Acute and usual drinking among emergency trauma patients: A study on alcohol consumption and injury patterns

To investigate the relationship between usual and acute alcohol consumption among injured patients and, when combined, how they covary with other injury attributes. Data from a randomised sample of 486 injured patients interviewed in an emergency department (Lausanne University Hospital, Switzerland) were analysed using the x2 test for independence and cluster analysis. Acute alcohol consumption (24.7%) was associated with usual drinking and particularly with high volumes of consumption. Six injury clusters were identified. Over-representations of acute consumption were found in a cluster typical of injuries sustained through interpersonal violence and in another formed by miscellaneous circumstances. A third cluster, typical of sports injuries, was linked to a group of frequent heavy episodic drinkers (without acute consumption) Among injured patients, acute alcohol consumption is common and associated with usual drinking. Acute and/or usual consumption form part of some, but not all, injury clusters.
