Colorectal Surgery Outcomes in the United States During the COVID-19 Pandemic.

ABSTRACT

INTRODUCTION: The purpose of this study was to assess colorectal surgery outcomes, discharge destination, and readmission in the United States during the COVID-19 pandemic. METHODS: Adult colorectal surgery patients in the American College of Surgeons National Surgical Quality Improvement Program database (2019-2020) and its colectomy and proctectomy procedure-targeted files were included. The prepandemic time period was defined from April 1, 2019 to December 31, 2019. The pandemic time period was defined from April 1, 2020 to December 31, 2020 in quarterly intervals (Q2 April-June; Q3 July-September; Q4 October-December). Factors associated with morbidity and in-hospital mortality were assessed using multivariable logistic regression. RESULTS: Among 62,393 patients, 34,810 patients (55.8%) underwent colorectal surgery prepandemic and 27,583 (44.2%) during the pandemic. Patients who had surgery during the pandemic had higher American Society of Anesthesiologists class and presented more frequently with dependent functional status. The proportion of emergent surgeries increased (12.7% prepandemic versus 15.2% pandemic, P < 0.001), with less laparoscopic cases (54.0% versus 51.0%, P < 0.001). Higher rates of morbidity with a greater proportion of discharges to home and lesser proportion of discharges to skilled care facilities were observed with no considerable differences in length of stay or worsening readmission rates. Multivariable analysis demonstrated increased odds of overall and serious morbidity and in-hospital mortality, during Q3 and/or Q4 of the 2020 pandemic. CONCLUSIONS: Differences in hospital presentation, inpatient care, and discharge disposition of colorectal surgery patients were observed during the COVID-19 pandemic. Pandemic responses should emphasize balancing resource allocation, educating patients and providers on timely medical workup and management, and optimizing discharge coordination pathways.
