From Mayo Clinic to UPMC to UCLA, today’s hospitals are finding that traditional sterilization methods are often ineffective --even lethal, and are reverting to EtO sterilization, effectively putting an end to nosocomial outbreaks.
Why is EtO still the gold standard for low temperature sterilization?
The Superbug Era
Over 75,000 patients will die this year in the U.S. from nosocomial infections (Source: CDC historical data). In the era of CRE and other superbugs, the sterilization landscape has changed forever. The FDA has stepped in to bring EtO sterilization back to the forefront. Notably, they now recommend EtO for endoscopy sterilization.
Hospitals are recognizing that EtO is currently the only low temperature sterilization sterilant that succeeds at erradicating hospital associated infection outbreaks and reverting to EtO, in particular in regards to endoscopy.

Although not all HAI deaths are avoidable using an EtO sterilization system, they can certainly be substantially reduced, as recent history proves.
Reuters highlights that, contrary to what the available CDC data suggests, the overall incidence of HAI deaths over the 2003-2014 span have nearly doubled. We are seeing unprecedented levels of HAI infection, often underreported.
