Predictors of Mortality among Intensive Care Unit (ICU) Hospitalized Diabetic Patients with COVID-19

Objective: Diabetic patients with COVID-19 are at the higher risk of clinical complications and intensive care unit (ICU) admission. There is limited information available on the risk factors of mortality in diabetic patients with COVID-19 admitted to the ICUs. The aim of this study was identifying the mortality risk factors in diabetic patients with COVID-19 who are admitted to the ICU. Materials and Methods: In this study, we conducted a descriptive-analytical observational analysis on 391 patients admitted to the ICU for 18 months. We assessed the demographic, clinical, pharmaceutical, laboratory and imaging data of diabetic patients and statistically analyzed them to identify mortality risk factors. Results: The study found 156 (39.89%) diabetic out of 391 patients. The group of diabetic patients had significantly higher rates of endotracheal intubation (P< 0.001), mortality (P< 0.001), and complications during hospitalization due to COVID-19, including secondary bacterial infections (P = 0.005), venous thrombosis (P = 0.008), and gastrointestinal bleeding (P = 0.011), compared to the nondiabetic patient. Conclusion: Patients with diabetes who also have COVID-19 tend to experience more severe clinical outcomes and a higher mortality rate when admitted to the intensive care unit. The likelihood of mortality in these patients is closely associated with factors such as stroke occurrence, oxygenation levels, and the presence of secondary infections at the time of admission.
