Two patients at Ochsner Medical Center on Jefferson Highway in New Orleans were diagnosed with Legionnaires’ disease. No other information was released.
Ochsner Health System officials reported two patients at Ochsner Medical Center in New Orleans were diagnosed with Legionnaires’ disease, also known as Legionella pneumonia.
No information was released on the condition of the patients, whether they were diagnosed at the Jefferson Highway hospital, still admitted to the hospital, or when the illnesses were diagnosed.
“Preliminary environmental test results detected Legionella bacteria at OMC–Jefferson Highway,” according to a statement released by Ochsner on its website. “The cultures obtained lead us to believe the bacteria were from isolated fixtures and not in our water system.”
Ochsner Medical Center outbreak: stagnant water?
A person contracts Legionella bacteria by inhaling microscopic water droplets in the form of mist or vapor. The bacteria, which thrive in warm water, are found primarily in human-made environments, such as:
- water systems of large buildings (hospitals, nursing homes, hotels, etc.)
- large plumbing systems
- hot-water heaters and tanks
- bathroom showers and faucets
- physical-therapy equipment
- whirlpools and hot tubs
- swimming pools
- air-conditioning system cooling towers
- mist machines and hand-held sprayers
- decorative fountains.
Warm, stagnant water provides the right conditions for growth, according to the Occupational Safety and Health Administration (OSHA). The organism can multiply at temperatures between 68 degrees and 122 degrees Fahrenheit, and temps of 90 degrees to 105 degrees are optimal for that to occur.
A 2015 study by the Centers for Disease Control and Prevention (CDC) stated that “75 percent of (Legionnaires’ disease) acquired in health-care settings could be prevented with better water management.”
Ochsner Medical Center outbreak: remediation
A statement from hospital officials emphasized: “These cases have not been confirmed to have been acquired at OMC–Jefferson Highway.”
Still, those officials also said that precautionary steps are being enacted to ensure a safe environment for OMC’s patients, visitors, and staff:
- Extensive water testing is in progress across all of OMC–Jefferson Highway and will be ongoing for at least one year. OMC tests routinely as part of its water-management plan.
- OMC is implementing a response plan to remove any bacterial strains that could be in the water system.
- The rooms where the patients received care were taken out of service.
- OMC is augmenting its mechanical water delivery systems where appropriate.
- OMC’s Infection Prevention department will assess all patients at risk of pneumonia for Legionella and recommend additional testing when appropriate to the attending physicians.
- OMC is partnering closely with the Office of Public Health for its expertise and resources.
