This study showed a direct correlation between estimated partial compliance and hospitalization risk among patients with schizophrenia across a continuum of compliance behavior.

Background: There are few published data on the clinical characteristics of hyperhidrosis. Objective: To describe the functional impairment caused by primary focal hyperhidrosis. Methods: Patients with hyperhidrosis (n = 345) were enrolled at the Department of Dermatology, University of Würzburg. Controls (n = 154) were a convenience sample of subjects without hyperhidrosis. Hyperhidrosis characteristics, health-related quality of life and functional impairment were assessed. Results: Patients with axillary hyperhidrosis reported a later age at onset and a higher prevalence of a family history of hyperhidrosis than patients with palmar hyperhidrosis. Sixty-three percent of patients reported occupational impairment related to hyperhidrosis. Hyperhidrosis patients reported emotional and physical impairment, with a greater proportion of the axillary group reporting impairment. More than 50% of patients reported moderate to extreme impairment in personal relationships and in social situations. Conclusion: Primary focal hyperhidrosis is a serious medical condition, affecting work productivity, daily activities, emotional well-being and personal relationships.

BackgroundThe purpose of this study was to compare two methods of adherence calculation using administrative data for patients with multiple sclerosis (MS) who are prescribed disease-modifying drugs.MethodsPharmacy-billed disease-modifying drug prescription claims were selected from the 2007–2008 LifeLink™ Health Plan Claims Database. The index date was the first disease-modifying drug prescription claim. Two cohorts were created: all patients with a disease-modifying drug claim in 2007 and a subset with continuous eligibility for 12 months post-index. Adherence was calculated across all disease-modifying drugs for 12 months post-index. Medication possession ratios (MPRs) with variable (start to end of therapy) and fixed (365 days) duration denominators were calculated. Variable MPR was calculated by summing days supply from the first to the last prescription (inclusive) divided by time between the last prescription date plus days supply and the first prescription date. Variable MPR was evaluated for all patients and the continuously eligible cohort. Fixed MPR used the same numerator but divided by 365 days of follow-up and evaluated only for the continuously eligible cohort.ResultsThere were 3405 patients with MS and a disease-modifying drug claim in 2007 and 2145 in the continuously eligible cohort. Means for variable MPR ranged from 87.5% ± 16.6% for the continuously eligible cohort to 90.5% ± 16.0% for the 2007 cohort. The comparable value for fixed MPR was 78.0% ± 28.2% for the continuously eligible cohort. Fixed MPR gave a consistently lower rate of adherence than variable MPR at an 80% adherence threshold.ConclusionDifferent adherence measures can yield different outcomes, especially when using different eligibility criteria. These results demonstrate the importance of full disclosure of methods used for calculations and specification of the study population.

Our analyses across asthma, COPD and patients with mixed respiratory disease (with features of both COPD and asthma), study designs and data sets lead us to conclude that the PASAPQ is a practical, valid, reliable and responsive instrument for measuring respiratory device satisfaction. Furthermore, a difference in satisfaction scores between treatment groups of 10 points is, conservatively, a difference that is meaningful to patients.
