Acute renal failure: the tip of the iceberg?
This study reports the experience, during a six-year period, of the Aberdeen Renal Unit in the treatment of patients with acute renal failure. The combination of a relatively stable population base and a single regional dialysis centre has allowed the incidence of acute renal failure to be assessed. Approximately 30 patients per million population were dialysed annually for acute renal failure; 69 per cent of these patients (20.5 per million population per year) were dialysed for acute reversible intrinsic renal failure (ARIRF) and mortality in this group was 44 per cent. Patients with more severe disease at the time of presentation to the renal unit, as defined by a clinical severity score, had significantly reduced survival rates. However, it was not possible to predict the outcome in individual cases; ten of 24 patients with clinical severity scores which indicated a poor prognosis survived the period of oliguria and were discharged from hospital. The fact that other renal units dialyse fewer patients per million population per year for ARIRF probably reflects a reluctance to refer patients whose general condition appears poor. As the overall mortality rate reported in this study does not differ significantly from rates reported previously from centres treating a smaller proportion of patients, such decisions may not be correct. It is well known that facilities in Britain for treating patients with end-stage renal disease are inadequate; it now appears likely that some patients who might benefit from acute dialysis are being denied treatment for a potentially reversible disease process.
