Do not open the doors of the operating room during the surgical activity, except where necessary for the passage of patients, staff and equipment.

Surgical site infection prevention strategies mainly focus on three areas: the patient, the surgical technique and environmental conditions in the operating room, including air quality (temperature, humidity, particle and microbial count, etc.). Unjustified door opening may result into poor air quality and change in the microclimate of the operating room and thus lead to an increase in microbial contamination of air and risk of surgical site infection. Motivations underlying door opening are often completely inappropriate and/or non-essential to the intervention, then subject to corrective actions and targeted education campaigns to reduce their frequency. Moreover, this practice interferes with the flow of surgical activity, favouring the distraction of health professionals with consequent risks of errors. The reduced frequency of door opening thus contributes to better patient care safety.
