Purpose: To examine whether a collaborative to improve asthma care influences process and outcomes of care in adult asthmatics.
Method: Pre- and Post-intervention evaluation of 185 patients in 6 intervention clinics and 3 matched control sites that participated in the evaluation of the Institute for Healthcare Improvement Breakthrough Series (BTS) Collaborative for asthma care. The intervention consisted of three two-day educational sessions for teams dispatched by participating sites followed by three “action” periods over the course of a year.
Results: Overall process of asthma care improved significantly in the intervention compared to the control group (change of 10% versus 1%, p=0.003). Patients in the intervention group were more likely to attend educational sessions (20% versus 5%, p=0.03). Having a written action plan, goal setting, peak flow monitoring and use of long-term controller medications increased between 2% and 19% (not significant) and asthma-related knowledge was unchanged for the two groups. Patients in the BTS collaborative were significantly more likely to be satisfied with provider communication (62% vs. 39%, p=0.02). HRQoL, asthma specific quality of life, number of bed days due to asthma related illness and acute service use were not significantly different between the two groups.
Conclusions: The intervention was associated with improved process of care measures that have been linked with better outcomes. Patients benefited through increased satisfaction with communication. Follow-up of patients who participated in the intervention may have been too brief to detect significant improvement in health-related outcomes.
