Sofosbuvir: a fork in the road for NICE?
NICE recently completed their appraisal of the hepatitis C drug sofosbuvir(Health 2015). However, as has been reported in the media, NHS England will not be complying with the guidance within the normal time period(Boseley 2015).
The cost of a 24 week course of sofosbuvir is almost £70,000. Around 160,000 people are chronically infected with the hepatitis C virus in England(Public Health England 2014), so that adds up to a fair chunk of the NHS budget. Yet the drug does appear to be cost-effective. ICERs differ for different patient groups, but for most scenarios the ICER is below £30,000 per QALY. In the NICE documentation, a number of reasons are listed for NHS England’s decision. But what they ultimately boil down to — it seems — is affordability.
The problem is that NICE doesn’t account for affordability in its guidance. One need only consider that the threshold has remained unchanged for over a decade to see that this is true. How to solve this problem really depends on what we believe the job of NICE should be. Should it be NICE’s job to consider what should and shouldn’t be purchased within the existing health budget? Or, rather, should it be NICE’s job simply to figure out what is ‘worth it’ to society, regardless of affordability? This isn’t the first time that an NHS organisation has appealed against a NICE decision in some way(Wells 2007). Surely, it won’t be the last. These instances represent a failure in the system, not least on grounds of accountability for reasonableness(Daniels 2000). Here I’d like to suggest that NICE has 3 options for dealing with this problem; one easy, one hard and one harder.
The simplest option involves the fewest changes to the NICE process. Indeed, it would involve doing pretty much what it does now, only with slightly different (and more transparent) reasoning. In this scenario NICE would explicitly ignore the problem of affordability. Its remit would cease to be the consideration of optimality on a national level and it would ignore the budget constraint. NICE’s remit would become figuring out which health technologies are ‘worth it’; i.e. would the public be willing to purchase a given technology with a given health benefit at a given cost. To some extent, therefore, NICE would become a threshold-setter. The threshold should be based on some definition of a social value of a QALY. This is the
