Comparison of the efficacy cost and complication rate of APD and CAPD as long-term outpatient treatments for renal failure.

We compared 10 patients treated with overnight APD in their homes with a parallel group of 30 patients having CAPD (Freeline II) over two years 1990 and 1991. Our aim was to discover if APD was an efficient and cost effective alternative to CAPD. The average amount of dialysate used per day in APD patients was 11 litres (range 9 to 14 litres) compared to 6.8 litres (range 6 to 10 litres) for CAPD. The average plasma creatinine was 920 umol/L, plasma urea of 21 mmol/L on APD and 825 umol/L and 24 mmol/L respectively on CAPD. In 1990 there were 2 incidences of peritonitis (2 in 1991) in the APD patients compared to 24 incidences (24 in 1991) in the CAPD patients with 6 recurrences (5 in 1991) and 19 exist site infections (24 in 1991). The average fluid costs plus disposables were comparable. However the cost of treating complications per patient for APD was for 1990 32 pounds (108 pounds in 1991) and for CAPD 832 pounds (1308 pounds in 1991). All the APD patients who had previously experienced CAPD preferred this treatment for its convenience and social acceptability. APD is a cost-effective alternative to CAPD and has advantages in some patients.
