Background: Healthcare workers are at ⬆️ risk for #COVID w/o adequate #PPE (20-30% of cases). In #GI, upper scopes are aerosolized-generating procedures (AGPs) & therefore even ⬆️ risk for #COVID. Lower scopes also = ⬆️ risk 2/2 some e/o AGPs w/bx + fecal oral spread. 2/13
Rec 1: Wear N95s (or better) for all upper scopes REGARDLESS of #COVID status. (Strong rec, mod quality evid). Why? Testing is inadequate & w/community spread, take universal precautions. If rapid testing for endo pts is avail, prioritize #N95s for known COVID 3/13
Rec 2: Do NOT wear surgical masks alone for upper scopes if patient has KNOWN or presumptive #COVID19 (Strong rec, low cert of evid). Why? AGPs in pts w/COVID is too high risk to risk transmission & surgical masks are insufficient w/aerosolization 4/13
Rec 3: Wear N95s (or better) for lower scopes REGARDLESS of #COVID19 status (Strong rec, low certainty of evidence). See above (Background & Rec 1) for reasoning. 5/13
Rec 4: If very resource-constrained, consider extended use (8h) or re-use (5d) of N95s for #GI scopes (Conditional rec, very low cert). Why? Data here are terrible. No direct data on viral transmission with 1+ use of N95s, or even indirect via SARS/MERS + none for AGPs! 6/13
Rec 4 more info: Limited indirect data suggest loss of fit & durability with repeated use. If you are doing this, suggest full face shield with N95s. If you have a PAPR with disposable face shields, then disinfect shields with biocidal agents between use 7/13
Rec 5: DOUBLE glove for all #GI scopes! (Strong rec, mod certainty of evid). Why? Wearing single gloves can lead to contamination of other #PPE gear like gowns and masks when doffing 8/13
Rec 6: Do scopes in #negative-pressure rooms for pts w/ KNOWN or presumptive #COVID when available (Conditional rec, very low qual evidence). For many inpts, this can be done in a neg pressure ICU room or OR. Limited data suggesting this could mitigate spread of infxn. 9/13
Rec 7: Standard #disinfecting procotols for endoscopy re-processing and cleaning are effective against #COVID19. Biocidal agents have shown efficacy here & no need to change protocols here. 10/13
