Properly interpreting Legionella water sampling data is essential for facility management professionals to make informed decisions when managing risks and identifying targeted, effective mitigation measures. It is important to know when water sampling data indicates: 1) an expected and acceptable level of Legionella, 2) that additional surveillance is warranted but not cause for alarm, or 3) that a problem is present and further investigation and mitigation measures are necessary. Knowledge gaps in this area commonly result in an overreaction to the detection of Legionella, or, in the event of a real problem, not taking the right steps to target the source and implement an effective resolution. To arm facility management professionals with the knowledge needed to avoid these and other common mistakes, this session will cover:
1. Interpreting sampling data. 2. Actions to take in the event of a Legionella colonization. 3. Pros and cons of treatment systems. 4, Communicating with regulatory agencies.
Properly interpret Legionella water sampling results to determine if a risk is present, what level of response is needed and what actions to take.
Employ water sampling not only as a surveillance tool but also as a forensic tool to identify the source location of Legionella so that targeted corrective measures can be taken.
Evaluate the advantages and disadvantages of treatment systems to ensure that the system selected is compatible with the hospital’s water systems.
Effectively communicate with regulatory and accrediting agencies in the event of a case of Legionnaires’ disease.
