COVID-19 SECOND WAVE: EXPERIENCE OF CLINIC FOR LUNG DISEASE, UNIVERSITY CLINICAL CENTER TUZLA

The objective of this paper was to present basic clinical characteristics and outcomes of treating Covid 19 patients during the second wave of the pandemic. In the retrospective study for the period from September 2020 to February 2021 it was analyzed disease history data and radiological lung changes, time from the initial start of the disease until hospitalization, parameters of blood gas analysis, comorbidities, and the outcome. The research covered 409 patients, out of which 263 (64.3%) were males. Average age was 67.07± 12.44 years (min. 20; max. 93). A high comorbidities prevalence (82.9%) was noticed out of which arterial hypertension (69.2%), diabetes mellitus (37.7%) and obesity (24.7%). On the radiological lung scan the most noticed changes were consolidation (46.2%), “ground glass” (41.3%) and interstitial changes (13%). Bilateral lung infiltration was noticed in 91.9% of the patients. Average oxygen saturation was 84.29%±10.28% (min. 35; max. 98; med. 87%). In patients with unilateral lung infiltration, average oxygen saturation was 85.09%±8.60% (med. 89%, min.61% max 98%), while in patients with bilateral lung infiltration average was 84.22%±10.42% (med. 87%, min. 35%, max. 98%). From the total all patients’ death was noticed in 35.7% cases. Morbidity of patients with unilateral lung infiltration was 27.3% and in patients with unilateral infiltration 36.4%. Hospital admission in the first week of the disease indicates the severity of the clinical condition and can be a predictor of poor outcome. Bilateral pulmonary infiltration, obesity and diabetes mellitus are risk factors for high mortality.
