What is a Comprehensive Geriatric Assessment?
A Comprehensive Geriatric Assessment (CGA) is a multi-dimensional diagnostic and therapeutic process designed to determine an older person's medical conditions, mental health, functional capacity, and socio-environmental circumstances. Unlike a standard checkup, which focuses primarily on the diagnosis and treatment of acute medical issues, a CGA takes a more holistic view of the individual. A team of healthcare professionals, including doctors, nurses, and social workers, collaborate to create a personalized plan aimed at improving health and maintaining independence.
The Multidisciplinary Team at the Core of a CGA
One of the key distinctions of a CGA is the use of a multidisciplinary team (MDT). This approach brings together diverse perspectives and expertise to provide a more complete picture of an older adult's health.
A typical MDT may include:
- Geriatrician: A medical doctor specializing in the care of older adults, overseeing the entire assessment process.
- Registered Nurse: Manages medication review, monitors vitals, and provides patient education.
- Social Worker: Assesses social support networks, financial resources, and community services.
- Physical Therapist: Evaluates mobility, balance, and fall risk.
- Occupational Therapist: Assesses instrumental activities of daily living (IADLs) and recommends home modifications.
- Pharmacist: Reviews all medications to identify potential adverse effects, interactions, or polypharmacy.
- Dietitian/Nutritionist: Screens for malnutrition or nutritional risk.
This collaborative effort ensures that no stone is left unturned in understanding the patient's overall health and well-being. By pooling their expertise, the team can identify issues that a single provider might miss.
Major Domains Evaluated in a CGA
A CGA is structured around several key domains, each thoroughly evaluated to provide a complete picture of an individual's health.
Functional Status Assessment
Functional ability refers to a person's capacity to perform tasks essential for daily living and independence. This is a critical component of the CGA.
- Activities of Daily Living (ADLs): Basic self-care tasks such as eating, dressing, bathing, and toileting.
- Instrumental Activities of Daily Living (IADLs): More complex tasks necessary for independent living, including managing finances, shopping, and preparing meals.
- Mobility and Balance: Evaluates gait, risk of falls, and mobility challenges. Tools like the Timed Up and Go Test are often used.
Cognitive and Mental Health Evaluation
Cognitive and psychological issues are common in older adults and can significantly impact their quality of life.
- Cognitive Function: Screens for cognitive impairment, including dementia. Instruments like the Mini-Mental State Examination (MMSE) or Montreal Cognitive Assessment (MoCA) may be used.
- Mental Health: Assesses for mood disorders such as depression and anxiety, which are often overlooked in older adults. The Geriatric Depression Scale (GDS) is a common screening tool.
Medical and Physical Health Review
This domain covers the traditional aspects of a medical examination, but with a focus on geriatric-specific concerns.
- Chronic Conditions: Reviews all medical history, past and present illnesses, and ongoing conditions.
- Polypharmacy: Assesses for the use of multiple medications, which is a significant risk factor for adverse drug reactions and falls in older adults.
- Nutritional Status: Screens for malnutrition or unintentional weight loss, which can be signs of underlying health problems.
- Sensory Impairment: Checks for vision and hearing problems, which can be linked to cognitive decline and social isolation.
- Geriatric Syndromes: Identifies conditions common in older adults, such as incontinence, delirium, and sleep disorders.
Socio-Environmental Assessment
An individual's social support system and living environment heavily influence their health and independence.
- Social Support: Evaluates the patient's social network, including family, friends, and availability of caregivers.
- Financial Resources: Considers the patient's financial situation and access to necessary services.
- Home Safety: Assesses the home environment for hazards that could lead to falls or other injuries.
CGA vs. Standard Physical Exam: A Comparison
| Feature | Comprehensive Geriatric Assessment (CGA) | Standard Physical Exam |
|---|---|---|
| Purpose | Holistic view to maximize health and independence | Hands-on checkup to address immediate health concerns |
| Focus | Functional ability, mental health, social situation, environment | Diagnosis and treatment of acute medical conditions |
| Approach | Multidisciplinary team (geriatrician, social worker, therapists) | Single practitioner (e.g., primary care physician) |
| Duration | Often takes multiple visits or involves complex screening | Usually a single appointment |
| Outcome | Coordinated, long-term care plan | Immediate treatment plan for current issues |
The Impact and Benefits of a CGA
Implementing a CGA can significantly impact the health outcomes for older adults. By identifying issues early and creating a coordinated plan, it can lead to:
- Improved Quality of Life: By addressing mobility, mental health, and social support, CGAs can enhance overall well-being.
- Reduced Hospitalization Rates: Tailored interventions and medication management can prevent avoidable hospital visits.
- Maintained Independence: By focusing on functional status and home safety, a CGA helps seniors continue living independently for longer.
- Better Medication Management: Reviews can reduce the risk of adverse drug events from polypharmacy.
- Enhanced Treatment Adherence: By addressing psychosocial barriers, CGAs can increase a patient's adherence to their care plan.
- Increased Patient Satisfaction: Patients often feel more heard and supported due to the comprehensive and team-based approach.
Who Needs a Comprehensive Geriatric Assessment?
While not all older adults require a full CGA, it is highly recommended for those with multiple chronic conditions, unexplained weight loss, functional decline, or complex medication regimens. Families who have concerns about a loved one's safety or well-being can also request an assessment. Patients with stable health and no significant chronic issues may not need a full CGA. However, routine checkups are still important for monitoring health over time.

Conclusion: A Proactive Approach to Healthy Aging
The comprehensive geriatric assessment is a powerful tool for proactive senior care, moving beyond the traditional reactive medical model. By evaluating the full spectrum of a person's health—functional, cognitive, medical, and socio-environmental—it enables a multidisciplinary team to create a personalized, effective, and coordinated care plan. The result is not just a longer life, but a better quality of life, with greater independence, improved health outcomes, and a stronger support system. Ultimately, a CGA represents a vital step towards ensuring the well-being of our aging population.
