Abstract
The authors evaluated the treatment of isolated systolic hypertension based on medical record review of charts between 1998 and 1999 in a multispecialty physician practice group. Two age-stratified random samples of ambulatory medical records were examined (393 patients aged > or =65 years and 251 patients aged 50-64 years). The samples corresponded to the practices of 35 primary care physicians who were surveyed about their hypertension care. Isolated systolic hypertension was defined as systolic blood pressure > or =140 mm Hg and diastolic blood pressure <90 mm Hg. Results showed that isolated systolic hypertension represented 76% and 45% of uncontrolled blood pressure in the older and middle-aged samples, respectively. Isolated systolic hypertension was often undiagnosed and untreated. Physicians reported treatment thresholds and goals that were significantly less aggressive for their patients > or =65 years of age. Physician awareness and treatment of isolated systolic hypertension have not yet caught up with consensus guidelines, and older patients may be affected most by this gap.
