A New Metric
One of the ways antimicrobial products are misrepresented is when purveyors make claims such as “kills 99.9 percent of germs” while not providing the time required for this to occur.
Ideally, request the ratio of germ kill to allotted time resulting in a new metric or number.
Using this ratio, a user can create the Disinfection Performance Indicator (DPI).
This DPI metric, if accepted, would aid healthcare professionals in separating products that are very effective in a short time frame from those that are not.
