    Context Early hospital readmission is emerging as an indicator of care quality. Some children with chronic illnesses may be readmitted on a recurrent basis, but there are limited data describing their rehospitalization patterns and impact. Objectives To describe the inpatient resource utilization, clinical characteristics, and admission reasons of patients recurrently readmitted to children’s hospitals. Design, Setting, and Patients Retrospective cohort analysis of 317 643 patients (n=579 504 admissions) admitted to 37 US children’s hospitals in 2003 with follow-up through 2008. Main Outcome Measure Maximum number of readmissions experienced by each child within any 365-day interval during the 5-year follow-up period. Results In the sample, 69 294 patients (21.8%) experienced at least 1 readmission within 365 days of a prior admission. Within a 365-day interval, 9237 patients (2.9%) experienced 4 or more readmissions; time between admissions was a median 37 days (interquartile range [IQR], 21–63). These patients accounted for 18.8% (109 155 admissions) of all admissions and 23.2% ($3.4 billion) of total inpatient charges for the study cohort during the entire follow-up period. Tests for trend indicated that as the number of readmissions increased from 0 to 4 or more, the prevalences increased for a complex chronic condition (from 22.3% [n=55 382/248 349] to 89.0% [n=8225/9237]; P <.001), technology assistance (from 5.3% [n = 13 163] to 52.6% [n=4859]; P <.001), public insurance use (from 40.9% [n = 101 575] to 56.3% [n=5202]; P <.001), and non-Hispanic black race (from 21.8% [n=54 140] to 34.4% [n=3181]; P <.001); and the prevalence decreased for readmissions associated with an ambulatory care–sensitive condition (from 23.1% [62 847/272 065] to 14.0% [15 282/109 155], P<.001). Of patients readmitted 4 or more times in a 365-day interval, 2633 (28.5%) were rehospitalized for a problem in the same organ system across all admissions during the interval

    A systematic review identified studies eliciting utility decrements from myocardial infarction (MI) and stroke in patients with Type 2 diabetes mellitus (T2DM) and examined their use in economic models of new diabetes treatments. In 16 utility studies in patients with T2DM, utility decrements in the first year ranged from 0.017 to 0.226 for MI and from 0.034 to 0.590 for stroke. Sixteen of 19 economic evaluations of new treatments for T2DM included utility decrements for an MI and/or stroke from one of the 16 utility studies. Decrements for MI ranged from 0.012 to 0.180 in the first year. Decrements for stroke ranged from 0.044 to 0.690 in the first year. Utility studies in patients with T2DM provide little information about changes in utility decrements by time since the event and by disease severity. Cost-effectiveness studies do not always indicate how these values were used in the analysis.

    Economic theory distinguishes two concepts of utility: decision utility, objectively quantifiable by choices, and experienced utility, referring to the satisfaction by an obtainment. To date, experienced utility is typically measured with subjective ratings. This study intended to quantify experienced utility by global levels of neuronal activity. Neuronal activity was measured by means of electroencephalographic (EEG) responses to gain and omission of graded monetary rewards at the level of the EEG topography in human subjects. A novel analysis approach allowed approximating psychophysiological value functions for the experienced utility of monetary rewards. In addition, we identified the time windows of the event-related potentials (ERP) and the respective intracortical sources, in which variations in neuronal activity were significantly related to the value or valence of outcomes. Results indicate that value functions of experienced utility and regret disproportionally increase with monetary value, and thus contradict the compressing value functions of decision utility. The temporal pattern of outcome evaluation suggests an initial (∼250 ms) coarse evaluation regarding the valence, concurrent with a finer-grained evaluation of the value of gained rewards, whereas the evaluation of the value of omitted rewards emerges later. We hypothesize that this temporal double dissociation is explained by reward prediction errors. Finally, a late, yet unreported, reward-sensitive ERP topography (∼500 ms) was identified. The sources of these topographical covariations are estimated in the ventromedial prefrontal cortex, the medial frontal gyrus, the anterior and posterior cingulate cortex and the hippocampus/amygdala. The results provide important new evidence regarding "how," "when," and "where" the brain evaluates outcomes with different hedonic impact.

    Even though Greece has a disproportionate number of haemodialysis stations for the treatment of end-stage renal disease (ESRD), and a rapidly rising number of patients on dialysis, there has been no study of the lived experience of haemodialysis treatment in Greece. ESRD and dialysis drastically impact patients' everyday life, therefore expectations and desires play a major role in adapting to alterations and restrictions. An understanding of these culturally-influenced expectations and desires is essential for the delivery of holistic nursing care. This study aimed to explore how Greek patients receiving long-term haemodialysis perceived their problems and to describe the impact of haemodialysis on their lives. Using a grounded theory approach, 23 patients with ESRD receiving haemodialysis were purposively recruited from two hospital dialysis centres in Athens, Greece. Data were collected during 2006 by personal interviews. Given a distinctive patient experience of haemodialysis, some insight into their common concerns can facilitate provision of healthcare services that adequately meets their needs. By developing an understanding of the experience of renal illness and therapy for a group of people using dialysis, this study was intended as a contribution towards enabling healthcare professionals to provide more effective support to people who are living with this chronic condition.

  6. An anatomy of old-age disability: Time use, affect and experienced utility.

    Complementing the commonly used concepts of evaluative wellbeing and decision utility, emotional wellbeing and experienced utility are important welfare criteria to assess individuals' subjective wellbeing, especially for valuing health and disability. Yet, almost all empirical evidences on the link between disability and experienced wellbeing come from developed countries. This paper studies the relationship between old-age disability and experienced utility in five low- and middle-income countries. Using data on individual time use and activity-specific affective experiences from an abbreviated version of the Day Reconstruction Method, we document a strong negative association between disability and experienced utility. These differences in experienced utility by disability status are exclusively due to worse activity-specific affective experiences among persons with disabilities. By contrast, disability-related differences in time use provide small compensating effects. Interventions or technologies that facilitate daily life hold most promise to improve experienced utility among persons with disabilities in the developing world.

  7. Physicians Experiencing Intense Emotions While Seeing Their Patients: What Happens?

    Objectives: Physicians often deal with emotions arising from both patients and themselves; however, management of intense emotions when they arise in the presence of patients is overlooked in research. The aim of this study is to inspect physicians’ intense emotions in this context, how these emotions are displayed, coping strategies used, adjustment behaviors, and the impact of the emotional reactions on the physician-patient relationship. Methods: A total of 127 physicians completed a self-report survey, built from a literature review. Participants were recruited in 3 different ways: through a snowball sampling procedure, via institutional e-mails, and in person during service meetings. Results: Fifty-two physicians (43.0%) reported experiencing intense emotions frequently. Although most physicians (88.6%) tried to control their reactions, several reported not controlling themselves. Coping strategies to deal with the emotion at the moment included behavioral and cognitive approaches. Only the type of reaction (but not the emotion’s valence, duration, relative control, or coping strategies used) seemed to affect the physician-patient relationship. Choking-up/crying, touching, smiling, and providing support were significantly associated with an immediate positive impact. Withdrawing from the situation, imposing, and defending oneself were associated with a negative impact. Some reactions also had an extended impact into future interactions. Conclusion: Experiencing intense emotions in the presence of patients was frequent among physicians, and the type of reaction affected the clinical relationship. Because many physicians reported experiencing long-lasting emotions, these may have important clinical implications for patients visiting physicians while these emotions last. Further studies are needed to clarify these results. PMID:27479947

    Background Patients undergoing treatment for malignant gliomas (MGs) can encounter medical costs beyond what their insurance covers. The magnitude and type of costs experienced by patients are unknown. The purpose of this study was to have patients or their families report on the medical costs incurred during the patients MG treatment. Methods Patients with MG were eligible if they were within 6 months of diagnosis or tumor recurrence. Patients had to be ≥18 years of age, fluent in English, and not aphasic. Weekly logbooks were issued to patients for recording associated costs for ∼6 months or until tumor progression. “Out-of-pocket” (OOP) costs included medical and nonmedical expenses that were not reimbursed by insurance. Direct medical costs included hospital and physician bills. Direct nonmedical costs included transportation, parking, and other related items. Indirect medical costs included lost wages. Costs were analyzed to provide mean and medians with range of expenses. Results Forty-three patients provided cost data for a median of 12 weeks. There were 25 men and 18 women with a median age of 57 years (range, 24y–73y); 79% were married, and 49% reported annual income >$75 000. Health insurance coverage was preferred provider organizations for 58% of patients, and median deductible was $1 500. Median monthly OOP cost was $1 342 (mean, $2 451; range, $333.41–$17 267.16). The highest OOP median costs were medication copayments ($710; range, $0–13 611.20), transportation ($327; range, $0–$1 927), and hospital bill copayments ($403; range, $0–$4 000). Median lost wages were $7 500, and median lost days of work were 12.8. Conclusions OOP costs for MG patients can be significant and comprise direct and indirect costs across several areas. Informing patients about expected costs could limit additional duress and allow financial support systems to be implemented. PMID:26034619

    Objectives Environmental sound perception serves an important ecological function by providing listeners with information about objects and events in their immediate environment. Environmental sounds such as car horns, baby cries or chirping birds can alert listeners to imminent dangers as well as contribute to one's sense of awareness and well being. Perception of environmental sounds as acoustically and semantically complex stimuli, may also involve some factors common to the processing of speech. However, very limited research has investigated the abilities of cochlear implant (CI) patients to identify common environmental sounds, despite patients' general enthusiasm about them. This project (1) investigated the ability of patients with modern-day CIs to perceive environmental sounds, (2) explored associations among speech, environmental sounds and basic auditory abilities, and (3) examined acoustic factors that might be involved in environmental sound perception. Design Seventeen experienced postlingually-deafened CI patients participated in the study. Environmental sound perception was assessed with a large-item test composed of 40 sound sources, each represented by four different tokens. The relationship between speech and environmental sound perception, and the role of working memory and some basic auditory abilities were examined based on patient performance on a battery of speech tests (HINT, CNC, and individual consonant and vowel tests), tests of basic auditory abilities (audiometric thresholds, gap detection, temporal pattern and temporal order for tones tests) and a backward digit recall test. Results The results indicated substantially reduced ability to identify common environmental sounds in CI patients (45.3%). Except for vowels, all speech test scores significantly correlated with the environmental sound test scores: r = 0.73 for HINT in quiet, r = 0.69 for HINT in noise, r = 0.70 for CNC, r = 0.64 for consonants and r = 0.48 for vowels.

    This paper focuses on the mental patients in Arabo-Islamic Middle Ages. Patients suffering from mental illnesses generated a lot of interest for Arabo-Islamic physicians. The first objective of this study is to identify who were the mentally infirm and to compare the Arab physicians' typologies of mental patients to that of their Greek predecessors. The second part of this paper shifts the focus from theoretical descriptions to case histories and biographical sources, in order to understand how the physicians treated their mental patients, and to find out what was the social impact of this medical approach. Finally, because the special provision for the insane is a distinctive feature of the Islamic hospital, the third part of my paper examines whether the main purpose of these hospitals was the patients' confinement or their treatment.

    Background Fractures in older patients are common, morbid, and associated with increased risk of subsequent fractures. Inpatient and outpatient management and treatment of fractures can be costly. With more emphasis placed on quality care for Medicare beneficiaries, we studied if patients were receiving proper screening for osteoporosis and treatment after diagnosis of fracture. This study aims to determine if adequate screening and treatment for osteoporosis occurs in the postfracture period. Methods A retrospective analysis of Medicare beneficiaries aged 67 years or older was gathered from a single institution in both inpatient and outpatient visits. Based on International Classification of Diseases ninth revision codes, primary diagnosis of fractures of neck and trunk, upper limb, and lower limb were obtained in addition to current procedural terminology codes for fracture procedures. We studied patients who had been screened for osteoporosis with a bone mineral study or received osteoporosis treatment after their fracture. Results Medicare beneficiaries totaling 1,375 patients were determined to have an inclusion fracture between June 1, 2013 and November 30, 2014. At the time of our analysis on December 1, 2014, 1,219 patients were living and included in the analysis. Of these patients, 256 (21.0%) either received osteoporosis testing with bone mineral density or received treatment for osteoporosis. On sex breakdown, 208/820 (25.4%) females received proper evaluation or treatment of osteoporosis in comparison to 48/399 (12.0%) males. This is in comparison to the Centers for Medicare and Medicaid Services’ national average of 19.1% for osteoporosis management in females. Conclusion A minority of studied patients received evaluation or treatment for osteoporosis after their fracture. Postfracture investigation and treatment for osteoporosis in Medicare beneficiaries is inadequate. If improved, Medicare costs could be reduced by prevention of future fractures

    The purpose of this study was to assess the physiological strain experienced by North American electrical utility workers during the performance of their normal work duties in heat stressed conditions. Three common job categories were monitored as they are normally performed in 32 electrical utility workers: (i) Ground Work (n = 11); (ii) Bucket Work (n = 9); and (iii) Manual Pole Work (n = 12). Worker hydration status (urine specific gravity (USG)) was measured prior to and following the work monitoring period (duration: 187 ± 104 min). Core and skin temperatures as well as heart rate were measured continuously. Physiological Strain Index (PSI) was calculated from the measurements of core temperature and heart rate. Prior to the start of the work shift, 38% of workers were euhydrated (USG < 1.020; n = 12) whereas the majority of workers were dehydrated (USG > 1.020; prevalence: 75%; p < 0.01) following work. The overall mean and peak core temperatures for all monitored workers were 37.9 ± 0.3 °C and 38.3 ± 0.5 °C, respectively. When responses were compared between job categories, greater mean and peak increases in core temperature were observed in Manual Pole Work relative to the other job categories (both p < 0.04). In fact, six workers performing Manual Pole Work achieved core temperatures in excess of 38.5 °C, while only one other worker surpassed this threshold in Bucket Work. The high levels of thermal strain were paralleled by elevated mean and peak heart rate and PSI responses, which were greater in Manual Pole Work in comparison to the other job categories (all p ≤ 0.05). Furthermore, two workers performing Manual Pole Work achieved severely elevated core temperatures reaching or exceeding 39.5 °C along with prolonged periods of near maximal heart rate responses (i.e., >90% of heart rate reserve). We report elevated levels of thermal and cardiovascular strain in electrical utility workers during work in the heat and potentially dangerous levels of

    During the last 20 years, numerous studies have highlighted the need to consider Quality of Life (QoL) issues in the treatment of brain cancer. However, gaps in scientific knowledge are still present as we have poor data surrounding the whole experience in patients and regarding their needs. The present study was aimed at evaluating QoL in brain cancer patients and correlated aspects. In particular, we aimed to assess QoL, mood state, and emotional issues in order to describe the patients’ experience to find out the critical aspects involved. Methods We obtained data from 85 patients during chemotherapy treatment at the National Neurological Institute ‘C. Besta’ of Milan, Italy. We used standardised questionnaires to assess different aspects of patients’ QoL. In particular, the functional assessment of cancer therapy-brain (FACT-Br) and the Hamilton scale were used. We also performed a semi-structured ad hoc interview in order to collect ­narrative data about patients’ experience. Results Our data depict a difficult adjustment process to the illness, even though positive elements emerged. Indeed, patients reported a satisfying self-perceived QoL, although specific concerns are still present. Further, even if many patients report depressive symptoms, only a minority have a severe condition. Conclusion Brain cancer may heavily affect patients’ QoL and well being. However, some element of the context may improve the ­adjustment to the disease. In particular, we found that most patients found psychosocial resources to cope with cancer and that spiritual well being also seems to play a key role. These issues deserve further studies in order to obtain significant clinical recommendations. PMID:26635895

    Objective: Haemodialysis and peritoneal dialysis renal replacement treatment options are in clinical equipoise, although the cost of haemodialysis to the National Health Service is £16,411/patient/year greater than peritoneal dialysis. Treatment decision-making takes place during the pre-dialysis year when estimated glomerular filtration rate drops to between 15 and 30 mL/min/1.73 m2. Renal disease can be familial, and the majority of patients have considerable health service experience when they approach these treatment decisions. Factors affecting patient treatment decisions are currently unknown. The objective of this article is to explore data from a wider study in specific relation to the types of vicarious learning experiences reported by pre-dialysis patients. Methods: A qualitative study utilised unstructured interviews and grounded theory analysis during the participant’s pre-dialysis year. The interview cohort comprised 20 pre-dialysis participants between 24 and 80 years of age. Grounded theory design entailed thematic sampling and analysis, scrutinised by secondary coding and checked with participants. Participants were recruited from routine renal clinics at two local hospitals when their estimated glomerular filtration rate was between 15 and 30 mL/min/1.73 m2. Results: Vicarious learning that contributed to treatment decision-making fell into three main categories: planned vicarious leaning, unplanned vicarious learning and historical vicarious experiences. Conclusion: Exploration and acknowledgement of service users’ prior vicarious learning, by healthcare professionals, is important in understanding its potential influences on individuals’ treatment decision-making. This will enable healthcare professionals to challenge heuristic decisions based on limited information and to encourage analytic thought processes. PMID:26770780

    Osteopathy in the cranial field is an approach used by manual and physical therapists. However, there is minimal information in the literature about patient experiences of this treatment. The present study was undertaken to explore patients' experiences of osteopathy in the cranial field. Patients completed the Patient Perception Measure-Osteopathy in the Cranial Field and identified sensations they experienced during treatment. Additional measures of anxiety, depression, Satisfaction With Life, and Meaningfulness of Daily Activity were completed. The Patient Perception Measure-Osteopathy in the Cranial Field was internally consistent (Cronbach's α = .85). The most frequently experienced sensations of osteopathy in the cranial field patients were "relaxed," "releasing," and "unwinding." Satisfaction With Life and Meaningfulness of Daily Activity were positively associated with Patient Perception Measure-Osteopathy in the Cranial Field scores. Negative associations were observed between the Patient Perception Measure-Osteopathy in the Cranial Field and depression. Psychometric properties of the Patient Perception Measure-Osteopathy in the Cranial Field require further testing. The observed associations of Satisfaction With Life and depression with patients' perceptions of osteopathy in the cranial field treatment needs to be tested in larger clinical manual therapy cohorts.

    Tipranavir, a non-peptidic protease inhibitor which shows in vitro efficacy against some HIV-1-resistant strains, can be used in salvage therapies for multi-experienced HIV patients due to its peculiar resistance profile including 21 mutations at 16 protease positions according to International AIDS Society (IAS). Other genotypic scores, however, which attribute a different weight to single amino-acid substitutions, have been recently proposed. To validate the clinical utility of four different genotypic scores for selecting tipranavir responders, the baseline resistance pattern of 176 HIV heavily experienced patients was correlated with virological success (HIV-RNA<50 copies/ml) after 24 weeks of a new treatment based on tipranavir/ritonavir. Virological suppression after 24 weeks was reached by 42.5% of patients. With univariate analysis, genotypic scores were all associated with outcome but showed a low accuracy with ROC analysis, with the weighted score (WS) by Scherer et al. demonstrating the best performance with an AUC of 68%. Only 52% of patients classified as susceptible (WS< or =3) responded to the new therapy. The following variables were significantly associated (p<0.05) to failure with multivariate analysis: WS, log peak of HIV-RNA, IAS mutations: L33F, I54AMV, Q58E, and non-IAS mutation: N37DES. On the contrary, the use of T20 in T20-naïve patients and the V82AFSI and F53LY non-IAS mutations were associated with virological success. The study suggests that even if the "weighted" scores are able to interpret correctly the antiretroviral resistance profile of multi-experienced patients, it is difficult to individuate a cut-off which can be easily applied to this population for discriminating responders.

    Background and Aim. This is an open label prospective cohort study conducted at a tertiary care hospital. The primary endpoint is SVR12 in patients treated with sofosbuvir-based therapy in post-liver transplant patients with genotype 4 HCV recurrence. Methodology. Thirty-six treatment-experienced liver transplant patients with HCV recurrence received sofosbuvir and ribavirin ± peginterferon. Results. We report here safety and efficacy data on 36 patients who completed the follow-up period. Mean age was 56 years, and the cohort included 24 males and one patient had cirrhosis. Mean baseline HCV RNA was 6.2 log10 IU/mL. The majority of patients had ≥ stage 2 fibrosis. Twenty-eight patients were treated with pegylated interferon plus ribavirin in addition to sofosbuvir for 12 weeks and the remaining were treated with sofosbuvir plus ribavirin only for 24 weeks. By week 4, only four (11.1%) patients had detectable HCV RNA. Of the 36 patients, 2 (5.5%) relapsed and one died (2.75%). Conclusion. Our results suggest that sofosbuvir + ribavirin ± pegylated interferon can be utilized successfully to treat liver transplant patients with HCV recurrence. PMID:27446833

  1. Clock time and embodied time experienced by patients with inoperable lung cancer.

    2010-01-01

    In this study, we explore how patients with inoperable lung cancer (LC) discuss their experiences of time, based on content analysis of open interviews with 35 patients 1 year after diagnosis, using Davies' distinction between "clock time" and "embodied time" as sensitizing concepts. Two interrelated themes were derived: (1) aspects related to the healthcare system, with 3 subthemes: waiting times in the healthcare system, limited time for patient-professional contact, and limited time for coordination of services, and (2) existential aspects, with subthemes: the future with LC and managing an uncertain and finite life with LC. Time could be experienced as problematic for these patients, when limited or lacking or through long periods of waiting, especially when these periods occurred without adequate preparation or information. This contributed to exacerbation of these patients' existing sense of uncertainty, their perception of care as impersonal and insecure, and their need to remain alert and act on their own behalf. Awareness of the seriousness of their disease and the prospect of a limited lifetime was described as increasing uncertainty about dying and fear of certain death. People also described efforts to constructively deal with their situation by reprioritizing their remaining time, having increased appreciation of some aspects of daily life, and living consciously in the present. This analysis suggests a collision between clock time, which steers the healthcare system, and embodied time, as experienced by individuals. Greater attention to psychosocial needs is suggested as one means of positively affecting patients' experiences of time and uncertainty. PMID:19926976

    Background After treatment cessation, a high prevalence of relapse was reported in chronic hepatitis B (CHB) patients in China, especially in nucleot(s)ide analogues (NUCs)-experienced patients. Re-treatment for these patients remains unsolved. Objectives This study aims to evaluate the efficacy of PEGylated interferon in HBeAg positive patients with exposure to antiviral therapy. Patients and Methods A total of 55 treatment-experienced, HBeAg positive Chinese patients were enrolled in this study. Of these patients, 33 were NUCs-experienced and 22 were interferon-experienced. PEGylated interferon was administered to 34 patients; and 21 patients were retreated with conventional interferon. Results Of the 34 treatment-experienced patients who received PEGylated interferon, 52.9% achieved virologic response, and 41.2% achieved HBeAg loss and seroconversion. Patients who were treated with PEGylated interferon for 48 weeks achieved higher virologic response (80%); HBeAg loss (60%); HBeAg seroconversion (60%); and HBsAg loss (5%) than patients treated for 24 weeks with PEGylated interferon. Their responses were also higher than those who were treated with conventional interferon. HBeAg seroconversion in treatment-experienced patients was independently associated with 48-week PEGylated interferon therapy duration. Conclusions PEGylated interferon was effective in treatment-experienced patients with HBeAg positive CHB, and showed higher rates of virological response, HBeAg loss, and seroconversion. The results provide important information regarding the role of re-treatment with PEGylated interferon in treatment-experienced HBeAg positive patients. PMID:27257427

    Chronic obstructive pulmonary disease (COPD) is a complex and heterogeneous condition characterized by occasional exacerbations. Identifying clinical subtypes among patients experiencing COPD exacerbations (ECOPD) could help better understand the pathophysiologic mechanisms involved in exacerbations, establish different strategies of treatment, and improve the process of care and patient prognosis. The objective of this study was to identify subtypes of ECOPD patients attending emergency departments using clinical variables and to validate the results using several outcomes. We evaluated data collected as part of the IRYSS-COPD prospective cohort study conducted in 16 hospitals in Spain. Variables collected from ECOPD patients attending one of the emergency departments included arterial blood gases, presence of comorbidities, previous COPD treatment, baseline severity of COPD, and previous hospitalizations for ECOPD. Patient subtypes were identified by combining results from multiple correspondence analysis and cluster analysis. Results were validated using key outcomes of ECOPD evolution. Four ECOPD subtypes were identified based on the severity of the current exacerbation and general health status (largely a function of comorbidities): subtype A (n = 934), neither high comorbidity nor severe exacerbation; subtype B (n = 682), moderate comorbidities; subtype C (n = 562), severe comorbidities related to mortality; and subtype D (n = 309), very severe process of exacerbation, significantly related to mortality and admission to an intensive care unit. Subtype D experienced the highest rate of mortality, admission to an intensive care unit and need for noninvasive mechanical ventilation, followed by subtype C. Subtypes A and B were primarily related to other serious complications. Hospitalization rate was more than 50% for all the subtypes, although significantly higher for subtypes C and D than for subtypes A and B. These results could help identify characteristics

Twenty-four residents and twelve nurses from four nursing homes participated in an action research study. The use of lavender augustofolia essential oil diffused nightly was perceived as an effective care modality reducing insomnia and anxiety in this patient cohort. Nurses experienced some negative attitudes among colleagues because they considered aromatherapy as not evidence based. Nurses require greater access to evidence based use of Aromatherapy. Further research is needed to study how smell can enhance dementia care. PMID:24199975

    A phenomenon characterized by the experience of seeing light without any light actually entering the eye is called phosphenes or photopsias. Phosphenes can occur spontaneously or via induction by external stimuli. Previous reports regarding phosphenes have primarily focused on externally induced phosphenes such as by applying alternating or direct current to the cortex. A few of these reports used functional magnetic resonance (fMRI) to study activations induced by cortical phosphenes. However, there are no fMRI reports on spontaneous phosphenes originating from the retina and the resulting pattern of cortical activations. We performed fMRI during a reversing checkerboard paradigm in three LCA patients who underwent unilateral gene therapy and reported experiencing frequent phosphene on a daily basis. We observed bilateral cortical activation covering the entire visual cortices when patients reported experiencing phosphenes. In contrast, in the absence of phosphenes, activation was regulated by patient's visual ability and demonstrated improved cortical activation due to gene therapy. These fMRI results illustrate the potential impact of phosphene perception on visual function and they may explain some of the variability that clinicians find in visual function testing in retinal degeneration. Although we did not perform correlations between visual function and phosphenes, we hope data presented here raises awareness of this phenomenon and its potential effect on visual function and the implications for clinical testing. We recommend a thorough history for phosphene experiences be taken in patients with retinal disease who are candidates for gene or molecular therapy. Lastly, these data illustrate the potential power of fMRI as an outcome measure of gene therapy and the negative impact phosphenes may have on vision testing. fMRI has proven to be a sensitive, non-invasive, and reproducible test paradigm for these purposes and can complement standard visual function

    The Tidal Model has been implemented in Rangipapa, a regional secure mental health forensic unit in New Zealand. A phenomenological study was undertaken to obtain reflective description of the nursing care experience from the perspective's of four Registered Nurses and four Special Patients. Five major themes were identified that appeared to capture the experiences of the participants. The themes show changes to the unit's unique culture and values following implementation of the model. These changes engendered a sense of hope, where nurses felt they were making a difference and patients were able to communicate in their own words their feelings of hope and optimism. Levelling was experienced as an effect emerging from individual and group processes whereby a shift in power enhanced a sense of self and connectedness in their relationships. These interpersonal transactions were noted by the special patients as being positive for their recovery. This enabled effective nurse-patient collaboration expressed simply as working together. The participants reported a feeling of humanity, so that there was a human face to a potentially objectifying forensic setting. Implications arising from this study are that the use of the model enables a synergistic interpersonal process wherein nurses are professionally satisfied and patients are validated in their experience supporting their recovery.

    Resistance to antiretroviral agents is a significant concern in the clinical management of HIV-infected individuals, particularly in areas of the world where treatment options are limited. In this study, we aimed to identify HIV drug-resistance-associated mutations in 40 drug-naïve patients and 62 patients under antiretroviral therapy (ART) referred to the Shiraz HIV/AIDS Research Center - the first such data available for the south of Iran. HIV reverse transcriptase and protease genes were amplified and sequenced to determine subtypes and antiretroviral- resistance-associated mutations (RAMs). Subtype CRF35-AD recombinant was the most prevalent in all patients (98 of 102, 96 %), followed by subtype A1, and subtype B (one each, 2 %). Among the 40 ART-naïve patients, two mutations associated with nucleoside reverse transcriptase inhibitor (NRTI) resistance (two with Y115F and T215I) and three associated with non-nucleoside reverse transcriptase inhibitor (NNRTI) resistance (two with G190S and Y181C, four with V179T) were found. Among ART-experienced patients, four mutations associated with resistance to NRTI, four with NNRTI, and five with protease inhibitors (PI) were found. Twenty patients with high levels of resistance were already on second-line therapy. We document for the first time in this region of Iran high levels of ART resistance to multiple drugs. Our findings call for more vigilant systematic ART resistance surveillance, increased resistance testing, careful management of patients with existing regimens, and strong advocacy for expansion of available drugs in Iran.

    Objective: This study aims to examine Gender Difference in the level of Discrimination and Stigma experienced by people diagnosed with Major Depressive Disorder in Pakistan. It was hypothesized that Women diagnosed with Depression are likely to be experiencing more Discrimination and Internalized Stigma in comparison to Men. Methods: This is a Cross Sectional Study. Thirty eight patients diagnosed with Major Depressive Disorder recruited from different Government Sector Hospitals of Lahore; were approached after obtaining informed consent. Discrimination and Stigma were measured through Discrimination and Stigma Scale and Internalized Stigma of Mental Illness Inventory respectively. Results: Both Men and Women experience considerably high level of associated Stigma and Discrimination due to their Mental Illness. However, Women in comparison to Men experience significantly greater level of Internalized Stigma especially in domains of Discrimination Experience and Social Withdrawal. Conclusion: The findings of this study highlight the fact that people with Depression can be more benefited with psychological treatment if dealing with Stigma and Discrimination is also addressed in Intervention Plans.

    Crohn disease and ulcerative colitis, collectively known as inflammatory bowel disease (IBD), are chronic and have a fluctuating clinical course that impacts daily life. Daily life with a chronic disease involves thinking and worrying about the limitations that chronic disease causes. Knowledge about how patients who suffer from IBD manage critical incidents in daily life is lacking. The aim of the study was to describe how patients living with IBD experience critical incidents in daily life in relation to their disease and symptoms. Thirty adult patients were interviewed focusing on critical incidents in daily life. Data were analyzed using the critical incident technique. The study comprised 224 critical incidents and was grouped into 21 subcategories and 5 categories: losing bowel control, having a body that smells, being unable to meet own and others' expectations, not being believed or seen, and experiencing frustration due to side effects and ineffective treatment. These categories formed one main area describing the overall result “The bowels rule life.” The uncertain nature of IBD created critical incidents in which the bowel ruled life, causing patients to avoid social interaction. It also placed considerable demands on the family and sometimes had a negative effect on the afflicted person's career. PMID:26870902

    Dolutegravir is an HIV integrase inhibitor with a high genetic barrier to resistance and is active against raltegravir- and/or elvitegravir-resistant strains. The clinical development of dolutegravir for HIV infection rescue therapy is based on 3 clinical trials. In the SAILING trial, dolutegravir (5 mg once daily) in combination with 2 other antiretroviral agents was well tolerated and showed greater virological effect than raltegravir (400 mg twice daily) in the treatment of integrase inhibitor-naïve adults with virological failure infected with HIV strains with at least two-class drug resistance. The VIKING studies were designed to evaluate the efficacy of dolutegravir as rescue therapy in treatment-experienced patients infected with HIV strains with resistance mutations to raltegravir and/or elvitegravir. VIKING-1-2 was a dose-ranging phase IIb trial. VIKING-3 was a phase III trial in which dolutegravir (50 mg twice daily) formed part of an optimized regimen and proved safe and effective in this difficult-to-treat group of patients. Dolutegravir is the integrase inhibitor of choice for rescue therapy in multiresistant HIV infection, both in integrase inhibitor-naïve patients and in those previously treated with raltegravir or elvitegravir.

    Different sort of people are interested in personal identity. Philosophers frequently ask what it takes to remain oneself. Caregivers imagine their patients' experience. But both philosophers and caregivers think from the armchair: they can only make assumptions about what it would be like to wake up with massive bodily changes. Patients with a locked-in syndrome (LIS) suffer a full body paralysis without cognitive impairment. They can tell us what it is like. Forty-four chronic LIS patients and 20 age-matched healthy medical professionals answered a 15-items questionnaire targeting: (A) global evaluation of identity, (B) body representation and (C) experienced meaning in life. In patients, self-reported identity was correlated with B and C. Patients differed with controls in C. These results suggest that the paralyzed body remains a strong component of patients' experienced identity, that patients can adjust to objectives changes perceived as meaningful and that caregivers fail in predicting patients' experience.

    Although fatigue is a common symptom in neuromuscular disorders, little is known about different types of fatigue. Sixty-five FSHD, 79 adult-onset MD and 73 HMSN type I patients were studied. Experienced fatigue was assessed with the CIS-fatigue subscale. Physiological fatigue was measured during a 2-min sustained maximal voluntary contraction of the biceps brachii muscle using the twitch interpolation technique to assess central activation failure (CAF) and peripheral fatigue. Experienced fatigue, CAF and peripheral fatigue appeared to be predominantly separate types of fatigue. PMID:18690504

    2013-01-01

    Background A comprehensive model of the relationships among different shared decision-making related constructs and their effects on patient-relevant outcomes is largely missing. Objective of our study was the development of a model linking decision-making in medical encounters to an intermediate and a long-term endpoint. The following hypotheses were tested: physicians are more likely to involve patients who have a preference for participation and are willing to take responsibility in the medical decision-making process, increased patient involvement decreases decisional conflict, and lower decisional conflict favourably influences patient satisfaction with the physician. Methods This model was tested in a German primary care sample (N = 1,913). Psychometrically tested instruments were administered to assess the following: patients’ preference for being involved in medical decision-making, patients’ experienced involvement in medical decision-making, decisional conflict, and satisfaction with the primary care provider. Structural equation modelling was used to explore multiple associations. The model was tested and adjusted in a development sub-sample and cross-validated in a confirmatory sample. Demographic and clinical characteristics were accounted for as possible confounders. Results Local and global indexes suggested an acceptable fit between the theoretical model and the data. Increased patient involvement was strongly associated with decreased decisional conflict (standardised regression coefficient Β = −.73). Both high experienced involvement (Β = .34) and low decisional conflict (B = -.28) predicted higher satisfaction with the physician. Patients’ preference for involvement was negatively associated with the experienced involvement (B = −.24). Conclusion Altogether, our model could be largely corroborated by the collected empirical data except the unexpected negative association between preference for involvement and

    Purpose. Whistleblowing is the reporting of illegal, immoral, or illegitimate practices to persons or organizations that may affect the action. The current study compares experienced nurses to nursing students regarding their willingness to blow the whistle to protect a patient's interests. Methods. 165 participants were divided into two groups: 82 undergraduate nursing students and 83 experienced nurses. Participants responded to two vignettes that described a colleague's and a manager's misconduct at work. Results. The nursing students perceived the severity of the misconduct significantly lower compared to the experienced nurses. The nursing students also ranked the internal and external whistleblowing indices higher than the nurses, but the differences did not reach statistical significance. For each of the examined internal and external indices, professional experience was found to be significant in multivariate regression analyses. Conclusions. Even though nursing students perceived the severity of the misconduct significantly lower than the experienced nurses, the students demonstrated a greater readiness to blow the whistle, both internally and externally. Recommendations for handling comparable situations are offered. PMID:25379527

    Background Understanding the emergence and spread of multidrug-resistant tuberculosis (MDR-TB) is crucial for its control. MDR-TB in previously treated patients is generally attributed to the selection of drug resistant mutants during inadequate therapy rather than transmission of a resistant strain. Traditional genotyping methods are not sufficient to distinguish strains in populations with a high burden of tuberculosis and it has previously been difficult to assess the degree of transmission in these settings. We have used whole genome analysis to investigate M. tuberculosis strains isolated from treatment experienced patients with MDR-TB in Uganda over a period of four years. Methods and Findings We used high throughput genome sequencing technology to investigate small polymorphisms and large deletions in 51 Mycobacterium tuberculosis samples from 41 treatment-experienced TB patients attending a TB referral and treatment clinic in Kampala. This was a convenience sample representing 69% of MDR-TB cases identified over the four year period. Low polymorphism was observed in longitudinal samples from individual patients (2-15 SNPs). Clusters of samples with less than 50 SNPs variation were examined. Three clusters comprising a total of 8 patients were found with almost identical genetic profiles, including mutations predictive for resistance to rifampicin and isoniazid, suggesting transmission of MDR-TB. Two patients with previous drug susceptible disease were found to have acquired MDR strains, one of which shared its genotype with an isolate from another patient in the cohort. Conclusions Whole genome sequence analysis identified MDR-TB strains that were shared by more than one patient. The transmission of multidrug-resistant disease in this cohort of retreatment patients emphasises the importance of early detection and need for infection control. Consideration should be given to rapid testing for drug resistance in patients undergoing treatment to monitor the

    Multiple sclerosis (MS) can result in significant changes in psychological functioning. Depression and cognitive deficits are commonly present. In addition personality changes have been described. A growing body of research is showing negative impact of psychological stress on disease course. Our study focused on the profile of depression, capacity for coping with stress and experienced distress in patients with MS measured by a performance based method for personality assessment-the Rorschach Inkblot Method (RIM). We included 95 patients with MS and 44 healthy controls. RIM was used with all participants and was scored by the Exner Comprehensive system. Compared to healthy controls MS patients had statistically significantly lower capacity for coping with stress, complexity of information processing, body image, willingness to process emotional stimulation and interpersonal interest. Surprisingly patients had lower experienced distress than controls. We propose that the profile of depression in advanced MS disease might be better described in terms of negative symptoms such as emotional withdrawal and apathy and less with the profile of positive symptoms such as rumination and worry. RIM variables were not significantly associated with the EDSS. Interventions from which patients could benefit are discussed. PMID:24321148

    Background Little research has been conducted regarding the role of pulvinar nuclei in the pathogenesis of visual hallucinations due to the difficulty of assessing abnormalities in this region using conventional magnetic resonance imaging (MRI). The present study aimed to retrospectively investigate the relative abilities of diffusion-weighted imaging (DWI), fluid-attenuated inversion recovery (FLAIR), and susceptibility-weighted imaging (SWI) to visualize the pulvinar and to ascertain the relationship between pulvinar visualization and visual hallucinations. Methods A retrospective analysis of 3T MRIs from 73 patients (31 males, 42 females; mean age 73.5 ± 12.7 years) of the Memory Clinic of Mie University Hospital was conducted. Correlations between pulvinar visualization and the following were analyzed: age, sex, education, hypertension, hyperlipidemia, diabetes mellitus, Mini-Mental State Examination score, Evans index, and visual hallucinations. Results DWI detected low-signal pulvinar areas in approximately half of the patients (52.1%). Participants with pulvinar visualization were significantly older, and the pulvinar was more frequently visualized in patients who had experienced visual hallucinations compared to those who had not. No significant association was observed between whole brain atrophy and pulvinar visualization. Conclusions The results of the present study indicate that diffusion-weighted 3T MRI is the most suitable method for the detection of pulvinar nuclei in patients with dementia experiencing visual hallucinations.

Irrespective of the degree to which patients felt they had been involved in the decision-making process and of the outcome of their particular treatment, patients who felt satisfied with the adequacy of information given were significantly more likely to feel happy with their level of participation in the overall process of decision-making (P < 0.001). As part of a strategy investigating patient priorities, patients were asked to rank a series of possible acute and late treatment-related morbidities. Counter-intuitively, the majority of long-term survivors felt early short-term side-effects were more, or equally, as important as late morbidity with respect to influencing choice of therapy. Unpredictable importance was placed by patients on side-effects such as weight gain and fatigue in relation to other complications such as infertility and risk of relapse. Patients do not necessarily share doctors' priorities in decision-making or place the same emphasis on different types of morbidity. Experienced surrogates may assist us in understanding patients' perspectives and priorities. PMID:8546910

    BACKGROUND: Over the last two decades, the need for a longer-term perspective to stroke management has become increasingly recognised. This paper reports a component of a larger project aimed at developing a systematic, primary care-based service for stroke aftercare. AIM: To identify the types and prevalence of longer-term problems experienced by stroke patients and their carers in the United Kingdom (UK). METHOD: Systematically identified quantitative surveys reporting the prevalence of long-term stroke-related problems were reviewed and the findings extracted and interpreted against a patient and carer defined classification system, identified during an earlier review of the qualitative stroke literature. RESULTS: Twenty-seven UK surveys, including approximately 6000 patients and 3000 carers, and two literature reviews were identified by the search methods. Most of the problem areas identified in the qualitative stroke literature review were reported in the quantitative surveys and an additional two problems were identified (falls and sexual problems). The prevalence of problems in each of the areas was as follows: 19% to 62% for emotional problems; 18% to 46% for social problems; 13% to 77% for service issues; 18% to 88% for poor communication; 33% to 100% for transfer of care; and 10% to 73% for other areas. CONCLUSION: This review confirms the findings and recommendations from earlier work about the need for a longer-term holistic approach to the rehabilitation of stroke patients and support for carers. Having established the nature and frequency of the main problems experienced by stroke patients and their carers, the appropriate evidence-based interventions need to be identified and consolidated into a stroke service, facilitated by a robust patient-assessment process.

    A 49-year-old female with a history of several neurosurgical and otolaryngologic procedures for occipital meningioma and cerebrospinal fluid leaks was diagnosed with pneumocephalus after a one hour flight on a domestic jet airliner. Despite multiple operations, the air appeared to enter the cranium through a weak portion of the skull base due to the low atmospheric pressure in the cabin. The intracranial air was absorbed with conservative management. The patient was recommended not to fly before a definite diagnostic work up and a sealing procedure for the cerebrospinal fluid leak site had been performed. Recent advances in aviation technology have enabled many people to travel by air, including individuals with medical conditions. Low cabin pressure is not dangerous to healthy individuals; however, practicing consultant neurosurgeons should understand the cabin environment and prepare high risk patients for safe air travel.

    In the patient described in this study, oral implants failed as a probable consequence of severe, polysomnographically confirmed sleep bruxism. As this patient had the wish to be re-implanted after this failure, we decided to try diminishing the frequency of bruxism and duration first. To that end, two management strategies were used. Their efficacy was evaluated polysomnographically, yielding a total of six overnight recordings. Of the selected management strategies, the administration of low doses of the dopamine D1/D2 receptor agonist pergolide finally resulted in a substantial and lasting reduction in the bruxism outcome measures under study. This result supports the previous suggestion that central neurochemicals like dopamine may be involved in the modulation of sleep bruxism. The case report also illustrates the importance of an extensive history taking (questionnaires as well as oral) and clinical examination of oral implant patients for the presence of severe bruxism before the implant procedure is started. In case of doubt, polysomnography may be considered to definitively confirm or rule out the presence of severe sleep bruxism. PMID:17441871

    Specific phobia is an excessive and irrational fear often triggered by a stressor. Among different types of phobias arising in medical settings, we could not find any case reported for exclusively antiseptic fluids without any medical-surgical intervention. The term "anesthesia awareness" (AA) signifies the specific surgical period of time when an individual, in spite of being under intended general anesthesia, remains aware of the sensory stimuli and the memories of which also remain available for his subsequent explicit recall in the future. According to the "American Society of Anesthesiologists Practice Advisory", it is explicit recall during general anesthesia. Its hallmark is the presence of awareness of the events going on during the surgical procedure while being under a general anesthesia. AA is a distressing condition with immediate and long-term consequences. In spite of an estimated prevalence of 0.1%-0.2% of all the surgeries, our knowledge about this condition is limited. The most commonly reported consequences of AA are acute painful flashbacks of surgical events along with the emotional turmoil and a sense of helplessness followed later by posttraumatic stress disorder. Here, we report a unique case of occurrence of "antiseptic-phobia" in a patient following the experience of anesthesia awareness during cleft palate repair surgery. PMID:23725824

    The elevated prevalence of neuropsychiatric symptoms and disorders among patients with multiple sclerosis (MS) is well recognized, as are potential neuropsychiatric side effects of treatment with corticosteroids. Both methylprednisolone (MP) and repository corticotropin injection (HP Acthar® gel) have demonstrated efficacy in reducing short-term disability after exacerbations of MS. Although historical data are limited, repository corticotropin injection has not generally been associated with detrimental neuropsychiatric effects. We describe six cases of patients with relapsing-remitting MS who had previously experienced detrimental mood changes with MP treatment. Some of these patients had previous histories of mood disorders or other neuropsychiatric symptoms prior to MS diagnosis. All six patients were subsequently treated with repository corticotropin injection for MS exacerbations and each demonstrated improvements in MS symptoms. This clinical experience suggests that repository corticotropin injection should be considered as an alternative for patients who do not tolerate corticosteroids or have difficulties associated with intravenous medication. Furthermore, the rate of neuropsychiatric side effects observed in these patients was low. These observations support repository corticotropin injection as a viable alternative for the treatment of acute exacerbations of MS, particularly in patients who have a history of neuropsychiatric disorders or symptoms either independently or in response to MP treatment. In reviewing both the published data and our own clinical experience regarding potential neuropsychiatric adverse events with treatment for MS exacerbations, we hope to stimulate further research into the potential efficacy and safety of repository corticotropin injection among patients with some form of neuropsychiatric complications that must be considered when establishing a treatment plan for MS.

    Background: Patients with psychotic disorders who experienced childhood trauma show more social dysfunction than patients without traumatic experiences. However, this may not hold for all patients with traumatic experiences. Little is known about the potential compensating role of Five-Factor Model personality traits within this group, despite their strong predictive value for social functioning and well-being in the general population. Methods: Our sample consisted of 195 patients with psychotic disorders (74% diagnosed with schizophrenia) and 132 controls. Cluster analyses were conducted to identify and validate distinct personality profiles. General linear model analyses were conducted to examine whether patients with different profiles differed in social functioning and quality of life (QoL), while controlling for possible confounders. Mediation models were tested to assess potential causal links. Results: In general, patients with higher levels of self-reported traumatic experiences (PT+) showed lower QoL and more social withdrawal compared with patients with lower traumatic experiences (PT−). Two clusters reflecting personality profiles were identified. PT+ with the first profile (lower neuroticism and higher extraversion, openness, agreeableness, and conscientiousness) presented higher levels of QoL and better social functioning in several areas, including less withdrawal, compared with both PT+ and PT− with the second profile. PT+ and PT− with the first personality profile did not differ in QoL and social functioning. Mediation analyses suggested that personality traits mediate the relation between traumatic experiences and QoL and social withdrawal. Conclusions: Our findings indicate that personality may “buffer” the impact of childhood traumatic experiences on functional outcome in patients with psychotic disorders. PMID:24771304

    Context As with care giving and rehabilitation in chronic illnesses, the concern with traumatic brain injury (TBI), particularly with diffuse axonal injury (DAI), is that the caregivers are so overwhelmingly involved in caring and rehabilitation of the victim that in the process they become traumatized themselves. This review intends to shed light on the hidden and silent trauma sustained by the caregivers of severe brain injury survivors. Motor vehicle accident (MVA) is the highest contributor of TBI or DAI. The essence of trauma is the infliction of pain and suffering and having to bear the pain (i.e. by the TBI survivor) and the burden of having to take care and manage and rehabilitate the TBI survivor (i.e. by the TBI caregiver). Moreover many caregivers are not trained for their care giving task, thus compounding the stress of care giving and rehabilitating patients. Most research on TBI including DAI, focus on the survivors and not on the caregivers. TBI injury and its effects and impacts remain the core question of most studies, which are largely based on the quantitative approach. Evidence Acquisition Qualitative research can better assess human sufferings such as in the case of DAI trauma. While quantitative research can measure many psychometric parameters to assess some aspects of trauma conditions, qualitative research is able to fully reveal the meaning, ramification and experience of TBI trauma. Both care giving and rehabilitation are overwhelmingly demanding; hence , they may complicate the caregivers’ stress. However, some positive outcomes also exist. Results Caregivers involved in caring and rehabilitation of TBI victims may become mentally traumatized. Posttraumatic recovery of the TBI survivor can enhance the entire family’s closeness and bonding as well as improve the mental status of the caregiver. Conclusions A long-term longitudinal study encompassing integrated research is needed to fully understand the traumatic experiences of

    Residual HIV viremia, defined by low levels of plasma HIV RNA with enhanced-sensitivity assays, may persist even in the presence of successful antiretroviral therapy, but little is known about its determinants. Our objective was to evaluate the rate and determinants of residual viremia in patients who show stable undetectable plasma HIV-1 RNA with conventional assays. Forty-four multidrug-experienced patients with undetectable levels of HIV RNA for at least 2 years under raltegravir-based regimens were evaluated. An ultrasensitive (2.5 copies/ml) real-time PCR method was used to quantify plasma HIV RNA. After 12 months of salvage treatment, 48.3% of the patients had residual viremia between 2.5 and 37 copies/ml. The proportion of patients with plasma HIV RNA below 2.5 copies/ml decreased from 51.7% at 12 months to 30.8% at 24 months. The presence of residual viremia was not associated with levels of viremia before starting raltegravir. Considering CD4 counts, hepatitis B or C virus (HBV or HCV) coinfection, or other demographic characteristics, for the time interval between HIV diagnosis and initiation of antiretroviral therapy, patients with a longer interval (>1 year) were significant less likely to have RNA levels below 2.5 copies/ml at 12 months compared to patients who started therapy within 1 year of HIV diagnosis (28.6% vs. 73.3%, p=0.027). Half of the patients showing undetectable HIV viremia with conventional assays had low-level viremia with ultrasensitive assays, with no predictive role of viroimmunological status at the start of the regimen. The potential influence of the interval between HIV diagnosis and initiation of treatment should be confirmed in subjects with a known date of seroconversion. PMID:25092266

    Purpose Patients with a bipolar I disorder (BD-I) manic episode meeting the Diagnostic and Statistical Manual of Mental Disorders, fifth edition (DSM-5), criteria for “with mixed features” have a high incidence of suicide attempts and of anxiety, irritability, and agitation (AIA) symptoms. The aim of this analysis was to explore the relationship between suicidality and AIA symptoms in patients with BD-I experiencing mania with depressive symptoms, using data from a previous naturalistic study. Patients and methods Psychiatrists completed an online questionnaire about their adult patients who had a current BD-I manic episode. Questions covered the DSM-5 “with mixed features” specifier, the severity of AIA symptoms, the frequency and controllability of suicidal ideation, and the number of suicide attempts. Results Of 1,035 patients with BD-I mania who were included in the analyses, 348 (33.6%) met the criteria for the DSM-5 “with mixed features” specifier (three or more depressive symptoms). These patients were further stratified according to the severity of their AIA symptoms: “mild AIA” (zero or one AIA symptom above a severity threshold; 105 patients) or “severe AIA” (all three AIA symptoms above a severity threshold; 167 patients). A greater incidence of suicidal ideation was observed in the severe AIA group (71.9%) than in the mild AIA group (47.6%). Twice as many patients had easily controlled suicidal ideation than difficult-to-control suicidal ideation in both subgroups. The mean number of suicide attempts was higher in the severe AIA group than in the mild AIA group, during the current episode (0.84 vs 0.34 attempts, respectively; P<0.05) and over the patient’s lifetime (1.56 vs 1.04 attempts, respectively). Conclusion The high risk of suicide among BD-I mania patients with depressive symptoms is further increased when they experience severe AIA symptoms. Recognizing AIA symptoms in BD-I mania could provide a means of identifying

    The early integration of specialist palliative care has been shown to benefit the quality of life of patients with advanced cancer. In order to explore whether other seriously ill people and people at even earlier phases would also benefit from early palliative care, we conducted 18 qualitative interviews with people having cancer, chronic obstructive lung disease, heart failure, or dementia at different phases of the illness trajectory about how they experienced care needs related to their disease from diagnosis onward. Respondents experienced needs within the different domains of palliative care at different stages of the illness and different illness types or duration of the illness. This study contributes to the understanding of primary care needs of patients for whom palliative care (not necessarily specialized palliative care) could be beneficial. PMID:25852203

    2012-01-01

    Background Even though the use of perioperative checklists have resulted in significant reduction in postoperative mortality and morbidity, as well as improvements of important information communication, the utilization of checklists seems to vary, and perceived barriers are likely to influence compliance. In this grounded theory study we aimed to explore the challenges and strategies of performing the WHO’s Safe Surgical Checklist as experienced by the nurses appointed as checklist coordinators. Methods Grounded theory was used in gathering and analyzing data from observations of the checklist used in the operating room, in conjunction with single and focus group interviews. A purposeful sample of 14 nurse-anesthetists and operating room nurses as surgical team members in a tertiary teaching hospital participated in the study. Results The nurses’ main concern regarding checklist utilization was identified as “how to obtain professional and social acceptance within the team”. The emergent grounded theory of “adjusting team involvement” consisted of three strategies; distancing, moderating and engaging team involvement. The use of these strategies explains how they resolved their challenges. Each strategy had corresponding conditions and consequences, determining checklist compliance, and how the checklist was used. Conclusion Even though nurses seem to have a loyal attitude towards the WHO’s checklist regarding their task work, they adjusted their surgical team involvement according to practical, social and professional conditions in their work environment. This might have resulted in the incomplete use of the checklist and therefore a low compliance rate. Findings also emphasized the importance of: a) management support when implementing WHO’s Safe Surgical Checklist, and b) interprofessional education approach to local adaptation of the checklists use.

    2014-01-01

    Given the increasing popularity of a hospice inpatient/residential facility (HIRF) among hospice patients and their family members, examining who uses HIRFs has been of increasing importance. Using the 2007 National Home and Hospice Care Survey (NHHCS), we found that about 14% of hospice patients received care in a HIRF in 2007. Characteristics of patients associated with HIRF use largely match the industry norm for a general inpatient level of care, and include: having no caregiver, or having an incapable caregiver; having imminent death; and being directly admitted to a hospice after discharge from a hospital. Given a recent stricter enforcement of reimbursement rules, however, we call for close monitoring of any change in the number of HIRF beds—particularly in rural and low-income urban areas.

    Differences in healthcare utilization and costs were examined in chronic myeloid leukemia (CML) patients experiencing first-, second- and third-line tyrosine kinase inhibitor (TKI) therapy. Three CML cohorts were identified from the Truven Health MarketScan® database: No-Switch Cohort (NSc) = did not switch from first-line; One-Switch Cohort (OSc) = switched from first- to second-line only; Two-Switch Cohort (TSc) = switched to second- and then third-line. A total of 3510 patients were identified (mean = 54%; age = 55.8 years). NSc comprised 81% of the sample, OSc comprised 15% and 4% were in the TSc. First-line utilization/costs were significantly higher in the OSc/TSc compared to the NSc. Second-line hospital/outpatient visits and costs were higher in TSc compared to OSc. TSc experienced a significant cost increase from first- to second-line ($4226.46), twice that of OSc ($2488.03). TKI switching is associated with a substantial increase in healthcare utilization and costs, particularly for patients who switch twice.

