Abstract

QALY calcuations are currently being considered in the UK as a way of showing how the National Health Service (NHS) can do the most good with its resources. After providing a brief summary of how QALY calculations work and the most common arguments for and against using them to set NHS priorities, I suggest that they are an inadequate measure of the good done by the NHS because they refer only to its effects on what will be defined as the ‘patient community’. The benefit of the NHS to the wider community is best regarded as a public good—everyone benefits from the general belief that the NHS is there to provide care for those who fall into a state of medical need. QALY ideology threatens this belief because it gives efficiency a higher priority than caring in response to need. It is a fallacy that a QALY maximising health service will be a greater good to society, because this sort of quest for efficiency threatens the caring basis of the Welfare State as such.
