Dynamic cohort study based on registry data from 1818 patients included in a screening and brief intervention program for alcohol and illicit drug use for hospitalized trauma patients. Three subcohorts emerged from the data analysis: patients who screened negative, those who screened positive and were offered brief intervention, and those who screened positive and were not offered brief intervention. Follow-up lasted from 10 to 52 months. Trauma-free survival, adjusted hazard rate ratios (aHRR) and adjusted incidence rate ratios (aIRR) were calculated, and complier average causal effect (CACE) analysis was used. We found a higher cumulative risk of trauma recidivism in the subcohort who screened positive. In this subcohort, an aHRR of 0.63 (95% CI: 0.41-0.95) was obtained for the group offered brief intervention compared to the group not offered intervention. CACE analysis yielded an estimated 52% reduction in trauma recidivism associated with the brief intervention. The brief intervention offered during hospitalization in trauma patients positive for alcohol and/or illicit drug use can halve the incidence of trauma recidivism.enAttribution 4.0 Internationalhttp://creativecommons.org/licenses/by/4.0/AdultAlcohol DrinkingCohort StudiesFemaleFollow-Up StudiesHospitalizationHumansIllicit DrugsKaplan-Meier EstimateMaleMiddle AgedRetrospective StudiesSeverity of Illness IndexSpainTrauma CentersWounds and Injuriesresearch article28813444open access10.1371/journal.pone.01824411932-6203PMC5559089https://journals.plos.org/plosone/article/file?id=10.1371/journal.pone.0182441&type=printablehttps://www.ncbi.nlm.nih.gov/pmc/articles/PMC5559089/pdf
