Introduction Barrier enclosure devices were introduced to protect against infectious disease transmission during aerosol generating medical procedures (AGMP). Recent discussion in the medical community has led to new designs and adoption despite limited evidence. A scoping review was conducted to characterize devices being used and their performance. Methods We conducted a scoping review of formal databases (MEDLINE, Embase, Cochrane Database of Systematic Reviews, CENTRAL, Scopus), grey literature, and hand-searched relevant journals. Forward and reverse citation searching was completed on included articles. Article/full-text screening and data extraction was performed by two independent reviewers. Studies were categorized by publication type, device category, intended medical use, and outcomes (efficacy – ability to contain particles; efficiency – time to complete AGMP; and usability – user experience). Results Searches identified 6489 studies and 123 met criteria for inclusion (k = 0.81 title/abstract, k = 0.77 full-text). Most articles were published in 2020 (98%, n = 120) as letters/commentaries (58%, n = 71). Box systems represented 42% ( n = 52) of systems described, while plastic sheet systems accounted for 54% ( n = 66). The majority were used for airway management (67%, n = 83). Only half of articles described outcome measures (54%, n = 67); 82% ( n = 55) reporting efficacy, 39% ( n = 26) on usability, and 15% ( n = 10) on efficiency. Efficacy of devices in containing aerosols was limited and frequently dependent on use of suction devices. Conclusions While use of various barrier enclosure devices has become widespread during this pandemic, objective data of efficacy, efficiency, and usability is limited. Further controlled studies are required before adoption into routine clinical practice.

Background and Aim Minimizing endoscopist exposure to bodily fluids is important for reducing the risk of infection transmission. This study investigated the patient‐endoscopist vertical distance necessary to minimize an endoscopist's facial exposure to a patient's visible droplets during upper gastrointestinal endoscopy and the ability of a new device to prevent droplets from reaching the endoscopist's face. Methods A model was developed to simulate a patient experiencing a forceful cough during an upper gastrointestinal endoscopy with a model endoscopist. Fluorescent dye was expelled from the model patient's mouth towards the model endoscopist during simulated coughs; dye adhesion to the model endoscopist's face was evaluated using ultraviolet light. The simulation was repeated with the model patient positioned 70–100 cm above the floor, with and without a barrier to shield the patient's face. The accuracy of the cough simulation model and the relationship between patient‐endoscopist vertical distance and endoscopist's facial exposure were evaluated. Results The flow dynamics of the cough simulation model were similar to that of an actual human cough. There was a significant inverse correlation between the patient‐endoscopist vertical distance and the model endoscopist's facial exposure, with positive exposures decreasing from 87% at 70 cm to 0% at 100 cm ( P < 0.001). The barrier device prevented facial exposure to droplets at all distances. Conclusions We found that positioning the patient at least 100 cm below the top of the endoscopist's head or using a barrier device minimized the endoscopist's facial exposure to visible droplets during upper gastrointestinal endoscopy.
