Abstract:
A small epidemic of Pseudomonas cepacia infection in an intensive care nursery was associated with contaminated, distilled water. This appeared to have occurred because of a leak in the distiller, contaminating its effluent. The distilled water was not subsequently sterilized, nor were the bottles used to distribute it. The epidemic was promptly terminated by substitution of sterile, distilled water distributed in sterile containers. Both professional and nonprofessional hospital personnel failed to oversee the appropriateness of handling of patient care materials.
Insights
A Pseudomonas cepacia outbreak in an intensive care nursery was linked to contaminated distilled water. Sterilizing water and containers stopped the infection, highlighting the need for better material handling oversight.
Area of Science:
- Infectious Diseases
- Hospital Epidemiology
- Public Health
Background:
- Pseudomonas cepacia infections pose a significant risk in intensive care settings.
- Contaminated water sources can lead to nosocomial outbreaks.
- Inadequate sterilization protocols can compromise patient safety.
Purpose of the Study:
- To investigate the cause of a Pseudomonas cepacia outbreak in an intensive care nursery.
- To identify the source of contamination and transmission routes.
- To recommend measures for preventing future outbreaks.
Main Methods:
- Epidemiological investigation of the outbreak.
- Microbiological analysis of water samples and distribution containers.
- Review of hospital protocols for water handling and sterilization.
Main Results:
- A leak in the water distiller led to contamination of distilled water.
- The contaminated distilled water was distributed in non-sterile containers.
- Substitution with sterile water and containers eradicated the outbreak.
Conclusions:
- Contaminated distilled water was the source of the Pseudomonas cepacia epidemic.
- Failure in sterilization and handling of patient care materials contributed to the outbreak.
- Strict adherence to sterilization protocols and oversight are crucial for preventing hospital-acquired infections.
