Do not open the doors of the operating room during the surgical activity, except where necessary for the passage of patients, staff and equipment.
The prevention strategies for Surgical Site Infections (SSI) are focused on three areas: patient, surgical technique and environmental conditions of the operating room. Among the latter, it is important to refer to the air quality (particle and microbial contamination, temperature, humidity, etc.). According to previous studies, the opening of the doors can compromise the air quality by changing the microclimate of the operating room and by causing an increase in the microbial air contamination. Particularly, a multicenter study conducted by GISIO-SItI highlighted a positive correlation between the number of door openings and the values of the Microbial Air Index (IMA), during hip and knee arthroplasty surgeries. Furthermore, the opening of the doors affects the performance of surgical activity, favouring the distraction of the operators and the related risk of errors. The reasons for the opening of the doors are often inappropriate, suggesting the need for corrective actions and educational interventions aimed at reducing their frequency.
