In this episode of The Surgical Checklist, we explore the World Health Organization surgical safety checklist and the Five Steps to Safer Surgery from a practical, real-world perspective. Moving beyond theory, we discuss how the checklist is actually used in theatre, where it works well, and where it can break down under pressure. With a focus on the ODP role, this episode highlights how communication, teamwork, and human factors influence patient safety, and why meaningful engagement with the checklist matters far more than simply completing it.
