Background:
Routine manual cleaning and disinfection of the health care environment is often suboptimal. Residual contamination poses an infection risk, particularly for immunocompromised patients. This study evaluates the efficacy of dry hydrogen peroxide (DHP) on microbial surface contamination in a pediatric oncology intensive care unit.
Methods:
Surface samples from 5 high-touch and 2 low-touch surfaces were obtained for culture and adenosine triphosphate readings after manual cleaning on multiple days in 4 intensive care unit rooms, before and after DHP was deployed. Air samples were collected as well at the study site. Data outcomes were measured in terms of total colony-forming units for the cultures and relative light units for adenosine triphosphate.
Results:
The overall mean surface microbial burden was significantly reduced in the intervention group compared to the control group (mean 5.50 vs 11.77, P<.001). These reductions in colony-forming units were seen across all sampling sites in the intervention group. A reduction in the mean relative light units levels was also noted in the intervention group when compared to the control group (172.08 vs 225.83, P <.006). Reductions with the air samples were also noted (P = .139).
Conclusions:
Study demonstrates that DHP was effective in reducing microbial surface contamination and improves quality of environmental cleaning.
Insights
Dry hydrogen peroxide (DHP) significantly reduced microbial surface contamination in a pediatric oncology intensive care unit, improving environmental cleaning quality and reducing infection risks for vulnerable patients.
Area of Science:
- Healthcare-associated infections
- Environmental hygiene
- Infection control
Background:
- Manual cleaning of healthcare environments is often insufficient.
- Residual contamination presents infection risks, especially for immunocompromised individuals.
- This study assessed dry hydrogen peroxide (DHP) efficacy in a pediatric oncology intensive care unit.
Purpose of the Study:
- To evaluate the effectiveness of DHP in reducing microbial surface contamination.
- To assess the impact of DHP on environmental cleaning quality in a critical care setting.
Main Methods:
- Surface and air samples were collected from high-touch and low-touch surfaces.
- Adenosine triphosphate (ATP) and microbial cultures were used to measure contamination.
- DHP was applied after manual cleaning, with data collected before and after its deployment.
Main Results:
- DHP significantly reduced overall mean surface microbial burden (5.50 vs 11.77, P<.001).
- Reductions in colony-forming units and relative light units were observed across all sampling sites.
- A trend towards reduction in air samples was also noted (P=.139).
Conclusions:
- Dry hydrogen peroxide (DHP) is effective in reducing microbial surface contamination.
- DHP enhances the quality of environmental cleaning in healthcare settings.
- This method offers a promising approach to mitigate infection risks in critical care environments.
