The Whole Health Index (WHI) is an industry-leading assessment tool developed by Elevance Health for defining and measuring the whole health of individuals and populations. It includes 93 inputs from three domains: Social Drivers, Global Health, and Clinical Quality. WHI methodology has been validated by Mathematica, published in the New England Journal of Medicine's Catalyst, and is patent pending.
Harnessing Data With the Whole Health Index
The WHI was developed by an expert panel of clinicians, subject matter experts, and population health researchers. It incorporates the National Academy of Medicine's Vital Signs framework, a set of evidence-based measures considered key to optimal health, and it has been assessed for validity and reliability by Mathematica, an independent research and data analytics consultancy.
The WHI at Work
The WHI has been calculated for over 40 million people served by our affiliated health plans across all lines of business. Using the results, we are deploying strategies, programs, and interventions aimed at supporting the people and communities who most need our help. For example, before the 2023 flu season, we identified 25 percent of members across our Commercial, Medicare, and Medicaid businesses with lower-than-average WHI scores. We then launched a campaign to help them learn about and get the vaccine.
Data from this effort shows that these members were up to 19 percent more likely to get the vaccine than other groups.
We will continue to lead the industry in improving how we measure whole health to best support people with personalized and equitable healthcare.
