Ultra-V efficacy “insignificant” in 75% of terminal cleans – NHS study.

Hygiene Solutions own Corrado Gilbert, along with Royal Wolverhampton NHS Trust Infection Prevention Nurse Matthew Reid and others published the study below in the Journal of Infection Prevention.

Two observations:

From the table at the bottom of the Abstract, we see that the mean CFU drops from 15.71 to 2.92 as a result of the Ultra-V process. This is a 5 fold reduction. Hygiene Solutions website promises a log4 to log6 efficacy for Ultra-V, i.e. a 10,000 fold to 1,000,000 fold reduction. How do Hygiene Solutions account for the difference?

From “Results” we see that only 25% of the rooms had a statistically significant reduction in CFU. How do Hygiene Solutions explain the 75% of rooms that had no significant reduction in CFU?
