Comprehensive Geriatric Assessment (CGA)

A structured, multidisciplinary evaluation of an older adult's medical, functional, cognitive, psychological, and social status, used to build an individualized care plan. It typically involves a team and focuses on preserving independence rather than treating a single disease.

Related: Geriatric Syndromes, Activities of Daily Living (ADLs)
Geriatric Syndromes

Common clinical conditions in older adults that are multifactorial in origin and not attributable to a single disease, such as falls, delirium, incontinence, frailty, and functional decline. They often overlap and require broad assessment rather than a single-organ approach.

Related: Frailty, Delirium, Comprehensive Geriatric Assessment (CGA)
Frailty

A state of reduced physiological reserve that leaves an older adult more vulnerable to stressors such as illness, surgery, or hospitalization. It is often identified by unintentional weight loss, exhaustion, weakness, slow gait, and low activity.

Related: Sarcopenia, Geriatric Syndromes, Falls Risk Assessment
Sarcopenia

Age-related loss of skeletal muscle mass and strength that impairs mobility and raises fall and disability risk. It is distinct from weight loss alone and is addressed through resistance exercise and adequate protein intake.

Related: Frailty, Gait and Balance Assessment
Activities of Daily Living (ADLs)

Basic self-care tasks a person performs daily, including bathing, dressing, toileting, transferring, continence, and feeding. Difficulty with ADLs signals significant functional dependence and higher care needs.

Related: Instrumental Activities of Daily Living (IADLs), Functional Decline
Instrumental Activities of Daily Living (IADLs)

More complex tasks needed to live independently, such as managing finances, shopping, cooking, housekeeping, using transportation, and handling medications. IADL loss often precedes ADL loss and can signal early cognitive change.

Related: Activities of Daily Living (ADLs), Caregiver Burden
Functional Decline

A measurable loss of ability to perform self-care or independent living tasks, often triggered or accelerated by hospitalization, illness, or immobility. Early mobilization and function-focused care can prevent or reverse part of the loss.

Related: Activities of Daily Living (ADLs), Hospital-Acquired Disability, Sarcopenia
Falls Risk Assessment

A structured evaluation to identify older adults likely to fall, using history of falls, gait and balance testing, medication review, vision and foot checks, and environmental review. Positive screening leads to multifactorial intervention rather than advice alone.

Related: Gait and Balance Assessment, Fear of Falling, Orthostatic Hypotension
Gait and Balance Assessment

Testing of walking pattern, speed, steadiness, and postural control, commonly with a timed walk or sit-to-stand test. Abnormal findings predict falls and functional loss and guide exercise-based interventions.

Related: Falls Risk Assessment, Sarcopenia
Fear of Falling

Persistent worry about falling that leads an older adult to restrict activity and social participation, which paradoxically worsens strength, balance, and fall risk. It is assessed separately from actual fall history and responds to confidence-building exercise programs.

Related: Falls Risk Assessment, Functional Decline
Orthostatic Hypotension

A drop in blood pressure on standing, often defined as at least 20 mmHg systolic or 10 mmHg diastolic within three minutes of rising. It causes dizziness and falls and is frequently linked to dehydration or blood pressure medications.

Related: Falls Risk Assessment, Polypharmacy
Delirium

An acute, fluctuating disturbance of attention and awareness, usually caused by an underlying medical problem, medication, or environmental trigger. It is a medical emergency that is often mistaken for dementia and is preventable with non-drug measures.

Related: Dementia, Anticholinergic Burden, Geriatric Syndromes
Dementia

A chronic, progressive decline in two or more cognitive domains that interferes with independence in daily life. It is distinguished from delirium by its gradual onset and stable or slowly worsening course rather than acute fluctuation.

Related: Delirium, Instrumental Activities of Daily Living (IADLs), Caregiver Burden
Depression Screening in Older Adults

Use of validated tools such as the Geriatric Depression Scale to detect mood disorders, since older adults may present with somatic complaints, withdrawal, or cognitive slowing rather than classic sadness. Untreated depression worsens function, adherence, and mortality.

Related: Delirium, Caregiver Burden
Polypharmacy

Use of multiple medications at once, often defined as five or more, which raises the risk of interactions, adverse effects, and hospitalization in older adults. It warrants periodic review to confirm each drug still has a clear indication.

