Purpose: This study evaluated improvements in dialyzer reuse parameters and clinical outcomes associated with a CQI project in a hospital‐based dialysis center in which high flux polysulfone dialyzers were replaced with high flux Polyflux® dialyzers (GAMBRO® Renal Products). Methods: Dialyzers were reprocessed using a Renatron® II Dialyzer Reprocessing System in conjunction with Renalin® sterilant (Minntech Corp.). Renalog® RM software was used to track dialyzer reprocessing rates and failures. Reasons for dialyzer failure included inadequate dialyzer volume; excess pressure; appearance; clotting during use; and maximum number of uses reached. The average number of dialyzer reuses with polysulfone dialyzers between January and June 2002 were compared to that achieved with Polyflux® dialyzers for the same periods in 2003 and 2004. Analysis periods were separated to avoid the impact of dialyzer transition on clinical parameters. Achievement of URR goals during these same periods was likewise compared. Results: Transition from polysulfone to Polyflux® dialyzers was associated with a >40% increase in average number of reuses between 2002 and 2003 and a >63% increase comparing the 2002 and 2004 periods. During the 2002 analysis period with polysulfone dialyzers the target URR of 65% was achieved in approximately 75% of hemodialysis patients; this increased to nearly 95% with Polyflux® dialyzers in both the 2003 and 2004 periods, despite more reprocessing of these dialyzers. Conclusions: These results demonstrate an improvement in both reuse efficiency and clinical outcomes associated with Polyflux dialyzers. Identifying clinical products through CQI studies that provide an economic and clinical advantage plays an important role in the success of hospital‐based hemodialysis.
