About this Content

Aims

To enhance environmental hygiene using Germicidal UVC light for secondary disinfection to reduce HAIs.

Background

Manual cleaning processes have limitations, including missed areas and long chemical contact times.

Methods

Introduced UVC machines for targeted disinfection; tested effectiveness with photovoltaics stickers on high-touch surfaces.

Results

Achieved 4-log reduction in bioburden; 13 of 14 test points showed effectiveness, except areas obstructed from UV exposure.

Conclusion

UVC technology significantly enhances cleaning effectiveness, improves environmental hygiene, and reduces HAIs.

Lessons Learnt

Proper training and strategic machine placement are critical for successful implementation.

Additional Information

Recognized for improving patient safety through advanced disinfection methods.
