Abstract

Adherence to COPD treatment plays a crucial role in patient health outcomes. Understanding the correlation between treatment adherence and health status is vital for clinicians to develop effective disease management strategies. This study aimed to examine treatment adherence and its impact on the health status of COPD patients, specifically focusing on the effects of adhering to inhaled medications and breathing exercises. A cross-sectional study involving 420 outpatients diagnosed with COPD was conducted. The study encompassed administering questionnaires, observing patient breathing exercises, and measuring ventilatory function. Results showed that only 36.9% of participants adhered to treatment, with 44.7% following inhaler protocols and 36.9% regularly engaging in breathing exercises. The patients who were non-adherent exhibited a 0.3-fold increase in disease severity compared to the adherent group (p = .002). These findings suggest that consistent adherence to treatment, including inhaled medications and breathing exercises, may positively affect health status by reducing disease severity and airway obstruction in COPD patients. To address this, we recommend that home care clinicians implement a post-discharge assessment and intervention program. This program should focus on educating patients about the importance of treatment adherence and promoting behaviors that reinforce adherence to prescribed therapies.
