Objective: The aim of the present study was to investigate both the outcomes and prognostic factors of ARF patients requiring RRT in our Intensive Care Unit.
Design: It was a retrospective observational study. Setting: Pamela Youde Nethersole Eastern Hospital, a 20-bed medico-surgical ICU.
Patients and participants: ARF patients who had received RRT from January 2005 to December 2006 were recruited.
Interventions: The primary outcome was hospital mortality. Secondary outcomes were: dialysis dependency at hospital discharge, ICU and hospital length of stay. Relationship between demographics, premorbidities and clinical parameters with primary outcome was studied.
Measurements and results: One hundred and thirty-five patients were included in the final analysis. Hospital
mortality rate was 63.7%. The median survival was 24 days (IQR 7 to 746 days). Mechanical ventilation (HR
2.96, 95% CI 2.04 to 3.89) and hepatorenal syndrome (HR 2.29, 95% CI 1.63 to 2.95) were independently
associated with hospital mortality. Dialysis dependency rate after hospital discharge as on day 60 was 4.1%.
Conclusion: ARF in ICU was associated with a high mortality rate which was correlated with hepatorenal
syndrome and mechanical ventilation. Most of the hospital survivors were free from dialysis.
