We investigated the effect of the new zero-tolerance drinking and driving law (Law 12760) on hospital admissions due to road traffic accidents in Brazil by using interrupted time series from 2008 to 2019. We used ICD-10 codes for land transport accidents (V00-V89). The hospitalization rate was calculated per 100,000 inhabitants. The sources were the Hospital Information System and the Brazilian Institute for Geography and Statistics. For Brazil, the hospitalization rate decreased by 0.400841 (p=0.052; 95% CI -0.8060128 to -0.0043307) in the first month of the intervention (December 2012), followed by a significant change in the hospitalization trend. Compared to the period prior to the intervention, the monthly trend was reduced by 0.048215 (p<0.01; 95% CI 0.0614524 to 0.0349775) in the post period. These results stand in agreement with subgroup analyses for the Brazilian regions, although North and Northeast regions did not immediately reduce hospitalization rates (level change). Our results suggested that 436,581 hospitalizations for land transport accidents were averted by the new zero-tolerance drinking and driving law from Dec. 2012 to Dec. 2019 in Brazil.
