What is the purpose of a perioperative 'time-out' and who participates?

• A. To verify patient identity, surgical site, procedure, and consent; all members—surgeon, anesthesia provider, scrub, circulating nurse—participate.
• B. To finalize postoperative billing; only administrative staff.
• C. To designate equipment suppliers; nurses only.
• D. To review nonessential details of the case; surgeon only.

Answer: (A)

The purpose of a perioperative time-out is to prevent wrong-site, wrong-procedure, and wrong-patient errors by confirming critical information right before incision. It’s a standardized pause where the team verifies the patient’s identity, the correct surgical site, the planned procedure, and that informed consent is in place. Everyone on the team participates: the surgeon confirms the site and procedure, the anesthesia provider reviews who the patient is, allergies, airway considerations, and risk factors, the scrub tech ensures the sterile field and that the correct instruments are available, and the circulating nurse coordinates imaging and implants and leads documentation and counts. This collaborative check promotes clear, shared understanding and communication, in line with universal safety protocols. Descriptions focused on postoperative billing, designating equipment suppliers, or reviewing nonessential details by a single person don’t meet the safety purpose of the time-out.
