Why do you need to flush Water Outlets in Healthcare Facilities?
In healthcare settings, ensuring the safety of the water supply is vital to protecting vulnerable patients from potentially deadly waterborne pathogens. One key water safety protocol often overlooked is the regular flushing of water outlets like taps and showers. Flushing outlets help remove stagnant water which allows hazardous bacteria to proliferate. Failing to flush outlets properly can enable the growth of organisms like Legionella, Pseudomonas and nontuberculous mycobacterium which can cause serious illnesses in hospital patients.
What happens when water is allowed to stagnate?
The dangers of stagnant water are that when water is allowed to sit in pipes and outlets, it creates an ideal environment for bacterial growth. Certain pathogens thrive in warm, stagnant water and can form biofilms that protect them and allow them to multiply rapidly. Legionella pneumophila, the bacteria which causes the potentially fatal Legionnaires Disease, are hazardous organisms commonly found in building water systems that fail to be properly flushed and disinfected. Pseudomonas aeruginosa is another waterborne pathogen of great concern in healthcare facilities, as it can cause serious infections in vulnerable patients.
How does flushing prevent pathogens from multiplying?
- Removal of stagnant water: Flushing removes stagnant water and replaces it with fresh water.
- Reduction of Biofilm: Biofilms are thin layers of microorganisms that can form in the inner surface of pipes. Regular flushing helps to dislodge and remove these biofilms, reducing the habitat for pathogens.
- Maintaining disinfection levels: Many water systems use chlorine or other disinfectants to kill pathogens. In stagnant water, these disinfectants can become depleted over time. Flushing brings in fresh water with higher disinfectant levels, helping to maintain the system’s ability to kill pathogens.
- Temperature control: Flushing can maintain lower water temperatures in the pipes, especially in hot climates. Many pathogens thrive in warmer water, so keeping the water cooler can inhibit their growth.
- Removal of sediments: Flushing helps remove sediments that can accumulate in pipes. These sediments can harbour bacteria and protect them from disinfectants.
- Oxygenation: Flushing introduces oxygen-rich water into the system, which can help prevent the growth of anaerobic bacteria that thrive in low-oxygen environments.
- Dilution of contaminants: If any contaminants have entered the system, flushing helps dilute them, reducing their concentration and potential harmful effects.
- Maintaining water quality: Regular flushing helps maintain overall water quality by removing potential contaminants and ensuring that fresh, treated water is circulating through the system.
Why is there a need for flushing protocols to be implemented and adhered to?
- Patient Safety: Healthcare facilities serve vulnerable populations who may be more susceptible to waterborne pathogens. Proper flushing helps protect patients from infections.
- Prevention of healthcare-associated infections (HAIs): Waterborne pathogens like legionella can cause serious HAIs. Understanding and implementing proper flushing protocols can significantly reduce this risk.
- Compliance with regulations: Healthcare facilities are required to follow specific water management plans, including flushing protocols, to meet health and safety regulations.
- Cost-effectiveness: Preventing waterborne infections through proper flushing can save healthcare facilities significant costs associated with treating HAIs and potential legal liabilities.
- Staff Safety: Healthcare workers are also at risk from waterborne pathogens. Proper flushing protects staff as well as patients.
- Crisis prevention: Understanding flushing protocols can help prevent water-related crises in healthcare facilities, such as outbreaks of waterborne diseases.
- Continuous improvement: Ongoing education allows healthcare facilities to stay updated on best practices and new technologies in water management.
Flushing protocols are critical to prevent the proliferation of these dangerous bacteria, healthcare facilities must implement strict flushing protocols for all water outlets, especially those in patient areas or other outlets that see infrequent use. This flushing helps remove stagnant water from pipes and outlets and makes it harder for pathogens to take hold. Outlets in patient rooms, public bathrooms, staff hand wash basins and other areas should be routinely flushed, even if not in use, to keep water flowing. Flushing is particularly important after any water disruptions or when outlets have gone unused for a period of time.
