Comprehensive Geriatric Assessment – What to Expect & Why It Matters
A comprehensive geriatric assessment (CGA) is a multidimensional, interdisciplinary evaluation of an older adult's health – covering medical, functional, cognitive, psychological, and social domains. Unlike a standard medical check-up, a CGA is designed to capture the full picture of a senior's health and well-being, enabling personalised care plans.
of seniors have at least one undiagnosed condition that affects their quality of life – but a CGA can help uncover these issues and create a comprehensive care plan.
What Is a Comprehensive Geriatric Assessment?
A comprehensive geriatric assessment (CGA) is a systematic process used by healthcare professionals to evaluate the overall health and functional ability of older adults. It goes far beyond a traditional physical exam by considering the whole person – not just their medical conditions, but also their ability to perform daily tasks, their mental health, their social support, and their environment.
The CGA is typically performed by an interdisciplinary team that may include a geriatrician, nurse, social worker, occupational therapist, physiotherapist, and clinical psychologist.
The 5 Domains of a Comprehensive Geriatric Assessment
1. Medical Assessment
Evaluation of all medical conditions, medications, and health status.
- Medical history: Current and past conditions, surgeries, hospitalisations.
- Medication review: All prescribed, over-the-counter, and herbal medicines – checking for interactions.
- Physical examination: Heart, lungs, abdomen, neurological exam, vision, hearing.
- Investigations: Blood tests, urine tests, ECG, X-rays as needed.
- Screening: For hypertension, diabetes, thyroid disorders, anaemia, and other common conditions.
2. Functional Assessment
Evaluation of the ability to perform daily activities independently.
- Activities of Daily Living (ADLs): Bathing, dressing, toileting, eating, walking, personal hygiene.
- Instrumental Activities of Daily Living (IADLs): Cooking, shopping, managing finances, using transport, housework.
- Gait and balance: Walking speed, balance tests, risk of falls.
- Strength: Muscle strength and endurance.
- Assistive devices: Use of walkers, canes, or other aids.
3. Cognitive Assessment
Evaluation of memory, attention, language, and executive function.
- Mental status screening: Mini-Mental State Examination (MMSE), Montreal Cognitive Assessment (MoCA).
- Memory: Short-term and long-term memory tests.
- Attention and concentration: Ability to focus and sustain attention.
- Executive function: Planning, organisation, problem-solving.
- Language: Fluency, comprehension, naming.
- Delirium screening: In acute settings.
4. Psychological Assessment
Evaluation of emotional and mental health.
- Depression screening: Geriatric Depression Scale (GDS), PHQ-9.
- Anxiety screening: GAD-7 or other anxiety scales.
- Mood: General mood, emotional well-being.
- Coping: How the person handles stress and challenges.
- Psychiatric history: Previous or current psychiatric conditions.

- Social support: Family, friends, community involvement.
- Loneliness and isolation: Frequency of contact and social engagement.
- Caregiver assessment: If they have a caregiver, assess their burden and well-being.
- Advance directives: Whether they have expressed preferences for future care.
- Financial and legal: Financial concerns, access to resources, legal matters.
The CGA Process – What to Expect
- Referral: A CGA is often initiated by a healthcare provider when they identify a need – for example, recent decline in function, frequent falls, or multiple unplanned hospital visits.
- Initial assessment: The geriatrician and team meet the patient and family to gather information about medical history, concerns, and goals.
- Comprehensive evaluation: Over one or more visits, the team conducts the full assessment across all five domains.
- Care planning: The team integrates all the information to create a personalised care plan – this may include medication adjustments, therapy referrals, home modifications, or social support referrals.
- Implementation: The plan is shared with the patient, family, and other healthcare providers.
- Follow-up: The team monitors progress and adjusts the plan as needed.
Why Comprehensive Geriatric Assessment Matters
- Identifies hidden health issues: Many seniors have undiagnosed conditions that contribute to decline – depression, hearing loss, cognitive impairment, and more.
- Prevents functional decline: Early intervention can maintain or improve independence.
- Reduces unnecessary hospitalisations: By addressing root causes, CGAs reduce the risk of hospital readmissions.
- Improves medication safety: Reduces polypharmacy and harmful drug interactions.
- Enhances quality of life: By addressing the person as a whole, not just their diseases.
- Supports caregivers: Provides resources and support for those providing care.
Comprehensive Geriatric Assessment in India
- Availability: CGAs are available in major hospitals with geriatric departments – AIIMS (Delhi), NIMHANS (Bangalore), PGIMER (Chandigarh), and many state-level medical colleges.
- National Programme for Health Care of the Elderly (NPHCE): The government program aims to provide CGA-like services at district hospitals and primary health centres.
- Private geriatric clinics: Many private hospitals in metropolitan cities offer geriatric assessments. Costs vary.
- Government schemes: Ayushman Bharat covers some geriatric services, but coverage varies by state.
- Telehealth: Some aspects of CGA can be done via telemedicine, especially cognitive and social assessments – useful for seniors in remote areas.
Frequently Asked Questions
Who needs a comprehensive geriatric assessment?
A CGA is particularly valuable for seniors who:
- Have multiple chronic conditions (3 or more).
- Are taking 5 or more medications (polypharmacy).
- Have had recent falls or functional decline.
- Are experiencing memory problems or confusion.
- Have depression or anxiety.
- Need support with daily activities.
- Have been recently hospitalised.
How long does a comprehensive geriatric assessment take?
A complete CGA can take 1-3 hours, often spread over two or more visits. Some assessments (like cognitive and functional testing) may take additional time. The interdisciplinary nature of the assessment means that you'll meet with multiple professionals.
Is a CGA covered by insurance in India?
Some health insurance policies cover geriatric assessment. Check with your insurance provider. Under the Ayushman Bharat scheme, some geriatric services are covered – but check the specific benefits available in your state.
Can I get a CGA for a family member who is homebound?
Some hospitals and geriatric services offer home-based assessments. Ask your local hospital about home visit services. Telehealth may also be an option for parts of the assessment.
What is the difference between a CGA and a regular check-up?
A regular check-up focuses on diagnosing and treating diseases. A CGA focuses on understanding the whole person – including their functional ability, mental health, social support, and environment. The goal is to create a comprehensive care plan, not just to identify disease.
📋 Understanding the Whole Person – The Heart of Geriatric Care
A comprehensive geriatric assessment is not just a test – it's a commitment to understanding the senior as a whole person. It recognises that health in older age is influenced by medical, psychological, social, and environmental factors – and that caring for seniors requires a holistic, team-based approach.
📌 If you're a senior or caring for one, ask your doctor about a CGA. It could be one of the most important health investments you make.
