The Core Concept of Comprehensive Geriatric Assessment (CGA)
The comprehensive geriatric assessment (CGA) is a holistic evaluation for older adults. Unlike traditional medical exams that focus on a single issue, a CGA considers multiple aspects of a person's life to build a complete picture of their health. A team of healthcare professionals conducts this systematic evaluation to identify and address treatable medical and social problems that might be overlooked otherwise. The main goal is to improve the older person's quality of life, maintain independence, and optimize health outcomes.
Key Components of the Assessment
A CGA covers several important areas of a senior's health and life:
- Medical Evaluation: Includes history, physical exam, medication review, and screening for age-related conditions.
- Functional Status: Evaluates ability to perform daily tasks (ADLs) and more complex tasks (IADLs).
- Cognitive and Psychological Health: Screens for cognitive impairment and mental health issues.
- Social and Environmental: Assesses living situation, social support, and safety.
- Nutritional Assessment: Reviews diet and nutritional status.
- Mobility and Balance: Evaluates gait and balance to identify fall risks.
The Multidisciplinary Team Approach
A key aspect of the CGA is collaboration among a team of professionals. This may include: a Geriatrician, Nurses, Physical and Occupational Therapists, Social Workers, Dietitians, and Pharmacists.
The Benefits of a Comprehensive Geriatric Assessment
CGA implementation can lead to several positive outcomes for older adults, including improved health and function, reduced mortality and hospitalization, and effective, personalized care planning.
CGA vs. Standard Clinical Evaluation
A standard clinical evaluation is often problem-focused, addressing a single symptom or disease, while a CGA takes a broader, person-centered approach. For a detailed comparison, see:
| Feature | Standard Clinical Evaluation | Comprehensive Geriatric Assessment (CGA) |
|---|---|---|
| Focus | Organ-specific disease management | Holistic health, function, and well-being |
| Assessment Scope | Primarily medical issues | Medical, functional, cognitive, psychosocial, and environmental |
| Team | Typically a single physician | Multidisciplinary team (physician, nurse, social worker, therapists) |
| Goal | Treating a specific illness or symptom | Improving overall health, independence, and quality of life |
| Outcome | Disease-specific treatment plan | Integrated, person-centered care plan |
| Context | Single visit or series of focused visits | Ongoing, monitored process with follow-ups |
Who Should Have a CGA?
A CGA is most beneficial for older adults who are frail, have multiple chronic conditions, or are experiencing a decline in function. Indicators include frequent falls, unexplained weight loss, cognitive changes, multiple diseases, or needing help with daily tasks.
The Ongoing Process of CGA
The CGA is an continuous process that includes implementing, monitoring, and revising the care plan. This ongoing follow-up is vital for the best long-term outcomes.

Conclusion
In summary, the comprehensive geriatric assessment is a valuable tool in geriatric medicine. It moves beyond a disease-focused model to address the complex needs of older adults. This holistic approach has been shown to improve health, reduce hospitalizations, and enhance quality of life for frail older individuals.
