Female Victims of Firearm Intimate Partner Violence: Characterization and Lethality Predictors

Le résumé fourni par la source

Objective: To characterize the sociological risk factors for firearm intimate partner violence (IPV) among women in Texas, with a focus on lethal predictors to aid in screening and intervention guidelines. Methods: A retrospective medical and forensic chart review was conducted and supplemented by news sources, public police reports, and court records on firearm cases in Houston, TX, from 2018 to 2020. IPV was defined as a cis-gendered female victim of firearm violence from a current or ex-intimate partner. Non-IPV was defined as cis-gendered female victims of firearm violence from strangers, friends/acquaintances, gang, client, or similar relationships. Numeric variables were compared using the Wilcoxon rank-sum test and reported as median [Q1, Q3]. Categorical variables were compared using Fisher’s exact test and reported as count (%). Results: A total of 102 cases of IPV were identified. Nonspousal IPV was more prevalent than spousal (65.7% versus 34.3%). Lethal injuries, older age, home location, and head injuries were more prevalent in the IPV cohort. Older age, spousal perpetrator, home shooting location, and history of prior domestic abuse were associated with lethal IPV. There were 31 cases of murder-suicide. During the COVID-19 pandemic, IPV cases increased by 91.3%, with lethal cases increasing by 57.6%. Conclusion: Risk factors for overall IPV and lethal IPV are not the same; therefore, it is imperative that all women, irrespective of race, age, or relationship status, be screened for IPV and prior domestic violence to allow intervention and prevention of lethal IPV. Patients should also be screened for personal or partner access to firearms as firearm IPV is a highly lethal form of violence.
