Study evaluates cost-utility of MARS treatment in ALF patients

Numerous studies have documented the favorable effects of MARS albumin dialysis treatment on clinical and laboratory parameters and survival in liver failure patients. However, to ensure that limited resources are utilized in an ethical manner, the subjective feelings of the patient in terms of health-related quality of life and costs should also be taken into account. So far, only a few small non-randomized studies have focused on the cost-utility and the health-related quality of life of MARS-treated acute-on-chronic liver failure patients. Currently, there are no studies on the health-related quality or cost-utility of MARS treatment in acute liver failure (ALF).

The Helsinki MARS-study group, led by liver and transplant surgeon Helena Isoniemi, investigated the cost-utility and health-related quality of life in 90 MARS-treated ALF patients. Comparisons were made with a similar historical control group treated in the same intensive care unit. The 3-year outcomes and number of liver transplantations were recorded and all direct liver disease-related health care costs accrued during 3.5 years were determined. The health-related quality of life (HRQoL) before and after MARS was measured by using the 15D instrument. The HRQoL, cost, and survival data were combined and the incremental cost/quality-adjusted life year (QALY) ratio was calculated. This study is the first report evaluating the cost-utility of MARS treatment in ALF patients which will be published on May 14, 2010 in the World Journal of Gastroenterology.

This work was performed in the Surgical Hospital of Helsinki at the Helsinki University Central Hospital in collaboration with the Department of Anesthesiology and Intensive Care Medicine, Transplantation and Liver Surgery Clinic, Finnish Office for Health Technology Assessment at the National Institute for Health and Welfare, Group Administration of the Helsinki and Uusimaa Hospital Group, and Department of Public Health at the University of Helsinki.
