Alcohol and injury: a comparison of emergency room populations in two Canadian provinces

The few comparative emergency room (ER) studies reported have found alcohol's role in injury occurrence to vary and suggest that regional and cultural differences in drinking patterns may account, in part, for this variation. To further this research, a probability sample of 1708 ER patients was interviewed regarding the role of alcohol in the event, usual drinking patterns, and alcohol-related problems and a urine sample was obtained to estimate blood alcohol concentration (BAC). The sample was from ERs in two Canadian provinces with distinctly different cultures: primarily English-speaking Alberta and French-speaking Quebec. While differences in demographic and drinking characteristics between injured and noninjured in both the Alberta and Quebec ERs were similar to those in other ER studies, the injured in the Alberta ER were more likely to be positive for estimated BAC; to have higher BAC levels; to report drinking prior to the event; and, among those reporting drinking, to have consumed a larger number of drinks and to report feeling drunk at the time of injury compared to those in Quebec. These differences may be associated with cultural differences in typical drinking patterns, with higher rates of abstinence reported in the Alberta ER, but also with higher rates of heavy drinking and alcohol-related problems, while those in the Quebec ER were more likely to report consuming smaller quantities with greater frequency (typical of wine-drinking cultures). Additional research is needed to explicate further alcohol's role in injury occurrence for planning effective prevention strategies that are both culturally relevant and specific.
