Linking drinking to injury--causal attribution of injury to alcohol intake among patients in a Swedish emergency room.

This study analysed the drinking patterns and motivation to change drinking behaviours among injury patients who acknowledged alcohol as a factor in their injuries. A cross-sectional study was conducted over 18 months at a Swedish emergency department. A total of 1930 injury patients aged 18 - 70 years were enrolled in the study (76.8% completion rate). Of those who reported drinking, 10% acknowledged alcohol as a factor in their injury. A patient was more likely to report a causal attribution of the injury to alcohol the higher the weekly intake and the higher the frequency of heavy episodic drinking. The motivation to change variables showed a similar pattern of increased likelihood of attributing a causal link of alcohol and injury with increasing discontent with drinking behaviours and increasing desire to change drinking behaviours. The findings suggest that the ability to measure causal attribution of alcohol to injuries could be a promising tool to help patients explore the association between their injuries and alcohol use and motivate patients to modify drinking behaviours in order to avoid future injuries.
