Abstract:

BACKGROUND: Compared to White patients in the United States, Black patients have a higher prevalence of hypertension and more severe forms of this condition. OBJECTIVE: To decrease racial disparities in blood pressure (BP) control among Black veterans with severe hypertension within a regional network of Veterans Affairs Medical Centers (VAMCs). METHODS: Health system leaders, clinicians, and health services researchers collaborated on a 12-month quality improvement (QI) project to: (1) examine project implementation and the QI strategies used to improve BP control and (2) assess the effect of the initiative on Black-White differences in BP control among veterans with severe hypertension. RESULTS: Within 9 participating VAMCs, the most frequently used QI strategies involved provider education (n = 9), provider audit and feedback (n = 8), and health care team change (n = 7). Among 141,124 veterans with a diagnosis of hypertension, 9,913 had severe hypertension [2,533 (25.6%) Black and 7380 (74.4%) White]. Over the course of the project, the proportion of Black veterans with severe hypertension decreased from 7.5% to 6.6% (p = .002) and the racial difference in proportions for this condition decreased 0.9 percentage points, from 2.9% to 2.0% (p = .01). CONCLUSIONS: A multicenter, equity-focused QI project in VA reduced the proportion of Black veterans with severe hypertension and ameliorated observed racial disparities for this condition. Embedding health services researchers within a QI team facilitated an evaluation of the processes and effectiveness of our initiative, providing a successful model for QI within a learning health care system.
