WHO VIP Webinar THE CARDIFF MODEL FOR VIOLENCE PREVENTION Jonathan Shepherd Professor of Oral & Maxillofacial SurgeryDirector, Violence Research Group
RECORDING OF VIOLENCE BY THE POLICE AND IN EDs • Police recording varies by victim age and gender and violence location • Only 23% of people injured in violence who attend EDs are known to the police • Crime surveys in UK, Sweden and US demonstrate similar police recording rates
LOW POLICE ACSERTAINMENT OF SERIOUS VIOLENCE IS AN INTERNATIONAL PROBLEM 1403 (100%) victims 869 (62%) victims 327 (23%) victims 207 (15%) victims ODENSE UNIVERSITY HOSPITAL POLICE (Faergemann 2006)
Police recording is not closely related to injury severity • 13% of firearm violence recorded in Atlanta EDs was not recorded by police (Kellerman el al 2003)
REASONS WHY VIOLENCE IS NOT KNOWN TO THE POLICE • Non reporting reflects fear of reprisals, inability of injured people to identify assailant(s), unwillingness to have own conduct scrutinised and need for emergency treatment • Non recording of reported incidents
INJURY-BASED APPROACH: National / Regional violence measurement Emergency Department data Local surveillance/prevention
INDEPENDENT NATIONAL CORRELATES WITH ED TREATMENT AFTER VIOLENCE • Unemployment / Deprivation • Ethnic minority population • Alcohol expenditure • Alcohol price • Season
Statutory in UK: 373 crime reduction partnerships Crime and Disorder Act 1998 Police Reform Act 2002 PROTOTYPE CRIME REDUCTION PARTNERSHIP: CARDIFF VIOLENCE PREVENTION GROUP
SUSTAINABLE ED DATA COLLECTION AND USE Step One: 24 hour electronic data collection (precise violence location, time and weapon) by ED clerical staff when patients first attend Step Two: Monthly anonymisation and data sharing by hospital IT staff with crime analyst Step Three: Monthly combination of police and ED data by analyst Step Four: Summary of violence times, locations and weapons – for police deployment and license regulation Step Five: Continuous implementation and updating of prevention action plan
VIOLENCE PREVENTION Licensed premises traffic light scheme. Effective policing, situational and environmental interventions: • Targeted street patrols, CCTV, redeployment of police from suburbs into city centre at night • Plastic glassware, fast food outlet relocation • Pedestrianisation of entertainment streets • Identification of people injured in domestic violence
Case Studies • ED information identified a source of blunt weapons – a construction site next to a night club with skips containing bricks, concrete blocks and pieces of wood. Skips were secured and violence fell • ED information identified series of attacks on cyclists in a neighbourhood. Police targeted this area and violence fell • ED information identified several violence hotspot pubs/night clubs. Alcohol licence conditions imposed and some licences revoked. Violence fell Source: Dines 2011
CHANGES IN VIOLENCE RELATED HOSPITAL ADMISSIONS AND WOUNDINGS RECORDED BY THE POLICE • Hospital Admissions: down 24/year/100,000 population in Cardiff up 36/year/100,000 in comparison cities • Woundings recorded by police: up 336/year/100,000 population in Cardiff up 720/year/100,000 in comparison cities Florence et al BMJ 2011
ANNUAL COSTS AND BENEFITS • Annual cost of Intervention: £5,176 • Annual cost of recorded woundings avoided (benefits): £789k • Cost/Benefit Ratio - total costs avoided = 1:152 • Cost/Benefit Ratio - criminal justice costs avoided = 1:31 Analyses carried out by Curtis Florence at the US Centres for Disease prevention and Control, Atlanta, using 2008 costs
The Cardiff Model works by facilitating earlier and more frequent police intervention through the use of information from EDs – and keeps people out of hospital and out of prison
Targeted policing prevents violence Eg Braga 2007 and has violence prevention diffusion effects Eg Weisburd et al 2007
EFFECT OF CCTV ON POLICE VIOLENCE DETECTION 12 CCTV towns (n=5) 10 8 6 Control towns (n=5) Percentage change 4 2 0 -2 -4 2 years after CCTV 2 years before CCTV Sivarajasingam et al, 2003
EFFECT OF CCTV ON ASSAULTED ATTENDANCE Control towns Control towns CCTV towns CCTV towns
OTHER MECHANISMS OF EFFECTIVENESS • Identification and support of people injured in domestic violence – prevents repeat victimisation • Identification of weapon trends – informs weapon-orientated prevention strategies • Identifies violence hotspots, park locations and walkways for example, which can be targeted by city government officials
PREVENTION INGREDIENTS • Emergency physician/surgeon contributions to local community safety partnerships: advocacy from health makes a difference
PITFALLS • Lack of leadership and management • Low data quality • Poor analysis • Information not used • Purpose of information not explained • Too much strategy, not enough tactics • Complicating a simple process