  3. A patient who experienced thyroid storm complicated by rhabdomyolysis, deep vein thrombosis, and a silent pulmonary embolism: a case report

    2013-01-01

    Background Thyroid storm is a serious condition of thyrotoxicosis. Hyperthyroidism often presents with thrombotic events, especially at cerebral sites; however, the possible association between a lower extremity deep vein thrombosis (LEDVT) and thyroid storm has not been previously reported. We encountered a patient who developed thyroid storm, associated with rhabdomyolysis, followed by LEDVT and a small silent pulmonary embolism (PE). The case is discussed with references to the pertinent literature. Case presentation A 50-year-old woman with no past medical history was referred to our hospital because of severe diarrhea, muscle weakness in her lower limbs (manual muscle testing: MMT 3), and disturbances of consciousness. She was diagnosed as having Graves’ disease based on the presence of struma, exophthalmos, and hyperthyroidism with TSH receptor antibody positivity; we further determined that the patient was experiencing thyroid storm based on the results of the Burch-Wartofsky scoring system and a Japanese diagnostic criteria. Treatment with steroids, iodine potassium, methimazole, and propranolol was initiated. Severe watery diarrhea continued, and the laboratory data revealed hypokalemia (2.0 meq/L). On day 14, a blood analysis showed a sudden elevation in her creatinine kinase (CK) level, leading to a diagnosis of rhabdomyolysis. Thereafter, the muscle weakness in her lower limbs advanced to a degree of MMT 1. Seven days after the diagnosis of rhabdomyolysis, pitting edema began to appear in bilateral lower extremities. Contrast-enhanced CT scans revealed a LEDVT involving the left common iliac vein, bilateral femoral veins, and left popliteal vein. Furthermore, a small PE was identified. Hyperthyroidism often presents with thrombotic events, especially at cerebral sites, but few reports of PE or LEDVT have been made. Conclusion This case suggests that the occurrence of thyroid storm may be associated with a risk of LEDVT and/or PE. We suggest that DVT

    Patient registries are essential tools for public health surveillance and research inquiry, and are a particularly important resource for understanding rare diseases. Registries provide consistent data for defined populations and can support the study of the distribution and determinants of various diseases. One advantage of registries is the ability to observe caseload and population characteristics over time, which might facilitate the evaluation of disease incidence, disease etiology, planning, operation and evaluation of services, evaluation of treatment patterns, and diagnostic classification. Any registry program must collect high quality data to be useful for its stated purpose. Registries can be developed for many different needs, and caution should be taken in interpreting registry data, which has inherent biases. We describe the methodological issues, limitations, and ideal features of registries to support various rare disease purposes. The future impact of registries on our understanding and interventions for rare diseases will depend upon technological and political solutions for global cooperation to achieve consistent data (via standards) and regulations for various registry applications.

    Data from 20 highly drug-experienced HIV-infected patients receiving tenofovir plus didanosine as part of a salvage regimen were analysed. At baseline, all but one patient harboured a virus bearing at least one nucleoside excision mutation (NEM); in 13 cases (65%) three or more NEM were detectable. After a median of 26 weeks of treatment, two patients (10%) selected the 65R mutation. These results support the hypothesis that NEM hinder the selection of this mutation.

    Several randomized trials and decision analysis models have found that remote monitoring may reduce health care utilization and expenditures in patients with cardiac implantable electronic devices (CIEDs), compared with in-office monitoring. However, little is known about the generalizability of these findings to unselected populations in clinical practice. To compare health care utilization and expenditures associated with remote monitoring and in-office monitoring in patients with CIEDs, we used Truven Health MarketScan Commercial Claims and Medicare Supplemental Databases. We selected patients newly implanted with an implantable cardioverter defibrillators (ICD), cardiac resynchronization therapy defibrillator (CRT-D), or permanent pacemaker (PPM), in 2009, who had continuous health plan enrollment 2 years after implantation. Generalized linear models and propensity score matching were used to adjust for confounders and estimate differences in health care utilization and expenditures in patients with remote or in-office monitoring. We identified 1,127; 427; and 1,295 pairs of patients with a similar propensity for receiving an ICD, CRT-D, or PPM, respectively. Remotely monitored patients with ICDs experienced fewer emergency department visits resulting in discharge (p = 0.050). Remote monitoring was associated with lower health care expenditures in office visits among patients with PPMs (p = 0.025) and CRT-Ds (p = 0.006) and lower total inpatient and outpatient expenditures in patients with ICDs (p <0.0001). In conclusion, remote monitoring of patients with CIEDs may be associated with reductions in health care utilization and expenditures compared with exclusive in-office care.

    Resistance to antiretroviral therapy (ART) threatens the success of programs to reduce HIV morbidity and mortality, particularly in countries with few treatment options. In the present study, genotype and phenotype data from ART-naïve and experienced hospitalized patients infected with HIV in Tehran, Iran were used to assess the prevalence and types of transmitted (TDR) and acquired drug resistance (ADR) mutations. All 30 participants naïve to ART and 62 of 70 (88.6%) participants receiving ART had detectable viral loads. Among participants receiving ART with sequencing data available (n = 62), 36 (58.1%) had at least one drug resistance mutation; the most common mutations were K103N (21.0%), M184V (19.4%), and the thymidine analogue mutations. Seven (11.3%), 27 (43.5%), and two (3.2%) of these participants had resistance to one, two, and three drug classes, respectively. High-level resistance to efavirenz (EFV) was more common among participants on EFV-based regimens than high-level lopinavir/ritonivar (LPV/r) resistance among those on LPV/r-based regimens (55.3% vs. 6.7%, P < 0.0001). Two (6.7%) antiretroviral-naïve participants had K103N mutations. These findings document an alarmingly high frequency of multiple HIV drug class resistance in Iran, confirm the presence of TDR, and highlight the need for systematic viral load monitoring and drug resistance testing, including at diagnosis. Expanded access to new antiretroviral medications from additional drug classes is needed.

    Background Successful scale-up in the use of malaria rapid diagnostic tests (RDTs) requires that patients accept testing and treatment based on RDT results and that healthcare providers treat according to test results. Patient-provider communication is a key component of quality care, and leads to improved patient satisfaction, higher adherence to treatment and better health outcomes. Voiced or perceived patient expectations are also known to influence treatment decision-making among healthcare providers. While there has been a growth in literature on provider practices around rapid testing for malaria, there has been little analysis of inter-personal communication around the testing process. We investigated how healthcare providers and patients interact and engage throughout the diagnostic and treatment process, and how the testing service is experienced by patients in practice. Methods This research was conducted alongside a larger study which explored determinants of provider treatment decision-making following negative RDT results in a rural district (Kibaale) in mid-western Uganda, ten months after RDT introduction. Fifty-five patients presenting with fever were observed during routine outpatient visits at 12 low-level public health facilities. Observation captured communication practices relating to test purpose, results, diagnosis and treatment. All observed patients or caregivers were immediately followed up with in-depth interview. Analysis followed the ‘framework’ approach. A summative approach was also used to analyse observation data. Results Providers failed to consistently communicate the reasons for carrying out the test, and particularly to RDT-negative patients, a diagnostic outcome or the meaning of test results, also leading to confusion over what the test can detect. Patients appeared to value testing, but were frustrated by the lack of communication on outcomes. RDT-negative patients were dissatisfied by the absence of information on an

    Background. An exploratory subanalysis of the ODIN trial was performed to evaluate the efficacy of darunavir/ritonavir (DRV/r) 800/100 mg OD versus 600/100 mg BID in patients who were NNRTI-experienced but PI-naïve. Methods. ODIN was a phase III, 48-week study comparing DRV/r OD versus BID in 590 treatment-experienced patients with no DRV resistance-associated mutations (RAMs) at screening. Patients received DRV/r 800/100 mg OD or DRV/r 600/100 mg BID plus ≥2 NRTIs. Of the 590 patients randomized, 272 (46%) were NNRTI-experienced but PI-naïve. Results. Overall, 272 patients received DRV/r OD (n = 135) or BID (n = 137) plus ≥2 optimised NRTIs. The mean age was 39 years; 35% were female; 27% were Black, 24% Caucasian, 26% Oriental/Asian, and 23% other races; 17% were recruited in South Africa; and 48% had non-B HIV-1 subtypes. Mean baseline plasma HIV-1 RNA load was 4.10 log10⁡ copies/mL; median CD4 cell count was 258 cells/μL. At week 48, 111/135 (82%) of DRV/r OD and 109/137 (80%) of DRV/r BID patients achieved an HIV-1 RNA load <50 copies/mL. No patient developed primary PI RAMs. Conclusion. DRV/r 800/100 mg OD in combination with ≥2 optimised NRTIs led to virological suppression <50 copies/mL in 82% of NNRTI-experienced, PI-naïve patients by week 48. PMID:26357568

    Providing patients with adequate information is an important component of care. This exploratory study investigated factors influencing patient satisfaction with and utilization of information booklets. The research was conducted in two stages. In stage 1, five commonly used cancer information booklets were reviewed by 36 Australian patients who were either receiving chemotherapy or had just completed treatment. Data were collected on patient satisfaction with, preference for and utilization of information booklets. In addition data were collected on variables identified in the literature as potentially influencing patient satisfaction, including patient characteristics, presentation and readability of booklets, and the timing of provision. A high level of satisfaction was found for all five information booklets, although a clear preference for one particular booklet emerged. The most notable feature of this booklet was its readability level (grade 8); in contrast the other booklets were written at levels equivalent to grades 11-12. Stage 2 focused on the side effects of patient information preference style on their satisfaction and recall of information presented in two booklets in the course of their treatment. No differences were found between patients who seek information and those who avoid it. The findings of this study suggest that patients' information needs may be better met if information booklets are written in plain English, and presented to patients prior to treatment. Future studies incorporating a larger sample of patients and greater selection and variety of information booklets are required to further determine if patient characteristics and features of booklet presentation influence patient satisfaction and preference.

    OBJECTIVE To examine the influence of utilization review and denial of specialty referrals on patient satisfaction with overall medical care, willingness to recommend one’s physician group to a friend, and desire to disenroll from the health plan. DESIGN Two cross-sectional questionnaires: one of physician groups and one of patient satisfaction. SETTING Eighty-eight capitated physician groups in California. PARTICIPANTS Participants were 11,710 patients enrolled in a large California network-model HMO in 1993 who received care in one of the 88 physician groups. MEASUREMENTS AND MAIN RESULTS Our main measures were how groups conducted utilization review for specialty referrals and tests, patient-reported denial of specialty referrals, and patient satisfaction with overall medical care. Patients in groups that required preauthorization for access to many types of specialists were significantly (p≤ .001) less satisfied than patients in groups that had few preauthorization requirements, even after adjusting for patient and other group characteristics. Patients who had wanted to see a specialist in the previous year but did not see one were significantly less satisfied than those who had wanted to see a specialist and actually saw one (p < .001). In addition, patients who did not see a specialist when desired were more likely to want to disenroll from the health plan than patients who saw the specialist (40% vs 18%, p≤ .001) and more likely not to recommend their group to a friend (38% vs 13%, p≤ .001). CONCLUSIONS Policies that limited direct access to specialists, and especially denial of patient-desired referrals, were associated with significantly lower patient satisfaction, increased desire to disenroll, and lower likelihood of recommending the group to a friend. Health plans and physician groups need to take these factors into account when designing strategies to reduce specialty care use. PMID:10337038

    This initiative utilized a collaborative learning approach to increase knowledge and experience in process improvement and systems thinking while targeting improved patient flow in seven radiology modalities. Teams showed improvements in their project metrics and collectively streamlined the flow for 530 patients per day by improving patient lead time, wait time, and first case on-time start rates. In a post-project survey of 50 project team members, 82% stated they had more effective solutions as a result of the process improvement methodology, 84% stated they will be able to utilize the process improvement tools again in the future, and 98% would recommend participating in another project to a colleague.

    The management and treatment of adult asthma has been associated with utilization of health services. Objectives: First, to investigate the likelihood of health service utilization, including primary care, emergency department, and hospital stays, among persons diagnosed with an asthma condition relative to those that do not have an asthma condition. Second, to examine the likelihood of poor physical health among asthma respondents relative to those that do not have an asthma condition. Third, to demonstrate that these relationships vary with frequency of utilization. Fourth, to discuss the magnitude of differences in frequent utilization between asthma and non-asthma respondents. Data Source: Data is derived from a random, stratified sampling of Hampton Roads adults, 18 years and older (n = 1678). Study Design: Study participants are interviewed to identify asthma diagnosis, access to primary care, frequency of emergency department utilization, hospital admissions, and days of poor physical health. Odds-ratios establish relationships with the covariates on the outcome variable. Findings: Those with asthma are found more likely (OR 1.50, 95% CI 1.05–2.15) to report poor physical health relative to non-asthma study participants. Further, asthma respondents are found more likely (OR 4.23, 95% CI 1.56–11.69) to frequently utilize primary care that may be associated with the management of the condition and are also more likely to utilize treatment services, such as the emergency department (OR 1.87, 95% CI 1.32–2.65) and hospitalization (OR 2.21, 95% CI 1.39–3.50), associated with acute and episodic care. Further, it is a novel finding that these likelihoods increase with frequency of utilization for emergency department visits and hospital stays. Conclusion: Continuity in care and better management of the diseases may result in less demand for emergency department services and hospitalization. Health care systems need to recognize that asthma patients are

    Among those decisions that may be made by a patient in response to an illness, the authors single out a certain class: contingent investment decisions. They are characterized by the patient's committing him- or herself, on the basis of prognostic counseling, to a certain action or non-action that he or she may regret in retrospect. Examples show that, when assessing utilities, the decision analyst runs a risk of handling such investment decisions incorrectly, unless they are made explicit and incorporated into the medical decision process. The anomaly is explained as a violation of the structural rules for decision trees and is also interpreted in terms of "the price of prognostic ignorance," a quantity closely related to the expected utility value of perfect information.

    Seven patients treated with continuous mechanical ventialtion were monitored with static and dynamic pressure-volume curves. Three patients developed no pulmonary complications, and mechanical ventilation was discontinued within 96 hr. In four patients, pressure-volume curves were used as a diagnostic aid in the detection of the physiologic defect resulting from bronchoconstriction, atelectasis, loculated pleural fluid, pulmonary edema, and mucous plugging. These measurements were also utilized to evaluate the effectivess of therapeutic modalities such as treatment of bronchoconstriction with bronchodilators, mucous plugging with adequate suctioning, and drainage of loculated pleural effusion. Pressure-v-lume measurements are simple, noninvasive, and require the smae equipment used in continuous mechanical ventilation. Pressure-volume monitoring of pediatric patients with curves warrants further investigation to evaluate its value.

    Introduction It is well established that sarcopenic patients are at higher risk of postoperative complications and short-term healthcare utilization. Less well understood is how these patients fare over the long-term after surviving the immediate postoperative period. We explored costs over the first postoperative year among sarcopenic patients. Methods We identified 1,279 patients in the Michigan Surgical Quality Collaborative database who underwent inpatient elective surgery at a single institution from 2006 to 2011. Sarcopenia, defined by gender-stratified tertiles of lean psoas area, was determined from preoperative CT scans using validated analytic morphomics. Data were analyzed to assess sarcopenia’s relationship to costs, readmissions, discharge location, intensive care unit admissions, hospital length of stay, and mortality. Multivariate models adjusted for patient demographics and surgical risk factors. Results Sarcopenia was independently associated with increased adjusted costs at 30, 90, and 180 but not 365 days. The difference in adjusted postsurgical costs between sarcopenic and non-sarcopenic patients was $16,455 at 30 days and $14,093 at one year. Sarcopenic patients were more likely to be discharged somewhere other than home (p <0.001). Sarcopenia was not an independent predictor of increased readmission rates in the postsurgical year. Conclusion The effects of sarcopenia on healthcare costs are concentrated in the immediate postoperative period. It may be appropriate to allocate additional resources to sarcopenic patients in the perioperative setting to reduce the incidence of negative postoperative outcomes. PMID:25990695

    Hemophilia is a serious rare disease that requires continuous management and treatment for which the medicine is costly at the annual average of 100 million KRW for an individual. The aim of this study was to investigate trends in the utilization of coagulation factor (CF) used for hemophilia treatment using the National Health Insurance database from 2010 to 2013 in Korea and compare the utilization of CF with other countries. The consumption of CF per capita (IU) in Korea was not more than other countries with similar income to Korea. However, CF usage per patient IU was higher because the prevalence rate of hemophilia in Korea was lower than in other countries while the number of serious patients was much more. Therefore, it is difficult to say that the consumption of hemophilia medicine in Korea is higher than that in other countries. The consumption and cost of hemophilia medicine in Korea is likely to increase due to the increased utilization of expensive bypassing agents and the widespread use of prophylaxis for severe hemophilia. Even during the research period, it increased slightly and other countries show a similar trend. Thus, hemophilia patient management should accompany active monitoring on the health and cost outcomes of pharmaceutical treatment in the future. This study is expected to contribute to further insight into drug policies for other countries that face similar challenges with high price pharmaceuticals.

    Background Acute coronary syndromes (ACS) have been associated with lower health utilities (HUs) compared with the general population. Given the prognostic improvements after ACS with the implementation of coronary angiography (eg, percutaneous coronary intervention (PCI)), contemporary HU values derived from patient-reported outcomes are needed. Methods We analysed data of 1882 patients with ACS 1 year after coronary angiography in a Swiss prospective cohort. We used the EuroQol five-dimensional questionnaire (EQ-5D) and visual analogue scale (VAS) to derive HU indexes. We estimated the effects of clinical factors on HU using a linear regression model and compared the observed HU with the average values of individuals of the same sex and age in the general population. Results Mean EQ-5D HU 1-year after coronary angiography for ACS was 0.82 (±0.16) and mean VAS was 0.77 (±0.18); 40.9% of participants exhibited the highest utility values. Compared with population controls, the mean EQ-5D HU was similar (expected mean 0.82, p=0.58) in patients with ACS, but the mean VAS was slightly lower (expected mean 0.79, p<0.001). Patients with ACS who are younger than 60 years had lower HU than the general population (<0.001). In patients with ACS, significant differences were found according to the gender, education and employment status, diabetes, obesity, heart failure, recurrent ischaemic or incident bleeding event and participation in cardiac rehabilitation (p<0.01). Conclusions At 1 year, patients with ACS with coronary angiography had HU indexes similar to a control population. Subgroup analyses based on patients' characteristics and further disease-specific instruments could provide better sensitivity for detecting smaller variations in health-related quality of life.

    Sofosbuvir, a hepatitis C virus (HCV) NS5B polymerase inhibitor, is a new direct-acting antiviral for chronic HCV infection. This systematic review and proportional meta-analysis examined the efficacy and safety of sofosbuvir-based therapy for chronic HCV infection in treatment-naïve and -experienced patients. Medline, Cochrane Database of Systematic Reviews, EMBASE and Web of Science databases were searched. Clinical trials examining sofosbuvir plus ribavirin (RBV) and pegylated interferon-α (peg-IFN) or sofosbuvir plus RBV among adults with chronic HCV infection were included. Data were extracted on virological responses including sustained virological response at post-treatment Week 12 (SVR12), relapse, treatment discontinuation due to an adverse event (AE), virological breakthrough during treatment, and AEs. One trial and 13 treatment arms/cohorts from seven studies met the criteria for analysis in treatment-naïve patients who were treated with sofosbuvir, RBV and peg-IFN; the SVR12 was 89% (95% CI 85-92%), relapse was 5% and the serious adverse event (SAE) rate was 4%. Six treatment arms/cohorts met the criteria for analysis in treatment-naïve patients who were treated with sofosbuvir and RBV; the SVR12 was 72% (95% CI 60-81%), relapse was 27% and the SAE rate was 3%. Three treatment arms/cohorts met the criteria for analysis in treatment-experienced patients who were treated with sofosbuvir and RBV; the SVR12 was 51% (95% CI 27-75%), relapse was 46% and the SAE rate was 4%. In conclusion, sofosbuvir-based treatment is effective and safe in treating chronic HCV infection, although the SVR12 of its combination with RBV, especially in treatment-experienced patients, requires improvement.

    The harm associated with lung cancer treatment include perioperative morbidity and mortality and therapy-induced toxicities in various organs, including the heart and lungs. Optimal treatment therefore entails a need for risk assessment to weigh the probabilities of benefits versus harm. Exercise testing offers an opportunity to evaluate a patient's physical fitness/exercise capacity objectively. In lung cancer, it is most often used to risk-stratify patients undergoing evaluation for lung cancer resection. In recent years, its use outside this context has been described, including in nonsurgical candidates and lung cancer survivors. In this article we review the physiology of exercise testing and lung cancer. Then, we assess the utility of exercise testing in patients with lung cancer in four contexts (preoperative evaluation for lung cancer resection, after lung cancer resection, lung cancer prognosis, and assessment of efficiency of exercise training programs) after systematically identifying original studies involving the most common forms of exercise tests in this patient population: laboratory cardiopulmonary exercise testing and simple field testing with the 6-minute walk test, shuttle walk test, and/or stair-climbing test. Lastly, we propose a conceptual framework for risk assessment of patients with lung cancer who are being considered for therapy and identify areas for further studies in this patient population.

    Background: Patients with relapsing–remitting multiple sclerosis (RRMS) may experience breakthrough disease despite effective interferon beta (IFNβ) therapy. Fludarabine (FLU) is a chemotherapeutic agent used in lymphoproliferative disorders that may be synergistic when combined with immunomodulatory therapy to control active multiple sclerosis (MS). Objective: The objective of this study was to explore the safety and tolerability of FLU versus monthly methylprednisolone (MP) in IFNβ-treated RRMS patients with breakthrough disease. Clinical and MRI effects of IFNβ-1a plus FLU were evaluated. Methods: Eighteen patients with breakthrough disease [⩾2 relapses over the prior year and ⩾1.0-point increase in Expanded Disability Status Scale (EDSS) score sustained for ⩾3 months] after >1 year of IFNβ therapy were enrolled in this prospective, open-label, randomized, proof-of-concept, pilot study. Patients received intravenous (IV) MP 1 g daily for 3 days and then were randomized to receive 3 monthly IV infusions of FLU 25 mg/m2 daily for 5 consecutive days (n = 10) or MP 1 g (n = 8). All patients maintained their intramuscular IFNβ-1a treatment throughout the study. Analyses explored safety signals and directional trends; this preliminary study was not powered to detect clinically meaningful differences. Results: Both combination treatments were safe and well tolerated, with all adverse events mild. Patients treated with IFNβ-1a plus FLU had similar relapse rates, EDSS scores, and MS Functional Composite scores, but significantly less acute corticosteroid use for on-study relapses and better responses on some MRI outcomes, versus patients treated with IFNβ-1a plus MP. Conclusions: Further study of FLU for breakthrough disease in patients with RRMS is warranted. PMID:27006698

    Objectives This study explores surrogate decision-makers’ (SDMs) challenges making decisions related to the care of patients in critical care, to 1) characterize the SDM stress 2) identify personal, social, care-related factors influencing stress and 3) consider implications of findings to improving critical care practice. Methodology Semi-structured interviews were conducted with SDMs of critically ill patients receiving care in two tertiary care institutions. Transcripts were analyzed using a grounded theory approach. Domains explored were: stress characteristics, stress mitigators, coping strategies, social networks, SDM decision-making role, decision-making concordance, knowledge of patient's preferences, experience with provider team, SDM-provider communication, patient outcome certainty. Main Outcomes We interviewed 34 SDMs. Most were female and described long-term relationships with patients. SDMs described the strain of uncertain outcomes and decision-making without clear, consistent information from providers. Decision-making anxiety was buffered by SDMs’ active engagement of social networks, faith and access to clear communication from providers. Conclusion Stress is a very real factor influencing SDMs confidence and comfort making decisions. These findings suggest that stress can be minimized by improving communication between SDMs and medical providers. Nurses central role in ICU make them uniquely poised to spearhead interventions to improve provider-SDM communication and reduce SDM decision-making anxiety. PMID:24211047

    Aim: The purpose of this study was to investigate continuity of care in the psychiatric healthcare system from the perspective of patients, including vulnerable groups such as immigrants and refugees. Method: The study is based on 19 narrative interviews conducted with 15 patients with diverse migration backgrounds (immigrants, descendents, refugees, and ethnic Danes). Patients were recruited from a community psychiatric centre situated in an area with a high proportion of immigrants and refugees. Data were analysed through the lens of a theoretical framework of continuity of care in psychiatry, developed in 2004 by Joyce et al., which encompasses four domains: accessibility, individualised care, relationship base and service delivery. Results: Investigating continuity of care, we found issues of specific concern to immigrants and refugees, but also commonalities across the groups. For accessibility, areas pertinent to immigrants and refugees include lack of knowledge concerning mental illness and obligations towards children. In terms of individualised care, trauma, additional vulnerability, and taboo concerning mental illness were of specific concern. In the domain of service delivery, social services included assistance with immigration papers for immigrants and refugees. In the relationship base domain, no differences were identified. Implications for priority area: The treatment courses of patients in the psychiatric field are complex and diverse and the patient perspective of continuity of care provides important insight into the delivery of care. The study highlights the importance of person-centred care irrespective of migration background though it may be beneficial to have an awareness of areas that may be of more specific concern to immigrants and refugees. Conclusions: The study sheds light on concerns specific to immigrants and refugees in a framework of continuity of care, but also commonalities across the patient groups. PMID:25233017

    An important focus for meaningful use criteria is to engage patients in their care by allowing them online access to their health information, including test results. There has been little evaluation of such initiatives. Using a mixed methods analysis of electronic health record data, surveys, and qualitative interviews, we examined the impact of allowing patients to view their test results via patient portal in one large health system. Quantitative data were collected for new users and all users of the patient portal. Qualitative interviews occurred with patients who had received an HbA1c or abnormal Pap result. Survey participants were active patient portal users. Our main measures were patient portal usage, factors associated with viewing test results and utilizing care, and patient and provider experiences with patient portal and direct release. Usage data show 80% of all patient portal users viewed test results during the year. Of survey respondents, 82.7% noted test results to be a very useful feature and 70% agreed that patient portal has made their provider more accessible to them. Interviewed patients reported feeling they should have direct access to test results and identified the ability to monitor results over time and prepare prior to communicating with a provider as benefits. In interviews, both patients and physicians reported instances of test results leading to unnecessary patient anxiety. Both groups noted the benefits of results released with provider interpretation. Quantitative data showed patient utilization to increase with viewing test results online, but this effect is mitigated when results are manually released by physicians. Our findings demonstrate that patient portal access to test results was highly valued by patients and appeared to increase patient engagement. However, it may lead to patient anxiety and increase rates of patient visits. We discuss how such unintended consequences can be addressed and larger implications for

Usage data show 80% of all patient portal users viewed test results during the year. Of survey respondents, 82.7% noted test results to be a very useful feature and 70% agreed that patient portal has made their provider more accessible to them. Interviewed patients reported feeling they should have direct access to test results and identified the ability to monitor results over time and prepare prior to communicating with a provider as benefits. In interviews, both patients and physicians reported instances of test results leading to unnecessary patient anxiety. Both groups noted the benefits of results released with provider interpretation. Quantitative data showed patient utilization to increase with viewing test results online, but this effect is mitigated when results are manually released by physicians. Our findings demonstrate that patient portal access to test results was highly valued by patients and appeared to increase patient engagement. However, it may lead to patient anxiety and increase rates of patient visits. We discuss how such unintended consequences can be addressed and larger implications for

    Background To assess factors associated with visits to GPs, orthopaedists, and non-physician practitioners of complementary medicine (alternative practitioners) by primary care patients with osteoarthritis (OA). Methods Cross-sectional survey among 1250 consecutively addressed patients from 75 primary care practices in Germany. All patients suffered from OA of the knee or hip according to ACR criteria. They received questionnaires collecting sociodemographic data, data about health service utilisation, prescriptions, comorbidities. They also included established instruments as the Arthritis Impact Measurement Scale (AIMS2-SF) to assess disease-specific quality of life and the Patient Health Questionnaire (PHQ-9) to assess depression. Hierarchical stepwise multiple linear regression models were used to reveal significant factors influencing health service utilization. Results 1021 of 1250 (81.6%) questionnaires were returned. Nonrespondents did not differ from participants. Factors associated with health service use (HSU) varied between providers of care. Not being in a partnership, achieving a high score on the PHQ-9, increased pain severity reflected in the “symptom” scale of the AIMS2-SF, and an increased number of drug prescriptions predicted a high frequency of GP visits. The PHQ-9 score was also a predictor for visits to orthopaedists, as were previous GP contacts, a high score in the "symptom" scale as well as a high score in the "lower limb scale" of the AIMS2-SF. Regarding visits to alternative practitioners, a high score in the AIMS -"social" scale was a positive predictor as older people were less likely to visit them. Conclusion Our results emphasize the need for awareness of psychological factors contributing to the use of health care providers. Addressing the revealed factors associated with HSU appropriately may lead to decreased health care utilization. But further research is needed to assess how this can be done successfully.

    Background  Designing optimal antiretroviral (ARV) salvage regimens for multiclass drug-resistant, human immunodeficiency virus (HIV)-infected patients demands specific clinical skills. Our aim was to assess the virologic and immunologic effects of the treatment recommendations drafted by a peer advisory board to physicians caring for heavily ARV-experienced patients. Methods  We conducted a nationwide, HIV clinic-based, cohort study in Mexico. Adults infected with HIV were assessed for a median of 33 months (interquartile range [IQR] = 22–43 months). These patients had experienced the virologic failure of at least 2 prior ARV regimens and had detectable viremia while currently being treated; their physicians had received therapeutic advice, by a panel of experts, regarding the ARV salvage regimen. The primary endpoint was the incidence of loss of virologic response (plasma HIV-RNA levels of <200 copies per mL, followed by levels above this threshold) during the follow-up assessment using an observed-failure competing risks regression analysis. Results  A total of 611 patients were observed (median ARV therapy exposure = 10.5 years; median prior regimens = 4). The probabilities of virologic failure were 11.9%, 14.4%, 16.9%, and 19.4% at the 12-, 24-, 36-, and 48-month follow-up assessments, respectively. Of the 531 patients who achieved a confirmed plasma HIV-RNA level below 200 copies per mL, the median increase in blood CD4+ T-cell count was 162 cells per mL (IQR = 45–304 cells per mL). Conclusions  In routine practice, a high rate of patients with extensive ARV experience, who received an optimized salvage regimen recommended by a peer advisory committee, achieved a long-term sustained virologic response and immune reconstitution.

    We experienced the airway management of a morbidly obese patient in prone position utilizing PENTAX-Airwayscope (AWS) which is a novel airway device for endotracheal intubation. A 29-year-old man, who was 150 kg in weight and 51.9 kg x m(-2) in body mass index, was scheduled for the discectomy for lumbar disc herniation. After the topical anesthesia with lidocaine spray, the patient lay on his stomach by himself on the table. Following the induction of general anesthesia with ketamine and dexmedetomidine in prone position, an anatomically curved blade (INTLOCK) was inserted to his oral cavity first, then the body of AWS was attached. With the patient breathing spontaneously, we successfully inserted the reinforced endotracheal tube. After the maintenance of anesthesia with continuous infusion of dexmedetomidine, ketamin and remifentanil, the patient awoke clearly without pain and endotracheal tube was removed safely in the prone position. Although the prone position is not the standard position for endotracheal intubation under general anesthesia, our technique could be performed in emergency situations.

  11. Optimizing management of treatment-naïve and treatment-experienced HIV+ patients: the role of maraviroc

    Maraviroc is the first CCR5 antagonist approved for the treatment of HIV-1 infection. It specifically inhibits the replication of R5 viruses by blocking viral entry. HIV-1 tropism can be estimated accurately and predict viral response to maraviroc. Genotypic tools are increasingly replacing phenotypic assays in most places. The favorable pharmacokinetic properties and the good safety profile of maraviroc may support an earlier use of the drug in HIV-1 infection, as well as favor its consideration as part of switch strategies in patients under suppressive antiret-roviral regimens containing less-well-tolerated drugs. Moreover, a particular immune benefit of maraviroc might encourage its use as part of intensification strategies in HIV-infected patients with impaired CD4 gains despite prolonged suppression of HIV replication with antiretroviral therapy. However, the long-term consequences of using maraviroc must be carefully checked, given its particular mechanism of action, blocking a physiologic cell receptor. PMID:22096384

    Abstract We investigated the safety, efficacy, and impact of ribavirin and peginterferon dose reduction on complete early virologic response and sustained virologic response (SVR) to triple therapy with telaprevir in treatment-experienced patients with advanced liver fibrosis. Treatment was initiated for 211 patients who failed treatment with peginterferon and ribavirin, with bridging fibrosis (F3, n = 68) or cirrhosis (F4, n = 143), including 103 (49%) null-responders (NR), 30 (14%) partial responders (PR), and 78 (37%) relapsers (REL). Impaired liver function (ILF) platelets <100,000/mm3 or albumin <35 g/L were present in 40 patients. The distribution of hepatitis C virus subtypes was: 1a, 1b, or 1, with undetermined subtype for 10 (5%), 187 (89%), and 14 (6%) patients, respectively. Treatment was started with peginterferon alpha-2a or alpha-2b, ribavirin, and telaprevir at standard doses. The overall SVR24 rate was 56% and was lower in cirrhotic patients (NR: 35%, PR: 40%, and REL: 63%, respectively) than in patients with bridging fibrosis (NR: 50%, PR: 75%, and REL: 75%, respectively). The lowest probability of SVR24 was in NRs with ILF (26%). The SVR24 rate significantly decreased in NRs receiving <60% vs >60% of the total ribavirin dose (23% vs 44%, respectively) or <80% vs >80% of the total ribavirin dose (33% vs 48%, respectively). A significant SVR24 decrease was noted subsequent to a total peginterferon dose reduction, both when comparing patients who received <60% vs >60% of the total dose (NR: 0% vs 44%; REL: 33% vs 68%) and patients who received <80% vs >80% of the total dose (NR: 17% vs 50%; REL: 46% vs 71%). Serious adverse events were observed in 31 patients (15%). Deaths occurred in 4 patients. All of the deceased subjects were cirrhotic members of the ILF (baseline serum albumin level <35 g/L and/or platelet count <100,000/mm3) group. Ribavirin dose reduction did not affect efficacy in REL but did in NR. Peginterferon dose reduction

    The efficacy and safety of the boceprevir (BOC)-containing triple therapy in Taiwanese treatment-experienced patients remains elusive. After 4 weeks of peginterferon/ribavirin lead-in therapy, patients with cirrhosis or previous null-response received triple therapy for 44 weeks; whereas others received 32 weeks of triple therapy followed by 12 weeks of peginterferon/ribavirin therapy. Patients with HCV RNA > 100 IU/mL at week 12 or with detectable HCV RNA at week 24 of treatment were viewed as futile. A total of 123 patients received treatment. The rates of sustained virological response (SVR) and relapse were 66.7% and 8.9%, respectively by using intention-to-treat analysis. Multivariate analysis revealed that factors associated with SVR included HCV-1b (odds ratio [OR]/ 95% confidence intervals [CI]: 19.23/1.76–525.15, P = 0.01), BOC adherence (7.69/1.55–48.78, P = 0.01), serum albumin (OR/CI:6.25/1.14–40.07, P = 0.03) levels and HCV RNA levels (OR/CI:0.34/0.12–0.79, P = 0.01). Twenty-six (21.1%) patients experienced severe adverse events (SAEs). Multivariate analysis revealed that APRI > 1.5 was the single factor associated with occurring SAEs (OR/CI: 3.77/ 0.97–14.98, P = 0.05). Merging the cut-off values of HCV RNA > 7 log IU/mL at baseline and HCV RNA > 6 log IU/mL at week 4 provided the earliest and best combing viral kinetics in predicting week 12/24 futility with the PPV of 100% and accuracy of 93.5%. HCV-1 treatment experienced Taiwanese patients treated with boceprevir-containing triple therapy in real world had comparable efficacy and safety profiles with those reported in clinical trials. Early viral kinetics before week 4 of treatment highly predicted futility at week 12 or 24 of treatment. PMID:26368130

    Freezing of gait (FOG) in Parkinson's disease (PD) is typically assumed to be a pure motor deficit, although it is important to consider how an abrupt loss of gait automaticity might be associated with an overloaded central resource capacity. If resource capacity limits are a factor underlying FOG, then obstacle crossing may be particularly sensitive to dual task effects in eliciting FOG. Participants performed a dual task (auditory digit monitoring) in order to increase cognitive load during obstacle crossing. Forty-two non-demented participants (14 PD patients with FOG, 13 PD who do not freeze, and 14 age-matched healthy control participants) were required to walk and step over a horizontal obstacle set at 15% of the participants' height. Kinematic data were split into two phases of their approach: early (farthest away from the obstacle), and late (just prior to the obstacle). Interestingly, step length variability and step time variability increased when PD patients with FOG performed the dual task, but only in the late phase prior to the obstacle (i.e. when closest to the obstacle). Additionally, immediately after crossing, freezers landed the lead foot abnormally close to the obstacle regardless of dual task condition, and also contacted the obstacle more frequently (planning errors). Strength of the dual task effect was associated with low general cognitive status, declined executive function, and inappropriate spatial planning, but only in the PD-FOG group. This study is the first to demonstrate that cognitive load differentially impacts planning of the final steps needed to avoid an obstacle in PD patients with freezing, but not non-freezers or healthy controls, suggesting specific neural networks associated with FOG behaviours.

Eleven Thai Buddhist trauma patients were selected as specified. The data were collected by in-depth interviews between November 2011 and April 2012, and analyzed using the Van Manen method.Those interviewed described "holistic self-care for rehabilitation" as learning (1) to acquire a new life and (2) to bear the increased demands of care as a chronic disease. Health care responses fell into 3 categories: (1) improving physical self-sufficiency and rehabilitation by increasing muscle strength, pain management, and pressure sores; (2) improving psychological well-being by applying positive thinking, making an effort to live independently, and following a set of religious practices; and (3) finding harmony in life through caution and a willingness to adjust one's lifestyle. Although the participants seemed to adapt well to their new lifestyles, extensive support from health care professionals was necessary. This study promotes better understanding of the holistic health care experiences the survivors of trauma have as a result of an unstable political situation that includes aspects of social unrest and terrorism.

    Dried blood spots (DBS) are an alternative specimen collection format for HIV-1 genotyping. DBS produce HIV genotyping results that are robust and equivalent to plasma when using conventional sequencing methods. However, using tagged, pooled pyrosequencing, we demonstrate that concordance between plasma and DBS is not absolute and varies according to viral load (VL), duration of HIV infection and antiretroviral therapy (ART) status. The plasma/DBS concordance is the highest when VL is ≥5,000 copies/ml and/or the patient has no ART exposure and/or when the duration of HIV infection is ≤2 years. Stepwise regression analysis revealed that VL is most important independent predictor for concordance of DBS with plasma genotypes. This is the first study to use next generation sequencing to identify discordance between DBS and plasma genotypes. Consideration should be given to VL, duration of infection, and ART exposure when interpreting DBS genotypes produced using next generation sequencing. These findings are of particular significance when DBS are to be used for clinical monitoring purposes. PMID:23409150

    People with complex chronic conditions frequently need to navigate their own way through and around a fragmented and siloed health care system. Care coordination is a defining principle of primary care and is frequently proposed as a solution to this problem. However, care coordination requires more time and effort than primary care physicians alone have the capacity to deliver. Although registered nurses (RNs) are skilled team members who can be included in the delivery of coordinated patient care, any model of care coordination that involves RNs needs to fit within the existing health care delivery system. In this study, which used qualitative techniques based on grounded theory and included face-to-face interviews and open coding and theoretical sampling until data saturation was achieved, and which was one component of a larger action research study, we aimed to gain an understanding of the difference between usual chronic condition care and the work of chronic condition care coordination. The researchers interviewed general practitioners and RNs from various general practice sites who were actively coordinating care. Four unique processes were found to define care coordination implementation, namely: (1) moving beyond usual practice by spanning boundaries; (2) relationship-based care; (3) agreed roles and routines among relevant parties; and (4) committing to chronic condition care coordination. The findings suggested that existing professional and organisational cultures required negotiation before care coordination could be integrated into existing contexts. The challenge, however, seems to be in acknowledging and overcoming professional practice boundaries that define existing care through reflective practice and shared resourcing.

    COMT Val(158)Met moderates the effect of stress on psychotic symptoms. Exposure to stress is also associated with mesolimbic dopamine release in individuals experiencing low maternal care. We therefore test the hypothesis that recent stressful life events are associated with more severe positive symptoms (associated with mesolimbic dopamine release) in first-episode psychosis (FEP) patients who experienced low maternal care during childhood. We hypothesized that COMT Val(158)Met moderates this association. A total of 149 FEP patients recruited within the Psychosis Incident Cohort Outcome Study (PICOS) participated in the present study. Maternal care was assessed by the Parental Bonding Instrument (PBI), stressful life events were collected by the List of Events Scale and positive symptoms were assessed by the Positive and Negative Syndrome Scale (PANSS). We found that low maternal care and recent stressful life events were associated with higher level of positive symptoms at the onset (analysis of variance [ANOVA], p = 0.012), and that patients who were also homozygotes for the COMT Val(158) allele had the highest level of positive symptoms (ANOVA, p = 0.024). Low maternal care and severe stressful life events may contribute to a symptomatology characterized by more severe positive symptoms at the onset, possibly due to an increased mesolimbic dopamine release. Homozygosity for the COMT Val(158) allele seems to confer a biological predisposition to the stress-related hyperactivity of the mesolimbic dopaminergic system. The data imply that the mesolimbic dopaminergic system is involved in the mediation/modulation of the effect of stressful events on the vulnerability for psychosis.

    Since the 1980s, major surgical interventions in patients with congenital haemophilia with inhibitors have been performed utilizing bypassing agents for haemostatic coverage. While reports have focused on perioperative management and haemostasis, the US currently lacks consensus guidelines for the management of patients with inhibitors during the surgical procedure, and pre- and postoperatively. Many haemophilia treatment centres (HTCs) have experience with surgery in haemophilia patients, including those with inhibitors, with approximately 50% of these HTCs having performed orthopaedic procedures. The aim of this study was to present currently considered best practices for multidisciplinary care of inhibitor patients undergoing surgery in US HTCs. Comprehensive haemophilia care in the US is provided by ~130 federally designated HTCs staffed by multidisciplinary teams of healthcare professionals. Best practices were derived from a meeting of experts from leading HTCs examining the full care spectrum for inhibitor patients ranging from identification of the need for surgery through postoperative rehabilitation. HTCs face challenges in the care of inhibitor patients requiring surgery due to the limited number of surgeons willing to operate on this complex population. US centres of excellence have developed their own best practices around an extended comprehensive care model that includes preoperative planning, perioperative haemostasis and postoperative rehabilitation. Best practices will benefit patients with inhibitors and allow improvement in the overall care of these patients when undergoing surgical procedures. In addition, opportunities for further education and outcomes assessment in the care of this patient population have been identified.

    Ivermectin (IVM) is exceptionally safe in humans, and is used for mass treatment of onchocerciasis and lymphatic filariasis. However, cases of encephalopathy, sometimes fatal, have been reported in a small number of individuals who harbored large numbers of Loa loa microfilariae (mf). A loss-of-function mutation in the mdr-1 gene in some dog breeds and in mice leads to accumulation of the drug in the brain, causing coma and death. This hypothesis was tested in four individuals from Cameroon who experienced a post-IVM serious adverse event (SAE) and in nine non-SAE matched controls. No loss-of-function mutation was detected in mdr-1 in any subject. However, haplotypes, associated with altered drug disposition, were present as homozygotes in two of the SAE patients (50%), but absent as homozygotes in the controls (0%). An association of high Loa mf load and a genetic predisposition to altered IVM distribution could be involved in IVM SAEs. PMID:20595473

    Objectives The objectives of this study were to estimate the impact of recruitment source and outcome definition on the incidence of acute exacerbations of COPD (AECOPD) and explore possible predictors of AECOPD. Patients and methods During a 1-year follow-up, we performed a baseline visit and four telephone interviews of 81 COPD patients and 132 controls recruited from a population-based survey and 205 hospital-recruited COPD patients. Both a definition based on health care utilization and a symptom-based definition of AECOPD were applied. For multivariate analyses, we chose a negative binomial regression model. Results COPD patients from the population- and hospital-based samples experienced on average 0.4 utilization-defined and 2.9 symptom-defined versus 1.0 and 5.9 annual exacerbations, respectively. The incidence rate ratios for utilization-defined AECOPD were 2.45 (95% CI 1.22–4.95), 3.43 (95% CI 1.59–7.38), and 5.67 (95% CI 2.58–12.48) with Global Initiative on Obstructive Lung Disease spirometric stages II, III, and IV, respectively. The corresponding incidence rate ratios for the symptom-based definition were 3.08 (95% CI 1.96–4.84), 3.45 (95% CI 1.92–6.18), and 4.00 (95% CI 2.09–7.66). Maintenance therapy (regular long-acting muscarinic antagonists, long-acting beta-2 agonists, inhaled corticosteroids, or theophylline) also increased the risk of AECOPD with both exacerbation definitions (incidence rate ratios 1.65 and 1.73, respectively). The risk of AECOPD was 59%–78% higher in the hospital sample than in the population sample. Conclusion If externally valid conclusions are to be made regarding incidence and predictors of AECOPD, studies should be based on general population samples or adjustments should be made on account of a likely higher incidence in other samples. Likewise, the effect of different AECOPD definitions should be taken into consideration.

    Objectives The objectives of this study were to estimate the impact of recruitment source and outcome definition on the incidence of acute exacerbations of COPD (AECOPD) and explore possible predictors of AECOPD. Patients and methods During a 1-year follow-up, we performed a baseline visit and four telephone interviews of 81 COPD patients and 132 controls recruited from a population-based survey and 205 hospital-recruited COPD patients. Both a definition based on health care utilization and a symptom-based definition of AECOPD were applied. For multivariate analyses, we chose a negative binomial regression model. Results COPD patients from the population- and hospital-based samples experienced on average 0.4 utilization-defined and 2.9 symptom-defined versus 1.0 and 5.9 annual exacerbations, respectively. The incidence rate ratios for utilization-defined AECOPD were 2.45 (95% CI 1.22–4.95), 3.43 (95% CI 1.59–7.38), and 5.67 (95% CI 2.58–12.48) with Global Initiative on Obstructive Lung Disease spirometric stages II, III, and IV, respectively. The corresponding incidence rate ratios for the symptom-based definition were 3.08 (95% CI 1.96–4.84), 3.45 (95% CI 1.92–6.18), and 4.00 (95% CI 2.09–7.66).

    Objective To examine how palliative medicine doctors engage patients in end-of-life (hereon, EoL) talk. To examine whether the practice of “eliciting and responding to cues”, which has been widely advocated in the EoL care literature, promotes EoL talk. Design Conversation analysis of video- and audio-recorded consultations. Participants Unselected terminally ill patients and their companions in consultation with experienced palliative medicine doctors. Setting Outpatient clinic, day therapy clinic, and inpatient unit of a single English hospice. Results Doctors most commonly promoted EoL talk through open elaboration solicitations; these created opportunities for patients to introduce–then later further articulate–EoL considerations in such a way that doctors did not overtly ask about EoL matters. Importantly, the wording of elaboration solicitations avoided assuming that patients had EoL concerns. If a patient responded to open elaboration solicitations without introducing EoL considerations, doctors sometimes pursued EoL talk by switching to a less participatory and more presumptive type of solicitation, which suggested the patient might have EoL concerns. These more overt solicitations were used only later in consultations, which indicates that doctors give precedence to patients volunteering EoL considerations, and offer them opportunities to take the lead in initiating EoL talk. There is evidence that doctors treat elaboration of patients’ talk as a resource for engaging them in EoL conversations. However, there are limitations associated with labelling that talk as “cues” as is common in EoL communication contexts. We examine these limitations and propose “possible EoL considerations” as a descriptively more accurate term. Conclusions Through communicating–via open elaboration solicitations–in ways that create opportunities for patients to volunteer EoL considerations, doctors navigate a core dilemma in promoting EoL talk: giving

    Background. The pilot phase IIb VIKING study suggested that dolutegravir (DTG), a human immunodeficiency virus (HIV) integrase inhibitor (INI), would be efficacious in INI-resistant patients at the 50 mg twice daily (BID) dose. Methods. VIKING-3 is a single-arm, open-label phase III study in which therapy-experienced adults with INI-resistant virus received DTG 50 mg BID while continuing their failing regimen (without raltegravir or elvitegravir) through day 7, after which the regimen was optimized with ≥1 fully active drug and DTG continued. The primary efficacy endpoints were the mean change from baseline in plasma HIV-1 RNA at day 8 and the proportion of subjects with HIV-1 RNA <50 c/mL at week 24. Results. Mean change in HIV-1 RNA at day 8 was −1.43 log10 c/mL, and 69% of subjects achieved <50 c/mL at week 24. Multivariate analyses demonstrated a strong association between baseline DTG susceptibility and response. Response was most reduced in subjects with Q148 + ≥2 resistance-associated mutations. DTG 50 mg BID had a low (3%) discontinuation rate due to adverse events, similar to INI-naive subjects receiving DTG 50 mg once daily. Conclusions. DTG 50 mg BID–based therapy was effective in this highly treatment-experienced population with INI-resistant virus.

    The aim of this study was to identify human immunodeficiency virus (HIV) protease mutations associated with virological response (VR) to fosamprenavir-ritonavir (FPV/r) in 113 protease inhibitor (PI)-experienced patients randomized in both CONTEXT and TRIAD clinical trials and receiving the same dose (700/100 mg twice daily) of FPV/r. The impact of each protease mutation on the VR to FPV/r, defined as the decrease in HIV RNA at week 12, was investigated with nonparametric analyses. A step-by-step procedure was done using a Jonckheere-Terpstra (JT) test that retains the group of mutations most strongly associated with the VR. Mutations at the following 14 codons were associated with a reduced VR to FPV/r: 10, 15, 33, 46, 54, 60, 62, 63, 72, 73, 82, 84, 89, and 90. The JT procedure led to selecting the CONTEXT/TRIAD genotypic set of mutations, I15V, M46I/L, I54L/M/V, D60E, L63P/T, and I84V, as providing the strongest association with the VR (P = 1.45 × 10−11). In the nine patients with zero mutations within this set, the median decrease in HIV RNA was −2.63 log copies/ml, and was −2.22 (n = 45), −1.50 (n = 26), −0.58 (n = 23), −0.47 (n = 6), −0.13 (n = 3), and 0.04 (n = 1) log copies/ml in those with one, two, three, four, five, and six mutations, respectively. This study identified six mutations associated with VR to FPV/r. Some of these mutations are shared with the current FPV/r Agence Nationale de Recherches sur le SIDA (ANRS) resistance score, which has been cross-validated in the CONTEXT/TRIAD data set, suggesting that the current ANRS FPV/r score is a useful tool for the prediction of VR to FPV/r in PI-experienced patients.

    Psychological distress is a well-known complication in rheumatoid arthritis (RA), but knowledge regarding emotions and their relationship to participation restrictions is scarce. The objective of the study was to explore emotions related to participation restrictions by patients with early RA. In this study, 48 patients with early RA, aged 20-63 years, were interviewed about participation restrictions using the critical incident technique. Information from transcribed interviews was converted into dilemmas and linked to International Classification of Functioning, Disability, and Health (ICF) participation codes. The emotions described were condensed and categorized. Hopelessness and sadness were described when trying to perform daily activities such as getting up in the mornings and getting dressed, or not being able to perform duties at work. Sadness was experienced in relation to not being able to continue leisure activities or care for children. Examples of fear descriptions were found in relation to deteriorating health and fumble fear, which made the individual withdraw from activities as a result of mistrusting the body. Anger and irritation were described in relation to domestic and employed work but also in social relations where the individual felt unable to continue valued activities. Shame or embarrassment was described when participation restrictions became visible in public. Feelings of grief, aggressiveness, fear, and shame are emotions closely related to participation restrictions in everyday life in early RA. Emotions related to disability need to be addressed both in clinical settings in order to optimize rehabilitative multi-professional interventions and in research to achieve further knowledge.

    Background Patients with differentiated thyroid cancer (DTC) often respond well to treatment but some become refractory to radioactive iodine (RAI) treatment, and treatment options are limited. Despite the humanistic and economic burden RAI refractory disease imposes on patients, published research concerning treatment patterns and health care resource utilization is sparse. Methods Data were collected from an online retrospective chart review study in the US and five European Union (EU) countries (France, Germany, Italy, Spain, and UK) with physicians recruited from an online panel. Physicians (N=211) provided demographics, disease history, treatment information, and health care resource utilization for one to four of their patients with radioactive iodine refractory differentiated thyroid cancer (RR-DTC). Results The majority of the patients with RR-DTC (N=623) were female (56%), and their mean age was 58.2 years. In this sample, 63.2% had papillary thyroid cancer and 57.0% were in Stage IV when deemed RAI refractory. Patients with RR-DTC experienced regional recurrence in the thyroid bed/central neck area (25.3%) and had distant metastatic disease (53.6%). At the time data were collected, 50.7% were receiving systemic treatment. Of those, 78.5% were on first-line treatment and 62.7% were receiving multikinase inhibitors. Regional differences for prescribed treatments were observed; the US was more likely to have patients receiving multikinase inhibitors (79.2%) compared with UK (41.2%) and Italy (17.1%). Additional details regarding treatment patterns and resource utilization are discussed. Conclusion The current study aimed to obtain a greater understanding of RR-DTC treatment globally. These results can assist in the development and implementation of treatment guidelines and ultimately enhance the care of patients with RR-DTC. PMID:27313476

    Health utilization and need assessment data suggest there is considerable variation in access to outpatient specialist care. However, it is unclear if the types of barriers experienced are specific to chronic disease groups or experienced universally. This systematic review provides a detailed summary of common and unique barriers experienced by chronic disease groups when accessing and receiving care, and a synthesized list of possible health service initiatives to improve equitable delivery of optimal care in high-income countries. Quantitative articles describing barriers to specialist outpatient services were retrieved from CINAHL, MEDLINE, Embase, and PyscINFO. To be eligible for review, studies: were published from 2002 to May 2014; included samples with cancer, diabetes mellitus, osteoporosis, arthritis, ischaemic heart disease, stroke, asthma, chronic pulmonary disorder (COPD) or depression; and, were conducted in high-income countries. Using a previously validated model of access (Penchansky and Thomas' model of fit), barriers were grouped according to five overarching domains and defined in more detail using 33 medical subject headings. Results from reviewed articles, including the scope and frequency of reported barriers, are conceptualized using thematic analysis and framed as possible health service initiatives. A total of 3181 unique records were screened for eligibility, of which 74 studies were included in final analysis. The largest proportion of studies reported acceptability barriers (75.7 %), of which demographic disparities (44.6 %) were reported across all diseases. Other frequently reported barriers included inadequate need assessment (25.7 %), information provision (32.4 %), or health communication (20 %). Unique barriers were identified for oncology, mental health, and COPD samples. Based on the scope, frequency and measurement of reported barriers, eight key themes with associated implications for health services are presented. Examples

    2012-03-01

    The issue of nurse-to-patient ratios has been of significant interest to nurses in Saskatchewan. A commitment to a nurse-to-patient pilot project was articulated in a letter of understanding in the 2005 to 2008 contract between the Saskatchewan Union of Nurses (SUN) and the Saskatchewan Association of Health Organizations. The SUN, the Saskatoon Health Region and the Saskatchewan Ministry of Health formed a partnership to engage in the pilot project, which lasted from November 2008 to March 2011. The project involved the creation of a flexible, dynamic and real-time staffing tool to inform day-to-day nurse staffing decisions on a hospital unit and was based on an adaptation of Curley's Synergy Model. A medical unit at St. Paul's Hospital in Saskatoon was selected for implementation, and all front-line nursing staff as well as unit nursing leaders were involved. A project working group adapted the Synergy-based Patient Scoring Tool (PST), which had been utilized for a recent project in British Columbia, to its own patient population. In April 2010, nurses began assessing each patient on every shift with the goal of determining the most suitable care provider. Patient assignment became based on the holistic assessment of patient needs according to the PST results rather than "geography" (for example, one nurse assigned to a multi-bed unit regardless of the acuity/capability of patients in the unit). Whenever possible, staffing on the unit was increased according to tool calculations.Positive impacts in patient outcomes began to be noted during the final data collection period for the project – nosocomial infection rates showed improvement, and the number of falls per patient-days decreased. As well, patient needs were made more visible through use of the PST, which created non-threatening opportunities for dialogue related to legislated scopes of practice. While longer timelines and larger sample size are needed to measure impacts on retention and recruitment of

    Finding differences in drug utilization patterns within rare patient populations is challenging without access to a large sample. Our objective was to identify patient and treatment-related factors associated with differences in annual recombinant factor VIII (rFVIII) utilization in a large cohort of haemophilia A patients. This retrospective analysis utilized a large, US specialty pharmacy dispensing database from January 2006 to September 2009. Differences in median annual FVIII utilization (IU kg(-1) year(-1)) by age, severity, treatment regimen, rFVIII product type and health insurance plan were tested using non-parametric statistics and regression analysis. A total of 1011 haemophilia A patients were included in the overall analysis. Severe haemophilia patients had higher median annual FVIII utilization than mild/moderate patients (P < 0.0001). Median annual FVIII utilization was also significantly different between treatment regimens (episodic = 1429 IU kg(-1) year(-1) vs. prophylaxis = 3993 IU kg(-1) year(-1) for severe patients, P < 0.0001). Children (0-12 years old), adolescents (13-18 years old) and adults (19+ years old) with severe haemophilia A receiving prophylaxis utilized 4588, 4082 and 3223 IU kg(-1) year(-1) (P < 0.0001). After controlling for age, severity, treatment regimen and insurance type, regression analysis revealed B domain-deleted recombinant FVIII (BDD-rFVIII) was associated with 33% higher FVIII consumption compared with full-length recombinant FVIII (FL-rFVIII) (P = 0.0172). Similar results were also seen when matching BDD-rFVIII and FL-rFVIII patients. Health insurance type was not associated with annual FVIII utilization. As expected, age, severity and treatment regimen were significantly associated with FVIII utilization. After controlling for confounders, patients receiving FL-rFVIII prophylactically were associated with lower annual FVIII utilization compared with patients receiving BDD-rFVIII prophylactically.

