Objectives
The aim of this study is to evaluate the quality of disinfection of endoscopes at Brest hospital over a period from 2007 to 2009.
Patients and methods
Retrospective study of microbiological investigations of endoscopes done at Brest hospital from 2007 to 2009. The interpretation of the microbiological investigations is based on the recommendations of the Comité technique national des infections nosocomiales et infections liées aux soins (CTINILS) of 2007.
Results
Most of the controls realized over the period deal with gastroenterological endoscopes (63.4 % ) and bronchial endoscopes (21.8 % ). Most of the controls (66.8 % ) are conformed to the target level. Only 26.7 % of the controls get the level of action. Globally, the rate of level of action significantly increases (p = 0.004) from 2007 (21.2 % ) to 2009 (35.6 % ). This increase is relatively important in gastroenterology endoscopy (46.8 % in 2009 versus 24.1 % in 2007) whereas the rate decreases in bronchial endoscopy (14.8 % in 2009 versus 25.9 % in 2007). In gastroenterological endoscopy, rates vary with the type of endoscopes and the context of controls, but there is no significant difference between manual disinfection and automated disinfection. The most frequent germ found in gastroenterological and bronchial endoscopies is Pseudomonas aeruginosa.
Conclusion
Our results show that it is very difficult to insure a perfect disinfection of endoscopes. Difficulties met are certainly related with the complexity of the endoscopes and of the techniques of disinfection. Infections of patients are very infrequent in endoscopy, which takes the question of the pertinence of the threshold used for microbiological investigations.
