Kaplan-Meier plots with 95%-confidence bands for survival among patients who tested positive for COVID-19 any time before surgery vs matched COVID-19 negative patients. Each COVID(+) patient was matched to up to 3 COVID(−) patients based on age, sex, race, ethnicity, BMI, smoking status, CPT code, anesthesia type, ASA class, case urgency, CCI, and cancer history. Outcomes were observed 3/1/20–3/26/21. (A) Survival from all-cause mortality; (B) pulmonary complications are a composite of pneumonia, acute respiratory failure, and acute respiratory distress syndrome; (C) thrombotic complications are a composite of ischemic stroke, myocardial infarction, venous thromboembolism, and arterial thromboembolism; (D) septic complications are a composite of sepsis from an unspecified source, gram-negative sepsis, and post-procedural septic shock.
