Standard Versus Advanced Protective Measures in a COVID-Free Surgical Pathway.

Abstract

Introduction The importance of coronavirus disease (COVID)-free surgical pathways during the coronavirus disease 2019 (COVID-19) pandemic has been demonstrated. However, the extent of protective measures to be applied against severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), particularly before vaccines became available, remained unclear. Methods This retrospective study included all SARS-CoV-2-negative patients admitted to the COVID-free pathway of a regional abdominal surgery hub center in Northern Italy over 12 months, before the vaccination campaign. During the first seven months, basic protective measures against SARS-CoV-2 were adopted (surgical masks, swabs for symptomatic patients, and intra- or interhospital transfers), since patients were treated as effectively negative (standard management). During the last five months, advanced measures were implemented (enhanced personal protections and systematic control swabs), as patients were considered potentially positive (advanced management). The aim of this article was to compare SARS-CoV-2 incidence and surgical outcomes in these periods. Results A total of283 and 194 patients were admitted under standard and advanced management, respectively; pre-admission data differed only in the rate of previous SARS-CoV-2 infection (2.5% versus 6.7%, p= 0.034). The SARS-CoV-2 incidence was 3.9% and 3.1% for standard and advanced periods, respectively (p = 0.835). Two internal outbreaks developed during the standard phase. The advanced protocol significantly increased the rate of patients re-tested for SARS-CoV-2 (83% versus 41.7%, p < 0.001) and allowed early detection of all infections, which remained sporadic. Surgical outcomes were similar. Conclusions Advanced management was instrumental in detecting positive patients early and preventing outbreaks, without affecting surgical results; accordingly, it stands as a reproducible model for future pandemic scenarios.
