Understanding the Comprehensive Geriatric Assessment (CGA)
A comprehensive geriatric assessment (CGA) is a systematic, multidimensional evaluation that extends beyond a typical medical exam. It is designed for frail or vulnerable older adults and focuses on their overall health, not just a single disease. A CGA explores a person's medical conditions, functional abilities, psychosocial well-being, and environmental factors to develop an integrated and coordinated care plan. This process is different from a routine check-up, emphasizing functional capacity and quality of life to maximize overall well-being.
The Core Members of the Multidisciplinary Team
The complex needs of older adults often exceed the expertise of any single practitioner, which is why a team-based approach is so effective. While the team's composition can vary, a core group of professionals is typically involved:
The Geriatrician: The Team Leader
A geriatrician is a medical doctor with special training in the care and treatment of older adults. They have completed a primary care residency (in internal or family medicine) followed by a fellowship in geriatric medicine. The geriatrician's role is to lead the assessment, synthesize the findings from the team, manage complex medical conditions, review medications, and develop a coordinated treatment plan.
The Geriatric Nurse: The Frontline Assessor
Nurses play a foundational role in the geriatric assessment process. They are often responsible for gathering key health data, observing the patient's condition, coordinating care plans, and educating patients and families. Advanced practice registered nurses and geriatric nurse practitioners, with their specialized training, can also diagnose illnesses and prescribe certain medications, working closely with the physician.
The Social Worker: Addressing Social and Emotional Needs
An integral part of the team, social workers assess the patient's social networks, support systems, emotional health, and financial resources. They help identify and address issues such as social isolation, caregiver burnout, and access to community resources. Their input is crucial for developing a holistic care plan that considers the patient's life circumstances.
The Extended Team: Specialists and Therapists
For many older adults, a more comprehensive assessment is necessary. The core team may bring in additional specialists to address specific issues:
- Physical Therapists: They evaluate mobility, strength, and balance to prevent falls and improve a patient's functional independence.
- Occupational Therapists: These specialists focus on how the patient performs daily activities, such as dressing, bathing, and cooking. They can recommend adaptive equipment or modifications to the home environment to enhance safety.
- Pharmacists: Given that older adults often take multiple medications (polypharmacy), a pharmacist's role is critical. They conduct a thorough medication review to check for adverse effects and dangerous drug interactions.
- Nutritionists: Poor nutrition is a common problem in older adults. A nutritionist assesses the patient's dietary habits and nutritional status to prevent weight loss and other health complications.
- Psychologists or Psychiatrists: These professionals may be involved in assessing cognitive function, mood, and mental health issues like depression and anxiety.
The Assessment Process: A Collaborative Journey
The geriatric assessment is not a one-time event but an ongoing, iterative process. It can occur in various settings, including hospitals, outpatient clinics, or even the patient's home. Here's a general overview of the steps involved:
- Data Gathering: Information is collected through questionnaires, interviews with the patient and caregivers, and direct observation.
- Team Discussion: The multidisciplinary team meets to discuss the findings from each professional's evaluation.
- Care Plan Development: The team creates a goal-oriented management plan that addresses the patient's identified problems across all domains.
- Implementation and Follow-Up: The plan is put into action, with regular monitoring and adjustments based on the patient's progress.
The Difference Between Primary Care and a Geriatric Team
While a primary care physician (PCP) can handle many health concerns for older adults, the comprehensive nature of a geriatric assessment often requires a specialist team. The following table compares the two approaches:
| Feature | Primary Care Physician (PCP) | Geriatric Assessment Team |
|---|---|---|
| Expertise | Broad knowledge, general medical training. | Specialized in the unique health needs of older adults, with additional training. |
| Approach | Often problem-directed, focusing on specific medical issues. | Holistic and multidisciplinary, addressing medical, functional, and psychosocial factors. |
| Conditions Addressed | Common illnesses, everyday health concerns. | Complex, aging-related issues like dementia, falls, and polypharmacy. |
| Team Structure | Typically a single provider, potentially with referrals to specialists. | Coordinated team of professionals working together to create an integrated plan. |
| Patient Focus | All ages. | Frail or vulnerable older persons, usually over age 65. |
Making the Right Choice
The decision of who performs a geriatric assessment depends on the complexity of the patient's needs. If an older adult has multiple chronic conditions, unexplained weight loss, functional decline, or caregiver concerns, a referral to a geriatric assessment team is often the most beneficial approach. This can be a proactive step toward maintaining independence and improving overall quality of life.

Conclusion: A Collaborative Path to Better Health
In summary, the question of who performs geriatric assessments is best answered by understanding the power of collaboration. It is not just one person, but a dedicated team of experts—from geriatricians and nurses to social workers and therapists—who work together to assess the multidimensional aspects of an older person's health. This team-based approach ensures that a coordinated, integrated, and person-centered plan is created, ultimately leading to improved health outcomes, independence, and quality of life for the patient.
