France has implemented a nationwide healthy longevity program based on the World Health Organization's Integrated Care for Older People (ICOPE) model, creating a template for other countries seeking to improve aging outcomes at scale. The ICOPE approach prioritizes functional abilities and well-being over traditional disease-focused care, using person-centered interventions to maintain independence and quality of life in older adults. The French implementation focuses on early detection of declining intrinsic capacity across six domains: cognition, mobility, nutrition, vision, hearing, and psychological well-being. Healthcare providers screen for functional decline and intervene with targeted support before serious disability develops. The program integrates primary care, specialist services, and community resources to deliver coordinated care tailored to individual needs. Initial deployment data suggests the model can reduce emergency hospitalizations and nursing home admissions while improving patient-reported outcomes. The French experience demonstrates how national health systems can shift from reactive disease treatment to proactive functional preservation, offering a scalable framework for addressing population aging challenges globally.
