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).
description: The goals of this feasibility study were to 1) begin to translate the model to an urban U.S. city, 2) expand upon the model to include data from Emergency Medical Services (EMS), 3) measure the benefits of combining data on police involvement, ED visits, and EMS calls for estimates of community assault rates, 4) recruit stakeholders who are interested in participating in the model's community consortium intervention, and 5) to describe the steps for model adoption into other communities.
description: The study includes two main sections: 1) Record review: secondary analyses of patient chart data and calls for service for police and EMS: The secondary analysis utilized data downloaded from EPIC, including relevant patient chart information. Data were requested periodically from the time violence-related questions were implemented until 12/31/2016. Clinical records were obtained by using the Cohort Discovery Tool of the MCW Clinical Data Warehouse, by searching using inclusion criteria. Geocoding from Police and EMS Records: The West Allis and Milwaukee Police Departments and the Milwaukee County EMS database provided the study with de-identified data on calls for service related to violence and assaults from their electronic management system. Data on address/locations of injury occurrence from emergency rooms, police departments, and EMS were geocoded to identify assault hotspots or clusters. 2) The Feasibility Study involved longitudinal data collection of survey data from hospital staff. Feasibility criteria were defined as acceptability, demand, implementation, practicality, adaption, integration, expansion, and limited efficacy.Survey data was collected from hospital nurses using Survey Monkey. Questions featured a 5 point Likert scale as well as 2 opened ended questions.
description: The ED patient data contains 14 variables: gender, race, ethnicity, financial class, age, by whom the patient was escorted, patient means of arrival to the ED, were perpetrators under the age of 18, date of injury, time of injury, what state the injury occurred in, what city the injury occurred in, type of injury, weapon involved. The nurse survey data contains 26 variables: 24 variables of Likert scale responses to questions regarding their experience and satisfaction with violence-related questioning, other variables include years employed at the hospital, age, and 2 open ended questions. Responses to open ended questions from the Nurse Survey are documented in the Qualitative data text file. The block level incidents in the Excel file contain XY coordinates of mapped incidents reported in the emergency department data.
description: none
description: Response Rates: Nurse Survey: 55.8% CHW Data (ED Patients):98%
description: Presence of Common Scales: Several Likert-type scales were used.
description: Patients that were sampled include all patients presenting to the Children's Hospital of Wisconsin Emergency Department that indicated they had sustained an injury as the result of an assault. Nurses that were sampled include all nurses that were employed with the Children's Hospital of Wisconsin Emergency Department during the time of Nurse Survey administration.
