A101-10 Implementation of Quality Standard in Quality Improvement Program Enhances Adherence to Inhaled Therapy in Patients With Chronic Obstructive Pulmonary Disease
Randomized trial assesses quality standard impact on inhaled therapy adherence in COPD patients, suggesting significant improvement.
Key Points
This study aims to evaluate how implementing a Quality Standard within a Quality Improvement Program affects adherence to inhaled therapy in COPD patients.
Prospective, multi-center Quality Improvement Program study (NCT05638646) involving 1055 COPD patients across 40 hospitals in China.
Patients assigned to either Quality Standard group (n = 524) or control group (n = 531) to assess adherence improvements every 12 weeks.
Primary outcomes measured included inhaler therapy adherence, correct inhaler technique, and non-pharmacological treatment.
Inhaled therapy adherence increased by 30.6% in the QS group versus 7.1% in the control group after 48 weeks (P < 0.05).
Proportion of days covered (PDC) ≥70% was reported by 91.1% in the QS group compared to 77.2% in the control group (P < 0.05).
Correct inhaler use improved significantly from 56.0% to 90.7% in the QS group, versus an increase from 67.8% to 80.8% in the control group (P < 0.05).
