|---|
Background. Survival statistics for daily haemodialysis are lacking as most centres providing this have treated only a small number of patients for short observation times. We pooled our 23-year, 1006-patient-year, five-centre experience of 415 patients treated by short daily haemodialysis.
Methods. One hundred and fifty patients were treated in-centre, most because of medical complications and 265 by home or self-care haemodialysis. Patients were on daily haemodialysis for 29 ± 31 (0–272) months. Forty-two percent had primary and 31% had secondary renal failure. Treatment time was 136 ± 35 min, frequency 5.8 ± 0.5 times/week and weekly stdKt/V 2.7 ± 0.55.
Results. Eighty-five patients (20%) died; 5-year cumulative survival was 68 ± 4.1% and 10-year survival was 42 ± 9%. Age, secondary renal failure and in-centre dialysis were associated with mortality, while gender, frequency of dialysis (5, 6 or 7 per week), continent, country and blood access were not. Survival was compared with matched patients from the USRDS 2005 Data Report using the standardized mortality ratio and cumulative survival curves. Both comparisons showed that the survival of the daily haemodialysis patients was 2–3 times higher and the predicted 50% survival time 2.3–10.9 years longer than that of the matched US haemodialysis patients. Survival of patients dialyzing daily at home was similar to that of age-matched recipients of deceased donor renal transplants.
Conclusions. Survival of patients on short daily haemodialysis was 2–3 times better than that of matched three times weekly haemodialysis patients reported by the USRDS.
