Commentary on ‘The research translation problem: alcohol screening and brief intervention in primary care – real world evidence supports theory’

The paper by McCormick et al. (2010) provides real-world examples of best practice for implementing alcohol screening and brief intervention (SBI) in primary care. We commend the authors for that and also wish to highlight the additional challenges involved in implementing SBI in primary care among vulnerable populations, especially problem drug users.
