About

With the knowledge of currently transmitted omicron variant being less virulent, over 90 percent of the Chinese population is fully vaccinated, and the Chinese health workers have sufficient experience treating the illness. China 's epidemic prevention and control has entered a new stage to restore the normal functioning of society and basic medical services, On Dec, 7, China released a circular on further optimizing its COVID-19 response, announcing 10 new prevention and control measures.This has marked the watershed for sharply increased number of elective surgical patients diagnosed with COVID-19 during preoperativley, fully recovered or during recovery.

Beijing faced a wave of omicron infection starting that would result in of a wide range of population infections. At which time there is limited evidence regarding the optimal timing of surgery following SARS-CoV-2 infection especially for omiron among Chinsese patients .This study intends to explore the relationship between the incidence of postoperative complications after elective surgery and COVID-19 infection in Peking Union Medical College Hospital, and provide data support for the policy formulation of elective surgical timing for patients after COVID-19 infection.
