In England the National Institute of Health and Clinical Excellence (NICE) provides guidance on the provision of care that, in turn, is adopted by regional decision makers. The basis of this guidance is economic modelling of the relative health gains and costs associated with interventions. The recent extension of NICE’s remit to incorporate a public health function has raised questions about whether the current decision making template, with its exclusive concern with health based outcomes, is always appropriate. For example, an intervention to reduce obesity in children through physical activity may lead to greater social acceptance by peers and enjoyment, as well as the well documented improvements in the cardiovascular health of the child. Research continuing at the University of Birmingham is exploring the implications of a move away from the purely health based measure, towards a measure which looks at what people are able to do with their lives.
