Avaliação da adesão dos portadores de doença pulmonar obstrutiva crônica ao tratamento com utilização de inaladores de pó seco

Abstract

Chronic Obstructive Pulmonary Disease (COPD) is a syndrome characterized by progressive airflow limitation that is associated with abnormal lung inflammatory responses to some types of particles. The most recent statistics show that patients with COPD represent a great impact on economic and social expenses. The present work aims to characterize the sociodemographic profile, adherence to drug therapy and the performance of the use of dry powder inhalation devices by patients treated at an ambulatory clinic of a tertiary hospital specializing in pulmonary and cardiovascular diseases located in the city of Fortaleza - CE. This is a crosssectional, quantitative and analytical study where 110 predominantly male individuals were interviewed with an average age of approximately 71 years and who had studied only up to incomplete elementary school. The average number of medications was 4.98 per respondent, and 79.09% had at least one associated comorbidity. The mean prevalence found for treatment adherence was 56.88%. As for the use of dry powder inhalation devices, 81.65% used the Aerolizer device while only 18.35% used the Turbuhaler device. In the evaluation of the use of these devices, an average of 0.872 errors per patient was verified, and only 33.94% of the patients did not make any errors when using inhaled devices. Through these data, further studies are needed to elucidate other hypotheses evaluating the concrete influence of other variables on treatment adherence, and thus it is possible to delineate new strategies to enhance actions to improve adherence and continuous evaluation of treatment, in order to benefit the patient and their quality of life
