Effectiveness of a neonatal intensive care unit access intercom linked audiovisual display monitor highlighting infection control procedures.

This prospective interventional study aimed at increasing knowledge and adherence to 4 infection control standards by visitors to a neonatal intensive care unit. Visitors were interviewed and observed for knowledge of and adherence to the standards pre- and postinstallation of an audiovisual display monitor, which demonstrates handwashing and delivers an auditory and written list of the standards. Handwashing adherence and watch removal improved from 79.2% to 100% and 67% to 89.7%, respectively. Recall of the standards increased from 19% to 81%.
