The reported prevalence of pain in these five countries represents a substantial burden to individuals, employers, healthcare systems and society in general. The fact that one in five of the adult population has experienced pain presents a major policy challenge. This would involve not only reducing the prevalence of pain - where chronic pain may be considered a disease in its own right - but to co-ordinate pain management programs across a range of disease states and socio-economic groups.
