abstract="AIM: Self-harm is a common ambulance call and is potentially affected by the COVID-19 pandemic. The aim of this study was to investigate whether the incidence of ambulance transport due to self-harm increased in 2020. <br><br>METHODS: We undertook a population-based observational study using a database from the Osaka prefectural government. Ambulance transport of patients due to self-harm from 2016 through 2020 was investigated. We estimated adjusted incidence rate ratios using a Poisson regression model to compare the annual incidence rates of ambulance transport in 2017-2020 with those in 2016. We also provided age-stratified analysis. <br><br>RESULTS: We analyzed 13,648 patients. There was no difference in the incidence of ambulance transport due to self-harm in 2017, 2018, 2019, and 2020 compared with 2016. In the age group of 20-29 years, despite no difference in 2017-2019 compared with 2016, we found a 13.8% increase in the incidence of ambulance transport due to self-harm in 2020 (adjusted incidence rate ratio, 1.138; 95% confidence interval, 1.025-1.265). <br><br>CONCLUSIONS: Although there was no difference in the incidence of ambulance transport due to self-harm in 2017-2019, that in 2020 increased in the age group of 20-29 years.<p /> <p>Language: en</p>",
