Understanding the Core Components of a Geriatric Examination
Unlike a routine physical, the general examination of geriatric patients is a multi-dimensional and often multi-disciplinary process known as a Comprehensive Geriatric Assessment (CGA). It moves beyond a simple disease-focused approach to consider the whole person, emphasizing functional capacity, quality of life, and personal goals. This holistic view is critical for identifying specific geriatric syndromes and developing a coordinated plan to maximize overall well-being.
Medical and Physical Health Assessment
The medical component of a geriatric examination is a thorough review of the patient's history, current symptoms, and a focused physical assessment. This includes areas particularly relevant to older adults:
- Detailed Medical History: Capturing not just current and past illnesses, but also a history of longevity in the family, recent medical events, and any significant life changes.
- Sensory Evaluation: Screening for vision and hearing impairment, which are common issues in older adults and can affect communication and safety.
- Nutritional Status: Assessing for weight loss, low BMI, and malnutrition risk, often using screening tools like the Mini Nutritional Assessment (MNA).
- Polypharmacy Review: An in-depth evaluation of all medications, including prescriptions, over-the-counter drugs, and supplements, to identify potential adverse effects or interactions.
Functional Status Evaluation
Functional status refers to a person's ability to perform tasks necessary for living independently. This is a central part of the geriatric assessment and is typically divided into two categories:
- Activities of Daily Living (ADLs): Basic self-care tasks essential for independent living, such as bathing, dressing, toileting, and eating.
- Instrumental Activities of Daily Living (IADLs): More complex skills needed for independent functioning, including managing finances, preparing meals, using the phone, and shopping.
Direct observation of the patient's abilities—such as how they walk into the room, stand up from a chair, or unbutton a shirt—can provide valuable insights into their functional status. Standardized tools like the Katz ADL scale and the Lawton IADL scale can be used for a more formal assessment.
Cognitive and Psychological Assessment
The mental health of an older patient is a vital aspect of their overall well-being, considering the high prevalence of conditions like dementia and depression in this population. The assessment includes:
- Cognitive Function: Screening for memory loss, impaired judgment, and other signs of cognitive impairment using tools like the Mini-Cog or Montreal Cognitive Assessment (MoCA).
- Mood Evaluation: Screening for depression and anxiety, often using a tool like the Geriatric Depression Scale (GDS).
- Affect and Behavior: Observing the patient's mood and overall behavior for any signs of neurodegenerative or psychological conditions.
Social and Environmental Factors
An older adult's health is deeply intertwined with their social circumstances and living environment. The assessment covers:
- Social Support: Evaluating the patient's social network, including family, friends, and access to formal or informal care.
- Home Environment: Assessing the home for safety hazards that could contribute to falls or other injuries. A home safety self-assessment can be a useful tool.
- Financial Resources: Understanding potential economic hardship that could impact access to nutrition, housing, or medical care.
- Goals of Care: Having a conversation with the patient about what matters most to them and what their personal goals are for their care and future.
The Importance of a Multidisciplinary Approach
The complexity of geriatric care often requires the expertise of a multidisciplinary team. A CGA facilitates this collaboration, bringing together professionals such as physicians, nurses, social workers, physical therapists, and nutritionists. This team can collectively identify problems, share insights, and coordinate the development and implementation of a goal-oriented care plan. This approach has been shown to improve functional outcomes and reduce hospitalization and mortality rates in frail older adults.

Comparing Standard Exams to Comprehensive Geriatric Assessments
| Aspect | Standard Physical Exam | Comprehensive Geriatric Assessment |
|---|---|---|
| Primary Focus | Organ-system oriented, disease diagnosis | Multidimensional, holistic evaluation of health, function, and environment |
| Scope | Often problem-directed, treats single conditions | Broad, proactive screening across multiple domains (e.g., cognition, function, social) |
| Goal | Treat and manage specific disease states | Maximize functional capacity and quality of life |
| Team | Typically a single physician | Often a multidisciplinary team (physician, nurse, social worker, therapists) |
| Time Commitment | Can be shorter, focused on presenting symptoms | Can be longer, may be spread over multiple visits ('rolling assessment') |
Challenges and Considerations in Geriatric Assessment
Assessing older adults is not without challenges. Some common issues include:
- Atypical Presentation: Older adults may present with atypical symptoms for a given illness, making diagnosis more difficult.
- Multicomplexity: The interplay of multiple chronic conditions and medications requires careful balancing of treatment plans.
- Functional Decline: It can be challenging to differentiate between changes due to normal aging, deconditioning, and specific disease states.
- Patient Goals: It is crucial to engage older adults in setting priorities, especially when not all health states are simultaneously achievable.
Conclusion
The general examination of geriatric patients is a specialized, patient-centered, and often multidisciplinary process. By holistically evaluating an older adult’s medical, functional, cognitive, psychological, and social status, a Comprehensive Geriatric Assessment (CGA) can uncover unrecognized problems and create a coordinated care plan. This proactive approach is instrumental in improving health outcomes, enhancing independence, and ensuring a better quality of life for seniors.
