Abstract: Objective: To explore the effects of the implementation of hospital infection management at digestive endoscopy center based on SHEL model. Methods: The purpose sampling method was adopted. Totally 85 staff members from Digestive Endoscopy Center of a tertiary grade A hospital in Jilin Province were included. The period from April 2020 to December 2020 was the control stage. The period from January 2021 to September 2021 was the intervention stage. We carried out the identification, analysis and treatment of nosocomial infection management issues in the department from the aspects of software, hardware, environment, liveware (SHEL mode). Nosocomial infection management quality index and patient satisfaction were compared between the two stages. Results: There were no nosocomial infection event related to endoscopic treatment in both stages. The frequency of occupational exposure in the intervention stage was 50% lower than that in the control stage. The quality indexes of staff training participation rate, occupational protection qualified rate, hand hygiene compliance rate, endoscope cleaning and disinfection qualified rate, environmental surface cleaning and disinfection rate, supervision and management rate and patient satisfaction in the intervention stage were significantly improved compared with the control stage (P<0.05). Conclusion: Nosocomial infection management based on SHEL model can effectively enhance the quality of hospital infection management in Digestive Endoscopy Center. It is worthy of clinical application to promote the safety of medical staff and patients and improve patients' medical experience.
