Who should participate in the preoperative time-out to prevent wrong-site surgery?

• A. The patient and surgeon only
• B. The entire surgical team
• C. The janitorial staff
• D. The operating room vendor

Answer: (B)

The main concept is that the preoperative time-out is a team-based safety pause used to verify critical information before any incision is made. The most effective way to prevent wrong-site surgery is to have the entire surgical team participate in this check, not just the surgeon and patient.

When everyone from the surgeon, anesthesia provider, circulating nurse, scrub tech, and other present team members participates, there are multiple eyes and voices confirming details such as the patient’s identity, the planned procedure, the exact site and laterality, whether any implants or devices are involved, allergies, and whether antibiotics or other perioperative plans are in place. This shared verification creates a safety net: if any member notices a discrepancy or potential issue, they can speak up and halt proceeding. The patient can contribute when feasible, reinforcing consent and accuracy, but the process relies on the whole team, since issues can arise in areas beyond the surgeon’s direct view.

janitorial staff or outside vendors aren’t part of this verification process and shouldn’t be relied upon for safety checks during the time-out, as they don’t routinely participate in the surgical safety verification and could introduce distractions or confusion.

So, the entire surgical team participating in the time-out ensures comprehensive, collaborative verification right before incision, tying into the goal of preventing wrong-site or other sentinel errors.
