Health is affected by many factors beyond the medical care provided within the four walls of a hospital or clinic. While access to high-quality medical care is critical, research shows up to 80 percent of a person’s health is determined by social and environmental factors and the behaviors that emerge as a result. A substantial body of research has established that having an unmet resource need — including experiencing food insecurity, housing instability, unmet transportation needs and interpersonal violence or toxic stress — can significantly and negatively impact health and well-being. It can also increase healthcare utilization and costs.
