Mid-term cost-effectiveness of the liver transplantation programme of England and Wales for three disease groups

Liver transplantation has never been the subject of a randomized controlled trial, and there remains uncertainty about the magnitude of benefit and cost-effectiveness for specific patient groups. This article reports the results of an economic evaluation of adult liver transplantation in England and Wales. Patients placed on the waiting list for a liver transplant were observed over 27 months. The costs and health benefits of a comparison group, representing experience in the absence of liver transplantation, were estimated using a combination of observed data from patients waiting for a transplant and published prognostic models. The analysis focuses on three disease groups, for each of which prognostic models were available: primary biliary cirrhosis (PBC), alcoholic liver disease (ALD), and primary sclerosing cholangitis (PSC). A higher proportion of patients with ALD were assessed for a transplant but not placed on the waiting list. The estimated gain in quality-adjusted life-years from transplantation was positive for each of the disease groups. The mean incremental cost per quality-adjusted life-year (95% bootstrap confidence intervals) from time of listing to 27 months for patients with PBC, ALD, and PSC are pound29,000 (pound1,000 to pound59,000), pound48,000 (pound12,000 to pound83,000) and pound21,000 (-pound23,000 to pound60,000), respectively. In conclusion, liver transplantation increases the survival and health-related quality of life of patients with each of three end-stage liver diseases. However, the extent of this increase differs between different disease groups. Cost-effectiveness estimates were poorer for patients with ALD over the 27-month period than for patients with PBC or PSC. This in part reflects the costs of the higher number of ALD patients assessed for each transplant.
