Tuberk Toraks. 2022 Mar;70(1):63-75. doi: 10.5578/tt.20229908.

Abstract

Introduction: This study aimed to evaluate the epidemiological, clinical, laboratory characteristics and treatment and clinical outcomes of severe COVID19 cases from a 3rd degree intensive care unit in Turkey.

Materials and methods: The study was conducted in a level three, 16-bed COVID intensive care unit. The investigation was planned as a retrospective and observational study. Patients who were admitted with COVID-19 pneumonia and respiratory failure in the intensive care unit between March 2020 and March 2021 and followed up due to critical illness were evaluated.

Result: A total of 213 patients that were admitted to the intensive care unit with the diagnosis of COVID-19 pneumonia were included in the study. Median age of the patients was 66 (IQR 56.5-74) years, and 134 (62.9%) were males. One hundred and sixty-six (77.9%) of the patients had at least one comorbidity. Patients were followed up mainly with invasive mechanical ventilation [104 (48.8%)] and high flow nasal cannula [67 (31.5%)]. Median number of days was 7 (IQR 4-10) and included the first symptom onset to intensive care admission. The time to intubation was 9 (IQR 4-15) days, and the median day to intensive care discharge was 16 (IQR 11-23). After the symptoms started, first tocilizumab 9 (IQR 5-11) and pulse steroid treatment 8 (IQR 3-11) were found to be close to each other. In total, 95 (44.6%) of the 213 patients died.

Conclusions: SARS-CoV-2 associated viral disease can progress after simple symptoms to hospital admission in a median of four days and to intensive care admission requiring intubation in a median of nine days. We believe that a better understanding of the clinical course of COVID-19 and its change between centers can be revealed through sharing information from different countries and centers.
