The objective of this study was to measure the efficacy of protection orders (POs) in reducing assault and injury-related outcomes using a matched comparison group and tracking outcomes over time. This study was a retrospective review of police, emergency department, family court, and prosecutor administrative records for a cohort of police-involved female IPV victims; all events over a 4-year study period were abstracted. Victims who obtained POs were compared with a propensity-score-based match group without POs over three time periods: Before, During, and After the issuance of a PO. Having a PO in place was associated with significantly more calls to police for nonassaultive incidents and more police charging requests that were of multiple-count and felony-level. Comparing outcomes, PO victims had police incident rates that were more than double the matched group prior to the PO but dropped to the level of the matched group during and after the order. ED visits dropped over time for both groups. This study confirmed the protective effect of POs, which are associated with reduced police incidents and emergency department visits both during and after the order and reduced police incidents compared with a matched comparison group.
本研究旨在通过匹配对照组并随时间跟踪结果来衡量保护令 (PO) 在减少攻击和伤害相关结果方面的效果。这项研究是对警察、急诊部、家庭法庭和检察官行政记录的一项回顾性分析，针对的是一组涉及警察的女性 IPV 受害者；在 4 年的研究期间，所有事件都被摘录下来。获得保护令的受害者与未获得保护令的倾向评分匹配组在三个时间段进行了比较：在发出保护令之前、期间和之后。拥有保护令与更多非攻击性行为的报警电话和更多多计数和重罪级别的警察指控请求相关。比较结果显示，在获得保护令之前，PO 受害者的警察事件发生率是匹配组的两倍多，但在保护令期间和之后降至匹配组的水平。ED 就诊次数随时间减少。本研究证实了保护令的保护作用，这与在保护令期间和之后减少警察事件和急诊就诊次数以及与匹配对照组相比减少警察事件有关。
