Understanding the Purpose of a Geriatric Assessment
A geriatric assessment, often called a Comprehensive Geriatric Assessment (CGA), is more than a standard annual physical exam. It is a systematic process designed to identify and address medical, psychosocial, and functional issues that can be overlooked in routine office visits. The goal is not just to diagnose disease but to develop a holistic, individualized care plan that improves an older adult's overall well-being, independence, and quality of life. By using a team-based approach, it considers the complex interactions between different health domains unique to aging.
The Core Components of a Geriatric Assessment
A comprehensive geriatric assessment examines several key domains to create a full picture of a patient's health. These include:
Functional Status
Functional status is a cornerstone of the geriatric assessment and evaluates a person's ability to perform daily tasks necessary for living independently. This domain is broken down into two parts:
- Activities of Daily Living (ADLs): These are basic self-care tasks. Evaluation includes the ability to perform activities such as:
- Bathing and grooming
- Dressing
- Toileting
- Eating
- Continence
- Transferring (e.g., getting in and out of bed or a chair)
- Instrumental Activities of Daily Living (IADLs): These are more complex tasks that enable independent living within a community. Evaluation includes areas like:
- Managing finances
- Handling medications
- Using the telephone
- Shopping for groceries and other necessities
- Preparing meals
- Doing light housework
Physical Health
This component involves a detailed medical history and a physical examination focused on issues common in older adults. Key areas of concern often include:
- Vision and Hearing: Impairments in these senses are common and can significantly affect functional ability, mood, and safety. Simple screening tests are typically included.
- Nutrition: A nutritional assessment screens for unintentional weight loss, poor appetite, and malnutrition, which can be caused by medical, dental, or psychosocial issues.
- Falls and Balance: Given that approximately one-third of community-living older persons fall at least once per year, this is a critical component. Assessments involve a review of fall history, gait analysis (such as the Timed Up and Go Test), and an evaluation of home safety.
- Chronic Conditions: This involves a review of existing medical problems and comorbidities, assessing their impact on the patient's daily life and treatment options.
Cognitive Health
Cognitive evaluation is essential for screening for and identifying cognitive impairment and dementia. This is typically done using validated screening instruments. Examples include:
- Mini-Cog™: A simple, quick test involving a three-item recall and a clock-drawing task.
- Montreal Cognitive Assessment (MoCA): A more detailed screen that assesses several cognitive domains, including memory, executive functions, and visual-spatial abilities.
Psychological and Mental Health
Emotional well-being is an integral part of healthy aging. The assessment often includes screening for mood disorders like depression, which is prevalent in older adults but often goes undiagnosed. The Geriatric Depression Scale (GDS) is a common tool used for this purpose.
Medication Review (Polypharmacy)
Polypharmacy, the use of multiple medications, is a significant risk factor for adverse drug effects, falls, and hospitalization in older adults. A geriatric assessment includes a comprehensive medication reconciliation to:
- Review all prescribed, over-the-counter, and supplemental medications.
- Identify potentially inappropriate medications based on criteria like the American Geriatrics Society's Beers Criteria.
- Minimize drug-drug and drug-disease interactions.
- Assess medication adherence and potential side effects.
Social and Environmental Factors
The patient's living situation and social support network can profoundly affect their health. This part of the assessment evaluates:
- Social Support: The availability of family, friends, or caregivers to provide assistance.
- Financial Resources: Assessing a patient's ability to afford housing, medications, and other necessities.
- Home Safety: Identifying environmental hazards in the home that could increase the risk of falls.
Geriatric Assessment vs. Standard Physical Exam
To highlight the depth of a geriatric assessment, compare it with a typical annual physical.
| Feature | Standard Physical Exam | Comprehensive Geriatric Assessment (CGA) |
|---|---|---|
| Focus | Primarily on diagnosing and treating acute medical conditions. | Holistic view, including functional, psychosocial, and environmental factors. |
| Domains Covered | Medical history, vitals, general physical exam, and standard lab tests. | Covers all aspects of a physical exam plus functional status (ADL/IADL), cognition, mood, polypharmacy, and social support. |
| Team | Usually a single physician or primary care provider. | A multidisciplinary team may include a physician, nurse, social worker, pharmacist, and physical therapist. |
| Outcomes | Leads to a treatment plan for specific medical issues. | Develops a comprehensive care strategy to maximize independence and quality of life. |
| Time | Shorter duration, often a single visit. | Can involve a series of visits to target different domains, allowing for more detailed evaluation. |
Conclusion: The Path to Optimal Senior Health
The comprehensive nature of a geriatric assessment is its greatest strength, offering a personalized roadmap for navigating the complexities of aging. By moving beyond a simple medical check-up, it empowers older adults to maintain their independence, improve their quality of life, and receive care that truly aligns with their goals.

A proactive approach through a CGA is one of the most effective strategies for promoting healthy and dignified aging.
How to Prepare for Your Geriatric Assessment
- Create a Medication List: Bring a complete, up-to-date list of all medications, including prescriptions, over-the-counter drugs, and supplements.
- Bring a Support Person: A family member or caregiver can provide crucial information and help recall details the patient might forget.
- Use Self-Assessment Tools: Some clinics provide questionnaires beforehand to gather initial data, saving time during the appointment.
- Prepare a Question List: Write down any concerns regarding your health, memory, or daily activities to ensure all your questions are addressed.
- Gather Relevant Medical Records: If you see multiple specialists, bringing recent test results or notes can be helpful for the multidisciplinary team.
