Standard Operating Procedure: Surgical Safety and Verification

This Standard Operating Procedure (SOP) establishes the mandatory safety protocols required for all surgical interventions. Based on the World Health Organization (WHO) Surgical Safety Checklist framework, this document aims to reduce surgical morbidity and mortality by ensuring clear communication, patient identification, and systematic verification of site and procedure. Adherence to these steps is non-negotiable for all members of the perioperative team, including surgeons, anesthesiologists, and nursing staff.

Phase I: Sign-In (Before Induction of Anesthesia)

Confirm identity and preparedness before the patient enters the operating room or before anesthesia begins.

• Patient Verification: Confirm the patient’s identity, procedure, site, and consent via verbal confirmation and wristband verification.
• Site Marking: Ensure the surgical site is marked (e.g., “Yes” or surgeon initials) if applicable to the procedure.
• Anesthesia Safety Check: Confirm the anesthesia machine and medication check is complete.
• Pulse Oximetry: Ensure the pulse oximeter is on the patient and functioning.
• Risk Assessment: Assess patient for known allergies, difficult airway risk, and aspiration risk (including fasting status).
• Hemorrhage Risk: Assess for blood loss risk (>500ml or 7ml/kg in children) and ensure appropriate access/fluid availability.

Phase II: Time-Out (Before Skin Incision)

A formal pause involving all team members to ensure alignment and prevent “wrong-site/wrong-patient” errors.

• Introduction: Confirm all team members have introduced themselves by name and role.
• Team Consensus: Surgeon, anesthesiologist, and nurse verbally confirm:
  • Patient name and identity.
  • The exact procedure being performed.
  • The surgical site (left/right/specific anatomy).
• Antibiotic Prophylaxis: Verify that prophylactic antibiotics have been administered within the last 60 minutes.
• Essential Imaging: Confirm that all necessary diagnostic images for the procedure are displayed and verified in the OR.
• Equipment Readiness: Confirm all specialized equipment and implants required for the case are available and sterile.

Phase III: Sign-Out (Before Patient Leaves the OR)

Final review to ensure safety during the transition from the sterile field to recovery.

• Procedure Completion: Nurse verbally confirms the name of the procedure recorded.
• Instrument & Sponge Count: Nursing and technical staff perform a formal count of all needles, sponges, and instruments to ensure nothing is retained.
• Specimen Labeling: Ensure all specimens are labeled correctly, including the patient name and tissue origin.
• Equipment Issues: Identify any equipment malfunction or concerns that need to be addressed post-op.
• Recovery Plan: Surgeon, anesthesia professional, and nurse review key concerns for the patient’s recovery and postoperative management.

Pro Tips & Pitfalls

• Avoid the “Checklist Fatigue” Trap: Do not treat this as a robotic administrative burden. Treat the "Time-Out" as a critical safety barrier where anyone in the room has the authority to stop the procedure if they identify a discrepancy.
• The "Silent" Time-Out: A common pitfall is the "silent time-out," where the surgeon talks to themselves while the team remains disengaged. Ensure every team member stops their current task and focuses entirely on the verbal confirmation.
• Empower the Junior Staff: Encourage nurses and surgical technicians to speak up if they notice an inconsistency. Psychological safety in the OR is the greatest predictor of clinical safety.
• Incomplete Counts: Never rush the final instrument count. If a count is "off," do not close the patient until a formal search—including intraoperative imaging—is conducted.

Frequently Asked Questions

1. What should I do if a team member refuses to participate in the Time-Out? If a team member does not engage, the procedure must be paused. The surgeon or circulating nurse should explicitly state, "We cannot proceed until everyone has participated in the mandatory safety Time-Out." Patient safety protocols supersede interpersonal hierarchy.

2. Does the checklist apply to emergency surgeries? Yes. In an emergency, the checklist should be condensed to the most critical verification steps (Identity, Site, Procedure, and Antibiotics). Never bypass safety verification solely due to time pressure.

3. Who is responsible for keeping the checklist record? The circulating nurse is typically responsible for documenting the completion of the checklist in the electronic medical record (EMR), but the accountability for verifying the information is shared equally among the entire surgical team.
