BACKGROUND
Brief interventions (BI) have been shown to reduce alcohol use and improve outcomes in Hazardous and Harmful (HH) drinkers but evidence to support their use in emergency department (ED) patients is limited. The use of research assessments in studies of BI may contribute to uncertainty about their effectiveness.
METHODS
We randomized 889 adult ED patients with HH drinking. A total of 740 received 1) an emergency practitioner (EP)-performed Brief Negotiation Interview (BNI, n=297), 2) BNI with a 1-month follow-up telephone booster (BNI with Booster), (n=295), or 3) standard care (SC, n=148). We also included a standard care with no assessments (SC-NA, n=149) group to examine the impact of assessments on drinking outcomes. Primary outcomes analyzed using mixed models procedures included past 7-day alcohol consumption and 28-day binge episodes at 6 and 12 months collected by Interactive Voice Response. Secondary outcomes included negative health behaviors and consequences collected by phone surveys.
RESULTS
The reduction in mean number of drinks in the past 7 days from baseline to 6 and 12 months was significantly greater in BNI with Booster: from 20.4 (95% confidence interval [CI], 18.8-22.0) to 11.6 (95% CI, 9.7-13.5) to 13.0 (95% CI, 10.5-15.5) and BNI: from 19.8 (95% CI, 18.3-21.4) to 12.7 (95% CI, 10.8-14.6), to 14.3 (95% CI, 11.9-16.8), than in SC: from 20.9 (95% CI, 18.7-23.2) to 14.2 (95% CI, 11.2-17.1), to 17.6 (95% CI, 14.1-21.2). The reduction in 28-day binge episodes was also greater in BNI with Booster: from 7.5 (95% CI, 6.8-8.2) to 4.4 (95% CI, 3.6-5.2) to 4.7 (95% CI, 3.9-5.6) and in BNI: from 7.2 (95% CI, 6.5-7.9) to 4.8 (95% CI, 4.0-5.6), to 5.1 (95% CI, 4.2-5.9), than in SC: from 7.2 (95% CI, 6.2-8.2) to 5.7 (95% CI, 4.5-6.9), to 5.8 (95% CI, 4.6-7.0). BNI with Booster offered no significant benefit over BNI. There were no differences in drinking outcomes between the SC and SC-NA groups. The reductions in rates of driving after drinking ≥ 3 drinks from baseline to 12 months were greater in the BNI (38% to 29%) and BNI with Booster (39% to 31%) groups than in the SC group (43% to 42%).
CONCLUSIONS
EP-performed brief interventions can reduce alcohol consumption and episodes of driving after drinking in HH drinkers. These results support the use of brief interventions in ED settings.
