Introduction to Geriatric Assessment
Geriatric assessment, often referred to as Comprehensive Geriatric Assessment (CGA), is a specialized evaluation process designed to examine the overall health and well-being of older adults. Unlike a typical medical visit that focuses on a single ailment, the CGA takes a holistic view. It identifies specific needs, strengths, and problems that are common in older age and often go unaddressed in standard medical practice. This approach allows healthcare providers to create a tailored care plan that improves health outcomes, enhances quality of life, and promotes independence for as long as possible.
The Core Domains of Geriatric Assessment
The comprehensive geriatric assessment is built on a multidimensional framework, exploring a variety of interconnected domains that influence an older person's health.
Functional Status
This domain assesses an individual's ability to perform daily tasks and maintain independence. It is often divided into two sub-categories:
Activities of Daily Living (ADLs)
These are fundamental self-care tasks crucial for independent living.
- Bathing: The ability to wash oneself.
- Dressing: The ability to put on and take off clothes.
- Toileting: The ability to get to and from the toilet, as well as manage hygiene.
- Transferring: The ability to move from a bed to a chair and back.
- Continence: The ability to control bladder and bowel movements.
- Feeding: The ability to get food into the mouth.
Instrumental Activities of Daily Living (IADLs)
These are more complex, community-oriented tasks that support independent living.
- Using the telephone: The ability to dial and receive calls.
- Shopping: The ability to go to the store and make purchases.
- Food preparation: The ability to plan and cook meals.
- Housekeeping: The ability to perform standard chores.
- Managing medications: The ability to take the correct dosage at the right time.
- Managing finances: The ability to pay bills and manage bank accounts.
Cognitive Function
Cognitive assessment evaluates mental functions such as memory, thinking, and problem-solving. It screens for common issues like dementia, mild cognitive impairment, and delirium.
- Memory: Short-term and long-term recall.
- Orientation: Awareness of time, place, and person.
- Executive function: The ability to plan, organize, and execute tasks.
Mental and Psychological Health
Emotional well-being is a critical component of healthy aging. This domain focuses on identifying and addressing psychological conditions.
- Depression: Screening for mood changes, loss of interest, and sadness.
- Anxiety: Evaluating feelings of worry and restlessness.
- Social Isolation: Assessing the level of social engagement and support.
Medical Health and Comorbidity
This domain involves a thorough review of the patient's physical health, including acute and chronic diseases, vision, hearing, and immunization status.
- Comorbidity: Managing multiple co-existing chronic conditions.
- Polypharmacy: Reviewing all medications to reduce adverse drug interactions.
Social and Economic Circumstances
An older adult's social network and financial stability significantly impact their health. This domain explores:
- Social Support: The availability of family, friends, and community resources.
- Caregiver Burden: The stress and challenges faced by a caregiver.
- Financial Resources: Evaluating the ability to afford necessary care and resources.
Nutritional Status
Poor nutrition is a common and often overlooked problem in older adults. The assessment includes:
- Weight Loss: Unexplained or significant weight loss.
- Dietary Habits: A review of food intake and potential deficiencies.
- Malnutrition: Identifying risks associated with poor diet.
Environmental Assessment
The living environment can present significant risks to an older person's safety. This domain checks for:
- Fall Hazards: Identifying risks like poor lighting, loose rugs, and lack of grab bars.
- Home Safety: Ensuring the home environment is safe and accessible.
Comparison of Comprehensive Geriatric Assessment vs. Standard Evaluation
| Feature | Comprehensive Geriatric Assessment (CGA) | Standard Medical Evaluation |
|---|---|---|
| Scope | Multidimensional and holistic | Organ-specific and symptom-based |
| Focus | Function, quality of life, independence | Diagnosis and treatment of single diseases |
| Team | Multidisciplinary team (geriatrician, nurse, therapist, social worker) | Single physician (or limited specialists) |
| Assessment Tools | Standardized scales (e.g., MMSE, GDS) | Standard physical exam and lab work |
| Outcomes | Prevention, improved function, enhanced well-being | Treatment of illness, symptom management |
| Setting | Often includes a mix of clinic and in-home evaluation | Typically clinic-based |
Why Geriatric Assessment is Essential for Aging Well
Integrating CGA into a senior’s healthcare plan is not just about treating illnesses but about proactively supporting healthy aging. By uncovering hidden problems across functional, cognitive, and psychosocial domains, healthcare providers can implement interventions that prevent falls, reduce hospitalizations, improve mental health, and sustain independence. This forward-looking approach addresses the specific complexities that come with aging, fostering resilience and a better quality of life.

Conclusion
The domains of geriatric assessment provide a powerful framework for understanding and addressing the complex needs of older adults. By comprehensively evaluating functional status, cognition, mental health, medical issues, social support, nutrition, and environment, healthcare teams can move beyond reactive care to deliver person-centered, proactive, and preventative health strategies. This holistic approach is fundamental to promoting not just longevity but a higher quality of life, ensuring that seniors can age with dignity and independence.