    To prepare for Medicaid managed care, a community health center incorporated the business principle of continuous quality improvement, often used in the private sector to improve customer service, into its planning process. The initial endeavor was to create a patient satisfaction survey that was appropriate for the uniqueness of the community. The survey, taken monthly, resulted in both staff and patients making active improvements in the clinic environment. Staff showed more enthusiasm, and patients were more assertive in their attitudes toward the clinic. The empowerment of the patient to take ownership in the clinic will be coupled with the next step of the formalized plan, that of educating patients on the steps necessary to ensure that their Medicaid managed care facility will be the local community health center.

    Objetive: Fibromyalgia (FM) is a chronic pain syndrome with unknown etiology, which affects predominantly women. Mitochondrial alteration could have a role in the pathophysilogical mechanisms of inflammatory conditions as FM and periodontitis. The aim of the present study was assay the relationship between both diseases and mitochondrial dysfunction. Patient and Methods: We study the presence of periodontitis in twelve patients diagnosed of FM and mitochondrial dysfunction described. The diagnosis of FM was established according to ACR criteria and clinical symptoms were evaluated using the Fibromyalgia Impact Questionnaire (FIQ) and Beck Depression Inventory (BDI). Results: Only one patients of twelve included and agreed to participate in the study were diagnosed with periodontitis. Conclusions: Pending studies with larger numbers of patients, we can conclude that mitochondrial dysfunction in FM is a itself event not related with periodontitis. Periodontitis could be considered a exclusion criterion in all studies about mitochondrial dysfunction in patients. Key words:Peridontitis, fibromyalgia, mitocondrial dysfunction, oxidative stress.

    The purpose of this study was to determine the frequency of changes in patient care resulting from the use of a surgical safety checklist. Data were retrospectively obtained from 233 patients. The number and types of changes made to the patients' intra-operative management, based on the use of the checklist, were recorded. The number of patients whose management was modified as a result of the checklist was 113 (48%) out of 233. The total number of changes made was 132, and 18 patients had more than one modification made to their care plan. Further stratification was identified: among the 132 changes made, antibiotics were held or administered in 73 (55%), changes related to anaemia involving type and screen or transfusion occurred in 27 (20%), modifications made regarding anti-coagulation occurred in 8 (7%), beta-blockers were held in 2 (2%), an allergy was identified in 7 (5%), modifications made to the surgical procedure were 3 (2%) and a category labelled 'other' encompassed 9 (7%) changes. The surgical safety checklist is a standardised form of team communication that leads to modifications of the patient care plan in a large percentage of cases. The ever-increasing complexity of medicine means that patients are at greater risk of oversight and harm without the use of a checklist. PMID:25585543

    Shared decision-making is a complex endeavor that should take into account the patient's personal preferences regarding treatment options. To truly empower patients to be partners in decision-making, especially in situations in which their preferences are important, physicians must learn to communicate better and to distinguish between what is "medical fact" versus a "value judgement." Knowing what are, when to ask, and how to ask the right questions will help physicians be effective in guiding patients toward the right treatments. PMID:27226516

    Objective To evaluate the conversion of opioid-experienced patients with chronic moderate-to-severe pain to extended-release morphine sulfate with sequestered naltrexone hydrochloride (MSN) using a standardized conversion guide. Methods This open-label, single-arm study was conducted in 157 primary care centers in the United States. A total of 684 opioid-experienced adults with chronic moderate-to-severe pain were converted to oral administration of MSN from transdermal fentanyl and oral formulations of hydrocodone, hydromorphone, methadone, oxycodone, oxymorphone, and other morphine products using a standardized conversion guide. The primary endpoint was the percentage of patients achieving a stable MSN dose within a 6-week titration phase. Secondary endpoints included duration of time to stable dose, number of titration steps, safety and efficacy measures, and investigator assessment of conversion guide utility. Results Of the 684 patients, 51.3% were converted to a stable dose of MSN (95% confidence interval: 47.5%, 55.1%). The mean (standard deviation) number of days to stable dose was 20 (8.94), and number of titration steps to stable dose was 2.4 (1.37). The majority of adverse events were mild/moderate and consistent with opioid therapy. Mean pain scores at stable dose decreased from baseline. Investigators were generally satisfied with the conversion guide and, in 94% of cases, reported they would use it again. Conclusion Conversion to MSN treatment using the standardized MSN conversion guide was an attainable goal in approximately half of the population of opioid-experienced patients with chronic moderate-to-severe pain. Investigators found the guide to be a useful tool to assist conversion of opioid-experienced patients to MSN. PMID:26185466

    Many studies have tested clinical and behavioral approaches for improving glycemic control in people with diabetes. We review research to identify how blood glucose (BG) values have been used in patient-focused clinical research and interventions. We sought to describe the frequency that BG values have been the focus of patient education research and to characterize the different methods to integrate BG into an intervention, the approaches implemented to support patient education and behavior change, and the nature of communication about BG values. Thirty-four eligible studies were identified that included patient education using BG values. Information regarding the study and intervention characteristics include: 1) Characteristics of the study sample, 2) How BG values were obtained, 3) Use of a graphical interface for BG values, 4) Use of a BG log, 5) BG interpretation and regimen adjustments, 6) Recommended actions to patient, 7) Modality of intervention, and 8) Intervention communication schedule. The review demonstrated that new BG technologies provide outstanding opportunities for greater access to BG data, and for patient support and intervention. However, it also indicated a need to improve and expand support for people with diabetes in their daily use of BG values to maintain and improve glycemic control. In order to make the most sustainable impact on behavior, generalizable skills such as problem solving need to be integrated into BG education. PMID:24057927

    Summary Background The chance of a good response in RA is attenuated in previous anti-TNF users who start new anti-TNF therapy compared to biologic naïve patients. In active RA, those with previous anti-TNF exposure compared to anti-TNF naïve may have different baseline disease activity and patient perceptions when starting a new anti-TNF treatment that could explain the observed response differences. Material/Methods The aim of this study was a post hoc analysis of baseline characteristics of patients enrolled in the Optimization of Adalimumab study that was a treat to target vs. routine care study in patients initiating adalimumab. As per the protocol, a maximum of 20% anti-TNF experienced patients were enrolled in the 300 patient trial. Twelve (4.0%) were excluded who previously used other biologics. Baseline characteristics including age, gender, tender and swollen joint counts, disease activity (DAS28), function (HAQ-DI), patient global assessment, patient satisfaction with current treatment, and inflammatory markers (CRP, ESR), were compared between previously anti-TNF experienced [etanercept or infliximab (EXP)], and anti-TNF naïve patients (NAÏVE). Results The mean (SD) age was 54.8 (13.3) years; 81.0% were female, and 237 (79.0%) were anti-TNF naïve while 51 (17.0%) patients were anti-TNF experienced (29 with etanercept, 16 with infliximab, and 6 for both). The mean (SD) baseline in EXP versus NAÏVE groups respectively was: CRP=21.7(32.9) vs. 17.5(20.7); ESR=28.7(22.5) vs. 29.8(20.4); SJC=10.5(6.0) vs. 10.7(5.6); TJC=12.8(7.1) vs. 12.3(7.3); and DAS28=6.0(1.2) vs. 5.8(1.1). None of the between-group differences were statistically significant, however, the HAQ-DI in EXP was 1.7(0.6) compared to 1.5(0.7) for the NAÏVE (P=0.021). Additionally, EXP patients had a higher patient global score [71.3(26.1) vs. 61.9(26.2), P=0.021]. Conclusions Although anti-TNF naïve and experienced patients who initiated adalimumab were similar, with respect to several

    Endoscopic ultrasound (EUS) has revolutionized the diagnostic and therapeutic approach to patients with gastrointestinal disorders. Its application in patients with liver disease and portal hypertension is increasing. Patients with chronic liver disease are at risk for development of portal hypertension sequale such as ascites, spontaneous bacterial peritonitis and gastroesophageal varices. Bleeding esophageal and gastric varices are among the most common causes of mortality in patients with cirrhosis. Thus, early detection and treatment improve the outcome in this population. EUS can improve the detection and diagnosis of gastroesophageal varices and collateral veins and can provide endoscopic therapy of gastroesophageal varices such as EUS-guided sclerotherapy of esophageal collateral vessels and EUS-guided cynoacrylate (Glue) injection of gastric varices. EUS can also provide knowledge on the efficacy of pharmacotherapy of portal hypertension. Furthermore, EUS can provide assessment and prediction of variceal recurrence after endoscopic therapy and assessment of portal hemodynamics such as E-Flow and Doppler study of the azygous and portal veins. Moreover, EUS-guided fine needle aspiration may provide cytologic diagnosis of focal hepatic tumors and analysis of free abdominal fluid. Using specialized EUS-guided needle biopsy, a sample of liver tissue can be obtained to diagnose and evaluate for chronic liver disease. EUS-guided fine needle injection can be used to study portal vein pressure and hemodynamics, and potentially could be used to assist in exact measurement of portal vein pressure and placement of intrahepatic portosystemic shunt.

    The use of negative pressure wound therapy (NPWT) has been widely documented as a technique to help heal complex wounds. This article presents the findings of a preliminary study which aimed to explore quality of life (QoL) experienced by patients undergoing NPWT as part of their wound care treatment in comparison to that of patients with a wound using traditional (standard) wound care therapies. A quasi-experimental study was undertaken, with patients treated in wound care/vascular clinics with chronic/acute wounds. QoL impact was measured using the Cardiff Wound Impact Schedule and administered post-consent at timed intervals. Our results identified that there were no real differences in QoL scores recorded by patients over the 12-week period. Although there was no overall interaction between the therapies used for wound healing, NPWT did have an effect on social life: during the first 2 weeks of the application of therapy, patients in the NPWT group reported an increase in the social life domain. The authors conclude that true QoL can only be elicited if an accurate baseline is established or if data is collected over a long enough period to allow comparison of scores over time.

    Accelerated partial breast irradiation (APBI) represents an evolving technique that is a standard of care option in appropriately selected woman following breast conserving surgery. While multiple techniques now exist to deliver APBI, interstitial brachytherapy represents the technique used in several randomized trials (National Institute of Oncology, GEC-ESTRO). More recently, many centers have adopted applicator-based brachytherapy to deliver APBI due to the technical complexities of interstitial brachytherapy. The purpose of this article is to review methods to evaluate and select patients for APBI, as well as to define potential workflow mechanisms that allow for the safe and effective delivery of APBI. Multiple consensus statements have been developed to guide clinicians on determining appropriate candidates for APBI. However, recent studies have demonstrated that these guidelines fail to stratify patients according to the risk of local recurrence, and updated guidelines are expected in the years to come. Critical elements of workflow to ensure safe and effective delivery of APBI include a multidisciplinary approach and evaluation, optimization of target coverage and adherence to normal tissue guideline constraints, and proper quality assurance methods.

The cost of drugs per treatment episode was Ug.Sh.5785.00 in the outpatient and Ug.Sh.8309.00 for inpatients. (The exchange rate for 1991 was US$ = Ug.Sh.910.00). Analysis of an attempt to provide essential drugs for the growing number of AIDS subjects shows that drugs alone could consume the entire health budget of the Ministry of Health in Uganda. There is therefore need to critically consider options to control the high cost for drugs in AIDS care.

    Hepatocellular carcinoma (HCC) is a deadly form of liver cancer that is increasingly prevalent. We analyzed global gene expression profiling of 361 HCC tumors and 49 adjacent noncancerous liver samples by means of combinatorial network-based analysis. We investigated the correlation between transcriptome and proteome of HCC and reconstructed a functional genome-scale metabolic model (GEM) for HCC. We identified fundamental metabolic processes required for cell proliferation using the network centric view provided by the GEM. Our analysis revealed tight regulation of fatty acid biosynthesis (FAB) and highly significant deregulation of fatty acid oxidation in HCC. We predicted mitochondrial acetate as an emerging substrate for FAB through upregulation of mitochondrial acetyl-CoA synthetase (ACSS1) in HCC. We analyzed heterogeneous expression of ACSS1 and ACSS2 between HCC patients stratified by high and low ACSS1 and ACSS2 expression and revealed that ACSS1 is associated with tumor growth and malignancy under hypoxic conditions in human HCC.

    Two surveys of individuals with fibromyalgia were conducted to assess the frequency and prevalence of symptoms (N = 99) as well as healthcare providers, medications, and self-care activities used to manage one's fibromyalgia (N = 54). The pervasiveness of symptoms was striking, with 24 various symptoms ranging from cognitive to intestinal problems occurring in at least 75% of the respondents. Significant correlations were present between health status and both physical (P = .002) and psychological (P =.008) symptoms. There was also a significant correlation between the total number of symptoms and the degree of life disruption attributed to fibromyalgia (P =.015). A variety of healthcare professionals were seen, with internists, family physicians, and rheumatologist most frequently used. Although at least 80% of the respondents reported difficulty with anxiety, confusion, irritability, depression, and cognitive difficulties, less than 10% of the respondents reported seeing a psychiatrist. Most frequently used medications were: amitriptyline, (fluoxetine HCl) Prozac, ibuprofen (Motrin), sertraline HCI (Zoloft), and zolpidem (Ambein). Self-care activities used with the most success were walking, stretching, and exercising. These studies indicate the need for more research and support for healthcare providers as well as patients with fibromyalgia. PMID:11839925

  13. The clinical utility of lurasidone in schizophrenia: patient considerations.

    PubMed

    Harvey, Philip D

    2015-01-01

    Lurasidone is a novel antipsychotic agent approved for the treatment of schizophrenia in a number of countries including the United Kingdom, other European countries, the United States, and Canada. In addition to full antagonist activity at the dopamine D2 (Ki, 1 nM) and serotonin 5-HT2A (Ki, 0.5 nM) receptors, the pharmacodynamic profile of lurasidone is notable for its high affinity for serotonin 5-HT7 receptors (0.5 nM) and its partial agonist activity at 5-HT1A receptors (Ki, 6.4 nM). Long-term treatment of schizophrenia with lurasidone has been shown to reduce the risk of relapse in patients with schizophrenia. Lurasidone appears to be associated with minimal effects on body weight, and low risk for clinically meaningful alterations in glucose, lipids, or electrocardiography parameters. Evidence from two randomized trials also suggests improvement in functional capacity and cognitive functioning in people with schizophrenia. A significant evidence base supports the use of lurasidone as a promising agent for the treatment of schizophrenia.

    Purpose To examine imaging utilization in a matched cohort of patients with and without implantable cardioverter defibrillators (ICD) and to project magnetic resonance imaging (MRI) utilization over a 10‐year period. Materials and Methods The Truven Health MarketScan Commercial claims and Medicare Supplemental health insurance claims data were used to identify patients with continuous health plan enrollment in 2009–2012. Patients with ICDs were identified using ICD‐9 and CPT codes, and matched to patients with the same demographic and comorbidity profile, but no record of device implantation. Diagnostic imaging utilization was compared across the matched cohorts, in total, by imaging categories, and in subpopulations of stroke, back pain, and joint pain. MRI use in the nonimplant group over the 4‐year period was extrapolated out to 10 years for ICD‐indicated patients. Results A cohort of 18,770 matched patients were identified; average age 65.5 ± 13.38 and 21.9% female. ICD patients had significantly less MRI imaging (0.23 0.70 SD vs. 0.00 0.08 SD, P < 0.0001) than nonimplant patients. Among patients with records of stroke/transient ischemic attack (TIA) (ICD 5%, nonimplant 4%) and accompanying diagnostic imaging, 44% of nonimplant patients underwent MRI vs. 1% of ICD patients (P < 0.0001). Forecast models estimated that 53% to 64% of ICD‐eligible patients may require an MRI within 10 years. Conclusion MRI utilization is lower in ICD patients compared to nonimplant patients, yet the burden of incident stroke/TIA, back, and joint pain suggests an unmet need for MR‐conditional devices. J.

    Abstract Background: Rehospitalizations are prevalent and associated with decreased quality of life. Although hospice has been advocated to reduce rehospitalizations, it is not known how area-level hospice utilization patterns affect rehospitalization risk. Objectives: The study objective was to examine the association between hospice enrollment, local hospice utilization patterns, and 30-day rehospitalization in Medicare patients. Methods: With a retrospective cohort design, 1,997,506 hospitalizations were assessed between 2005 and 2009 from a 5% national sample of Medicare beneficiaries. Local hospice utilization was defined using tertiles representing the percentage of all deaths occurring in hospice within each Hospital Service Area (HSA). Cox proportional hazard models were used to assess the relationship between 30-day rehospitalization, hospice enrollment, and local hospice utilization, adjusting for patient sociodemographics, medical history, and hospital characteristics. Results: Rates of patients dying in hospice were 27% in the lowest hospice utilization tertile, 41% in the middle tertile, and 53% in the highest tertile. Patients enrolled in hospice had lower rates of 30-day rehospitalization than those not enrolled (2.2% versus 18.8%; adjusted hazard ratio [HR], 0.12; 95% confidence interval [CI], 0.118–0.131). Patients residing in areas of low hospice utilization were at greater rehospitalization risk than those residing in areas of high utilization (19.1% versus 17.5%; HR, 1.05; 95% CI, 1.04–1.06), which persisted beyond that accounted for by individual hospice enrollment. Conclusions: Area-level hospice utilization is inversely proportional to rehospitalization rates. This relationship is not fully explained by direct hospice enrollment, and may reflect a spillover effect of the benefits of hospice extending to nonenrollees. PMID:25879990

    Stigma is a major social barrier that can restrict access to and willingness to seek psychiatric care. Psychiatric consumers may use secrecy and withdrawal in an attempt to cope with stigma. The purpose of this study was to determine the effects of music therapy on self- and experienced stigma in acute care psychiatric inpatients using a randomized design with wait-list control. Participants (N=83) were randomly assigned by cluster to one of three single-session group-based conditions: music therapy, education, or wait-list control. Participants in the music therapy and education conditions completed only posttests while participants in the wait-list control condition completed only pretests. The music therapy condition was a group songwriting intervention wherein participants composed lyrics for "the stigma blues." Results indicated significant differences in measures of discrimination (experienced stigma), disclosure (self-stigma), and total stigma between participants in the music therapy condition and participants in the wait-list control condition. From the results of this randomized controlled investigation, music therapy may be an engaging and effective psychosocial technique to treat stigma. Limitations, suggestions for future research, and implications for clinical practice and psychiatric music therapy research are provided.

    Hemodialysis patients in Japan are aging and thus more patients need support for attending hemodialysis facilities. This study aimed to clarify how dialysis patients utilize the services covered by Japan's public long-term care insurance (LTCI) system. This cross-sectional study was based on LTCI data of March 31, 2009, the latest available data provided by Niigata City, located on the northwest coast of Honshu. Among 30,349 LTCI users in Niigata City, there were 234 dialysis patients. To clarify the characteristics of the dialysis patients, we compared the utilization of LTCI services between the dialysis patients (234 users) and randomly selected 765 non-dialysis users. We also calculated the annual transportation service costs per patient for dialysis patients who continued home care (home care group) and those who switched to long-term hospital care at LTCI care levels 4 and 5 (hospital admission group). These care levels indicate difficulty in walking or maintaining a sitting posture without assistance. The dialysis group more frequently utilized home care and equipment services, such as renting or purchasing care-support products and support for home equipment repair, and utilized facility services and short-stay services (respite care) less frequently (both p < 0.001). Cost per patient was higher in the home care group than in the hospital admission group, because the transportation services for dialysis patients at care levels 4 and 5 involve higher costs. These findings indicate that LTCI services usable for dialysis patients were limited. Therefore, instead of merely subsidizing transportation expenses, transportation services must be improved.

    2011-01-01

    Background Patterns of healthcare utilization and costs in patients beginning pharmacotherapy for generalized anxiety disorder (GAD) have not been well characterized. Methods Using a large US health insurance database, we identified all patients with evidence of GAD (ICD-9-CM diagnosis code 300.02) who initiated pharmacotherapy with medications commonly used to treat GAD (eg, selective serotonin reuptake inhibitors [SSRIs], venlafaxine, benzodiazepines) between 1/1/2003 and 12/31/2007. We examined healthcare utilization and costs over the 12-month periods preceding and following date of initial receipt of such therapy ("pretreatment" and "follow-up", respectively). Patients with incomplete data were excluded. Results A total of 10,275 patients met all study inclusion criteria. Forty-eight percent of patients received SSRIs; 34%, benzodiazepines; and 6%, venlafaxine. SSRIs and venlafaxine were about three times more likely to be used on a long-term basis (> 90 days) than benzodiazepines (p < 0.01). In general, levels of healthcare utilization were higher during follow-up than pretreatment. Mean (SD) total healthcare costs increased from $4812 ($10,006) during pretreatment to $7182 ($22,041) during follow-up (p < 0.01); costs of GAD-related pharmacotherapy during follow-up were $420 ($485). Conclusions More than one-half of patients initiating pharmacotherapy for GAD receive either SSRIs or venlafaxine. Levels of healthcare utilization and costs are greater in the year following initiation of therapy than in the immediately preceding one. PMID:22151689

    This study aims to examine the associations between comorbid conditions and healthcare utilization, medical charges, or mortality of patients with rheumatoid arthritis (RA). Nebraska state emergency department (ED) discharge, hospital discharge, and death certificate data from 2007 to 2012 were used to study the comorbid conditions of patients with RA. RA was defined using the standard International Classification of Diseases (ICD-9-CM 714 or ICD-10-CM M05, M06, and M08). There were more comorbid conditions in patients with RA than in patients without RA. Comorbid conditions were majorly related to healthcare utilization and mortality of patients with RA. In addition to injury, fracture, sprains, and strains, symptoms of cardiovascular and digestive systems, respiratory infection, and chronic obstructive pulmonary disease (COPD) were common comorbid conditions for ED visits. In addition to joint replacement and fracture, infections, COPD and cardiovascular comorbidities were common comorbid conditions for hospitalizations. Cardiovascular, cerebrovascular, and respiratory comorbidities, dementia, malignant neoplasm, and diabetes mellitus were common comorbid conditions for deaths of patients with RA. In addition, the numbers of comorbid conditions were significantly associated with the length of hospital stay and hospital charges for patients with RA. The findings in this study indicated that comorbid conditions are associated with healthcare utilization, medical charges, and mortality of patients with RA. PMID:27106546

    Objective This study compared the preventive service utilization of uninsured patients receiving care at Oregon community health centers (CHCs) in 2008 through 2011 with that of continuously insured patients at the same CHCs in the same period, using electronic health record (EHR) data. Methods We performed a retrospective cohort analysis, using logistic mixed effects regression modeling to calculate odds ratios and rates of preventive service utilization for patients without insurance, or with continuous insurance. Results CHCs provided many preventive services to uninsured patients. Uninsured patients were less likely than continuously insured patients to receive 5 of 11 preventive services, ranging from OR 0.52 (95% CI: 0.35–0.77) for mammogram orders to 0.75 (95% CI: 0.66–0.86) for lipid panels. This disparity persisted even in patients who visited the clinic regularly. Conclusion Lack of insurance is a barrier to preventive service utilization, even in patients who can access care at a CHC. Policymakers in the United States should continue to address this significant prevention disparity. PMID:25124279

    Objective We reviewed the current literature regarding antiretroviral (ARV)-sparing therapy strategies to determine whether these novel regimens can be considered appropriate alternatives to standard regimens for the initial treatment of ARV-naive patients or as switch therapy for those patients with virologically suppressed HIV infection. Methods A search for studies related to HIV dual therapy published from January 2000 through April 2014 was performed using Biosis, Derwent Drug File, Embase, International Pharmaceutical Abstracts, Medline, Pascal, SciSearch, and TOXNET databases; seven major trial registries, and the abstracts of major conferences. Using predetermined criteria for inclusion, an expert review committee critically reviewed and qualitatively evaluated all identified trials for efficacy and safety results and potential limitations. Results Sixteen studies of dual therapy regimens were critiqued for the ARV-naive population. Studies of a protease inhibitor/ritonavir in combination with the integrase inhibitor raltegravir or the nucleoside reverse transcriptase inhibitor lamivudine provided the most definitive evidence supporting a role for dual therapy. In particular, lopinavir/ritonavir or darunavir/ritonavir combined with raltegravir and lopinavir/ritonavir combined with lamivudine demonstrated noninferiority to standard of care triple therapy after 48 weeks of treatment. Thirteen trials were critiqued in ARV-experienced, virologically suppressed patients. The virologic efficacy outcomes were mixed. Although overall data regarding toxicity are limited, when compared with standard triple therapy, certain dual therapy regimens may offer advantages in renal function, bone mineral density, and limb fat changes; however, some dual combinations may elevate lipid or bilirubin levels. Conclusions The potential benefits of dual therapy regimens include reduced toxicity, improved tolerability and adherence, and reduced cost. Although the data reviewed here

    Bortezomib therapy has become an important part of the standard of care for patients with relapsed multiple myeloma, and preliminary clinical evidence suggests that bortezomib retreatment in patients previously treated with the drug may prolong disease control. This retrospective study was designed to clarify the utility of bortezomib as a repeat therapy. We reviewed records from 3 major cancer centers that had participated in the phase II (SUMMIT or CREST) or phase III (APEX) registration studies to identify patients who were subsequently retreated off protocol with bortezomib-based therapy. We found 22 patients who received bortezomib retreatment following a 60 or more day gap between bortezomib treatments. Twelve patients had intervening therapy between initial bortezomib treatment and bortezomib retreatment. During retreatment, 14 of 22 patients received bortezomib in combination with another antineoplastic agent. The overall response rate for bortezomib retreatment was 50% (9% complete responses). The median length of retreatment was 5.1 months in responding patients and 2.4 months in nonresponding patients. Therapy was terminated due to unmanageable toxicity in 2 patients during retreatment, compared with 6 patients during initial treatment. During retreatment, no patients required dose reduction due to peripheral neuropathy, compared to 4 patients during their initial treatment. Thus, bortezomib retreatment appears to be safe and effective. Favorable observed response rates with bortezomib retreatment suggest that it may be a viable option for relapsed or refractory multiple myeloma, even in patients previously exposed to bortezomib.

Targeted selection of high-risk patients from an electronic database allows PCMH pharmacists to prioritize assessments. Trusting relationships between PCMH clinical pharmacists and primary care providers facilitates high response rates to pharmacist recommendations. This health system approach led by PCMH pharmacists provides a framework for proactive responses to FDA safety alerts and medication related quality measure improvement. PMID:27001101

    Purpose Cervical dystonia (CD) is a hypertonic condition caused by damage to the central nervous system. Very few studies have assessed the overall economic burden of the disease. The objective of this study was to describe the utilization of health care resources of patients with CD in the UK primary care setting, using a large population-based database. Patients and methods Adults with a first diagnosis of CD between January 1, 2007 and January 31, 2011, who were registered to a general practitioner (GP) practice contributing to The Health Improvement Network (THIN), were included. Sociodemographic and clinical characteristics were assessed at the time of diagnosis. Health care resource utilization and pharmacological treatment were investigated at the end of the first and second year after diagnosis. Results Overall, 4,024 newly diagnosed patients with CD were identified, with average age at diagnosis of 45 years old; 65.3% were female. Depression in the year prior to diagnosis was the most common comorbidity. Primary care utilization was high in the first year, with 99.2% of patients visiting their GP (on average 6.2 times), and 43% visiting a nurse (on average 2.5 times). Patients were most commonly referred to an orthopedic surgeon, and 15.9% reported at least one physiotherapy visit. In the second year, utilization was similar. Prescriptions of at least one of the investigated treatments were found in 82.0% and 45.3%, in the first and second year, respectively. Conclusion Findings suggest a high number of new CD cases are being identified in primary care, but not all will be referred to secondary care. Health care resource utilization was compared with that of all patients registered in THIN, which is representative of the UK, and the adjusted usage of primary care resources was found to be similar to that of the THIN population.

    Background: Patients with Crohn's disease in whom tumor necrosis factor antagonist therapy fails have limited treatment options, and the benefit of reintroducing the same therapy remains unclear. Here, we report results from PRECiSE 4 (NCT00160706), an open-label extension study of certolizumab pegol in patients who withdrew from the placebo-controlled studies PRECiSE 1 or 2. Methods: Patients eligible for PRECiSE 4 had Crohn's disease exacerbation on placebo or primary or secondary failure to certolizumab pegol in PRECiSE 1 or 2, and received 400 mg certolizumab pegol subcutaneously at weeks 0, 2, and 4 and every 4 weeks thereafter up to 360 weeks. We assessed safety (adverse events) and efficacy (clinical remission) of extended certolizumab pegol therapy. Results: Patients enrolled in PRECiSE 4 (N = 310; mean age, 37 yr; 58% female; 95% white) had a mean Crohn's disease duration of 8.5 years before entering the qualifying studies. At weeks 52, 104, and 156, remission rates were 28.5%, 17.5%, and 12.6% by nonremitter imputation, and 63.8%, 60.0%, and 63.5% by observed cases, with 47.4%, 31.9%, and 23.2% of patients, respectively, remaining on therapy. By study end (7.5 yr), 92.3% of patients discontinued therapy, 49% on account of adverse events. No new safety signals emerged. Incidence rate (new cases)/100 patient-years was 6.11 for serious infections and 1.29 for malignancies. Conclusions: Certolizumab pegol was effective in many patients who previously discontinued certolizumab pegol for lack or loss of response. Thus, discontinuation of therapy may not always be necessary. Safety was consistent with previous findings. PMID:27400222

    Periodontal health states are difficult to quantify and no formal scale quantifying patients' utilities for periodontal health states exits. Multi-attribute utility (MAU) techniques were used to develop such a scale. The MAU scale may be used to quantify patients' assessment of their current periodontal health and that of possible treatment outcomes. Such data, combined with probability values in formal decision analysis techniques would result in improved rationality of treatment planning for periodontal disease. 20 patients attending for routine undergraduate care were interviewed. Data from these interviews were sorted into groups of common interest (domains). Intra-domain health statements were complied from the interview content. 21 patients ranked the intra-domain statements on a scale of 0-100. This same group of patients also performed an inter-domain weighting. Mean results showed that patients were 2X as concerned with how they felt and with the prognosis of possible outcomes, than with how they looked and what facts they knew about their oral health. However, the real value of utilities research lies in application of individual results to treatment planning as there is a wide range of opinion regarding outcome health states. PMID:8891929

    Chronic low back pain (LBP) patients with radiculopathy, or sciatica, experience pain, tingling or numbness radiating down their leg due to compression of the lumbar nerve root. The resulting reduction in somatosensory information from the foot sole may contribute to deficits in standing balance control. This work was designed to investigate the relationship between foot skin sensitivity and standing balance control in chronic LBP patients with associated radiculopathy. Patients (n=9) and matched healthy controls (n=9) were recruited to the study, and were tested for balance control in both quiet standing as well as during rapid arm raise perturbation trials on a force plate. Foot skin sensitivity was tested bilaterally for vibratory threshold (3, 40 and 250 Hz) and touch (monofilament) threshold. Results demonstrate that patients had reduced sensitivity to 250 Hz vibration in their affected compared to unaffected foot (at the great toe and heel), as well as compared to controls (at the great toe), but there were no differences with lower frequency vibratory testing or with monofilament testing. While there were no significant between-group differences in balance measures, moderate statistically significant correlations between 250 Hz sensitivity and quiet standing balance parameters were uncovered. Thus, patients demonstrate reduced high-frequency vibratory sensitivity at the foot sole, and correlations with quiet standing balance measures indicate a connection between these foot skin sensitivity deficits and alterations in balance control. Clinically, this identifies high frequency vibration testing as an important measure of skin sensitivity in patients with radiculopathy.

  9. Aging, experienced nurses: their value and needs.

    The nursing workforce mirrors the trend in population; that is, it is aging. Subsequently, older nurses experiencing some aging effects themselves are caring for more elderly patients needing more assistance with illness and wellness problems. To meet the growing demand for care in this era of nursing shortage, predicted to last beyond 2020, these nurses are needed to remain in the workforce longer. Lack of nurses in the workplace compromises patient care and increases job stress. Therefore, retention incentives need to be implemented to assist aging, experienced nurses to delay retirement or prevent them from leaving the profession early, as well as encouraging younger and future nurses to work longer. This article focuses on aging nurses, describing their demographics and needs, explicating their value and listing the resources and benefits needed to prolong their vital services in the workforce. (For this article, aging, older and mature refer to experienced nurses in their 40s, 50s and 60s.). PMID:17563332

    As data on procalcitonin utility in antibiotics discontinuation [under an antimicrobial stewardship program (ASP)] in patients with malignancies are lacking, we aimed to evaluate the utility of procalcitonin in an ASP in patients with malignancies. We conducted a retrospective review of the ASP database of all patients with malignancies in whom at least one procalcitonin level was taken and our ASP had recommended changes in carbapenem regimen, from January to December 2011. We compared clinical outcomes between two groups of patients: patients whose physicians accepted and those whose physicians rejected ASP interventions. There were 749 carbapenem cases reviewed. Ninety-nine were suggested to either de-escalate, discontinue antibiotics, or narrow the spectrum of empiric treatment, based on procalcitonin trends. While there was no statistical difference in the mortality within 30 days post-ASP intervention (accepted: 8/65 patients vs. rejected: 9/34 patients; p = 0.076), the median duration of carbapenem therapy was significantly shorter (5 vs. 7 days; p = 0.002). Procalcitonin use safely facilitates decisions on antibiotics discontinuation and de-escalation in patients with malignancies in the ASP.

    Introduction Prolonged glucocorticoid use may increase the risk of adverse safety outcomes, including cardiovascular events. The European League Against Rheumatism and the Canadian Rheumatology Association advise tapering glucocorticoid dose as rapidly as clinically feasible. There is a paucity of published data on RA that adequately describe concomitant treatment patterns. Methods ACTION (AbataCepT In rOutiNe clinical practice) is a non-interventional cohort study of patients from Europe and Canada that investigated the long-term retention of intravenous abatacept in clinical practice. We assessed concomitant glucocorticoids in patients with established RA who had participated in ACTION and received ≥1 biological agent prior to abatacept initiation. Results The analysis included 1009 patients. Glucocorticoids were prescribed at abatacept initiation in 734 (72.7%) patients at a median 7.5 mg/day dose (n=692). Of the patients who remained on abatacept at 24 months, 40.7% were able to decrease their dose of glucocorticoids, including 26.9% who decreased their dose from >5 mg/day to ≤5 mg/day. Conclusion Reduction and/or cessation of glucocorticoid therapy is possible with intravenous abatacept in clinical practice. PMID:26925253

    Patients with single ventricle (SV) congenital heart disease (CHD) incur high hospital costs during staged surgical palliation. Health care resource utilization for noncardiac admissions in patients with SV has not been reported. This study sought to compare costs and outcomes for common noncardiac hospital admissions between patients with SV and patients without CHD. Hospital discharge data from the University Health System Consortium from January 2011 to December 2013 was queried for patients aged ≤18 years with International Classification of Diseases, Ninth Revision (ICD-9) codes for SV lesions: hypoplastic left heart syndrome (746.7), tricuspid atresia (746.1), or common ventricle (745.3). Primary diagnosis, direct cost, length of stay (LOS), intensive care unit admission rate and mortality data were obtained. The 10 most common noncardiac admission diagnoses were compared between patients with SV and patients without CHD using t test and Fisher's exact test. Total direct cost, LOS, and intensive care unit admission rate were higher for patients with SV for all diagnoses with the exception of LOS for dehydration, which was not different between groups. Hospital mortality was significantly higher for patients with SV admitted for acute kidney injury, esophageal reflux, failure to thrive, respiratory syncytial virus bronchiolitis and pneumonia. In conclusion, our study demonstrates that patients with SV CHD admitted with noncardiac diagnoses have higher health care resource utilization compared to those without CHD. As long-term survival increases, it can be expected that this patient group will use a disproportionate amount of medical dollars. Further characterization of costs will be important so steps can be taken to reduce or prevent hospitalization in these patients. PMID:27018934

    The aim of the study was to analyze the concordance of INR values obtained by educated lay users with those obtained by professionals and to determine the imprecision of the new system. The new CoaguChek XS system was tested in a user study over six weeks at four study centres in Austria, Denmark and Germany. Seventy-five patients receiving oral anticoagulant therapy were enrolled in the study. The INR results in capillary whole blood taken by professionals and by patients using the CoaguChek XS system were similar, and the mean relative bias was <1%. The imprecision of the CoaguChek XS system calculated from duplicate testing is low (<6%) and slightly better than for the established CoaguChek S system. The INR results measured during the home testing phase correlated quite well between the established CoaguChek S system and the new CoaguChek XS system with a mean bias of 0.14 INR. This is a remarkably low bias taking into consideration that more than 30 different test strip lots were applied. A questionnaire was filled out by all patients to assess their personal impression. It revealed that patients were very satisfied with the new system and found it easy to operate. The results demonstrate that the agreement between professional and patient INR results for the new CoaguChek XS system was excellent and that INR values can be determined by lay users as well as by professionals. The instrument is very well accepted by the patients and their satisfaction even increased after four weeks practice at home.

    Background: Lung cancer is associated with rapid disease progression, which can significantly progress over a duration of four to eight weeks. This study examines the time interval lung cancer patients from the interior of British Columbia (BC) experience while undergoing diagnostic evaluation, biopsy, staging, and preparation for treatment. Methods: A chart review of lung cancer patients (n=231) referred to the BC Cancer Agency Centre for the Southern Interior between January 1, 2010 and December 31, 2011 was performed. Time zero was defined as the date of the first abnormal chest imaging. Time intervals, expressed as median averages, to specialist consult, biopsy, oncologic referral, initial oncology consultation, and commencement of oncologic treatment were obtained. Results: The median time interval from first abnormal chest imaging to a specialist consultation was 18 days (interquartile range, IQR, 7-36). An additional nine days elapsed prior to biopsy in the form of bronchoscopy, CT-guided biopsy, or sputum cytology (median; IQR, 3-21); if lobectomy was required, 18 days elapsed (median; IQR, 9-28). Eight days were required for pathologic diagnosis and subsequent referral to the cancer centre (median; IQR, 3-16.5). Once referral was received, 10 days elapsed prior to consultation with either a medical or radiation oncologist (median, IQR 5-18). Finally, eight days was required for initiation of radiation and/or chemotherapy (median; IQR, 1-15). The median wait time from detection of lung cancer on imaging to oncologic treatment in the form of radiation and/or chemotherapy was 65.5 days (IQR, 41.5-104.3).  Interpretation: Patients in the BC Southern Interior experience considerable delays in accessing lung cancer care. During this time, the disease has the potential to significantly progress and it is possible that a subset of patients may lose their opportunity for curative intent treatment. PMID:26543688

    In this short communication we present a re-analysis of homeopathic patient data in comparison to control patient data from the same Outpatient´s Unit "Homeopathy in malignant diseases" of the Medical University of Vienna. In this analysis we took account of a probable immortal time bias. For patients suffering from advanced stages of cancer and surviving the first 6 or 12 months after diagnosis, respectively, the results show that utilizing homeopathy gives a statistically significant (p<0.001) advantage over control patients regarding survival time. In conclusion, bearing in mind all limitations, the results of this retrospective study suggest that patients with advanced stages of cancer might benefit from additional homeopathic treatment until a survival time of up to 12 months after diagnosis.

    Introduction In health economic evaluations, mapping can be used to estimate utility values from other health outcomes in order to calculate quality adjusted life-years. Currently, no methods exist to map visual analog scale (VAS) scores to utility values. This study aimed to develop and propose a statistical algorithm for mapping five dimensions of health, measured on VASs, to utility scores in patients suffering from cardiovascular disease. Methods Patients undergoing coronary artery bypass grafting at Aalborg University Hospital in Denmark were asked to score their health using the five VAS items (mobility, self-care, ability to perform usual activities, pain, and presence of anxiety or depression) and the EuroQol 5 Dimensions questionnaire. Regression analysis was used to estimate four mapping models from patients’ age, sex, and the self-reported VAS scores. Prediction errors were compared between mapping models and on subsets of the observed utility scores. Agreement between predicted and observed values was assessed using Bland–Altman plots. Results Random effects generalized least squares (GLS) regression yielded the best results when quadratic terms of VAS scores were included. Mapping models fitted using the Tobit model and censored least absolute deviation regression did not appear superior to GLS regression. The mapping models were able to explain approximately 63%–65% of the variation in the observed utility scores. The mean absolute error of predictions increased as the observed utility values decreased. Conclusion We concluded that it was possible to predict utility scores from VAS scores of the five dimensions of health used in the EuroQol questionnaires. However, the use of the mapping model may be inappropriate in more severe conditions. PMID:24453497

    Purpose Aims of this study were to identify aspects of functioning and health relevant to patients with vertigo expressed by ICF categories and to explore the potential of the ICF to describe the patient perspective in vertigo. Methods We conducted a series of qualitative semi-structured face-to-face interviews using a descriptive approach. Data was analyzed using the meaning condensation procedure and then linked to categories of the International Classification of Functioning, Disability and Health (ICF). Results From May to July 2010 12 interviews were carried out until saturation was reached. Four hundred and seventy-one single concepts were extracted which were linked to 142 different ICF categories. 40 of those belonged to the component body functions, 62 to the component activity and participation, and 40 to the component environmental factors. Besides the most prominent aspect “dizziness” most participants reported problems within “Emotional functions (b152), problems related to mobility and carrying out the daily routine. Almost all participants reported “Immediate family (e310)” as a relevant modifying environmental factor. Conclusions From the patients’ perspective, vertigo has impact on multifaceted aspects of functioning and disability, mainly body functions and activities and participation. Modifying contextual factors have to be taken into account to cover the complex interaction between the health condition of vertigo on the individuals’ daily life. The results of this study will contribute to developing standards for the measurement of functioning, disability and health relevant for patients suffering from vertigo. PMID:22738067

    Background: Health services for those in need. Inpatient care shows a more serious side of individual care and patients and their family members perceive a high level of stress and urge. We conducted this study to determine inequalities of in-patient health care utilization in Iranian people and to assess factors that influence utilization. Methods: In each province, the sample was comprised of 380 urban and 380 rural households that were recruited by a systematic random sampling method. A total of 23,560 households, which included around 102,000 individuals were recruited. We used the questionnaire for data collection. Met admission need (MAN) was the main variable and was considered household assets for determining the economic status. We did all analyses using the STATA version 9.1. Results: The rates of MAN for urban and rural areas were 83% and 81.3% respectively. The rate of MAN was significantly higher in patients with higher educational level. Patients with primary health insurance coverage had significantly higher rate of MAN. Conclusions: Meeting admission needs was estimated around 84% and it seems that modifying insurance coverage is the most feasible intervention for increasing utilization of health services.

    Tumor genomic instability and selective treatment pressures result in clonal disease evolution; molecular stratification for molecularly targeted drug administration requires repeated access to tumor DNA. We hypothesized that circulating plasma DNA (cpDNA) in advanced cancer patients is largely derived from tumor, has prognostic utility, and can be utilized for multiplex tumor mutation sequencing when repeat biopsy is not feasible. We utilized the Sequenom MassArray System and OncoCarta panel for somatic mutation profiling. Matched samples, acquired from the same patient but at different time points were evaluated; these comprised formalin-fixed paraffin-embedded (FFPE) archival tumor tissue (primary and/or metastatic) and cpDNA. The feasibility, sensitivity, and specificity of this high-throughput, multiplex mutation detection approach was tested utilizing specimens acquired from 105 patients with solid tumors referred for participation in Phase I trials of molecularly targeted drugs. The median cpDNA concentration was 17 ng/ml (range: 0.5-1600); this was 3-fold higher than in healthy volunteers. Moreover, higher cpDNA concentrations associated with worse overall survival; there was an overall survival (OS) hazard ratio of 2.4 (95% CI 1.4, 4.2) for each 10-fold increase in cpDNA concentration and in multivariate analyses, cpDNA concentration, albumin, and performance status remained independent predictors of OS. These data suggest that plasma DNA in these cancer patients is largely derived from tumor. We also observed high detection concordance for critical 'hot-spot' mutations (KRAS, BRAF, PIK3CA) in matched cpDNA and archival tumor tissue, and important differences between archival tumor and cpDNA. This multiplex sequencing assay can be utilized to detect somatic mutations from plasma in advanced cancer patients, when safe repeat tumor biopsy is not feasible and genomic analysis of archival tumor is deemed insufficient.

    Now that New Jersey has become the 14th state in the United States to enact legislation regarding dense breast screening, its patients are eligible to receive screening breast sonography coverage from their insurance carriers. This law is intended to improve breast cancer detection in patients with dense breasts and create awareness of unique issues that come with dense breast tissue, while reinforcing already present efforts to reduce the incidence of and morbidity related to the diagnosis of breast cancer. The aim of this study was to examine data from months preceding the effective date of this legislation in a community hospital setting and compare these data with data from months immediately after, and 6 months after, its enactment to present patient participation data and estimate the legislation's direct financial ramifications. Detractors of this type of legislation worry about overburdening the health care system with an influx of patients. Although there is a lack of present studies confirming this suspicion in other states with dense breast legislation, this study confirms a large increase in patient utilization after enactment, showing a minimum relative increase of 176.90% and a maximum relative increase of 335.56% in patient utilization of screening breast sonography. The investigators further include an estimation of an increased direct cost for insurers of $4,910,899.18 to $9,848,897.96 for a given month.

    An extension course for nurses providing details about the Act on the Protection of Personal Information was offered using a remote conferencing system. Experiences or problems related to disclosure of patient data were collected from the participants using a questionnaire. Most of the problems were placed in the category of disclosure of personal data to a third party, followed by those related to security safeguards and administration of employees. It is necessary for the JMHLW to gather more cases in order to expand the number of items in the Casebook by JMHLW. Also, systematic on-the-job education will be needed for nurses.

    Objective To compare the investigator assessment of patient risk for prescription opioid misuse, abuse, and diversion with patient self-reports of these activities in a population with chronic pain. Methods As a secondary objective of an open-label, multicenter, primary care-based clinical study to evaluate the success of converting opioid-experienced patients with chronic pain to morphine sulfate with sequestered naltrexone hydrochloride, risk for misuse, abuse, and diversion was assessed using two nonvalidated questionnaires: one was completed by the investigator and another by the patient (Self-Reported Misuse, Abuse, and Diversion [SR-MAD]). In addition, the validated Current Opioid Misuse Measure (COMM) test and urine drug test were used. Results Of the 684 patients assessed by the investigators, 537 returned the self-assessment, SR-MAD. Most patients were assigned by the investigator as low risk for misuse (84.2%), abuse (89.3%), and diversion (94.3%). Of the patients who returned SR-MAD, 60% indicated having taken more opioids than prescribed and 10.9% reported chewing or crushing their opioids in the past. Of the patients who completed COMM, 40.6% were deemed as having aberrant behaviors. COMM results correlated with the risk levels from the investigator assessment. One-third of patients (33.8%) had at least one abnormal urine drug test result. Conclusion More research is needed to better understand the gap between the investigator assessment of potential risk for misuse, abuse, and diversion and the actual extent of these behaviors among patients with chronic pain.

    Background Community-based and institutional dementia care has been compared in cross-sectional studies, but longitudinal information on the effect of institutionalization on health care service utilization is sparse. Methods We analyzed claims data from 651 dementia patients via Generalized Estimation Equations to assess health care service utilization profiles and corresponding expenditures from four quarters before to four quarters after institutionalization. Results In all domains, utilization increased in the quarter of institutionalization. Afterwards, the use of drugs, medical aids, and non-physician services (e.g., occupational therapy and physiotherapy) remained elevated, but use of in- and outpatient treatment decreased. Cost of care showed corresponding profiles. Conclusion Institutional dementia care seems to be associated with an increased demand for supportive services but not necessarily for specialized medical care. PMID:25337076

    OBJECTIVE The movement for advance planning of end-of-life care was motivated in part by the assumption that medical intervention for terminally ill patients varies from what these patients would prefer. We examined the validity of this assumption by comparing actual life-sustaining treatment practices for patients in critical illness scenarios and surveyed patients' advance care preferences. MEASUREMENTS AND MAIN RESULTS We selected at random and reviewed 7,400 inpatient medical records from a single urban teaching hospital during the period just prior to the Patient Self-Determination Act. Records of 198 patients with conditions that matched advance directive scenarios were examined, and practices to withhold or withdraw seven life-sustaining treatments were documented. Practices were compared with surveyed preferences of 102 members of the general public and 495 outpatients who were followed by the same physicians as the 198 patients. Concordance of practices and preferences for the 19 surveyed outpatients who eventually fell into one of the scenarios was also evaluated. One hundred sixty-seven inpatient cases met review criteria for the scenario coma with a small chance of recovery. Hospital patients received medical interventions that were not consistently greater or less than the preferences of the surveyed outpatients or members of the general public. Resuscitation, the most frequently withheld treatment (94% of cases), was withheld more often than surveyed preferences to decline it (56% of outpatients, p < .001). Four treatments—mechanical breathing, artificial nutrition, major surgery, and hemodialysis—were utilized comparably to surveyed outpatients' preferences (range p=.704 –.055). Antibiotics and artificial hydration were withheld (9% and 6%, respectively) less often than surveyed outpatient's prior preferences to decline them (48% and 52%, respectively, p < .001 for each). Conversely, treatments given to the 19 surveyed patients who subsequently

    Urinary tract infection (UTI) is one of the most common infections in children. Urine culture remains the gold standard for diagnosis, but the utility of urine Gram stain relative to urinalysis (UA) is unclear. We reviewed 312 pediatric patients with suspected UTI who had urine culture, UA, and urine Gram stain performed from a single urine specimen. UA was considered positive if ≥10 leukocytes per oil immersion field were seen or if either nitrates or leukocyte esterase testing was positive. Urine Gram stain was considered positive if any organisms were seen. Sensitivity, specificity, and positive and negative predictive values were calculated using urine culture as the gold standard. Thirty-seven (12%) patients had a culture-proven UTI. Compared to urine Gram stain, UA had equal sensitivity (97.3% versus 97.5%) and higher specificity (85% versus 74%). Empirical therapy was prescribed before the Gram stain result was known in 40 (49%) patients and after in 42 (51%) patients. The antibiotics chosen did not differ between the two groups (P=0.81), nor did they differ for patients with Gram-negative rods on urine Gram stain compared to those with Gram-positive cocci (P=0.67). From these data, we conclude that UA has excellent negative predictive value that is not enhanced by urine Gram stain and that antibiotic selection did not vary based on the urine Gram stain result. In conclusion, the clinical utility of urine Gram stain does not warrant the time or cost it requires.

    BACKGROUND Tracheostomy practice in patients with acute respiratory failure (ARF) varies greatly among institutions. This variability has the potential to be reflected in the resources expended providing care. In various healthcare environments, increased resource expenditure has been associated with a favorable effect on outcome. OBJECTIVE To examine the association between institutional resource expenditure and mortality in ARF patients managed with tracheostomy. METHODS We developed analytic models employing the University Health Systems Consortium (Oakbrook, Illinois) database. Administrative coding data were used to identify patients with the principal diagnosis of ARF, procedures, complications, post-discharge destination, and survival. Mean resource intensity of participating academic medical centers was determined using risk-adjusted estimates of costs. Mortality risk was determined using a multivariable approach that incorporated patient-level demographic and clinical variables and institution-level resource intensity. RESULTS We analyzed data from 44,124 ARF subjects, 4,776 (10.8%) of whom underwent tracheostomy. Compared to low-resource-intensity settings, treatment in high-resource-intensity academic medical centers was associated with increased risk of mortality (odds ratio 1.11, 95% CI 1.05–1.76), including those managed with tracheostomy (odds ratio high-resource-intensity academic medical center with tracheostomy 1.10, 95% CI 1.04 –1.17). We examined the relationship between complication development and outcome. While neither the profile nor number of complications accumulated differed comparing treatment environments (P > .05 for both), mortality for tracheostomy patients experiencing complications was greater in high-resource-intensity (95/313, 30.3%) versus low-resource-intensity (552/2,587, 21.3%) academic medical centers (P < .001). CONCLUSIONS We were unable to demonstrate a positive relationship between resource expenditure and outcome in

    In this study, we evaluated the clinical utility of detecting KRAS mutations in circulating cell-free (ccf)DNA of metastatic colorectal cancer patients. We prospectively recruited 94 metastatic colorectal cancer patients. Circulating cell-free DNA was extracted from plasma samples and analyzed for the presence of seven KRAS point mutations. Using the Invader Plus assay with peptide nucleic acid clamping method and digital PCR, KRAS mutations were detected in the ccfDNA in 35 of 39 patients previously determined to have primary tumors containing KRAS mutations using the Luminex method, and in 5 of 55 patients with tumors containing wild-type KRAS. Curative resection was undertaken in 7 of 34 patients with primary and ccfDNA KRAS mutations, resulting in the disappearance of the mutation from the cell-free DNA in five of seven patients. Three of these patients had tumor recurrence and KRAS mutations in their ccfDNA reappeared. Epidermal growth factor receptor blockade was administered to 24 of the KRAS tumor wild-type patients. Of the 24 patients with wild-type KRAS in their primary tumors, three patients had KRAS mutations in their ccfDNA and did not respond to treatment with epidermal growth factor receptor (EGFR) blockade. We also detected a new KRAS mutation in five patients during chemotherapy with EGFR blockade, before disease progression was detectable with imaging. The detection of KRAS mutations in ccfDNA is an attractive approach for predicting both treatment response and acquired resistance to EGFR blockade, and for detecting disease recurrence.

