A novel programme of supportive two-exchange assisted continuous ambulatory peritoneal dialysis for frail patients...

We have developed a supportive two-exchange assisted continuous ambulatory peritoneal dialysis (asCAPD) programme for the older frail person who cannot do autonomous PD and do not want or are considered to be too high risk for haemodialysis (HD). Evaluation of the programme was determined by data collected retrospectively from patient records. Primary outcome was comparison of symptoms at start of dialysis and 3 months following dialysis start. Secondary outcomes were survival and peritonitis rate. Over a 4-year period (2016-2020), 49 patients with mean age 79.6 years (range 47-90) enrolled in the programme with eGFR 7.7 ± 2.6 ml/min (mean ± SD) at dialysis start. Forty-one patients had been on asCAPD for >3 months. There was an improvement in all symptoms at 3 months compared to baseline: anorexia (46% to 15%), fatigue (46% to 15%), shortness of breath (27% to 2%) and oedema (51% to 32%). One-year survival was 55%. Peritonitis rate was 0.52 episodes per patient year. The novel supportive two-exchange asCAPD programme shows potential improvement of symptoms after 3 months and may provide an acceptable dialysis modality for the frail co-morbid person with established kidney failure. More detailed study and evaluation are needed.
