Alcohol use disorder (AUD) screening is important but focused training with using AUDIT‐10 with counselling/mental health (MH) referral may be needed. We aimed to compare the effect of training on AUD screening/intervention in hepatology clinics in pre vs post‐training phases of a quality‐improvement initiative. Pre‐training encounters were evaluated for inquiry into AUD, AUDIT‐10 and MH referrals. Dedicated AUD‐related training was provided to hepatology providers and analyses repeated post‐training. Pre‐training (n = 378) and post‐training patients(n = 318) had similar demographics and disease characteristics. Post‐training there was higher inquiry about alcohol(92% vs 80%, P < .0001), counselling (82% vs 68%, P < .0001). This led to higher diagnosis of drinkers (49% vs 31%, P < .0001) of whom higher proportion had AUDIT‐10 administered(91% vs 34%, P < .0001) and referred to MH(29% vs 8%, P < .0001). On regression presumed alcohol‐related aetiology, younger age and post‐training period were associated with AUDIT‐10 administration. AUD‐focused training significantly improves rates of screening and MH referral for problem drinking in a hepatology clinic population.
