■针对潜在暴力患者的积极缓解措施可以预防急诊科(ED)中的患者暴力。我们的目的是在经过验证的风险评估工具的指导下评估两种干预措施的效果。
■一项前瞻性干预研究是在密歇根州两次就诊的≥10年的患者中进行的,美国,从2022年10月到2023年8月。在分诊期间,ED护士完成了ED的攻击行为风险评估工具(ABRAT-ED),以识别高危患者。基线观察期后,对高危患者逐步实施干预措施:第一阶段为标牌张贴,第二阶段为主动行为应急响应小组(BERT)加入标牌张贴.在ED处置之前,任何暴力事件及其严重性都有记录。研究完成后,对数据进行回顾性检索。
■在77,424名可评估患者中,546例暴力事件≥1例。暴力事件发生率为0.93%,0.68%,基线为0.62%,阶段1和阶段2。与基线相比,1期暴力事件的相对风险为0.73(95%置信区间[CI]:0.59-0.90;p=0.003)。与第1阶段相比,第2阶段的相对风险为0.92(95%CI:0.76-1.12;p=0.418)。
■对于ABRAT-ED识别的高危患者,使用标牌张贴作为持续的视觉提示似乎可以有效降低总体暴力事件发生率。然而,在标牌张贴中添加主动BERThuddle显示,与单独张贴标牌相比,暴力事件发生率没有显着降低。
UNASSIGNED: Patient violence in emergency departments (EDs) may be prevented with proactive mitigation measures targeting potentially violent patients. We aimed to evaluate the effects of two interventions guided by a validated risk-assessment tool.
UNASSIGNED: A prospective interventional study was conducted among patients ≥10 years who visited two EDs in Michigan, USA, from October 2022 to August 2023. During triage, the ED nurses completed the Aggressive Behavior Risk Assessment Tool for EDs (ABRAT-ED) to identify high-risk patients. Following the baseline observational period, interventions were implemented stepwise for the high-risk patients: phase 1 period with signage posting and phase 2 period with a proactive Behavioral Emergency Response Team (
BERT) huddle added to the signage posting. Before ED disposition, any violent events and their severities were documented. The data were retrieved retrospectively after the study was completed.
UNASSIGNED: Of 77,424 evaluable patients, 546 had ≥1 violent event. The violent event rates were 0.93%, 0.68%, and 0.62% for baseline, phase 1, and phase 2, respectively. The relative risk of violent events for phase 1 compared to the baseline was 0.73 (95% confidence interval [CI]: 0.59‒0.90; p = 0.003). The relative risk for phase 2 compared to phase 1 was 0.92 (95% CI: 0.76‒1.12; p = 0.418).
UNASSIGNED: The use of signage posting as a persistent visual cue for high-risk patients identified by ABRAT-ED appears to be effective in reducing the overall violent event rates. However, adding proactive
BERT huddle to signage posting showed no significant reduction in the violent event rates compared to signage posting alone.
