Background and Aim: With the outbreak of the COVID-19 pandemic, the performance of hospitals were affected, and changes were made in the utilization of hospital services. Analyzing hospital performance data during the COVID-19 pandemic can provide insights into service utilization patterns and care outcomes for managers and policymakers. This study was conducted to investigate the impact of COVID-19 on selected outcome indicators in the hospitals of Shahid Beheshti University of Medical Sciences, Tehran.
Materials and Methods: This research was descriptive-analytical and of the time series analysis type. Six outcome indicators were considered: hospitalization rate, bed occupancy rate, the average length of stay, emergency visits, laboratory tests, and imaging requests. Related data from 12 affiliated hospitals from 2017-2019 (pre-COVID) and 2020 (post-COVID) were obtained from the hospital's intelligent management system. The data were analyzed using R software's interrupted time series analysis method.
Results: The hospitalization rate (P=0.015), bed occupancy rate (P=0.04), and the number of laboratory tests (P=0.003) significantly increased immediately after the outbreak of the pandemic. In contrast, emergency visits (P=0.034) have significantly decreased. The bed occupancy rate and the number of imaging requests showed no significant change. The decrease in emergency room visits within one year after the pandemic was significant, but the changes in other outcome indicators were non-significant (P>0.05).
Conclusion: Understanding the changes and impact of a major event on hospital outcome indicators is necessary for decision-makers to effectively plan for resource allocation and effective pandemic response. The outbreak of COVID-19 has caused a change in performance and hospital outcomes by affecting the supply and demand of services. In a year after the pandemic's beginning, except for emergency visits, the other indicators have not experienced significant changes. Preservation of essential services such as emergency room visits is recommended in the strategy of rapid response to an epidemic outbreak and public campaigns to encourage people to seek medical care if needed in future waves of the pandemic.
