Hypothesis
Does scheduled dry fogging significantly reduce microbial loads in an open inpatient ward?
Conclusion
Dry fogging effectively reduces microbial loads in high-traffic healthcare environments.
Supporting Evidence
- Dry fogging significantly reduced airborne microbial loads over time.
- Surface microbial counts decreased in treated rooms, indicating effectiveness.
- Daily fogging showed better results compared to biweekly or no fogging.
Takeaway
Using a special fog to clean hospital rooms helps make them less dirty and safer for patients.
Methodology
Air and surface samples were collected from rooms with different fogging schedules over six months to evaluate microbial reduction.
Potential Biases
Potential sampling bias due to the dynamic nature of hospital environments.
Limitations
Surface contamination remained challenging due to frequent recontamination.
Participant Demographics
Patients in an inpatient ward at the University Hospital Bratislava.
