This project measured the effect of a multifaceted intervention on health care provider identification and treatment of undiagnosed hypertensive patients. The intervention comprised provider education, audit, and feedback. The primary outcomes were pre-/postintervention differences in the proportion of patients presenting with elevated blood pressure who were (1) identified, (2) given blood pressure measurements, (3) counseled regarding behavior change, (4) prescribed medications, and (5) advised of the need for follow-up. These 5 behaviors were selected based on the recommendations in the seventh report of the Joint National Committee on Prevention, Detection, Evaluation, and Treatment of High Blood Pressure.

Rates of all 5 outcomes improved significantly after the intervention, with prevalence differences ranging from 5% to 25%. However, despite increases, rates for each behavior remained low. At no point during the study were all 5 practitioner behaviors documented for an individual patient.

In conclusion, while an intervention composed of education and practitioner audit and feedback improved practitioner behaviors in treating patients with elevated blood pressure, additional interventions are needed to bring practitioner behaviors up to the level of JACHO standards.
