Decreased technique-related morbidity for continuous ambulatory peritoneal dialysis

Area of Science:

• Nephrology
• Dialysis Technology
• Patient Outcomes

Background:

• Continuous ambulatory peritoneal dialysis (CAPD) and home hemodialysis (HHD) are crucial renal replacement therapies.
• Access-related complications historically contributed to significant patient hospitalization.
• Understanding trends in hospitalization is vital for optimizing dialysis care.

Purpose of the Study:

• To compare hospitalization rates for access-related causes between CAPD and HHD patients over time.
• To evaluate the impact of decreasing peritonitis incidence on hospitalization patterns.
• To identify reasons for hospitalization in CAPD patients beyond peritonitis.

Main Methods:

• Retrospective analysis of patient data from the Mayo Clinic.
• Comparison of hospitalization days per patient year (PPY) for access-related causes.
• Data stratified by initial treatment period (1979-1982 vs. 1985-1988).

Main Results:

• In 1979-1982, CAPD patients had 7.8 days PPY hospitalization for access causes vs. 1.6 days PPY for HHD.
• In 1985-1988, hospitalization decreased to 1.8 days PPY for CAPD and 1.2 days PPY for HHD.
• For CAPD patients in 1985-1988, over half of hospitalization time was for non-peritonitis reasons.

Conclusions:

• Dialysis access complication hospitalization rates have markedly improved for both CAPD and HHD.
• The gap in hospitalization between CAPD and HHD has narrowed significantly.
• Non-peritonitis related issues constitute a substantial portion of CAPD hospitalizations, warranting further investigation.
