understood. Forty PLWH (70% Latina/o; 30% non-Hispanic White) completed psychiatric/SUD, neurocognitive, and self-report cART adherence evaluations. Higher NSDS was associated with suboptimal adherence (p < .01), but optimal and suboptimal adherers did not differ in GNC function or current SUDs. Only NSDS was associated with suboptimal adherence, after accounting for GNC function and SUDs (p = .01). NSDS uniquely predicted self-reported adherence, beyond GNC function and current SUDs among ethnically diverse PLWH. Methodological issues between present and prior studies should also be considered.

To assess adherence to community-based directly observed treatment (DOT) among Tanzanian tuberculosis patients using the Medication Event Monitoring System (MEMS) and to validate alternative adherence measures for resource-limited settings using MEMS as a gold standard. This was a longitudinal pilot study of 50 patients recruited consecutively from one rural hospital, one urban hospital and two urban health centres. Treatment adherence was monitored with MEMS and the validity of the following adherence measures was assessed: isoniazid urine test, urine colour test, Morisky scale, Brief Medication Questionnaire, adapted AIDS Clinical Trials Group (ACTG) adherence questionnaire, pill counts and medication refill visits. The mean adherence rate in the study population was 96.3% (standard deviation, SD: 7.7). Adherence was less than 100% in 70% of the patients, less than 95% in 21% of them, and less than 80% in 2%. The ACTG adherence questionnaire and urine colour test had the highest sensitivities but lowest specificities. The Morisky scale and refill visits had the highest specificities but lowest sensitivities. Pill counts and refill visits combined, used in routine practice, yielded moderate sensitivity and specificity, but sensitivity improved when the ACTG adherence questionnaire was added. Patients on community-based DOT showed good adherence in this study. The combination of pill counts, refill visits and the ACTG adherence questionnaire could be used to monitor adherence in settings where MEMS is not affordable. The findings with regard to adherence and to the validity of simple adherence measures should be confirmed in larger populations with wider variability in adherence rates.

Background Antiretroviral therapy (ART) is a lifesaver for individual patients treated for Human Immunodeficiency Virus (HIV) and Acquired Immune Deficiency Syndrome (AIDS). Maintaining optimal adherence to antiretroviral drugs is essential for HIV infection management. This study aimed to understand the factors influencing adherence amongst ART-prescribed patients and care providers in Nepal. Methods A cross-sectional mixed-methods study surveying 330 ART-prescribed patients and 34 in-depth interviews with three different types of stakeholders: patients, care providers, and key people at policy level. Adherence was assessed through survey self-reporting and during the interviews. A multivariate logistic regression model was used to identify factors associated with adherence, supplemented with a thematic analysis of the interview transcripts. Results A total of 282 (85.5%) respondents reported complete adherence, i.e. no missed doses in the four-weeks prior to interview. Major factors influencing adherence were: non-disclosure of HIV status (OR = 17.99, p =  0.014); alcohol use (OR = 12.89, p = <0.001), being female (OR = 6.91, p = 0.001), being illiterate (OR = 4.58, p = 0.015), side-effects (OR = 6.04, p = 0.025), ART started ≤24 months (OR = 3.18, p = 0.009), travel time to hospital >1 hour (OR = 2.84, p = 0.035). Similarly, lack of knowledge and negative perception towards ART medications also significantly affected non-adherence. Transport costs (for repeat prescription), followed by pills running out, not wanting others to notice, side-effects, and being busy were the most common reasons for non-adherence. The interviews also revealed religious or ritual obstacles, stigma and discrimination, ART-associated costs, transport problems, lack of support, and side-effects as contributing to non-adherence. Conclusion Improving adherence requires a supportive environment; accessible treatment; clear

Adherence to antiretroviral (ARV) therapy for HIV infection is critical for maximum benefit from treatment and for the prevention of HIV-related complications. There is evidence that many factors determine medication adherence, including adherence self-efficacy (confidence in one's ability to adhere) and relations with health care providers. However, there are no studies that examine how these two factors relate to each other and their subsequent influence on HIV medication adherence. The goal of the current analysis was to explore a model of medication adherence in which the relationship between positive provider interactions and adherence is mediated by adherence self-efficacy. Computerized self administered and interviewer administered self reported measures of medication adherence, demographic and treatment variables, provider interactions, and adherence self-efficacy were administered to 2765 HIV infected adults on ARV. Criteria for mediation were met, supporting a model in which adherence self-efficacy is the mechanism for the relationship between positive provider interactions and adherence. The finding was consistent when the sample was stratified by gender, race, injection drug use history, and whether the participant reported receipt of HIV specialty care. Positive provider interactions may foster greater adherence self-efficacy, which is associated with better adherence to medications. Results suggest implications for improving provider interactions in clinical care, and future directions for clarifying inter-relationships among provider interactions, adherence self-efficacy, and medication adherence are supported.

