When flushing the entire domestic water system due to Legionella risk, how should bathroom faucets in occupied patient rooms be flushed?

Flushing bathroom faucets in occupied patient rooms at low flow to minimize the risk of transmission is the most appropriate approach. This method helps to reduce aerosolization of water droplets, which can occur when water is expelled at high velocity. Aerosolized water can carry Legionella bacteria, increasing the risk of inhalation by patients, especially those with compromised immune systems or existing respiratory conditions.

Using low flow reduces the likelihood of creating a fine mist that could potentially expose vulnerable individuals to the pathogens in the water. It is a key practice in infection control, particularly in healthcare settings where patients may be at high risk for serious complications from Legionella exposure.

Adjusting the flow to a lower rate is critical, especially when dealing with a population that may be particularly susceptible to infections. Therefore, the strategy of flushing at low flow is not only a preventative measure but also aligns with best practices for maintaining patient safety during a Legionella risk management operation.
