Abstract Introduction While the benefits of pulmonary rehabilitation programs (PR) in COPD have been demonstrated, poor adherence, related with worse clinical outcomes, is common. Objective The purpose of this study was to examine causes for drop-out during a 12-week multidisciplinary pulmonary rehabilitation program and to investigate the characteristics of patients with poor adherence, with special emphasis on functional and clinical characteristics. Method A prospective study was performed between February and November 2015 in 83 COPD patients enrolled in an outpatient program of 36 strength+resistance training sessions. Ambulances were provided to facilitate access to the clinic. Patients were divided into: adherent (A) (attended at least 70% of the program) or non-adherent (NA) (at least one session). Results A total of 83 patients were evaluated and 26 excluded; 15.7% refused to participate. The drop-out rate was 38.5%. The main causes were low motivation and transport problems. Lower forced vital capacity (NA, 58.9% vs A, 67.8%; P =.03), worse results on submaximal exercise test (NA, 6.2 min vs A, 9.2 min; P =.02), in total distance walked (NA, 42.6 vs A, 56.5; P =.03) and VO2 in ml/min/kg (NA, 11.4 vs A, 13.6; P =.03) and in ml/min (NA, 839 vs A, 1020; P =.04) were found in the non-adherent group. This group also showed higher use of oral steroids (NA, 23.8% vs A, 2.9%; P =.01). Conclusions More than 1/3 of patients leave programs. The main causes are related to motivation and transport. The patients who dropout are those with worse functional tests, more exacerbations, steroids and smoking habit.
