Summary
Underwater-massage tubs in hospitals frequently harbor microorganisms, posing infection risks. Investigations revealed high microbial counts, with Pseudomonas aeruginosa found in about 70% of tubs, necessitating improved disinfection protocols.
Area of Science:
- Microbiology
- Hospital Hygiene
- Public Health
Background:
- Underwater-massage tubs can serve as reservoirs for microbial contamination in healthcare settings.
- Previous anecdotal evidence suggested potential contamination issues within these specific hygiene devices.
Purpose of the Study:
- To assess the microbial contamination levels of underwater-massage tubs in a hospital setting.
- To evaluate compliance with German DIN standard 19,643 for disinfection of water systems.
Main Methods:
- Conducted microbiological investigations on 41 underwater-massage tubs.
- Applied German DIN standard 19,643 for sample collection and analysis.
- Identified specific bacterial contaminants, including Pseudomonas aeruginosa.
Main Results:
- A high prevalence of microbial contamination was detected in the majority of investigated tubs.
- Pseudomonas aeruginosa, a pathogen associated with infection risk, was identified in approximately 70% of the tubs.
- Contamination was linked to tub pump design and inconsistent cleaning/disinfection procedures.
Conclusions:
- Current cleaning and disinfection practices for underwater-massage tubs are often inadequate.
- The design of certain tub pumps may contribute to microbial proliferation.
- There is an urgent need for standardized, reliable disinfection procedures to mitigate infection risks associated with these devices.
