Screening for substance misuse and conducting brief interventions to reduce harm from drug, alcohol, or cigarette use

Overview

Systematic, non-judgemental substance misuse screening (using validated tools) followed by brief intervention for those identified at risk is an evidence-based approach for reducing substance-related harm at the population level, applicable across routine general and specialist clinical practice, not only within dedicated addiction services
Recommended as part of routine health assessment given the high population prevalence of at-risk substance use and the evidence that even brief, low-intensity intervention can meaningfully reduce harm in patients not requiring intensive specialist treatment

Brief intervention (structured feedback on screening results, advice, and goal-setting, typically delivered in a single short consultation) works by raising awareness and providing a structured opportunity for reflection and behaviour change at a stage before dependence has fully developed - explaining why it is most effective for at-risk/hazardous use rather than established severe dependence, which typically requires more intensive treatment

Validated brief screening tools (e.g. AUDIT-C for alcohol, and equivalent tools for other substances) allow rapid, structured identification in routine consultations without requiring extensive time investment
Screening should be routine and universal (not only applied when substance use is already suspected from other clues), given both under-disclosure without direct enquiry and the value of identifying at-risk use before it becomes clinically obvious

Brief intervention (FRAMES-style structured feedback - Feedback, Responsibility, Advice, Menu of options, Empathy, Self-efficacy) for patients identified with at-risk/hazardous use on screening
Referral to specialist addiction services for patients with more severe use/dependence identified on screening, where brief intervention alone is unlikely to be sufficient
Harm reduction information/resources (see ) as an additional component regardless of readiness for full behaviour change

SBIRT (Screening, Brief Intervention, Referral to Treatment) as a structured framework, FRAMES brief intervention components, universal vs targeted screening approach, brief intervention efficacy specifically for at-risk (not severely dependent) use

Brief intervention is most effective for at-risk or hazardous substance use identified through screening, before dependence has fully developed - it is not intended as a substitute for specialist treatment in patients with established severe substance use disorder, who require referral to more intensive treatment; screening should therefore also identify which category a patient falls into to direct them to the appropriately matched level of intervention
