Robots sanitize operating rooms better than humans

A peer-review study in the American J of Infection Control revealed a 46% drop in surgical site infections after Lowell General Hospital in Massachusetts started using disinfecting robots in its operating rooms (2013-14).

These machines use pulsed xenon ultraviolet light to clean the ORs each night. The process takes about 10 minutes.

First, the staff used their usual chemicals to disinfect, then the robots threw the ultraviolet into every nook and cranny.

Hospital-acquired infections are a leading cause of death--75,000 to 90,000 a year.

Using the ultraviolet was thought to have prevented 23 infections--and saved one life (infections claim the lives of 3% of those who get them). This could have saved as much as $478,000.

Xenex Disinfection Services, a San Antonio company whose robot is shown here, said this hospital was the seventh to report reduced infection rates from the robots.

Sure sounds promising--bring them on.
