Hypertension treatment and control among 28 physician practices across the United States: results of the Hypertension: Assessment of Treatment to Target (HATT) Study.

Chart reviews were conducted at 28 US physician practices to evaluate blood pressure (BP) management. The cross-sectional study included 8250 adult patients diagnosed with hypertension. The primary outcome variable was BP control (BP <140/90 mm Hg for nondiabetic and <130/80 mm Hg for diabetic patients). Mean body mass index was 30.9 kg/m(2), 49% were obese, 54% were women, mean age was 64.9 years, and 25% had diabetes. Mean BP was 132.2/77.8 mm Hg, and 55.8% of study participants had controlled BP. Patients with uncontrolled BP were more likely to be obese or African American, and more than twice as likely to have diabetes. Almost 1 in 5 nondiabetic patients (18%), and 38% of diabetic patients, were above goal BP by >10 mm Hg systolic or >5 mm Hg diastolic; among these patients, 36% used 0 or 1 antihypertensive medication, and 32% used 2 medications. Opportunity exists to improve BP control in this population.
