MP58-09 RISK OF 30-DAY MORTALITY AND CARDIOPULMONARY COMPLICATIONS IN PATIENTS UNDERGOING EMERGENCY SURGERY WITH PERIOPERATIVE SARS-COV-2 INFECTION

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 0.10 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.