    The main goal of current pain management approaches is to increase the patients' quality of life by improving pain coping skills and by reducing the levels of disability in daily life, often despite persistent pain. Direct measurement of quality of life is of crucial importance in economic evaluation research, in which not only is the estimation of financial costs and benefits included, but so is the evaluation of costs and benefits in terms of changes in health states. The purpose of this study is to compare the psychometric qualities of two instruments for assessing patients' utilities, the rating scale (RS) and the standard gamble (SG). Such instruments are designed for their application in economic evaluation research, but have seldomly been used in chronic pain trials. Both methods provide a single measure between 0 and 1. The relationship between these utility measures and descriptive and domain-specific quality of life measures was examined in 133 fibromyalgia patients and 148 patients with chronic non-specific low back pain. Mean utility score at baseline was 0.43 with the RS and 0.78 for the SG. The correlation between both methods was found to be poor (r = 0.21). Both measures appeared to be fairly stable in a 2-week test-retest period (intra class correlation coefficient (ICC) = 0.74 and 0.77). Scores on the description of patient's own health on six domains, global assessment of change and domain specific measures correlated moderately with the RS scores and low with the SG. Multiple regression analyses demonstrated that 32% of the variance in RS values and only 13% of the variance in SG utilities could be explained by domain-specific measures. These results suggest an acceptable construct validity for the RS but insufficient construct validity for the SG. Valuations of ones own health appear only partially to be related to the assessment of the pain-specific measures and measures of distress. It can be concluded that the RS and domain-specific measures

    Objective To evaluate the impact of lung function, measured as forced expiratory volume in 1 second (FEV1) % predicted, on health care resource utilization and costs among patients with COPD in a real-world US managed-care population. Methods This observational retrospective cohort study utilized administrative claim data augmented with medical record data. The study population consisted of patients with one or more medical claims for pre- and postbronchodilator spirometry during the intake period (July 1, 2012 to June 30, 2013). The index date was the date of the earliest medical claim for pre- and postbronchodilator spirometry. Spirometry results were abstracted from patients’ medical records. Patients were divided into two groups (low FEV1% predicted [,50%] and high FEV1% predicted [≥50%]) based on the 2014 Global Initiative for Chronic Obstructive Lung Disease report. Health care resource utilization and costs were based on the prevalence and number of discrete encounters during the 12-month postindex follow-up period. Costs were adjusted to 2014 US dollars. Results A total of 754 patients were included (n=297 low FEV1% predicted group, n=457 high FEV1% predicted group). COPD exacerbations were more prevalent in the low FEV1% predicted group compared with the high group during the 12-month pre- (52.5% vs 39.6%) and postindex periods (49.8% vs 36.8%). Mean (standard deviation) follow-up all-cause and COPD-related costs were $27,380 ($38,199) and $15,873 ($29,609) for patients in the low FEV1% predicted group, and $22,075 ($28,108) and $10,174 ($18,521) for patients in the high group. In the multivariable analyses, patients in the low FEV1% predicted group were more likely to have COPD exacerbations and tended to have higher COPD-related costs when compared with patients in the high group. Conclusion Real-world data demonstrate that patients with COPD who have low FEV1% predicted levels use more COPD medications, have more COPD exacerbations, and incur higher

    We present data from our clinical department's experience with chromosomal microarray analysis (CMA) regarding the diagnostic utility of 1 or 2 long contiguous stretches of homozygosity (LCSHs) in an outbred population. The study group consisted of 2,110 consecutive patients from 2011 to 2014 for whom CMA was performed. The minimum cut-off size for defining a homozygous stretch was 5 Mb. To focus on cases with no parental consanguinity, we further studied only patients in whom the total length of homozygous stretches did not exceed 28 Mb or 1% of the autosomal genome length. We identified 6 chromosomal regions where homozygous stretches appeared in at least 3 patients and excluded these from further analysis. In 2 out of 120 patients with an isolated finding of 1 or 2 non-recurrent LCSHs, a plausible candidate gene associated with their phenotype was identified within the homozygous stretch. In both of these cases, a pathogenic mutation was detected, leading to diagnoses of pyruvate kinase deficiency and Marinesco-Sjögren syndrome. To clarify whether previously found homozygous stretches could be important for the interpretation of genome-wide sequencing data, we report 7 cases in which homozygous stretches not encompassing a clinically associated gene were first found on CMA, followed by the diagnostic whole-exome sequencing. The diagnostic utility of single LCSHs, unlikely to be caused by uniparental disomy, is discussed in detail. PMID:26733775

    OBJECTIVES: To determine population size, demographic characteristics, hospital utilization patterns, the specialties of physicians providing care, and costs for hospitalized adult sickle cell patients in Illinois. METHODS: A statewide, administrative dataset for the two-year period from january 1992 through December 1993 was analyzed retrospectively. RESULTS: There were 8403 admissions among 1189 individual sickle cell patients for the two-year period. Eighty-five percent of patients resided in the Chicago metropolitan area. The median age of the 1189 patients was 29; two-thirds had Medicaid or Medicare coverage. Emergency departments were the primary source of admissions (85.7%). The most common admitting diagnosis was painful crisis (97.4%), and average length of stay was four days. The median number of admissions per patient was three; most patients (85%) used only one or two hospitals. A small group used more than four hospitals and accounted for 23% of statewide admissions. Primary care physicians cared for most patients, and total hospitalization charges were more than $59 million. CONCLUSIONS: In Illinois the adult sickle cell population is concentrated in major urban centers, primarily the Chicago metropolitan area. These patients accounted for approximately 8400 admissions and more than $59 million in hospital charges during the two-year study period. A small group of patients used multiple hospitals and accounted for more than 23% of total hospitalization charges. This study shows the necessity of and provides a useful framework for developing targeted programs for adult sickle cell patients as well as for training physicians to efficiently provide comprehensive health care services for this population.

    Background Neuroimaging techniques have been beneficial in identifying patients with salvageable penumbra. We sought to validate the mean transit time (MTT) map on computed tomography perfusion (CTP) imaging utilizing an Aquilion ONE computed tomography (CT) scanner running a singular value decomposition plus algorithm in patients with acute large vessel ischemic stroke who underwent endovascular therapy. Methods We conducted a retrospective analysis of consecutive patients presenting to the emergency room who met the following criteria: 1) had a large vessel acute ischemic stroke; 2) had a high-quality whole-brain CTP; 3) treated with endovascular therapy; and 4) received a follow-up MRI with diffusion-weighted imaging (DWI) within 48 h. A blinded neurologist, neuroradiologist, and neurosurgeon utilized the Vitrea software to process the images independently using an infarct perimeter method. Results Twelve patients met the inclusion criteria. A comparison was made between the volumes of infarct core (IC) utilizing MTT and DWI after accounting for other co-founding factors (i.e., recanalization rate, time between CT and MRI, time to achieve recanalization, and IV t-PA administration). MTT was redefined as capillary MTT (cMTT) which represented evolving capillary flow influenced by hypoxia induced vasodilation/vasoconstriction. We divided the patients into two groups based on the degree of reperfusion: A) patients with a TICI score of IIb or III and B) patients with a TICI score of I or IIa. We compared the two groups and found that the rate of reperfusion significantly affected the volume of the infarct on MTT when compared with a follow-up MRI (p value < 0.04). Furthermore, we found a strong positive correlation R2 = 0.6 between the average MTT infarct volume and the final DWI MR volumes. In addition, the averaged MTT IC volumes were 84% of the final averaged DWI IC volumes. Conclusion Although further studies are required to validate this retrospective study

    2013-01-01

    Background A variety of instruments are used to measure health related quality of life. Few data exist on the performance and agreement of different instruments in a depressed population. The aim of this study was to investigate agreement between, and suitability of, the EQ-5D-3L, EQ-5D Visual Analogue Scale (EQ-5D VAS), SF-6D and SF-12 new algorithm for measuring health utility in depressed patients. Methods The intraclass correlation coefficient (ICC) and Bland and Altman approaches were used to assess agreement. Instrument sensitivity was analysed by: (1) plotting utility scores for the instruments against one another; (2) correlating utility scores and depressive symptoms (Beck Depression Inventory (BDI)); and (3) using Tukey’s procedure. Receiver Operating Characteristic (ROC) analysis assessed instrument responsiveness to change. Acceptability was assessed by comparing instrument completion rates. Results The overall ICC was 0.57. Bland and Altman plots showed wide limits of agreement for each pair wise comparison, except between the SF-6D and SF-12 new algorithm. Plots of utility scores displayed ’ceiling effects’ in the EQ-5D-3L index and ’floor effects’ in the SF-6D and SF-12 new algorithm. All instruments showed a negative monotonic relationship with BDI, but the EQ-5D-3L index and EQ-5D VAS could not differentiate between depression severity sub-groups. The SF-based instruments were better able to detect changes in health state over time. There was no difference in completion rates of the four instruments. Conclusions There was a lack of agreement between utility scores generated by the different instruments. According to the criteria of sensitivity, responsiveness and acceptability that we applied, the SF-6D and SF-12 may be more suitable for the measurement of health related utility in a depressed population than the EQ-5D-3L, which is the instrument currently recommended by NICE.

    2015-01-01

    Induction of labor is one of the most commonly performed obstetric procedures and will likely become more common as the reproductive population in developed nations changes. As the proportion of women undergoing induction grows, there is a constant search for more efficacious ways to induce labor while maintaining fetal and maternal safety as well as patient satisfaction. With almost half of induced labors requiring cervical ripening, methods for achieving active labor and vaginal delivery are constantly being investigated. Prostaglandins have been shown to be effective induction agents, and specifically vaginal misoprostol, used off-label, have been widely utilized to initiate cervical ripening and active labor. The challenge is to administer this medication accurately while maintaining the ability to discontinue the medication when needed. The misoprostol vaginal insert initiates cervical ripening utilizing a delivery system that controls medication release and can be rapidly removed. This paper reviews the design, development, and clinical utility of the misoprostol vaginal insert for induction of labor as well as patient considerations related to the delivery system.

    This article defines and describes best practices for the academic and business community to generate evidence of clinical utility for cancer molecular diagnostic assays. Beyond analytical and clinical validation, successful demonstration of clinical utility involves developing sufficient evidence to demonstrate that a diagnostic test results in an improvement in patient outcomes. This discussion is complementary to theoretical frameworks described in previously published guidance and literature reports by the U.S. Food and Drug Administration, Centers for Disease Control and Prevention, Institute of Medicine, and Center for Medical Technology Policy, among others. These reports are comprehensive and specifically clarify appropriate clinical use, adoption, and payer reimbursement for assay manufacturers, as well as Clinical Laboratory Improvement Amendments-certified laboratories, including those that develop assays (laboratory developed tests). Practical criteria and steps for establishing clinical utility are crucial to subsequent decisions for reimbursement without which high-performing molecular diagnostics will have limited availability to patients with cancer and fail to translate scientific advances into high-quality and cost-effective cancer care.

    Nonadherence to antipsychotic medications is widespread and compromises the outcome of patients with schizophrenia. Using the MarketScan Medicare claims database, this study examined the impact of medication adherence on healthcare utilization among Medicare insured schizophrenia patients. The study population was separated into two cohorts defined by medication adherence, one with a medication possession ratio (MPR) ≥0.7 (high adherence) and the other with a MPR <0.7(low adherence). Of the 354 patients identified, 126 (36 %) had high adherence (mean ± SD MPR 0.94 ± 0.09) and 228 (64 %) had low adherence (MPR 0.24 ± 0.19). All cause hospitalizations (0.68 vs. 0.44; p = 0.015) and length of stay (LOS) (7.0 vs. 2.6 days; p = 0.005), and relapse hospitalizations (0.22 vs. 0.11; p = 0.028) and LOS (3.2 vs. 0.7 days; p = 0.027) were greater among patients with low adherence. Low adherent Medicare insured patients with schizophrenia require significantly more inpatient care and represent a patient population in which effective interventions are needed to improve disease management.

    Facioscapulohumeral dystrophy (FSHD) is a rare inherited neuromuscular disease estimated to affect 1/15,000 people. Through basic research, remarkable progress has been made towards the development of targeted therapies. Patient identification, through registries or other means is essential for trial-readiness. The UK FSHD Patient Registry is a patient initiated registry that collects standardised and internationally agreed dataset of self-reported clinical details combined with professionally verified genetic information. It includes four additional questionnaires to capture patient reported outcomes related to pain, quality of life and scapular fixation. Between 2013 and 2015, 518 patients registered 243 males, 241 females with a mean age of 47.8 years. Most of the patients have FSHD type 1 (91.7 %), and weakness of the facial (59.2 %) was the most prevalent symptom at onset, followed by shoulder-girdle muscles (53.3 %) and distal (22.45 %) or proximal lower limb weakness (14.8 %). 85.57 % patients were ambulant or ambulant with assistance at the time of registration, 7.9 % report respiratory insufficiency. The registry has demonstrated utility with the recruitment of patients for a natural history study of infantile onset FSHD, and the longitudinal analysis of patient-related outcomes will provide much-needed baseline information to power future trials. The internationally agreed core dataset enables national registries to participate in a "Global FSHD registry". We suggest that the registry's ability to interoperate with other large datasets will be instrumental for sharing and exploiting data globally. PMID:27159994

    Kabuki syndrome (KS) is a dominantly inherited disorder mainly due to de novo pathogenic variation in KMT2D or KDM6A genes. Initially, a representative cohort of 14 Czech cases with clinical features suggestive of KS was analyzed by experienced clinical geneticists in collaboration with other specialties, and observed disease features were evaluated according to the 'MLL2-Kabuki score' defined by Makrythanasis et al. Subsequently, the aforementioned genes were Sanger sequenced and copy number variation analysis was performed by MLPA, followed by genome-wide array CGH testing. Pathogenic variants in KMT2D resulting in protein truncation in 43% (6/14; of which 3 are novel) of all cases were detected, while analysis of KDM6A was negative. MLPA analysis was negative in all instances. One female patient bears a 6.6 Mb duplication of the Xp21.2-Xp21.3 region that is probably disease causing. Subjective KS phenotyping identified predictive clinical features associated with the presence of a pathogenic variant in KMT2D. We provide additional evidence that this scoring approach fosters prioritization of patients prior to KMT2D sequencing. We conclude that KMT2D sequencing followed by array CGH is a diagnostic strategy with the highest diagnostic yield. PMID:26841933

    OBJECTIVE. This study describes demographic characteristics of pediatric AIDS patients, describes hospital and community-based service utilization patterns, and analyzes medical and social support service usage patterns with respect to patient demographic characteristics, clinical trial participation, functional/developmental status, and social environment. DATA SOURCES AND STUDY SETTING. Data reported in this study are from the AIDS Costs and Service Utilization Survey (ACSUS) and cover the six-month period beginning March 1991 (N = 135). Pediatric patients who sought care for HIV-related problems were sampled at seven different hospitals in five metropolitan regions of the United States. All of the participating hospitals had clinics specifically serving pediatric patients infected with HIV. The sample consists of HIV-positive patients who had had at least one HIV-related symptom or condition. STUDY DESIGN. A stratified probability sample design guided the sampling strategy, which included oversampling in two large hospitals from two of the five metropolitan areas. Survey data cover an 18-month time period of health care utilization, cost, and financing information from HIV-infected patients and their providers. Utilization measures are standardized to a six-month period. Per capita income, family structure, informal personal network, functional status, and clinical trial participation are tested for associations with patterns of utilization. In addition, a weighted ten-point social severity scale was developed to assess family/household stability. DATA COLLECTION. Data were collected through a screener instrument completed by the person accompanying the child to a hospital clinic visit (usually a a parent), and through two interviews conducted in person with the patients' primary caregivers. Data from the questionnaires were coded and assembled into computerized SAS analysis files by WESTAT. PRINCIPAL FINDINGS. Children in this sample are 62 percent African

    Patients with upper gastrointestinal (GI) bleeding frequently require hospitalization and have a mortality rate that ranges from 6% to 14%. These patients need rapid clinical assessment to determine the urgency of endoscopy and the need for endoscopic treatment. Risk-scoring tools, such as the Rockall score and the Glasgow-Blatchford score, are commonly used in this assessment. These tools clearly help identify high-risk patients but do not necessarily have good predictive value in identifying important outcomes. Their diagnostic accuracy in identifying rebleeding and mortality ranges from poor to fair. The shock index (heart rate divided by systolic blood pressure) provides an integrated assessment of the cardiovascular status. It can be easily calculated during the initial evaluation of patients and monitoring after treatment. The shock index has been used in a few studies in patients with acute GI bleeding, including studies to determine which patients need emergency endoscopy, to predict complications after corrosive ingestions, to identify delayed hemorrhage following pancreatic surgery, and to evaluate the utility of angiograms to identify sites of GI bleeding. Not all studies have found the shock index to be useful in patients with GI bleeding, however. This may reflect the unpredictable natural history of various etiologies of GI bleeding, comorbidity that may influence blood pressure and/or heart rate, and inadequate data acquisition. The shock index needs more formal study in patients with GI bleeding admitted to medical intensive care units. Important considerations include the initial response to resuscitation, persistent bleeding following initial treatment, and rebleeding following a period of stabilization. In addition, it needs correlation with other risk-scoring tools. PMID:26954657

  7. Resource utilization in patients with schizophrenia who initiated risperidone long-acting therapy: results from the Schizophrenia Outcomes Utilization Relapse and Clinical Evaluation (SOURCE)

    Background Schizophrenia is a chronic mental health disorder associated with increased hospital admissions and excessive utilization of outpatient services and long-term care. This analysis examined health care resource utilization from a 24-month observational study of patients with schizophrenia initiated on risperidone long-acting therapy (RLAT). Methods Schizophrenia Outcomes Utilization Relapse and Clinical Evaluation (SOURCE) was a 24-month observational study designed to examine real-world treatment outcomes by prospectively following patients with schizophrenia initiated on RLAT. At baseline visit, prior hospitalization and ER visit dates were obtained for the previous 12 months and subsequent hospitalization visit dates were obtained at 3-month visits, if available. The health care resource utilization outcomes measures observed in this analysis were hospitalizations for any reason, psychiatric-related hospitalizations, and emergency room (ER) visits. Incidence density analysis was used to assess pre-event and postevent rates per person-year (PY). Results The primary medical resource utilization analysis included 435 patients who had a baseline visit, ≥1 postbaseline visits after RLAT initiation, and valid hospitalization dates. The number of hospitalizations and ER visits per PY declined significantly (p < .0001) after initiation with RLAT. A 41% decrease (difference of -0.29 hospitalizations per PY [95% CI: -0.39 to -0.18] from baseline) in hospitalizations for any reason, a 56% decrease (a difference of -0.35 hospitalizations per PY [95% CI: -0.44 to -0.26] from baseline) in psychiatric-related hospitalizations, and a 40% decrease (-0.26 hospitalizations per PY [95% CI: -0.44 to -0.10] from baseline) in ER visits were observed after the baseline period. The percentage of psychiatric-related hospitalizations decreased significantly after RLAT initiation, and patients had fewer inpatient hospitalizations and ER visits (all p < .0001). Conclusion The

    Background A health utility value represents an individual’s preference for living in a specific health state and is used in cost-utility analyses. This study investigates the impact of continuing medical therapy on health utility outcomes in patients with chronic rhinosinusitis (CRS). Methods The Medical Outcomes Study Short Form-6D (SF-6D) was administered to patients prospectively enrolled in a longitudinal study examining treatment outcomes for CRS. Patients were prescribed robust, initial medical therapy and then elected to continue with medical therapy (n=40) or undergo endoscopic sinus surgery (ESS), followed by medical therapy (n=152). Patients observed through treatment crossover to ESS were also evaluated (n=20). Health utility values (SF-6D) were generated at baseline, 6-months, and 12-months follow-up for both cohorts and evaluated using repeated measures ANOVA. Results Treatment crossover patients were found to have a significantly higher prevalence of previous sinus surgery compared to medical management (χ2=6.91; p=0.009) and surgical intervention (χ2=8.11; p=0.004) subgroups. Mean baseline utility value for the medical therapy cohort was significantly better compared to the ESS cohort (0.76[0.12] versus 0.70[0.15]; p=0.023). Significant improvement in health utility was reported in the ESS cohort (F(2)=37.69; p<0.001), while values remained stable, without significant improvement, in both the medical therapy cohort (F(2)=0.03; p=0.967) and treatment crossover cohort (F(2)=2.36; p=0.115). Conclusions Patients electing continued medical management report better baseline health utility compared to patients electing ESS. Patients electing ESS demonstrate significant improvement in health utility while those electing continued medical management demonstrate stable health utility over 12 months. PMID:26140502

    Objective To determine the clinical utility of bone scintigraphy in patients with limb pain of suspected musculoskeletal origin. Material and Methods All patients aged ≥18 years who were referred for diagnosis and management of limb pain were diagnosed on the basis of history, physical examination, and investigations excluding bone scintigraphy. After the presumptive diagnosis was made (the pre-test diagnosis), all subjects underwent bone scintigraphy, or if they had a previous bone scintigram for their pain condition, the results of that scintigram were reviewed. Then, the pre-test diagnosis was reviewed in light of the bone scintigraphy findings and repeat clinical assessment as needed. The post-test diagnosis was considered either as unchanged diagnosis or changed diagnosis for the region or regions of interest. Results There were 118 females (54.8%) and 97 males (45.2%). The mean age of the entire group was 36±8.1 years (range: 18–87 years). The mean duration of the symptoms was 17.4±11.2 months (range: 1–264 months). Of the 215 subjects, 212 had a bone scintigram. Of these 212 subjects, none had a changed diagnosis. Conclusion In the evaluation of limb pain of suspected musculoskeletal origin, scintigraphy is unlikely to alter the pre-test diagnosis or affect treatment decisions after history, physical examination, and non-scintigraphic investigations. The clinical utility of scinitigraphy in this setting is low. PMID:27708914

  10. Text message program improves outcomes, decreases ED utilization among ED patients with poorly controlled diabetes.

    PubMed

    2014-02-01

    Diabetic patients who lack access to primary care tend to frequent the ED, often with complications from their disease that could have been prevented with proper management and education. To get around the problem of access, researchers tested an automated program that continuously delivered educational messaging via text to a group of patients who presented to the ED with poorly controlled diabetes. After six months, researchers noted improvements in Hb A1c levels, self-reported medication adherence, and ED utilization when compared with a control group. And the impact was particularly noteworthy among Latinos, according to the researchers. The text messaging program, dubbed TExT-Med, was developed by four physicians and two diabetes educators. The messages were delivered daily, and contained educational as well motivational content derived from the National Diabetes Education Program.There were also medication reminders, healthy living challenges, and trivia questions about diabetes. At six months, Hb A1c levels decreased by 1.05% in the intervention group, compared to 0.60% in the control group, and self-reported medication adherence improved from 4.5 to 5.4 (as measured on an 8 point scale) in the intervention group versus a decrease of 0.1 in the control group. During the six-month study period, 35.9% of patients in the intervention group presented to the ED for care, as compared to 51.6% of patients in the control group.

    Purpose. To analyze the patterns and associations of adjunctive service visits by head and neck cancer patients receiving primary, concurrent chemoradiation therapy. Methods. Retrospective chart review of patients receiving adjunctive support during a uniform chemoradiation regimen for stages III-IV head and neck squamous cell carcinoma. Univariate and multivariate models for each outcome were obtained from simple and multivariate linear regression analyses. Results. Fifty-two consecutive patients were assessed. Female gender, single marital status, and nonprivate insurance were factors associated with an increased number of social work visits. In a multivariate analysis, female gender and marital status were related to increased social work services. Female gender and stage IV disease were significant for increased nursing visits. In a multivariate analysis for nursing visits, living greater than 20 miles between home and hospital was a negative predictive factor. Conclusion. Treatment of advanced stage head and neck cancer with concurrent chemoradiation warrants a multidisciplinary approach. Female gender, single marital status, and stage IV disease were correlated with increased utilization of social work and nursing services. Distance over 20 miles from the center was a negative factor. This information may help guide the treatment team to allocate resources for the comprehensive care of patients. PMID:23118755

    This paper describes the evolution of different concepts of classifying and defining Temporomandibular Disorders (TMD) for both clinical and research settings. The literature is reviewed with respect to the utility and validity of the different questionnaire and examination procedures that have been used to assess TMD patients. The presented view is that many of these procedures have not been validated, that there is a lack of standardization in the use of the procedures themselves, and that an ideal method of classifying this broad group of patients into better-defined subgroups has not yet been developed. More standardized and better-defined research by trained and calibrated researchers is needed worldwide to elucidate these subgroups so that a better and widely agreed upon research classification system can be developed for widespread use. It also seems clear that as research requirements for defining TMD patient subgroups become more stringent over time, it may not be practical for the clinician to implement them on a day-to-day basis in his or her practice. As such, a practical utilitarian definition of the common subtype of TMD patients is also needed which parallels any research grouping, so that data from research are valuable and generalizable to the practicing clinician.

    Gait analysis is a useful tool in understanding movement impairments, which impact on patient well-being. The use of gait analysis in patients with diabetes has led to improvements in health care including the treatment and prevention of ulceration and development of targeted exercise interventions. The current convention when analyzing gait is to address specific complications of diabetes, controlling for potential influencing conditions within a study sample to understand the effects of the few specific complications chosen for analysis. Databases allow for the storage of data in a structured format, allowing easy access to large quantities of data in a consistent, comparable manner. A database of gait analyses of patients with diabetes has the potential to include far greater sample sizes for statistical analyses, allowing multiple influencing factors to be assessed simultaneously, and relationships identified between multiple influencing factors. However, a database of this type would encounter ethical and methodological challenges in its implementation, which are discussed. This article introduces some of the potential benefits, challenges, and utility of a gait database for diabetes patients. We highlight that, whereas the creation of a database within this clinical population would be a complex process both ethically and practically, huge potential benefits could be gained, overcoming some of the limitations faced by traditional isolated gait analysis studies.

    Background Human genetic factors influence the outcome of pegylated interferon and ribavirin hepatitis C therapy. We explored the role of IL28B, APOH and ITPA SNPs on the outcomes of triple therapy including telaprevir or boceprevir in patients with compensated cirrhosis chronically infected with HCV-1. Patients and Methods A total of 256 HCV-1 Caucasian treatment-experienced patients with compensated cirrhosis from the ANRS CO20-CUPIC cohort were genotyped for a total of 10 candidate SNPs in IL28B (rs12979860 and rs368234815), APOH (rs8178822, rs12944940, rs10048158, rs52797880, rs1801689 and rs1801690) and ITPA (rs1127354 and rs7270101). We tested the association of IL28B and APOH SNPs with sustained virological response and of ITPA SNPs with anemia related phenotypes by means of logistic regression assuming an additive genetic model. Results None of the six APOH SNPs were associated with sustained virological response. The favorable alleles of the IL28B SNPs rs12979860 and rs368234815 were associated with sustained virological response (rs12979860: OR = 2.35[1.50–3.70], P = 2x10-4). Refined analysis showed that the effect of IL28B SNPs on sustained virological response was restricted to prior PegIFN/RBV relapse (OR = 3.80[1.82–8.92], P = 8x10-4). We also confirmed the association between ITPA low activity alleles and protection against early hemoglobin decline in triple therapy (P = 2x10-5). Conclusion Our results suggest that the screening of rs12979860 may remain interesting for decision making in prior relapse HCV-1 Caucasian patients with compensated cirrhosis eligible for a telaprevir- or boceprevir-based therapy.

    Background Trastuzumab targets the human epidermal growth factor receptor-2 (HER2). Cardiotoxicity is a potential adverse effect, manifesting as either an asymptomatic decline in left-ventricular ejection fraction or infrequently as largely reversible symptomatic heart failure (HF). Monitoring recommendations differ between product labeling and 2012 guidelines, and the clinical utility of serial cardiac monitoring in patients with metastatic breast cancer remains controversial. Objective The objectives of this study were to describe the frequency of monitoring, incidence of symptomatic or asymptomatic HF, overall effect on treatment, and cost of monitoring for cardiotoxicity. Methods We preformed an institutional review board–approved retrospective chart review of breast cancer patients receiving trastuzumab from January 1, 2009, through January 1, 2014, at an academic medical center. Results Out of 154 treatments, 72% were adjuvant, and 28% were metastatic. In the adjuvant setting, a mean of 4.5 (interquartile range [IQR] = 4–5) echocardiograms (echos) over a mean of 11.5 (IQR = 11–12) months were performed. In the metastatic setting, a mean of 3.1 (IQR = 1–5) echos over a mean of 20.2 (IQR = 9–31) months were performed. Symptomatic HF events occurred in 4 adjuvant (3.6%) and 2 metastatic patients (6.5%); 10 patients (6.5%) had a treatment interruption, with 9 (90%) tolerating restart of trastuzumab. Two patients (1.3%) changed treatment as a result of cardiotoxicity. Using population incidence of HER2-positive breast cancer, $13 million could be saved if monitoring were reduced by 1 echo per patient. Conclusions Given the low incidence of clinically significant HF and cost of monitoring, less frequent monitoring may be justified. PMID:27307412

    Biomarkers of inflammation, especially C-reactive protein (CRP), have been consistently shown to predict poor outcomes in chronic hemodialysis (CHD) patients. However, the determinants of CRP and the value of its monitoring in CHD patients have not been well defined. We conducted a retrospective cohort study to evaluate possible determinants of the inflammatory response in CHD patients with a focus on dialysis catheter utilization. Monthly CRP were measured in 128 prevalent CHD patients (mean age 56.6 years [range 19-90], 68% African Americans, 39% diabetics [DM]) over a mean follow-up of 12 months (range 2-26 months). There were a total of 2405 CRP measurements (median 5.7 mg/L; interquartile range [IQR] 2.4-16.6 mg/L). The presence of a dialysis catheter (p<0.002), cardiovascular disease (p=0.01), male gender (p=0.005), higher white blood cell count (p<0.0001), elevated phosphorus (p=0.03), and lower cholesterol (p=0.02) and albumin (p<0.0001) concentrations were independent predictors of elevated CRP in the multivariate analysis. Additionally, CRP levels were significantly associated with the presence of a catheter, when comparing the levels before and after catheter insertion (p=0.002) as well as before and after catheter removal (p=0.009). Our results indicate that the presence of a hemodialysis catheter is an independent determinant of an exaggerated inflammatory response in CHD patients representing a potentially modifiable risk factor.

    Introduction To compare health services utilization and payments for cancer patients who received an implantable intrathecal drug delivery (IDD) system, consisting of a pump and catheter, vs. conventional medical management (CMM) for the treatment of cancer‐related pain. Methods This retrospective claims‐data analysis compared health services utilization and payments in a population of patients receiving either IDD or CMM for treatment of cancer pain. Patients were propensity score‐matched 1:1 based on characteristics including, but not limited to, age, gender, cancer type, comorbid conditions, and health care utilization and payments. Results From a sample of 142 IDD patients and 3188 CMM patients who met all inclusion/exclusion criteria, 73 matched pairs were obtained. In the year following implant, IDD patients had a consistent trend of lower medical utilization, and total payments that were $3195 lower compared to CMM. Conclusions Despite the high initial cost of IDD, this analysis suggests that patients with IDD incur lower medical utilization and payments over the first year post‐implant. Further analysis comprised of a larger, longitudinal sample would contribute to health economics and outcomes research, and assist with future practice guideline development. PMID:26816205

    Executive Summary Objective The objective of this evidence-based analysis was to evaluate the clinical utility of serologic testing for celiac disease in asymptomatic individuals presenting with one of the non-gastrointestinal conditions evaluated in this report. The clinical utility was based on the effects of a gluten-free diet (GFD) on outcomes specific to each of these conditions. The prevalence of celiac disease in asymptomatic individuals and one of these non-gastrointestinal conditions was also evaluated. Clinical Need and Target Population Celiac Disease Celiac disease is an autoimmune disease characterized by a chronic inflammatory state of the proximal small bowel mucosa accompanied by structural and functional changes. Technology Under Evaluation Serologic Tests for Celiac Disease There are a number of serologic tests for celiac disease available. Serologic tests are automated with the exception of the anti-endomysial antibody test, which is more time-consuming and operator-dependent than the other tests. Research Questions What is the prevalence of asymptomatic celiac disease in patients presenting with one of the non-gastrointestinal conditions evaluated? What is the effect of the gluten-free diet on condition-specific outcomes in patients with asymptomatic celiac disease presenting with one of the non-gastrointestinal conditions evaluated? What is the clinical utility of serologic testing for celiac disease in asymptomatic patients presenting with one of the non-gastrointestinal conditions evaluated? The clinical utility was defined as the impact of the GFD on disease specific outcomes. What is the risk of all-cause mortality and lymphoma in individuals with asymptomatic celiac disease? What is the budget impact of serologic testing for celiac disease in asymptomatic subjects presenting with one of the non-gastrointestinal conditions evaluated? Research Methods Study Population The study population consisted of individuals with newly diagnosed celiac

    Purpose We sought to determine whether human epidermal growth factor receptor 2 (HER2) and vascular endothelial growth factor (VEGF) expression were independent prognostic factors for gastric cancer (GC). Patients and methods A total of 678 consecutive patients with GC undergoing curative surgery between October 2010 and December 2012 had resected tissue examined for HER2 and VEGF expression using immunohistochemistry. Immunohistochemical expression of HER2 was analyzed using the DAKO-HercepTest™ and scored according to published reports. VEGF expression was calculated by multiplying the score for the percentage of positive cells by the intensity score. We defined positive expression as a score of 1+, 2+, or 3+, and a score of 0 was defined as negative expression. We compared these results to clinicopathological characteristics, including overall survival (OS). Results Multivariate analysis revealed that HER2 expression was independently associated with shorter OS (hazard ratio [HR], 1.55; 95% confidence interval [CI], 1.10–2.18; P=0.01) and with higher tumor–nodes–metastasis stage (HR, 3.88; 95% CI, 2.67–5.64; P<0.001) in patients with GC. VEGF expression was not associated with OS (HR, 1.25; 95% CI, 0.86–1.82; P=0.24). HER2 expression was still identified as an independent prognostic factor in Stage II–III patients treated with surgery and adjuvant chemotherapy (P=0.004) but not in patients who received surgery alone (P=0.61). Among patients with Stage III GC, those without HER2 expression survived longer with adjuvant chemotherapy (median 43.9 vs 32.2 months, respectively; P=0.04), whereas those with HER2 expression did not (median 37.1 vs 33.9 months, respectively; P=0.67). Conclusion HER2 expression is independently associated with OS in GC, especially in patients who are at higher risk and receive adjuvant chemotherapy after curative resection. HER2 expression may have important clinical utility in directing adjuvant treatment for Stage III GC

    Analysis of the virologic and immunomodulatory effects of an association of efavirenz (EFV), nelfinavir (NFV), and stavudine (d4T) was performed in 18 human immunodeficiency virus (HIV)-infected and highly active antiretroviral therapy (HAART)-experienced patients who failed multiple therapeutic protocols. Patients (<500 CD4(+) cells/ micro l; >10,000 HIV copies/ml) were nonnucleoside reverse transcriptase inhibitor (NNRTI)-naive and were treated for 10 months with EFV (600 mg/day) in association with NFV (750 mg three times daily) and d4T (30 or 40 mg twice daily). Measurement of HIV peptide- and mitogen-stimulated production of interleukin-2 (IL-2), gamma interferon (IFN-gamma), IL-4, and IL-10 as well as quantitation of mRNA for the same cytokines in unstimulated peripheral blood mononuclear cells were performed at baseline and 2 weeks (t1), 2 months (t2), and 10 months (t3) into therapy. The results showed that HIV-specific (but not mitogen-stimulated) IL-2 and IFN-gamma production was augmented and IL-10 production was reduced in patients who received EFV, NFV, and d4T. Therapy was also associated with a reduction in HIV RNA in plasma and an increase in CD4(+) cell count. These changes occurred in the first year of therapy (t2 and t3) and were confirmed by quantitation of cytokine-specific mRNA. Therapy with EFV, NFV, and d4T increases HIV-specific type 1 cytokine production as well as CD4 counts and reduces plasma viremia. This therapeutic regimen may be considered for use in cases of advanced HIV infection.

    From the 1950s to the 1970s, a number of in vitro systems that measured inhibition of glucose metabolism were used to predict the responsiveness of patients' tumors to chemotherapy. In vitro-in vivo correlations were excellent, with true positive predictions ranging from 68% to 96% and true negative predictions of 95% to 100%. The radiometric system is a new in vitro technique that measures the conversion of 14C-glucose to 14CO2. The system already has been utilized to screen prospective new antineoplastic agents for cytotoxicity. The present study was undertaken to determine if the radiometric system might be used to predict correctly the responsiveness of an individual patient's tumor to single-agent or combination-agent chemotherapy. Fifty-six tumor specimens were divided and tested for drug sensitivity in the radiometric system and a conventional human tumor clonning system. Overall, there was a significant correlation between in vitro and in vivo results for the conventional cloning system (P = 0.03). However, there was no significant relationship between in vitro and in vivo results for the radiometric system. The radiometric system consistently failed to predict the tumor's clinical sensitivity to single agents. A radiometric system is not useful in predicting the responsiveness of a patient's tumor to single agent chemotherapy and is not a replacement for the more biologically attractive human tumor cloning system.

The top three commonly observed comorbidities were hypertension (70.9%), anxiety disorder (68.6%), and coronary heart disease (65.1%). Furthermore, 71.4% of patients were treated with antidepressant medications, including 60.5% of patients treated with selective serotonin reuptake inhibitors, followed by noradrenergic and specific serotonergic antidepressants (9.0%) and serotonin–norepinephrine reuptake inhibitors (8.3%). The proportions of patients who discontinued their initial antidepressant within the first and second months after the index date were 45.4% and 77.0%, respectively. Concomitant medications were prescribed for 76.8% of patients. Only 0.42% of patients experienced ≥1 MDD-related hospitalization(s) during the 1-year follow-up, and the average annual number of hospitalization was 1.2 for those hospitalized. The mean length of stay was 33.4 days per hospitalization. All patients had ≥1 MDD-related outpatient visit(s). The mean annual number of outpatient visits per patient was 3.1. The mean annual direct medical costs per patient with MDD was RMB ¥1,694.1 (48.5% for antidepressant medications), and that for hospitalized patients was RMB ¥21,291.0 (15.0% for antidepressant medications).

    Within-participant research designs are frequently used within the field of behavior analysis to document changes in behavior before, during, and after treatment. The purpose of the present article is to show the utility of within-participant research designs when working with older adults with neurocognitive disorders. The reason for advocating for these types of experimental designs is that they provide valid information about whether the changes that are observed in the dependent variable are caused by manipulations of the independent variable, or whether the change may be due to other variables. We provide examples from published papers where within-participant research design has been used with patients with neurocognitive disorders. The examples vary somewhat, demonstrating possible applications. It is our suggestion that the within-participant research design may be used more often with the targeted client group than is documented in the literature at the current date.

    To describe utilization of a biosimilar product containing filgrastim (Neutromax), data of 414 myeloma or lymphoma patients subjected to autologous SCT between 1998 and 2007 were analyzed. Filgrastim was used for mobilization of progenitors (5 days at 300 microg/day) and for the recovery of neutropenia after transplantation (100 microg/day, since day +5). In 2003, the excipient mannitol was replaced by sorbitol. A mean dose of 9.47 x 10(6)CD34(+)cells/kg was infused; 100 neutrophils/mm(3) required 5-day treatment; 500 neutrophils/mm(3), 6 days and 1000 neutrophils/mm(3), 7 days. Neutromax effect in SCT is similar to reports with other brands. No difference was found between formulations.

    Objective: to know the ethical problems experienced by oncology nurses. Method: descriptive and exploratory study with a qualitative approach, performed in inpatient units and in chemotherapy out-patients units that provide assistance to oncological patients in two capitals in the South region of Brazil. Eighteen nurses participated in this study, selected by snowball sampling type. For data collection, semi-structured interviews were carried out, which were recorded and transcribed, and then analyzed by thematic analysis. Results: two categories were established: when informing or not becomes a dilemma - showing the main difficulties related to oncological treatment information regarding health staff, health system, and infrastructure; to invest or not - dilemmas related to finitude - showing situations of dilemmas related to pain and confrontation with finitude. Conclusion: for the effective confrontation of the ethical problems experienced by oncology nurses to occur, it is important to invest in the training of these professionals, preparing them in an ethical and human way to act as lawyers of the patient with cancer, in a context of dilemmas related mainly to the possibility of finitude.

    Buprenorphine-medication assisted therapy (B-MAT) is an effective treatment for opioid dependence, but may be considered cost-prohibitive based on ingredient cost alone. The purpose of this study was to use medical and pharmacy claims data to estimate the healthcare service utilization and costs associated with B-MAT adherence among a sample of opioid dependent members. Members were placed into two adherence groups based on 1-year medication possession ratio (≥ 0.80 vs. <0.80). The B-MAT adherent group incurred significantly higher pharmacy charges (adjusted means; $6,156 vs. $3,581), but lower outpatient ($9,288 vs. $14,570), inpatient ($10,982 vs. $26,470), ER ($1,891 vs. $4,439), and total healthcare charges ($28,458 vs. $49,051; p<0.01) compared to non-adherent members. Adherence effects were confirmed in general linear models. Though B-MAT adherence requires increased pharmacy utilization, adherent individuals were shown to use fewer expensive health care services, resulting in overall reduced healthcare expenditure compared to non-adherent patients.

    Background Non-alcoholic fatty liver disease (NAFLD) is one of the most common causes of chronic liver disease associated with increased liver-related mortality. Additionally, NAFLD could potentially impair health-related quality of life. Although an approved treatment for NAFLD does not exist, a number of new drugs for treatment of NAFLD are being developed. As the efficacy and safety of these regimens are being established, their cost-effectiveness, which requires the use of quality of life metrics and health utility scores to quality-adjusted outcomes, must also be assessed. The aim of this study was to report quality of life and health utilities in patients with NAFLD with and without cirrhosis for future use. Methods Patients with NAFLD were seen in an outpatient clinic setting. Each patient had extensive clinical data and completed the Short Form-36 (SF-36 V.1) questionnaire. The SF-6D health utility scores were calculated. Results There were 89 patients with the spectrum of NAFLD completed the SF-36 questionnaire: 59 with non-cirrhotic NAFLD and 30 with cirrhosis. Patients with NAFLD had significantly lower quality of life and health utility scores than the general population (all p<0.0001). Furthermore, patients with cirrhosis had lower quality of life and utility scores than non-cirrhotic NAFLD patients: SF-6D 0.660±0.107 in non-cirrhotic NAFLD vs 0.551±0.138 in cirrhotic NAFLD (p=0.0003). Conclusions Health utilities and quality of life scores are impaired in patients with cirrhotic NAFLD. These values should be used in cost-effectiveness analysis of the upcoming treatment regimens for advanced NAFLD.

    Background Clinical guidelines recommend oral anticoagulation for stroke prevention in patients with atrial fibrillation (AF) at moderate or high risk for stroke but not at high risk for bleeding; however, studies consistently report suboptimal use of such therapy. This study used Medicare Part D claims data to assess the use of warfarin in the Medicare population. Objectives To compare real-world warfarin utilization with current treatment guideline recommendations, and to assess the effect of warfarin exposure level on patient outcomes in Medicare beneficiaries with nonvalvular AF (NVAF). Methods Patients who were recently diagnosed with NVAF were identified using a random 5% sample of Research Identifiable Files of Medicare beneficiaries in 2006 or 2007. Individuals with moderate-to-high stroke risk per CHADS2 but not at high bleeding risk per ATRIA (Anticoagulation and Risk Factors in Atrial Fibrillation) bleeding risk score were evaluated for warfarin use, as identified by the presence of ≥1 warfarin prescription claims within 12 months after the index diagnosis. Warfarin exposure level was assessed by the proportion of days covered during the 12-month follow-up period. The effect of warfarin exposure on ischemic stroke and major bleeding event rates during the 12-month follow-up period were assessed using multivariate logistic regression. Results Data from 14,149 newly diagnosed patients with NVAF (mean age, 79 years; 58.7% female) were analyzed, and of these, 7524 (53.2%) patients were identified as having moderate-to-high stroke risk and not being at high bleeding risk. Of these patients, 3110 (41.3%) did not receive warfarin within 12 months of the index diagnosis. The risk for ischemic stroke was significantly lower in those with warfarin exposure versus no warfarin exposure (adjusted odds ratio [OR], 0.51; confidence interval [CI], 0.43–0.61; P <.001) and in patients with warfarin proportion of days covered ≥80% versus those with proportion of days

    Current DSM-based instruments for personality disorders (PDs) limit the investigation of the course and outcome of treatment of these disorders. This study examined the validity of the Shedler-Westen Assessment Procedure-200 (SWAP-200) and the Structured Clinical Interview for DSM-IV Axis II PD (SCID-II) in a sample of forensic PD patients. Results based on 66 participants indicated that the SWAP-200 Q-factors reduced the frequency of diagnostic comorbidity of PD categories by half compared with the SCID-II. Only the SWAP-200's Antisocial PD category showed good convergent and discriminant validity with respect to other instruments describing aspects of PD. The validity of the cutoff score for severe antisocial PD was confirmed, and this category predicted severe incidents in the hospital at 1 year of follow-up. A violence risk scale was constructed, which differentiated violent and nonviolent offenders. The results support the validity of the SWAP-200 and its potential clinical utility with forensic PD patients.

    Characterizing the metabolic changes pertaining to hepatocellular carcinoma (HCC) in patients with liver cirrhosis is believed to contribute towards early detection, treatment, and understanding of the molecular mechanisms of HCC. In this study, we compare metabolite levels in sera of 78 HCC cases with 184 cirrhotic controls by using ultra performance liquid chromatography coupled with a hybrid quadrupole time-of-flight mass spectrometry (UPLC-QTOF MS). Following data preprocessing, the most relevant ions in distinguishing HCC cases from patients with cirrhosis are selected by parametric and non-parametric statistical methods. Putative metabolite identifications for these ions are obtained through mass-based database search. Verification of the identities of selected metabolites is conducted by comparing their MS/MS fragmentation patterns and retention time with those from authentic compounds. Quantitation of these metabolites is performed in a subset of the serum samples (10 HCC and 10 cirrhosis) using isotope dilution by selected reaction monitoring (SRM) on triple quadrupole linear ion trap (QqQLIT) and triple quadrupole (QqQ) mass spectrometers. The results of this analysis confirm that metabolites involved in sphingolipid metabolism and phospholipid catabolism such as sphingosine-1-phosphate (S-1-P) and lysophosphatidylcholine (lysoPC 17:0) are up-regulated in sera of HCC vs. those with liver cirrhosis. Down-regulated metabolites include those involved in bile acid biosynthesis (specifically cholesterol metabolism) such as glycochenodeoxycholic acid 3-sulfate (3-sulfo-GCDCA), glycocholic acid (GCA), glycodeoxycholic acid (GDCA), taurocholic acid (TCA), and taurochenodeoxycholate (TCDCA). These results provide useful insights into HCC biomarker discovery utilizing metabolomics as an efficient and cost-effective platform. Our work shows that metabolomic profiling is a promising tool to identify candidate metabolic biomarkers for early detection of HCC cases in

    Many US combat personnel have sustained nervous tissue trauma during service, which often causes Neuropathic pain as a side effect and is difficult to manage. However in select patients, synapse lesioning can provide significant pain control. Our goal is to determine the effectiveness of using Proton Beam radiotherapy for treating spinal cord injury (SCI) related neuropathic pain as an alternative to invasive surgical lesioning. The project is a joint collaboration of USC, Spinal Cord Institute VA Healthcare System, Long Beach, and Loma Linda University. This is first system of its kind that supports integration and standardization of imaging informatics data in DICOM format; clinical evaluation forms outcomes data and treatment planning data from the Treatment planning station (TPS) utilized to administer the proton therapy in DICOM-RT format. It also supports evaluation of SCI subjects for recruitment into the clinical study, which includes the development, and integration of digital forms and tools for automatic evaluation and classification of SCI pain. Last year, we presented the concept for the patient recruitment module based on the principle of Bayesian decision theory. This year we are presenting the fully developed patient recruitment module and its integration to other modules. In addition, the DICOM module for integrating DICOM and DICOM-RT-ION data is also developed and integrated. This allows researchers to upload animal/patient study data into the system. The patient recruitment module has been tested using 25 retrospective patient data and DICOM data module is tested using 5 sets of animal data.

    Attention to internal body sensations is practiced in most meditation traditions. Many traditions state that this practice results in increased awareness of internal body sensations, but scientific studies evaluating this claim are lacking. We predicted that experienced meditators would display performance superior to that of nonmeditators on heartbeat detection, a standard noninvasive measure of resting interoceptive awareness. We compared two groups of meditators (Tibetan Buddhist and Kundalini) to an age- and body mass index-matched group of nonmeditators. Contrary to our prediction, we found no evidence that meditators were superior to nonmeditators in the heartbeat detection task, across several sessions and respiratory modulation conditions. Compared to nonmeditators, however, meditators consistently rated their interoceptive performance as superior and the difficulty of the task as easier. These results provide evidence against the notion that practicing attention to internal body sensations, a core feature of meditation, enhances the ability to sense the heartbeat at rest.

  18. a Structure of Experienced Time

    2005-10-01

    The subjective experience of time will be taken as a primary motivation for an alternative, essentially discontinuous conception of time. Two types of such experience will be discussed, one based on personal episodic memory, the other on the theoretical fine texture of experienced time below the threshold of phenomenal awareness. The former case implies a discrete structure of temporal episodes on a large scale, while the latter case suggests endowing psychological time with a granular structure on a small scale, i.e. interpreting it as a semi-ordered flow of smeared (not point-like) subliminal time grains. Only on an intermediate temporal scale would the subjectively felt continuity and fluency of time emerge. Consequently, there is no locally smooth mapping of phenomenal time onto the real number continuum. Such a model has certain advantages; for instance, it avoids counterintuitive interpretations of some neuropsychological experiments (e.g. Libet's measurement) in which the temporal order of events is crucial.

    Background Anthracycline chemotherapy remains an integral part of the care for curative intent chemotherapy in breast cancer and non-Hodgkin lymphoma patients. Better tools need to be identified to predict cardiac complications of anthracycline chemotherapy. Materials and methods We investigated the utility of high-sensitivity cardiac troponin T (hscTnT), N-terminal pro-B-type natriuretic peptide, cardiac troponin T and I, and creatine kinase (CK)-MB in cancer patients receiving anthracycline-based chemotherapy, in order to determine whether baseline levels or changes in these biomarkers may help predict the onset of congestive heart failure. Results Eighteen consecutive patients with a pathologic diagnosis of breast cancer or non-Hodgkin lymphoma were enrolled. The median dose of doxorubicin exposure was 240 mg/m2 (range 240–400 mg/m2). After treatment with doxorubicin, the hscTnT increased to 19.1 pg/mL (P<0.001). CKMB and N-terminal pro-B-type natriuretic peptide levels increased to 1.1 ng/mL and 88.3 pg/mL, respectively (P=0.02). When subjects who had a decline in left ventricular ejection fraction (LVEF) by equilibrium radionuclide ventriculography were compared to those who did not have a change in LVEF, there was a suggestion that those subjects with an elevated baseline hscTnT were more likely to have a decline in LVEF (2.7 pg/mL and 0.1 pg/mL, respectively; P=0.07). Spearman correlation demonstrated that patients with higher baseline hscTnT and CKMB tended to have a greater decline in LVEF (Spearman correlation −0.54, 95% confidence interval −0.80 to −0.08 [P=0.02], and −0.49, 95% confidence interval −0.77 to −0.01 [P=0.04], respectively). Conclusion Elevations in baseline hscTnT levels are suggestive of an oncology subgroup at high risk of developing cardiac complications from their chemotherapy. Early detection by oncologists with the use of baseline biomarkers may be clinically important in designing interventions to prevent serious

    The Brunnstrom recovery stages (the BRS) consists of 2 items assessing the poststroke motor function of the upper extremities and 1 assessing the lower extremities. The 3 items together represent overall motor function. Although the BRS efficiently assesses poststroke motor functions, a lack of rigorous examination of the psychometric properties restricts its utility. We aimed to examine the unidimensionality, Rasch reliability, and responsiveness of the BRS, and transform the raw sum scores of the BRS into Rasch logit scores once the 3 items fitted the assumptions of the Rasch model.We retrieved medical records of the BRS (N = 1180) from a medical center. We used Rasch analysis to examine the unidimensionality and Rasch reliability of both upper-extremity items and the 3 overall motor items of the BRS. In addition, to compare their responsiveness for patients (n = 41) assessed with the BRS and the Stroke Rehabilitation Assessment of Movement (STREAM) on admission and at discharge, we calculated the effect size (ES) and standardized response mean (SRM).The upper-extremity items and overall motor items fitted the assumptions of the Rasch model (infit/outfit mean square = 0.57-1.40). The Rasch reliabilities of the upper-extremity items and overall motor items were high (0.91-0.92). The upper-extremity items and overall motor items had adequate responsiveness (ES = 0.35-0.41, SRM = 0.85-0.99), which was comparable to that of the STREAM (ES = 0.43-0.44, SRM = 1.00-1.13).The results of our study support the unidimensionality, Rasch reliability, and responsiveness of the BRS. Moreover, the BRS can be transformed into an interval-level measure, which would be useful to quantify the extent of poststroke motor function, the changes of motor function, and the differences of motor functions in patients with stroke.

    Introduction Rehabilitation plays an important role in the physical health of patients with hemophilia. However, comprehensive information regarding the utilization of rehabilitation for such patients remains scarce. Aim This population-based study aimed to examine the characteristics, trends, and most important factors affecting rehabilitation usage in patients with hemophilia A using a nationwide database in Taiwan. Methods Data from 777 patients with hemophilia A who were registered in the National Health Insurance Research Database between 1998 and 2008 were analyzed using SAS 9.0. Results Musculoskeletal or nervous system-related surgical procedures and clotting factor VIII concentrate costs were identified as factors affecting rehabilitation usage; musculoskeletal or nervous system-related surgical procedures (odds ratio = 3.788; P < 0.001) were the most important predictor of whether a patient with hemophilia A would use rehabilitation services. Joint disorders, arthropathies, bone and cartilage disorders, intracranial hemorrhage, and brain trauma were common diagnoses during rehabilitation use. The costs of physical therapy (physiotherapy) comprised the majority (71.2%) of rehabilitation therapy categories. Increasingly, rehabilitation therapy was performed at physician clinics. The total rehabilitation costs were <0.1% of the total annual medical costs. Conclusion Musculoskeletal or nervous system-related surgical procedures and increased use of clotting factor VIII concentrate affect the rehabilitation utilization of patients with hemophilia A the most. The findings in this study could help clinicians comprehensively understand the rehabilitation utilization of patients with hemophilia A. PMID:27690229

    Background Opioids are widely accepted as treatment for moderate to severe pain, and opioid-induced constipation is one of the most common side effects of opioids. This side effect negatively affects pain management and patients’ quality of life, which could result in increased healthcare utilization and costs. Objective To assess healthcare utilization and costs (all-cause, constipation-related, and pain-related) for individuals with and without opioid-induced constipation during the 12 months after initiation of opioid therapy for noncancer pain. Methods This retrospective cohort study was conducted using administrative claims data from HealthCore Integrated Research Environment between January 1, 2006, and June 30, 2014. The analysis was limited to patients aged ≥18 years who filled a prescription for continuous opioid treatment (≥28 days) for noncancer pain. Propensity scores were used to match opioid users with constipation (cohort 1) and opioid users without constipation (cohort 2), using a 1:1 ratio. Generalized linear models were used to estimate all-cause, constipation-related, and pain-related healthcare utilization and costs during the 12 months after the initiation of opioid therapy. Results After matching and balancing for all prespecified variables, 17,384 patients were retained in each cohort (mean age, 56 years; 63% female). Opioid users with constipation were twice as likely as those without constipation to have ≥1 inpatient hospitalizations (odds ratio, 2.28; 95% confidence interval [CI], 2.17–2.39) during the 12 months. The total mean adjusted overall costs per patient during the study period were $12,413 higher for patients with constipation versus those without it (95% CI, $11,726–$13,116). The total mean adjusted overall pain-related costs per patient were $6778 (95% CI, $6293–$7279) higher for the patients with constipation than those without. Among patients using opioids for noncancer pain, the annual mean constipation

    The objective of this study was to evaluate virological and pharmacological determinants of a 24-week virological response to unboosted atazanavir (ATV) in highly drug-experienced HIV-infected patients. Among patients enrolled in the ATV Expanded Access Program, those with HIV-RNA >1000 copies/mL, a genotype performed within three months from the baseline (BL), and who completed 24 weeks of treatment, were included. They received at least three antiretrovirals, including ATV 400 mg once daily without boosting. ATV plasma levels were evaluated after four weeks of treatment by high performance liquid chromatography (HPLC). ATV genotypic inhibitory quotient (GIQ) was calculated as the ratio between ATV Ctrough and the number of the BL ATV-related protease resistance mutations (among the following: 10I/V/F, 20R/M/I, 24I, 331/F/V, 36I/L/V, 46I/L, 48V, 54V/L, 63P, 71V/T/I, 73C/S/T/A, 82A/F/S/T, 84V, and 90M). Thirty-five subjects were included. At baseline, median (interquartile range) CD4+ T-lymphocytes, HIV-RNA, and ATV resistance mutations were 232.5 (106-303)/microL, 4.7 (4.2-5.1) log10 copies/mL, 2 (1-6), respectively. Thirteen (37.1%) subjects were off-therapy and 11 (31.4%) showed no PI mutation at baseline. Median steady-state ATV Ctrough was 230 ng/mL (87-520), for an ATV GIQ of 86.5 (25.5-165.5). Median HIV-RNA changes from baseline at weeks 4, 12 and 24 were -1.76 (from -0.44 to -2.12), -1.41 (from -0.41 to -2.81) and -1.44 (from -0.42 to -2.71) log10, respectively. The HIV-RNA changes were correlated to the number of ATV resistance mutations at each time point (P < 0.05), whereas no correlation was found between ATV Ctrough or ATV GIQ and HIV-RNA changes. In conclusion, the number of ATV resistance mutations is the only correlate to virological response through 24 weeks of treatment with unboosted atazanavir 400 mg once daily.

