According to the US Census Bureau, the US population aged 65+ years is expected to nearly double over the next 30 years, from 43.1 million in 2012 to an estimated 83.7 million in 2050. These demographic advances, however extraordinary, have left our health systems behind as they struggle to reliably provide evidence-based practice to every older adult at every care interaction. Age-Friendly Health Systems is an initiative of The John A. Hartford Foundation and the Institute for Healthcare Improvement (IHI), in partnership with the American Hospital Association (AHA) and the Catholic Health Association of the United States (CHA), designed Age-Friendly Health Systems to meet this challenge head on. Age-Friendly Health Systems aim to: Follow an essential set of evidence-based practices; Cause no harm; and Align with What Matters to the older adult and their family caregivers.
