Changing epidemiology of assault victims in an emergency department participating in information sharing with police: a time series analysis.

Introduction: Violent injury places a large burden on the NHS. We had implemented information sharing in our ED in 2007 and aimed to see which patient groups were most affected by information sharing, as this would provide clues as to how this complex intervention works.

Methods: Retrospective time series study of all the assault victims presenting for ED care between 2005 and 2014 at a single ED in England.

External validation of the Cardiff model of information sharing to reduce community violence: natural experiment.

Background: Community violence is a substantial problem for the NHS. Information sharing of emergency department data with community safety partnerships (CSP) has been associated with substantial reductions in assault attendances in emergency departments supported by academic institutions. We sought to validate these findings in a setting not supported by a public health or academic structure.
