Abstract

It is known that 3 ? 5% of COVID 19 patients require critical care, and the mortality of patients receiving ventilator care is known to range from 50 to 97%.  A study conducted in India found that secondary infection was associated with morality in COVID-19 patients. In this study, we compared the death rate of patients admitted to an intensive care unit before and after COVID 19 to find out the effect of Acinetobacter baumani and COVID 19 infection on death. A.baumanii infection, ventilator, charlson comorbidity index(CCI) , death, and earliest survival date were analyzed for 549 patients admitted to the intensive care unit in 2019 and 2020 and 71 patients admitted to the intensive care unit in 2021. Those who stayed in the ICU for less than 2 days were excluded from the analysis. Divided into pre- and post-epidemic periods of COVID 19, there was no statistical difference in ventilator application, A.baumanii identification, and mortality before and after the COVID19 epidemic (344/549 vs 41/71, p=0.422; 96/549, 14/71, p=0.64; 190/359 vs 23/48, p=0.711). When only patients who underwent ventilator treatment were selected and analyzed, there was no difference in A.baumanii identification or death (82/344, 14/41, p=0.149), but a statistically significant difference in CCI was shown. (1.3/0.37 p<0.001) When survival analysis was performed on patients treated with a ventilator, the 60-day survival rate was 57.1% in the covid-19 negative group, whereas the 60-day survival rate was 35.1% in the COVID 19-positive group, which was statistically significantly lower. (p=0.01). There was no association between COVID 19 and A.baumanii infection. But COVID19 infection is an important risk factor for death in ventilator-applied patients
