Legionella risk assessments in healthcare: a critical step in patient safety
In healthcare environments, the stakes for managing building safety are higher than almost anywhere else and delays can costly. Hospitals, clinics, care homes, and medical centres serve some of the most vulnerable people in society – which makes Legionella risk management not just a regulatory requirement, but a matter of patient safety.
Legionnaires’ disease is a potentially fatal form of pneumonia caused by inhaling water droplets containing Legionella bacteria. For immunocompromised patients, the elderly, or those with respiratory conditions, the risk is significantly heightened. That’s why robust Legionella risk assessments are a cornerstone of healthcare facilities management.
Understanding the risk
Legionella bacteria thrive in warm, stagnant water – often within complex plumbing systems, storage tanks, showers, taps, and medical equipment that uses water. Given the size and nature of most healthcare facilities, these environments can present ideal conditions for bacterial growth if not properly maintained.
Healthcare buildings often contain:
- Large and intricate water systems
- Varying water usage across wards and departments
- Areas with low flow or infrequent use
- Specialised equipment that uses or stores water
Without proper monitoring, these systems can quickly become high-risk zones.
What a healthcare Legionella risk assessment involves
A comprehensive Legionella risk assessment for healthcare facilities includes:
- Reviewing all water systems, outlets, and associated plant
- Identifying high-risk areas and vulnerable user groups
- Testing and validating water temperatures
- Evaluating current maintenance and control regimes
- Producing a clear, site-specific risk management plan
In many cases, a water safety plan is required, guided by a multidisciplinary Water Safety Group (WSG), ensuring a coordinated approach across estates, infection control, and clinical teams.
