ObjectiveTo examine emergency department (ED) data sharing via a local injury surveillance system and assess its contribution to the prevention of violence and alcohol-related harms.Methods6-year (2004-2010) exploratory study analysing injury attendances to one ED in the North West of England using descriptive and trend analyses.ResultsOver the 6-year period, there were 242,796 ED injury attendances, including 21,683 for intentional injuries. Compared with unintentional injury patients, intentional injury patients were more likely to be men, aged 18-34 years, live in the most deprived communities, have attended the ED at night/weekends, have been injured in a public place and have consumed alcohol prior to the injury. Detailed data collected on alcohol and violence-related ED attendances were shared with local partners to monitor local trends and inform prevention activity including targeted policing and licensing enforcement. Over the 6-year period, intentional ED injury attendances decreased by 35.6% and alcohol-related assault attendances decreased by 30.3%.ConclusionsThe collection of additional ED data on assault details and alcohol use prior to injury, and its integration into multi-agency policy and practice, played an important role in driving local violence prevention activity. Further research is needed to assess the direct contribution ED data sharing makes to reductions in violence.
