Abstract
RATIONALE & OBJECTIVE
Less than 4% of patients with kidney failure receive kidney transplants. Although discard rates of hepatitis C virus (HCV)-viremic kidneys are declining, ~39% of HCV-viremic kidneys donated between 2018 and 2019 were discarded. Highly effective antiviral agents are now available to treat chronic HCV infection. Thus, our objective was to examine the cost-effectiveness of transplanting kidneys from HCV-viremic donors into HCV-uninfected recipients.
STUDY DESIGN
Markov state transition decision model. Data sources include Medline search results, bibliographies from relevant English language articles, Scientific Registry of Transplant Recipients, and the US Renal Data System.
SETTING & POPULATION
US patients receiving maintenance hemodialysis who are on kidney transplant waiting lists.
INTERVENTION(S)
Transplantation with an HCV-unexposed kidney versus transplantation with an HCV-viremic kidney and HCV treatment.
OUTCOMES
Effectiveness measured in quality-adjusted life-years and costs measured in 2018 US dollars.
MODEL, PERSPECTIVE, AND TIMEFRAME
We used a health care system perspective with a lifelong time horizon.
RESULTS
In the base-case analysis, transplantation with an HCV-viremic kidney was more effective and less costly than transplantation with an HCV-unexposed kidney because of the longer waiting times for HCV-unexposed kidneys, the substantial excess mortality risk while receiving dialysis, and the high efficacy of direct-acting antiviral agents for HCV infection. Transplantation with an HCV-viremic kidney was also preferred in sensitivity analyses of multiple model parameters. The strategy remained cost-effective unless waiting list time for an HCV-viremic kidney exceeded 3.1 years compared with the base-case value of 1.56 year.
LIMITATIONS
Estimates of waiting times for patients willing to accept an HCV-viremic kidney were based on data for patients who received HCV-viremic kidney transplants.
CONCLUSIONS
Transplanting kidneys from HCV-viremic donors into HCV-uninfected recipients increased quality-adjusted life expectancy and reduced costs compared with a strategy of transplanting kidneys from HCV-unexposed donors.
