Quality improvement initiatives improve hypertension care among veterans

We implemented a quality improvement initiative to improve hypertension care at Veterans Affairs-Tennessee Valley Healthcare System. We implemented multiple interventions among 2 teaching hospitals, 5 community-based outpatient clinics, and 4 contract clinic sites. Goals of the program were to (1) improve measurement and documentation of blood pressure (BP), (2) initiate outpatient patient education, (3) emphasize VA/Department of Defense hypertension treatment algorithms to providers, (4) emphasize external peer review program performance goals, and (5) initiate feedback of each clinic's performance. The primary outcome was the proportion of patients seen each week with a diagnosis of hypertension who had their last available BP in control (< or =140/90 mm Hg). Observation time was 40 weeks (14 weeks preintervention, 8 weeks intervention implementation, and 18 weeks postintervention), during which there were 55 586 unique clinic visits for hypertension. After intervention deployment, there was an absolute improvement of 4.2% in BP control (preintervention 61.5% [12 245/19 908] versus postintervention 65.7% [15 809/24 059], P
