Methods: In this prospective study conducted between December 2021 and December 2023, data on the number of hospitalized patients, bed occupancy rate, average length of stay in the ICU, average number of admissions to the ICU, average APACHE scores of the patients on admission to the ICU, number of successful CPRs, number of deaths and discharges, and predicted mortality rate were extracted from a questionnaire completed for all COVID-19 ICUs of Imam Reza Hospital in Tabriz, Iran. Data were analyzed using SPSS ver22 software. Results: In this study, a total of 3188 COVID-19 patients were hospitalized in the ICUs of Imam Reza Hospital during the specified period, with 2342 patients in 2021 and 846 patients in 2022. The average number of hospitalized patients per month in Imam Reza Educational Medical Center during the study period was 132.08. The average APACHE score of COVID patients on admission to the center's ICUs was on average 6.31 points higher than the global average (P < 0.001). In addition, the average predicted mortality rate in the center's COVID ICUs was approximately 1.08 lower than the reported global rate (P = 0.001). Conclusion: The results of this study demonstrate the significant management capabilities of the hospital. The high number of COVID-19 cases, the majority of which were patients with more severe disease, confirms good to excellent patient management outcomes. https://aacc.tums.ac.ir/index.php/aacc/article/view/1557
