Lifelong health leadership: reframing geriatrics as a model of care for resilient health systems

Abstract Population ageing is commonly framed as a demographic challenge, biological frontier, or economic pressure. Yet these perspectives remain incomplete unless longevity is also understood as a leadership challenge. Gains in lifespan have not been matched by equivalent gains in healthspan, widening the period lived with multimorbidity, frailty, disability, cognitive vulnerability, loneliness, and dependency. Recent global analyses estimate a mean healthspan–lifespan gap of 9.6 years across 183 World Health Organization member states, while the population aged 60 years and older is projected to reach 1.4 billion by 2030 and 2.1 billion by 2050. This perspective aims to redefine the contribution of geriatrics across the life course and to propose a framework in which geriatricians act as lifelong health advocates within resilient, collaborative, and function-oriented health systems. This view argues that the longevity era requires geriatric care to evolve beyond the reactive management of late-life complexity toward anticipatory leadership of biological, functional, social, and organizational trajectories. Such transformation cannot be entrusted to geriatricians alone. It requires shared leadership across professions, organizations, communities, and policy systems. Geriatricians can contribute as physicians of trajectories, working with nurses, allied health professionals, managers, policymakers, patients, and communities to develop adaptive systems that preserve intrinsic capacity, functional ability, autonomy, and resilience before dependency becomes established. Drawing on healthy ageing, intrinsic capacity, integrated care, and health-system resilience, we propose “Lifelong Health Leadership” as a framework aligning clinical practice, organizational governance, workforce sustainability, intergenerational collaboration, and public health strategy. Rather than replacing traditional geriatrics, this framework expands its mandate and positions the discipline as a central contributor to health systems that anticipate vulnerability, preserve function, and support healthy longevity across the life course.
