Introduced in 2008 as part of the World Health Organization's (WHO) "Safe Surgery Saves Lives" initiative, the Surgical Safety Checklist is a critical tool for improving patient outcomes. Inspired by aviation safety protocols, this checklist ensures surgical teams consistently perform essential safety steps, thereby significantly reducing surgical errors and patient harm. Its 19-item format is designed for broad applicability across diverse surgical settings.
The Three Phases of the Safer Surgery Checklist
Operating room procedures are divided into three key phases by the WHO surgical safety checklist, each requiring a team pause to confirm specific actions.
Phase 1: Sign In (Before Induction of Anesthesia)
This phase occurs before anesthesia is administered, with the patient participating. It involves verifying patient identity, the surgical site, procedure, and consent. The surgical site marking is also checked, along with anesthesia equipment, medications, and the pulse oximeter. The team also reviews patient allergies and risks of airway difficulty, aspiration, and significant blood loss.
Phase 2: Time Out (Before Skin Incision)
Just before the incision, the entire surgical team pauses for confirmation. Team members introduce themselves by name and role. They reconfirm the patient's identity, the procedure, and the incision site. The surgeon outlines critical steps and expected duration and blood loss, while the anesthesiologist highlights patient-specific concerns. Sterility of instruments and equipment is confirmed by the nursing team. Administration of antibiotic prophylaxis within 60 minutes and display of essential imaging are also verified.
Phase 3: Sign Out (Before Patient Leaves the Operating Room)
This final phase, before the patient leaves the OR, focuses on documentation and transition of care. The nurse confirms the procedure performed. The team verifies the count of sponges, sharps, and instruments. Any specimens are correctly labeled and verified. Equipment issues are discussed, and the postoperative plan is reviewed.
The Impact and Effectiveness of the Checklist
The surgical safety checklist has a documented positive impact on patient outcomes and safety culture.
- Reduced Complications: A study showed significant reductions in major complications and mortality rates following checklist implementation.
- Improved Communication and Teamwork: Deliberate pauses enhance collaboration and problem-solving.
- Standardization of Care: The checklist promotes consistent safety practices.
- Enhanced Safety Culture: Regular checklist use fosters a stronger culture of patient safety.
Comparison of Different Surgical Checklists
Various surgical checklists exist with different scopes. The WHO Surgical Safety Checklist primarily focuses on the three OR phases. The Surgical Patient Safety System (SURPASS) checklist covers the entire perioperative period. Other checklists often focus on specific issues like preventing wrong-site surgery.
| Feature | WHO Surgical Safety Checklist (SSC) | Surgical Patient Safety System (SURPASS) Checklist | Other Checklists (e.g., Joint Commission) |
|---|---|---|---|
| Scope | Primarily focuses on the three critical phases within the operating room (OR). | Encompasses the entire perioperative period, from patient admission to hospital discharge. | Often focus on specific aspects, such as the Universal Protocol for preventing wrong-site surgery. |
| Key Focus Areas | Patient identification, site marking, anesthesia checks, sterility, instrument counts, and communication. | Broader checks including overall patient care coordination outside the OR. | Confirms correct patient, procedure, and site. |
| Implementation | Widely adopted globally, although implementation fidelity can vary. | Used in some facilities, particularly in the Netherlands where it was developed. | Mandated for accredited hospitals in some regions. |
| Strengths | Simplicity, global endorsement, proven effectiveness in reducing OR complications and mortality. | Addresses a wider range of potential errors that can occur both inside and outside the OR. | Simple, focused, and directly addresses the high-risk issue of wrong-site surgery. |
Conclusion: The Checkbox That Saves Lives
The surgical safety checklist is an evidence-based tool that has improved surgical safety. It enhances communication and standardizes safety steps, leading to reduced complications and mortality. Effective implementation is key, and the checklist remains a vital part of modern patient safety efforts.
