AbstractAlthough many concerns have been raised on increased self-harm or suicide attempts since the emergence of the coronavirus disease 2019 (COVID-19) pandemic, the numbers of studies reported no consistent increase. This study aimed to analyze the data on the request for emergency medical service (EMS) in Daegu Metropolitan City in Korea to investigate the effects of the COVID-19 pandemic on the incidence and types of suicidal patients. Data of 4480 cases requesting EMS related to self-harm or suicide 1 year before and after the COVID-19 pandemic were retrospectively comparatively analyzed (February 19, 2019-February 18, 2021). The number of EMS requests for self-harm and suicide increased after the pandemic compared to that before the pandemic (daily mean request 5.83 [±2.597] vs 6.43 [±2.918]). In particular, the number of female patients increased per day on average (2.61 [±1.717] vs 3.17 [±1.893]). With respect to the reasons for the request, committed self-harm and attempts to commit self-harm increased, whereas the presumption against suicide decreased. With respect to consciousness levels, the number of alert patients increased, whereas the number of transport cases decreased. For the method of the attempt, hanging and carbon monoxide/gas poisoning decreased, whereas jumping from a height and drowning increased. The number of patients with psychiatric history and those with other chronic illnesses increased. In multivariate regression analysis, women (OR 1.227, 95% CI = 1.072-1.405, P = .003), patients with psychiatric diseases (OR 1.223, 95% CI = 1.031-1.450, P = .021), patients with other chronic illnesses (OR 1.510, 95% CI = 1.127-2.023, P = .006), and CO or gas poisoning (not attempted) (OR 1.349, 95% CI = 1.038-1.753, P = .025) showed statistically significant differences. Among the request for EMS, requests for committed self-harm and attempts to commit suicide increased. Medical support and measures for mental health and emergency medical systems should be established for female patients and patients with psychiatric or other chronic diseases.Copyright © 2022 the Author(s).
