A RCT of three training and support strategies to encourage implementationof screening and brief alcohol intervention by general practitioners

Background. Providing doctors with new research findings or clinical guidel ines is rarely sufficient to promote changes in clinical practice. An imple mentation strategy is required to provide clinicians with the skills and en couragement needed to alter established routines. Aim. To evaluate the effectiveness and cost-effectiveness of different trai ning and support strategies in promoting implementation of screening and br ief alcohol intervention (SBI) by general practitioners (GPs). Method. Subjects were 128 GPs, one per practice, from the former Northern a nd Yorkshire Regional Health Authority who agreed to use the 'Drink-Less' S BI programme in an earlier dissemination trial. GPs were stratified by prev ious marketing conditions and randomly allocated to three intensities of tr aining and support: controls (n = 43) received the programme with written g uidelines only, trained GPs (n = 43) received the programme plus practice-b ased training in programme usage, trained and supported GPs (n = 42) receiv ed the programme plus practice-based training and a support telephone call every two weeks. GPs were requested to use The programme for three months. Outcome measures included proportions of GPs implementing the programme and numbers of patients screened and intervened with. Results: Seventy-three (57%) GPs implemented the programme and screened 11 007 patients for risk drinking. Trained and supported GPs were significantl y more likely to implement the programme (71%) than controls (44%) or train ed GPs (56%); they also screened, and intervened with, significantly more p atients. Costs per patient screened were: trained and supported GPs, pound 9.05; trained GPs, pound 1.08; and controls, pound 1.47. Costs per patient intervened with were: trained and supported GPs, pound 5.43; trained GPs, p ound 6.02 and controls, pound 8.19. Conclusion. Practice-based training plus support telephone calls was the mo st effective and cost-effective strategy to encourage implementation of SBI by GPs.