    2016-01-01

    Background It is necessary to predict the bleeding risk in patients undergoing functional endoscopic sinus surgery (FESS). To evaluate the adequacy of primary hemostasis, preoperative hemostatic screening tests are used. In the present study, we determined whether there is a positive correlation between prolonged closure time (CT) with collagen/epinephrine (CT-epi), prothrombin time (PT), international normalized ratio (INR), activated partial thromboplastin time (aPTT) and bleeding during FESS. Patients and methods We reviewed the medical records of 90 patients without bleeding histories who had undergone FESS from March 2013 to June 2014. More than 200 mL of blood loss was defined as moderate bleeding during surgery. With respect to bleeding during surgery, we determined the sensitivity, specificity, negative predictive value (NPV) and positive predictive value (PPV) of CT-epi, PT, INR and aPTT. Results Of the 90 patients, 17 (18.9%) patients had preoperative prolonged CT values and three (17.6%) patients had bleeding. In comparison, five (6.8%) of the 73 (81.1%) patients who had undergone FESS with preoperative normal PFA values experienced bleeding (P=0.171). On the other hand, patients with prolonged PT values (2, 2.2%), prolonged INR values (3, 3.3%) or prolonged PTT values (1, 1.1%) had no bleeding episode. Preoperative CT had low sensitivity (44.4%) and PPV (23.5%). Conclusion During preoperative period, the hemostatic screening may not be helpful to detect the bleeding tendency in adult patients undergoing FESS. Routine measurement of CT-epi, PT, INR and aPTT for preoperative screening may not be recommended for FESS patients. PMID:27799837

  6. Heart failure patients utilizing an electric home monitor: What effects does heart failure have on their quality of life?

    NASA Astrophysics Data System (ADS)

    Simuel, Gloria J.

    Heart Failure continues to be a major public health problem associated with high mortality and morbidity. Heart Failure is the leading cause of hospitalization for persons older than 65 years, has a poor prognosis and is associated with poor quality of life. More than 5.3 million American adults are living with heart failure. Despite maximum medical therapy and frequent hospitalizations to stabilize their condition, one in five heart failure patients die within the first year of diagnosis. Several disease-management programs have been proposed and tested to improve the quality of heart failure care. Studies have shown that hospital admissions and emergency room visits decrease with increased nursing interventions in the home and community setting. An alternative strategy for promoting self-management of heart failure is the use of electronic home monitoring. The purpose of this study was to examine what effects heart failure has on patient's quality of life that had been monitoring on an electronic home monitor longer than 2 months. Twenty-one questionnaires were given to patients utilizing an electronic home monitor by their home health agency nurse. Eleven patients completed the questionnaire. The findings showed that there is some deterioration in quality of life with more association with the physical aspects of life than with the emotional aspects of life, which probably was due to the small sample size. There was no significant difference in readmission rates in patients utilizing an electronic home monitor. Further research is needed with a larger population of patients with chronic heart failure and other chronic diseases which may provide more data, and address issues such as patient compliance with self-care, impact of heart failure on patient's quality of life, functional capacity, and heart failure patient's utilization of the emergency rooms and hospital. Telemonitoring holds promise for improving the self-care abilities of persons with HF.

    Abstract The Brunnstrom recovery stages (the BRS) consists of 2 items assessing the poststroke motor function of the upper extremities and 1 assessing the lower extremities. The 3 items together represent overall motor function. Although the BRS efficiently assesses poststroke motor functions, a lack of rigorous examination of the psychometric properties restricts its utility. We aimed to examine the unidimensionality, Rasch reliability, and responsiveness of the BRS, and transform the raw sum scores of the BRS into Rasch logit scores once the 3 items fitted the assumptions of the Rasch model. We retrieved medical records of the BRS (N = 1180) from a medical center. We used Rasch analysis to examine the unidimensionality and Rasch reliability of both upper-extremity items and the 3 overall motor items of the BRS. In addition, to compare their responsiveness for patients (n = 41) assessed with the BRS and the Stroke Rehabilitation Assessment of Movement (STREAM) on admission and at discharge, we calculated the effect size (ES) and standardized response mean (SRM). The upper-extremity items and overall motor items fitted the assumptions of the Rasch model (infit/outfit mean square = 0.57–1.40). The Rasch reliabilities of the upper-extremity items and overall motor items were high (0.91–0.92). The upper-extremity items and overall motor items had adequate responsiveness (ES = 0.35–0.41, SRM = 0.85–0.99), which was comparable to that of the STREAM (ES = 0.43–0.44, SRM = 1.00–1.13). The results of our study support the unidimensionality, Rasch reliability, and responsiveness of the BRS. Moreover, the BRS can be transformed into an interval-level measure, which would be useful to quantify the extent of poststroke motor function, the changes of motor function, and the differences of motor functions in patients with stroke.

    Background Secretory phospholipase A2 (sPLA2) may contribute to atherogenesis. To date, few prospective studies have examined the utility of sPLA2 for risk stratification in coronary artery disease (CAD). Methods Plasma sPLA2 activity was measured at baseline in 3708 subjects in the PEACE randomized trial of trandolapril versus placebo in stable CAD. Median follow-up was 4.8 years. Cox regression was used to adjust for demographics, clinical risk factors, apolipoprotein B, apolipoprotein A1, and medications. Results After multivariable adjustment, sPLA2 was associated with an increased risk of cardiovascular death, myocardial infarction or stroke (adjusted hazard ratio quartile 4:quartile 1 1.55, 95% CI 1.13–2.14) and cardiovascular death or heart failure (adjusted hazard ratio quartile 4:quartile 1 1.91, 95% CI 1.20–3.03). In further multivariable assessment, increased activities of sPLA2 were associated with the risk of cardiovascular death, myocardial infarction or stroke (adjusted hazard ratio 1.47, 95% CI 1.06–2.04) independent of lipoprotein-associated phospholipase A2 mass and C-reactive protein, and modestly improved the area under the curve (AUC) beyond established clinical risk factors (AUC 0.668 to 0.675, P=0.01). sPLA2, NT-pro B-type natriuretic peptide and high-sensitivity cardiac troponin T were all independently associated with cardiovascular death or heart failure and each improved risk discrimination (P=0.02, P<0.001, P<0.001, respectively). Conclusion sPLA2 activity provides independent prognostic information beyond established risk markers in patients with stable CAD. These data are encouraging for studies designed to evaluate the role of sPLA2 as a therapeutic target. PMID:21784767

    Purpose: Investigate the utility of urine cytology (UC) in patients older than 50 years with hematuria and sonographically suspected bladder lesion. Patients and Methods: Between April 2010 and June 2012, 152 patients above 50 years suffering from hematuria were included in this study. In all patients, ultrasound revealed a lesion suspected to be bladder cancer. Voided urine specimens were taken from all patients and transported to Pathology laboratory and processed within 1-3 h. All patients have undergone a cystoscopy examination and biopsy was taken from any suspicious lesion. The cytological diagnosis was reported as one of three categories, positive or negative or suspicious for malignancy. Results: One hundred thirty three (87.5%) patients in this study proved to have bladder carcinoma in histopathological examination. The sensitivity of UC was 53.4% and only five patients were suspicious. Percentage of positive cytology was highest among patients having gross hematuria (51.3%), posterior wall lesions (75%), papillonodular configuration (81.8%), invasive cancer (59.1%) and bilharzial affection (52.5%). Conclusion: Hematuria in patients older than 50 years with sonographically suspected bladder lesion mandates cystoscopy and biopsy. UC does not add more significant information in this group of patients. PMID:25125893

    Background The optimization of medication use during care transitions represents an opportunity to improve overall health-related outcomes. The utilization of clinical pharmacists during care transitions has demonstrated benefit, although the optimal method of integration during the care transition process remains unclear. Objective To evaluate the impact of pharmacist-provided telephonic medication therapy management (MTM) on care quality in a care transitions program (CTP) for high-risk older adults. Methods This prospective, randomized, controlled study was conducted from December 8, 2011, through October 25, 2012, in a primary care work group at a tertiary care academic medical center in the midwestern United States. High-risk elderly (aged ≥60 years) patients were randomized to a pharmacist-provided MTM program via telephone or to usual care within an existing outpatient CTP. The primary outcome was the quality of medication prescribing and utilization based on the Screening Tool to Alert Doctors to the Right Treatment (START) and the Screening Tool of Older Persons’ Prescriptions (STOPP) scores. The secondary outcomes were medication utilization using a modified version of the Medication Appropriateness Index, hospital resource utilization within 30 days of discharge, and drug therapy problems. Results Of 222 eligible high-risk patients, 25 were included in the study and were randomized to the pharmacist MTM intervention (N = 13) or to usual care (N = 12). No significant differences were found between the 2 groups in medications meeting the STOPP or START criteria. At 30-day follow-up, no significant differences were found between the 2 cohorts in medication utilization quality indicators or in hospital utilization. At 30-day follow-up, 3 (13.6%) patients had an emergency department visit or a hospital readmission since discharge. In all, 22 patients completed the study.

    New direct-acting antivirals (DAA) for hepatitis C virus (HCV) infection have achieved high cure rates in many patient groups previously considered difficult-to-treat, including those HIV/HCV co-infected. The high price of these medications is likely to limit access to treatment, at least in the short term. Early treatment priority is likely to be given to those with advanced disease, but a more detailed understanding of the potential benefits in treating those with mild disease is needed. We hypothesized that successful HCV treatment within a co-infected population with mild liver disease would lead to a reduction in the use and costs of healthcare services in the 5 years following treatment completion. We performed a retrospective cohort study of HIV/HCV-co-infected patients without evidence of fibrosis/cirrhosis who received a course of HCV therapy between 2004 and 2013. Detailed analysis of healthcare utilization up to 5 years following treatment for each patient using clinical and electronic records was used to estimate healthcare costs. Sixty-three patients were investigated, of whom 48 of 63 (76.2%) achieved sustained virological response 12 weeks following completion of therapy (SVR12). Individuals achieving SVR12 incurred lower health utilization costs (£5,000 per-patient) compared to (£10 775 per-patient) non-SVR patients in the 5 years after treatment. Healthcare utilization rates and costs in the immediate 5 years following treatment were significantly higher in co-infected patients with mild disease that failed to achieve SVR12. These data suggest additional value to achieving cure beyond the prevention of complications of disease.

    Background Syncope in elderly patients with heart disease is a growing problem. Its aetiological diagnosis is often difficult. We intended to investigate the value of the electrophysiological study (EPS) in old patients with syncope and heart disease. Methods EPS was performed in 182 consecutive patients with syncope and heart disease, among whom 62 patients were ≥75 years old and 120 patients <75. Results Left ventricular ejection fraction was 43.9±11.7% in patients ≥75 and 41.1±12.6% in patients <75. During EPS, induced sustained ventricular arrhythmias were as frequent in both groups (27.4% in patients ≥75 versus 27.5% in patients <75, p=0.99) whereas AV conduction abnormalities were more frequent in older patients (37.1% in patients ≥75 versus 18.3% in patients<75, p<0.005). Syncope remained unexplained in 35.5% of patients ≥75 and in 51.7% of patients <75 (p<0.04). ICD was more likely to be implanted in younger patients than in patients ≥75 years (37.5% vs 21% respectively, p<0.009). During a mean follow-up period of 3.3±3 years, the 4-year-survival rate was 66.9±6.8 % in patients ≥75 and 75.9±6.2 % in patients <75 years. The main cause of death was heart failure in both groups. The factors related to a worse outcome in a multivariate analysis were low LVEF and higher age. Conclusion Complete EPS allows the identification of treatable causes in a high proportion of elderly patients with syncope and heart disease. Yet, the prognosis of these patients is mainly related to LVEF and age. PMID:25852241

    Prescribing safe and effective medications is a challenge in psychiatry. While clinical use of pharmacogenomic testing for individual genes has provided some clinical benefit, it has largely failed to show clinical utility. However, pharmacogenomic testing that integrates relevant genetic variation from multiple loci for each medication has shown clinical validity, utility and cost savings in multiple clinical trials. While some challenges remain, the evidence for the clinical utility of "combinatorial pharmacogenomics" is mounting. Expanding education of pharmacogenomic testing is vital to implementation efforts in psychiatric treatment settings with the overall goal of improving medication selection decisions. PMID:26937360

    Sepsis is a potentially fatal response to infection affecting patients across the life span. Sepsis can progress from systemic inflammatory response to severe sepsis and septic shock if not recognized promptly and managed effectively. Risk factors for sepsis include age, gender, the presence of invasive devices (eg, urinary catheters), and chronic medical conditions (eg, chronic obstructive pulmonary disease). Sepsis awareness is essential and includes identification of population-focused risk factors, recognition of clinical signs and symptoms, and timely implementation of interventions. The purpose of this article was to examine sepsis in older adults, including prevalence, atypical presentation of the condition, and considerations for sepsis management in the elderly population.

    2013-05-01

    Through its newly created Consistent Care Program, St. Luke's Hospital in Cedar Rapids, IA, has been able to significantly reduce ED utilization among patients who have been identified as having used the ED at least 12 times in the past year. Patients who meet program criteria are automatically identified once per month. A committee of social workers, nurses, and providers then creates care plans for these individuals, so that when they present to the ED, emergency providers will have a consistent road map to follow. In one year, the program has reduced the number ED visits among frequent utilizers by one-third, saving the hospital close to $1 million. Of the original 103 patients who were first identified for the program in January of 2012, only 10 patients still meet the criteria of visiting the ED 12 times in 12 months. Administrators say that key elements of the program are case manager who can interact with the patients and their providers, a mechanism for flagging these patients when they present to the ED, and engaged providers.

    We constructed an integrated personal identification workflow chart using both bar code reading and an all in-one laboratory information system. The information system not only handles test data but also the information needed for patient guidance in the laboratory department. The reception terminals at the entrance, displays for patient guidance and patient identification tools at blood-sampling booths are all controlled by the information system. The number of patient identification errors was greatly reduced by the system. However, identification errors have not been abolished in the ultrasound department. After re-evaluation of the patient identification process in this department, we recognized that the major reason for the errors came from excessive identification workflow. Ordinarily, an ultrasound test requires patient identification 3 times, because 3 different systems are required during the entire test process, i.e. ultrasound modality system, laboratory information system and a system for producing reports. We are trying to connect the 3 different systems to develop a one-time identification workflow, but it is not a simple task and has not been completed yet. Utilization of the laboratory information system is effective, but is not yet perfect for patient identification. The most fundamental procedure for patient identification is to ask a person's name even today. Everyday checks in the ordinary workflow and everyone's participation in safety-management activity are important for the prevention of patient identification errors.

    An evolution in nursing in the United Kingdom in the 1970s from rule-bound toward holistic, autonomous practice engendered an examination of nursing's body of knowledge and how it is incorporated into practice. This article describes Barbara Carper's (1978) Fundamental Patterns of Knowing in Nursing (empiric, ethical, aesthetic, and personal knowledge), and links it to three major worldviews of the way in which knowledge is sought (positivism, naturalism, and critical social theory). Carper's model was used in the United Kingdom as the basis for a curriculum of structured reflective practice using workshops, journaling, and clinical supervision. An example from a practitioner's diary demonstrates how Carper's model informs reflection on an interaction with a patient with newly diagnosed cancer. PMID:24730190

    Background Type 2 diabetes is a common and costly illness, associated with significant morbidity and mortality. Despite this, there is relatively little information on the ‘real-world’ medication utilization patterns for patients with type 2 diabetes initiating exenatide BID or glargine. The objective of this study was to evaluate the ‘real-world’ medication utilization patterns in patients with type 2 diabetes treated with exenatide BID (exenatide) versus insulin glargine (glargine). Methods Adult patients( ≥18 years of age) with type 2 diabetes who were new initiators of exenatide or glargine from October 1, 2006 through March 31, 2008 with continuous enrollment for the 12 months pre- and 18 months post-index period were selected from the MarketScan® Commercial and Medicare Databases. To control for selection bias, propensity score matching was used to complete a 1:1 match of glargine to exenatide patients. Key study outcomes (including the likelihood of overall treatment modification, discontinuation, switching, or intensification) were analyzed using survival analysis. Results A total of 9,197 exenatide- and 4,499 glargine-treated patients were selected. Propensity score matching resulted in 3,774 matched pairs with a mean age of 57 years and a mean Deyo Charlson Comorbidity Index score of 1.6; 54% of patients were males. The 18-month treatment intensification rates were 15.9% and 26.0% (p < 0.0001) and the discontinuation rates were 38.3% and 40.0% (p = 0.14) for exenatide and glargine, respectively. Alternatively, 14.9% of exenatide-treated patients switched therapies, compared to 10.0% of glargine-treated patients (p < 0.0001). Overall, glargine-treated patients were more likely to modify their treatment [hazard ratio (HR) = 1.33, p < 0.0001] with shorter mean time on treatment until modification (123 vs. 159 days, p < 0.0001). Compared to exenatide-treated patients, glargine-treated patients were more likely to

    We surveyed 150 methadone maintenance treatment program (MMTP) patients about pain, pain treatment utilization, perceived efficacy of prior pain treatment, and interest in pursuing pain treatment at the MMTP. Respondents with chronic severe pain (CSP) (i.e., pain lasting at least 6 months with moderate to severe pain intensity or significant pain interference) and “some pain” (i.e., pain reported in the previous week but not CSP) endorsed similar rates of past-week and lifetime allopathic or standard medical (with the exception of lifetime medical use of non-opiate medication) and complementary and alternative medicine (CAM) utilization for pain reduction. Prior pain treatments were perceived to be less effective by CSP than SP patients but both groups had equivalent high rates of interest in pain treatment associated with the MMTP. These findings may have implications for resource and program planning in MMT programs. PMID:19874157

    Maxillary canines and first molars are the most common ectopic teeth in young people. Ectopic buccal eruption of maxillary canines is strongly associated with lack of space or crowding in the dental arch. This report demonstrates the management of a buccally erupted maxillary canine in an 11-year, 8-month-old boy without sufficient space. The patient had a mostly dental Class II occlusion and was in the late mixed dentition, and the root development of his canines was consistent with his dental age. To correct the distal occlusion and gain space in the maxillary arch for the eruption of both canines, the patient received cervical headgear. To guide the maxillary left canine into occlusion, it was surgically exposed and a modified utility arch inserted. The result of this approach proves that a custom-designed utility arch allows the distal movement of a buccally displaced canine, while at the same time increasing the maxillary arch length.

    Dual energy computed tomography (DECT) utilizes the material change in attenuation when imaged at two different energies to determine the composition of urinary calculi as uric acid or non-uric acid. We discuss a series of case reports illustrating DECT's ability to provide immediate determination of uric acid versus non-uric acid calculi and facilitate more informed clinical decision-making. Further, these cases demonstrate a unique population of patients with ureteral stents and percutaneous nephrostomy tubes that benefit from DECT's ability to create a virtual color contrast between an indwelling device and the stone material and thereby significantly impacting patient morbidity.

    In their search for a cure, a significant number of cancer patients use nonproven treatment (NPT) methods. However, little is known about patient and disease characteristics associated with the use of these methods. In this trial, we evaluated the prevalence of and the factors associated with the usage of nonproven cancer remedies in a teaching hospital in Turkey. A self-administered questionnaire was given to 135 cancer patients attending the outpatient clinics of a medical oncology department. Patients' demographic data, their usage of nonproven methods, and possible contributing factors were explored. Our cohort mainly comprised poor patients with only primary school education. Overall, 50% of our patients had used or were using NPT methods. Medicinal herbs (mainly stinging nettle) were the most frequently used remedy. In contrast, such "complementary therapies" as exercise, relaxation, and meditation were not employed. In multivariate analysis, only duration of disease was found to be significantly associated with NPT utilization [P=0.05, relative risk (RR)=1.94]. In addition, patient education level was marginally significant (P=0.07, RR=0.36). Apart from long duration of disease and being better educated, no other clinical, social, economic and cultural factors evaluated were associated with the use of NPT in our group of Turkish patients. Since these treatments are sometimes costly and have questionable efficacy and toxicity, proper scientific trials are needed to clarify whether such methods have a real role in cancer management.

    Recent studies have reported that the rate of growth in utilization of noninvasive diagnostic imaging has slowed, with a concomitant reduction in total payments to providers in the Medicare Part B fee-for-service population. Utilization and payment growth trends in commercially insured populations, however, are not as well understood. We used the Truven Health Analytics MarketScan® Commercial Claims and Encounters database containing more than 29 million individuals to investigate commercially insured population trends in utilization of and payments for CT, MRI, PET, and ultrasound procedures in the years 2007-2011. We found that imaging use--after a brief downturn in 2010--rose again in 2011, coupled with substantial increases in adjusted payments for all four imaging modalities, raising concerns about future efforts to stem growth in imaging use and associated spending.

    2013-01-01

    Background The purpose of this study was to describe comorbidities, healthcare costs, and resource utilization among patients with chronic non-infectious uveitis initiating corticosteroid, immunosuppressants, or biologics. In this retrospective cohort study, patients with a non-infectious uveitis diagnosis and continuous insurance coverage during a 6-month baseline were selected from a privately insured claims database with 80.7 million enrollees. Index dates were defined as the first prescription/administration of a corticosteroid, immunosuppressant, or biologic between 2003 and 2009. Comorbidities, healthcare costs, and utilization were analyzed in a per-member-per-month (PMPM) framework to account for varying between-patient treatment periods, defined as continuous medication use within the same class. Wilcoxon rank-sum and chi-square tests were used for comparisons of costs and categorical outcomes. Results Patients on corticosteroids (N = 4,568), immunosuppressants (N = 5,466), and biologics (N = 1,694) formed the study population. Baseline PMPM inpatient admission rates were 0.029 for patients on corticosteroids, 0.044 for patients on immunosuppressants, and 0.045 for patients on biologics (p < 0.001 immunosuppressants or biologics versus corticosteroids); during treatment, PMPM inpatient admissions increased to 0.044 and 0.048 for patients taking corticosteroids and immunosuppressants, respectively, but decreased to 0.024 for patients taking biologics (p < 0.001 versus corticosteroids and p = 0.003 versus immunosuppressants). Baseline average PMPM costs for patients taking corticosteroids, immunosuppressants, and biologics were US$935, US$1,738, and US$1,439 (p < 0.001 between groups), while on-treatment PMPM costs excluding drug costs increased to US$1,129 for patients taking corticosteroids but lowered to US$1,592 for patients taking immunosuppressants, and US$918 for patients taking biologics (p < 0.001 versus

    The association of anemia with chronic renal disease is well known. The striking hematologic improvement following a successful renal allotransplantation led to the present study. Using radioactive 59Fe, ferrokinetic measurements were carried out in nine uremic patients (seven with and two without anemia), four post-allotransplant cases, three patients with iron deficiency anemia and a group of five normal subjects. Erythrocyte life-span was calculated by 51Cr-labelled, autotransfused red cells in all patients who had had transplants and in three patients with renal anemia. The results showed that in patients with renal anemia the plasma radioiron clearance was slightly delayed but the 59Fe incorporation into the circulating erythrocytes was significantly decreased. Red cell life-span was moderately shortened in two out of three uremic patients investigated. The findings constitute evidence of ineffective erythropoiesis in patients with renal anemia. By comparison, the four transplant patients showed normal 59Fe plasma clearance and red cell incorporation; the 51Cr erythrocyte survival was normal in all four patients. PMID:4931770

  10. Towards Better Test Utilization – Strategies to Improve Physician Ordering and Their Impact on Patient Outcomes

    PubMed Central

    2015-01-01

    Laboratory medicine is the single highest volume medical activity in healthcare and demand for laboratory testing is increasing disproportionately to medical activity. It has been estimated that $6.8 billion of medical care in the US involves unnecessary testing and procedures that do not improve patient care and may even harm the patient. Physicians face many challenges in accurately, efficiently and safely ordering and interpreting diagnostic tests. In order to improve patient outcomes, laboratory tests must be appropriately ordered, properly conducted, reported in a timely manner, correctly interpreted and affect a decision for future diagnosis and treatment of the patient.

    Objective The aim of the study was to examine the effectiveness of an intensive inpatient three-week multimodal therapy. We focused especially on the impact on the multimodal therapy outcome of the pre-admission number of treatment types patients had received and of medical specialist groups patients had consulted. Methods 155 patients with chronic low back pain and indication for multimodal therapy were evaluated with respect to pain intensity, depression, anxiety, well-being, and pre-admission health care utilization. In our controlled clinical trial we compared N = 66 patients on the waiting list with N = 89 patients who received immediate treatment. The waiting list patients likewise attended multimodal therapy after the waiting period. Longitudinal post-treatment data for both were collected at three- and twelve-month follow-ups. The impact of pre-admission health care utilization on multimodal therapy outcome (post) was analysed by structural equation model. Results Compared to the control group, multimodal therapy patients’ pain intensity and psychological variables were significantly reduced. Longitudinal effects with respect to pre-measures were significant at three-month follow-up for pain intensity (ES = -0.48), well-being (ES = 0.78), anxiety (ES = -0.33), and depression (ES = -0.30). Effect sizes at twelve-month follow-up were small for anxiety (ES = -0.22), and moderate for general well-being (ES = 0.61). Structural equation model revealed that a higher number of pre-admission treatment types was associated with poorer post-treatment outcomes in pain intensity, well-being, and depression. Conclusion Multimodal therapy proved to be effective with regard to improvements in pain intensity, depression, anxiety, and well-being. The association between treatment effect and number of pre-admission pain treatment types suggests that patients would benefit more from attending multimodal therapy in an earlier stage of health care.

    Iron chelation therapies (ICTs) can help eliminate iron surplus in erythrocyte transfusion-dependent (TD) patients with myelofibrosis (MF). The study assessed adjusted incidence rate ratios (aIRRs) of MF-related complications and resource utilization (RU) and adjusted mean monthly inpatient cost differences in patients with TD MF treated with versus without ICT (ICT+ vs. ICT-) using data from two healthcare claims databases. Patients with ≥ 2 MF International Classification of Diseases, 9th Revision (ICD-9) diagnosis codes ≥ 30 days apart were included. Among 571 patients with TD MF, 103 (18%) were ICT+ and 468 (82%) were ICT-. ICT+ patients had lower rates of thrombocytopenia (aIRR: 0.55; p < 0.001), pancytopenia (0.53; p < 0.001), emergency room visits (0.84 [95% confidence interval: 0.74-0.96]) and inpatient stays (0.75 [0.64-0.87]), but higher rates of outpatient visits (1.21 [1.18-1.23]). Adjusted mean complication-related inpatient cost difference per month was lower in ICT+ patients (-$1804 [$570]; p = 0.004). ICT+ patients had significantly lower rates of acute care, but higher rates of outpatient care.

    The measurement of patient satisfaction is crucial to enhancing customer service and competitive advantage in the health-care industry. While there are numerous approaches to such measurement, this paper provides a case study which compares and contrasts patient and staff perceptions of customer service using both survey and focus group data. Results indicate that there is a high degree of correlation between staff and patient perceptions of customer service based on both survey and focus group data. However, the staff and patient subgroups also provided complementary information regarding patient perceptions of their service experience. Staff members tended to have more negative perceptions of service attributes than did the patients themselves. The focus group results provide complementary information to survey results in terms of greater detail and more managerially relevant information. While these results are derived from a pilot study, they suggest that diversification of data sources beyond patient surveys may enhance the utility of customer service information. If further research can affirm these findings, they create exciting possibilities for gathering valid, reliable and cost-effective customer service information. PMID:16438787

    In this study, we compared plasma levels and the diagnostic utility of hematopoietic growth factors (HGFs) with SCC-Ag in cervical cancer patients in relation to control groups and cervical intraepithelial neoplasia (CIN) patients and healthy subjects. Pretreatment plasma levels of HGFs (SCF, GM-CSF, G-CSF and M-CSF) were determined by the use of immunoenzyme assay (ELISA), and SCC-Ag by chemiluminescent microparticle immunoassay (CMIA). Significantly different concentrations of GM-CSF, G-CSF and M-CSF were observed in the group of patients with cervical cancer and CIN compared to the healthy controls. Significant differences in plasma levels of GM-CSF and M-CSF between cervical cancer and benign lesions patients were also found. The HGFs and SCC-Ag diagnostic specificities received high values. The diagnostic sensitivity and the predictive value of a positive and negative test result were higher for M-CSF than for antigen SCC in the cancer group. The M-CSF area under the ROC curve (AUC) was the largest from hematopoietic cytokines and SCC-Ag. These results suggest the potential utility of M-CSF as a good candidate for a marker of cervical cancer as well as benign lesions of this organ (CIN).

    Objectives To develop a tool which can easily access the hospital information system (HIS) to facilitate outpatient care and maximize patient satisfaction on his or her hospital visit. Methods Our Center for Informatics developed an outpatient guidance system (OGS) after careful analysis of the list of daily tasks undergone by patients and related work processes. Bluetooth beacons were installed to assist patients, to inform them of points of interest, and to guide them along the proper routes to and within the hospital. Results The OGS conveniently provided patients' clinic schedules, routes to the hospital, and direct costs; all of this information was embedded in the HIS accessed from patients' personal mobile devices or kiosks. Patients were also able to identify their locations within the hospital, receiving proper directions to subsequent task. Since its launch in October 2014, the number of mobile accesses increased from 4,011 to 8,242 per month within a year. Conclusions The substantial growth of interest in and use of our OGS in such a short period indicate that this system has been successfully incorporated into patients' daily activities. We believe that this system will continue to help improve health services and the well-being of those visiting the hospital. PMID:27525158

    The protein-sparing effects of the peripheral infusion of crystalline amino acids (PAA) was studied metabolically in selected surgical patients subjected to various degrees of stress. Twenty-one patients (sixteen cancer patients receiving chemotherapy and/or radiotherapy, three with major abdominal traumatic injuries and four with paralytic ileus) were infused with 2 1/24 hours of a solution of 4.2% Travasol amino acids with only 5% glucose as a source of nonprotein calories. One-half of the cancer patients were also allowed ad libitum oral intake of a regular hospital diet or Vivonex-HN. The nutritional status was evaluated by measuring changes in body weight, serum albumin levels and nitrogen balance. Body weight decreased in only the trauma patients. When these solutions were the sole source of nutrients all patients were in negative nitrogen balance and had significant decreases in their serum albumin levels. Serum albumin levels were preserved only when extra sources of calories were provided. The infusion of the crystalline amino acids without adequate levels of nonprotein energy did not conserve protein in these stressed patients.

    The purpose of this review was to examine the utility and accuracy of commercially available motion sensors to measure step-count and time spent upright in frail older hospitalized patients. A database search (CINAHL and PubMed, 2004-2014) and a further hand search of papers' references yielded 24 validation studies meeting the inclusion criteria. Fifteen motion sensors (eight pedometers, six accelerometers, and one sensor systems) have been tested in older adults. Only three have been tested in hospital patients, two of which detected postures and postural changes accurately, but none estimated step-count accurately. Only one motion sensor remained accurate at speeds typical of frail older hospitalized patients, but it has yet to be tested in this cohort. Time spent upright can be accurately measured in the hospital, but further validation studies are required to determine which, if any, motion sensor can accurately measure step-count. PMID:26583827

    Objective: To evaluate a trial of immunotherapy as an aid to diagnosis in suspected autoimmune epilepsy. Method: We reviewed the charts of 110 patients seen at our autoimmune neurology clinic with seizures as a chief complaint. Twenty-nine patients met the following inclusion criteria: (1) autoimmune epilepsy suspected based on the presence of ≥1 neural autoantibody (n = 23), personal or family history or physical stigmata of autoimmunity, and frequent or medically intractable seizures; and (2) initiated a 6- to 12-week trial of IV methylprednisolone (IVMP), IV immune globulin (IVIg), or both. Patients were defined as responders if there was a 50% or greater reduction in seizure frequency. Results: Eighteen patients (62%) responded, of whom 10 (34%) became seizure-free; 52% improved with the first agent. Of those receiving a second agent after not responding to the first, 43% improved. A favorable response correlated with shorter interval between symptom onset and treatment initiation (median 9.5 vs 22 months; p = 0.048). Responders included 14/16 (87.5%) patients with antibodies to plasma membrane antigens, 2/6 (33%) patients seropositive for glutamic acid decarboxylase 65 antibodies, and 2/6 (33%) patients without detectable antibodies. Of 13 responders followed for more than 6 months after initiating long-term oral immunosuppression, response was sustained in 11 (85%). Conclusions: These retrospective findings justify consideration of a trial of immunotherapy in patients with suspected autoimmune epilepsy. Classification of evidence: This study provides Class IV evidence that in patients with suspected autoimmune epilepsy, IVMP, IVIg, or both improve seizure control. PMID:24706013

    Background A frequent encounter in clinical practice is the middle-aged adult patient complaining of a toothache caused by the spread of a carious infection into the tooth's endodontic complex. Decisions about the range of treatment options (conventional crown with a post and core technique (CC), a single tooth implant (STI), a conventional dental bridge (CDB), and a partial removable denture (RPD)) have to balance the prognosis, utility and cost. Little is know about the utility patients attach to the different treatment options for an endontically abscessed mandibular molar and maxillary incisor. We measured patients' dental-health-state utilities and ranking preferences of the treatment options for these dental problems. Methods Forty school teachers ranked their preferences for conventional crown with a post and core technique, a single tooth implant, a conventional dental bridge, and a partial removable denture using a standard gamble and willingness to pay. Data previously reported on treatment prognosis and direct "out-of-pocket" costs were used in a decision-tree and economic analysis Results The Standard Gamble utilities for the restoration of a mandibular 1st molar with either the conventional crown (CC), single-tooth-implant (STI), conventional dental bridge (CDB) or removable-partial-denture (RPD) were 74.47 [± 6.91], 78.60 [± 5.19], 76.22 [± 5.78], 64.80 [± 8.1] respectively (p < 0.05). Their respective Willingness-to-Pay ($CDN) were 1,782.05 [± 361.42], 1,871.79 [± 349.44], 1,605.13 [± 348.10], 1,351.28 [± 368.62] (p < 0.05). The standard gamble utilities for the restoration of a maxillary central incisor with a CC, STI, CDB and RPD were 88.50 [± 6.12], 90.68 [± 3.41], 89.78 [± 3.81] and 91.10 [± 3.57] respectively (p > 0.05).

    Background To study the frequency and pattern of use of complementary and alternative medicine (CAM) in patients with essential hypertension attending a tertiary hypertension clinic. Methods Two hundred and twenty-five consecutive hypertensive patients attending the hypertension clinic of the Lagos University Teaching Hospital over a 3-month period were interviewed. Socio-demographic data, duration of hypertension, clinic attendance, current blood pressure, and compliance to conventional medications was documented. CAM utilization was explored using both structured and open-ended questions. Results There were 90 (40%) male and 135 (60%) female patients with mean age ± SD overall was 55.1 ± 12.4 years. 88 (39.1%) of the respondents used CAM. Herbal products were the most commonly used CAM type. Amongst the CAM users, the most common herbal product used was garlic (69.3%). Others were native herbs (25%), ginger (23.9%), bitter leaf (Vernonia amygdalina) (9.1%), and aloe vera (4.5%). 2.5% used spiritual therapy. There was no difference in the clinical characteristics, socio-economic status, and blood pressure control of CAM users and non-users. Patients who utilized CAM had higher BMI compared with those who did not, but the difference was not statistically significant (mean BMI ± SD of 29.1 ± 5.6 vs 27.1 ± 5.9 kg/m2; P = 0.05). Conclusion A significant proportion of hypertensive patients attending our tertiary facility and receiving conventional treatment also use CAM therapies. Clinicians need to be aware of this practice, understand the rationale for this health-seeking behaviour, proactively enquire about their use, and counsel patients regarding the potential of some of the therapies for adverse reactions and drug interactions.

    Utilization of services is an important indicator for estimating access to healthcare. In Norway, the General Practitioner Scheme, a patient list system, was established in 2001 to enable a stable doctor-patient relationship. Although satisfaction with the system is generally high, people often choose a more accessible but inferior solution for routine care: emergency wards. The aim of the article is to investigate contact patterns in primary health care situations for the total population in urban and remote areas of Norway and for major immigrant groups in Oslo. The primary regression model had a cross-sectional study design analyzing 2,609,107 consultations in representative municipalities across Norway, estimating the probability of choosing the emergency ward in substitution to a general practitioner. In a second regression model comprising 625,590 consultations in Oslo, we calculated this likelihood for immigrants from the 14 largest groups. We noted substantial differences in emergency ward utilization between ethnic Norwegians both in rural and remote areas and among the various immigrant groups residing in Oslo. Oslo utilization of emergency ward services for the whole population declined, and so did this use among all immigrant groups after 2009. Other municipalities, while overwhelmingly ethnically Norwegian, showed diverse patterns including an increase in some and a decrease in others, results which we were unable to explain.

    Emerging concerns regarding heart failure, arrhythmia, and sudden death in patients with muscular dystrophy are of significant clinical importance. On the other hand, little attention has been paid to renal dysfunction because these patients have low serum creatinine levels. Serum cystatin C, unaffected by muscle quantity, is a potentially superior marker for estimating renal function. Here, we present cases with muscular dystrophy in which estimated glomerular filtration rate (GFR) by cystatin C (eGFRcys) provided good agreement with simultaneously measured GFR by inulin renal clearance (differences less than 20%). Sudden death with acute heart failure occurred in a patient with underlying renal dysfunction and elevated BNP. Neurologists and cardiologists should evaluate renal function using GFR with cystatin C in patients with muscular dystrophy.

    Cutaneous melanoma is one of the highest incident-rate cancers with increasing prevalence in Western societies. Despite the advent of new approved therapeutics, the 5-year overall survival rate of stage IV melanoma patients remains below 15%. Current treatments for late stage disease have shown higher efficacy when treated at a lower disease burden. Thus, blood-based biomarkers capable of detecting melanoma prior to clinically evident distant metastasis, will improve the treatment and outcomes for melanoma patients. To that end, effective treatment of melanoma necessitates identification of patients at risk for developing distant metastases. Furthermore, employing blood biomarkers that monitor cancer progression over the course of treatment is a promising solution to post-treatment drug resistance often developed in melanoma patients. Non-invasive blood biomarker assays allow for regular dynamic monitoring of disease. "Liquid Biopsy" of blood, which exploits circulating tumor cells (CTCs), cell-free circulating tumor DNA (ctDNA) and cell-free circulating microRNA (cmiRNA), has been shown to detect prognostic factors for relapse in AJCC stage III and stage IV melanoma patients. Moreover, molecular characterization of CTC and analysis of various forms of ctDNA present promising potential in development of individualized therapy for melanoma patients. New approaches such as massive parallel sequencing (MPS) provide a comprehensive view of the disease progression, allowing for the selection of therapeutic options for individual patients. With advancements of improving molecular assays, liquid biopsy analysis as a powerful, routine clinical assay for melanoma patients, is highly promising prospective. PMID:26778792

    OBJECTIVES The objectives of this evaluation of medication use were to characterize the use of intravenous acetaminophen at our institution and to determine if acetaminophen was prescribed at age-appropriate dosages per institutional guidelines, as well as to evaluate compliance with restrictions for use. Total acquisition costs associated with intravenous acetaminophen usage is described as well. METHODS This retrospective study evaluated the use of acetaminophen in pediatric patients younger than 18 years of age, admitted to a tertiary care hospital, who received at least 1 dose of intravenous acet-aminophen between August 1, 2011, and January 31, 2012. RESULTS A total of 52 doses of intravenous acetaminophen were administered to 31 patients during the 6-month study period. Most patients were admitted to the otorhinolaryngology service (55%), and the majority of doses were administered either in the operating room (46%) or in the intensive care unit (46%). Nineteen doses (37%) of intravenous acetaminophen were administered to patients who did not meet institutional guidelines' eligibility criteria. Three patients received single doses of intravenous acetaminophen that were greater than the dose recommended for their age. One patient during the study period received more than the recommended 24-hour maximum cumulative dose for acetaminophen. Total acquisition cost of intravenous acetaminophen therapy over the 6-month study period was $530.40. CONCLUSIONS Intravenous acetaminophen was used most frequently among pediatric patients admitted to the otorhinolaryngology service during the perioperative period. Nineteen doses (37%) were administered to patients who did not meet the institutional guidelines' eligibility criteria. Our data support reinforcing the availability of institutional guidelines to promote cost-effective use of intravenous acetaminophen while minimizing the prescription of inappropriate doses.

    Fine-needle aspiration (FNA) has been increasingly utilized as a diagnostic tool in evaluating salivary gland masses, primarily to differentiate nonneoplastic from neoplastic lesions. Patients infected with human immunodeficiency virus (HIV) frequently present with salivary gland lesions. In this study, we reviewed the cytology of salivary gland lesions in HIV-infected patients and assessed the value of FNA in the diagnosis of salivary gland lesions in HIV-infected patients. One hundred and three FNAs of salivary gland lesions from 78 HIV-infected patients (63 males and 15 females) were included in our study. The patients' ages ranged from 7-65 yr, with a mean age of 40.9 yr. FNAs were classified into three categories: benign lymphoepithelial lesions (BLL) (77 cases or 74.8%), inflammatory processes (14 cases or 13.6%), including 3 reactive lymphoid hyperplasia, and neoplastic lesions (6 cases or 5.8%). The latter included three malignant lymphomas, a multiple myeloma, a metastatic adenocarcinoma from a lung primary, and a direct extension of basal-cell carcinoma. Six (5.8%) aspirates were nondiagnostic. No false-positive or false-negative cases were noted during follow-up of these patients. In conclusion, FNA is a simple and cost-effective procedure for the diagnosis of HIV-related salivary gland lesions. The majority of these lesions are cystic BLL and can be managed conservatively. Malignant lesions are rarely encountered and are readily recognized by FNA. Diagn. Cytopathol. 1999;21:260-264.

    Premature ventricular contractions (PVCs) are considered benign in patients with structurally normal hearts, particularly if they suppress with exercise. Catecholaminergic polymorphic ventricular tachycardia (CPVT) requires exercise testing to unmask the malignant phenotype. We studied risk factors and Holter monitor variables to help predict the necessity of exercise testing in patients with PVCs. We retrospectively reviewed 81 patients with PVCs that suppressed at peak exercise and structurally normal hearts referred to the exercise laboratory in 2011. We reviewed 11 patients from 2003 to 2012 whose PVCs were augmented at peak exercise (mean age 13 ± 4 years; 52 % male, 180 exercise studies). We recorded clinical risk factors and comorbidities (family history of arrhythmia or sudden unexpected death [SUD], presence of syncope) and Holter testing parameters. Family history of VT or SUD (P = 0.011) and presence of VT on Holter (P = 0.011) were significant in predicting failure of PVCs to suppress at peak heart rate on exercise testing. Syncope was not statistically significant in predicting suppression (P = 0.18); however, CPVT was diagnosed in four patients with syncope during exercise. Quantity of PVCs, Lown grade, couplets on Holter, monomorphism, and PVC elimination at peak heart rate on Holter were not predictors of PVC suppression on exercise testing. Patients with syncope during exercise, family history of arrhythmia or SUD, or a Holter monitor showing VT warrant exercise testing to assess for CPVT.

    The prognostic value of T-wave alternans (TWA) during the night time in patients with Brugada syndrome (Br-S) remains unknown. We assessed TWA for risk stratification using 24-h multichannel Holter electrocardiogram (24-M-ECG) in Br-S. We enrolled 129 patients with Br-S [grouped according to histories of ventricular fibrillation (VF), n = 16; syncope, n = 10; or no symptoms (asymptomatic), n = 103] and 11 controls. Precordial electrodes were attached to the third (3L-V1, 3L-V2) and fourth (4L-V1, 4L-V2 and 4L-V5) intercostal spaces. We measured the values of maximum TWA (max-TWA) during the night time (12 a.m.-6 a.m.) and the day time (12 p.m.-6 p.m.) and calculated parameters of heart rate variability. Compared to the asymptomatic and control groups, the VF and syncope groups showed significantly greater 3L-V2 max-TWA during the night time. The cutoff value for the 3L-V2 max-TWA during the night time was determined as 20 µV (sensitivity 94 % and specificity 48 %; p = 0.01). Multivariate analysis revealed that 3L-V2 max-TWA during the night time ≥20 µV and previous VF episodes were independent predictors of future VF episodes. During a mean follow-up period of 68 ± 37 months, 16 patients experienced VF episodes. The incidence of VF episodes was the highest during the night time (p < 0.001). The 3L-V2 max-TWA during the night time may be a useful predictor for VF episodes in patients with Br-S.

    Pharmacokinetic modeling has often been applied to evaluate vancomycin pharmacokinetics in neonates. However, clinical application of the model-based personalized vancomycin therapy is still limited. The objective of the present study was to evaluate the clinical utility and safety of a model-based patient-tailored dose of vancomycin in neonates. A model-based vancomycin dosing calculator, developed from a population pharmacokinetic study, has been integrated into the routine clinical care in 3 neonatal intensive care units (Robert Debré, Cochin Port Royal, and Clocheville hospitals) between 2012 and 2014. The target attainment rate, defined as the percentage of patients with a first therapeutic drug monitoring serum vancomycin concentration achieving the target window of 15 to 25 mg/liter, was selected as an endpoint for evaluating the clinical utility. The safety evaluation was focused on nephrotoxicity. The clinical application of the model-based patient-tailored dose of vancomycin has been demonstrated in 190 neonates. The mean (standard deviation) gestational and postnatal ages of the study population were 31.1 (4.9) weeks and 16.7 (21.7) days, respectively. The target attainment rate increased from 41% to 72% without any case of vancomycin-related nephrotoxicity. This proof-of-concept study provides evidence for integrating model-based antimicrobial therapy in neonatal routine care. PMID:26787690

    Down syndrome (DS) is the most common cause of mental retardation. The frequency of DS patients is about 1:800 and is mainly because of the presence of extra copy of chromosome number 21. Dermatoglyphic has been well established as a diagnostic aid in number of diseases having hereditary basis. Dermatoglyphic data was obtained by the use of ink and prints on a paper, from 15 cytogenetically confirmed patients of Down syndrome attending to the genetic clinic at BPKIHS. The data were correlated and compared with equal number of controls. Dermatoglyphic prints were used to evaluate the variation in the fingerprint patterns, the presence of simian crease and the difference in 'atd' 'dat' and 'adt' angles between the control and the DS patients. The results showed that both the 'atd' and 'adt' angles differed significantly from the control group. The dactylography study revealed higher incidence of loops and lower incidence of whorls in the DS patients as compared with the controls. This method is non-invasive and cost effective. The observed changes in the 'atd' and 'adt' angles plus the fingerprint patterns in the dermatoglyphic study proved that this simple technique could be a valuable tool for selecting patients of DS for cytogenetics analysis.

    This paper describes a quality improvement project designed to decrease postoperative pain, decrease post-operative nausea and vomiting (PONV), decrease time in the recovery room, and increase patient satisfaction in adult ambulatory septoplasty patients using a multimodal, preemptive analgesic regimen. The project was conducted in a community hospital setting with nine operating rooms, and a twenty one bed recovery room. Project participants included certified registered nurse anesthetists, anesthesiologists, operating room nurses, recovery room nurses, and otolaryngology surgeons. Following a period of departmental education, adult patients scheduled for outpatient septoplasty surgery received a preoperative regimen of medications that included gabapentin, celecoxib, and acetaminophen. Using a pre-post test design, (intervention group n = 17, non-intervention group n = 17) data was collected from patient and analyzed using SPSS version 18.0. The change in practice resulted in a significant decrease in pain scores in the recovery room and on discharge from the recovery room. In addition, patients who received the preemptive regimen also required significantly fewer opioid medications and were ready to be discharged from the recovery room in less time.

    Dental hygiene educators must determine which educational practices best promote critical thinking, a quality necessary to translate knowledge into sound clinical decision making. The aim of this small pilot study was to determine whether virtual patient simulation had an effect on the critical thinking of dental hygiene students. A pretest-posttest design using the Health Science Reasoning Test was used to evaluate the critical thinking skills of senior dental hygiene students at The University of Texas School of Dentistry at Houston Dental Hygiene Program before and after their experience with computer-based patient simulation cases. Additional survey questions sought to identify the students' perceptions of whether the experience had helped develop their critical thinking skills and improved their ability to provide competent patient care. A convenience sample of 31 senior dental hygiene students completed both the pretest and posttest (81.5% of total students in that class); 30 senior dental hygiene students completed the survey on perceptions of the simulation (78.9% response rate). Although the results did not show a significant increase in mean scores, the students reported feeling that the use of virtual patients was an effective teaching method to promote critical thinking, problem-solving, and confidence in the clinical realm. The results of this pilot study may have implications to support the use of virtual patient simulations in dental hygiene education. Future research could include a larger controlled study to validate findings from this study.

    Background Drug-drug interactions in patients taking warfarin may contribute to a higher risk of adverse events. Objective To identify and evaluate the prevalence and characteristics of potential DDIs with warfarin. Methods A cross-sectional study was performed in a Brazilian tertiary hospital. The electronic prescriptions of the patients receiving warfarin between January 2004 and December 2010 were analyzed. Socio-demographic, clinical, and therapeutic variables were collected. Warfarin drug-drug interactions were classified as either risk A, B, C, D, or X according to the Lexi-Interact™ Online database. Results A total of 3048 patients were identified who were prescribed warfarin. Of the 154,161 total drug prescriptions issued, 42,120 (27.3 %) were for warfarin. Evaluation of the prescriptions showed that 63.1 and 0.1 % of patients received concomitant drugs classified as having class D or X risk. It was found that 20,539 (48.7 %) prescriptions had at least one drug with a D or X risk. Patients were prescribed an average of 1.4 (±0.4) concomitant medications with a class D or X warfarin-DDI risk, the most frequent being acetylsalicylic acid and amiodarone. Conclusion The results demonstrate a high prevalence of concomitant drug prescriptions with the potential for clinically relevant DDIs with warfarin, the most frequent being acetylsalicylic acid and amiodarone.

    Amyotrophic Lateral Sclerosis(ALS) patients are unable to successfully communicate their desires, although their mentality is normal, and so, the necessity of Communication Aids(CA) for ALS patients is realized. Therefore, the authors are focused on Event-Related Potential(ERP) which is elicited primarily for the target by visual and auditory stimuli. P200, N200 and P300 are components of ERP. These are potentials that are elicited when the subject focuses attention on stimuli that appears infrequently. ALS patient participated in two experiments. In the first experiment, a target word out of five words on a computer display was specified. The five words were linked to an each electric appliance, allowing the ALS patient to switch on a target appliance by ERP. In the second experiment, a target word in a 5×5 matrix was specified by measure of ERP. The rows and columns of the matrix were reversed randomly. The word on a crossing point of rows and columns including the target word, was specified as the target word. The rate of correct judgment in the first and second experiments were 100% in N200 and 96% in P200. For practical use of this system, it is very important to determine suitable communication algorithms for each patient by performing these experiments evaluating the results.

    Diagnosis of infections in cancer patients is usually problematic since differentiating between infection and fever of unknown origin is often a considerable clinical challenge. In general, increase concentration of blood procalcitonin (PCT) is associated with severe bacterial infection. PCT with an optimal cutoff level of 0.5 ng/mL seems to be the most helpful biochemical parameter in detecting severe infections, mainly bloodstream infection, in patients with hematological cancers. In all clinical situations, the elevated level of PCT should be carefully analyzed, always with a thorough physical examination and an appropriate microbiological assessment. PMID:26858528

    Seizure localization includes neuroimaging like electroencephalogram, and magnetic resonance imaging (MRI) with limited ability to characterize the epileptogenic network. Temporal clustering analysis (TCA) characterizes epileptogenic network congruent with interictal epileptiform discharges by clustering together voxels with transient signals. We generated epileptogenic areas for 12 of 13 epilepsy patients with TCA, congruent with different areas of seizure onset. Resting functional MRI (fMRI) scans are noninvasive, and can be acquired quickly, in patients with different levels of severity and function. Analyzing resting fMRI data using TCA is quick and can complement clinical methods to characterize the epileptogenic network. PMID:27362339

    In the inherited hematologic disorder β-thalassemia major, patients receive regular, lifelong blood transfusions, which carry excess iron that the body is unable to eliminate. Chelation therapy (deferoxamine, deferiprone, deferasirox or deferoxamine-deferiprone combination) is required to reduce iron accumulation in target organs and the associated morbidity and mortality. Each chelation regimen has a distinct safety/efficacy profile and particular costs associated with its use. This review aims to provide an overview of published cost-utility analyses of currently used chelation regimens, and to comment on the potential relevance of their findings in the USA market, where deferiprone has recently been introduced.

    The objective of this study was to utilize the electronic medical record system to identify frequent lower acuity patients presenting to the Pediatric Emergency Department and to evaluate their impact on Pediatric Emergency Department overcrowding and resource utilization. The electronic medical records (EMR) of two pediatric emergency centers were reviewed from August 2002 to November 2004. Pediatric Emergency Department encounters that met any of the following criteria were classified as Visits Necessitating Pediatric Emergency Department care (VNEC): Disposition of admission, transfer or deceased; Intravenous fluids (IVF) or medications (excluding single antipyretic or antihistamine); Radiology or laboratory tests (excluding Rapid Strep); Fractures, dislocations, and febrile seizures. All other visits were classified as non-VNEC. ICD-9 (International Classification of Diseases, Ninth Revision) codes from the Pediatric Emergency Department encounters were defined as representing chronic or non-chronic conditions. Patients were then evaluated for utilization patterns, frequency of Emergency Department (ED) visits, chronic illness, and VNEC status. There were 153,390 patients identified, representing 255,496 visits (1.7 visits/patient, range 1-49). Overall, 189,998 visits (74%) required defined ED services and were categorized as VNEC, with the remaining 65,498 visits (26%) categorized as non-VNEC. With increasing visits, a steady decline in those requiring ED services was observed, with a plateau by visit six (VNEC 77% @ one visit, 64% @ six visits, p < 0.001). There were 141,765 patients seen fewer than four times, representing 92% of the patients and 74% of all visits (1.3 visits/patient, 225 visits/day). In contrast, 2664 patients disproportionately utilized the ED more than six times (maximum 49), representing 1.7% of patients and 9.8% of visits (9.4 visit/patient, 30 visits/day, p < 0.001).

