ABSTRACT

OBJECTIVE@#To investigate the situation regarding the cleaning and sterilization of endonasal endoscopes in department of otolaryngology in Hunan Province, and to provide strategy for improving the level of sterilization and management of endonasal endoscopes.
@*METHODS@#A total of 100 medical institutions were investigated by spot assessment, check and sampling. Data was analyzed by multivariate analysis.
@*RESULTS@#The qualified rate of rules and regulations for endoscopy was 28.8% in the second-class hospitals and 45% in the top-class hospitals. The qualified rate of environment for endoscopy cleaning and sterilization was 36.3% in the second-class hospitals and 85% in the top-class hospitals. The main problems include lack of independent disinfection room, the space not large enough, and/or lack of ventilation system. The qualified rate of bacterial detection for post-sterilized endoscopes and biopsy forceps was 93.8% in the second-class hospitals and 95.0% in the top-class hospitals, and the main pathogenic bacteria was gram-positive cocci and gram-negative bacilli. The multivariate analysis showed that the influencial factors for endoscope cleaning and disinfection are as follows staffs responsible for the cleaning and sterilization of otolaryngology endoscopes, the standard for cleaning and disinfection process, and the frequency of endoscope use.
@*CONCLUSION@#The present situation of cleaning and sterilization for otolaryngology endoscopes is better in the top-class hospitals than that in the second-class hospitals. The sterilization and management of otolaryngology endoscopy are needed to be improved, and the staff training is needed, especially in the primary hospitals.
