While much energy has been invested in improving the care experience and reducing costs, the final aim of improving population health remains elusive — a Ghost Aim.
So it comes as no surprise that the United States still ranks last among 11 industrialized countries on health system quality, efficiency, access to care, equity, and healthy lives. After all, only 10% of health outcomes are affected by medical care, whereas 60% are rooted in social and environmental factors and associated behaviors — which are the essence of population health.
