The impact of social determinants of health (SDOH) as drivers of medical utilization, cost, and health outcomes is both widely researched and acknowledged. This growing body of evidence attributes as much as 40 percent of health outcomes to SDOH such as housing, education, poverty, and nutrition and that as much as a third of the deaths in the United States can be accounted for by social factors. The influence of SDOH is particularly pronounced in vulnerable high-need, high-cost (HNHC) populations with single to multiple functional limitations.
