The Cardiff Model of data sharing for violence prevention is premised on the idea that the majority of injury cases presenting at health facilities as a result of interpersonal violence will not be reported to the police. The aim of this study was to determine the concordance between violent crimes reported to the police with violence-related injuries presenting at health facilities in Cape Town, South Africa.
We conducted a retrospective analysis of secondary cross-sectional health and police data, from three health facilities and three police stations in the community of Khayelitsha, Cape Town. 781 cases of injuries arising from interpersonal violence seen at health facilities were compared with 739 violence-related crimes reported at police stations over five separate week-long sampling periods from 2013 to 2015. Personal identifiers, name and surname, were used to match cases.
Of the 708 cases presenting at health facilities, 104 (14.7%) were matched with police records. The addition of non-reported cases of violence-related injuries from the health dataset to the police-reported crime statistics resulted in an 81.7% increase in potential total violent crimes over the reporting period. Compared with incidents reported to the police, those not reported were more likely to involve male patients (difference: +47.0%; p<0.001) and sharp object injuries (difference: +24.7%; p<0.001). Push/kick/punch injuries were more frequent among reporting than non-reporting patients (difference: +17.5%; p<0.001).
These findings suggest that the majority of injuries arising from interpersonal violence presenting at health facilities in Khayelitsha are not reported to the police. A data-sharing model between health services and the police should be implemented to inform violence surveillance and reduction.
卡迪夫预防暴力数据共享模式基于这样一种理念，即大多数因人际暴力而在医疗机构就诊的伤害案例不会向警方报告。本研究旨在确定南非开普敦哈耶利特沙地区向警方报告的暴力犯罪与在医疗机构就诊的与暴力相关的伤害之间的一致性。
我们对来自开普敦哈耶利特沙地区三个医疗机构和三个警察局的二次横断面卫生和警察数据进行了回顾性分析。将 781 例因人际暴力而在医疗机构就诊的伤害病例与 2013 年至 2015 年五个单独为期一周的采样期间在警察局报告的 739 例与暴力相关的犯罪进行了比较。使用个人标识符、姓名和姓氏来匹配病例。
在就诊于医疗机构的 708 例病例中，有 104 例（14.7%）与警方记录相匹配。将卫生数据集来自报告的暴力相关伤害案件添加到警方报告的犯罪统计数据中，导致报告期间潜在暴力犯罪总数增加了 81.7%。与向警方报告的事件相比，未报告的事件更有可能涉及男性患者（差异：+47.0%；p<0.001）和锐器伤（差异：+24.7%；p<0.001）。推/踢/拳击伤在报告病例中比未报告病例更常见（差异：+17.5%；p<0.001）。
这些发现表明，在哈耶利特沙的医疗机构就诊的因人际暴力而导致的大多数伤害都没有向警方报告。应在卫生服务机构和警方之间实施数据共享模型，以提供暴力监测和减少的信息。
