Abstract
Background: The clinical characteristics of COVID-19 are diverse from a simple common cold symptom to acute respiratory distress syndrome (ARDS). In the present study, we attempted to identify the associated factors in surviving COVID-19 intensive care unit (ICU) patients based on their clinical characteristics.
Materials and Methods: This retrospective study was performed on 114 laboratory‑confirmed COVID‑19 patients admitted to the intensive care units of Hormozgan University of Medical Sciences, Iran. Demographic, medical, clinical manifestations at admission time, and outcome data were obtained from the patient’s medical records.
Results: Of 114 participants included in this study, 64.9% were men. Their mean age was approximately 54 years old, 69.3% of them died and 30.7% of them were discharged. The mortality rate was 2.96 times higher in people who had ARDS compared to their counterparts, 1.37 times higher in people under non-invasive ventilation, and 3.56 times higher in people under invasive mechanical ventilation.
Three common underlying diseases among them were hypertension in 34.2%, diabetes in 23.7%, and cardiovascular diseases in 17.5% of them. Alive and dead patients significantly differed only in the following laboratory tests: D-dimer, urea, troponin, Procalcitonin, and ferritin.
Conclusion: The mortality rate among COVID-19 patients admitted to ICU is generally high. Dyspnea, as the initial presentation and comorbidity, especially hypertension, diabetes, and cardiovascular diseases, may be associated with a higher risk of developing severe disease and consequent mortality. Therefore, D-dimer, urea, troponin, Procalcitonin, and ferritin at the time of hospital admission could predict the severity of the disease and its probable mortality.
