Pre-Endoscopy real-time PCR testing for SARS-CoV2 does not reduce health care workers infection and is associated with a higher reduction of endoscopic activity in an outpatient setting.

Objective: The role of pre-procedure SARS-CoV2 testing in digestive endoscopy is still debated. AGA guidelines recommend against pre-procedure testing considering low prevalence of SARS- CoV2 infection in the general population and low incidence of infection among endoscopy units Health Care Workers (HCWs). However, no studies have compared pre-procedure testing associated to symptom screening vs. symptom screening alone in reducing the risk of infection for HCWs. Main aim of the present study is to compare the risk of infection for HCWs in different Endoscopy Units adopting different pre-endoscopy screening and operating in two nearby hospital of the same region in Northern Italy in pre-vaccination period. For outpatients in the Endoscopy Unit of Trento (Unit 1) only pre-procedure symptom screening was performed, while in the Endoscopy Unit of Bolzano (Unit 2) pre-procedure symptom screening and negative pre-procedure real-time PCR were requested. Secondary aims were to assess the impact of pre-procedure real-time PCR testing on endoscopic activity and diagnostic delay. Design: Retrospective data collection on a prospectively maintained database was performed, including outpatient endoscopy procedures performed between June 1st 2020 and February 28th 2021 in Unit 1 and Unit 2. Results: No differences in terms of infection rate in HCWs have been identified in Unit 1 and Unit 2 (9.0 vs. 19.3% P=0.2) over a nine-month period. Moreover, in the unit performing pre- procedure real-time PCR before endoscopy a significantly higher reduction in endoscopic activity has been recorded (61.9% vs. 53.4%; P<0.01). In patients with positive real-time PCR, endoscopy was performed with a mean delay of 61.7 days (range 9-294) and 22.5% of them were lost at follow-up and did not undergo any endoscopic procedure in the following 12 months. Conclusions: This study supports the AGA recommendation suggesting that pre-endoscopy real-time PCR is an expensive and time-consuming procedure without proven benefits in an outpatient setting.

Impact of the SARS-CoV-2 pandemic on gastroenterology units in Italy: A national survey

Aims This is a prospective observational web-based survey aimed to assess the impact of SARS-CoV-2 pandemic onGastroenterology Units in Italy. Methods All members of the Italian Society of Gastroenterology (SIGE) were invited to answer a 39-point multiple-choiceweb-based survey between March 30 thand April 7 th2020. Results Data of 121 hospitals from all 20 Italian regions were analyzed. Overall, 10.7 % of Gastroenterology divisions havebeen converted to COVID Units. Outpatients consultations, endoscopic and ultrasound procedures were limited to urgenciesand oncology indications in 85.1 %, 96.2 % and 72.2 % of Units, respectively, and 46.7 % of Units suspended the screeningfor colorectal cancer.In order to guarantee the ordinary follow-up of outpatients, 83/121 (68.6 %) divisions activated aremote consultancy service (63.9 % by phone, 31.3 % by email, 4.8 % by video). Overall, 112/121 (92.6 %) GI Units issued and followed a specific protocol for the management of patients with suspectedor confirmed SARS-CoV-2 infection. The 72.2 % of the staff received proper training for the use of personal protective equipment, although 45.5 % did not havesufficient devices for an adequate replacement. With regard to PPE availability, N95/FFP2-3 masks were available in 91/121 (75.2 %), surgical masks in 115/121 (95.0 %),gloves in 117/121 (96.7 %), disposable gown in 100/121 (82.6 %), hairnet in 104/121 (85.9 %), goggles in 78/121 (64.5 %)and boots in 57/121 (47.1 %) of divisions. Finally, in 41/121 GI divisions (33.9 %) there was at least one healthcare professional who got infected, in a total of 132subjects, of which 121/132 from divisions not-converted to COVID Units and 75/132 from high-prevalence areas. Conclusions Substantial changes of practice and reduction of procedures have been recorded in the entire country duringthe first wave of the pandemic. The long-term impact of such modifications is difficult to estimate but potentially very riskyfor many digestive diseases.
