Introduction to Comprehensive Geriatric Assessment
Navigating healthcare for older adults can be complex, often involving multiple specialists and chronic conditions. A standard annual physical may not fully capture the complete picture of a senior's health, which is where a comprehensive geriatric assessment (CGA) comes in. This evaluation goes far beyond a routine check-up, offering a holistic view of an individual's physical, cognitive, social, and functional well-being. It is a critical tool for identifying vulnerabilities, managing complex issues, and developing a person-centered plan to improve overall quality of life.
The Core Components of the Assessment
A CGA is a multi-faceted process, typically conducted by a specialized multidisciplinary team. It systematically evaluates several key domains, with each area providing crucial information that contributes to the final care plan.
Functional Status
This domain assesses an older adult's ability to perform daily tasks. Evaluating functional status is fundamental to understanding a person's level of independence.
- Activities of Daily Living (ADLs): This includes basic self-care tasks such as bathing, dressing, eating, and using the toilet. A decline in ADLs can signal underlying health issues.
- Instrumental Activities of Daily Living (IADLs): These are more complex tasks necessary for independent living, including managing finances, shopping for groceries, preparing meals, and managing medication. Difficulties with IADLs are often an early indicator of cognitive or physical decline.
Medical Evaluation and Polypharmacy
A detailed medical review is a cornerstone of the assessment. This includes a thorough physical exam, a review of medical history, and a specific focus on medication use.
- Medication Review: A pharmacist or physician reviews all medications, including prescriptions, over-the-counter drugs, vitamins, and supplements. The goal is to identify and address polypharmacy—the use of multiple medications—which can increase the risk of side effects, drug interactions, and hospitalizations. This review ensures the medication regimen is both necessary and safe.
- Physical Health Screening: This part of the assessment includes screening for common age-related issues such as vision and hearing impairment, poor nutrition, osteoporosis, urinary incontinence, and fall risk.
Cognitive and Psychological Health
Evaluating mental function and emotional well-being is a critical component, as these areas significantly impact independence and quality of life.
- Cognitive Assessment: Screening for memory loss, dementia, or other forms of cognitive impairment is performed using validated tools like the Mini-Cog or Montreal Cognitive Assessment (MoCA). Early detection is vital for managing cognitive decline and allowing for future planning.
- Emotional Health: Assessment for depression, anxiety, and other mood disorders is also standard, as mental health conditions are common among older adults but are often underdiagnosed.
Social and Environmental Factors
An older adult's living situation and social support network are crucial to their well-being. The CGA examines these factors to ensure the individual has a safe and supportive environment.
- Social Support: This includes evaluating the patient's network of family, friends, and community involvement. It also involves assessing the availability and needs of any caregivers.
- Environmental Assessment: The assessment considers factors in the home environment, such as safety hazards that could contribute to falls, as well as the patient's access to transportation and financial resources.
How a Geriatric Assessment Compares to a Standard Physical
| Feature | Standard Physical Examination | Comprehensive Geriatric Assessment (CGA) |
|---|---|---|
| Focus | Primarily medical health, preventative screening, and acute illness management. | Holistic, multidimensional view including medical, functional, cognitive, and psychosocial factors. |
| Patient Involvement | Patient reports symptoms and concerns. | Patient, family, and caregivers provide input on daily living and function. |
| Medication Review | Typically a quick review of prescription medications. | Detailed reconciliation of all medications (Rx, OTC, supplements) for efficacy and safety. |
| Duration | Generally a standard length of time, often 15-30 minutes. | Can take 90 minutes or longer, or be conducted in several visits for complex cases. |
| Team | Typically led by one primary care physician. | Involves a multidisciplinary team, potentially including geriatricians, nurses, social workers, and therapists. |
| Outcome | Diagnosis and treatment of specific medical conditions. | Integrated care plan focused on maximizing function, independence, and quality of life. |
The Geriatric Assessment Process
The process of a CGA is deliberate and collaborative, moving through a series of steps to ensure a thorough evaluation and effective planning.
- Data Gathering: The process begins by collecting information from the patient, family members, caregivers, and other providers. This often involves questionnaires covering daily activities, health history, and social situation.
- Team Evaluation: A multidisciplinary team reviews the collected data and conducts their specific evaluations. This might include a physical therapist assessing mobility, a neuropsychologist evaluating cognitive function, and a social worker reviewing social and environmental factors.
- Treatment Plan Development: The team collaborates to develop an integrated care plan based on the assessment findings. The plan addresses identified problems and focuses on the patient’s goals and priorities.
- Implementation and Monitoring: The care plan is put into action with ongoing monitoring to ensure its effectiveness. Follow-up appointments are scheduled to track progress and make adjustments as needed.
Preparing for Your Assessment
To get the most out of a geriatric assessment, preparation is key.
- List all medications: Compile a list of all prescriptions, over-the-counter drugs, vitamins, and supplements, including dosages.
- Bring medical history: Have copies of recent test results, hospital summaries, and contact information for all specialists.
- Document symptoms and concerns: Write down any changes in physical or mental health, mobility issues, or difficulties with daily tasks.
- Include caregiver input: If possible, have a family member or caregiver who knows your routines and struggles attend the appointment to provide additional context.
The Benefits of a Comprehensive Approach
Studies show that comprehensive geriatric assessments lead to better patient outcomes, including reduced disability and hospitalization. By focusing on quality of life and independence, this approach empowers older adults to take a more active role in their health management. Early identification of issues like fall risk or cognitive decline allows for timely intervention, often preventing more severe problems down the road.

Conclusion
A geriatric assessment is an invaluable tool in modern healthcare for older adults, providing a clear roadmap for managing complex health needs and optimizing quality of life. By shifting the focus from isolated conditions to the whole person, this collaborative, multidisciplinary process addresses the unique challenges of aging and promotes a healthier, more independent future. Understanding what happens in a geriatric assessment is the first step toward proactive and person-centered care.
