Prevalence and correlates of knife-related victimization: Insights from the 2019 Nationwide Emergency Department Sample

Few studies have explored the incidence and general trends in knife-related victimizations in the United States (US), especially in settings where preventive interventions can potentially be initiated such as emergency departments (EDs). The goal of the present investigation was to provide an empirical portrait of the psychosocial and behavioral health characteristics of patients assaulted by sharp objects, particularly knives, as revealed in EDs in the US, as less research has focused on knife victimization in the US than internationally. This study uses data from the 2019 Nationwide Emergency Department Sample (NEDS), which is part of the Healthcare Cost and Utilization Project distributed by the Agency for Healthcare Research and Quality. Findings revealed that demographically males (especially those aged 18–25), those in poverty, and members of racially minoritized groups were more likely to be present with knife-related assault. Key factors increasing the odds of knife-related victimization treated in EDs were homelessness, legal involvement, and substance use, particularly alcohol and stimulant use disorder. Somewhat surprisingly, mental health diagnosis was not associated with increased knife-related victimization. Although EDs are critical to treating knife-related victimization, they are also potentially key points to launch prevention for high-risk individuals to reduce subsequent violence stemming from escalation of interpersonal disputes.
