ABSTRACT
INTRODUCTION AND OBJECTIVE: Continued vigilance of operative outcomes of COVID-19 patients is important given the relative novelty of the SARS-CoV-2 infection. We here sought to evaluate the 30-day mortality and cardiopulmonary adverse event rates in patients undergoing emergency surgery with perioperative COVID-19 infection, in comparison to a control group of medically managed COVID-19 patients that did not require surgical intervention. METHODS: A retrospective review of electronic medical data from a single tertiary-care center in Michigan was undertaken. Patients who had tested positive for SARS-CoV-2 infection either 7 days before or within 30 days after surgery during March-May 2020 were included in the study (n=52). Propensity score matched (1:6) patients who had been positive for SARS-CoV-2 infection during this time-period but did not undergo surgery were used as controls (n=314, Figure 1). The primary endpoint was 30-day mortality. Secondary endpoints included cardiac and pulmonary complications. Multivariable logistic regression analyses were utilized to account for baseline differences. A pvalue <0.05 was considered significant. RESULTS: The 30-day mortality (17.3% vs 13.1%, p=0.408) and cardiac (28.9% vs 19.1%, p=0.107) and pulmonary complication (55.8% vs 49.4%, p=0.392) rates were similar in patients in the surgical versus non-surgical group, respectively. Multivariable analyses confirmed that an emergency surgical intervention was not associated with increased odds for any of the studied adverse events (p >0.10 for all 3 endpoints). CONCLUSIONS: Patients undergoing emergency surgery with a co-diagnosis of SARS-CoV-2 infection in the perioperative period do not have an increased risk for short-term mortality or cardiopulmonary complications compared to the medically treated COVID-19 patients.
