To determine the association between common comorbidities, ICU mortality and antimicrobial consumption among critically ill COVID 19 patients in Saudi Arabia. Methods: A retrospective observational study of patients admitted to the ICU from March 1st, 2020, through August 31st, 2021. We excluded patients who stayed <24 h in the ICU and with no confirmed COVID-19 PCR testing. Results: Of the 976 screened ICU patients, 848 were included. While there was no difference in mortality between patients with and without comorbidities, those with at least one comorbidity had a higher severity of illness (p = 0.013). Compared to survivors, non-survivors were more likely to require mechanical ventilation and vasopressor support (P < 0.001). Almost all patients received at least one antimicrobial therapy. Predictors independently associated with ICU mortality were: older age (adjusted odds ratio [AOR], 1.03; 95% confidence interval [CI], 1.01-1.04), vancomycin use (AOR, 2.69; 95% [CI], 1.65-4.37), linezolid use (AOR, 2.65; 95% [CI], 1.65-4.04), sepsis or septic shock (AOR, 6.39; 95% [CI], 3.68-11.08), Acute Kidney Injury (AKI) (AOR, 2.51; 95% [CI], 1.61-3.92) and Acute Respiratory Distress Syndrome (ARDS) (AOR, 2.03; 95% [CI], 1.61-3.92). Conclusion: Older age, vancomycin and linezolid use, sepsis/septic shock, AKI, and ARDS were negative prognostic factors in critically ill COVID-19 patients. More studies are needed to evaluate the outcomes of survived critically ill patients in relation to their vaccination status.
