ASSESSMENT THE SATISFACTION AND ADHERENCE OF INHALATION DEVICES AMONG PATIENTS WITH COPD AND ASTHMA AT RESPIRATORY CENTER, BACH MAI HOSPITAL

Abstract

Introduction: Satisfaction with the inhaler is an important determinant of treatment adherence in patients with chronic obstructive pulmonary disease (COPD) and asthma. Poor adherence to inhaled therapy is common in those patients. This study describes the level of satisfaction and adherence to inhaler devices among patients with COPD and asthma and determines the variables associated with high satisfaction and adherence. Methods: A cross-sectional study of 260 Vietnamese patients (194 with COPD and 66 with asthma) was conducted. Satisfaction was assessed with the Feeling of Satisfaction with Inhaler (FSI-10) questionnaire. Adherence to inhaled therapy was assessed with the Test of Adherence to Inhaler (TAI). Results: The study population was categorized according to a median FSI-10 score as high (59.6%) and low (40.4%) satisfaction with their inhaler. Educational level, diagnosis and the level of adherence were significantly associated with high inhaler satisfaction. The asthma group was significantly more satisfied with the inhaler (mean FSI-10 score: 43.4 (±0.5) vs. 40.2 (±0.4), p<0.001). Over half (59.6%) of the total participants were classified in the poor adherence group. In that, poor adherence group in COPD sample and asthma sample accounted for 63.9% and 50% respectively. Duration of diagnosis and duration of the time in the Program were significantly associated with the level of adherence. Conclusions: High patient satisfaction with the inhaler was related to educational level, diagnosis and adherence. Duration of diagnosis, the time in the program of the participant and number of inhaler using were associated with the level of adherence.
