Geriatric syndromes

Last revised: 13 Jan 2020

  • The clinical presentation of illness in older people is often atypical, and a coherent, contextual and contemporaneous history may not be available.
  • Chronic complex comorbidities add additional challenges and can confound management.
  • Descriptive syndrome clusters (ie syndromes) are pragmatic tools that can facilitate mutual understanding between health professionals and patients.
  • The Geriatric 5M tool is a simple, practical tool that can be used as a framework by general practitioners in the assessment of the ageing patient.

The interaction between physiological changes associated with ageing and illness presentation provides general practitioners (GPs) with unique diagnostic challenges (refer to Part B. Physiology of ageing). In reality, the ‘one disease’ model of care sits uneasily for most patients, but especially for those who are older.

The clinical presentation of illness in older people is often atypical, which means a coherent, contextual and contemporaneous history may not be available. Often, a collateral description of the patient is the only information available to the GP.

An already atypical disease presentation in older patients is compounded by other comorbidities and individual patient context. Homeostasis also changes with age, which not only contributes to presentation and any future relevant investigation, but also affects pharmacokinetics and therapeutic options.

Any treatment and management of the above patient can therefore be complex and extends beyond the traditional medical model. Additionally, assessment cannot merely focus on the presenting issue; a full reflection of contextual medico-psycho-social assessment is required, including previously documented patient and family expectations.

Reflecting the challenges aforementioned, the term ‘geriatric giants’ was first coined in 1965 by British geriatrician Professor Bernard Isaacs. His syndrome cluster described four clinical issues:1

The four descriptive syndrome clusters above were proposed to enable clinicians to describe the actual ‘illness’ presentation – a descriptive pragmatic tool to facilitate a mutual understanding between health professionals and patients. Isaacs originally suggested that if appropriate assessments were in place, all common problems in older people would relate to one or other of these four descriptive terms.

By 2017, the nomenclature had evolved and four new geriatric syndromes were proposed:2

  • Frailty (refer to Part A. Frailty)
  • Sarcopenia
  • Anorexia of ageing
  • Cognitive impairment.

A notable absence from the new proposed list of geriatric syndromes was iatrogenic illness.

None of the proposed syndrome types reflect the traditional disease model of care; however, they have significant implications in terms of individual morbidity and mortality, and, indeed, healthcare costs.

GPs’ understanding of illness presentation in the older population will continue to evolve, and the nomenclature used will undoubtedly change.

In the current context, GPs are pragmatic and need logical tools to enable optimum patient management. The 5M tool provides a framework that reflects the evolving geriatric giant concept (refer to Table 1):3

  • Mind
  • Mobility
  • Medications
  • Multicomplexity
  • Matters most.
