RESUMEN
Objective: 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. Methods: 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. Results: 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]: 0.59â0.90; p = 0.003). The relative risk for phase 2 compared to phase 1 was 0.92 (95% CI: 0.76â1.12; p = 0.418). Conclusion: 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.
RESUMEN
Objective: Violence is a major preventable problem in emergency departments (EDs), and validated screening tools are needed to identify potentially violent patients. We aimed to test the utility of the Aggressive Behavior Risk Assessment Tool (ABRAT) for screening patients in the ED. Methods: A prospective cohort study was conducted among adult and pediatric patients aged ≥10 years visiting 3 emergency departments in Michigan between May 1, 2021, and June 30, 2021. Triage nurses completed the 16-item checklist using electronic health records (EHRs), and the occurrence of violent incidents were collected before ED disposition. A multivariate logistic regression model was applied to select a parsimonious set of items. Results: Among 10,554 patients, 127 had ≥1 violent incidents (1.2%). The regression model resulted in a 7-item ABRAT for EDs, including history of aggression and mental illness and reason for visit, as well as 4 violent behavior indicators. Receiver operating characteristics analysis showed that the area under the curve was 0.91 (95% confidence interval [CI], 0.87-0.95), with a sensitivity of 84.3% (95% CI, 76.5%-89.9%) and specificity of 95.3% (95% CI, 94.8%-95.7%) at the optimal cutoff score of 1. An alternative cutoff score of 4 for identifying patients at high risk for violence had a sensitivity and specificity of 70.1% and 98.9%, respectively. Conclusion: The ABRAT for EDs appears to be a simple yet comprehensive checklist with a high sensitivity and specificity for identifying potentially violent patients in EDs. The availability of such a screening checklist in the EHR may allow rapid identification of high-risk patients and implementation of focused mitigation measures to protect emergency staff and patients.
RESUMEN
The purpose of this article is to describe the impact of an evidence-based alarm management strategy on patient safety. An alarm management program reduced alarms up to 30%. Evaluation of patients on continuous cardiac monitoring showed a 3.5% decrease in census. This alarm management strategy has the potential to save $136 500 and 841 hours of registered nurses' time per year. No patient harm occurred during the 2-year project.
