Risk of bacterial exposure to the endoscopist's face during endoscopy.

Background And Aims: Nonuniversal use of facial protection during endoscopy may place endoscopists at risk of exposure to blood and body fluids; however, the frequency of exposure is unknown.

Methods: A prospective 6-month study of 4 gastroenterologists using a face shield during endoscopy was undertaken. The face shield was swabbed in a standardized fashion before and at the end of the session.