Background Scale-up of highly active antiretroviral treatment therapy (HAART) programs in Rwanda has been highly successful but data on adherence is limited. We examined HAART adherence in a large cohort of HIV+ Rwandan women. Methods The Rwanda Women's Interassociation Study Assessment (RWISA) was a prospective cohort study that assessed effectiveness and toxicity of ART. We analyzed patient data 12±3 months after HAART initiation to determine adherence rates in HIV+ women who had initiated HAART. Results Of the 710 HIV+ women at baseline, 490 (87.2%) initiated HAART. Of these, 6 (1.2%) died within 12 months, 15 others (3.0%) discontinued the study and 80 others (19.0%) remained in RWISA but did not have a post-HAART initiation visit that fell within the 12±3 month time points leaving 389 subjects for analysis. Of these 389, 15 women stopped their medications without being advised to do so by their doctors. Of the remaining 374 persons who reported current HAART use 354 completed the adherence assessment. All women, 354/354, reported 100% adherence to HAART at the post-HAART visit. The high self-reported level of adherence is supported by changes in laboratory measures that are influenced by HAART. The median (interquartile range) CD4 cell count measured within 6 months prior to HAART initiation was 185 (128, 253) compared to 264 (182, 380) cells/mm3 at the post-HAART visit. Similarly, the median (interquartile range) MCV within 6 months prior to HAART initiation was 88 (83, 93) fL compared to 104 (98, 110) fL at the 12±3 month visit. Conclusion Self-reported adherence to antiretroviral treatment 12±3 months after initiating therapy was 100% in this cohort of HIV-infected Rwandan women. Future studies should explore country-specific factors that may be contributing to high levels of adherence to HAART in this population. PMID:22114706

Treatment adherence and insight in schizophrenia.

Lack of adherence to treatment in patients with schizophrenia is a major risk factor for poor outcome, including relapse, rehospitalization, and suicide. Poor insight into illness may be a leading cause for partial- or nonadherence since a high proportion of patients with schizophrenia are partially or completely unaware of their mental disorder. The primary objective was to estimate the impact of lack of insight on adherence to medication based on a population of patients in Hungary who had the diagnosis of schizophrenia. The secondary objective was to investigate the association of the different aspects of insight (awareness of illness, the capacity to relabel psychotic experiences as abnormal, treatment acceptance) with (1) recent adherence behavior; (2) current mental state; (3) remission/non-remission status as measured by remission severity criteria; and (4) demographic and treatment history data. This was cross-sectional, noninterventional study, carried out under daily clinical practice conditions, with no influence exerted upon clinical practice in view of the observational nature of the study. Eligibility criteria included: a) patients' age (>18 years), b) diagnosis of schizophrenia (ICD-10), c) signed informed consent, d) no concomitant participation in another clinical trial. Study sites represented Mental Health Centers and outpatient clinics of hospital psychiatric units. Each investigator was asked to enroll patients consecutively. The final analysis sample comprised 262 patients, distributed across 13 sites. The following data were collected: general sociodemographic and clinical data (age, sex, level of education, socioeconomic situation, family support, psychiatric diagnosis, years of evolution, pharmacological and/or psychosocial treatments at the time of inclusion in the study, previous psychiatric admissions), with assessments of the Schedule of Assessing components of Insight (SAI), Compliance Rating Scale (CRS), Clinical Global Impression

Utilization of Medical Treatments and Adherence to Antiretroviral Therapy among HIV-Positive Adults with Histories of Childhood Sexual Abuse

Hansen, Nathan B.; Kochman, Arlene; Sikkema, Kathleen J.

2009-01-01

Abstract HIV is a chronic, life-threatening illness that necessitates regular and consistent medical care. Childhood sexual abuse (CSA) is a common experience among HIV-positive adults and may interfere with treatment utilization. This study examined rates and correlates of treatment utilization among HIV-positive adults with CSA enrolled in a coping intervention trial in New York City. The baseline assessment included measures of treatment utilization, mental health, substance abuse, and other psychosocial factors. In 2002–2004, participants (50% female, 69% African-American, M = 42.3 ± 6.8 years old) were recruited. Nearly all (99%) received HIV medical care. However, 20% had no outpatient visits and 24% sought emergency services in the past 4 months. Among 184 participants receiving antiretroviral therapy (ART), 22% were less than 90% adherent in the past week. In a multivariable logistic regression model, no outpatient treatment was associated with African American race (AOR = 3.46 [1.42–8.40]), poor social support (AOR = 1.59 [1.03–2.45]), and abstinence from illicit drug use (AOR = 0.37 [0.16–0.85]). Emergency service utilization was associated with HIV symptoms (AOR = 2.30 [1.22–4.35]), binge drinking (AOR=2.92 (1.18–7.24)), and illicit drug use (AOR = 1.98 [1.02–3.85]). Poor medication adherence was associated with trauma symptoms (AOR = 2.64 [1.07–6.75]) and poor social support (AOR = 1.82 [1.09–2.97]). In sum, while participants had access to HIV medical care, a sizable minority did not adhere to recommended guidelines and thus may not be benefiting optimally from treatment. Interventions targeting HIV-positive adults with CSA histories may need to address trauma symptoms, substance abuse, and poor social support that interfere with medical treatment utilization and adherence.
