Report Examining the Impact of Suicide Method Lethality on In-Hospital Mortality before and during the COVID-19 pandemic in South Korea: Insights from NEDIS

The work during this research stay examines the impact of suicide method lethality on in-hospital mortality rates before, during and after the COVID-19 pandemic in South Korea, using data from the National Emergency Department Information System (NEDIS). Suicidality is a pressing public health concern with South Korea currently reporting the highest suicide rates among OECD countries. Previous research has suggested an increase in suicide attempts, a trend that briefly declined with the onset of the pandemic before increasing again in 2021. We hypothesized that the availability of specific suicide methods was influenced by pandemic-related restrictions and analyzed whether the lethality of these methods predicted in-hospital mortality. The methodology included logistic regression to assess the association between method lethality and in-hospital mortality, controlling for confounders. Preliminary results suggest significant changes in method choice and mortality rates that correlate with pandemic dynamics. Understanding these trends may inform suicide prevention strategies and public health policies, and address the critical need for effective interventions in emergency settings.
