Survival Rate and Related Factors in Patients with COVID19 Undergoing Major Surgeries: A Cross-sectional study

Introduction: Surgery is one of the factors that may accelerate and intensify the progression of COVID-19. The present study was conducted with the aim of investigating the survival rate and related factors in patients with COVID19 undergoing a major surgery. Methods: In this cross-sectional-analytical study, 43 patients with COVID-19 who underwent a major surgery in Kowsar Semnan Hospital were examined in 2021. The data collection tool was a checklist including demographic and clinical variables, which was extracted from the patients' files by referring to the medical records section. Survival of patients after surgery was also checked through telephone calls. The data was entered into Stata 14 software and Chi-squared test was used to check the relationship between variables with 6-month survival. Results: The mean age (± S.D) of the patients age was 50/86 (± 23/14). . The mean (± standard deviation) age of male and female patients was 47.73 (± 20.89) and 55.65 (± 26.15), respectively.The survival rate 6 months after surgery was significantly lower in patients over 50 years old, who were admitted to the intensive care unit, and were suffering from an underlying disease, high body mass index, the presence of trauma and neurosurgery (P<0/05). Conclusion: Almost only half of the patients with COVID19 survived 6 months after major surgery, and age over 50, hospitalization in the intensive care unit, underlying disease, high body mass index, and presence of trauma and neurosurgery were the most important factors determining this decrease in survival.
