High Number of Door Openings Increases the Bacterial Load of the Operating Room.

ABSTRACT: Background: Operating room (OR) traffic and door openings have emerged as potential modifiable risk factors for the development of surgical site infections. Methods: This study compared the microbial load of a Control OR without traffic versus a Simulated OR with the traffic in a typical orthopedic surgery case. Air particle counts and colony forming units (CFUs) were measured. A novel iOS app was developed to provide real-time door counts. Results: There were 1,862 particles >5.0 mcm in the Simulated OR compared with 56 in the Control OR. The CFUs from plates in the Simulated OR ranged from 4-22 (on brain heart infusion [BHI] agar), 2-266 (on mannitol salt agar [MSA]), and 1-19 (on Pseudomonas isolation agar [PIA]), while all plates in the
