If ice machines in a hospital test positive for Legionella multiple times, what should the WMP team do?

• A. Remove all ice machines from service.
• B. Investigate and remediate the positive machines.
• C. Stop testing and monitor for complaints.
• D. Replace all the machines with new models.

Answer: (B)

Investigating and remediating the positive machines is the most appropriate response when ice machines test positive for Legionella multiple times. This approach is critical in ensuring patient safety while also addressing the underlying issues that led to the positive test results. The investigation involves assessing the water supply and system design, identifying possible sources of contamination, and evaluating maintenance practices. Remediation efforts can include disinfection protocols and repairs to any components that may contribute to creating favorable conditions for Legionella growth. This proactive strategy allows for the continuation of ice machine services while mitigating the health risks associated with Legionella. Ceasing operations of the ice machines entirely or replacing them with new models might seem like a straightforward solution, but these actions do not address the root causes of contamination. Stopping testing and simply monitoring for complaints can lead to a delayed response to a potential health crisis, as Legionella can pose significant risks, especially in vulnerable patient populations. By focusing on investigation and remediation, the WMP team can implement effective control measures that reduce the risk of future occurrences and protect the health of hospital patients.
