Does care at Veterans Affairs clinics improve blood pressure control and reduce ethnic disparities among hypertensive men compared to non-VA sites?
Equal access to healthcare, such as that provided by the Veterans Affairs system, significantly reduces ethnic disparities in blood pressure control between African American and white hypertensive men.
Absolute Event Rate: 6.2% vs 10.2%
p-value: p=<.01
BACKGROUND: Differential access to health care may contribute to lower blood pressure (BP) control rates to under 140/90 mm Hg in African American compared with white hypertensive patients, especially men (26.5% vs 36.5% of all hypertensive patients in the National Health and Nutrition Examination Survey 1999-2000). The Department of Veterans Affairs (VA) system, which provides access to health care and medications across ethnic and economic boundaries, may reduce disparities in BP control. METHODS: To test this hypothesis, BP treatment and control groups were compared between African American (VA, n = 4379; non-VA, n = 2754) and white (VA, n = 7987; non-VA, n = 4980) hypertensive men. RESULTS: In both groups, whites were older than African Americans (P<.05), had lower BP (P<.001), and had BP controlled to below 140/90 mm Hg more often on their last visit (P<.01). Blood pressure control to below 140/90 mm Hg was comparable among white hypertensive men at VA (55.6%) and non-VA (54.2%) settings (P = .12). In contrast, BP control was higher among African American hypertensive men at VA (49.4%) compared with non-VA (44.0%) settings (P<.01), even after controlling for age, numerous comorbid conditions, and rural-urban classification. African American hypertensive men received a comparable number of prescriptions for BP medications at VA sites (P = .18) and more prescriptions at non-VA sites than did whites (P<.001). African Americans had more visits in the previous year at VA sites (P<.001) and fewer visits at non-VA sites (P<.001) compared with whites. CONCLUSIONS: The ethnic disparity in BP control between African Americans and whites was approximately 40% less at VA than at non-VA health care sites (6.2% vs 10.2%; P<.01). Ensuring access to health care could constitute one constructive component of a national initiative to reduce ethnic disparities in BP control and cardiovascular risk.
Shakaib U. Rehman (2005) conducted an observational in Hypertension (n=20,100). Veterans Affairs (VA) health care system vs. Non-VA health care sites was evaluated on Ethnic disparity in blood pressure control to below 140/90 mm Hg between African Americans and whites (p=<.01). Care at Veterans Affairs clinics was associated with a 40% smaller ethnic disparity in blood pressure control between African American and white men compared to non-VA sites (6.2% vs 10.2%; P<.01).
