Impact of positive and negative beliefs about inhaled corticosteroids on adherence in inner-city asthmatic patients

摘要: Background Daily inhaled corticosteroid (ICS) use is the cornerstone of asthma management, although it often suboptimal, especially in inner-city populations. Objective To assess impact potentially modifiable medication beliefs on adherence with ICS therapy across time. Methods Asthma history, beliefs, and were determined a prospective, observational cohort. Medication based self-regulation self-efficacy theory. Self-reported was assessed using Adherence Reporting Scale, validated 10-item instrument, at baseline 1 3 months. Repeated-measures multivariable regression identified independently associated time after adjusting for age, sex, race, severity. Results The 261 patients low-income minorities high rates hospitalization, emergency department visits, intubation, oral use. stable time, 70% saying that they used all or most when asymptomatic. Most (82%) thought important to asymptomatic, 49% worried about side effects 37% becoming addicted. Although 82% felt confident ICS, 7% their regimen hard follow. In analyses, odds increased those who asymptomatic (odds ratio [OR], 4.15) (OR, 2.23) decreased by worries 0.52) feeling follow 0.48). Conclusions Several positive negative adherence. Eliciting addressing these may help improve outcomes.
