RESUMEN
This study surveyed the availability and current practice of renal replacement therapy on adult general intensive care units in the United Kingdom. Questionnaires were returned from 236 units (89%). Renal replacement therapy was provided by 212 (90%) of responding units, treating 9442 patients per year. Renal physicians were involved in the initiation and prescription of treatment in 22 (11%) units. Ninety-one units (43%) had no step down facility on-site for those patients still requiring renal replacement therapy but no longer requiring intensive care. Continuous techniques are used by the majority of units, most commonly, continuous veno-venous haemofiltration, with an ultrafiltration rate of 2000 ml.h-1. Fifty-eight units (28%) use haemofiltration as adjuvant treatment in septic shock. The provision and practice of renal replacement therapy is now an integral part of intensive care medicine in the United Kingdom.
