Aims To describe the results of pre-endoscopic screening with Sars-CoV-2 RT-PCR performed in asymptomatic patients scheduled for elective endoscopy in our center in the 2nd, 3rd and 4th epidemic surges.

To analyze the correlation between those tested positive with the epidemiological data published by the Catalonian Health Department (CHD).

Methods We conducted an observational retrospective study of our screening spanning 22/6/2020-20/06/2021. We collected the effective potential growth (EPG, an index measuring outbreak risk) weekly and the cumulative incidence (CI) at 7/14 days. Epidemiological data were collected from the CHD and trended with our results.

Results We performed 5.808 tests yielding 125 positive results (2.15%). The highest positive rate was recorded in January-2021 (9.26%). All positive results were obtained in weeks considered of high or very high risk (EPG>100). We found a strong correlation (Rho=0.796; p<0.001) between weekly positive rate and EPG. The number of positive results was significantly lower on weeks with EPG<100 compared with EPG>100. Taking the EPG value from one and two weeks before to plan the screening, up to 876 tests could be avoided with only one positive result to account.

Conclusions Pre-endoscopic screening identifies a significant number of asymptomatic patients corresponding to more than 9% in high-risk weeks. Epidemiological data (EPG/7-CI/14-CI) for up to 2 weeks prior show a significant correlation with our screening results. EPG of up to 2 weeks prior identifies the weeks with least risk and could be useful to plan pre-endoscopic screening and adequate material and human resources.
