Abstrakt: Introduction: Infections following orthopedic surgery are rare but difficult to treat. Among the prevention measures reviewed during the Musculoskeletal Infection Society's (MSIS) 2023 international consensus meeting, the only strategy to obtain 100% agreement was the control of traffic in and out of the operating room (OR). Although this recommendation makes good sense, to our knowledge, it has not been previously investigated in a comparative study. We, therefore, conducted a prospective, observational, before-and-after study of the implementation of an informational sign designed to limit traffic in and out of the OR to (1) determine its impact on door openings and the number of people present during orthopedic surgery and (2) assess the risk of surgical site infection after the institution of this sign.
Hypothesis: This type of sign reduces the number of door openings.
Materials and Methods: This prospective, observational study included all patients operated on in one of our ORs over a 6-week period. The number of entrances and exits from the OR and how long the doors were kept open were recorded during the entire study period. After 3 weeks, an informational sign was posted on the OR doors warning people that unnecessary traffic in and out of the OR increases the risk of infection. During this period, we also recorded the type of procedure, operative time, the number of people in the OR at the time of the incision, and the number of entrances and exits. Patients underwent a follow-up at 2 years to check for postoperative infection. The primary endpoint was the number of OR door openings, and the secondary endpoint was the number of infections at 2 years postoperatively.
Results: The 2 groups (before and after the implementation of the sign) were homogeneous. The average total number of door openings for all ORs was 28.9±19.6 [2-90]. In the no sign group, it was 33.3±20.9 [3-90], and in the sign group, it was 21.0±14.7 [2-50] (p=0.011). The maximum number of people in the OR at one time was 8.32±1.84 [4-12] in the no sign group and 8.44±1.98 [5-12] in the sign group (p=0.8). There were 3 postoperative infections at the 2-year follow-up, all occurring in the no sign group. The infection rate was 6.4% (3/47) in the no sign group versus 0% (0/25) in the sign group (p=0.197).
Discussion: Our prospective study demonstrated a simple strategy to reduce the number of entrances and exits, the number of people in the OR, and potentially the risk of surgery-related infection. Another larger-scale study is needed to assess the exact impact of this type of sign, particularly on the risk of infection.
Level of Evidence: III; prospective non-randomized comparative study.
