Abstract:
Clostridium difficile was recovered from 33 (34%) of 98 rooms of patients who were excretors compared with 36 (49%) of 73 rooms of patients with active infection. Not all laboratory algorithms can distinguish between these 2 groups, yet both may be a significant source for ongoing transmission.
Insights
Clostridium difficile was found in patient rooms, with higher rates in rooms of patients with active infections. Both patient groups may contribute to Clostridium difficile transmission.
Area of Science:
- Microbiology
- Infectious Diseases
- Environmental Hygiene
Background:
- Clostridium difficile is a significant cause of healthcare-associated infections.
- Understanding environmental contamination is crucial for infection control.
- Distinguishing between patient shedding and active infection sources is important.
Purpose of the Study:
- To assess the prevalence of Clostridium difficile in patient rooms.
- To compare environmental contamination levels between patients excreting C. difficile and those with active infections.
- To evaluate the implications for transmission.
Main Methods:
- Environmental sampling of patient rooms.
- Laboratory detection of Clostridium difficile.
- Comparison of recovery rates based on patient clinical status.
Main Results:
- Clostridium difficile was recovered from 34% of rooms of excretor patients (33/98).
- Clostridium difficile was recovered from 49% of rooms of patients with active infections (36/73).
- Higher recovery rates were observed in rooms of patients with active infections.
Conclusions:
- Clostridium difficile contamination is prevalent in patient rooms.
- Rooms of patients with active C. difficile infections show higher contamination.
- Both patient groups represent potential sources for Clostridium difficile transmission, necessitating effective infection control measures.

HAIs significantly increase the cost of health care. Extended stays in healthcare institutions, increased disability, increased costs of medications, including specialized antibiotics, and prolonged recovery times add to the patient's expenses and the healthcare institution and funding bodies.

Cleaning, Sterilization, and Disinfection
Cleaning
The cleaning process usually involves using water with detergents or enzymatic cleaner and removing foreign material from objects and surfaces, including organic material such as body fluids or inorganic material like soil. Cleaning is performed before high-level disinfection and sterilization because foreign materials on the cover of the devices interfere with process...
