Abstract

Purpose

Assessment of the cost utility (CU) of acute renal replacement therapy (RRT) from a societal perspective during a 5-year follow-up.

Methods

This was a cross-sectional cohort study in a medical-surgical intensive care unit and an acute RRT unit of 410 consecutive patients treated with acute RRT in Helsinki University Hospital in 2000–2002. Five-year survival and health-related quality of life (HRQoL) were assessed and used to calculate quality-adjusted life years (QALYs) in two ways. They were first calculated for the 5-year follow-up period and, second, estimated for the expected lifetime. HRQoL was assessed by the EuroQol (EQ-5D) in 2003. The cost analysis included hospital costs during index hospitalization along with hospital and societal costs for the following 5 years. The CU ratio was determined as total costs divided by gained QALYs.

Results

Median survival time for all patients was 0.20 years and the EQ-5D index score was 0.68, 0.18 lower than that of the age- and gender-matched general population. All RRT-treated patients gained 0.10 QALYs/patient and hospital survivors 2.54 QALYs in 5 years. Overall the CU ratio was poor [5 year median 271,116 (29,782–2,177,581) €/QALY]. However, it was acceptable (less than 50,000 €/QALY) in patients who survived for more than a year and did not need chronic RRT. Cost utility decreased with increasing age exceeding 1.0 million €/QALY in the older groups.

Conclusions

In general, the CU ratio of acute RRT is poor. However, it is acceptable in patients with renal recovery who survive for more than 1 year.
