ABSTRACT
Objectives: In this study, it was aimed to determine demographic and clinical characteristics, supportive treatments in intensive care unit (ICU), mortality rates and factors affecting mortality by grouping COVID-19 intensive care patients as octogenarian and nonagenarian groups, and patients younger than 80-years-old. Method(s): The patients aged >=18 years diagnosed with COVID-19 with PCR positivity in ICUs between March 19, 2020 and March 31, 2021 were included in this retrospective observational study. Result(s): Of the 1004 PCR positive patients, 58.7% were male. The youngest patient was 20, the oldest patient was 100-years-old. There were 738 patients in Group 1 (20-79 years) and 266 patients in Group 2 (>=80 years). Between the two groups, gender, APACHE II score, need for intubation, need for vasopressor/inotrope, and patients in need of care were higher in Group 2 (p<0.001 for all). Only the patients in Group 1 were established ECMO. Hypertension (HT), cardiovascular, respiratory and neurological diseases, number of comorbidity, and mortality rate were higher significantly in Group 2 (p<0.001, p=0.001, p=0.006, p<0.001, p<0.001, and p<0.001;respectively). Age, male gender, HT, intubation, and vasopressor/inotrope requirement were found to be predictors of mortality. Conclusion(s): COVID-19 may have a more severe and fatal course in the octogenerian and nonagenerian age group with high comorbidity in the ICU.©Copyright 2022 by The Cardiovascular Thoracic Anaesthesia and Intensive Care.
