Aim: To evaluate the feasibility, effectiveness and cost-effectiveness of opportunistic screening and stepped care intervention in primary care.

Design: Pragmatic prospective randomised controlled trial.

Setting: Six primary care practices in South Wales.

Participants: 1794 male primary care attendees were screened using the Alcohol Use Identification Test (AUDIT). 112 who scored 8 or more on the AUDIT and who consented to enter the study were randomised.

Interventions: Control group: 5 min. minimal intervention delivered by a practice nurse. Intervention group: stepped care intervention consisting of three successive steps: 1. a single session of Behaviour Change Counselling delivered by a practice nurse, 2. 4 sessions x 50 min Motivational Enhancement Therapy delivered by a trained alcohol counsellor, and 3. referral to a community alcohol treatment agency.

Measurements: Percent days abstinent using TLFB180, Motivation using the Readiness to Change Questionnaire, Severity of Alcohol Dependence Questionnaire, Alcohol Problems Questionnaire, Self-efficacy using the Situational Confidence Questionnaire, Quality of Life using SF12, Health utility using EQ5D and service utilisation.

Findings and conclusions: Stepped care was feasible to implement in this setting. Both groups reduced alcohol consumption six months after randomisation with a greater, although not significant, improvement for the stepped care intervention. Motivation to change was greater following stepped care intervention. Stepped care intervention resulted in greater cost savings compared to minimal intervention.
