Investigation of the actual implementation of “post-sedation discharge briteria” and “time-out” immediately before procedure in endoscopy: A nationwide survey study in Japan

Abstract

Objectives

Post-sedation discharge criteria for outpatient endoscopy and time-out procedures immediately before endoscopic examinations are important for ensuring patient safety. This study used a web-based questionnaire to survey the implementation status and current situation of these practices in Japan in 2024.

Methods

A self-administered questionnaire was conducted from December 2023 to January 2024 using Google Forms. Participants were primarily from facilities involved in endoscopy study groups and readers of an endoscopy-specific e-newsletter. Additionally, medical staff from endoscopic centers across Japan were invited to participate in collaboration with the Japan Gastroenterological Endoscopy Technicians Society.

Results

A total of 1,495 valid responses (medical staff: 1197 [80%]; doctors: 298) were collected from 1168 facilities, after excluding duplicate responses. Among the participating facilities, 58% were general hospitals, 21% were clinics or health check-up centers, and 9% were university hospitals or national cancer centers. Post-sedation discharge criteria were implemented in 58% of facilities for esophagogastroduodenoscopy and 56% for colonoscopy, with the post-sedation recovery score used as the criterion in about half of these cases. Time-out procedures were implemented in 57% of the facilities for both esophagogastroduodenoscopy and colonoscopy. Items confirmed during time-out in more than half of the facilities included: patient's name, details of antithrombotic drugs, content of examination, drug allergies, underlying disease, date of birth, consent form, age, procedure start time, and patient's identification number.

Conclusion

The implementation rate of post-sedation discharge criteria and time-out procedures was found to be close to 60%, reflecting the real-world situation in Japan in 2024.
