Operating-Room Procedures Do Not Increase Risk of COVID-19 Infection.

BACKGROUND AND OBJECTIVES

Operating-room procedures canceled due to the COVID-19 pandemic depleted hospital revenue and potentially worsened patient outcomes through disease progression. Despite safeguards to resume elective procedures, patients remain apprehensive of contracting COVID-19 during hospitalization and recovery. We investigated symptomatic COVID-19 infection in patients undergoing operating-room procedures during the spring 2020 outbreak in Fairfield County, CT, a heavily affected New York Metropolitan area.

METHODS

We retrospectively analyzed 419 operating-room patients in Danbury and Norwalk Hospitals between 3/16/20 and 5/19/20. COVID-19 infection was assessed through test results or documented well-being within 2 weeks postdischarge. Variables studied were procedure classification, length of stay, and discharge disposition. Postprocedural COVID-19 infection was analyzed using binomial tests comparing rates to state-mandated infection data.

RESULTS

Six patients developed COVID-19 after 212 urgent-elective and 207 emergent procedures. Overall postprocedural infection risk was equivalent to community infection risk ( > .05). No infections occurred in 1-2 day stays or urgent-elective procedures with discharge home (both < .05). Discharges home reduced the risk to one-sixth of community spread ( = .03). Risk of infection doubled in hospitalizations > 5 days ( = .05) and quadrupled in discharges to extended care facilities ( = .01).

DISCUSSION

Operating-room procedures did not increase the risk of symptomatic COVID-19 infection during an outbreak. Urgent-elective and emergent procedures during further outbreaks appear safe when anticipating short stays with discharges home. When anticipating prolonged hospitalization or discharges to facilities, appropriate delay of urgent-elective procedures may minimize risk of infection.
