Fewer people means fewer door openings. improves product management. lessens distractions. improves logistical efficiencies.


Outsourced implant management services can help promote good traffic control practices in the OR by reducing the number of people involved in the management of products for surgery.

SimplOR clients reduce rep traffic 87% or more

Surgical site infections (SSI’s) cause significant morbidity and mortality in the postoperative period. 

Door openings increase in direct proportion to case length, but have an exponential relationship with the number of persons in the operating room, and disrupt its filtered atmosphere, increasing contamination above the wound.

In one study published in the journal Orthopedics (Study senior author Stephen Belkoff, Ph.D., M.P.H., an associate professor in the Johns Hopkins University School of Medicine’s Department of Orthopaedic Surgery and the Director of the International Center for Orthopaedic Advancement), investigators tracked the number and length of door openings during nearly 200 knee and hip arthroplasty surgeries performed at Johns Hopkins Bayview Medical Center over three months. Of the 100 knee arthroplasties and 91 hip arthroplasties performed during the study time, doors opened on average every 2.5 minutes. That’s a door-open time of 9.6 minutes per average case, which lasted about an hour and a half, and it accounted for about 9 percent of the total cut-to-close time, the study’s author, says. In 77 of the 191 cases, doors were open long enough to compromise the ORs’ positive pressure systems, allowing air from surrounding corridors to flow inside. 

Beyond potential contamination from airflow, excessive foot traffic could suggest distraction among OR staff and logistical or personnel management inefficiencies.

As stated in “The Effect of Traffic Patterns in the OR on Surgical Site Infections” Pryor, Flavia RN  BSN, CNOR; Messmer, Patricia R. RN PhD, C, “A study was conducted to explore the effect of traffic patterns, specifically the number of people in the OR, on the incidence of surgical site infections. Research analyzed 2,864 clean surgical procedures performed in an academic medical center. A rising trend in SSI’s was observed as the number of people in the OR increased.”
