Self-reporting to Measure Treatment Adherence in Patients with Chronic Obstructive Pulmonary Disease: A Systematic Review

Objective: The purpose of this systematic review was to conduct asynthesis of a set of tools to measure adherence to treatment suitable for COPD patients, treatment adherence level of patients with COPD, and provide recommendations for nurses to determine appropriate treatment adherence self-report scales in COPD patients. Material and Methods: Predefined keywords were identified by using a PICO format. Keywords included "Chronic obstructive pulmonary diseases" or "treatment adherence self-report scale". Ten articles met all eligible criteria for review from a total of 833 published studies. Results: Among the 10 articles, most studies were conducted in Europe (50%) and Asia (30%) and used a crosssectional study design (90%). The self-reported scales of treatment adherence in COPD patients icluded MARS (20%), MMAS (50%), TAI (10%), MTA (10%) and self-report adherence quesionnaire (10%). The level of non-adherence to COPD treatment ranged from 16.5% to 74.1%. Conclusion: Several self-reported scales that are most frequently used in COPD patient treatment adherence research weer evaluated for this review. Before selecting any adherence scale, several factors must be taken into account.
