The arrival of continuous renal replacement therapy (CRRT) has given t
he intensivist and the intensive care nurse the opportunity to treat a
cute renal failure (ARF) independently by giving them the necessary te
chnology and taking CRRT away from absolute nephrological control, Thi
s structural shift has created a controversy between those countries w
here control of CRRT has completely shifted to the intensivist and tho
se countries where nephrological input is still dominant, The argument
in favor of intensivist-driven CRRT rests upon several observations,
including the fact that therapy is continuous, as is the presence of t
he intensivist in the intensive care unit (ICU), Critically ill patien
ts require rapid changes in treatment that are best directed by physic
ians who are at the bedside all the time, CRRT must be seen within the
totality of patient care, and the intensivist can see the larger pict
ure more accurately, Intensivists are successfully performing more and
more procedures that were previously seen as part of other specialtie
s and, last but not least, ''closed'' models of ICU care appear to wor
k best, Australian intensivists have taken up CRRT from the start and
now control it, Patient outcomes under such a system, as reported here
, are above average, and confirm the effectiveness of such an approach
