In a new report by the Blue Cross Blue Shield Foundation, social, behavioral, and environmental factors are shown to determine a staggering 60% of one's overall health. The report provides overwhelming support for increased investment in, and collaboration with, social services as a way of improving overall individual and community health. The report's key findings include: -Providing housing support for low-income, high-need individuals can result in net savings due to reduced health care costs. The net savings range from $9,000 per person per year to nearly $30,000 per person per year for the Housing First model, a harm-reduction approach in which adults who are homeless and who have behavioral health conditions are provided supportive housing. -Nutritional assistance for high-risk women, infants, and children as well as older adults and people with disabilities lowers infant mortality rates, improves birth weights, reduces nursing home admissions, and significantly lowers federal and state Medicaid costs. -Vulnerable populations experience health gains when their care is coordinated across primary, specialty, behavioral, and social services and that hospitalizations and emergency department visits are demonstrably reduced. -Partnerships between health care and social service providers, particularly housing service providers, have been effective in improving health outcomes in certain high-need populations. -Income support programs, specifically the Earned Income Tax Credit (EITC) and Supplemental Security Income (SSI), were associated with better health outcomes for those individuals who qualify for such programs. By attributing 60% of one's health to social, behavioral, and environmental factors, Blue Cross Blue Shield is making known that social workers and social service programs are the key to improving the health of individuals and communities. The report opens the door for unprecedented collaboration between social workers and private sector health insurers, who can work together to address patient care as a whole unit. The report adds to the increasing evidence that integrated healthcare is the future of care delivery. Integrated care involves primary care providers and behavioral/mental health providers working in unison to treat the whole patient. Social workers, who are trained in interdisciplinary collaboration, are uniquely qualified to serve in this capacity. Most importantly, the message of the report is clear: achieving optimal health is impossible without increased investment in social service programs, especially for vulnerable populations. This provides a major opportunity to advocate on behalf of increased investment in programs that improve health while reducing healthcare costs. When one of the nation's largest health insurers says that social service programs are critical to the health of our nation, policy makers will have to listen.
