Using a period life-expectancy framework, CSDE Affiliate Marcia Weaver (Health Metrics) tracked health-adjusted life expectancy (HALE) and lifetime spending in the United States for all ages, producing the first estimates calculated at birth, the most comprehensive measure. Weaver and co-authors used population-level results on mortality and years lived with disability from the 2019 Global Burden of Disease, Injuries, and Risk Factor Study and simulated effects of changes in healthcare for 132 causes. Increases in lifetime spending often occur at younger ages than increases in health-adjusted life expectancy (HALE), underscoring the importance of estimates calculated at birth.
