Background In 2003 two patients on the Haematology Ward at a teaching hospital in the north west of England developed Pseudomonas spp. infections in their central lines. As the water supply can be a source of nosocomial infections, point-of-use (POU) filtration was considered to reduce the likelihood of such occurrences. Aim Implement POU filtration for immunocompromised patients. Methods Previously, immunocompromised patients were required to drink only sterile bottled water. A disposable POU filter (Pall Medical, UK) was subsequently fitted to a dedicated drinking water tap on the haematology ward. In addition, disposable POU showerhead filters were implemented in two isolation rooms. Discussion Evidence suggests that hospital water supplies can be contaminated with microorganisms such as Pseudomonas spp., Legionella spp. and Aspergillus spp. Due to complex pipe work systems and biofilm formation, it can prove difficult for systemic treatments to completely eradicate microbial contamination. With this in mind, a recent publication suggests that a multi-barrier approach is necessary to reduce healthcare associated infections and this can include point-of-use filtration. Conclusion Pall-Aquasafe Water Filters are now routinely used on the haematology ward to provide safe water for drinking and showering for high-risk patients.
