Frailty JSNA

Introduction

Frailty is a complex clinical state in which age‑related declines across multiple body systems reduce an individual’s resilience to everyday or acute stressors. This means that relatively minor events—such as a mild infection or a small fall—can lead to disproportionate deterioration in health. Frailty is therefore used in the NHS as a key way of identifying older people at highest risk of poor outcomes including disability, falls, hospitalisation, and the need for long‑term care. It is increasingly recognised not only among older adults but also in groups facing multiple disadvantages, such as people experiencing homelessness, where high prevalence and earlier onset highlight the wide‑ranging nature of vulnerability associated with frailty1, 2.

Frailty prevalence is rising and it places significant pressure on local health and care systems. NHS England reports that frailty‑related demand is a major factor behind growing use of acute and community services, reflecting increasing complexity in population health needs. By March 2025, GPs had diagnosed approximately 1.51 million people in England with moderate or severe frailty, and demographic change means this number will continue to grow—ONS forecasts indicate a 73% increase in the population aged 85+ between 2025 and 20451, 3.

The wider societal and economic costs are substantial. Frailty was estimated to cost the UK healthcare system around £5.8 billion per year as of 2019, driven by higher rates of hospital admission, increased care needs, and greater dependency on long‑term support. For local authorities, early identification and coordinated support for people living with frailty are essential to improving quality of life, maintaining independence, reducing avoidable admissions, and managing demand on already stretched health and social care services1.
