The study investigated the feasibility of implementing the Cardiff Model. The Cardiff Model is a unique violence surveillance system and intervention that involves data sharing and violence prevention planning between law enforcement and the medical field. Anonymized data on assaults from emergency and police departments (EDs; PDs) are combined to detail assault incidents and "hotspots." Data are discussed by a multidisciplinary consortium, which develops and implements a data-informed violence prevention action plan that includes behavioral, environmental, and policy changes to impact violence. Model actions led to decreases in injurious assaults and this model is now statutory in the United Kingdom. The Cardiff Model has never been translated to the U.S. and would require an investigation within our health care system and in different geographical and population contexts. This study investigated the feasibility of essential Cardiff Model Components in order to refine study procedures and situate this community to request further funds for full model implementation. As part of this study, researchers collected a number of feasibility measures from ED and study staff to evaluate the feasibility of translating included model components. Geospatial and statistical analyses investigated the added benefit of the combined ED, PD and Emergency Medical Services (EMS) data. The study contains 1 SPSS data files (CHW Data_1.1.15 to 7.31.16.sav (n=748; 14 variables)), 1 STATA data file (nurse survey data.dta (n=43; 26 variables)), a text document (Nurse Survey_Qualitative data.txt), and 1 excel file (CHW Incidents_Block level data only.xlsx).
