INTRODUCTION: Based on the Guidelines for Surgical Recommendations, the WHO has developed a 19-item operating room safety checklist to support surgical teams, ensure quality and safety, and prevent mortality and postoperative complications The checklist includes three phases (Sign In, Time Out, Sign Out), 20 items with checks to be performed during the surgery, and the corresponding boxes to be checked after the checks have been completed. It is recommended to appoint a checklist coordinator among the team members who is responsible for reviewing the checks by each member of the operating team, and only after the checks have been established. I developed the questionnaire following the WHO guidelines, specifically the "Guidelines for Surgery" document, which was drafted by the association to present the operating room checklist for patient and staff safety. Objective: The purpose of this survey is purely informative, to obtain a state-of-the-art overview and to compare it with my own work environment. Methods: Taking into account the key points highlighted by the WHO, I developed a total of eight questions. The questions addressed the importance of implementing the checklist, the checklist phases in general, the checklist coordinator, the role of the checklist coordinator, adapting the checklist to one's work environment, the sign-in phase, the time-out phase, and the sign-out phase. Results: As confirmed by the literature, the introduction of checklists and the use of clinical protocols, if used responsibly and effectively, significantly reduce clinical risks and can become an important prevention tool. Conclusions: After analyzing the responses, it can be deduced that the checklist is completed correctly, carefully, and scrupulously in most contexts. The percentage of correct answers consistently exceeds the percentage of incorrect ones. I believe the importance of the checklist as a tool for patient and healthcare worker safety is well understood. These data are
