The Core of Interdisciplinary Geriatric Care
Geriatric care for older adults with complex health issues is far from a one-person job. The foundation of this specialized field is the interdisciplinary team, a group of healthcare professionals from various backgrounds who work together to address a patient's multifaceted needs. This collaborative structure moves away from a fragmented, disease-specific approach to a holistic model that considers the patient's entire well-being. By pooling their expertise, members of the geriatric team can develop a comprehensive, coordinated plan of care that optimizes the older adult's health, function, and quality of life.
The team typically includes a geriatrician or primary care physician, nurses, social workers, physical and occupational therapists, pharmacists, and nutritionists. Each member brings a unique perspective, contributing specialized knowledge about the patient's medical, psychosocial, and functional status. This collective expertise is essential for navigating the complexities of geriatric health, from managing multiple chronic conditions (multimorbidity) to addressing cognitive and social issues. The effectiveness of this model relies on clear communication, mutual respect, and a shared commitment to the patient's best interests.
The Comprehensive Geriatric Assessment (CGA)
At the heart of the decision-making process is the comprehensive geriatric assessment (CGA). This systematic evaluation goes far beyond a standard medical exam by examining a broad range of domains that affect an older adult's health. The CGA provides the team with a complete picture of the patient, allowing them to identify treatable problems that might otherwise be overlooked.
Key Domains of the CGA
- Medical Assessment: Review of all diagnoses, medications (including polypharmacy risks), nutrition, and a thorough physical exam.
- Functional Assessment: Evaluation of the patient's ability to perform activities of daily living (ADLs), such as bathing and dressing, and instrumental activities of daily living (IADLs), like managing finances and medication.
- Psychosocial Assessment: Screening for cognitive function, mental health issues like depression and anxiety, and evaluating social support systems.
- Environmental Assessment: Consideration of the patient's living environment, including safety hazards and access to resources.
- Goal and Values Clarification: A crucial step where the team, patient, and family discuss the patient's personal health goals and what matters most to them. This element is paramount to the shared decision-making process.
After each team member conducts their specialized assessment, they come together to present their findings. This cross-functional review of the patient's status forms the basis of the team's consensus-building discussion and eventual care plan.
The Shared Decision-Making Model
In modern geriatric care, the paternalistic model of decision-making is replaced by shared decision-making. This collaborative approach ensures that the patient remains at the center of all choices about their health. The team's role is to act as advisors, providing expert information on options, risks, and benefits, while the patient's role is to express their goals and preferences. This dialogue is particularly vital for older adults who may face trade-offs between different treatment paths.
When cognitive capacity is a concern, family members and designated healthcare proxies play an essential role. The team will work with the surrogate decision-maker to understand the patient's previously expressed wishes (known as 'substituted judgment') or, if those are unknown, to act in the patient's 'best interests'. This is where tools like advance directives and advance care planning become invaluable. They provide a roadmap for the team and family to follow, ensuring the patient's autonomy is respected even when they cannot participate directly in the conversation.

The Role of Consensus in Decision Implementation
Consensus-building is the practical method through which a geriatric team makes and implements decisions. Rather than a single leader dictating the care plan, the team discusses the CGA findings, potential interventions, and the patient's wishes until a collective agreement is reached. This process ensures that the care plan is not only medically sound but also realistic and aligned with the patient's values.
Comparison of Geriatric Decision Models
| Feature | Team Consensus Model | Paternalistic Model | Patient-Centered Model |
|---|---|---|---|
| Key Principle | Collective, interdisciplinary agreement | The clinician knows best | Patient values and goals guide care |
| Role of Patient | Expresses preferences, collaborates on decisions | Passive recipient of care | Active participant, expresses preferences |
| Role of Team | Collaborative, shares expertise, facilitates decisions | Team follows the primary clinician's directive | Team supports and informs the patient's choices |
| Decision Outcome | Coordinated plan reflecting multiple perspectives | Plan dictated by a single authority figure | Plan aligned with the patient's expressed wishes |
Ethical Dimensions in Geriatric Care
Geriatric care is deeply intertwined with ethical considerations. The team must navigate potential conflicts, such as balancing patient autonomy with safety concerns, especially when an older adult's cognitive function is declining. Ethical principles such as beneficence (doing good), non-maleficence (doing no harm), and justice (fair distribution of resources) are constantly weighed. For instance, the team might discuss whether a certain treatment offers more benefit than burden or how to equitably manage resources. When disagreements arise, ethics committees can be consulted to provide guidance and facilitate resolution, ensuring that all decisions are made through a thoughtful and principled process.
Conclusion
For older adults and their families, understanding how do geriatric teams make decisions provides clarity and confidence in the care process. The shift toward an interdisciplinary, consensus-based, and patient-centered approach signifies a major advance in senior care. This method not only leads to more holistic and effective treatment plans but also profoundly respects the autonomy and dignity of the aging individual. By actively participating in the shared decision-making process—asking questions, expressing wishes, and clarifying values—patients and families become empowered partners in a collaborative journey toward better health outcomes. This proactive engagement is the key to ensuring that care is not just received, but truly embraced.
