CHECKLIST-BASED INTERVENTIONS IN SURGERY: A NARRATIVE REVIEW OF THEIR IMPACT ON PERIOPERATIVE MORBIDITY, MORTALITY, AND PATIENT SAFETY
Abstract
ABSTRACT
Background: Checklist-based interventions have emerged as essential patient-safety strategies in modern surgical practice. Despite advancements in surgical techniques, anaesthesia, and perioperative care, preventable surgical complications and mortality continue to remain major global healthcare concerns. The World Health Organization (WHO) Surgical Safety Checklist was introduced to improve communication, teamwork, and standardisation of perioperative safety practices.
Objective: This review aims to critically evaluate the impact of checklist-based interventions on perioperative morbidity, mortality, surgical-site infections, and overall patient safety while identifying factors influencing successful implementation in surgical practice.
Methods: A comprehensive narrative review of published literature between 2008 and 2025 was conducted using electronic databases including PubMed, MEDLINE, Scopus, Embase, Google Scholar, and the Cochrane Library. Relevant studies evaluating surgical safety checklists, perioperative safety interventions, checklist compliance, communication, teamwork, and emerging technological developments were included and synthesised narratively.
Results: Current evidence demonstrates that checklist-based interventions significantly improve perioperative patient safety through reductions in postoperative complications, surgical-site infections, anaesthesia-related adverse events, and perioperative mortality. Improved communication, multidisciplinary teamwork, procedural standardisation, and prevention of omission-related errors were identified as major contributors to improved outcomes. However, checklist effectiveness varies depending on implementation quality, institutional safety culture, staff training, leadership support, and behavioural engagement. Emerging developments including digital surgical checklists, artificial intelligence-assisted perioperative systems, and specialty-specific checklist adaptations may further strengthen future perioperative safety practices.
Conclusion: Checklist-based interventions remain valuable and cost-effective perioperative safety tools capable of improving surgical outcomes and reducing preventable patient harm. Sustainable effectiveness depends on meaningful multidisciplinary participation, continuous staff education, institutional commitment, and integration of checklist practices within broader patient-safety frameworks.
