Influence of Covid-19 Restrictions on Urban Violence.

ABSTRACT

We investigated whether the COVID-19 pandemic affected rates of interpersonal violence (IV). A retrospective study was performed using city-wide crime data and the trauma registry at one high-volume trauma center pre-pandemic [PP] (March-October 2019) and during the pandemic [PA] (March-October 2020). The proportion of trauma admissions attributable to IV remained unchanged from PP to PA, but IV increased as a proportion of overall crime (34% to 41%, p<0.001). Assaults decreased, but there was a proportionate increase in penetrating trauma which was mostly attributable to firearms. Despite a reduction in admissions due to IV in the first 4 months of the pandemic, the rates of violence subsequently exceeded that of the same months in 2019. The cause of the observed increase of IV is multi-factorial. Future studies aimed at identifying the root causes are essential to mitigate violence during this ongoing health crisis.
