OR Traffic and Surgical Site Infections: A Quality Improvement Project.

Abstract

Operating rooms are dynamic places with a lot of movement and people working as a concerted team. Operating room traffic can be necessary (eg, retrieving an unusual supply) or unnecessary (eg, a social visit). This quality improvement project aimed to reduce the amount of OR traffic to only necessary traffic and reduce the surgical site infection rates for the orthopedic ORs in a northern California community hospital. There were three principle interventions: door signs discouraging traffic, staff member relief in batches, and preference card review for accuracy. During the six-week post-intervention period, there were no reported surgical site infections for orthopedic procedures, and the standardized infection ratio decreased from 1.75 to 0 in 10 weeks. Operating room traffic decreased after implementation by 46.9%. The number of door openings per minute decreased from 1.96 per minute to 1.04 per minute at the project's conclusion. Staff members' awareness of OR traffic increased.
