Characteristics of burn injury during COVID-19 pandemic in Tokyo: A descriptive study

Coronavirus disease 2019 (COVID-19) has drastically changed everyday life worldwide. This study aimed to determine how COVID-19 affected the characteristics and outcomes of patients with severe burn injury by examining a city-wide burn database in Tokyo.

A descriptive study was conducted in 14 burn centers using the Tokyo Burn Unit Association registry from 1999-2020. The pandemic started in 2020, while the stay-at-home order lasted from April to May. The demographics, mechanisms, severity, and clinical outcomes were assessed before and during these two time periods.

In total, 7061 patients with burn injury were enrolled. During the pandemic, there were less patients during the pandemic than previous years, except for April-May; this decreased toward the end of 2020. There were also more scald/contact burns in the upper extremity, less intended and assault injuries, shorter length of hospital stay, and lower in-hospital mortality. During the stay-at-home order, there was increased incidence of flame burns, inhalation injuries, and in-hospital mortality, as well as higher total body surface area of full-thickness burns.

This study described the characteristics of burns during the COVID-19 pandemic. The association between the stay-at-home order and severity of burns should be further examined.
