Beyond the Standard Physical: The Purpose of a Comprehensive Geriatric Assessment
A comprehensive geriatric assessment (CGA) provides a holistic view of an older adult’s health, moving beyond chronological age to evaluate physiological and functional age. This multidisciplinary evaluation involves various healthcare professionals and aims to create a coordinated and personalized care plan. The primary goal is to maintain and improve functional ability, independence, and quality of life.
The Core Domains of a Comprehensive Geriatric Assessment
A CGA systematically evaluates multiple domains to build a complete picture of an individual's health.
Functional Status
This domain assesses the ability to perform daily activities.
- Activities of Daily Living (ADLs): Basic self-care tasks like bathing and dressing.
- Instrumental Activities of Daily Living (IADLs): More complex tasks for independent living, such as managing finances or shopping.
Cognitive and Psychological Health
Assessment of mental function is crucial, as cognitive impairment and mood disorders are common.
- Cognitive Function: Screening tools like MoCA or MMSE evaluate memory, language, and attention.
- Psychological Well-being: The Geriatric Depression Scale (GDS) screens for depressive symptoms.
Nutritional Status
Malnutrition is a risk factor for poor health outcomes.
- Screening: Simple questions can indicate problems.
- Assessment Tools: The Mini Nutritional Assessment (MNA) helps identify individuals at risk.
Social and Environmental Factors
Living situation and social network significantly impact health.
- Social Support: Reviews informal support from family and friends and community resources.
- Environmental Safety: Evaluates the home for hazards that could lead to falls.
Medication Review (Polypharmacy)
Many older adults take multiple medications, increasing the risk of adverse events.
- Identification of Issues: Reviews all medications to identify potentially inappropriate prescriptions.
- Deprescribing: May lead to reducing or stopping medications to improve outcomes.
A Comparison of Geriatric Assessment Approaches
| Feature | Rapid Geriatric Screening | Comprehensive Geriatric Assessment (CGA) |
|---|---|---|
| Purpose | Quickly identify individuals who need a full CGA. | Provide a detailed, holistic evaluation for creating a personalized care plan. |
| Time Commitment | Typically 5–15 minutes. | Up to 45 minutes or more, often over several sessions. |
| Who Administers | Non-specialists or nurses. | A multidisciplinary team of specialists. |
| Scope | Targets a few key domains, like frailty or cognitive impairment. | Covers all major domains systematically. |
| Best Use | Busy primary care settings. | For frail, complex, or high-risk patients who would benefit from a detailed plan. |
Actionable Interventions Based on Assessment Findings
The value of geriatric assessment lies in tailored interventions. Results from a CGA drive strategies to promote healthy aging.
- Personalized Exercise Programs: Recommend exercises focusing on balance, strength, and endurance to reduce fall risk.
- Targeted Nutritional Counseling: Provide dietary advice and potentially supplementation for individuals at risk of malnutrition.
- Medication Optimization: Address polypharmacy by adjusting or deprescribing medications.
- Cognitive Stimulation: Encourage mentally stimulating activities to maintain cognitive health.
- Social Engagement Support: Connect individuals with community programs to foster social connections.
- Environmental Modifications: Recommend home safety improvements to prevent falls.
- Care Coordination: Ensure all healthcare providers are informed for better coordinated care.

The Path Forward: Promoting Proactive Healthy Aging
The World Health Organization's vision of "healthy ageing" aligns with the principles of CGA, focusing on maintaining functional ability. A proactive, multidimensional approach to geriatric assessment empowers older adults. Integrating regular assessments and personalized interventions helps to delay functional decline, improve quality of life, and ensure aging is a period of vitality and independence. Assessment of the elderly aging process is the foundation for effective senior care.
