Objectives: In this study we aimed to describe the clinical features, treatment, and outcomes of patients with COVID-19 admitted to the intensive care unit. Patients and methods: In this retrospective, observational study, we enrolled 116 patients (69 males, 47 females; mean age: 66.9±13.6 years; range, 23 to 93 years) with COVID-19 confirmed by PCR tests who were admitted to Manavgat State Hospital. Demographic data, symptoms, laboratory findings, comorbidities, treatment, and outcomes were collected between August 1, 2020, and January 1, 2021. Data were compared between patients who died and those who survived. Results: A total of 62 patients died, with a 53.4% mortality rate, while 54 recovered. The demographic analysis indicated that mortality for patients in the older age group (i.e., ≥60 years) was higher than those in the younger age group (84%, 68.5%). In addition, seven laboratory parameters were statistically associated with mortality: neutrophil (p<0.001), C-reactive protein (p<0.001), urea (p<0.001), lactate dehydrogenase (p<0.001), ferritin (p<0.001), D-dimer (p<0.001), and Troponin-I (p<0.001). Sixty-three patients (55%) required mechanical ventilation, and only one patient (2%) survived after mechanical ventilation. The median time from intensive care unit admission to death was 11.5 days (interquartile range 7.0-17). At 28 days and 60 days, 57 (49%) and four (3.5%) patients died, respectively. On the 72nd day, one (0.9%) patient died. Conclusion: Neutrophil, C-reactive protein, urea, lactate dehydrogenase, ferritin, D-dimer, and Troponin-I counts 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. Keywords: COVID-19, CRP, intensive care units, Manavgat, non-survivors, survivors.
