UV Robot Fights C. Diff


It’s a challenge for busy hospitals around the country- get a sick patient into a room as fast as possible, but still ensure the room is sanitized and safe.

Now, new research shows using a special high-tech system is an effective way to reduce the risk of contracting C. diff, and other life-threatening infections.

Most of us probably don’t pay much attention, but there’s a lot of elbow grease that goes into disinfecting hospital patient rooms.

Now watch-as a state-of-the-art ultra-violet robot kills dangerous germs that regular cleaning can’t. The UV lights lock onto the DNA of organisms and wipe them out.

David Pegues, MD, Medical Director of Healthcare Epidemiology at the University of Pennsylvania Health System told Ivanhoe, “What we’re really doing by using this technology is removing germs that we can’t see that we would otherwise miss. Kill them, so that the next patient that is coming into that room isn’t exposed to a risk of catching or acquiring those germs.”

At the Hospital of the University of Pennsylvania after the work crew cleans, a robot is deployed in rooms of patients with compromised immune systems, like cancer patients. These patients may be more susceptible to infectious disease.

Dr. Pegues led a study of the UV cleaning method.  “We found the rates and the counts of infections with this C. difficile, or C. diff went down 25 percent,” he said.

The robot cleans the room in 16 minutes. Researchers say that doesn’t affect the turnaround time- which is a win for the hospital and also for sick patients waiting to get into a room, and leave without getting even sicker.

Dr. Pegues says his study showed the new cleaning interventions saved about $150,000 in annual direct medical costs by reducing the risk of C. diff infection. Every year in the United States, about 500,000 people contract C. diff while hospitalized and nearly 15,000 die as a direct result of that infection.

Clorox healthcare makes the ultra-violet robot that costs tens of thousands of dollars each, but the company negotiates the price with each individual hospital.


REPORT: MB #4040

BACKGROUND: New research from Penn Medicine infection control specialists found that ultraviolet (UV) robots helped reduce the rates of transmission of the common bacterial infection known as Clostridium difficile among cancer inpatients – mostly blood cancer patients, a group more vulnerable to hospital-acquired infections –  by 25 percent. The interventions also saved about $150,000 in annual direct medical costs.

ABOUT THE ROBOT: Clorox, a longtime manufacturer of manually applied disinfectants, made its move into the disinfection robot market in 2014, announcing plans to distribute and market UltraViolet Devices’ system. Keri Lestage, Clorox’s technical services group manager, said hospitals and health systems should use both manual disinfectants, as well as the extra layer of protection provided by the disinfection robot.

NEW TECHNOLOGY: Ultraviolet (UV) robots reduced the transmission rate of Clostridium difficile by 25% among hospitalized cancer patients, mostly among those with hematological malignancies, a group more vulnerable to hospital-acquired infections (HAIs). The interventions also saved about $150,000 in annual direct medical costs, Penn Medicine infection control specialists reported at IDWeek 2015.
