The Shift from Traditional Exams to Comprehensive Geriatric Assessment
For older adults, a simple, problem-focused medical evaluation often falls short. The complexities of aging, with its overlapping chronic conditions, cognitive changes, and potential for polypharmacy, demand a more holistic view. This is where the Comprehensive Geriatric Assessment (CGA) comes in—a systematic, interdisciplinary approach designed to identify the full spectrum of an older person's needs. The CGA moves beyond a list of diagnoses to focus on functional capacity, quality of life, and the interaction of medical issues with psychosocial and environmental factors. It is this integrated, systematic approach that provides the framework for all other recommended actions, including the most critical one: a thorough medication review.
The Cornerstone of Care: A Detailed Medication Review
Among the many facets of a geriatric assessment, the medication review is arguably the most crucial recommended action, directly addressing potential issues that can significantly impact health. Many older adults take multiple medications prescribed by different doctors, along with over-the-counter drugs and supplements. This practice, known as polypharmacy, is a serious risk factor for adverse drug reactions, drug-drug interactions, and reduced quality of life. A comprehensive medication review should involve gathering a complete list of all substances the patient is taking and scrutinizing it for potential problems. Clinicians can use specific criteria, such as the American Geriatrics Society's Beers Criteria, to identify potentially inappropriate medications for older adults.
Key steps in a thorough medication review include:
- Gathering a complete medication history: Include all prescribed medications, over-the-counter drugs, vitamins, herbal remedies, and supplements.
- Assessing dosing schedules: Check for potential over- or under-dosing, and evaluate the patient's ability to adhere to complex schedules.
- Checking for drug interactions: Review for drug-drug, drug-disease, and drug-food interactions.
- Evaluating appropriateness: Determine if each medication is still necessary and effective, or if it might be causing adverse side effects masquerading as new symptoms.
- Aligning with patient goals: Discuss with the patient their preferences and goals for treatment, particularly regarding medications that manage symptoms but may have side effects.
Assessing Functional and Cognitive Status
Beyond the medication review, a geriatric assessment includes a deep dive into functional and cognitive health. Functional status is a key predictor of an older adult's independence and overall well-being.
Functional Status Evaluation
- Activities of Daily Living (ADLs): These are basic self-care tasks like bathing, dressing, eating, and toileting. Standardized scales, such as the Katz Index, can provide a baseline.
- Instrumental Activities of Daily Living (IADLs): These are more complex activities needed to live independently, such as managing finances, preparing meals, and using the telephone. The Lawton IADL scale is a common tool for this assessment.
Cognitive and Mental Health Screening
- Cognitive Function: Screening for cognitive impairment is a standard part of geriatric care. Tools like the Mini-Cog test can quickly assess memory and executive function. More extensive testing, such as the Montreal Cognitive Assessment (MoCA), may be warranted if initial screening suggests issues.
- Mood: Depression is common among older adults and is often underdiagnosed. Tools like the Geriatric Depression Scale (GDS) can effectively screen for mood disturbances.
The Importance of Environmental and Social Factors
A geriatric assessment is not complete without considering the patient's living environment and social support system. These factors can have a profound impact on an older adult's health and safety.
- Falls Risk Assessment: Given that falls are a leading cause of injury in older adults, a simple gait assessment, such as the Timed Up and Go (TUG) test, is recommended annually for those over 65.
- Socio-Environmental Circumstances: Evaluating the safety and convenience of the home, as well as the strength of the patient's social network, is crucial for developing an effective care plan.
Comparison: Standard Exam vs. Comprehensive Geriatric Assessment
| Feature | Standard Medical Exam | Comprehensive Geriatric Assessment (CGA) |
|---|---|---|
| Focus | Problem-oriented, focusing on acute illness and specific symptoms. | Holistic and multidimensional, focusing on overall function and well-being. |
| Scope | Often limited to the physical complaint presented by the patient. | Covers physical health, functional ability, cognitive and mental health, medication use, and social/environmental factors. |
| Team | Typically involves a physician and possibly a nurse. | A multidisciplinary team, potentially including a physician, nurse, social worker, pharmacist, physical therapist, and occupational therapist. |
| Patient Involvement | Patient typically answers questions about the chief complaint. | Patient and family/caregivers are actively involved in the diagnostic and care planning process. |
| Outcomes | Treatment plan for the specific medical condition. | Coordinated, long-term care plan addressing multiple issues and focused on patient-centered goals. |
Tailored Communication and Ongoing Support
Effective communication is paramount throughout the assessment process, especially for older adults who may have sensory or cognitive impairments. Speaking clearly and at a normal pace, using simple language, and writing down key points are essential practices. The assessment is not a one-time event but a continuous process. Regular reviews and monitoring are necessary to adapt the care plan as the older adult's needs evolve over time.
By integrating a detailed medication review and a comprehensive, multidimensional approach, healthcare providers can gain a deeper understanding of an older adult's health, optimize their treatment plan, and significantly improve their quality of life.

This comprehensive strategy ensures that care is both effective and respectful of the individual's unique needs, contributing to better outcomes in healthy aging.
