Hypertension management practices and patient health outcomes in a managed care setting were evaluated. Health-system pharmacists analyzed plan medical and pharmacy claims data for September 1, 1998, to August 31, 1999, to identify hypertensive enrollees (n = 23,316). Reviews of pharmacy claims and medical charts of a sample of hypertensive patients (n = 374) determined blood pressure control status, prevalence of cardiovascular risk factors, and comorbidities. The majority of patients treated for hypertension (66%) did not achieve blood pressure control. Analysis revealed a high prevalence of cardiovascular risk factors among hypertensive patients, with 92.2% of study patients having two or more risk factors. Reviews of 132,512 pharmacy claims revealed that one half of all prescribed therapies were for monotherapy, and 21% of hypertensive patients were prescribed combination therapy with two different agents. Data from a large managed care organization revealed that more than half of all hypertensive patients had inadequate blood pressure control. A quality improvement program for hypertension care that can improve patient health outcomes must educate patients and health care providers about the implications of the disease, identify patients with compelling comorbidities, evaluate pharmacologic regimens, and recommend therapeutic changes when necessary.
