Endoscopic retrograde cholangio-pancreatography: related nosocomial infections
Abstract:
The flexible endoscopes of a gastroenterology department were microbiologically examined after one patient developed a possible nosocomial infection. The endoscopes were found to be contaminated by pseudomonas species. An appropriate cleaning regime was developed and the initial difficulties in sterilising the instruments are described. The medical records of all ERCPed patients for the one and half years prior to and the half year after the monitoring exercise were examined. It was found that approximately 50 percent of patients examined in the half year prior to the introduction of endoscopic monitoring had infections with Pseudomonas species.
Insights
Flexible endoscopes in a gastroenterology department were found to be contaminated with pseudomonas species, leading to patient infections. A new cleaning protocol was implemented to address this significant nosocomial infection risk.
Area of Science:
- Gastroenterology
- Infectious Diseases
- Microbiology
Background:
- Flexible endoscopes are critical for gastrointestinal diagnostics and procedures.
- Nosocomial infections pose a significant risk in healthcare settings.
- Pseudomonas species are common opportunistic pathogens.
Purpose of the Study:
- To investigate the microbiological contamination of flexible endoscopes.
- To identify the source of a possible nosocomial infection.
- To evaluate the effectiveness of a new cleaning and sterilization protocol.
Main Methods:
- Microbiological examination of flexible endoscopes.
- Review of medical records for patients undergoing Endoscopic Retrograde Cholangiopancreatography (ERCP).
- Development and implementation of an enhanced instrument cleaning regime.
Main Results:
- Flexible endoscopes were found to be contaminated with Pseudomonas species.
- Approximately 50% of patients prior to monitoring had Pseudomonas infections.
- Initial difficulties were encountered in sterilizing the endoscopes.
Conclusions:
- Contaminated flexible endoscopes can lead to significant rates of Pseudomonas infections in patients.
- Effective cleaning and sterilization protocols are crucial for preventing nosocomial infections.
- Endoscopic monitoring is essential for ensuring instrument safety.
