Adherence to inhaled therapies of COPD patients from seven Latin American countries: The LASSYC study.

ABSTRACT:

Background

This study assessed the adherence profiles to inhaled therapies and the agreement between two patient self-report adherence methods in stable COPD lpatients from seven Latin American countries.

Methods

This observational, cross-sectional, multinational, multicenter study involved 795 COPD patients (post-bronchodilator forced expiratory volume in 1 second/forced vital capacity [FEV1/FVC] <0.70). Adherence to inhaled therapy was assessed using the specific Test of Adherence to Inhalers (10-item TAI) and the generic 8-item Morisky Medication Adherence Scale (MMAS-8) questionnaires. The percentage agreement and the kappa index were used to compare findings.

Results

59.6% of patients were male (69.5±8.7 years); post-bronchodilator FEV1 percent predicted was 50.0
