Comparison of emergency department workloads before and during the COVID-19 pandemic as assessed using relative value units.

Abstract

This study aimed to assess and compare emergency department (ED) workloads by using relative value units (RVUs) before and during the COVID-19 pandemic. This retrospective observational study investigated the RVUs of a single ED from 2019 to 2021. We calculated the mean number of patients per day (PPD) for each year and selected the days when the number of patients was equal to the yearly mean PPD for each of the three years. We calculated the total RVUs per day and RVUs per patient and compared them. We analyzed the RVUs of 12 days in 2019 (mean PPD, 88), 10 days in 2020 (mean PPD, 75), and 14 days in 2021 (mean PPD, 83). The mean of the total RVUs per day were as follows: 533,057.5±66,239.1 in 2019, 505,994.6±48,935.4 in 2020, and 634,219.6±64,024.2 in 2021 (P<0.001). The RVUs per patient in the three year-groups were significantly different (6,057.5±752.7 in 2019, 6,746.6±652.5 in 2020, and 7,641.2±771.4 in 2021; P<0.001). Post hoc analyses indicated that the total RVUs per day and the RVUs per patient in 2021 were significantly higher than in 2019 or 2020, although the mean PPD in 2019 was the highest. Since the onset of the COVID-19 pandemic, the mean RVUs per patient have increased, suggesting that the workload per patient may also have increased in the regional emergency medical center.
