Hospitals at Risk for Waterborne Diseases

Evan Sweeney, for HealthLeaders Media, August 2, 2010

Not only can this affect compliance with Joint Commission accreditation, failure to adhere to these standards can also work against you in the court of law, particularly if an outbreak affects numerous people. 

“The environment of care is not a guideline, it’s a standard—a standard that carries tremendously much more legal weight than a guideline,” Keane says. 

In February 2009 and March 2010, a waterfall-type fountain in the lobby of a Wisconsin hospital caused an outbreak of Legionnaires’ disease in eight people.

The state health department released recommendations on decorative waterfalls, but the outbreak remains fresh in the minds of Joint Commission surveyors, says Peggy Prinz-Luebbert, MS, MT(ASCP), CIC, CHSP, owner of Healthcare Interventions, Inc., in Omaha, NE.

“Especially since we’ve had outbreaks now, if [a surveyor] sees a waterfall, they are going to want to see what kind of maintenance you do on it, what kind of testing you do on it, and if you’ve had problems, how you’ve responded to them,” Luebbert says.

Testing potable water
Even if you don’t have water structures in your hospital, you still need to be aware of the risks in your potable water system. 

“With potable outbreaks, you don’t get a bunch of people getting sick all at the same time, so if hospitals aren’t testing for legionella—which most of them don’t do—you may not find it because legionella is a type of pneumonia,” Keane says. Hospitals are required to keep their hot water systems at 120ºF, he adds, which is a prime temperature for growing legionella. 

Additionally, the guidelines for new hospitals create a much higher risk for waterborne illnesses, says Keane, who has been in hospitals with showers in every room, but the showers had never been used. Many of those showers also had shower hoses, which is a huge breeder of bacteria because of stagnant water.

“In new hospitals you have one person in a room, a sink as soon as you walk in the room for the doctor or nurse to wash their hands, and another sink in the bathroom,” Keane says. “And on top of that, you have waterless hand cleaner so nobody uses the sink. New hospitals have four times as many sinks per patient as older hospitals, and they are almost all stagnant because people are using the waterless hand cleaners.”
