Hospital Acquired Infections

Ensuring patient health, one test at a time.

Hospital Acquired Infections (HAI’s), otherwise known as Healthcare-Associated Infections, are infections patients get while receiving medical treatment in healthcare facilities, such as a hospital, ambulatory surgical center, nursing home, etc. HAI’s present a major, but largely preventable, threat to patient safety. According to the CDC and the New England Journal of Medicine, in 2011 there were an estimated 722,000 instances of Hospital Acquired Infections in U.S. acute care hospitals. Of these, around 75,000 patients succumbed to these infections.  While this figure is on the decline, Hardy Diagnostics shares the sentiment that anything above zero is too many!

Hardy Diagnostics is doing our part to help prevent further instances of HAI’s with a range of products specifically designed to detect harmful bacteria before they infect a patient.
