High blood pressure diagnosis and treatment: consensus recommendations vs actual practice.

Diagnostic and treatment practices of institutional facilities treating high blood pressure in New York City were surveyed by mail in 1978. Respondents were adhering to the treatment recommendations of the Joint National Committee on Detection, Evaluation and Treatment of High Blood Pressure. Ninety-two per cent of respondents reported 90-104 mm Hg as the diastolic blood pressure level at which drug therapy was initiated, indicating a more aggressive approach than was warranted by the information available at the time of the survey.
