An outbreak of Pseudomonas aeruginosa infection associated with contaminated urodynamic equipment
1Department of Urology, Kettering General Hospital, Kettering, Northants, NN16 8UZ, UK.
Abstract:
Seven patients developed Pseudomonas aeruginosa urinary tract infections following urodynamic studies, over a two-month period. One patient developed septicaemia and meningitis and died following rupture of a berry aneurysm. Two others required hospital admission for intravenous antibiotic treatment. Pseudomonas aeruginosa was isolated from a pressure dome which covered the pressure transducer of the urodynamic system used for assessing bladder pressure. The device packaging carried the symbol designating this as a 'single use' product, but as an economy measure, a local decision had been taken to change the device monthly.
Insights
Reusable urodynamic equipment led to Pseudomonas aeruginosa urinary tract infections in seven patients. One patient died from complications, highlighting risks associated with reusing single-use medical devices.
Area of Science:
- Urology
- Infectious Diseases
- Medical Device Safety
Background:
- Urodynamic studies are essential for diagnosing bladder dysfunction.
- Standard protocols emphasize sterile procedures and single-use equipment.
Observation:
- A cluster of seven Pseudomonas aeruginosa urinary tract infections (UTIs) occurred post-urodynamics.
- One patient experienced severe sepsis and meningitis, with a fatal outcome.
- Two patients required hospitalization for intravenous antibiotic therapy.
Findings:
- Pseudomonas aeruginosa was identified in the reusable pressure dome of the urodynamic system.
- The 'single-use' device was reused monthly as a cost-saving measure.
- This reuse practice created a reservoir for bacterial contamination.
Implications:
- Non-adherence to single-use protocols poses significant patient infection risks.
- Healthcare facilities must rigorously enforce single-use device policies.
- Economic pressures should not compromise patient safety and infection control standards.
