The Gist of Geriatrics
Geriatrics is fundamentally about managing geriatric syndromes and multicomplexity through comprehensive assessment rather than treating individual diseases in isolation, with the ultimate goal of preserving functional status, independence, and quality of life in older adults. 1
Core Philosophy
Geriatrics represents a paradigm shift from disease-focused care to a holistic approach that recognizes older adults experience geriatric syndromes—clinical conditions like frailty, delirium, and falls that don't fit discrete disease categories but result from cumulative impairments across multiple body systems 1. The traditional health care emphasis on managing each disease separately delays identification of these syndromes, which directly impact functional status, quality of life, and mortality 1.
The Geriatric 5Ms Framework
The modern approach to geriatric care is structured around five key domains 1:
1. Mind
- Assess cognitive and psychological health first, as this influences all other domains
- Screen for dementia, delirium, and depression
- Recognize that cognitive impairment affects a patient's ability to participate in advance care planning and medication management
2. Mobility
- Evaluate fall risk and functional status
- Address mobility limitations that threaten independence
3. Medications
- Review and reconcile all medications, particularly high-risk ones
- Combat polypharmacy, which is associated with drug interactions, cognitive impairment, functional decline, and death 1
- Consider deprescribing when medication harm outweighs benefit
- Use tools like the Beers Criteria to identify potentially inappropriate medications 1
4. What Matters Most
- Identify patient's values, goals, and care preferences
- Ensure medical decisions align with meaningful health outcomes for the individual
- Engage in advance care planning 1
5. Multicomplexity
- Address how multiple chronic conditions and social determinants of health intersect
- Recognize the whole person living with complex biopsychosocial needs 1
Evidence of Effectiveness
Comprehensive geriatric assessment reduces disability, hospitalization, and institutionalization while improving quality of life 1. This interprofessional diagnostic process identifies medical, psychosocial, cognitive, physical, and functional needs, guiding coordinated care plans that manage health complexities and optimize overall well-being.
Critical Distinction
A geriatrician is not simply a physician who cares for old people 2. The specialty requires expertise in internal medicine combined with neurology, psychiatry, and rehabilitation medicine, focused on functional ability, preventive strategies, and person-centered care 2. The role involves reorienting care systems toward integrated approaches rather than fragmented disease management.
Common Pitfall
The prescribing cascade occurs when adverse drug effects are mistaken for new medical conditions, leading to additional unnecessary medications or diagnostic tests 1. Always consider whether a new symptom might be an adverse drug event before adding another medication.
