Aim: In this retrospective cohort study, it was aimed to determine the rate of Coronavirus Disease 2019 (COVID-19) test positivity in the preoperative patient population in a university hospital and to reveal the relationship between the number of preoperative COVID-19 positive patients and demographic characteristics, operation-specific findings and especially blood groups. Methods: This retrospective cohort single-center study was conducted in a university hospital. All adult patients who were scheduled for elective surgery in different surgical branches and who underwent preoperative COVID-19 screening between June 2020 and April 2021 were included. Demographic characteristics, operation-specific findings and blood groups of the patients were examined. Results: The age of the patients of COVID-19 positive group was significantly higher than the COVID-19 negative group (50.20±18.3, 47.27±17.28, respectively, p=0.030). Patients with high scores in the ASA physical status of the COVID-19 positive group were significantly higher (p<0.001). Smoking status and presence of finding on chest X-ray were significantly higher in the COVID-19 positive group (p=0.004, p=0.046, respectively). The majority of COVID-19 positive patients were processed under general anesthesia (%67.5). The patients in the COVID-19 positive group with high operative risk scores were significantly higher (p<0.001). The highest incidence in patients of the COVID-19 positive group was A Rh (+) blood group. Conclusion: The low incidence of COVID-19 compared to the general population shows the importance and effectiveness of anamnesis and polymerase chain reaction test in preoperative anesthesia evaluation in elective surgeries during the pandemic period.
