Aim:
To determine the short-term cost-utility of molecular adsorbent recirculating system (MARS) treatment in acute liver failure (ALF).
Methods:
A controlled retrospective study was conducted with 90 ALF patients treated with MARS from 2001 to 2005. Comparisons were made with a historical control group of 17 ALF patients treated from 2000 to 2001 in the same intensive care unit (ICU) specializing in liver diseases. The 3-year outcomes and number of liver transplantations were recorded. All direct liver disease-related medical expenses from 6 mo before to 3 years after ICU treatment were determined for 31 MARS patients and 16 control patients. The health-related quality of life (HRQoL) before MARS treatment was estimated by a panel of ICU doctors and after MARS using a mailed 15D (15-dimensional generic health-related quality of life instrument) questionnaire. The HRQoL, cost, and survival data were combined and the incremental cost/quality-adjusted life years (QALYs) was calculated.
Results:
In surviving ALF patients, the health-related quality of life after treatment was generally high and comparable to the age- and gender-matched general Finnish population. Compared to the controls, the average cost per QALY was considerably lower in the MARS group (64,732 euros vs 133,858 euros) within a timeframe of 3.5 years. The incremental cost of standard medical treatment alone compared to MARS was 10,928 euros, and the incremental number of QALYs gained by MARS was 0.66.
Conclusion:
MARS treatment combined with standard medical treatment for ALF in an ICU setting is more cost-effective than standard medical treatment alone.
Insights
Molecular adsorbent recirculating system (MARS) treatment for acute liver failure (ALF) is more cost-effective than standard care alone. MARS offers a lower average cost per quality-adjusted life year (QALY) while improving patient outcomes.
Area of Science:
- Hepatology
- Critical Care Medicine
- Health Economics
Background:
- Acute liver failure (ALF) presents significant treatment challenges.
- Molecular adsorbent recirculating system (MARS) is an extracorporeal liver support technology.
- Evaluating the cost-effectiveness of novel treatments is crucial for healthcare systems.
Purpose of the Study:
- To determine the short-term cost-utility of MARS treatment in ALF patients.
- To compare the cost per quality-adjusted life year (QALY) between MARS and standard medical treatment.
- To assess the impact of MARS on patient survival and health-related quality of life (HRQoL).
Main Methods:
- A retrospective controlled study involving 90 ALF patients treated with MARS and a historical control group.
- Collection of 3-year outcome data, including liver transplantations and survival rates.
- Determination of direct medical expenses and estimation of HRQoL using the 15D questionnaire.
Main Results:
- Surviving ALF patients receiving MARS treatment demonstrated high HRQoL, comparable to the general Finnish population.
- The average cost per QALY was significantly lower in the MARS group (64,732 euros) compared to controls (133,858 euros) over 3.5 years.
- MARS treatment resulted in an incremental gain of 0.66 QALYs with an incremental cost of 10,928 euros compared to standard treatment alone.
Conclusions:
- MARS treatment, when combined with standard medical care for ALF in an ICU setting, is more cost-effective.
- The findings support the integration of MARS as a valuable therapeutic option for ALF.
- MARS offers a favorable economic profile alongside clinical benefits in managing acute liver failure.
