Abstract

methodology. 5 Combining hospital and police data may allow for a more complete picture of violence.Limitations of the study include that findings are generated from a single city.Furthermore, this study focused on violence occurring in public places only and does not provide information on reporting by injury severity.Third, this study does not include comparison with minor criminal charges such as "simple assault"; although not readily used as a criminal charge for violent injuries necessitating ED treatment in this study's jurisdictions, use of criminal charges can vary across police jurisdictions.Last, beyond the potential of misreporting by patients, only approximately 40% of violent incidents contained enough information to be mapped.Nonetheless, we hypothesize that patients declining to provide detailed information to nurses have specific reasons for nondisclosure 6 and would therefore also be unlikely to provide such information to police.This suggests that the number of incidents unreported to police may be even higher than we detected.In summary, these findings emphasize the potential of ED and police data to provide a complementary and comprehensive understanding of violent injury resulting in significant morbidity.This study provides new support for the United States on the value of cross-sectoral partnerships,
