In France, frailty Syndrome is managed by geriatricss. Frailty syndrome is a clinical state of increased vulnerability to stressors in older adults caused by decline across multiple physiological systems. Pooled prevalence in community-dwelling adults aged 65 and over is roughly 11% for frailty and 42% for pre-frailty, rising to 38% in those over 90 and 75% in nursing home residents.
Frailty syndrome (ICD-10: R54) is a clinical state of increased vulnerability in older adults that arises from age-related decline in reserve and function across multiple physiological systems (musculoskeletal, immune, neuroendocrine, cardiovascular, metabolic). It is distinct from disability (the inability to perform activities of daily living) and comorbidity (the presence of multiple chronic diseases) but overlaps with both. Two complementary frameworks dominate: the Fried physical phenotype, which defines frailty as three or more of unintentional weight loss above 4.5 kg in a year, self-reported exhaustion, weakness on hand grip-strength testing, slow gait speed below 0.8 m/s, and low self-reported physical activity (one or two of these defines pre-frailty); and the Rockwood deficit-accumulation model, which counts deficits (symptoms, signs, diseases, disabilities) and expresses frailty as a continuous index from 0 to 1. The Clinical Frailty Scale (CFS) is a 9-point visual judgement scale developed by Rockwood and validated in multiple settings — 1-3 represents fit to managing well, 4 living with very mild frailty, 5-7 mild to severe frailty, 8 very severe, 9 terminally ill.
The key symptoms of Frailty Syndrome are: Unintentional weight loss greater than 4.5 kg (10 lbs) or 5% of body weight in the past year., Self-reported exhaustion: feeling everything is an effort or that you cannot get going for at least 3 days a week., Reduced hand grip strength below age- and sex-adjusted thresholds (lowest 20% on Jamar dynamometry)., Slow walking speed under 0.8 m/s over a 4-metre course at usual pace., Low physical activity, with weekly energy expenditure below the lowest 20% by sex., Increasing difficulty with instrumental activities of daily living such as shopping, cooking, handling finances, and using transport., Multiple falls or near-falls in the past year, often without obvious cause..
Assessment uses a combination of brief screening and comprehensive geriatric assessment. Screening tools take 1-5 minutes: the FRAIL questionnaire (5 items — Fatigue, Resistance to climbing stairs, Ambulation 1 block, Illnesses ≥5, Loss of weight ≥5%); the Clinical Frailty Scale (9-point visual judgement scale based on patient history and examination); and gait speed over 4 metres (≤0.8 m/s indicates frailty). Confirmed frailty triggers a comprehensive geriatric assessment by a geriatrician or geriatric specialist nurse covering physical health (chronic diseases, vision, hearing, dentition, continence), mental health (cognition with MMSE/MoCA, mood with PHQ-9 or GDS), functional status (Barthel index for ADL, Lawton scale for IADL), social circumstances (informal support, housing, finances), and a medication review with deprescribing where appropriate. Investigations target reversible contributors: full blood count, ferritin, vitamin B12, folate, vitamin D, thyroid function, renal function, glucose, HbA1c, calcium, and albumin; targeted imaging or specialist referral for new weight loss, anaemia, or falls. The Rockwood Frailty Index counts deficits from a 30- to 70-item list and produces a continuous score (frailty index ≥0.25 indicates frailty); it is increasingly used in research and electronic health records. Surgical and oncological pathways now use frailty assessment to risk-stratify and modify treatment intensity, including the use of the Edmonton Frail Scale, ACS-NSQIP Surgical Risk Calculator, and the G8 geriatric oncology screening tool.
Frailty assessment is part of routine primary care for older adults. Geriatric specialist referral is warranted when frailty is moderate to severe, when multiple reversible contributors are suspected, before major elective surgery, after multiple unplanned admissions, or when complex deprescribing is needed. Surgical and oncological specialists should integrate frailty assessment into treatment planning.
Find specialists →Strength and gait speed begin to improve within 6-8 weeks of starting structured exercise and nutrition. Maximum functional gains usually appear by 12-26 weeks. Transition from pre-frail to robust takes 3-6 months in most responders. After hospitalisation, regaining baseline function may take 6-12 months. Long-term maintenance requires continued exercise, nutrition, and medication review.
Choose a geriatrician or specialist clinical service with experience in comprehensive geriatric assessment, multidisciplinary working, and proactive care planning. Ask whether the service offers prehabilitation, structured deprescribing, and fall prevention programmes. Look for clinicians familiar with the Clinical Frailty Scale and Rockwood Frailty Index.

Frailty is a strong predictor of falls, disability, hospitalisation, postoperative complications, and death. Compared with robust older adults, frail individuals have 1.5-3 fold higher 5-year mortality after adjusting for age and comorbidity. However, frailty is not a one-way trajectory. In longitudinal studies, 23-40% of pre-frail individuals transition back to robust status over 3-5 years when active management is provided. Multicomponent exercise plus nutrition can reverse pre-frailty in 30-50% of older adults and reduce functional decline in those already frail. Comprehensive geriatric assessment improves outcomes after acute hospitalisation, reducing nursing-home admissions by 18% and mortality by 9%. Prehabilitation before major surgery cuts complications by 30-50%. Even in very severe frailty (CFS 8-9), proactive palliative care, advance care planning, and avoidance of harmful medications improve quality of life.
Multicomponent exercise is the cornerstone of frailty management: progressive resistance training 2-3 times weekly (8-10 major muscle groups, 8-12 repetitions per set, 2-3 sets), 150 minutes per week of moderate aerobic activity, balance training 2-3 times weekly (tai chi, Otago programme), and daily flexibility work. Supervised programmes are preferable for moderate-severe frailty; home-based programmes work for pre-frail and mildly frail individuals.
