Issues in evaluating treatment for HCV
Trials of interferon and ribavarin (CMB): effective 43% cases
High cost intervention (approx £9000)
Without treatment
- 30% of cases progress to cirrhosis within 20 years
- Incidence of liver cancer (HCC) from cirrhosis of 1-4% per year
Question: Is treatment relatively cost-effective?
Need a model to estimate lifetime costs and effects
NICE says:
- YES for moderate and cirrhosis: cost per QALY approx £7,500
- UNKNOWN for mild cases
