ABSTRACT

Aims  To determine the effect of an intervention to improve alcohol screening and brief counseling for hypertensive patients in primary care.

Design  Two-year randomized, controlled trial.

Setting/participants  Twenty-one primary care practices across the United States with a common electronic medical record.

Intervention  To promote alcohol screening and brief counseling. Intervention practices received site visits from study personnel and were invited to annual network meetings to review the progress of the project and share improvement strategies.

Measurements  Main outcome measures included rates of documented alcohol screening in hypertensive patients and brief counseling administered in those diagnosed with high-risk drinking, alcohol abuse or alcohol dependence. Secondary outcomes included change in blood pressure among patients with these diagnoses.

Findings  Hypertensive patients in intervention practices were significantly more likely to have been screened after 2 years than hypertensive patients in control practices [64.5% versus 23.5%; adjusted odds ratio (OR) = 8.1; 95% confidence interval (CI) 1.7–38.2; P < 0.0087]. Patients in intervention practices diagnosed with high-risk drinking, alcohol abuse or alcohol dependence were more likely than those in control practices to have had alcohol counseling documented (50.5% versus 29.6%; adjusted OR = 5.5, 95% CI 1.3–23.3). Systolic (adjusted mean decline = 4.2 mmHg, P = 0.036) and diastolic (adjusted mean decline = 3.3 mmHg, P = 0.006) blood pressure decreased significantly among hypertensive patients receiving alcohol counseling.

Conclusions  Primary care practices receiving an alcohol-focused intervention over 2 years improved rates of alcohol screening for their hypertensive population. Implementation of alcohol counseling for high-risk drinking, alcohol abuse or alcohol dependence also improved and led to changes in patient blood pressures.
