Optimising the reprocessing of endoscopes for patient safety

Abstract

Background: Annually, millions of endoscopies are performed around the globe. Endoscopes are reused countless times, and it is essential to reprocess them. Appropriate reprocessing maximises safety for patients undergoing endoscopy. Aim: This study aimed to assess practices before and after implementation of an evidence-based protocol in the endoscopy unit of a tertiary hospital in India. Methods: The protocol was communicated to healthcare professionals (HCPs) in a blended learning format. A validated reliable checklist was used by one group of HCPs to assess factors, practice and microbial growth before and after implementation of the protocol. Results: Most HCPs were male (71.42%) and nurses (57.14%). With no formal training, the practice scores were in an unacceptable range before the protocol and reached acceptable levels after. While the outer tip of endoscope showed no microbial growth, high concern organisms such as Escherichia coli were detected in suction channels. The protocol was effective in improving practice (t=-23.86; p<0.00) and reducing microbial growth (11.07; p<0.003), respectively. Conclusion: Facilities need to standardise guidelines of practice to ensure training, provide oversight and assess competency.
