Partners in prevention: the role of health systems in the prevention of youth violence in post-conflict Northern Ireland

Interpersonal violence is a wicked and complex issue with youth disproportionately affected. Its effects are multifaceted, placing an additional burden across systems. Despite this, there continues to be an exclusive focus on police recorded crime data in the context of post-conflict Northern Ireland. Given the enduring issue around police legitimacy, it is likely that police-related crime data are limited in its capacity to estimate incidences and trends of youth violence. Leveraging insights from other sources of data can add significant value in the prevention of youth violence. For example, there is significant utility in the use of health-related data in the prevention of higher-harm violence; however, in the context of Northern Ireland this has been under-evaluated. This retrospective cohort study sought to illustrate what could be gleaned using a novel approach to Emergency Department (ED) data. Routinely collected data captured from youth aged 12–25 attending an ED trauma centre for violence-related injuries between August 2020 and August 2021 were collated, coded and analysed. We found that young men were most likely to present to ED with violence-related injuries; incidences were temporally clustered across several months of the year (i.e. Summer); and younger aged youth were at greater risk of violence-related injuries during the afternoon and early evening. These findings illustrate the utility of health data for violence prevention and the potential for integrating administrative datasets in the design of prevention policy. Limitations and implications for practice are discussed.