Botanical herbs (including Gymnema sylvestre) and nutrients (including alpha lipoic acid and chromium) were used alongside metformin to help improve insulin sensitization; however, the greatest emphasis of treatment for this patient centered on a low-carbohydrate, whole-foods diet and regular exercise that shifted the focus to the patient's role in controlling their disease. Research on DM2 often focuses on improving drug efficacy while diet and lifestyle are generally overlooked as both a preventive and curative tool. During the 7 months of treatment, the patient's hemoglobin A1c and fasting glucose significantly decreased to within normal ranges and both cholesterol and liver enzyme markers normalized. A significant body of evidence already exists advocating for disease management using various diets, including Mediterranean, low-carb, and low-fat vegan diets; however, no clear dietary standards have been established. This study supports the use of naturopathic medicine as well as dietary and lifestyle changes to develop the most efficacious approach for the treatment of DM2. PMID:25984419

    Postprandial hypotension, defined as a fall in systolic blood pressure (SBP) of 20 mmHg or greater within 2 hours after a meal, is a risk factor for stroke, coronary events and mortality. The clinical suspicion is typically raised by episodes of postprandial syncope or falls, whereas asymptomatic postprandial hypotension is mostly neglected. The magnitude of the postprandial fall in SBP, as detected by 24-hour recording in apparently healthy middle-aged to elderly subjects, was proportional to the severity of the silent cerebrovascular damage. Postprandial hypotension can also be detected by self-measured blood pressure before and within 2 hours after meals using automatic devices. The review highlights the value of home blood pressure monitoring (HBPM) as a screening test for asymptomatic postprandial hypotension in hypertensive patients. Using a HBPM protocol that included duplicated blood pressure measurements before and after three consecutive lunches, we detected unsuspected postprandial hypotension in 27.4% of the 230 hypertensive patients screened. The prevalence of postprandial hypotension was 13.2% in controlled and 42.2% in uncontrolled hypertensive patients (p < 0.001), raising the dilemma of further lowering blood pressure in the setting of postprandial hypotension. The inclusion of preprandial and postprandial measurements in the protocol of HBPM is useful to identify hypertensive patients with postprandial hypotension and may guide adjustments in antihypertensive treatment according to postprandial blood pressure.

    The Ottawa General Hospital (OGH) is one of a growing number of institutions that has implemented a cost accounting system. The ability to track costs on a patient-specific basis provides an exciting avenue for reviewing the use of resources. With the accumulation of a complete fiscal year of data, the hospital recently embarked on a review process to identify opportunities for more detailed review with practitioners. This will support the OGH's surgical approach of targeting cuts, rather than making across-the-board reductions. The objective is to allow the hospital to maintain the highest levels of quality and service as the eroding funding situation allows. This paper describes the comprehensive approach taken by the review team to identify populations of patients that were relatively homogeneous and yet showed the greatest practice pattern variances between physicians. The method described provides a template for others to summarize large amounts of data and stratify patient groups for more detailed analysis of the patient care delivery process.

    The treatment of bleeding for haemophilic patients with inhibitors relies on the use of the bypassing agents, recombinant factor VIIa and factor eight inhibitor bypass activity (FEIBA). While both therapies are effective in the majority of bleeding episodes, there is a significant amount of interindividual variability when it comes to the response to therapy. As of yet, there is no reliable laboratory parameter that can predict the response to therapy in the same manner that factor VIII and factor IX levels predict response in non-inhibitor patients. Developing such a laboratory parameter is vital in order to maximize the clinical efficacy of these agents. Thromboelastography (TEG) is a device, which assesses clot formation over time in whole blood and has several characteristics which suggest it may be an effective way to monitor bypass agent therapy. We studied the ability of TEG to individualize the treatment regimens of three patients with high titre inhibitors assessing the response to recombinant factor VIIa, FEIBA, and when both were used sequentially. The TEG allowed for individualization of treatment for each of the three patients and resulted in more effective, convenient and less expensive treatment regimens. We thus believe that TEG is a promising device for monitoring of bypass agent therapy and should be studied further.

    Background A need exists to expand the characterization of tetrahydrobiopterin (BH4) responsiveness in patients with phenylketonuria (PKU), beyond simply evaluating change in blood phenylalanine concentrations. The clinical interpretation of BH4 responsiveness should be evaluated within the context of phenylalanine hydroxylase (PAH) genotype. Aim This investigation seeks to use a modified version of a previously developed PAH genotype severity tool, the assigned value (AV) sum, to assess the molecular basis of responsiveness in a clinical cohort and to explore the tool’s ability to differentiate BH4 responsive groups. Methods BH4 response was previously clinically classified in 58 patients with PKU, with three response groups emerging: definitive responders, provisional responders, and non-responders. Provisional responders represented a clinically ambiguous group, with an initial decrease in plasma phenylalanine concentrations, but limited ability to improve dietary phenylalanine tolerance. In this retrospective analysis, mutations in the PAH gene were identified in each patient. PAH genotype was characterized through the AV sum approach, in which each mutation is given an AV of 1, 2, 4, or 8; the sum of both mutations’ AV corresponds to genotype severity, with a lower number representing a more severe phenotype. An AV sum cutoff of 2 (indicative of the most severe genotypes) was used to dichotomize patients and predict BH4 responsiveness. Provisional responders were classified with the definitive responders then the non-responders to see with which group they best aligned. Results In 17/19 definitive responders, at least one mutation was mild or moderate in severity (AV sum>2). In contrast, 7/9 provisional responders carried two severe or null mutations (AV sum=2), suggesting little molecular basis for responsiveness. Non-responders represent a heterogeneous group with 15/25 patients carrying two severe mutations (AV sum=2), 5/25 patients carrying one

    AIM To estimate the levels of serum cytokines in chronic pancreatitis (CP) and pancreatic ductal adenocarcinoma (PDAC) patients in order to evaluate their usefulness as possible biomarkers. METHODS The study included 167 Caucasian patients: 74 with PDAC (28 men and 42 women, aged 30-88 years), 78 with CP (50 men and 21 women, aged 20-79 years) and 15 age-matched healthy controls hospitalized in the Department of Digestive Tract Diseases, Medical University of Lodz, Poland between 2006 and 2013. Serum MCP-1, transforming growth factor (TGF)-β1, HA and s-Fr were measured in patients with CP (n = 78), PDAC (n = 74) and healthy controls (n = 15) using ELISA (Corgenix United Kingdom Ltd R and D Systems). The severity of CP was assessed according to the Cambridge classification. RESULTS Both patients with CP and PDAC had a significantly higher mean TGF-β1 serum level (1066 ± 582 and 888 ± 356 vs 264 ± 93, P < 0.0001), mean s-Fr (2.42 ± 1.385 and 2.41 ± 1.275 vs 0.6 ± 0.370, P < 0.0001) and mean HA (199 ± 254 and 270 ± 358 vs 40 ± 26, P < 0.0001) compared to controls. There was no difference in mean MCP-1 between all the groups. There were no significant differences in any cytokine levels between the PC and PDAC groups. No significant differences between serum cytokines depending on age, gender or smoking status were found in CP patients. Mean s-Fr concentration was significantly higher in CP, lasting longer than 5 years compared to those with a shorter disease clinical course (2.639 ± 1.125 vs 1.870 ± 0.970, P < 0.03). There was no correlation between tumor size, localization or TNM classification and serum TGF-β1, MCP-1, s-Fr and HA levels in patients with PDAC. No significant differences between cytokines depending on diabetes presence in CP were found. Nevertheless, mean serum TGF-β1 concentration in PDAC patients was higher in those with diabetes compared to the remaining group (986 vs 839, P = 0.043). CONCLUSION Serum TGF-β1, s-Fr and HA may be

    Introduction: Chronic osteomyelitis is a disease that requires fastidious treatment to eliminate. However, when eradication is unable to be achieved through exhaustive modalities of antibiotic therapy and multiple debridements, significant resection of the infected bone and soft tissue must be considered, including amputation. Here we report of a salvage procedure for chronic osteomyelitis of the left tibia by employing a rotationplasty to avoid an above knee amputation and instead provide the patient with a below knee amputation. Case Report: A 51-year-old male presented to the emergency department after noticing dehiscence of an operative wound with exposure of an implant in the left lower extremity. Two years prior to presentation, the patient was involved in a motorcycle accident and underwent four surgeries in the Dominican Republic for an open fracture of the left tibia and fibula, including a procedure that involved the placement of an implant in the left proximal tibia. Tissue biopsies from the wound confirmed that the patient had osteomyelitis of the left proximal tibia. After extensive surgical and antibiotic intervention to eradicate the patient’s osteomyeltis, it was eventually determined that an amputation would be necessary. In order to avoid an above knee amputation, a salvage procedure was conducted by employing a rotationplasty to provide the patient with a below knee amputation. Conclusion: When amputation is deemed necessary, sparing the knee joint is associated with decreased energy expenditures, increased patient satisfaction and overall better postoperative outcomes. As part of a multi-disciplinary team, orthopaedics, plastic surgery, infectious disease, and medical services successfully treated this case of chronic osteomyelitis of the left proximal tibia by employing a rotationplasty to avoid an above knee amputation and achieve a below knee amputation.

    Dynamic analysis techniques may uncover abnormalities in heart rate (HR) behavior that are not easily detectable with conventional statistical measures. However, the applicability of these new methods for detecting possible abnormalities in HR behavior in various cardiovascular disorders is not well established. Conventional measures of HR variability were compared with short-term (< or = 11 beats, alpha1) and long-term (> 11 beats, alpha2) fractal correlation properties and with approximate entropy of RR interval data in 38 patients with stable angina pectoris without previous myocardial infarction or cardiac medication at the time of the study and 38 age-matched healthy controls. The short- and long-term fractal scaling exponents (alpha1, alpha2) were significantly higher in the coronary patients than in the healthy controls (1.34 +/- 0.15 vs 1.11 +/- 0.12 [p <0.001] and 1.10 +/- 0.08 vs 1.04 +/- 0.06 [p <0.01], respectively), and they also had lower approximate entropy (p <0.05), standard deviation of all RR intervals (p <0.01), and high-frequency spectral component of HR variability (p <0.05). The short-term fractal scaling exponent performed better than other heart rate variability parameters in differentiating patients with coronary artery disease from healthy subjects, but it was not related to the clinical or angiographic severity of coronary artery disease or any single nonspectral or spectral measure of HR variability in this retrospective study. Patients with stable angina pectoris have altered fractal properties and reduced complexity in their RR interval dynamics relative to age-matched healthy subjects. Dynamic analysis may complement traditional analyses in detecting altered HR behavior in patients with stable angina pectoris.

    A number of surgery practice models have been developed to address general and trauma surgeon workforce shortages and on-call issues and to improve surgeon satisfaction. These include the creation of acute or urgent care surgery services and "surgical hospitalist" programs. To date, no practice models corresponding to those developed for general and trauma surgeons have been proposed to address these same issues among vascular surgeons or other surgical subspecialists. In 2003, our practice established a Vascular Surgery Hospitalist program. Since its inception nearly a decade ago, it has undergone several modifications. We reviewed hospital administrative databases and surveys of faculty, residents, and patients to evaluate the program's impact. Benefits of the Vascular Surgery Hospitalist program include improved surgeon satisfaction, resource utilization, timeliness of patient care, communication among referring physicians and ancillary staff, and resident teaching/supervision. Elements of this program may be applicable to a variety of surgical subspecialty settings.

    Microarray testing has revolutionized clinical cytogenetics, as it provides a significantly higher resolution and greater clinical yield than karyotype analysis. This study assessed the clinical utility of single-nucleotide polymorphism microarray in patients with epilepsy. Study subjects were patients between the ages of birth to 23 years who were diagnosed with epilepsy and had a microarray performed at Cincinnati Children's Hospital Medical Center. Statistical analysis explored the association of microarray results and brain magnetic resonance imaging (MRI), seizure type, and structural malformations. Approximately 17.7% (26/147) of participants had an abnormal microarray as defined by laboratory guidelines. There were no differences in frequency of abnormal brain MRI or seizure type between the abnormal and normal microarray groups. There was a higher prevalence of musculoskeletal malformations (P < .0035) and cardiovascular malformations (P < .0081) in subjects with abnormal microarrays. Clinicians should consider microarray analysis in individuals who have epilepsy, especially in combination with musculoskeletal malformation or cardiovascular malformation.

    Background The precise aetiology of chronic bloating remains poorly understood and underlying gastroparesis, small bowel bacterial overgrowth and colonic inertia may, individually or collectively, play a role. Aims In this retrospective cohort analysis of symptomatic patients with chronic persistent bloating, we determined the clinical utility of wireless motility capsule and lactulose breath test in further defining the underlying aetiology for functional bloating. Methods Consecutive patients with chronic bloating underwent clinical assessment, wireless motility capsule testing and lactulose breath testing using standard protocols. Results 52 patients qualified for inclusion in this analysis, fulfilling Rome III criteria for functional bloating. Most patients (54%) had an abnormal wireless motility capsule study; of those, 11.5% had evidence of gastroparesis, 7.7% had small bowel transit delay, 15.8% had colonic inertia, 3.8% had delayed gastric and small bowel transit, 5.6% had combined gastric and colonic transit delay, 3.8% had delayed small bowel and colonic transit, and 5.6% had delayed gastric, small bowel and colon transit times. Using clinical questionnaires the median scores for bloating, constipation and eructation were not significantly different. Neither constipation nor eructation was specific to gastroparesis or colonic inertia but bloating was numerically more prevalent and severe in patients with delayed small bowel transit. 40% of patients had positive lactulose breath test but had no distinguishing clinical characteristics. Conclusions Chronic functional bloating may reflect underlying gastroparesis, small intestinal bacterial overgrowth or colonic inertia. Wireless motility capsule and lactulose breath test are useful in the assessment of patients with bloating and should be considered during evaluation. PMID:27648298

    Coarctation of the aorta (COA) is one of the more common congenital anomalies, occurring in four in ten thousand live births and accounting for five to eight percent of all congenital heart defects. COA lesions can be challenging to treat percutaneously, especially if complex vascular anatomy is a barrier to crossing the lesion. We present two cases of COA that utilized a trans-septal approach to cross the lesion in anterograde fashion, subsequently facilitating retrograde stenting of the lesions after snaring and externalizing the wire. In both cases, the trans-septal approach was employed because traditional femoral and radial approaches failed due to complex anatomy, and the trans-septal approach allowed for effective intervention without the need for surgery.

    Introduction The increasing rate of patient exposure to radiation from computerized tomography (CT) raises questions about appropriateness of utilization. There is no current standard to employ informed consent for CT (ICCT). Our study assessed the relationship between informed consent and CT utilization in emergency department (ED) patients. Methods An observational multiphase before-after cohort study was completed from 4/2010–5/2011. We assessed CT utilization before and after (Time I/Time II) the implementation of an informed consent protocol. Adult patients were included if they presented with symptoms of abdominal/pelvic pathology or completed ED CT. We excluded patients with pregnancy, trauma, or altered mental status. Data on history, exam, diagnostics, and disposition were collected via standard abstraction tool. We generated a multivariate logistic model via stepwise regression, to assess CT utilization across risk groups. Logistic models, stratified by risk, were generated to include study phase and a propensity score that controlled for potential confounders of CT utilization. Results 7,684 patients met inclusion criteria. In PHASE 2, there was a 24% (95% CI [10–36%]) reduction in CT utilization in the low-risk patient group (p<0.002). ICCT did not affect CT utilization in the high-risk group (p=0.16). In low-risk patients, the propensity score was significant (p<0.001). There were no adverse events reported during the study period. Conclusion The implementation of ICCT was associated with reduced CT utilization in low-risk ED patients. ICCT has the potential to increase informed, shared decision making with patients, as well as to reduce the risks and cost associated with CT. PMID:26759646

    Background Improper correction of hyponatremia can cause severe complications, including osmotic demyelination syndrome (ODS). The Adrogué–Madias equation (AM), the Barsoum–Levine (BL) equation, the Electrolyte Free Water Clearance (EFWC) equation and the Nguyen–Kurtz (NK) equation are four derived equations based on the empirically derived Edelman equation for predicting sodium at a later time (Na2) from a known starting sodium (Na1), fluid/electrolyte composition and input and output volumes. Methods Our retrospective study included 43 data points from 31 mostly hyponatremic patients. We calculated Na2 based on five sets of rules that were progressively more precisely calculated. Sets A–D included all 31 patients and 43 data points and set E was based on 15 patients and 27 data points. Results The root mean square error was calculated and found to be between 4.79 and 6.37 mmol/L (mEq/L) for all sets. Bland–Altman analysis showed high variability and discrepancies between the predicted and actual Na2. Conclusions Like similar studies in hypernatremic patients, the data suggest that hyponatremic modeling equations are not reliably accurate in predicting Na2 from Na1 and available clinical data regarding sodium, potassium and fluid balance over longer time frames (12–30 h). Our study was retrospective and was done in an inpatient setting and thus was subject to limitations and laboratory measurement variability, but showed that all four equations are not able to reliably predict Na2 from Na1 and inputs across a 12–30 h period.

    Background The revascularization strategy of the left main disease is determinant for clinical outcomes. Objective We sought to 1) validate and compare the performance of the SYNTAX Score 1 and 2 for predicting major cardiovascular events at 4 years in patients who underwent unprotected left main angioplasty and 2) evaluate the long-term outcome according to the SYNTAX score 2-recommended revascularization strategy. Methods We retrospectively studied 132 patients from a single-centre registry who underwent unprotected left main angioplasty between March 1999 and December 2010. Discrimination and calibration of both models were assessed by ROC curve analysis, calibration curves and the Hosmer-Lemeshow test. Results Total event rate was 26.5% at 4 years.The AUC for the SYNTAX Score 1 and SYNTAX Score 2 for percutaneous coronary intervention, was 0.61 (95% CI: 0.49-0.73) and 0.67 (95% CI: 0.57-0.78), respectively. Despite a good overall adjustment for both models, the SYNTAX Score 2 tended to underpredict risk. In the 47 patients (36%) who should have undergone surgery according to the SYNTAX Score 2, event rate was numerically higher (30% vs. 25%; p=0.54), and for those with a higher difference between the two SYNTAX Score 2 scores (Percutaneous coronary intervention vs. Coronary artery by-pass graft risk estimation greater than 5.7%), event rate was almost double (40% vs. 22%; p=0.2). Conclusion The SYNTAX Score 2 may allow a better and individualized risk stratification of patients who need revascularization of an unprotected left main coronary artery. Prospective studies are needed for further validation. PMID:27007223

    Background and Aims. Upper endoscopy is a valuable tool in the workup of gastrointestinal (GI) complaints. The purpose of this study is to determine cost and yield of taking biopsies in a normal upper GI tract. Methods. This is a retrospective study where all upper GI biopsies were identified between May 2012 and April 2013, at a tertiary care center. Clinical, procedural, and pathology reports were reviewed to identify patient demographics, procedure information, and pathology diagnosis. Results. Biopsies of the upper GI tract were taken in 1297 patients with normal upper endoscopies. In patients with normal upper endoscopy, 22% of esophageal, 44% of gastric, and 12% of duodenal biopsies were abnormal. The most frequent abnormality was reflux esophagitis in 16% of esophageal biopsies, chronic gastritis in 23% of gastric biopsies, and increased intraepithelial lymphocytes in 6% of duodenal biopsies. The additional cost for taking biopsies in a normal upper GI tract for a diagnosis of eosinophilic esophagitis was $2963 Canadian (CAD), H. pylori associated gastritis was $1404 CAD, and celiac disease was $3024 CAD. Conclusions. The yield of biopsy in normal upper endoscopy varied with location, but the additional expense can be costly and should be tailored to appropriate clinical situations. PMID:27478819

    It is uncertain whether exercise-induced zero toe brachial index sign (e-ZETS) is beneficial to prevent advanced perfusion disturbance in maintenance hemodialysis (HD) patients. In HD patients, we compared the clinical findings and prognoses among 22 toes in a resting zero toe brachial index sign (r-ZETS) group, 22 toes in an e-ZETS group, and 63 toes in a non-e-ZETS group. The hemodynamics of the lower extremities in the e-ZETS group is intermediate between the r-ZETS and non-e-ZETS groups. As the result of a 36-month follow- up observation, the r-ZETS avoidance rate was significantly lower in the e-ZETS group (63.6%; P <0.001) than the non-e-ZETS group (98.4%), showing that it was difficult to avoid advanced perfusion disturbance. The e-ZETS in HD patients may appear before r-ZETS, being beneficial as a predictor for advanced perfusion disturbance. (This is a translation of J Jpn Coll Angiol 2015; 55: 125–129.)

    Drug-eluting stents represent a breakthrough technology designed to deliver high concentrations of a bioactive agent locally to an atherosclerotic lesion, thereby minimizing systemic side effects of the drug. The safety and efficacy of drug-eluting stents have clearly been demonstrated in noncomplex lesions. This article presents an evidence-based analysis of the current experience with CYPHER sirolimus-eluting stents (Cordis Corp., Miami Lakes, FL) and TAXUS paclitaxel-eluting stents (Boston Scientific, Natick, MA) in a broad spectrum of high-risk and/or complex subsets of patients and lesions, including those with diabetes mellitus, multivessel disease, diffuse disease, very small vessels, lesions in saphenous vein grafts, chronic total occlusions, in-stent restenosis, ostial and bifurcation lesions, unprotected left main disease, and acute myocardial infarction. Emerging data in several of these subsets suggest that drug-eluting stents are safe and effective, and their use may currently be recommended, whereas in other groups of patients and lesions the efficacy and/or safety of drug-eluting stents remains to be determined, thus warranting caution. It is anticipated that penetration of drug-eluting stents will continue to increase, and fewer patients will require surgical revascularization to achieve sustained event-free survival.

    2016-01-01

    Primary biliary cholangitis (PBC), previously known as primary biliary “cirrhosis”, is a rare autoimmune liver disease characterized by the hallmark autoantibodies to mitochondrial antigens and immune-mediated destruction of small bile duct epithelial cells leading to cholestasis and cirrhosis. Surprisingly, while immune modulators have not been effective in the treatment of PBC, supplementation with the hydrophilic bile acid (BA) ursodeoxycholic acid (UDCA) has been demonstrated to slow the disease progression. However, a significant minority of PBC patients do not have a complete response to UDCA and remain at risk of continued disease progression. Although the mechanisms of action are not well understood, UDCA provided proof of concept for BA therapy in PBC. Obeticholic acid (OCA), a novel derivative of the human BA chenodeoxycholic acid, is a potent agonist of the nuclear hormone receptor farnesoid X receptor, which regulates BA synthesis and transport. A series of clinical trials of OCA in PBC, primarily in combination with UDCA, have established that OCA leads to significant reductions in serum alkaline phosphatase that are predicted to lead to improved clinical outcomes, while dose-dependent pruritus has been the most common adverse effect.

    Abstract The prognosis of breast cancer occurs in young women is usually poor. Red cell distribution width (RDW), 1 of many routinely examined parameters, has recently been proposed as a prognostic marker in solid tumors. The aim of our study was to assess the predictive value of RDW for survival in young women with breast cancer. We reviewed 203 consecutive young female patients (under 40) with invasive breast cancer diagnosed at the First Affiliated Hospital of Wenzhou Medical University between January 2008 and December 2012. Preoperational RDW, clinicopathological information, and prognostic data were collected. RDW levels were divided into 2 groups: 161 patients with low RDW (≤13.75%) and 42 patients with high RDW (>13.75%). Clinicopathological differences between the 2 groups were calculated by chi-squared test and Wilcoxon rank-sum test. Kaplan–Meier survival analysis and Cox proportional hazard regression analyses were used to examine the effect of RDW on survival. We found that high RDW was significantly associated with larger tumor size (P = 0.002), positive lymph node metastases (P = 0.011), and advanced stages (P = 0.004). Patients with high RDW showed significantly lower disease-free survival (DFS; P < 0.001) and lower overall survival (OS) rate (P < 0.001) than patients with low RDW. Moreover, the Cox regression multivariate analysis revealed that high pretreatment DRW was independently correlated with poor DFS and OS, with hazard ratio 4.819 (95% confidence interval [CI] 2.291–10.138, P < 0.001) and 5.887 (95% CI 1.666–20.802, P = 0.006), respectively. In conclusion, our study demonstrated that pretreatment RDW may be associated with DFS and OS in young women with breast cancer. Further validation and feasibility studies are required before the result of our study can be considered for clinical practice. PMID:27124030

    Background Dermatomyositis and polymyositis (DM/PM) are inflammatory myopathies characterized by muscle inflammation/weakness. Patients with DM/PM have a reduced quality-of-life and are at an increased risk for several comorbidities. Studies have assessed the incidence and prevalence of DM/PM; however, no study has estimated the burden of the diseases in terms of both healthcare resource utilization (HCRU) and work loss incurred by patients. Objective To provide a comprehensive, current estimate of the annual HCRU and work loss in DM/PM patients in the US. Methods All patients (aged 18-64 years) with a first diagnosis of DM/PM between January 1, 1998 and March 31, 2014 ('index date') were selected from a de-identified privately-insured administrative claims database. DM/PM patients were required to have continuous health-plan enrollment 12 months prior to and following their index date. Propensity-score (1:1) matching of DM/PM patients with non-DM/PM controls was carried out based on a logistic regression of demographic characteristics, comorbidities, costs, and HCRU to control for these confounding factors. Burden of HCRU and work loss (disability days and medically-related absenteeism) were compared between the matched DM/PM and the non-DM/PM cohorts over the 12-month period after the index date ('outcome period'). Results Of the 2617 DM/PM patients that met sample selection criteria, 2587 (98.9%) were matched with a non-DM/PM control. During the outcome period, DM/PM patients had significantly increased HCRU across places of service, including 44% more inpatient admissions (3.6 vs 2.5, p < 0.001), increased visits with specialists such as rheumatologists, neurologists and physical therapists, and filled 4.7 more prescriptions (32.2 vs 27.5, p < 0.001) than matched control patients. The increased HCRU led to significantly more medically-related work loss among DM/PM patients than matched controls (p < 0.001). Conclusions DM/PM imposes a substantial

    A collaborative care model (CCM) has been implemented for management of depression. This paper studies the impact that the CCM had on cost measures for the period of six months after initial diagnosis of depression compared to patients receiving usual care (UC). There was a significant increase in the CPT costs for the six months following diagnosis in the CCM group ($451.35 vs. $323.50, P < 0.001). The average CPT cost rank and CPT cost differential were also significantly increased in the CCM group. The adjusted means of the CPT costs were (when controlling for prior utilization) $452.11 for the CCM group and $322.09 for UC (P < 0.001). In the CCM group; there were 161 patients (73.5%) that achieved a clinical response for their depression compared to the UC group, which had a 15.1% (18/119) response rate (P < 0.001). There also was a significant difference between the groups in those who were symptoms free of their depression (PHQ-9 score < 5), with the CCM having 59.4% of the patients symptom-free compared to 10.9% of the UC group (P < 0.001). In this group of patients, CCM is associated with markedly improved clinical outcomes for depression, however with a modest short-term increase in CPT costs. PMID:23804062

    Background. Skin cancer is the most commonly diagnosed form of cancer in the United States (US). However, knowledge, behaviors, and attitudes regarding sun protection vary among the general population. The purpose of this study is to examine sun protection behaviors of low-income primary care patients and assess the association between these health behaviors and the self-efficacy, susceptibility, and skin cancer awareness. Methods. Uninsured primary care patients utilizing a free clinic (N = 551) completed a self-administered survey in May and June 2015. Results. Using sunscreen was the least common tactic among the participants of this study. Skin cancer awareness and self-efficacy are important to improve sun protection behaviors. Spanish speakers may have lower levels of skin care awareness compared to US born and non-US born English speakers. Male and female participants use different sun protection methods. Conclusion. It is important to increase skin cancer awareness with self-efficacy interventions as well as education on low-cost sun protection methods. Spanish speaking patients would be a target population for promoting awareness. Male and female patients would need separate gender-specific sun protection education. Future studies should implement educational programs and assess the effectiveness of the programs to further promote skin cancer prevention among underserved populations. PMID:26425119

    The value of blind terminal subcultures (7 and 30 days) and prolonged incubation (30 days) of blood cultures from immunosuppressed patients was analyzed in the Fundación Favaloro, the Fundación para la Lucha contra las Enfermedades Neurológicas de la Infancia and the Hospital de Niños Ricardo Gutiérrez. A total of 2707 blood cultures and 369 patients were included (transplantation of solid organs 154, oncohematologic disorders 106 and solid tumors 109). Bact-Alert bottles were incubated at 35 degrees C for 30 days in the Bact-Alert System. Bottles with positive signals were routinely removed, and aliquots of the broth were Gram stained and subcultured aerobically in chocolate agar and Sabouraud agar. A total of 136 bacteremic episodes were obtained. The positivization time of blood cultures was 81.6% at 24 h, 93.3% at 48 h, 94.5% at 72 h and 97.7% within 7 days. Only 3 (2.2%) episodes were positive by blind terminal subcultures and 1 (0.75%) by prolonged incubation (14 days). The median time and range of positivization in hours were 13.8 and 2.2-168, respectively. The microorganisms isolated were coagulase negative staphylococci (n = 24), Klebsiella pneumoniae (n = 22), Staphylococcus aureus (n = 21), Escherichia coli (n = 18), Acinetobacter spp (n = 9), Candida spp (n = 8), Pseudomonas aeruginosa (n = 6), Enterobacter cloacae (n = 5), Stenotrophomonas maltophilia (n = 5), Enterococcus faecalis, Salmonella spp and Capnocytophaga sputigena (n = 2), Enterobacter aerogenes, Enterococcus faecium, Citrobacter diversus, Candida albicans, Klebsiella oxytoca, Chryseomonas luteola, Serratia marcescens, Abiotrophia spp, Campylobacter jejuni, Moraxella catarrhalis, Moraxella urethralis, Neisseria sicca, beta hemolytic group G streptococci, Rhodococcus equi, Micrococcus spp, Cryptococcus neoformans and Streptococcus mitis (n = 1).

    Most cancer patients experience nausea and vomiting after surgery. Today, many methods of treatment have been developed and used for the control of such symptoms. The most important are drug therapy, relaxation, oxygen therapy and gas therapy. In addition, dexamethasone, massage therapy and using a Venturi mask have also proven effective. Due to the nature of gas consumption which leads to nausea it is recommended that use of N2O in the operating room be avoided or applied in combination with oxygen or other gases with fewer complications.

    OBJECTIVE: To determine the proportion of patients with noncardiac chest pain (NCCP) who see a gastroenterologist, the type and frequency of gastrointestinal (GI) and cardiac tests performed, and the frequency of cardiac death. PATIENTS AND METHODS: A cohort of Olmsted County, Minnesota, residents presenting to the emergency department (ED) with chest pain between January 1, 1985, and December 31, 1992, was identified through the Rochester Epidemiology Project. We assessed the frequency of ED, cardiology, and gastroenterology visits and corresponding tests after a diagnosis of NCCP (n=320). We also assessed the frequency of cardiac events. RESULTS: During follow-up, 49% of patients sought care in the ED, 42% had repeated cardiology evaluations, and 15% were seen by a gastroenterologist. Thirty-eight percent underwent esophagogastroduodenoscopy, but very few underwent manometry or a pH probe. Patients with NCCP of unknown origin had 3 times the rate of GI consultations as their counterparts with a GI disorder. Survival free of cardiac death in the subset with NCCP with a GI disorder was 90.2% at 10 years and 84.8% at 20 years, compared with 93.7% at 10 years and 88.1% at 20 years for the subset with NCCP of unknown origin. CONCLUSION: The frequency of health care utilization in NCCP patients is high, but relatively few GI consultations and even fewer GI tests are performed. Patients dismissed from the hospital with NCCP continue to experience cardiac events, which may highlight a need for more aggressive cardiovascular risk factor management in this population.

    Since 1988, IUD use by patients at Planned Parenthood of America clinics has remained constant at 0.7% of the approximately 1.8 million patients receiving contraception each year. In the past 7 years, only 18 perforations, 60 infections, and 27 difficult removals have been reported from these clinics. Moreover, there has been no evidence that the IUD poses health risks to acceptors or a major expense to the provider's malpractice insurance company. In large part, Planned Parenthood's excellent safety record associated with IUD use reflects implementation of a uniform set of IUD guidelines. These guidelines permit Planned Parenthood clinicians to provide prophylactic antibiotics in cases where an acceptor considered at low current risk of sexually transmitted diseases has a past history of pelvic inflammatory disease, gonorrhea, chlamydia infection, or mucopurulent cervicitis. Implementation of these guidelines is augmented by careful physical examination and explanation of the risks and benefits of IUD use. Planned Parenthood also distributes forms outlining the risk associated with pregnancy with an IUD in place. Finally, Planned Parenthood, unlike most other clinics, makes IUDs available to nulliparous women who clearly understand the risks.

    This retrospective cohort study describes the patterns of antibiotic use for the treatment of ventilator-associated pneumonia (VAP) in the Calgary Zone of Alberta Health Services. Timing, appropriateness, and duration of antibiotics were evaluated in two hundred consecutive cases of VAP derived from 4 adult intensive care units (ICU). Antibiotic therapy was initiated in less than 24 hours from VAP diagnosis in 83% of cases. Although most patients (89%) received empiric therapy that demonstrated in vitro sensitivity to the identified pathogens, only 24% of cases were congruent with the 2008 Association of Medical Microbiology and Infectious Disease (AMMI) guidelines. Both ICU (p = 0.001) and hospital (p = 0.015) mortality were significantly lower and there was a trend for shorter ICU length of stay (p = 0.051) in patients who received appropriate versus inappropriate initial antibiotics. There were no outcome differences related to compliance with AMMI guidelines. This exploratory study provides insight into the use of antimicrobials for the treatment of VAP in a large Canadian health region. The discordance between the assessments of appropriateness of empiric therapy based on recovered pathogens versus AMMI guidelines is notable, emphasizing the importance of using as much as possible local microbiologic and antimicrobial resistance data.

    Stroke is one of the leading causes for long-term disability in the United States. Robot-aided rehabilitation has facilitated the functional recovery of chronic stroke victims. In this study, two models were developed to aid the design of a rehabilitation robot driven by pneumatic muscle (PM) actuators, which will be applied in the treatment of the upper-limb sensorimotor deficits of stroke patients. A biomechanical model of the musculoskeletal system with exoskeleton robot powered by PM was implemented to examine the initial parameters of PM based on the kinematics and dynamics of PM assisted arm-reaching and self-feeding tasks. The outputs of the model provided guidelines for the optimal design of robot's structure. Additionally, the model can determine the necessary auxiliary force and the activation timing pattern of each PM during multi-joint coordinated movement for the robot's dynamic control. Inverse-dynamics biomechanical model generates the joint torques required to perform the movement. In addition to the musculoskeletal model, we propose a simple method to estimate the self-generated net muscle torques, therefore, to provide quantitative assessment of motor improvement of stroke patients during the therapy.

    There are gaps between recommendations on regular screening for diabetic kidney disease (DKD) and clinical practice especially in busy and low resource settings. SUDOSCAN (Impeto Medical, Paris, France) is a non-invasive technology for assessing sudomotor function using reverse iontophoresis and chronoamperometry which detects abnormal sweat gland function. Vasculopathy and neuropathy share common risk factors and we hypothesized that SUDOSCAN may be used to detect chronic kidney disease (CKD). Between 2012 and 2013, SUDOSCAN was performed in a consecutive cohort of 2833 Hong Kong Chinese adults with type 2 diabetes. Chronic kidney disease was defined as estimated glomerular filtration rate <60 ml/min/1.73m2. In this cross-sectional cohort (mean age 58.6±9.5 years, 55.7% male, median disease duration 8 [interquartile range 3–14] years), 5.8% had CKD. At a cut-off SUDOSCAN-DKD score of 53, the test had sensitivity of 76.7%, specificity of 63.4% and positive likelihood ratio of 2.1 to detect CKD. The area under receiver operating characteristic curve for CKD was 0.75 (95% confidence interval 0.72–0.79). Patients without CKD but low score had worse risk factors and complications than those with high score. We conclude that SUDOSCAN may be used to detect patients at risk of impaired renal function as part of a screening program in Chinese population, especially in outreach or low resource settings.

    Tumor glucose use in patients with non-islet-cell tumors has been difficult to measure, particularly in hepatoma, because of hepatic involvement by neoplasm. We studied a patient with nonhepatic recurrence of hepatoma after successful liver transplantation. Tumor tissue contained messenger RNA for insulin-like growth factor-II (IGF-II), and circulating high molecular weight components and E-peptide of IGF-II were increased. Glucose use measured by isotope dilution with [3-3H]glucose was 7.94 mg/kg fat-free mass per min, and splanchnic glucose production was 0.93 mg/kg fat-free mass per min. Glucose uptake and glucose model parameters were independently measured in tissues by positron emission tomography with 18F-fluoro-2-deoxy-D-glucose. Glucose uptake by heart muscle, liver, skeletal muscle, and neoplasm accounted for 0.8, 14, 44, and 15% of total glucose use, respectively. Model parameters in liver and neoplasm were not significantly different, and glucose transport and phosphorylation were twofold and fourfold greater than in muscle. This suggests that circulating IGF-II-like proteins are partial insulin agonists, and that hypoglycemia in hepatoma with IGF-II production is predominantly due to glucose uptake by skeletal muscle and suppression of glucose production.

    Background: The outreach of YouTube may have a dramatic role in the widespread dissemination of knowledge on implantable cardioverter devices (ICD). Aims: This study was designed to review and analyze the information available on YouTube pertaining to implantable cardiac devices such as implantable cardioverter defibrillators (ICDs) and pacemakers. Materials and Methods: YouTube was queried for the terms “ICD”, “Implantable Cardioverter Defibrillator”, and “Pacemaker”. The videos were reviewed and categorized as according to content; number of views and “likes” or “dislikes” was recorded by two separate observers. Results: Of the 55 videos reviewed, 18 of the videos were categorized as patient education, 12 were advertisements, 8 were intraoperative videos documenting the device implantation procedures, 7 of the videos were produced to document personal patient experiences, and 4 were categorized as documentation of a public event. 3 were intended to educate health care workers. The remaining 3 were intended to raise public awareness about sudden cardiac death. The videos portraying intraoperative procedures generated the most “likes” or “dislikes” per view. Conclusion: While YouTube provides a logical platform for delivery of health information, the information on this platform is not regulated. Initiative by reputed authorities and posting accurate information in such platform can be a great aid in public education regarding device therapy. PMID:25077075

    Background How well the 2011 Global Initiative for Chronic Obstructive Lung Disease (GOLD) classification prognosticates for Asian patients with COPD is unknown. Objective The authors aimed to study the predictive utility of the GOLD 2011 classification for exacerbations and mortality as compared with other multidimensional tools in an Asian population. Methods In all, 1,110 COPD patients were prospectively followed between March 2008 and March 2013. They were classified using the 2011 and 2007 GOLD guidelines, modified Medical Research Council score, St. George’s Respiratory Questionnaire (SGRQ), and Body mass index, Obstruction, Dyspnea (BOD) index. Outcome measures were exacerbations and mortality. Multivariable survival analyses and receiver operating characteristic (ROC) curves were used to assess the different classification systems. Results Time-to-event analyses demonstrated earlier exacerbations in 2011’s GOLD D when compared with GOLD A (hazard ratio [HR] 0.54, 95% confidence interval [CI]: 0.31–0.95, P=0.032) and GOLD B (HR 0.62, 95% CI: 0.45–0.85, P=0.003) and higher mortality when compared with GOLD A (HR 0.37, 95% CI: 0.16–0.88, P=0.025) and GOLD B (HR 0.46, 95% CI: 0.31–0.70, P<0.001). The areas under the ROC curve for GOLD 2011, GOLD 2007, modified Medical Research Council, St. George’s Respiratory Questionnaire, and BOD index were 0.62, 0.59, 0.61, 0.60, and 0.61, respectively, for the prediction of exacerbations and 0.71, 0.70, 0.71, 0.71, and 0.72, respectively, for the prediction of mortality (ROC comparator, P>0.05). Conclusion The 2011 GOLD classification predicts exacerbations and mortality moderately well in Asian COPD patients. Its prognostic utility is similar to that of other multidimensional systems.

Smartphones offer an accessible, low-cost means to collect patient symptoms in real time and aid in care. Objective To investigate adherence among psychiatric outpatients diagnosed with major depressive disorder in utilizing their personal smartphones to run a custom app to monitor Patient Health Questionnaire-9 (PHQ-9) depression symptoms, as well as to examine the correlation of these scores to traditionally administered (paper-and-pencil) PHQ-9 scores. Methods A total of 13 patients with major depressive disorder, referred by their clinicians, received standard outpatient treatment and, in addition, utilized their personal smartphones to run the study app to monitor their symptoms. Subjects downloaded and used the Mindful Moods app on their personal smartphone to complete up to three survey sessions per day, during which a randomized subset of PHQ-9 symptoms of major depressive disorder were assessed on a Likert scale. The study lasted 29 or 30 days without additional follow-up. Outcome measures included adherence, measured by the percentage of completed survey sessions, and estimates of daily PHQ-9 scores collected from the smartphone app, as well as from the traditionally administered PHQ-9. Results Overall adherence was 77.78% (903/1161) and varied with time of day. PHQ-9 estimates collected from the app strongly correlated (r=.84) with traditionally administered PHQ-9 scores, but app-collected scores were 3.02 (SD 2.25) points higher on average. More subjects reported suicidal ideation using the app than they did on the traditionally administered PHQ-9. Conclusions Patients with major depressive disorder are able to utilize an app on their personal smartphones to self-assess their symptoms of major depressive disorder with high levels of adherence. These app-collected results correlate with the traditionally administered PHQ-9. Scores

    Background Adjuvant zoledronic acid (za) appears to improve disease-free survival (dfs) in women with early-stage breast cancer and low levels of estrogen (lle) because of induced or natural menopause. Characterizing the cost–utility (cu) of this therapy could help to determine its role in clinical practice. Methods Using the perspective of the Canadian health care system, we examined the cu of adjuvant endocrine therapy with or without za in women with early-stage endocrine-sensitive breast cancer and lle. A Markov model was used to compute the cumulative costs in Canadian dollars and the quality-adjusted life-years (qalys) gained from each adjuvant strategy, discounted at a rate of 5% annually. The model incorporated the dfs and fracture benefits of adjuvant za. Probabilistic and one-way sensitivity analyses were conducted to examine key model parameters. Results Compared with a no-za strategy, adjuvant za in the induced and natural menopause groups was associated with, respectively, $7,825 and $7,789 in incremental costs and 0.46 and 0.34 in qaly gains for cu ratios of $17,007 and $23,093 per qaly gained. In one-way sensitivity analyses, the results were most sensitive to changes in the za dfs benefit. Probabilistic sensitivity analysis suggested a 100% probability of adjuvant za being a cost-effective strategy at a threshold of $100,000 per qaly gained. Conclusions Based on available data, adjuvant za appears to be a cost-effective strategy in women with endocrine-sensitive breast cancer and lle, having cu ratios well below accepted thresholds.

    Autism is a pervasive developmental disorder that affects a growing number of children in the United States each year. It is characterized by substantive differences in brain structure and function that lead to long-term cognitive and social deficits. These differences, combined with the increasing prevalence of autism in children, warrant the need for development of innovative, cost-effective and widely available alternative and complementary therapies. Motion gaming has the potential to be highly efficacious as a therapeutic technique to aid in developing memory, facial recognition, motor skills and social integration in the pediatric autistic population. This paper outlines the major deficits in the brains of individuals with autism and describes how the use of motion gaming could capitalize on the individual strengths of each patient, leading to improvements in a variety of deficits.

    A survey of 8,034 primary care patients in a health maintenance organization examined the relationship between alcohol consumption and health care costs and service use. Costs were estimated from service use data for 1 year before and 2 years after study enrollment. No strong, consistent relationships were identified between multiple indicators of drinking patterns and either health care costs or service use. Compared with total costs among very light drinkers, former drinkers were higher, lifetime abstainers were similar, and persons in the higher drinking levels tended to have lower but not significantly different costs. Drinking patterns did not appear to be an important predictor of short-term health care costs or service use in this setting. Further study of former drinkers is warranted to examine the role of alcohol-related illnesses in the decision to quit drinking. PMID:11732242

    Outcomes assessment is often difficult to accomplish in evaluation research studies in situations where the gathering of pretest data is impossible or prohibitively expensive. The purpose of this longitudinal study was to investigate the substitutability of retrospective pretest ratings for actual pretest ratings in indexing change in patient satisfaction with health status. The sample consisted of 251 women receiving medical treatment for breast cancer enrolled in the Self-Help Intervention Project (SHIP). ANOVA, ordinary least-squares regression, and pooled time-series regression analysis revealed that retrospective assessments were not significantly different from their prospective counterparts in means and variances and that they differed from current assessments taken at the same time (p<.01). In addition, prospective assessments emerged as a significant independent predictor of corresponding retrospective scores (p<.01), accounting for up to 30% of the recall scores. These findings have implications for inclusion of retrospective pre-post comparisons in outcomes evaluation research.

    To determine whether isotype matched immunoglobulin (Ig; Ig′κ/Ig′λ) ratios had prognostic significance in patients with intact Ig multiple myeloma (MM). Novel immunoassays measuring serum concentrations of the Ig heavy chain/light chain (HLC) subsets IgGκ, IgGλ, IgAκ and IgAλ were compared with monoclonal protein (‘M-spike') quantification by serum protein electrophoresis, β2-microglobulin (β2-M), albumin, serum free light chain (FLC) and cytogenetic markers in relation to outcome in 339 MM patients. Abnormal IgGκ/IgGλ and IgAκ/IgAλ ratios present in the respective tumor isotypes at clinical presentation were predictive of shorter progression-free survival (PFS) (hazard ratio (HR) 1.9; P=0.0002), predominantly due to the suppression of the uninvolved (polyclonal) Ig of the same isotype as the tumor (HR 1.8; P=0.002). No significant associations were observed between PFS and M-spike concentrations, suppression of non-tumor Igs of different isotypes or FLC κ/λ ratios. β2-M and HLC ratios were independently prognostic (P=0.045 and P=0.001). A staging system using β2-M and extreme HLC ratios (<0.01 or >200) had greater prognostic value than the widely used ISS staging system (HR 1.7; P=0.00002 vs HR 1.3; P=0.017). These results suggest that HLC ratios may have a role in clinical management of MM. PMID:22699454

    The pattern of distribution of gallium uptake in the thorax was investigated in patients (pts) with AIDS. Eleven pts (ages 18-53), all active homosexual males suspected of having acute pulmonary infection were studied. Ga lung scans were performed at 24-48 and/or 72 hrs. post injection. The diagnosis of AIDS was based on appropriate clinical and laboratory findings. The Ga activity in the lung was graded from zero = background to 4+ which is > liver activity. Eight of eleven pts have positive Ga scan while seven of eleven pts had positive CXR. Six pts had both positive CXR and Ga scan. One pt had a positive Ga scan with negative CXR, and one with positive CXR and negative Ga scan. The positive Ga scans included 3 pts with 4+ diffuse uptake, two pts with 2+ diffuse uptake, two pts with 1+ diffuse uptake, and two with hilar node uptake. Three pts have focal increased uptake superimposed on diffuse uptake. Two pts with 4+ diffuse uptake had mild abnormality on their CXR. One pt with 4+ uptake in the initial scan shows decreased activity on follow-up with clinical improvement after therapy. Thus, all but two pts with positive Ga scans had diffuse lung uptake. These two patients alone had B cell immunoblastic sarcoma and oral candidiasis. The pattern of Ga lung uptake in pts with AIDS reveal that a majority of positive scans are diffuse (6/8) and the intensity may suggest more active disease than CXR (2 normal) and, thus, the study may be useful in detecting changes from atypical pulmonary infection in this population.

    Vascular endothelial growth factor (VEGF), matrix metalloproteinase-9, and tissue inhibitor of metalloproteinase-1 may play a role in the pathogenesis of cancer disease. We investigated their levels and utility in comparison to cancer antigen (CA) 15-3 in patients with breast cancer (BC) and in relation to the control groups. The study included 100 women with BC, 50 patients with benign breast tumor, and 50 healthy women. The plasma levels of the tested parameters were determined using enzyme-linked immunosorbent assay, while CA 15-3 with chemiluminescent microparticle immunoassay. The results demonstrated significant differences in the concentration of the tested parameters and CA 15-3 between groups of patients with BC and healthy patients or patients with benign breast tumor. The plasma levels of VEGF and tissue inhibitor of metalloproteinase-1 were significantly higher in advanced tumor stages. The tested parameters were comparable to CA 15-3 values of the diagnostic sensitivity, specificity, the predictive values of positive and negative test results, and the area under the receiver-operating characteristic curve. The combined use of the tested parameters with CA 15-3 resulted in the increase in sensitivity, negative predictive value, and area under the receiver-operating characteristic curve, especially in the combination of VEGF with tumor marker (84%, 73%, 0.888, respectively). These findings suggest the usefulness of the tested parameters in the diagnosis of BC. VEGF, especially in combination with CA 15-3, showed the highest usefulness in the diagnosis of early BC.

    Purpose Report the results of using a permanently implantable dosimeter in radiation therapy: determine specific adverse events, degree of migration, and acquire dose measurements during treatment to determine difference between expected and measured dose. Methods and Materials DVS (Dose Verification System) is a wireless, permanently implantable MOSFET dosimeter using a bidirectional antenna for power and data transfer. The study cohort includes 36 breast (33 received 2 devices) and 29 prostate (21 received 2 devices) cancer patients. A total of 1783 and 1749 daily dose measurements were obtained on breast and prostate patients, respectively. The measurements were compared to the planned expected dose. Bi-weekly CT scans were obtained to evaluate migration and NCI CTCv3 used to evaluate adverse events. Results Only grade I/II adverse events of pain and bleeding were noted. There were only four instances of dosimeter migration of >5mm due to known factors. A deviation of ≥7% in cumulative dose was noted in 7 of 36 (19%) for breast cancer patients. In prostate cancer patients, a ≥7% deviation was noted in 6 of 29 (21%) and 8 of 19 (42%) during initial and boost irradiation, respectively. The two patterns of dose deviation were random and systematic. Some causes for these differences could involve organ movement, patient movement and/or treatment plan considerations. Conclusions The DVS was not associated with significant adverse events or migration. The dosimeter can measure dose in situ on a daily basis. The accuracy and utility of the DVS complements current IGRT and IMRT techniques. PMID:18793963

    Background and objectives Depressive symptoms and pain are common in patients receiving chronic hemodialysis, yet their effect on dialysis adherence, health resource utilization, and mortality is not fully understood. This study sought to characterize the longitudinal associations of these symptoms with dialysis adherence, emergency department (ED) visits, hospitalizations, and mortality. Design, setting, participants, & measurements As part of a trial comparing symptom management strategies in patients receiving chronic hemodialysis, this study prospectively assessed depressive symptoms using the Patient Health Questionnaire 9, and pain using the Short-Form McGill Pain Questionnaire, monthly between 2009 and 2011. This study used negative binomial, Poisson, and proportional hazards regression to analyze the longitudinal associations of depressive symptoms and pain, scaled based on 5-point increments in symptom scores, with missed and abbreviated hemodialysis treatments, ED visits, hospitalizations, and mortality, respectively. Results Among 286 patients, moderate-to-severe depressive symptoms were identified on 788 of 4452 (18%) assessments and pain was reported on 3537 of 4459 (79%) assessments. Depressive symptoms were independently associated with missed (incident rate ratio [IRR], 1.21; 95% confidence interval [95% CI], 1.10 to 1.33) and abbreviated (IRR, 1.08; 95% CI, 1.03 to 1.14) hemodialysis treatments, ED visits (IRR, 1.24; 95% CI, 1.12 to 1.37), hospitalizations (IRR, 1.19; 95% CI, 1.10 to 1.30), and mortality (IRR, 1.40; 95% CI, 1.11 to 1.77). Pain was independently associated with abbreviated hemodialysis treatments (IRR, 1.03; 95% CI, 1.01 to 1.06) and hospitalizations (IRR, 1.05; 95% CI, 1.00 to 1.10). Severe pain was independently associated with abbreviated hemodialysis treatments (IRR, 1.16; 95% CI, 1.06 to 1.28), ED visits (IRR, 1.58; 95% CI, 1.28 to 1.94), and hospitalizations (IRR, 1.22; 95% CI, 1.03 to 1.45), but not mortality (hazard ratio, 1

    Aim To evaluate the diagnostic accuracy and clinical utility of the fibrosis index based on the four factors (FIB-4), aspartate aminotransferase -to-platelet ratio index (APRI), and aspartate aminotransferase–alanine aminotransferase ratio index (AAR) for predicting liver fibrosis in patients with HBV infection. Methods From January 2006 to December 2010,a total of 1543 consecutive chronic hepatitis B(CHB) patients who underwent liver biopsies were enrolled. FIB-4,APRI, and AAR were calculated.The areas under the receiver-operating characteristic curves (AUROCs) were calculated to assess the diagnostic accuracy of these models.The AUROCs of these models were compared by DeLong’s test.For further comparisons in different studies,the AUROCs were adjusted to conduct Adjusted AUROCs(ADjAUROCs) according to the prevalence of fibrosis stages using the difference between advanced and nonadvanced fibrosis (DANA). Results For prediction of significant fibrosis,severe fibrosis,and cirrhosis,the AUROCs of FIB-4 were 0.646(ADjAUROC 0.717),0.670(ADjAUROC 0.741), and 0.715(ADjAUROC 0.786) respectively;whereas it were 0.656(ADjAUROC 0.727),0.653(ADjAUROC 0.724) and 0.639(ADjAUROC 0.710) for APRI, 0.498(ADjAUROC 0.569),0.548(ADjAUROC 0.619) and 0.573(ADjAUROC 0.644) for AAR. The further comparisons demonstrated that there were no significant differences of AUROCs between FIB-4 and APRI in predicting significant and severe fibrosis(P > 0.05),while FIB-4 was superior to APRI in predicting cirrhosis(P < 0.001). Further subgroup analysis demonstrated that the diagnostic accuracy of FIB-4 and APRI in patients with normal alanine aminotransferase(ALT) were higher than that in patients with elevated ALT. Conclusions The results demonstrated that FIB-4 and APRI are useful for diagnosis of fibrosis. FIB-4 and APRI have similar diagnostic accuracy in predicting significant and severe fibrosis,while FIB-4 is superior to APRI in predicting cirrhosis. The clinical utility of FIB-4 and APRI

    Background Antiretroviral therapy (ART) clinic populations have expanded enormously in the successful Malawi ART scale-up programme. Overcrowding, long waiting times and living far away from the clinic may affect the extent to which patients use their ART clinic for intercurrent illnesses. Methods We interviewed patients of a large urban ART clinic in Blantyre, Malawi, during routine visits about the choice of health care facility during recent illness episodes. Results Out of 346 enrolled adults, mean age 39.8 (range 18-70) years, 54.3% female, 202 (58%) reported one or more illness in the past 6 months, during which 85 (42.1%; 95%-confidence interval: 36.9-47.3%) did not utilize their own clinic. Long distance to the clinic was the main subjective reason, while low education attainment, rural residence, perceived mild illness and dissatisfaction with the ART service were associated with not using their own clinic in multivariate analyses. Of all participants, 83.6% were satisfied with the service provided; only 6.1% were aware of the full service package of the ART clinic. Conclusions ART patients often seek health care outside their own clinic, which may have detrimental effects, and has consequences for ART counseling content and reporting of ART information in health passports.

