Background and objective: The WHO launched the "Safe Surgery Saves Lives" campaign in 2008 to improve patient safety during surgery. The campaign includes the use of the WHO Surgical Safety Checklist, which has been proven effective in reducing complications and mortality rates in several studies. This article discusses a clinical audit at a tertiary healthcare facility that assesses compliance with all three components of the checklist to minimize errors and improve safety standards.Materials and methods: This prospective, observational, closed-loop clinical audit study was conducted at Hayatabad Medical Complex, a tertiary care public sector hospital located in Peshawar, Pakistan. The audit aimed to assess compliance with the WHO Surgical Safety Checklist. The first phase of the audit cycle commenced on October 5, 2022, and involved collecting data from 91 surgical cases in randomly selected operating rooms. Following the completion of the first phase on December 13, 2022, an educational intervention was then conducted on December 15 to underscore the significance of adhering to the checklist, and the second phase of data collection began the following day, ending on February 22, 2023. The results were analyzed using SPSS Statistics version 27.0.Results: The first phase of the audit showed that there was poor compliance with the latter two parts of the checklist. Certain components of the WHO Surgical Safety Checklist were well-complied with, including patient identity confirmation (95.6%), obtaining informed consent (94.5%), and counting of sponges and instruments (95.6%), while the lowest compliance rates were in recording allergies (26.3%), assessing blood loss risk (15.3%), introducing team members (62.6%), and inquiring about patient recovery concerns (64.8%, 34%, and 20.8% for surgeons, anesthetists, and nurses, respectively). In the second phase, after an educational intervention, compliance with the checklist improved significantly, particularly for those components with low compliance rates in the first phase, marking recording allergies (89.0%), introducing team members 91.2%), and inquiring about patient recovery concerns (79.1%, 73.6%, and 70.3% for surgeons, anesthetists, and nurses, respectively).Conclusion: The study showed that education is a critical factor in improving compliance with the WHO Surgical Safety Checklist. The study suggests that overcoming the obstacles to implementing the checklist requires a collaborative environment and effective instruction. It emphasizes the importance of adhering to the checklist in all surgical settings.
