Posting guidelines: a practical and effective way to promote appropriate hypertension treatment

Area of Science:

• Internal Medicine
• Clinical Practice Guidelines
• Hypertension Management

Background:

• Hypertension remains undertreated in the US, with physicians underusing recommended medications despite available guidelines.
• Physician adherence to established hypertension treatment protocols is suboptimal.

Purpose of the Study:

• To assess the impact of readily accessible clinical guidelines on physician prescribing habits and patient blood pressure control.
• To evaluate changes in the utilization of antihypertensive medications and overall treatment costs.

Main Methods:

• Summarized hypertension treatment guidelines were posted in a primary care clinic. Data from 253 hypertensive patients were analyzed over 16 months.
• Physician prescribing patterns, drug costs, and patient blood pressures were compared pre- and post-guideline implementation.

Main Results:

• The proportion of patients achieving blood pressure < 140/90 mm Hg increased significantly from 41% to 58% (p = .001).
• Median systolic and diastolic blood pressures decreased, and physicians prescribed more recommended, higher doses of specific drugs (hydrochlorothiazide, lisinopril), and less expensive options.
• Total antihypertensive drug cost per patient saw a slight increase.

Conclusions:

• Practical and accessible clinical guidelines can effectively modify physician behavior.
• Regular exposure to simplified guidelines improves patient care and hypertension management outcomes.
