A randomized multicenter trial to evaluate the effects of UV-Flash system on peritonitis rates in CAPD.

A number of systems and devices have been developed to reduce peritonitis in CAPD patients. One of the newer developed systems in the UV-Flash. A retrospective study was conducted in five Japanese hospitals to measure the efficiency of the UV-Flash system in reducing the peritonitis rate for CAPD patients. This study took place between January 1983 to January 1992. The UV-Flash system had a significantly lower peritonitis rate (1/46.6 patient months) compared to the Standard system (1/27.5), but showed nominal significance when compared to the Disconnect system (1/47.6). Due to the lack of differentiation in peritonitis rates between the UV-Flash and Disconnect system, patient types for both systems were analyzed. The study found more impaired patients on UV-Flash (37.2%) as opposed to the Disconnect (9.8%). These impaired patients treated on the UV-Flash system showed a significantly lower peritonitis rate (1/27.5) when compared to the Disconnect (1/9.7) system. The UV-Flash system proved able to achieve sufficient prevention of peritonitis in CAPD patients. Thus, this system can be successfully applied to high risk CAPD patients.
