摘要

Purpose of Review

Much of what we learned over the last 40 years about preventing healthcare-acquired Legionnaires’ disease has been reimagined into new guidance and regulation. However, confusion persists about key elements of infection prevention. This review highlights these elements as they relate to effective water management.

Recent Findings

Reports of Legionnaires’ disease are on the rise. COVID shutdowns, regular outbreaks, and the costs associated with this disease have focused renewed attention on prevention. New requirements, both voluntary and mandatory, have been promulgated since 2015 that, if adopted, will have the effect of minimizing the risk for healthcare-associated Legionnaires’ disease. These include standards and guidelines from ASHRAE, the Center for Medicare & Medicaid Services (CMS), The Joint Commission, and the Centers for Disease Control and Prevention (CDC).

Summary

Prevention of healthcare-acquired Legionnaires’ disease is now based upon the principles of water management. This requires a multi-disciplinary approach that must include infection preventionists, facility engineers and administrative leadership. Testing for Legionella in healthcare water systems is no longer the controversy of old, but rather necessary to validate the effectiveness of water management.
