Unit
- Primary aging: refers to the gradual, universal biological changes that occur over time regardless of disease or lifestyle, including reduced skin elasticity, slower nerve conduction, and diminished organ reserve capacity that affects how older adults respond to physical stress or illness.
- Secondary aging: describes changes caused by disease, environmental exposure, or lifestyle factors such as smoking or inactivity, which accelerate decline beyond what primary aging alone would produce and often respond to preventive intervention.
- Cellular senescence: is the process by which cells lose the ability to divide and function normally, contributing to tissue-level decline and reduced capacity for wound healing and immune response in older adults.
- Homeostatic reserve: refers to the body's diminishing capacity to maintain internal stability under stress as it ages, which explains why older adults often decompensate faster during illness, dehydration, or medication changes.
- Multimorbidity patterns: describe the common presence of two or more chronic conditions simultaneously in older adults, requiring coordinated support rather than single-disease-focused approaches typical in younger populations.
- Functional decline trajectory: refers to the pathway through which independence is gradually lost, often nonlinear, with periods of stability interrupted by acute events such as falls or infections that cause sudden drops in capacity.
- Geriatric syndromes: are conditions like frailty, incontinence, and delirium that do not fit a single disease category but result from the interaction of multiple systems weakening together, requiring a holistic support model.
- Successful aging framework: is a conceptual model emphasizing the maintenance of physical function, cognitive engagement, and social participation, used by care planners to set goals beyond simply managing disease.
Scope of Practice
Role: Geriatric Care Support Coordinator
Within scope:
- Explaining general aging concepts to families to set realistic expectations for care planning
- Observing and documenting functional changes for review by clinical staff
- Referring concerning physical changes to a supervising nurse or physician promptly
- Supporting care plans built around maintaining independence and social engagement
Outside scope:
- Diagnosing the cause of a functional decline or cognitive change
- Adjusting treatment plans based on personal interpretation of symptoms
- Communicating a medical prognosis directly to family members
- Determining whether a health change constitutes a medical emergency without clinical consultation
Quick Revision
- Primary aging is universal biological change; secondary aging is influenced by disease and lifestyle and can often be slowed.
- Reduced homeostatic reserve explains why older adults decompensate quickly during illness or stress.
- Multimorbidity and geriatric syndromes require holistic, coordinated support models rather than single-disease approaches.
- Care coordinators observe and document changes but refer diagnostic questions to licensed clinical staff.
