Firearm Injury Rates Before and After the COVID-19 Pandemic: A Retrospective Prevalence Study


Firearm injuries are a public health epidemic in the United States. Patients with firearm injuries frequently present to emergency departments (ED) and level I trauma hospitals for care of acute firearm injury. Since the beginning of the COVID- 19 Pandemic, the population that experiences common emergent health issues (stroke, heart attack, etc) have decreased in their volume of visits to the ED. Using a retrospective prevalence study, we will examine the number of patients that present to a network of Rhode Island hospitals (including a level 1 trauma center) that receive an ICD-10 diagnosis of firearm injury. We will utilize an independent sample t-test analysis to compare injury rate differences between the same time periods In 2019 and 2020. We hypothesize that there has been an uptick in the rate of ED visits for firearm injuries before and after the onset of the COVID-19 Pandemic.
