Objective: The ongoing pandemic of the coronavirus disease 2019 (COVID-19), which originated from Wuhan, China, has been identified to be caused by the novel beta coronavirus, severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). COVID-19 has been spreading rapidly worldwide within just a few months. Our aims were to analyze clinical and laboratory abnormalities in ICU patients with COVID-19, in order to define which predictors can distinguish between those who are at higher risk of developing fatal versus non-fatal forms of the disease. Methods: A descriptive cross-sectional survey was used; demographics, comorbidities, symptoms, laboratory parameters at ICU admission, and clinical outcomes for the adult patients admitted to ICU were collected from five hospitals in Saudi Arabia. Results: A total of 86 patients with COVID-19 admitted in ICU, 50 patients died, 23 recovered, and 13 were still admitted, with a mortality rate of 58.1%. Septic shock (OR (95% CI): 58.1 (5.97-7812.8), p < 0.001) and acute kidney injury (AKI) (OR (95% CI): 7.279 (1.191-65.43), p = 0.032) had a significant impact on mortality. Cox proportionalhazards regression analysis revealed that septic shock (HR (95% CI): 9.502 (2.958-30.524), p < 0.001) and neutrophil count (HR (95% CI): 1.053 (1.023-1.085), p < 0.001) were significant predictors for mortality. Conclusion: Septic shock, AKI, and high neutrophil count were found to be predictive of death in these patients. Further studies are needed to aid efficient recognition and management of severe COVID-19 patients in our population.
