Background: The timing of screening for SARS-CoV-2 preoperatively by RT-PCR/CBNAAT, isolation protocols in preoperative wards, operation theatres, and postoperative wards are not well established.
Methods: Evaluating the effectiveness of maintaining three pathways of two COVID-19 negative pathways (1) immediate testing pathway (2) isolation, or quarantine for five days and testing prior to surgery pathway, and (3) the tested COVID-19-positive pathway, was the aim of the study. The primary objective was to assess the utility and outcome of the two COVID-19 negative pathways adopted before surgery in terms of infectivity (seroconversion; COVID-19 positivity rate before surgery and symptomatic COVID-19 disease after surgery).
