Brief Summary:
This project is a VA HSR&D-funded Quality Enhancement Research Initiative (QUERI) project to translate into practice evidence about clinical management of primary hypertension. The project aims to contribute to quality improvement of care for patients with primary hypertension. The project implemented a clinical decision support (CDS) system for primary care clinicians and evaluated the implementation by studying the following: impact on the clinicians' prescribing and their patients' blood pressures; the clinician satisfaction with the CDS; and organizational factors in the implementation.

Arm Intervention/treatment
Experimental: ATHENA-CDS-HTN plus Guideline Link
ATHENA-CDS-HTN plus Guideline Link. ATHENA-CDS-HTN display on the cover sheet of electronic health record, plus link to the guidelines
Other: ATHENA-CDS-HTN plus Guideline Link
ATHENA display provides guideline-based recommendations to clinicians at the time of patient care.
Guideline Link Only
Guideline Link Only. Link to The Seventh Report of the Joint National Committee on Prevention Detection and Treatment of High Blood Pressure (JNC7) and to VA-Department of Defense (DoD) hypertension guidelines
Other: Guideline Link Only
Primary care providers were sent, once, a link (URL) to the VA/DoD and JNC7 hypertension guidelines.



Primary Outcome Measures :
  1. Mean Percentages of Events After Index Visit to Primary Care by Patient [ Time Frame: up to one year after index visit ]
    The outcome measure was mean percentages of Events after index visit to primary care by patients. The Events were the first event in the patient record after the index clinic visit for the patient, as follows. Event 1 is intensification of pharmacotherapy for hypertension. Event 2 is patient achieves below-target blood pressure (BP). Event 3 is patient does not achieve below-target BP nor is there intensification of pharmacotherapy for hypertension. Event 4 is patient does not achieve BP target, does not have intensified pharmacotherapy, and does not return for further BP measurements. Each patient was assigned one and only one Event. If a patient has pharmacotherapy intensified and also achieved BP below-target, the patient was assigned to whichever happened first. An initial model fitting all 4 events did not detect a difference by study arm for mean percentage of Event 4; final findings are based on a denominator of Events 1 - 3.
