Brief intervention in a primary care setting for hazardous drinkers

Area of Science:

• Public Health
• Behavioral Science
• Primary Care Medicine

Background:

• Alcohol consumption among moderate to heavy drinkers poses a significant public health concern.
• Identifying and intervening with hazardous drinkers in primary care settings is crucial for reducing alcohol-related harm.

Purpose of the Study:

• To evaluate the effectiveness of a brief, one-time motivational intervention for reducing alcohol consumption in hazardous drinkers within a primary care setting.
• To assess the impact of the intervention on various drinking behaviors and healthcare utilization.

Main Methods:

• A randomized controlled trial involving 516 hazardous drinkers identified via the AUDIT screening questionnaire.
• Intervention group received brief clinician advice, a 15-minute motivational session, and printed materials.
• Control group received standard care.

Main Results:

• Intervention subjects reported significantly fewer drinking days per week at both six (2.8 vs 3.3, P = .02) and 12 months (2.7 vs 3.1, P = .04).
• Total standard drinks in the past three months were reduced at six months (176 vs 216, P = .04).
• No significant differences were observed in drinks per drinking day, abstinence, or healthcare use.

Conclusions:

• A brief motivational intervention, utilizing minimal clinician time and counselor support, effectively reduced the frequency of alcohol consumption in a primary care population.
• The intervention demonstrated modest but statistically significant reductions in drinking frequency, particularly in drinking days per week.
• Future research should aim to enhance and sustain the effects of such brief interventions.
