POOR AGREEMENT BETWEEN CLINICAL SCREENING AND UNIVERSAL PRE-PROCEDURE SARS-CoV-2 PCR TESTING PRIOR TO ENDOSCOPY

Le résumé fourni par la source

INTRODUCTION: scientific societies recommend screening for SARS-CoV-2 in patients prior to endoscopy. There is no solid evidence regarding the efficiency of universal screening by PCR testing for SARS-CoV-2. The present study aimed to assess the usefulness of clinical screening and universal pre-procedure PCR testing for the identification of patients capable of transmitting the SARS-CoV-2 infection. Concordance between both strategies was also evaluated. METHOD: a retrospective review was performed in a consecutive cohort of patients undergoing endoscopy at a tertiary teaching hospital between April 22 and June 22, 2020, following a screening protocol. RESULTS: three hundred and sixty-one patients were included. Clinical screening detected 13 patients with a high risk of infection (3.6 %, 95 % CI: 2.62-4.58) while the pre-procedure PCR test was positive in five patients (1.40 %, 95 % CI: 0.20-2.60). Three patients developed COVID-19 and one died from the disease. Agreement between both strategies was poor, with a kappa value of 0.093 (95 % CI: 0.001-0.185). Clinical screening only identified one of the five patients with a positive PCR test. CONCLUSION: clinical screening prior to endoscopy has a poor agreement with pre-procedure PCR testing.
