Patient flow from critical care to renal services: a year-long survey in a critical care network.
BACKGROUND
The NSF for Renal Services stresses the importance of collaboration between renal services and critical care networks in managing patients with acute renal failure in the most clinically appropriate setting. Anecdotal evidence in our region suggested that some patients were remaining on critical care inappropriately because of a lack of capacity for step-down care in local renal units.


OBJECTIVE
To determine the number of extra days patients spend on critical care receiving single-organ renal support before transfer to a renal unit.


METHODS
Prospective, multi-centre, service evaluation.


METHODS
Prospective data were collected over a one-year period by either daily telephone calls or bedside review. Follow-up data were retrieved from electronic and patient records.


RESULTS
Five hundred and forty-two patients received renal replacement therapy (RRT) in critical care. With 68 (12.5%) patients already receiving RRT for end-stage renal failure, this gave an incidence of new RRT on critical care of 234 per million population per year. The median duration of RRT on critical care was 4 days (range 1-30). One hundred and twenty-seven patients (23%) were discharged from critical care still requiring RRT. A period of single-organ renal support (median 2 days, range 1-8) was provided to 74 of these patients (58%) using 113 critical care bed days.


CONCLUSIONS
Over half of patients receiving RRT on discharge from critical care in our network received a short period of single-organ renal support before step-down. This may represent either delayed discharge from critical care or a potential opportunity for care in an alternative high-dependency facility.
