To investigate whether sharing and linking routinely collected violence data across health and criminal justice systems can provide a more comprehensive understanding of violence, establish patterns of under-reporting and better inform the development, implementation and evaluation of violence prevention initiatives.
Police violence with injury (VWI) crimed data and emergency department (ED) assault attendee data for South Wales were collected between 1 April 2014 and 31 March 2016 to examine the rates and patterns of VWI. Person identifiable data (PID) were cross-referenced to establish if certain victims or events were less likely to be reported to criminal justice services.
A total of 18 316 police crimed VWI victims and 10 260 individual ED attendances with an assault-related injury were considered. The majority of ED assault attendances (59.0%) were unknown to police. The key demographic identified as under-reporting to police were young males aged 18-34 years, while a significant amount of non-reported assaults involved a stranger. The combined monthly age-standardised rates were recalculated and on average were 74.7 (95% CI 72.1 to 77.2) and 66.1 (95% CI 64.0 to 68.2) per 100 000 population for males and females, respectively. Consideration of the additional ED cases resulted in a 35.3% and 18.1% increase on the original police totals for male and female VWI victims.
This study identified that violence is currently undermeasured, demonstrated the importance of continued sharing of routinely collected ED data and highlighted the benefits of using PID from a number of services in a linked way to provide a more comprehensive picture of violence.
调查跨卫生和刑事司法系统共享和关联常规收集的暴力数据，是否能更全面地了解暴力情况，确定漏报模式，并为暴力预防举措的制定、实施和评估提供更充分的信息。
收集2014年4月1日至2016年3月31日期间南威尔士警方记录的有伤害的暴力犯罪（VWI）数据和急诊科（ED）的袭击伤者数据，以研究VWI的发生率和模式。对可识别个人的数据（PID）进行交叉比对，以确定某些受害者或事件向刑事司法服务机构报告的可能性是否较低。
共纳入18316名警方记录的VWI受害者以及10260名因袭击相关伤害到急诊科就诊的个体。警方对大多数急诊科袭击伤者（59.0%）并不知晓。确定向警方漏报的关键人群为18 - 34岁的年轻男性，同时大量未报告的袭击涉及陌生人。重新计算了合并后的每月年龄标准化发生率，男性和女性每10万人口的平均发生率分别为74.7（95%CI 72.1至77.2）和66.1（95%CI 64.0至68.2）。考虑到额外的急诊科病例，男性和女性VWI受害者的原始警方统计总数分别增加了35.3%和18.1%。
本研究发现目前对暴力的衡量不足，证明了持续共享常规收集的急诊科数据的重要性，并强调了以关联方式使用多个服务机构的PID以更全面了解暴力情况的益处。
