Introduction to Comprehensive Geriatric Assessment
A Comprehensive Geriatric Assessment (CGA) is a multi-dimensional, interdisciplinary process designed to evaluate an older adult's medical, psychosocial, and functional capabilities. Unlike a standard medical exam, a CGA takes a holistic view to maximize overall health and independence. This systematic evaluation is particularly beneficial for frail older adults or those with complex health issues.
The goal of a CGA is to develop a coordinated, person-centered care plan, often involving a team of healthcare professionals. The resulting plan addresses medical needs, goals, preferences, and long-term care requirements.
Domain 1: Medical and Physical Health
This domain addresses age-related health issues and co-morbidities.
Key areas evaluated include:
- Chronic Conditions: Managing multiple chronic illnesses.
- Nutrition: Assessing for malnutrition and dietary adequacy.
- Sensory Impairment: Screening for vision and hearing problems.
- Pain Management: Identifying and managing chronic pain.
- Polypharmacy: Reviewing medications to reduce adverse drug interactions.
Domain 2: Functional Ability
Functional status focuses on an individual's ability to perform daily tasks and maintain independence. It is divided into:
- Activities of Daily Living (ADLs): Basic self-care tasks (bathing, dressing, etc.).
- Instrumental Activities of Daily Living (IADLs): More complex tasks (managing finances, preparing meals, etc.).
Tools like the Katz ADL scale and Lawton IADL scale are used.
Domain 3: Cognitive and Mental Health
Assessing cognitive function and mental well-being is critical. A CGA evaluates:
- Cognitive Function: Screening for impairment using tools like MMSE or MoCA.
- Mental Health: Screening for depression, often using the Geriatric Depression Scale (GDS).
- Delirium Risk: Assessing for factors increasing the risk of acute confusion.
Early detection allows for timely intervention.
Domain 4: Psychosocial Well-being
This domain examines personal circumstances and social support.
- Social Support: Evaluating social networks.
- Caregiver Needs: Assessing potential caregiver burnout.
- Financial Resources: Reviewing financial stability.
- Advance Care Planning: Discussing preferences for future medical care.
Domain 5: Environmental Factors
The living environment influences safety and independence. This domain focuses on:
- Home Safety Assessment: Identifying hazards to reduce fall risks.
- Accessibility and Adaptation: Evaluating home accessibility and recommending modifications.
- Community Resources: Connecting patients with services like transportation or meal delivery.
Comparative Overview of Geriatric Assessment Domains
| Domain | Primary Focus | Key Assessment Areas | Impact on Care Plan |
|---|---|---|---|
| Medical/Physical | Disease management and preventative care | Chronic conditions, medication review, nutritional status, sensory issues | Optimizing medication, managing co-morbidities, preventative health measures |
| Functional Ability | Independence and daily tasks | ADLs (bathing, dressing), IADLs (finances, meals), mobility | Identifying need for assistance, physical therapy, assistive devices |
| Cognitive/Mental | Mental clarity and emotional health | Memory, attention, mood, depression, dementia screening | Early intervention for cognitive decline, mental health support, caregiver education |
| Psychosocial | Social support and emotional well-being | Social network, caregiver support, financial concerns, goals of care | Addressing isolation, planning for future care, supporting caregivers |
| Environmental | Safety and accessibility of living space | Home hazards, fall risks, accessibility, community support | Recommending home modifications, connecting to community resources |
The Integrated Approach for Optimal Care
By assessing these five domains, healthcare professionals can create an integrated and individualized care plan. This multidisciplinary approach leads to better health outcomes, improved quality of life, and a reduction in hospitalizations. It is a proactive, patient-centered approach that prioritizes what matters most to the individual.
Conclusion
The Comprehensive Geriatric Assessment is an indispensable tool in modern senior care, providing a holistic framework for understanding and addressing the multifaceted needs of older adults. By systematically evaluating the five domains, healthcare teams can develop personalized care plans that extend beyond treating a single illness. This approach empowers older adults to maintain their independence, improve their quality of life, and navigate the complexities of aging with greater confidence. For anyone involved in senior care, a deep understanding of these five domains is essential for delivering the highest standard of compassionate and effective care.
