Background : Reductions in perioperative surgical site infections are obtained by a multifaceted approach including patient decolonization, vascular care, hand hygiene, and environmental cleaning Associated surveillance of S aureus transmission quantifies the effectiveness of these basic measures to prevent transmission of pathogenic bacteria and viruses to patients and clinicians, including Coronavirus Disease 2019 (COVID-19) To measure transmission, the observational units are pairs of successive surgical cases in the same operating room on the same day We measured sampling times for inexperienced and experienced personnel Methods : OR PathTrac kits included 6 samples collected before the start of surgery and 7 after surgery The time for consent also was recorded We obtained 1677 measurements of time among 132 cases Results : Sampling times were not significantly affected by technician's experience, type of anesthetic, or patient's American Society of Anesthesiologists’ Physical Status Sampling times before the start of surgery averaged less than 5 minutes (3 39 minutes [SE 0 23], P &lt; 0 0001) Sampling times after surgery took approximately 5 minutes (4 39 [SE 0 25], P = 0 015) Total sampling times averaged less than 10 minutes without consent (7 79 [SE 0 50], P &lt; 0 0001), and approximately 10 minutes with consent (10 22 [0 56], P = 0 70) Conclusions : For routine use of monitoring S aureus transmission, when done by personnel already present in the operating rooms of the cases, the personnel time budget can be 10 minutes per case
Sample times for surveillance of S. aureus transmission to monitor effectiveness and provide feedback on intraoperative infection control
