Abstract
The short-term medical benefit of the liver dialysis system MARS in patients with severe acute liver disease has clearly been demonstrated. An economic analysis of MARS has not been presented previously. Objective of the study is to calculate the costs per life saved and life year gained and to measure health related quality of life in patients who survived acute liver failure. First results on survival and HRQL are presented here. Cost effectiveness and cost utility analysis of MARS are performed. All patients since 1993 with chronic liver failure (Bilirubin > 300 micro mol/l) of the university hospital Rostock are included in the original sample (n = 141). Survival data are calculated. Surviving patients were contacted personally, thus quality of life data (EQ 5D and SF12) determined. Patients were compared in case control study design. In a later stage inpatient hospital costs, direct and indirect outpatients costs are included in the analysis. MARS-Patients show a higher survival: Kaplan-Meier cumulative survival after 100 days: 0.59 after MARS, 0.39 without (P <0.05). There was no significant difference in health related quality of life (SF12 and EQ-D). Calculations of quality adjusted life years (QALYs) result in 0.116 QALYs gained by treatment of one patient with MARS in one year. First preliminary results suggest that 1 year after therapy MARS seems to have a positive effect concerning survival rate, survival time and QALYs gained. Final results of cost-effectiveness and cost-utility analysis will soon be presented.
