Recent COVID-19 infection is associated with increased mortality in the ambulatory surgery population
Main findingResult — go to the resultOdds ratio 2.51Authors' conclusion
A COVID-19 positive diagnosis is associated with significantly higher risk of all-cause mortality following ambulatory surgery. This mortality risk is greatest in patients that undergo ambulatory surgery within 45 days of testing positive for COVID-19.
