There is a growing consensus that if healthcare is to be sustainable, there is a need for a fundamental shift from treatment of ill health, when it occurs, to prevention. This week we launched our report The transition to integrated care: population health management in England, with findings derived from extensive literature reviews and our experience working with health economies internationally. It highlights key challenges and potential solutions that, if adopted at scale, could deliver a more cost-effective approach to improving the health and wellbeing of a population.
