Objectives:

to evaluate the impact of the COVID-19 on the hospital key performance indicators using the diagnosis-related groups (DRG). To compare the results of the Angiology and Vascular Surgery Department of the University Hospital of Cabueñes (HUCAB) with the database of the Ministry of Health.

Material and methods:

hospital discharges from the Vascular Surgery Department of the HUCAB during the years 2019, 2020 and 2021. All patients refined (APR)-DRG system was extracted for discharge coding. The hospital key indicators studied were: number of discharges, mortality, mean stay (EM) and mean weight (PM) of the DRG. The overall results per year and according to the most prevalent DRGs were studied. The results obtained were compared with the annual data from the coding of the Minimum Basic Data Set (CMBD) of the Ministry of Health. The configured EM by adjusting the performance of the standard (EMAF) and by the casuistry (EMAC), the index of the adjusted EM (IEMA), the functional index (FI), casuistic index (CI) and the number of avoidable hospital stays were also analyzed.

Results:

number of discharges: it was 10 % inferior in 2020 compared to 2019. Discharges of the GRD 181 linked to admissions from the Emergency increased more than 50 % during 2020 and more than 100 % in 2021 compared to 2019. Mortality: there was no significant increase. EM: it decreased 20 % in 2020 and 18 % in 2021, compared to 2019. PM: it increased progressively to 7.7% on average in 2021. EMAF: it was superior to standard EM. The number of stays saved was higher than expected.

Conclusions:

the pandemic of COVID-19 influenced the hospital key performance indicators studied, reducing the number of discharges and ME and increasing the PM of the DRGs. The number of avoidable stays saved was greater than the standard.
