The rise in health care spending and what to do about it.

Reforms for slowing the growth in health care spending and increasing the value of care have largely focused on insurance-based solutions. Consumer-driven health care represents the most recent example of this approach. However, much of the growth in health care spending over the past twenty years is linked to modifiable population risk factors such as obesity and stress. Rising disease prevalence and new medical treatments account for nearly two-thirds of the rise in spending. To be effective, reforms should focus on health promotion, public health interventions, and the cost-effective use of medical care.