    Sickle cell nephropathy (SCN) is associated with iron/heme deposition in proximal renal tubules and related acute tubular injury (ATI). Here we report the utility of iron staining in differentiating causes of renal allograft dysfunction in patients with a history of sickle cell disease. Case 1: the patient developed acute allograft dysfunction two years after renal transplant. Her renal biopsy showed ATI, supported by patchy loss of brush border and positive staining of kidney injury molecule-1 in proximal tubular epithelial cells, where diffuse increase in iron staining (2+) was present. This indicated that ATI likely resulted from iron/heme toxicity to proximal tubules. Electron microscope confirmed aggregated sickle RBCs in glomeruli, indicating a recurrent SCN. Case 2: four years after renal transplant, the patient developed acute allograft dysfunction and became positive for serum donor-specific antibody. His renal biopsy revealed thrombotic microangiopathy (TMA) and diffuse positive C4d stain in peritubular capillaries. Iron staining was negative in the renal tubules, implying that TMA was likely associated with acute antibody-mediated rejection (AAMR, type 2) rather than recurrent SCN. These case reports imply that iron staining is an inexpensive but effective method in distinguishing SCN-associated renal injury in allograft kidney from other etiologies. PMID:26697257

    This study investigated the influence of sonar training and experience on the selective attention of experienced and inexperienced operators. The Stroop task was selected as a measure of general selective attention, similar in certain task requirements (attentional allocation) to sonar operation. Across two samples (ns = 32 and 36) and four repeated test sessions groups did not differ significantly in speed or accuracy of Stroop performance. The data suggest that experienced operators do not seem to have developed extraordinary attentional skills and that any attentional skills developed through sonar experience do not generalize to other tasks such as the Stroop.

    AIM To determine healthcare resource utilization and the economic burden associated with wet age-related macular degeneration (AMD) in Thailand METHODS This study included patients diagnosed with wet AMD that were 60 years old or older, and had best corrected visual acuity (BCVA) measured at least two times during the follow-up period. We excluded patients having other eye diseases. Two separate sub-studies were conducted. The first sub-study was a retrospective cohort study; electronic medical charts were reviewed to estimate the direct medical costs. The second sub-study was a cross-sectional survey estimating the direct non-medical costs based on face-to-face interviews using a structured questionnaire. For the first sub-study, direct medical costs, including the cost of drugs, laboratory, procedures, and other treatments were obtained. For the second sub-study, direct non-medical costs, e.g. transportation, food, accessories, home renovation, and caregiver costs, were obtained from face-to-face interviews with patients and/or caregivers. RESULTS For the first sub-study, sixty-four medical records were reviewed. The annual average number of medical visits was 11.1±6.0. The average direct medical costs were $3 604±4 530 per year. No statistically-significant differences of the average direct medical costs among the BCVA groups were detected (P=0.98). Drug costs accounted for 77% of total direct medical costs. For direct non-medical costs, 67 patients were included. Forty-eight patients (71.6%) required the accompaniment of a person during the out-patient visit. Seventeen patients (25.4%) required a caregiver at home. The average direct non-medical cost was $2 927±6 560 per year. There were no statistically-significant differences in the average costs among the BCVA groups (P=0.74). Care-giver cost accounted for 87% of direct non-medical costs. CONCLUSION Our study indicates that wet AMD is associated with a substantial economic burden, especially concerning

    The hypothesis in the conceptual model was that a user-driven innovation in presently available information and communication technology infrastructure would be able to meet patient and health professional users information needs and help them attain better health outcomes. An operational model was created to plan a trial on a sample diabetic population utilizing a randomized control trial design, assigning one randomly selected group of diabetics to receive electronic information intervention and analyse if it would improve their health outcomes in comparison with a matched diabetic population who would only receive regular medical intervention. Diabetes was chosen for this particular trial, as it is a major chronic illness in Malaysia as elsewhere in the world. It is in essence a position paper for how the study concept should be organized to stimulate wider discussion prior to beginning the study.

    Objective MicroRNAs (miRNAs) are small non-coding RNAs that post-transcriptionally regulate gene expression and serve as potential mediators and markers of disease. Recently, plasma miR-24-3p and miR-125a-5p concentrations were shown to be elevated in rheumatoid arthritis (RA) and useful for RA diagnosis. We assessed the utility of seven candidate plasma miRNAs, selected for biological relevance, for RA diagnosis and use as markers of disease activity and subclinical atherosclerosis in RA. Methods The cross-sectional study included 168 patients with RA and 91 control subjects, of similar age, race and sex. Plasma concentrations of miR-15a-5p, miR-24-3p, miR-26a-5p, miR-125a-5p, miR-146a-5p, miR-155-5p, and miR-223-3p were measured by quantitative PCR. Utility of plasma miRNA concentrations for RA diagnosis was assessed by area under the receiver operating characteristic curve (AUROC). Association between plasma miRNA concentrations and RA disease activity and coronary artery calcium score were assessed by Spearman correlations. Results Plasma concentrations of miR-15a-5p, 24-3p, miR-26a-5p, miR-125a-5p, miR-146a-5p, miR-155-5p, and miR-223-3p were significantly increased in patients with RA. miR-24-3p had the highest AUROC for diagnosis of RA (AUROC=0.725), including among rheumatoid factor negative patients (AUROC=0.772). Among all patients with RA, the combination of miR-24-3p, miR-26a-5p and miR-125a-5p improved the model modestly (AUROC=0.747). miR-155-5p was weakly inversely associated with swollen joint count (P=0.024), but no other miRNAs were associated with disease activity or coronary artery calcium score. Conclusion The combination of miR-24-3p, miR-26a-5p and miR-125a-5p had strongest diagnostic accuracy for RA. Candidate miRNAs had little or no association with RA disease activity or subclinical atherosclerosis. PMID:26233505

  7. A cost-utility analysis of drug treatments in patients with HBeAg-positive chronic hepatitis B in Thailand

    2014-01-01

    Background Only lamivudine has been included for patients with chronic hepatitis B (CHB) in the National List of Essential Drugs (NLED), a pharmaceutical reimbursement list in Thailand. There have also been no economic evaluation studies of CHB drug treatments conducted in Thailand yet. In order to fill this gap in policy research, the objective of this study was to compare the cost-utility of each drug therapy (Figure 1) with palliative care in patients with HBeAg-positive CHB. Methods A cost-utility analysis using an economic evaluation model was performed to compare each drug treatment for HBeAg-positive CHB patients. A Markov model was used to estimate the relevant costs and health outcomes during a lifetime horizon based on a societal perspective. Direct medical costs, direct non-medical costs, and indirect costs were included, and health outcomes were denoted in life years (LYs) and quality-adjusted life years (QALYs). The results were presented as an incremental cost effectiveness ratio (ICER) in Thai baht (THB) per LY or QALY gained. One-way sensitivity and probabilistic sensitivity analyses were applied to investigate the effects of model parameter uncertainties. Results The ICER values of providing generic lamivudine with the addition of tenofovir when drug resistance occurred, generic lamivudine with the addition of tenofovir based on the road map guideline, and tenofovir monotherapy were -14,000 (USD -467), -8,000 (USD -267) , and -5,000 (USD -167) THB per QALY gained, respectively. However, when taking into account all parameter uncertainties in the model, providing generic lamivudine with the addition of tenofovir when drug resistance occurred (78% and 75%) and tenofovir monotherapy (18% and 24%) would yield higher probabilities of being cost-effective at the societal willingness to pay thresholds of 100,000 (USD 3,333) and 300,000 (USD 10,000) THB per QALY gained in Thailand, respectively. Conclusions Based on the policy recommendations from this

    Background Nonalcoholic fatty liver disease (NAFLD) is common in adults with extreme obesity and can impact long-term health and survival. Liver biopsy is the only accurate test for diagnosis and staging, but is invasive and costly. Non-invasive testing offers an attractive alternate, but the overall accuracy remains a significant issue. This study was conducted to determine the accuracy and clinical utility of preoperative ultrasound and liver transaminase levels, as well as intra-operative hepatic visual inspection, for assessing presence of NAFLD as confirmed by hepatic histology. Methods Data was collected prospectively from 580 morbidly obese adult patients who underwent Roux-en-Y gastric bypass surgery with intraoperative wedge biopsy between January 2004 and February 2009. Complete data for ultrasound, ALT and AST levels, and documented visual inspection was available for 513 patients. Results The prevalence of NAFLD was 69 % and that of NASH was 32 %. The individual non-invasive clinical assessments demonstrated low sensitivity, specificity, and accuracy for detecting the presence of steatosis, steatohepatitis, or fibrosis. The combination of normal or abnormal results for all tests improved predictive utility. Abnormal tests with all three assessments had a sensitivity of 95–98 % and a specificity of 28–48 % for major histologic findings in NAFLD/NASH. Normal tests with all three assessments had a sensitivity of 12–22 % and a specificity of 89–97 % for major histologic findings in NAFLD/NASH. Conclusions Although individual clinical tests for NAFLD have limited accuracy, the use of combined clinical tests may prove useful. PMID:26003548

Methods Following institution of a clinical practice guideline for management of post-operative chylothorax at a single center, pediatric cardiothoracic intensive care unit (ICU) in June 2010, we retrospectively analyzed two cohorts of patients: those with chylothorax from 1/2008-5/2010 (early cohort; n = 118) and from 6/2010-8/2011 (late cohort; n = 45). Data collected included demographics, cardiac surgical procedure, treatments for chylothorax, bloodstream infections, hospital mortality, length of hospitalization, duration of mechanical ventilation, and device utilization. Results There were no demographic differences between the cohorts. No differences were found in octreotide use or surgical treatments for chylothorax. Significant differences were found in median times to chylothorax diagnosis (9 in early cohort versus 6 days in late cohort, p = 0.004), ICU length of stay (18 vs. 9 days, p = 0.01), hospital length of stay (30 vs. 23 days, p = 0.005), and total durations of mechanical ventilation (11 vs. 5 days, p = 0.02), chest tube use (20 vs. 14 days, p = 0.01), central venous line use (27 vs. 15 days, p = 0.001), and NPO status (9.5 vs. 6 days, p = 0.04). Conclusions Institution of a clinical practice guideline for treatment of chylothorax following congenital heart surgery was associated with earlier diagnosis, reduced hospital length of stay, mechanical ventilation, and device utilization for these patients.

    The goal of this study was to determine the prognostic utility of the exercise thallium-201 stress test in ambulatory patients with chest pain who were also referred for cardiac catheterization. Accordingly, 4 to 8 year (mean +/- 1SD, 4.6 +/- 2.6 years) follow-up data were obtained for all but one of 383 patients who underwent both exercise thallium-201 stress testing and cardiac catheterization from 1978 to 1981. Eighty-three patients had a revascularization procedure performed within 3 months of testing and were excluded from analysis. Of the remaining 299 patients, 210 had no events and 89 had events (41 deaths, nine nonfatal myocardial infarctions, and 39 revascularization procedures greater than or equal to 3 months after testing). When all clinical, exercise, thallium-201, and catheterization variables were analyzed by Cox regression analysis, the number of diseased vessels (when defined as greater than or equal to 50% luminal diameter narrowing) was the single most important predictor of future cardiac events (chi 2 = 38.1) followed by the number of segments demonstrating redistribution on delayed thallium-201 images (chi 2 = 16.3), except in the case of nonfatal myocardial infarction, for which redistribution was the most important predictor of future events. When coronary artery disease was defined as 70% or greater luminal diameter narrowing, the number of diseased vessels significantly (p less than .01) lost its power to predict events (chi 2 = 14.5). Other variables found to independently predict future events included change in heart rate from rest to exercise (chi 2 = 13.0), ST segment depression on exercise (chi 2 = 13.0), occurrence of ventricular arrhythmias on exercise (chi 2 = 5.9), and beta-blocker therapy (chi 2 = 4.3).

    Background Biologic disease-modifying antirheumatic drugs (bDMARDs) extend the treatment choices for rheumatoid arthritis patients with suboptimal response or intolerance to conventional DMARDs. The objective of this systematic review and meta-analysis was to compare the relative efficacy of EU-licensed bDMARD combination therapy or monotherapy for patients intolerant of or contraindicated to continued methotrexate. Methods Comprehensive, structured literature searches were conducted in Medline, Embase, and the Cochrane Library, as well as hand-searching of conference proceedings and reference lists. Phase II or III randomized controlled trials reporting American College of Rheumatology (ACR) criteria scores of 20, 50, and 70 between 12 and 30 weeks’ follow-up and enrolling adult patients meeting ACR classification criteria for rheumatoid arthritis previously treated with and with an inadequate response to conventional DMARDs were eligible. To estimate the relative efficacy of treatments whilst preserving the randomized comparisons within each trial, a Bayesian network meta-analysis was conducted in WinBUGS using fixed and random-effects, logit-link models fitted to the binomial ACR 20/50/70 trial data. Results The systematic review identified 10,625 citations, and after a review of 2450 full-text papers, there were 29 and 14 eligible studies for the combination and monotherapy meta-analyses, respectively. In the combination analysis, all licensed bDMARD combinations had significantly higher odds of ACR 20/50/70 compared to DMARDs alone, except for the rituximab comparison, which did not reach significance for the ACR 70 outcome (based on the 95% credible interval). The etanercept combination was significantly better than the tumor necrosis factor-α inhibitors adalimumab and infliximab in improving ACR 20/50/70 outcomes, with no significant differences between the etanercept combination and certolizumab pegol or tocilizumab.

    A qualitative study aimed at describing the situations experienced and the ethical dilemmas of nurses in the process of referring and receiving hospitalized patients by court order who require admission to the Intensive Care Unit (ICU). A partially structured interview was conducted with 10 nurses who worked in the ICU and 10 who worked in the Emergency Room (ER) in public and private hospitals in the metropolitan area of Porto Alegre, Brazil. The data was analyzed following the Semantic Analysis. The results indicated that nurses experienced ethical dilemmas associated with problems of overcrowding in emergency rooms and ICUs, poor specialized technology and orientation as to the benefits provided by law. We concluded that it is essential for nurses to participate in discussions that allow the planning of the different instances that have been promoting this often chaotic situation.

    2013-01-01

    To perform a systematic review of the utility of the Beck Depression Inventory for detecting depression in medical settings, this article focuses on the revised version of the scale (Beck Depression Inventory-II), which was reformulated according to the DSM-IV criteria for major depression. We examined relevant investigations with the Beck Depression Inventory-II for measuring depression in medical settings to provide guidelines for practicing clinicians. Considering the inclusion and exclusion criteria seventy articles were retained. Validation studies of the Beck Depression Inventory-II, in both primary care and hospital settings, were found for clinics of cardiology, neurology, obstetrics, brain injury, nephrology, chronic pain, chronic fatigue, oncology, and infectious disease. The Beck Depression Inventory-II showed high reliability and good correlation with measures of depression and anxiety. Its threshold for detecting depression varied according to the type of patients, suggesting the need for adjusted cut-off points. The somatic and cognitive-affective dimension described the latent structure of the instrument. The Beck Depression Inventory-II can be easily adapted in most clinical conditions for detecting major depression and recommending an appropriate intervention. Although this scale represents a sound path for detecting depression in patients with medical conditions, the clinician should seek evidence for how to interpret the score before using the Beck Depression Inventory-II to make clinical decisions.

    Background Inflammation is an important factor in the pathogenesis of calcific aortic stenosis (AS). We aimed to evaluate the association between an inflammatory marker, neutrophil-to-lymphocyte ratio (NLR) and major adverse cardiovascular events (MACE) in patients with severe calcific AS. Methods A total of 336 patients with isolated severe calcific AS newly diagnosed between 2010 and 2015 were enrolled in this study. Using Cox proportional hazards (PH) regression models, we investigated the prognostic value of NLR adjusted for baseline covariates including logistic European System for Cardiac Operative Risk Evaluation score (EuroSCORE-I) and undergoing aortic valve replacement (AVR). We also evaluated the clinical relevance of NLR risk groups (divided into low, intermediate, high risk) as categorized by NLR cutoff values. MACE was defined as a composite of all-cause mortality, cardiac death and non-fatal myocardial infarction during the follow-up period. Results The inflammatory marker NLR was an independent prognostic factor most significantly associated with MACE [hazard ratio (HR), 1.06; 95% confidence interval (CI), 1.04–1.09; p-value <0.001]. The goodness-of-fit and discriminability of the model including EuroSCORE-I and AVR (loglikelihood difference, 15.49; p-value <0.001; c-index difference, 0.035; p-value = 0.03) were significantly improved when NLR was incorporated into the model. The estimated Kaplan-Meier survival rates at 5 years for the NLR risk groups were 84.6% for the low risk group (NLR ≤ 2), 67.7% for the intermediate risk group (2 < NLR ≤ 9), and 42.6% for the high risk group (NLR > 9), respectively. Conclusion The findings of the present study demonstrate the potential utility of NLR in risk stratification of patients with severe calcific AS. PMID:27548384

    Objective The Beck Depression Inventory (BDI) is often used to assess depression symptoms, but its factor structure and clinical utility have not been evaluated in patients with binge eating disorder (BED) and obesity. Methods 882 treatment-seeking obese patients with BED were administered structured interviews (SCID-I/P) and completed self-report questionnaires. Results Exploratory and confirmatory factor analyses supported a brief 16-item BDI version with a three-factor structure (affective, attitudinal, and somatic). Both 21- and 16-item versions showed excellent internal consistency (both α=0.89) and had significant correlation patterns with different aspects of eating disorder psychopathology; three factors showed significant but variable associations with eating disorder psychopathology. Area under the curves (AUC) for both BDI versions were significant in predicting major depressive disorder (MDD; AUC=0.773 [16-item], 73.5% sensitivity/70.2% specificity, AUC=0.769 [21-item], 79.5% sensitivity/64.1% specificity) and mood disorders (AUC=0.763 [16-item], 67.1% sensitivity/71.5% specificity, AUC=0.769 [21-item], 84.2% sensitivity/55.7% specificity). 21-item BDI (cut-off score ≥16) showed higher negative predictive values (94.0% vs. 93.0% [MDD]; 92.4% vs. 88.3% [mood disorders]) than brief 16-item BDI (cut-off score ≥13). Conclusions Both BDI versions demonstrated moderate performance as a screening instrument for MDD/mood disorders in obese patients with BED. Advantages and disadvantages for both versions are discussed. A three-factor structure has potential to inform the conceptualization of depression features. PMID:25537344

    In an effort to lower healthcare costs, this study was undertaken to evaluate the utility of routine postoperative (PO) laboratory studies and determine whether abnormalities alter patient (PT) care. This was a retrospective review of 105 PTs undergoing elective curative resection for colorectal cancer. A serum electrolyte and liver panel and a hematologic panel were drawn in all PTs. OF 8749 total laboratory values obtained, 5894 (67%) were normal. Two of these (0.03%) elicited a therapeutic intervention. Of the 2004 values that were low (23%), 103 (5.1%) elicited a therapeutic response. Of the 851 that were high (10%), 21 (2.5%) elicited a therapeutic response. Of 2089 preoperative laboratory values, 252 (12%) were abnormal, but in only 15 incidences in 9 PTs was any action taken. Three PTs required potassium supplementation and 6 PTs were transfused packed red blood cells before surgery. In the PO period 2603 laboratory values of 6660 obtained (39%) were abnormal. Of these, 735 (28%) were high and 1868 (72%) were low. Twenty of 735 (27%) high values triggered a therapeutic response that most commonly required administration of insulin for elevated serum glucose in 17 of 197 occasions in five diabetic PTs. On three occasions potassium was removed from intravenous fluids. Five of 275 (1.8%) low calcium values were treated in five patients. Potassium was replaced in 17 of 32 occasions in 14 patients where it was low. In this group of PTs, PO serum potassium, hemoglobin levels, and serum glucose in diabetics were the only values important in making therapeutic decisions. If laboratory studies can be streamlined into only those necessary, substantial savings in health care will be seen without sacrificing quality medical care.

    The purpose of this study was to analyze the influence of radiographic arterial calcification (RAC) on the clinical interpretation of ankle-brachial index (ABI) values in patients with diabetic foot ulcers. We analyzed a retrospective clinical database of 60 patients with diabetic foot ulcers from the Diabetic Foot Unit (Complutense University, Madrid, Spain) between January 2012 and March 2014. For each patient, anteroposterior XR-plains were evaluated, and the ABI and toe-brachial index (TBI) were assessed by an experienced clinician. To analyze the correlation among quantitative variables, we applied the Pearson correlation coefficient. Fifty percent (n = 9/18) of our patients with a normal ABI and RAC had a TBI < 0.7 associated with peripheral arterial disease (PAD). In patients with RAC, the prevalence of a normal ABI (72%, 18/25) was higher than in patients without RAC (52%, 11/21). The Pearson correlation coefficient among the ABI and TBI in patients with an ABI < 1.4 (n = 46) was lesser (r = .484, P = .001) than in patients with an ABI < 1.4 but without RAC (n = 21; r = .686, P = .001). ABI values between 0.9 and 1.4 would be falsely considered as normal and could underestimate the prevalence of PAD, especially in patients with neuropathy, diabetic foot ulcers, or RAC.

    Purpose. Pain is multi-dimensional and may be better addressed through a holistic, biopsychosocial approach. Massage therapy is commonly practiced among patients seeking pain management; however, its efficacy is unclear. This systematic review and meta-analysis is the first to rigorously assess the quality of massage therapy research and evidence for its efficacy in treating pain, function-related and health-related quality of life outcomes across all pain populations. Methods. Key databases were searched from inception through February 2014. Eligible randomized controlled trials were assessed for methodological quality using SIGN 50 Checklist. Meta-analysis was applied at the outcome level. A diverse steering committee interpreted the results to develop recommendations. Results. Sixty high quality and seven low quality studies were included in the review. Results demonstrate massage therapy effectively treats pain compared to sham [standardized mean difference (SMD) = −.44], no treatment (SMD = −1.14), and active (SMD = −0.26) comparators. Compared to active comparators, massage therapy was also beneficial for treating anxiety (SMD = −0.57) and health-related quality of life (SMD = 0.14). Conclusion. Based on the evidence, massage therapy, compared to no treatment, should be strongly recommended as a pain management option. Massage therapy is weakly recommended for reducing pain, compared to other sham or active comparators, and improving mood and health-related quality of life, compared to other active comparators. Massage therapy safety, research challenges, how to address identified research gaps, and necessary next steps for implementing massage therapy as a viable pain management option are discussed.

    The aim of the study was to assess health-related quality of life (HRQoL) among metastatic soft tissue (mSTS) or bone sarcoma (mBS) patients who had attained a favourable response to chemotherapy. We employed the EORTC QLQ-C30, the 3-item Cancer-Related Symptoms Questionnaire, and the EQ-5D instrument. HRQoL was evaluated overall and by health state in 120 mSTS/mBS patients enrolled in the SABINE study across nine countries in Europe and North America. Utility was estimated from responses to the EQ-5D instrument using UK population-based weights. The mean EQ-5D utility score was 0.69 for the pooled patient sample with little variation across health states. However, patients with progressive disease reported a clinically significant lower utility (0.56). Among disease symptoms, pain and respiratory symptoms are common. This study showed that mSTS/mBS is associated with reduced HRQoL and utility among patients with metastatic disease.

    In primary care medicine, establishing a diagnosis of influenza and respiratory syncytial virus (RSV) infections is usually based on clinical history and physical examination as well as a consideration of time of the year and circulating respiratory viruses in the community. Methods: We tested the potential clinical samples using the automated molecular assay which included rapid influenza diagnostic test, Rapid Immunochromatographic Antigen Test, Verigene Respiratory Virus Plus Nucleic Acid Test, BD VeritorTM System for Rapid Detection of RSV in the paediatric setting for diagnosis of influenza and respiratory syntactical virus infections when testing was done by the paediatrician seeing the patient. Results: Principally, with respect influenza virus specificity and sensitivity for RIAT were 100% and 68.8%; compared to 100% and 100%, respectively for RV+. The specificity and sensitivity for 92.23% and 98% for BD VeritorTM System for Rapid Detection of RSV as compared to 96.6% and 98.42% for RIDT. Conclusion: Therefore, this study confirms the clinical utility of RV+ in the pediatric setting. PMID:26629177

    Adult patients with symptoms connected to the trauma of childhood sexual abuse often present in therapy with multiple symptoms and life difficulties and offer a challenge to even the most experienced clinician. In this paper, I describe my work with three such patients who were crippled in different ways by symptoms that had proved resistant to years of various therapeutic interventions. In every case, I accepted and utilized these symptoms as positive resources for successful and rapid change. Patients were then taught self-utilization approaches which allowed them to sustain and extend initial improvements. I conclude that the indirect utilization principle introduced by Milton Erickson provides an effective method to use in approaching some of the more persistent patterns of posttraumatic symptomatology related to childhood sexual abuse.

    Objective The objective of this study was to describe and analyze the effects of depression on health care utilization and costs in a sample of multimorbid elderly patients. Method This cross-sectional analysis used data of a prospective cohort study, consisting of 1,050 randomly selected multimorbid primary care patients aged 65 to 85 years. Depression was defined as a score of six points or more on the Geriatric Depression Scale (GDS-15). Subjects passed a geriatric assessment, including a questionnaire for health care utilization. The impact of depression on health care costs was analyzed using multiple linear regression models. A societal perspective was adopted. Results Prevalence of depression was 10.7%. Mean total costs per six-month period were €8,144 (95% CI: €6,199-€10,090) in patients with depression as compared to €3,137 (95% CI: €2,735-€3,538; p<0.001) in patients without depression. The positive association between depression and total costs persisted after controlling for socio-economic variables, functional status and level of multimorbidity. In particular, multiple regression analyses showed a significant positive association between depression and pharmaceutical costs. Conclusion Among multimorbid elderly patients, depression was associated with significantly higher health care utilization and costs. The effect of depression on costs was even greater than reported by previous studies conducted in less morbid patients. PMID:24638040

    ABSTRACT Individuals differ in thermosensitivity, thermoregulation, and zones of thermoneutrality and thermal comfort. Whereas temperature sensing and -effectuating processes occur in part unconsciously and autonomic, awareness of temperature and thermal preferences can affect thermoregulatory behavior as well. Quantification of trait-like individual differences of thermal preferences and experienced temperature sensitivity and regulation is therefore relevant to obtain a complete understanding of human thermophysiology. Whereas several scales have been developed to assess instantaneous appreciation of heat and cold exposure, a comprehensive scale dedicated to assess subjectively experienced autonomic or behavioral thermoregulatory activity has been lacking so far. We constructed a survey that specifically approaches these domains from a trait-like perspective, sampled 240 volunteers across a wide age range, and analyzed the emergent component structure. Participants were asked to report their thermal experiences, captured in 102 questions, on a 7-point bi-directional Likert scale. In a second set of 32 questions, participants were asked to indicate the relative strength of experiences across different body locations. Principal component analyses extracted 21 meaningful dimensions, which were sensitive to sex-differences and age-related changes. The questions were also assessed in a matched sample of 240 people with probable insomnia to evaluate the sensitivity of these dimensions to detect group differences in a case-control design. The dimensions showed marked mean differences between cases and controls. The survey thus has discriminatory value. It can freely be used by anyone interested in studying individual or group differences in thermosensitivity and thermoregulation. PMID:27227080

    In 2009, Elena Long created the LGBT+ Physicists website (http://lgbtphysicists.x10hosting.com) as a warehouse for resources useful for sexual and gender minorities working in physics. This resource has grown to include networking resources, lists of LGBT-friendly universities and localities, recommendations for enacting positive change in physics communities, and out-reach to other STEM-oriented LGBT organizations. This has been possible in large part by the dynamic community of LGBT+ physicists and allies looking to make physics more welcoming towards our community. In 2011, Elena used hir position as Member at Large on the executive committee of the Forum of Graduate Student Affairs (FGSA) to conduct a climate survey that included, among other things, the first serious look at LGBT+ demographics in physics. The survey focused particularly on issues of language heard and harassment experienced by physicists and was broken down into categories based on race, physical and mental ability, gender, and sexuality. Furthermore, it examined the outcomes of experienced harassment and the reasons for when harassment was not reported. Due to the nature of the study, overlapping demographics, especially ``multiple minorities,'' were also explored. This talk will give a brief history of the LGBT+ Physicists resource as well as an overview of the FGSA study.

    Aim To describe practicing physicians’ perceived clinical utility of genome sequencing. Materials & methods We conducted a mixed-methods analysis of data from 18 primary care physicians and cardiologists in a study of the clinical integration of whole-genome sequencing. Physicians underwent brief genomics continuing medical education before completing surveys and semi-structured interviews. Results Physicians described sequencing as currently lacking clinical utility because of its uncertain interpretation and limited impact on clinical decision-making, but they expressed the idea that its clinical integration was inevitable. Potential clinical uses for sequencing included complementing other clinical information, risk stratification, motivating patient behavior change and pharmacogenetics. Conclusion Physicians given genomics continuing medical education use the language of both evidence-based and personalized medicine in describing the utility of genome-wide testing in patient care.

    2009-01-01

    Hot flashes occur frequently in menopausal women and in women with breast cancer, diminishing their quality of life. A report from the Women's Health Initiative published in 2002 raised concerns about the long-term safety of estrogen therapy. As a result, nonhormonal alternatives have emerged as preferred treatments. Gabapentin is an anticonvulsant that the United States Food and Drug Administration approved as an adjunct therapy for partial seizures and postherpetic neuralgia. Somnolence, dizziness, ataxia, fatigue, nystagmus, and peripheral edema are adverse effects commonly associated with gabapentin in the treatment of epilepsy and postherpetic neuralgia. The North American Menopause Society and the American College of Obstetricians and Gynecologists recommend the use of gabapentin as an option for managing hot flashes in women who are unwilling to take estrogen-containing supplements. To evaluate the efficacy and safety of gabapentin for the treatment of hot flashes in women with menopause and/or breast cancer, we performed a search of the MEDLINE database (1966-March 2008) and International Pharmaceutical Abstracts, as well as manually searching reference articles for relevant articles and abstracts; 10 clinical studies were identified. Although the studies were few, all showed gabapentin to be safe and effective in the treatment of hot flashes. At doses used to control hot flashes, gabapentin was well tolerated, with drowsiness as its most reported adverse effect. Gabapentin can be considered effective in the treatment of hot flashes and should be considered a reasonable alternative when estrogen therapy is not desired. PMID:19113798

    Premature ovarian failure (POF) is a condition in which the ovarian functions of hormone production and oocyte development become impaired before the typical age for menopause. POF and early menopause are present in a broad spectrum of gonad dysgenesis, from a complete cessation of ovarian function to an intermittent follicle maturation failure. Actually POF has been identified as a genetic entity (especially chromosome X), but data on genetic factors of premature menopause are limited. Until now, several cases revealed that inactivation of X chromosomes has an effect on ages of premature menopause and females with balanced or unbalanced X-autosome translocations can have several reproductive problems. On the other hand, there have been a few data that was caused by autosome-autosome translocation can lead. Therefore we report a relevant case of POF with translocation between chromosomes 1 and 4. She had her first menstrual period at the age of 12, and after 7 years she stopped menstruation. Chromosomal analysis showed 46, XX, t (1;4) (p22.3;q31.3). While evaluating this rare case, we could review various causes (especially genetic factors) of POF. To remind clinicians about this disease, we report a case of POF caused by autosome-autosome translocation with a literature review. PMID:26356509

    Background Diabetes has a high burden of illness both in life years lost and in disability through related co-morbidities. Accurate assessment of the non-mortality burden requires appropriate health-related quality of life and summary utility measures of which there are several contenders. The study aimed to measure the impact of diabetes on various health-related quality of life domains, and compare several summary utility measures. Methods In the ADVANCE (Action in Diabetes and Vascular Disease: Preterax and Diamicron MR Controlled Evaluation) study, 978 Australian patients with Type 2 diabetes completed two health-related quality of life questionnaires at baseline: the EQ-5D and the SF-36v2, from which nine summary utility measures were calculated, and compared. The algorithms were grouped into four classes: (i) based on the EQ-5D; (ii) using fewer items than those in the SF-12 (iii) using the items in the SF-12; and (iv) using all items of the SF-36. Results Overall health-related quality of life of the subjects was good (mean utility ranged from 0.68 (±0.08) to 0.85(±0.14) over the nine utility measures) and comparable to patients without diabetes. Summary indices were well correlated with each other (r = 0.76 to 0.99), and showed lower health-related quality of life in patients with major diabetes-related events such as stroke or myocardial infarction. Despite the smaller number of items used in the scoring of the EQ-5D, it generally performed at least as well as SF-36 based methods. However, all utility measures had some limitation such as limited range or ceiling effects. Conclusion The summary utility measures showed good agreement, and showed good discrimination between major and minor health state changes. However, EQ-5D based measures performed as well and are generally simpler to use. PMID:17462100

    Background: Data on the use of emergency medical services (EMS) by patients with cardiac conditions in the Gulf region are scarce, and prior studies have suggested underutilization. Patient perception and knowledge of EMS care is critical to proper utilization of such services. Objectives: To estimate utilization, knowledge, and perceptions of EMS among patients with ST-elevation myocardial infarction (STEMI) in the Emirate of Abu Dhabi. Methods: We conducted a multicenter prospective study of consecutive patients admitted with STEMI in four government-operated hospitals in Abu Dhabi. Semi-structured interviews were conducted with patients to assess the rationale for choosing their prehospital mode of transport and their knowledge of EMS services. Results: Of 587 patients with STEMI (age 51 ± 11 years, male 95%), only 15% presented through EMS, and the remainder came via private transport. Over half of the participants (55%) stated that they did not know the telephone number for EMS. The most common reasons stated for not using EMS were that private transport was quicker (40%) or easier (11%). A small percentage of participants (7%) did not use EMS because they did not think their symptoms were cardiac-related or warranted an EMS call. Stated reasons for not using EMS did not significantly differ by age, gender, or primary language of the patients. Conclusions: EMS care for STEMI is grossly underutilized in Abu Dhabi. Patient knowledge and perceptions may contribute to underutilization, and public education efforts are needed to raise their perception and knowledge of EMS. PMID:27512532

  3. Is binge eating experienced as an addiction?

    2007-11-01

    To ascertain to what degree binge eating is experienced as an addiction, this study examined the proportion of women with binge-eating disorder (BED) whose symptoms met criteria for an addiction. Women (N = 79) with current BED completed a structured telephone interview to assess for symptoms of a modified version of DSM-IV substance dependence and Goodman's [(1990). Addiction: Definition and implications. British Journal of Addiction, 85, 1403-1408] proposed diagnosis of 'addictive disorder'. Most binge eaters (92.4%) met modified DSM-IV criteria for substance dependence, whereas many fewer (40.5%) met Goodman's more restrictive criteria for addictive disorder. Women meeting criteria for addictive disorder had more frequent eating binges than those who did not. Despite certain observed similarities between binge eating and addictions, we argue that BED should remain classified as an eating disorder.

    The objective of this study is to determine the catheter-related bloodstream infection (CRBSI) rate in a severely burned patient population, many of whom required prolonged use of central venous catheters (CVCs). Between January 2008 and June 2012, 151 patients underwent placement of 455 five-lumen minocycline/rifampin-impregnated CVCs. CRBSI was defined as at least one blood culture (>100,000 colonies) and one simultaneous roll-plate CVC tip culture (>15 colony forming units) positive for the same organism. Most patients had accidental burns (81.5%) with a mean TBSA of 50%. A mean of three catheters were inserted per patient (range, 1-25). CVCs were inserted in the femoral vein (91.2%), subclavian vein (5.3%), and internal jugular vein (3.3%). Mean overall catheter indwell time was 8 days (range, 0-39 days). The overall rate of CRBSI per 1000 catheter days was 11.2; patients with a TBSA >60% experienced significantly higher rates of CRBSI than patients with a TBSA ≤60% (16.2 vs 7.3, P = .01). CVCs placed through burned skin were four times more likely to be associated with CRBSI than CVCs placed through intact skin. The most common infectious organism was Acinetobacter baumannii. Deep venous thrombosis developed in eleven patients (7%). The overall rate of CRBSI was 11.2, consistent with published rates of CRBSI in burn patients. Thus, femoral placement of 5-lumen CVCs did not result in increased CRBSI rates. These data support the safety of femoral CVC placement in burn patients, contrary to the Centers for Disease Control recommendation to avoid femoral CVC insertion.

    Objective To assess the cost‐effectiveness and cost‐utility of Spinal Cord Stimulation (SCS) in patients with failed back surgery syndrome (FBSS) refractory to conventional medical management (CMM). Materials and Methods We conducted an observational, multicenter, longitudinal ambispective study, where patients with predominant leg pain refractory to CMM expecting to receive SCS+CMM were recruited in 9 Italian centers and followed up to 24 months after SCS. We collected data on clinical status (pain intensity, disability), Health‐Related Quality‐of‐Life (HRQoL) and on direct and indirect costs before (pre‐SCS) and after (post‐SCS) the SCS intervention. Costs were quantified in € 2009, adopting the National Health Service's (NHS), patient and societal perspectives. Benefits and costs pre‐SCS versus post‐SCS were compared to estimate the incremental cost‐effectiveness and cost utility ratios. Results 80 patients (40% male, mean age 58 years) were recruited. Between baseline and 24 months post‐SCS, clinical outcomes and HRQoL significantly improved. The EQ‐5D utility index increased from 0.421 to 0.630 (p < 0.0001). Statistically significant improvement was first observed six months post‐SCS. Societal costs increased from €6600 (pre‐SCS) to €13,200 (post‐SCS) per patient per year. Accordingly, the cost‐utility acceptability curve suggested that if decision makers' willingness to pay per Quality‐Adjusted‐Life‐Years (QALYs) was €60,000, SCS implantation would be cost‐effective in 80% and 85% of cases, according to the NHS's and societal point of views, respectively. Conclusions Our results suggest that in clinical practice, SCS+CMM treatment of FBSS patients refractory to CMM provides good value for money. Further research is encouraged in the form of larger, long‐term studies. PMID:25879722

    To provide financial protection against catastrophic illness, the Korean government expanded the National Health Insurance (NHI) benefit coverage for cancer patients in 2005. This paper examined whether the policy improved the income-related equality in health care utilization. This study analyzed the extent to which the policy improved income-related equality in outpatient visits, inpatient days, and inpatient and outpatient care expenditure based on triple difference estimator. Using nationwide claims data of the NHI from 2002 to 2004 and from 2006 to 2010, we compared cancer patients as a treatment group with liver disease as a control group and low-income group with the highest-income group. The results showed that the extension of NHI benefits coverage led to an increase in the utilization of outpatient services across all income groups, but with a greater increase for the low-income groups, among cancer patients. Moreover, the policy led to a less decrease in the utilization of inpatient services for the low-income group while it decreased across all income groups. Our finding suggests that the extension of NHI benefits coverage improved the income-related equality in health care utilization.

    Because they are easy to administer, rating scales are often used as proxies for utility measures. The authors investigated the relationship between time-tradeoff utilities and rating scale values in two populations: 124 cancer patients asked to evaluate their current states of health and 102 relatives and close friends of cancer patients asked to evaluate health-state scenarios. None of the models tested effectively described the relationship between individual patients' rating scale values and time-tradeoff utilities for their current states of health. In contrast, both a plateau and a power-function model explained the variability in the responses of the relatives reasonably well (R2 = 0.56 and R2 = 0.58, respectively). Given that many respondents who were unwilling to trade off any time assigned rating scale values of well below 100, a plateau model may represent the best approach to adjusting rating scale values for health-state scenarios when it is not feasible to elicit time-tradeoff utilities.

    Background Low back pain (LBP) is common and associated healthcare costs are significant. While clinical practice guidelines have been established in an attempt to reduce costs and healthcare utilization, it is unclear if adherence to physical therapy guidelines for those with LBP is efficacious. Therefore, the purpose of this study was to assess current evidence and evaluate the impact of physical therapy guideline adherence on subsequent healthcare costs and utilization for patients with LBP. Methods An electronic search was conducted in PubMed, CINAHL (EBSCO Host), AMED (Ovid), and PEDro. Studies included in this review were published in peer reviewed journals and the primary mode of treatment was administered by a physical therapist. Also, the definition of adherence was clearly defined based on claims data and at least one measure of cost or utilization reported. Quality assessment was evaluated via a modified Downs and Black checklist. Due to the conceptual heterogeneity in variable measurements, data were qualitatively synthesized and stratified by reported utilization and cost measures. Results A total of 256 results were identified and after omitting duplicates, 4 articles were retained, which were all retrospective in nature. Quality scores ranged between 19 and 21 points out of a possible 26 on the modified Downs and Black checklist. All identified studies used the same definition of guideline adherence, which focused on billing active codes and minimizing use of passive codes. The results demonstrated trends that, with a few exceptions, suggested those patients with LBP that were treated with an adherent guideline program demonstrated decreased healthcare utilization and an overall healthcare savings. Conclusion Preliminary evidence suggests that adherence to established clinical practice guidelines may assist with decreasing healthcare utilization and costs. Additional research based on prospective randomized controlled trials are needed to provide

    2012-01-01

    Background Clinical characteristics and patterns of healthcare utilization in patients with painful neuropathic disorders (PNDs) who are under the care of general practitioners (GPs) in the UK are not well understood. Methods Using a large electronic UK database, we identified all adults (age ≥ 18 years) with any GP encounters between 1 January 2006 - 31 December 2006 at which a diagnosis of PND was noted ("PND patients"). An age-and gender-matched comparison group also was constituted consisting of randomly selected patients with one or more GP encounters-but no mention of PNDs-during this period. Characteristics and patterns of healthcare utilization of patients in the two groups were then examined over the one-year study period. Results The study sample consisted of 31,688 patients with mention of PNDs and an equal number of matched comparators; mean age was 56 years, and 62% were women. The prevalence of various comorbidities was higher among patients in the PND group, including digestive disorders (31% vs. 17% for comparison group), circulatory disorders (29% vs. 22%), and depression (4% vs. 3%) (all p < 0.01). Receipt of prescriptions for pain-related pharmacotherapy also was higher among PND patients, including nonsteroidal anti-inflammatory drugs (56% of PND patients had one or more such prescriptions vs. only 22% in the comparison group), opioids (49% vs. 12%), tricyclic antidepressants (20% vs. 1%), and antiepileptics (12% vs. 1%) (all p < 0.01). PND patients also averaged significantly more GP visits (22.8 vs. 14.2) and referrals to specialists (2.8 vs. 1.4) over one year (both comparisons p < 0.01). Conclusions Patients with PNDs under the care of GPs in the UK have relatively high levels of use of healthcare services and pain-related pharmacotherapy. PMID:22394606

    Background As the number of people with Internet access rises, so does the use of the Internet as a potentially valuable source for health information. Insight into patient use of this information and its correlates over time may reveal changes in the digital divide based on patient age and education. Existing research has focused on patient characteristics that predict Internet information use and research on treatment context is rare. Objective This study aims to (1) present data on the proportion of newly diagnosed breast cancer patients treated in German breast centers from 2007 to 2013 who used the Internet for information on their disease, (2) look into correlations between Internet utilization and sociodemographic characteristics and if these change over time, and (3) determine if use of Internet information varies with the hospitals in which the patients were initially treated. Methods Data about utilization of the Internet for breast cancer–specific health information was obtained in a postal survey of breast cancer patients that is conducted annually in Germany with a steady response rate of 87% of consenting patients. Data from the survey were combined with data obtained by hospital personnel (eg, cancer stage and type of surgery). Data from 27,491 patients from 7 consecutive annual surveys were analyzed for this paper using multilevel regression modeling to account for clustering of patients in specific hospitals. Results Breast cancer patients seeking disease-specific information on the Internet increased significantly from 26.96% (853/3164) in 2007 to 37.21% (1485/3991) in 2013. Similar patterns of demographic correlates were found for all 7 cohorts. Older patients (≥70 years) and patients with <10 years of formal education were less likely to use the Internet for information on topics related to their disease. Internet use was significantly higher among privately insured patients and patients living with a partner. Higher cancer stage and a

    Objectives The objectives of our community-wide investigation were to describe multidecade-long trends (1986-2005) in the utilization of thrombolytic therapy, percutaneous coronary interventions, and coronary artery bypass graft surgery in patients hospitalized with acute myocardial infarction (AMI). Methods The study sample consisted of 9422 greater Worcester (MA) residents hospitalized with confirmed AMI at all metropolitan Worcester medical centers in 11 annual periods between 1986 and 2005. Results Increases in the utilization of percutaneous coronary interventions were observed between 1986 (2.0%) and 2005 (50.7%) with the most rapid increases beginning in the late 1990s. Utilization of coronary artery bypass graft surgery during hospitalization for AMI increased moderately in the 1990s, remained stable thereafter, and declined to being performed in 3.8% of hospitalized patients in 2005. The use of thrombolytic therapy increased between 1986 and 1995 (9.3-25.2%) and decreased markedly thereafter through 2005 (< 1%). Demographic and clinical characteristics of several patients were associated with the receipt of these treatment regimens. Conclusion The results of this study in residents of a large Central New England community suggest an increasingly invasive approach to the management of patients hospitalized with AMI.

    Although researchers have experimentally examined the mechanisms underlying pressure-induced forms of suboptimal performance, or "choking under pressure," there is a lack of research exploring the personal experience of this phenomenon. In an attempt to fill this void in the literature, this study explored experienced golfers' perceptions of the choking experience within a personal construct psychology (Kelly, 1955/1991) framework. Both male and female golfers participated in either a focus group (n = 12; all males) or one-on-one interview (n = 10; female = 7, male = 3) using experience cycle methodology (Oades & Viney, 2000) to describe their perceptions of the choking experience. Discussions were transcribed verbatim and subsequently analyzed using grounded theory analytical techniques (Strauss & Corbin, 1998). Analyses revealed five central categories representing the personal experience of choking under pressure: antecedents, personal investment, choking event, consequences, and learning experiences. The findings reported here suggest that the choking phenomenon, which can involve acute or chronic bouts of suboptimal performance (relative to the performance expectations of the athlete), is a complex process involving the interplay of several cognitive, attentional, emotional, and situational factors. Implications of the findings for a construct definition of choking are discussed, and several applied considerations are offered. PMID:20167952

    Background HIV and TB services are provided free-of-charge in many sub-Saharan African countries, but patients still incur costs. Methods Patient-exit interviews were conducted with a representative sample of 200 HIV-infected patients not yet on ART (pre-ART), 300 ART patients, and 300 TB patients receiving public sector care in rural South Africa. For each group, we calculated health expenditures across different spending categories, time spent traveling to and utilizing services, and how patients financed their spending. Associations between patient group and costs were assessed in multivariate regression models. Results Total monthly health expenditures (1 USD = 7.3 South African Rand, ZAR) were: ZAR 171 (95% CI 134, 207) for pre-ART, ZAR 164 (95% CI 141, 187) for ART, and ZAR 122 (95% CI 105, 140) for TB patients (p=0.01). Total monthly time costs (in hours) were: 3.4 (95% CI 3.3, 3.5) for pre-ART, 5.0 (95% CI 4.7, 5.3) for ART and 3.2 (95% CI 2.9, 3.4) for TB patients (p<0.01). Though overall patient costs were similar across groups, pre-ART patients spent on average ZAR 29.2 more on traditional healers and ZAR 25.9 more on chemists and private doctors than ART patients, while ART patients spent ZAR 34.0 more than pre-ART patients on transport to clinics (p<0.05 for all results). 31% of pre-ART, 39% of ART and 41% of TB patients borrowed money or sold assets to finance health costs. Conclusions Patients receiving nominally free care for HIV/TB face large private costs, commonly leading to financial distress. Subsidized transport, fewer clinic visits, and drug pickup points closer to home could reduce costs for ART patients, potentially improving retention and adherence. Large expenditure on alternative care among pre-ART patients suggests that transitioning patients to ART earlier, as under HIV treatment-as-prevention policies, may not substantially increase patients’ financial burden.

    2016-07-01

    Gatekeeping has been introduced to regulate health care demand and to decrease existing educational inequalities in specialist utilization. This article aims to test whether these policy intentions are met effectively. By pooling two waves of the Survey of Health, Ageing, and Retirement in Europe (SHARE), this study performs a cross-country comparison of the impact of two different types of gatekeeping-obligatory referral and skip-and-pay schemes-on absolute and relative general practitioner and specialist utilization levels as well as their moderating effect on inequalities in health care utilization according to education. Results imply that skip-and-pay gatekeeping schemes are not successful in decreasing specialist use and, moreover, aggravate inequalities in health care use, according to education. These findings question the role of choice in health care and call for instruments other than gatekeeping to make health care more efficient and to buffer existing educational inequalities in health care use.

    Glycated hemoglobin (HbA1c) is an approved and widely used laboratory investigation for diagnosis of diabetes that is not affected by acute changes in blood glucose. Our aim was to analyze the extent to which routine HbA1c measurements diagnose unknown diabetes mellitus (DM) in patients presenting with ST-segment elevation myocardial infarction (STEMI). We also compared outcomes in patients with newly diagnosed DM, previously established DM and those without DM. Consecutive patients undergoing PCI for STEMI from January 2005 to December 2012 were included and routinely performed admission HbA1c was used to identify patients with previously undiagnosed DM (HbA1c ≥6.5 and no history of DM or DM therapy) and pre-DM (HbA1c 5.7% to 6.4%). Overall 1,686 consecutive patients underwent primary percutaneous coronary intervention for STEMI during the study period and follow-up data were available for 1,566 patients (90%). A quarter of the patients (24%, n = 405) had history of DM, 7% (n = 118) had previously undiagnosed DM, and 38.7% (n = 652) had pre-DM. Mortality was comparable in patients with known DM and newly diagnosed DM both in-hospital (11.1% vs 11.9%, p = 0.87) and at 3-year follow-up (27.3% and 24%). Patients with DM, including those who were newly diagnosed, had higher mortality at 3 years (26.5%) compared to those with pre-DM (12.1%) or no dysglycemia (11.2%, p <0.01). In conclusion, a substantial number of patients with STEMI have previously undiagnosed DM (7%). These patients have similar in-hospital and long-term mortality as those with known DM, and outcomes are inferior to patients without dysglycemia. PMID:26768673

    Objective The purpose of this study was to determine the cost-utility of treating anemic dialysis patients with continuous erythropoietin receptor activator (CERA) once monthly or Epoetin Beta (EpoB) thrice weekly compared with a reference strategy of managing anemia with red blood cell transfusion (RBCT). Methods Cost-utility analysis study design. Decision analysis model, National health care payer, over 1 year with the publicly funded health care system. Chronic hemodialysis patients with renal anemia were included. The outcome marker of this study was the incremental cost per quality-adjusted life-year (QALY) gained (incremental cost-utility ratio [ICUR]) of CERA or EpoB relative to RBCT. Results The total cost per patient (in US$) was estimated at $2,176.37, $4,107.01, and $4,356.69 for RBCT, CERA, and EpoB, respectively. The cost-utility ratio was calculated at 4,423.52, 6,955.50, and 7,406.38 $/QALY for RBCT, CERA, and EpoB, with an ICUR of CERA and EpoB in relation to RBCT at 19,606.40 and 22,466.09 $/QALY, respectively. In sensitivity analysis, the model was most sensitive to hospitalization costs, hospital stay, and annual number of RBCT units. Also, assuming utility and survival improvement with erythropoiesis stimulating agents use resulted in a decrease in ICUR at 13,429 $/QALY for CERA and 15,331 $/QALY for EpoB. In probabilistic sensitivity analysis, the main results of our model were unchanged; CERA and EpoB were more costly and more effective than RBCT below a threshold of 19,500 $/QALY. CERA was the best option for a willingness to pay over 19,500 $/QALY. Limitations Some model parameters were obtained from observational data, the comparator RBCT is not the standard of care. Conclusion Our study suggests that managing anemia in dialysis patients with CERA or EpoB may result in better outcomes with higher overall costs. Considering different assumptions, we found substantial variability in the estimates of the cost-utility and incremental of using

    To determine the utility of emergency physician-performed point-of-care biliary ultrasound in the evaluation of emergency department (ED) patients with isolated acute non-traumatic epigastric pain. This was a multi-center prospective observational study of adult patients presenting to the ED with isolated acute non-traumatic epigastric pain. Patients with abdominal tenderness at any site other than the epigastric region, or with a history of gall stones, cholecystectomy, gastrointestinal bleeding, chronic abdominal pain, trauma, or altered mental status were excluded. Emergency physician investigators performed point-of-care biliary ultrasound after clinical assessment. Demographic information, history, physical examination findings, laboratory results, additional diagnostic tests, and disposition data were collected. A total of 51 patients (39 women, 12 men) were enrolled. The mean age of the patients was 36.4 years ± 13.6 (SD). All subjects had isolated epigastric tenderness. Gallstones were found in 20/51 (39%, 95% CI 26-52%) on point-of-care biliary ultrasound. Of the 20 patients who had gallstones, eight had sonographic signs of chloecystitis. The treating emergency physicians' initial evaluation did not plan to include an ultrasound in 17/20 patients with gallstones. 19/20 patients were initially given a GI cocktail by the treating emergency physicians. Point-of-care biliary ultrasound detected gall stones in more than one-third of ED patients with isolated acute non-traumatic epigastric pain. All patients presenting to the ED with non-traumatic epigastric pain should be evaluated for biliary disease with an ultrasound imaging study. Bedside ultrasound can avoid misdiagnosis and expedite management in these patients.

    Background. The aim of this study was to monitor oropharyngeal bacterial colonization in patients indicated for percutaneous endoscopic gastronomy (PEG). Methods. Oropharyngeal swabs were obtained from patients prior to PEG placement. A development of peristomal infection was evaluated. The analysis of oropharyngeal and peristomal site pathogens was done. Results. Consecutive 274 patients referred for PEG due to neurological disorder or cancer completed the study. Oropharyngeal colonization with pathogens was observed in 69% (190/274), dominantly in the neurologic subgroup of patients (P < 0.001). Peristomal infection occurred in 30 (10.9%) of patients and in 57% of them the correlation between oropharyngeal and peristomal agents was present. The presence of oropharyngeal pathogens was assessed as an important risk factor for the development of peristomal infection only in oncological patients (OR = 8.33, 95% CI: 1.66–41.76). Despite a high prevalence of pathogens in neurological patients, it did not influence the risk of peristomal infection with the exception for methicillin resistant Staphylococcus aureus (MRSA) carriers (OR 4.5, 95% CI: 1.08–18.76). Conclusion. During oropharyngeal microbial screening prior to the PEG insertion, the detection of pathogens may be a marker of the increased risk of peristomal infection in cancer patients only. In neurological patients the benefit of the screening is limited to the detection of MRSA carriers. PMID:25243153

    Background Video-assisted thoracoscopic (VATS) lobectomy with a single utility port has emerged as a new technology in recent years. The aim of this study is to review the technology in the treatment of elderly patients with peripheral lung cancer. Methods We retrospectively analyzed the clinical data of 21 elderly patients with peripheral lung cancer who underwent single utility port VATS lobectomy from February 2011 to February 2013 in the First Affiliated Hospital of Soochow University (VATS group). The clinical outcomes and postoperative complications were then compared to data from 32 elderly patients who underwent lobectomy by thoracotomy (TL group). Results No mortality occurred during the postoperative period in either group. There was no statistical difference in surgery duration, the quantity of lymph node dissection or intraoperative blood loss between the VATS and TL groups. However, significant differences existed in the postoperative hospital stay (6.19 ± 1.69 days vs. 8.22 ± 2.55 days), time to first activity out of bed (20.57 ± 7.72 hours vs. 26.81 ± 9.27 hours), chest drainage duration (4.24 ± 1.04 days vs. 5.22 ± 1.29 days), and total postoperative drainage volume (642.86 ± 158.18 mL vs. 787.81 ± 211.55 mL) between the VATS and TL groups (P <0.05). The percentage of patients with no complications in the VATS group (85.71%) is significantly higher when compared with the TL group (56.25%, P <0.05). Conclusion VATS lobectomy with a single utility port is a safe and feasible surgical procedure for selected elderly patients with peripheral lung cancer. PMID:26767004

    This phenomenological study explored the meaning that women with violent partners found in participating in a 20-week group cognitive therapy program called INSIGHT. Through a two-step interview process, ten women who had experienced intimate partner violence described what it meant to them to decide to participate in INSIGHT; what was meaningful about the program; and what influence the program had on their lives. Findings indicated an overarching theme that described a process of Rescuing Self. This study adds support for the utility of interventions, such as INSIGHT, that nurture self-emergence among women who have experienced intimate partner violence. PMID:16849263

    Purpose Hip osteonecrosis frequently complicates treatment with glucocorticoids. When extensive (affecting ≥ 30% of the epiphyseal surface), 80% of joints collapse within 2 years, so interventions are needed to prevent this outcome. Patients and Methods This prospective cohort magnetic resonance imaging (MRI) screening study included all consecutive children treated for acute lymphoblastic leukemia on a single protocol. Hip MRI was performed at 6.5 and 9 months from diagnosis (early screening) and at completion of chemotherapy (final evaluation) to determine whether screening could identify extensive hip osteonecrosis before symptom development. Results Of 498 patients, 462 underwent screening MRI. Extensive asymptomatic osteonecrosis was identified by early screening in 26 patients (41 hips); another four patients (seven hips) were detected after the screening period, such that screening sensitivity was 84.1% and specificity was 99.4%. The number of joints screened to detect one lesion was 20.1 joints for all patients, 4.4 joints for patients older than 10 years, and 198 joints for patients ≤ 10 years old (P < .001). Of the 40 extensive lesions in patients older than 10 years, 19 required total hip arthroplasty and none improved. Of eight extensive lesions in younger patients, none required arthroplasty and four improved. Conclusion In patients age 10 years old or younger who require prolonged glucocorticoid therapy, screening for extensive hip osteonecrosis is unnecessary because their risk is low and lesions tend to heal. In children older than 10 years, early screening successfully identifies extensive asymptomatic lesions in patients who would be eligible for studies of interventions to prevent or delay joint collapse.

    Background Ustekinumab is a fully human monoclonal antibody approved for the treatment of chronic moderate-to-severe plaque psoriasis in adults. However, factors including efficacy, tolerability, ease of use, and cost burden may affect ustekinumab utilization. Noncompliance may, in turn, affect treatment response. Objective To evaluate ustekinumab utilization in the real-world setting in Asia-Pacific countries. Methods In this phase 4 observational study conducted in Indonesia, Malaysia, Singapore, Korea, and Taiwan, adults with plaque psoriasis receiving ustekinumab were followed for up to 52 weeks. Study endpoints were the proportion of all patients using ustekinumab according to label-recommended intervals and the proportion of Korean patients who achieved a psoriasis area severity index 75 response at week 16. Safety was assessed by monitoring adverse events. Results Overall, 169 patients received ustekinumab (Korea, n=102; other countries, n=67). Just over half (56.2%) of patients used ustekinumab with the label-recommended interval from baseline to week 40; the proportion was higher in Korea (73.5%) than in other countries (29.9%), probably because ustekinumab was provided without charge for Korean patients up to week 40. Noncompliance increased after week 40 in Korea and from week 28 in other Asia-Pacific countries, with cost cited as the most common reason. At week 16, 56.9% of Korean patients achieved a Psoriasis Area Severity Index 75 response. Safety results were in line with those seen in previous studies. Conclusion More than half of all patients in Asia-Pacific countries used ustekinumab as per the label-recommended dose interval, but reimbursement variations between countries may have confounded overall results.

    Background: Chemotherapy for lymph nodes cancer is often composed of several drugs that are used in a treatment program. Objectives: The aim of this study was to perform a cost-utility analysis of IEV regimen (ifosfamide, epirubicin and etoposide) versus ESHAP regimen (etoposide, methylprednisolone, high-dose cytarabine, and cisplatin) in patients with lymphoma in the south of Iran. Patients and Methods: This was a cost-utility analysis done as a cross-sectional study in the south of Iran. Using decision tree, expected costs, quality -adjusted life years (QALYs) and the incremental cost-effectiveness ratio (ICER) were estimated. In addition, the robustness of results was examined by sensitivity analysis. Results: The results of this study indicated that the total lymphoma patients were about 65 people that 27 patients received IEV regimen and 38 patients ESHAP (43 patients with Hodgkin’s and 22 with non-Hodgkin lymphoma). The results of decision tree showed that in the IEV arm, the expected cost was $20952.93 and the expected QALYs was 3.89 and in the ESHAP arm, the expected cost was $31691.74 and the expected QALYs was 3.86. Based on the results of the study, IEV regimen was cost-effective alternative to the ESHAP regimen. Conclusions: According to the results of this study, it is recommended that oncologists use IEV instead of ESHAP in the treatment of patients with lymphoma and because of high costs of IEV drug costs, it is suggested that IEV drugs should be covered by insurance.

    Aim This paper is a report of a study to identify critical thinking learning needs of new and experienced nurses. Background Concern for patient safety has grown worldwide as high rates of error and injury continue to be reported. In order to improve patient safety, nurses must be able to recognize changes in patient condition, perform independent nursing interventions, anticipate orders and prioritize. Methods In 2004–2006, a consecutive sample of 2144 newly hired nurses in a university-affiliated healthcare system completed the Performance Based Development System Assessment consisting of 10 videotaped vignettes depicting change in patient status. Results were reported as meeting or not meeting expectations. For nurses not meeting expectations, learning needs were identified in one of six sub-categories. Results Overall, 74.9% met assessment expectations. Learning needs identified for nurses not meeting expectations included initiating independent nursing interventions (97.2%), differentiation of urgency (67%), reporting essential clinical data (65.4%), anticipating relevant medical orders (62.8%), providing relevant rationale to support decisions (62.6%) and problem recognition (57.1%). Controlling for level of preparation, associate (P = 0.007) and baccalaureate (P < 0.0001) nurses were more likely to meet expectations as years of experience increased; a similar trend was not seen for diploma nurses (P = 0.10). Controlling for years of experience, new graduates were less likely to meet expectations compared with nurses with ≥10 years experience (P = 0.046). Conclusion Patient safety may be compromised if a nurse cannot provide clinically competent care. Assessments such as the Performance Based Development System can provide information about learning needs and facilitate individualized orientation targeted to increase performance level.

    2015-01-01

    Background and Purpose Although the modified Rankin Scale (mRS) is the most commonly employed primary endpoint in acute stroke trials, its power is limited when analyzed in dichotomized fashion and its indication of effect size challenging to interpret when analyzed ordinally. Weighting the seven Rankin levels by utilities may improve scale interpretability while preserving statistical power. Methods A utility weighted mRS (UW-mRS) was derived by averaging values from time-tradeoff (patient centered) and person-tradeoff (clinician centered) studies. The UW-mRS, standard ordinal mRS, and dichotomized mRS were applied to 11 trials or meta-analyses of acute stroke treatments, including lytic, endovascular reperfusion, blood pressure moderation, and hemicraniectomy interventions. Results Utility values were: mRS 0–1.0; mRS 1 - 0.91; mRS 2 - 0.76; mRS 3 - 0.65; mRS 4 - 0.33; mRS 5 & 6 - 0. For trials with unidirectional treatment effects, the UW-mRS paralleled the ordinal mRS and outperformed dichotomous mRS analyses. Both the UW-mRS and the ordinal mRS were statistically significant in six of eight unidirectional effect trials, while dichotomous analyses were statistically significant in two to four of eight. In bidirectional effect trials, both the UW-mRS and ordinal tests captured the divergent treatment effects by showing neutral results whereas some dichotomized analyses showed positive results. Mean utility differences in trials with statistically significant positive results ranged from 0.026 to 0.249. Conclusion A utility-weighted mRS performs similarly to the standard ordinal mRS in detecting treatment effects in actual stroke trials and ensures the quantitative outcome is a valid reflection of patient-centered benefits.

    At many institutions, it is common practice for trauma patients with traumatic intracranial hemorrhage (ICH) to receive routine repeat head computed tomographic (CT) scans after the initial CT scan, regardless of symptoms, to evaluate progression of the injury. The purpose of this study was to assess quantifiable risk factors (age, anticoagulation, gender) that could place patients at greater risk for progression of injury, thus requiring surgical intervention (craniotomy, craniectomy) for which serial CT scanning would be useful. From January 2014 to June 2015, a total of 211 patients presented with traumatic ICH and 198 were eligible for inclusion. Twenty-six patients required operative intervention for ICH. One of 26 patients went to the operating room as a result of repeat head CT scans without associated mental status change, change in neurological examination, or associated symptoms such as nausea or vomiting. Significant changes in patient management due to routine repeat CT scans were not observed. There were no statistically significant risk factors identified to place patients at higher risk for progression of disease. The data from this analysis emphasized the importance of nursing care in identifying and relaying changes in patient condition to the trauma team. PMID:27618379

    Multiple sclerosis (MS) is a demyelinating disease in the central nervous system. Genetics have been considered as a leading factor in the prevalence and disease course of MS. We have presented an informatics-based eFolder system for integrating patients' clinical data with MR images and lesion quantification results. The completed eFolder system has been designed and developed in aiding to evaluate disease manifestation differences in Hispanic and Caucasian MS patients. MS lesion data, as shown in MRI, can be extracted by the 3-D automatic lesion detection tool in the eFolder, and data storing and mining tools in eFolder is able to extract and compare data from individual patients. The computer-aided detection (CAD) algorithm has been modified and enhanced to include spatial information as detection criteria. For this study, 36 Caucasian MS patients and 36 matched Hispanic patients have been selected. Most recent MR images of the patients are collected, and images are evaluated both by the CAD tool in the eFolder and radiologists. The results are compared between Caucasian and Hispanic patients and statistically evaluated to see if the two populations have significant difference in lesion presentations. The results can be used to evaluate differences in the two groups of patients and to evaluate the new CAD algorithm's performance with radiologists' contours. Significant findings can further evaluate effectiveness of MS eFolder in MS-related research.

    AIM: To study clinical and histopathological features of nonalcoholic fatty liver disease (NAFLD) in patients with and without type 2 diabetes mellitus (T2DM) using updated nonalcoholic steatohepatitis clinical research network (NASH-CRN) grading system. METHODS: We retrospectively analyzed data of 235 patients with biopsy proven NAFLD with and without T2DM. This database was utilized in the previously published study comparing ethnicity outcomes in NAFLD by the same corresponding author. The pathology database from University of Chicago was utilized for enrolling consecutive patients who met the criteria for NAFLD and their detailed clinical and histopathology findings were obtained for comparison. The relevant clinical profile of patients was collected from the Electronic Medical Records around the time of liver biopsy and the histology was read by a single well-trained histopathologist. The updated criteria for type 2 diabetes have been utilized for analysis. Background data of patients with NASH and NAFLD has been included. The mean differences were compared using χ2 and t-test along with regression analysis to evaluate the predictors of NASH and advanced fibrosis. RESULTS: Patients with NAFLD and T2DM were significantly older (49.9 vs 43.0, P < 0.01), predominantly female (71.4 vs 56.3, P < 0.02), had higher rate of metabolic syndrome (88.7 vs 36.4, P < 0.01), had significantly higher aspartate transaminase (AST)/alanine transaminase (ALT) ratio (0.94 vs 0.78, P < 0.01) and Fib-4 index (1.65 vs 1.06, P < 0.01) as markers of NASH, showed higher mean NAFLD activity score (3.5 vs 3.0, P = 0.03) and higher mean fibrosis score (1.2 vs 0.52, P < 0.01) compared to patients with NAFLD without T2DM. Furthermore, advanced fibrosis (32.5 vs 12.0, P < 0.01) and ballooning (27.3 vs 13.3, P < 0.01) was significantly higher among patients with NAFLD and T2DM compared to patients with NAFLD without T2DM. On multivariate analysis, T2DM was independently associated with NASH

    Subaortic obstruction is an important determinant of the clinical presentation of and therapeutic approach to patients with hypertrophic cardiomyopathy. Therefore, assessment of the presence and magnitude of the intraventricular pressure gradient is paramount in the clinical evaluation of these patients. To establish the utility of continuous wave Doppler echocardiography in assessing the pressure gradient in hypertrophic cardiomyopathy, 28 patients representing the wide hemodynamic spectrum of this disease underwent simultaneous determination of the subaortic gradient by continuous wave Doppler ultrasound and cardiac catheterization. With use of the modified Bernoulli equation, the Doppler-estimated gradient showed a strong correlation with the maximal instantaneous pressure difference measured at catheterization, both under basal conditions (r = 0.93; p less than 0.0001) and during provocative maneuvers (r = 0.89; p less than 0.0001). In 26 of the 28 patients, all assessments of the subaortic gradient were in agreement within 15 mm Hg (average difference 5 +/- 3 mm Hg). In the other two patients there were substantial differences between these measurements (under basal conditions in one patient and after provocation in another), although the Doppler technique predicted the presence of marked subaortic obstruction in each. In both patients the erroneous interpretation was due to superimposition of the mitral regurgitation signal on that of left ventricular outflow. Doppler waveforms from the left ventricular outflow tract showed variability in contour among different patients and in individual patients. Hence, continuous wave Doppler echocardiography is a useful noninvasive method for estimating the subaortic gradient in patients with hypertrophic cardiomyopathy. However, technical factors such as contamination of the outflow tract jet with that of mitral regurgitation and variability in waveform configuration may importantly influence such assessments of the

    Background Patients with schizophrenia have difficulty managing their medical healthcare needs, possibly resulting in delayed treatment and poor outcomes. We analyzed whether patients reduced primary care use over time, differentially by diagnosis with schizophrenia, diabetes, or both schizophrenia and diabetes. We also assessed whether such patterns of primary care use were a significant predictor of mortality over a 4-year period. Methods The Veterans Healthcare Administration (VA) is the largest integrated healthcare system in the United States. Administrative extracts of the VA's all-electronic medical records were studied. Patients over age 50 and diagnosed with schizophrenia in 2002 were age-matched 1:4 to diabetes patients. All patients were followed through 2005. Cluster analysis explored trajectories of primary care use. Proportional hazards regression modelled the impact of these primary care utilization trajectories on survival, controlling for demographic and clinical covariates. Results Patients comprised three diagnostic groups: diabetes only (n = 188,332), schizophrenia only (n = 40,109), and schizophrenia with diabetes (Scz-DM, n = 13,025). Cluster analysis revealed four distinct trajectories of primary care use: consistent over time, increasing over time, high and decreasing, low and decreasing. Patients with schizophrenia only were likely to have low-decreasing use (73% schizophrenia-only vs 54% Scz-DM vs 52% diabetes). Increasing use was least common among schizophrenia patients (4% vs 8% Scz-DM vs 7% diabetes) and was associated with improved survival. Low-decreasing primary care, compared to consistent use, was associated with shorter survival controlling for demographics and case-mix. The observational study was limited by reliance on administrative data. Conclusion Regular primary care and high levels of primary care were associated with better survival for patients with chronic illness, whether psychiatric or medical. For schizophrenia

    Background Maintenance of a well-functioning vascular access and minimal needling pain are important goals for achieving adequate dialysis and improving the quality of life in hemodialysis (HD) patients. Far-infrared (FIR) therapy may improve endothelial function and increase access blood flow (Qa) and patency in HD patients. The aim of this study was to evaluate effects of FIR therapy on Qa and patency, and needling pain in HD patients. Methods This prospective clinical trial enrolled 25 outpatients who maintained HD with arteriovenous fistula. The other 25 patients were matched as control with age, sex, and diabetes. FIR therapy was administered for 40 minutes during HD 3 times/wk and continued for 12 months. The Qa was measured by the ultrasound dilution method, whereas pain was measured by a numeric rating scale at baseline, then once per month. Results One patient was transferred to another facility, and 7 patients stopped FIR therapy because of an increased body temperature and discomfort. FIR therapy improved the needling pain score from 4 to 2 after 1 year. FIR therapy increased the Qa by 3 months and maintained this change until 1 year, whereas control patients showed the decrease in Qa. The 1-year unassisted patency with FIR therapy was not significantly different from control. Conclusion FIR therapy improved needling pain. Although FIR therapy improved Qa, the unassisted patency was not different compared with the control. A larger and multicenter study is needed to evaluate the effect of FIR therapy. PMID:27069856

    2011-01-01

    Background In order to estimate the future demands for health services, the analysis of current utilization patterns of the elderly is crucial. The aim of this study is to analyze ambulatory medical care utilization by elderly patients in relation to age, gender, number of chronic conditions, patterns of multimorbidity, and nursing dependency in Germany. Methods Claims data of the year 2004 from 123,224 patients aged 65 years and over which are members of one nationwide operating statutory insurance company in Germany were studied. Multimorbidity was defined as the presence of 3 or more chronic conditions of a list of 46 most prevalent chronic conditions based on ICD 10 diagnoses. Utilization was analyzed by the number of contacts with practices of physicians working in the ambulatory medical care sector and by the number of different physicians contacted for every single chronic condition and their most frequent triadic combinations. Main statistical analyses were multidimensional frequency counts with standard deviations and confidence intervals, and multivariable linear regression analyses. Results Multimorbid patients had more than twice as many contacts per year with physicians than those without multimorbidity (36 vs. 16). These contact frequencies were associated with visits to 5.7 different physicians per year in case of multimorbidity vs. 3.5 when multimorbidity was not present. The number of contacts and of physicians contacted increased steadily with the number of chronic conditions. The number of contacts varied between 35 and 54 per year and the number of contacted physicians varied between 5 to 7, depending on the presence of individual chronic diseases and/or their triadic combinations. The influence of gender or age on utilization was small and clinically almost irrelevant. The most important factor influencing physician contact was the presence of nursing dependency due to disability. Conclusion In absolute terms, we found a very high rate of

    Background Studies demonstrate an increase in radiation exposure with transradial approach (TRA) when compared with transfemoral approach (TFA) for coronary angiography. Given the learning curve associated with TRA, it is not known if this increased radiation exposure to patients is seen when procedures are performed by experienced operators. Methods We retrospectively evaluated 1,696 patients who underwent coronary angiography with or without percutaneous coronary intervention (PCI) by experienced operators at a tertiary center from October 2010 to June 2011. Experienced operators were defined as those that perform >75 PCIs/year with >95% of cases performed using the TRA or TFA approach for ≥5 years. The outcomes of interest were dose area product (DAP) and fluoroscopy time (FT). Results Of the 1,696 patients, 1,382 (81.5%) were performed by experienced femoral operators using TFA and 314 (18.5%) were performed by experienced radial operators using TRA. Most of these cases (65.4%) were diagnostic only (870 TFA and 240 TRA) with both DAP (6040 [3210–8786] vs 5019 [3377–6869] μGy·m2, P = .003] and FT [6.2 [4.0–10.3] vs 3.3 [2.6–5.0] minutes, P < .001) significantly higher using TRA versus TFA. For procedures involving PCI, despite similar baseline patient, procedural and lesion characteristics, DAP and FT remained significantly higher using TRA versus TFA (19,649 [11,996–25,929] vs 15,395 [10,078–21,617] μGy·m2, P = .02 and 22.1 [13.3–31.0] vs. 13.8 [9.8–20.3] minutes, P < .001). Conclusions In a contemporary cohort of patients undergoing coronary angiography by experienced operators, TRA was associated with higher radiation exposure when compared with TFA. PMID:23453094

    The lifetime utility of liver transplantation (LT) in patients with hepatocellular carcinoma (HCC) is still controversial. The aim of this study was to ascertain when LT is cost-effective for HCC patients, with a view to proposing new transplant selection criteria. The study involved a real cohort of potentially transplantable Italian HCC patients (n = 2419 selected from the Italian Liver Cancer group database) who received nontransplant therapies. A non-LT survival analysis was conducted, the direct costs of therapies were calculated, and a Markov model was used to compute the cost utility of LT over non-LT therapies in Italian and US cost scenarios. Post-LT survival was calculated using the alpha-fetoprotein (AFP) model on the basis of AFP values and radiological size and number of nodules. The primary endpoint was the net health benefit (NHB), defined as LT survival benefit in quality-adjusted life years minus incremental costs (US $)/willingness to pay. The calculated median cost of non-LT therapies per patient was US $53,042 in Italy and US $62,827 in the United States. On Monte Carlo simulation, the NHB of LT was always positive for AFP model values ≤ 3 and always negative for values > 7 in both countries. A multivariate model showed that nontumor variables (patient's age, Child-Turcotte-Pugh [CTP] class, and alternative therapies) had the potential to shift the AFP model threshold of LT cost-ineffectiveness from 3 to 7. LT proved always cost-effective for HCC patients with AFP model values ≤ 3, whereas the cost-ineffectiveness threshold ranged between 3 and 7 using nontumor variables. PMID:26183802

    We examined the benefit of tissue plasminogen activator (tPA), delivered as part of usual stroke management, on patient-reported outcomes and health care utilization. Using a case control design, patients who received tPA as part of usual stroke management were compared with patients who would have received tPA had they arrived to the hospital within the therapeutic time window. Data were collected from surveys 6 months after stroke using standardized patient-reported outcome measures and questions about health care utilization. Demographic and medical data were acquired from hospital records. Patients were matched on stroke severity, age, race, and gender. Matching was done with 1:2 ratio of tPA to controls. Results were compared between groups with 1-tailed tests because of a directionally specific hypothesis in favor of the tPA group. The tPA (n = 78) and control (n = 156) groups were matched across variables, except for stroke severity, which was better in the control group; subsequent analyses controlled for this mismatch. The tPA group reported better physical function, communication, cognitive ability, depressive symptomatology, and quality of life/participation compared with the control group. Fewer people in the tPA group reported skilled nursing facility stays, emergency department visits, and rehospitalizations after their stroke compared with controls. Reports of other postacute services were not different between groups. Although it is known that tPA reduces disability, this is the first study to demonstrate the effectiveness of tPA in improving meaningful, patient-reported outcomes. Thus, use of tPA provides a large benefit to the daily lives of people with ischemic stroke.

    Early identification and prognostic stratification of delayed graft function following renal transplantation has significant potential to improve outcome. Mass spectrometry analysis of serum samples, before and on day 2 post transplant from five patients with delayed graft function and five with an uncomplicated transplant, identified aminoacylase-1 (ACY-1) as a potential outcome biomarker. Following assay development, analysis of longitudinal samples from an initial validation cohort of 55 patients confirmed that the ACY-1 level on day 1 or 2 was a moderate predictor of delayed graft function, similar to serum creatinine, complementing the strongest predictor cystatin C. A further validation cohort of 194 patients confirmed this association with area under ROC curves (95% CI) for day 1 serum (138 patients) of 0.74 (0.67-0.85) for ACY-1, 0.9 (0.84-0.95) for cystatin C, and 0.93 (0.88-0.97) for both combined. Significant differences in serum ACY-1 levels were apparent between delayed, slow, and immediate graft function. Analysis of long-term follow-up for 54 patients with delayed graft function showed a highly significant association between day 1 or 3 serum ACY-1 and dialysis-free survival, mainly associated with the donor-brain-dead transplant type. Thus, proteomic analysis provides novel insights into the potential clinical utility of serum ACY-1 levels immediately post transplantation, enabling subdivision of patients with delayed graft function in terms of long-term outcome. Our study requires independent confirmation.

    Abstract Rationale, aims and objectives Clinical trial data suggest that patients who have received bisphosphonates continue to benefit from them after discontinuation. However, data from real‐world clinical practice are inconclusive. We assessed the impact of persistence and discontinuation on health resource utilization (HRU) and fracture rate in women who were prescribed oral bisphosphonates. Method The study used data from the UK Clinical Practice Research Datalink. Women aged 50 years or older with a first prescription of oral bisphosphonate therapy between January 2000 and December 2007 were included. Multivariate modelling compared rate ratios for fracture and HRU between patients who had discontinued medication (shorter persistence group) and patients who took their medication for longer (longer persistence group). The interactions of elapsed time (measured as 6‐month intervals) with HRU and with fracture rate for all patients within paired groups were also assessed. Results Overall, 36 320 patients were included. Pairwise comparisons showed that HRU and fracture rates were lower in longer persistence groups than in shorter persistence groups. Analysis by 6‐month interval showed that, across all patients in persistence group pairs, HRU significantly increased for each additional 6 months elapsed; trends towards increased risk of fracture were also seen. Conclusion In contrast to results from clinical trials, in this patient population the protective effect of oral bisphosphonates after discontinuation was not sufficient to reduce HRU and fracture rates to the levels that would be seen if patients had continued on therapy. Reducing the rate of treatment discontinuation may decrease the burden that osteoporosis places on both patients and health care systems. PMID:26279458

    Normalization of the serum free light chain ratio (FLCr) with the absence of bone marrow monoclonal plasma cells following achievement of a complete response (CR) to therapy denotes a stringent CR in multiple myeloma (MM), and is associated with improved overall survival (OS). However, its value in patients achieving patients achieving a normalization of FLCr with initial therapy of MM will have an improved outcome, even in the absence of a CR. We retrospectively evaluated 449 patients with newly-diagnosed MM with measurable disease at baseline, who did not achieve a CR with initial therapy. One hundred fifty three patients (34%) had a normal FLCr while 296 (66%) had an abnormal ratio. Patients with a normal FLCr had a longer progression-free survival (PFS) (29 vs. 16 months, P <.001) and OS (91 vs. 58 months, P <.001). Normalization of FLCr retained its prognostic value in a multivariable model. Our results suggest an important role for sFLC measurement in disease monitoring even in patients who achieve only a partial response to therapy. Obtaining a normal FLCr confers a favorable prognosis independent from other factors, supporting the inclusion of sFLC in all levels of response criteria. PMID:25962523

    Evidence based on average patient data, which occupies most of our present day information databases, does not fulfil the needs of individual patient-centred health care. In spite of the unprecedented expansion in medical information we still do not have the types of information required to allow us to tailor optimal care for a given individual patient. As our current information is chiefly provided in disconnected silos, we need an information system that can seamlessly integrate different types of information to meet diverse user group needs. Groups of certain individual medical learners namely patients, medical students and health professionals share the patient's need to increasingly interact with and seek knowledge and solutions offered by others (individual medical learners) who have the lived experiences that they would benefit to access and learn from. A web-based user-driven learning solution may be a stepping-stone to address the present problem of information oversupply in medicine that mostly remains underutilized, as it doesn't meet the needs of the individual patient and health professional user. The key to its success would be to relax central control and make local trust and strategic health workers feel more engaged in the project such that it is truly user-driven.

    The aim of this study was to investigate the role of 2-fluorine-18-fluoro-2-deoxy-D-glucose ((18)F-FDG) positron emission tomography/computed tomography (PET/CT) in the initial staging and prediction of bone marrow involvement in patients with newly diagnosed lymphoma. A total of 185 patients with newly diagnosed lymphoma were enrolled. All patients received PET/CT and bone marrow biopsy as part of a staging work-up. At the initial staging, 17 patients (9.2%) with occult nodal or extranodal lesions were upstaged after a review of the PET/CT studies. PET/CT was found to be useful in the differentiation of aggressive lymphoma subtypes from the indolent subtype based on higher standardized uptake value (SUV) (16.67 vs. 7.98, p < 0.001). The results of bone marrow biopsy and PET/CT in the detection of bone marrow involvement were concordant in 152 patients (82.1%); positive concordance was observed in 21 patients, and negative concordance was observed in 131 patients. A high concordance rate was found between aggressive B cell lymphoma and Hodgkin's lymphoma (88.1% and 93.8%, respectively). High negative predictive values (NPVs) for excluding bone marrow involvement were observed in aggressive B-cell lymphoma (93.2%) and Hodgkin's lymphoma (100%). Diffuse bone marrow FDG uptake accurately predicted bone marrow in aggressive B-cell lymphoma with a positive predictive value (PPV) of 100%. The concordance rate was lower in indolent B-cell lymphoma (66.0%). In conclusion, PET/CT resulted in the upstaging of patients with occult extranodal or nodal lesions. A high SUV level can predict aggressive subtype of lymphoma and detect aggressive components in indolent lymphoma. PET/CT had a high PPV for aggressive B-cell lymphoma with diffuse bone marrow FDG uptake and high NPVs for excluding bone marrow involvement in aggressive B-cell lymphoma and Hodgkin's lymphoma.

    Purpose To assess trends in the use of ancillary diagnostic tests in the evaluation of patients with open-angle glaucoma (OAG) and glaucoma suspects over the past decade. Design Retrospective longitudinal cohort analysis. Participants 169,917 individuals with OAG and 395,721 with suspected glaucoma age ≥40 enrolled in a national United States managed care network between 2001–2009. Methods Claims data were analyzed to assess trends in visual field (VF) testing, fundus photography (FP), and other ocular imaging (OOI) testing for patients with OAG or suspected glaucoma in 2001–2009. Repeated measures logistic regression was performed to identify differences in the odds of undergoing these procedures in 2001, 2005, and 2009 and whether differences exist for patients under the exclusive care of optometrists versus ophthalmologists. Main Outcome Measures Odds and annual probabilities of undergoing VF testing, FP, and OOI for OAG from 2001–2009. Results For patients with OAG, the odds of undergoing VF testing decreased by 36% from 2001 to 2005, 12% from 2005 to 2009, and 44% from 2001 to 2009. By comparison, the odds of having OOI increased by 100% from 2001 to 2005, 24% from 2005 to 2009, and 147% from 2001 to 2009. Probabilities of undergoing FP were relatively low (13–25%) for both provider types and remained fairly steady over the decade. For patients cared for exclusively by optometrists, the probability of VF testing decreased from 66% in 2001 to 44% in 2009. Among those seen exclusively by ophthalmologists, the probability of VF testing decreased from 65% in 2001 to 51% in 2009. The probability of undergoing OOI increased from 26% in 2001 to 47% in 2009 for patients of optometrists and from 30% in 2001 to 46% in 2009 for patients of ophthalmologists. By 2008, patients with OAG receiving care exclusively by optometrists had a higher probability of undergoing OOI than VF testing. Conclusion During 2001–2009 OOI rose dramatically whereas VF testing

    A retrospective chart review was performed at 3 Swedish hospitals to evaluate the utilization, outcomes, and cost of using epoetin alfa or darbepoetin alfa to treat cancer patients with chemotherapy-related anemia. Data on dosage, duration of treatment, hematologic response, red blood cell transfusions, and healthcare resource consumption were collected and analyzed at various time points following the initiation of drug therapy. A significantly faster hematologic response and increase in hemoglobin were observed in patients treated with epoetin alfa. Dosages used in clinical practice appeared to be lower than those recommended by Swedish treatment guidelines. There were no significant differences in resource utilization or healthcare costs between the 2 treatment groups. By day 112, the mean treatment cost per patient, in Swedish kronors (SEK), was SEK74,701 (approximately US$9800 or approximately 8300) with epoetin alfa and SEK85,285 (approximately US$11,000 or approximately 9500) with darbepoetin alfa. Drug acquisition and administration accounted for 81% and 67% of the total cost of epoetin alfa and darbepoetin alfa therapy, respectively; the remainder of the total cost was for hospitalization and transfusions.

    Background Serum procalcitonin levels have been used as a biomarker of invasive bacterial infection and recently have been advocated to guide antibiotic therapy in patients with chronic obstructive pulmonary disease (COPD). However, rigorous studies correlating procalcitonin levels with microbiologic data are lacking. Acute exacerbations of COPD (AECOPD) have been linked to viral and bacterial infection as well as noninfectious causes. Therefore, we evaluated procalcitonin as a predictor of viral versus bacterial infection in patients hospitalized with AECOPD with and without evidence of pneumonia. Methods Adults hospitalized during the winter with symptoms consistent with AECOPD underwent extensive testing for viral, bacterial, and atypical pathogens. Serum procalcitonin levels were measured on day 1 (admission), day 2, and at one month. Clinical and laboratory features of subjects with viral and bacterial diagnoses were compared. Results In total, 224 subjects with COPD were admitted for 240 respiratory illnesses. Of these, 56 had pneumonia and 184 had AECOPD alone. A microbiologic diagnosis was made in 76 (56%) of 134 illnesses with reliable bacteriology (26 viral infection, 29 bacterial infection, and 21 mixed viral bacterial infection). Mean procalcitonin levels were significantly higher in patients with pneumonia compared with AECOPD. However, discrimination between viral and bacterial infection using a 0.25 ng/mL threshold for bacterial infection in patients with AECOPD was poor. Conclusion Procalcitonin is useful in COPD patients for alerting clinicians to invasive bacterial infections such as pneumonia but it does not distinguish bacterial from viral and noninfectious causes of AECOPD.

    2011-01-01

    The Pain Research Group of the world health organization (WHO) Collaborating Centre for Symptom Evaluation in Cancer Care had developed the Brief Pain Inventory (BPI), a pain assessment tool for use with cancer patients. The BPI measures both the intensity of pain (sensory dimension) and interference of pain in the patient's life (reactive dimension). The objective of this review paper was to provide a detailed update of existing evidence on applicability of BPI in evaluation of patients with cancer pain. The BPI demonstrated good construct and concurrent validity. It was translated and validated into many languages – Brazilian, Chinese, Greek, Hindi, Italian, Japanese, Korean, Malay, Norwegian, Polish, Russian, Spanish, Taiwanese and Thai. The BPI was validated in patient populations such as bone metastases, breast cancer and postoperative cancer patients. The BPI can be used both as a quantitative or a qualitative measure for statistical analysis. The BPI was a powerful tool and, having demonstrated both reliability and validity across cultures and languages, was being adopted in many countries for clinical pain assessment, epidemiological studies, and in studies on the effectiveness of pain treatment. Future studies are warranted on its responsiveness and cross-cultural adaptation into other cancer pain syndromes and into other Indian languages. PMID:21976850

    Sequencing of the mutant allele fraction of circulating cell-free DNA (cfDNA) derived from tumors is increasingly utilized to detect actionable genomic alterations in cancer. We conducted a prospective blinded study of a comprehensive cfDNA sequencing panel with 54 cancer genes. To evaluate the concordance between cfDNA and tumor DNA (tDNA), sequencing results were compared between cfDNA from plasma and genomic tumor DNA (tDNA). Utilizing next generation digital sequencing technology (DST), we profiled approximately 78,000 bases encoding 512 complete exons in the targeted genes in cfDNA from plasma. Seventy-five patients were prospectively enrolled between February 2013 and March 2014, including 61 metastatic cancer patients and 14 clinical stage II CRC patients with matched plasma and tissue samples. Using the 54-gene panel, we detected at least one somatic mutation in 44 of 61 tDNA (72.1%) and 29 of 44 (65.9%) cfDNA. The overall concordance rate of cfDNA to tDNA was 85.9%, when all detected mutations were considered. We collected serial cfDNAs during cetuximab-based treatment in 2 metastatic KRAS wild-type CRC patients, one with acquired resistance and one with primary resistance. We demonstrate newly emerged KRAS mutation in cfDNA 1.5 months before radiologic progression. Another patient had a newly emerged PIK3CA H1047R mutation on cfDNA analysis at progression during cetuximab/irinotecan chemotherapy with gradual increase in allele frequency from 0.8 to 2.1%. This blinded, prospective study of a cfDNA sequencing showed high concordance to tDNA suggesting that the DST approach may be used as a non-invasive biopsy-free alternative to conventional sequencing using tumor biopsy.

    Background With the advent of the direct-acting antiviral agents (DAAs), significant drug-drug interaction (DDI) potential now exists for patients treated for chronic hepatitis C virus (HCV) infection. However, little is known about how often patients with HCV use medications that may interact with newer HCV treatments, especially those with CYP3A DDI potential. Methods Using a large United States commercial insurance database, medication use and comorbidity burden was examined among adult patients with a chronic HCV diagnosis from 2006-2010. Medications were examined by total number of prescription claims, proportion of patients exposed, and DDI potential with prototypical CYP3A DAAs, boceprevir and telaprevir, for which data were available. Results Patient comorbidity burden was high and increased over the study period. Medication use was investigated in 53,461 patients with chronic HCV. Twenty-one (53%) of the top 40 most utilized medications were classified as having interaction potential, with 62% of patients received at least one of the top 22 interacting medications by exposure. Of these, 59% and 41% were listed in a common DDI resource but not in medication prescribing information, 77% and 77% had not been investigated in DDI studies, 32% and 27% did not have clear recommendations for DDI management, and only 14% and 23% carried a recommendation to avoid coadministration for boceprevir and telaprevir, respectively. Conclusion Practitioners may expect a medication with CYP3A DDI potential in two-thirds of patients with HCV and almost one-half of the most frequently used medications. However, DDI potential may not be reflected in prescribing information. PMID:25014625

    Traditionally, the effects of physical training in patients with chronic heart failure (CHF) are evaluated by changes in peak oxygen uptake (peak VO(2)). The assessment of peak VO(2), however, is highly dependent on the patients' motivation. The aim of the present study was to evaluate the clinical utility of effort-independent exercise variables for detecting training effects in CHF patients. In a prospective controlled trial, patients with stable CHF were allocated to an intervention group (N = 30), performing a 12-week combined cycle interval and muscle resistance training program, or a control group (N = 18) that was matched for age, gender, body composition and left ventricular ejection fraction. The following effort-independent exercise variables were evaluated: the ventilatory anaerobic threshold (VAT), oxygen uptake efficiency slope (OUES), the V(E)/VCO(2) slope and the time constant of VO(2) kinetics during recovery from submaximal constant-load exercise (tau-rec). In addition to post-training increases in peak VO(2) and peak V(E), the intervention group showed significant within and between-group improvements in VAT, OUES and tau-rec. There were no significant differences between relative improvements of the effort-independent exercise variables in the intervention group. In contrast with VAT, which could not be determined in 9% of the patients, OUES and tau-rec were determined successfully in all patients. Therefore, we conclude that OUES and tau-rec are useful in clinical practice for the assessment of training effects in CHF patients, especially in cases of poor subject effort during symptom-limited exercise testing or when patients are unable to reach a maximal exercise level.

    Patients with chronic gout refractory to conventional urate-lowering therapy have high rates of flares and incidence of tophi, which impose a significant disease and potentially economic burden. This study examined healthcare resource use and costs stratified by disease burden. Adult patients diagnosed with gout (ICD-9-CM:274.xx) and having had ≥3 flares defined by clinical surrogates within a 12-month period were selected for the case cohort from the Thomson MarketScan databases (2003/Q3-2008/Q3). Only patients who had received allopurinol treatment and a diagnosis of tophi (ICD-9-CM:274.8x) at any time before the first flare (index date) or within 12 months postindex were included and were matched in a 1:1 ratio with control gout-free subjects. The comorbidity burden, healthcare resource use, and annual healthcare costs (2008 US$) in the 12-month postindex period were compared between both cohorts using regression models adjusted for demographic characteristic and stratified for patients with ≥6 flares. A total of 679 gout patients met the inclusion criteria for the study and had a higher prevalence of comorbidities than their matched controls. Gout cohort had a significantly higher incidence of emergency room, hospitalizations, outpatient visits, and other medical services than did their matched controls (all comparisons, uncorrected P < 0.01). After adjusting for baseline characteristics, the refractory gout cohort incurred an incremental total annual healthcare cost of $10,222 where 40% of the annual medical cost was for gout-related care compared with control cohort (P < 0.01). Patients with refractory gout have a significant economic burden compared with a gout-free population.

    Background Serum lactate dehydrogenase is a non-specific marker for lymphoma whose prognostic significance is well established for both indolent and aggressive lymphomas at the time of diagnosis. The performance characteristics of this enzyme in predicting relapse in patients with diffuse large B-cell lymphoma has not been well studied. Methods This study compared serum lactate dehydrogenase levels in 27 patients with diffuse large B-cell lymphoma who relapsed after sustaining a complete response versus 87 patients who did not relapse. For relapsed patients, the serum lactate dehydrogenase level at relapse was compared with the level three months before (considered baseline). For non-relapsed patients, the last two levels during follow-up were compared. For statistical analysis the T-test was used to compare differences in mean values between groups. The sensitivity, specificity, positive and negative predictive values for serum lactate dehydrogenase in detecting relapse compared to confirmatory imaging were calculated. Results At relapse, only 33% patients had increases in serum lactate dehydrogenase above the upper limit of normal. The mean increase was 1.2-fold above the upper limit of normal for relapsed vs. 0.83 for those who did not relapse (p-value = 0.59). The mean increase in serum lactate dehydrogenase, from baseline, was 1.1-fold in non-relapsed vs. 1.3 in relapsed patients (p-value = 0.3). The likelihood ratio of relapse was 4.65 for patients who had 1.5-fold increases in serum lactate dehydrogenase above baseline (p-value = 0.03). The sensitivity, specificity, positive and negative predictive values of 1.5-fold increases for detecting relapse, compared to clinical and imaging findings were 0.18, 0.95, 0.55, and 0.79, respectively. Conclusion A 1.5-fold increase in serum lactate dehydrogenase, over a period of 3 months, is associated with increased likelihood of relapse from diffuse large B-cell lymphoma. PMID:23904809

    Objectives To determine whether serum Cystatin C (CysC) and NTproBNP have prognostic value among patients with long-standing chronic lung disease. Design Prospective, observational, non-interventional study. Setting CysC and NTproBNP are prognostic markers in several cardiac conditions. In addition, CysC acts as an antiprotease following Cathepsin activation, which has been involved in the pathogenesis of chronic obstructive pulmonary disease. Participants Patients with a basal functional status of II-IV (NYHA), admitted for an acute exacerbation of chronic pulmonary diseases and no previous history of symptoms related to pulmonary hypertension or heart failure. Main outcome measures NTproBNP and CysC were determined at admission in 107 patients with acute exacerbation of chronic lung disease. During 12-month follow-up, mortality, new hospital admissions and prescription of diuretics were recorded. Results During follow-up there were eight patient deaths (7.5%). Mean NTproBNP among the deceased was 1510.20 pg/mL (95% CI 498.44–4628.55) vs 502.70 pg/mL (95% CI 395.44–645.48) among survivors (p = 0.01). Twenty-seven patients (25%) were prescribed loop diuretics. Mean concentration of CysC was 1.45 mg/dL (95% CI 1.21–1.69 mg/dL) vs 1.17 mg/dL (95% IC 1.09–1.25 mg/dL) in those not prescribed (p = 0.004). NTproBNP concentration was 837.14 pg/mL (95% CI 555.57–1274.10 pg/mL) in patients prescribed diuretics vs 473.42 pg/mL (95% CI 357.80–632.70 pg/mL) in those not prescribed (p = 0.03). Kaplan-Meier analysis revealed a significant difference between death and diuretic prescription during follow-up when cut-off value for NTproBNP was 550 pg/mL (p = 0.03 and p = 0.02, respectively). For 1.16mg/dL of CsysC, a significant difference was only observed in diuretic prescription (p = 0.007). Conclusions In patients with chronic respiratory diseases NTproBNP has predictive value in terms of mortality whereas CysC does not. However, it is still possible that both can

    Do differences in rates of use among managed care and Fee-for-Service Medicare beneficiaries reflect selection bias or successful care management by insurers? I demonstrate a new method to estimate the treatment effect of insurance status on health care utilization. Using clinical information and risk-adjustment techniques on data on acute admission that are unrelated to recent medical care, I create a proxy measure of unobserved health status. I find that positive selection accounts for between one-quarter and one-third of the risk-adjusted differences in rates of hospitalization for ambulatory care sensitive conditions and elective procedures among Medicare managed care and Fee-for-Service enrollees in 7 years of Healthcare Cost and Utilization Project State Inpatient Databases from Arizona, Florida, New Jersey and New York matched to Medicare enrollment data. Beyond selection effects, I find that managed care plans reduce rates of potentially preventable hospitalizations by 12.5 per 1,000 enrollees (compared to mean of 46 per 1,000) and reduce annual rates of elective admissions by 4 per 1,000 enrollees (mean 18.6 per 1,000).

  1. Clinical Utility of a New Automated Hepatitis C Virus Core Antigen Assay for Prediction of Treatment Response in Patients with Chronic Hepatitis C

    Hepatitis C virus core antigen (HCV Ag) is a recently developed marker of hepatitis C virus (HCV) infection. We investigated the clinical utility of the new HCV Ag assay for prediction of treatment response in HCV infection. We analyzed serum from 92 patients with HCV infection who had been treated with pegylated interferon and ribavirin. HCV Ag levels were determined at baseline in all enrolled patients and at week 4 in 15 patients. Baseline HCV Ag levels showed good correlations with HCV RNA (r = 0.79, P < 0.001). Mean HCV Ag levels at baseline were significantly lower in patients with a sustained virologic response (SVR) than in those with a non SVR (relapse plus non responder) based on HCV RNA analysis (2.8 log10fmol/L vs. 3.27 log10fmol/L, P = 0.023). Monitoring of the viral kinetics by determination of HCV RNA and HCV Ag levels resulted in similarly shaped curves. Patients with undetectable HCV Ag levels at week 4 had a 92.3% probability of achieving SVR based on HCV RNA assay results. The HCV Ag assay may be used as a supplement for predicting treatment response in HCV infection, but not as an alternative to the HCV RNA assay. PMID:27510387

  2. Are community-living and institutionalized dementia patients cared for differently? Evidence on service utilization and costs of care from German insurance claims data

    PubMed Central

    2013-01-01

    Background Dementia patients are often cared for in institutional arrangements, which are associated with substantial spending on professional long-term care services. Nevertheless, there is little evidence on the exact cost differences between community-based and institutional dementia care, especially when it comes to the distinct health care services. Adopting the perspective of the German social security system, which combines Statutory Health Insurance and Compulsory Long-Term Care Insurance (payer perspective), our study aimed to compare community-living and institutionalized dementia patients regarding their health care service utilization profiles and to contrast the respective expenditures. Methods We analysed 2006 claims data for 2,934 institutionalized and 5,484 community-living individuals stratified by so-called care levels, which reflect different needs for support in activities of daily living. Concordant general linear models adjusting for clinical and demographic differences were run for each stratum separately to estimate mean per capita utilization and expenditures in both settings. Subsequently, spending for the community-living and the institutionalized population as a whole was compared within an extended overall model. Results Regarding both settings, health and long-term care expenditures rose the higher the care level. Thus, long-term care spending was always increased in nursing homes, but health care spending was comparable. However, the underlying service utilization profiles differed, with nursing home residents receiving more frequent visits from medical specialists but fewer in-hospital services and anti-dementia drug prescriptions. Altogether, institutional care required additional yearly per capita expenses of ca. €200 on health and ca. €11,200 on long-term care. Conclusion Community-based dementia care is cost saving from the payer perspective due to substantially lower long-term care expenditures. Health care spending is

    There is ongoing interest in optimizing basal insulin treatment by developing insulins with a flat pharmacological profile, a long duration of action (typically beyond 24 hours) and minimum day-to-day variation. Glargine-300 is a modified form of the long-acting insulin analog glargine in that it has been concentrated at 300 units/mL rather than the conventional 100 units/mL. Glargine-300 has a longer duration of action and a flatter pharmacological profile than original glargine-100. This property allows for more flexibility around the timing of administration, when injected once per day. Open-label studies in patients with diabetes have shown that treatment with glargine-300 achieves comparable glycemic control compared to treatment with glargine-100, albeit with consistently higher insulin requirements. These studies also showed that treatment with glargine-300 was associated with lower risks of nocturnal hypoglycemia in patients with type 2 diabetes, particularly those already on insulin, whereas data are mixed in insulin-naïve patients with type 2 diabetes or in patients with type 1 diabetes. Treatment with glargine-300 did not appear to affect the risk of overall hypoglycemia, whereas studies lacked sufficient power to investigate the effect on the risk of severe hypoglycemia. Future studies need to establish the role of glargine-300 in the treatment of diabetes alongside the other new long-acting insulin analog, insulin degludec, which was recently introduced to the market.

    Pain is a common complication after spinal cord injury with prevalence estimates ranging 77% to 81%, which highly affects a patient's lifestyle and well-being. In the current clinical setting paper-based forms are used to classify pain correctly, however, the accuracy of diagnoses and optimal management of pain largely depend on the expert reviewer, which in many cases is not possible because of very few experts in this field. The need for a clinical decision support system that can be used by expert and non-expert clinicians has been cited in literature, but such a system has not been developed. We have designed and developed a stand-alone tool for correctly classifying pain type in spinal cord injury (SCI) patients, using Bayesian decision theory. Various machine learning simulation methods are used to verify the algorithm using a pilot study data set, which consists of 48 patients data set. The data set consists of the paper-based forms, collected at Long Beach VA clinic with pain classification done by expert in the field. Using the WEKA as the machine learning tool we have tested on the 48 patient dataset that the hypothesis that attributes collected on the forms and the pain location marked by patients have very significant impact on the pain type classification. This tool will be integrated with an imaging informatics system to support a clinical study that will test the effectiveness of using Proton Beam radiotherapy for treating spinal cord injury (SCI) related neuropathic pain as an alternative to invasive surgical lesioning.

    We aimed to evaluate the importance of neck/thyromental distance in the diagnosis of moderate to severe obstructive sleep apnea (OSA) in sleep clinics. 185 patients (122 males, 63 females) referred to our sleep clinic with OSA symptoms were enrolled to the study. The patients had level-1 polysomnography (PSG). The neck circumference (N), thyromental distance (T), and STOP test were recorded in all patients. Using an obstructive AHI > 15 event/h on PSG as the cut-off, the best N/T ratio to find patients with OSA was calculated with the receiver operator curve analyses. The best cut-off for N/T was chosen as 4.6. We used Modified STOP test: STO-NT test in which P (for hypertension item) was replaced with N/T ratio. N/T ratio >4.6 was scored as "positive". Two positives out of four questions in STO-NT were scored as high risk for OSA. The OSA prevalence was 60 % for AHI > 15. The mean ratio of N/T was significantly different between groups with AHI > 15 and AHI ≤ 15. N and N/T ratio were moderately correlated with AHI. Sensitivity, specificity, negative predictive value, positive predictive value, and negative likelihood ratio of STOP test for AHI > 15 were 88.5, 28.4, 61.8, 65.4 % and 0.40, whereas 97.3, 23, 85, 65.9 % and 0.12 for STO-NT test, respectively. STO-NT test seems better than STOP test in determining patients who do not likely to have moderate to severe OSA in sleep clinics so can be preferred to decide on therapies other than CPAP in a short time.

    Abstract Approximately 3 million patients with symptoms suggestive of obstructive coronary artery disease (CAD) present to primary care offices in the United States annually, resulting in approximately $6.7 billion in cardiac workup costs. Despite wide application of existing diagnostic technologies, yield of obstructive CAD at invasive coronary angiography (ICA) is low. This study used a decision analysis model to assess the economic utility of a novel gene expression score (GES) for the diagnosis of obstructive CAD. Within a representative commercial health plan's adult membership, current practice for obstructive CAD diagnosis (usual care) was compared to a strategy that incorporates the GES test (GES-directed care). The model projected the number of diagnostic tests and procedures performed, the number of patients receiving medical therapy, type I and type II errors for each strategy of obstructive CAD diagnosis, and the associated costs over a 1-year time horizon. Results demonstrate that GES-directed care to exclude the diagnosis of obstructive CAD prior to myocardial perfusion imaging may yield savings to health plans relative to usual care by reducing utilization of noninvasive and invasive cardiac imaging procedures and increasing diagnostic yield at ICA. At a 50% capture rate of eligible patients in GES-directed care, it is projected that a commercial health plan will realize savings of $0.77 per member per month; savings increase proportionally to the GES capture rate. These findings illustrate the potential value of this new blood-based, molecular diagnostic test for health plans and patients in an age of greater emphasis on personalized medicine.

    Research to date regarding identification and management of hereditary breast and ovarian cancer syndrome (HBOC) in the U.S. has been confined primarily to academic center-based studies with limited patient engagement. To begin to understand and address the current gaps and disparities in delivery of services for the appropriate identification and optimal risk management of individuals with HBOC, we designed and have initiated the American BRCA Outcomes and Utilization of Testing (ABOUT) Study. ABOUT relies on a collaborative patient advocacy, academic and industry partnership to recruit and engage U.S. individuals who are at increased risk for HBOC and investigate their experiences, decisions and outcomes. It utilizes an extensive research infrastructure, including an interactive web-based data system and electronic interfaces for secure online participation and automated data exchange. We describe the novel recruitment approach that was designed for collaboration with a national commercial health plan partner to identify all individuals for whom a healthcare provider orders a BRCA test and mail to each individual an invitation to participate and study packet. The study packet contains detailed information about the study, a baseline questionnaire and informed consent for participation in the study, for release of relevant medical and health plan records and for ongoing research engagement. This approach employs patient-reported, laboratory-reported and health plan-reported outcomes and facilitates longitudinal engagement. We believe that the type of innovative methodology and collaborative framework we have developed for ABOUT is an ideal foundation for a patient-powered research network. This approach can make substantial contributions to identifying current and best practices in HBOC, leading to improved strategies for clinical care and optimal health outcomes among individuals with high inherited risk for cancer.

    We assessed the usefulness of in situ hybridization with a DNA probe to the area of chromosome 17 at p11.2 as a diagnostic tool for screening for Charcot Marte Tooth 1A (CMT 1A). In situ hybridization with a probe to 17p11.2 was performed on fixed lymphocytes from the following groups of individuals: (1) normal controls; (2) patients evoking a strong clinical suspicion of CMT 1A; and (3) 3 families with an apparent autosomal dominant peripheral neuropathy of unknown diagnoses. Group 2 patients had evidence of demyelination as defined by nerve conduction of less that 50% of the normal mean or terminal latency greater than 50% of the normal mean in conduction studies. Analysis of interphase cells hybridized with a cosmid DNA probe to 17p11.2 requires inclusion of a normal control with each trial and masked observer. Due to the size of the target DNA and the nature of the centromeric heterochromatin, the scoring of this probe is more subjective than centromere probes. For example, if the two 17 chromosomes are decondensed as in interphase, two tandem signals may be visualized as one. Results from duplication positive patients demonstrate a large proportion of cells with two closely aligned, but separate, signals with an additional single signal. Normal results demonstrate a majority of cells with two separate signals representing both normal homologues. None of the 3 families with questionable diagnosis revealed a duplication at the region, reinforcing our belief that a clinical diagnosis is the most discriminating tool available for diagnosis of CMT 1A. We concur with Boylan that molecular analysis for CMT 1A is useful for establishing a diagnosis of CMT 1A, but is not a primary differential diagnostic test. The yield in screening patients without physiologic evidence of demyelination is likely to be low. We further find that the use of in situ hybridization is a simple method of performing the duplication analysis.

    Single ventricle anomalies are a challenging set of congenital heart defects that require lifelong clinical management due to progressive decline of cardiovascular function. Few therapeutic devices are available for these patients, and conventional blood pumps are not designed for the unique anatomy of the single ventricle physiology. To address this unmet need, we are developing an axial flow blood pump with a protective cage or stent for Fontan patients. This study investigates the 3-D particle image velocimetry measurements of two cage designs being deployed in a patient-specific Fontan anatomy. We considered a control case without a pump, impeller placed in the inferior vena cava, and two cases where the impeller has two protective stents with unique geometric characteristics. The e