Related: Beers Criteria, Anticholinergic Burden, Deprescribing
Beers Criteria

An evidence-based list of medications considered potentially inappropriate for older adults because of high risk of harm relative to benefit. It is a decision-support tool, not a prohibition, and should prompt review rather than automatic discontinuation.

Related: Polypharmacy, Deprescribing, Anticholinergic Burden
Anticholinergic Burden

The cumulative effect of medications with anticholinergic properties, which can cause confusion, constipation, urinary retention, dry mouth, and falls. It is a common and reversible contributor to cognitive and functional decline.

Related: Delirium, Polypharmacy, Beers Criteria
Deprescribing

A planned, supervised process of reducing or stopping medications when harms outweigh benefits, such as in frailty, limited life expectancy, or after a goals-of-care change. It involves tapering, monitoring, and communication with the prescribing clinician.

Related: Polypharmacy, Beers Criteria, Advance Care Planning
Adverse Drug Event

An injury or harmful effect resulting from a medication, including falls, bleeding, confusion, or kidney injury. In older adults these are often nonspecific and mistaken for new illness or aging.

Related: Polypharmacy, Anticholinergic Burden
Medication Reconciliation

A formal process of comparing a patient's full medication list across care settings and resolving discrepancies at admission, transfer, and discharge. It prevents omissions, duplications, and dangerous interactions during transitions.

Related: Transitional Care, Polypharmacy, Readmission Risk
Transitional Care

Coordinated actions designed to ensure continuity and safety as a patient moves between settings such as hospital, home, and skilled nursing facility. It includes timely communication, medication reconciliation, and follow-up planning.

Related: Medication Reconciliation, Readmission Risk, Care Coordination
Readmission Risk

The likelihood that an older adult will require rehospitalization soon after discharge, driven by factors such as polypharmacy, functional decline, poor social support, and unclear follow-up plans. It is a key target of transitional care interventions.

Related: Transitional Care, Care Coordination, Social Determinants of Health
Care Coordination

Deliberate organization of patient care activities among multiple providers and settings to avoid gaps, duplication, and error. It is especially important for older adults with multimorbidity and multiple specialists.

Related: Transitional Care, Multimorbidity, Caregiver Burden
Multimorbidity

The coexistence of two or more chronic conditions in one person, common in older adults and often complicated by interacting treatments and competing priorities. Care focuses on function and goals rather than single-disease targets.

Related: Polypharmacy, Care Coordination, Advance Care Planning
Chronic Disease Self-Management

Structured support that helps older adults build skills to manage long-term conditions, such as symptom monitoring, action planning, and problem solving. It improves confidence and reduces avoidable acute care use.

Related: Multimorbidity, Health Literacy
Health Promotion in Older Adults

Activities that maintain or improve well-being and independence, including physical activity, nutrition, immunizations, sensory screening, and social engagement. It is appropriate at every age, including for those with chronic illness.

Related: Immunization in Older Adults, Falls Risk Assessment, Health Literacy
Immunization in Older Adults

Administration of recommended vaccines, such as influenza, pneumococcal, shingles, and COVID-19, based on age and health status. Immunization reduces severe illness and is a core preventive service in geriatric care.

Related: Health Promotion in Older Adults
Health Literacy

A person's ability to obtain, understand, and act on health information to make decisions. Low health literacy is common in older adults and requires plain language, teach-back, and simplified instructions.

Related: Teach-Back Method, Chronic Disease Self-Management, Shared Decision-Making
Teach-Back Method

A communication technique in which the clinician asks the patient to explain information in their own words to confirm understanding. It reveals gaps and corrects misunderstandings without blaming the patient.

Related: Health Literacy, Medication Reconciliation
Advance Care Planning

An ongoing conversation and documentation process in which a person clarifies values, goals, and preferences for future medical care. It may include naming a health care agent and completing advance directives before a crisis occurs.

Related: Advance Directive, Goals of Care, Deprescribing
Advance Directive

A legal document that records a person's wishes about medical treatment or names someone to decide if the person cannot speak for themselves. It takes effect only when decision-making capacity is lost.

Related: Advance Care Planning, Health Care Proxy, Decision-Making Capacity
Health Care Proxy

A person appointed in writing to make medical decisions on behalf of someone who can no longer do so. The proxy should follow the patient's known values and wishes rather than personal preference.

Related: Advance Directive, Surrogate Decision-Making
Surrogate Decision-Making

Making health care decisions for an adult who lacks capacity, using the standard of substituted judgment or, when wishes are unknown, best interest. Surrogates should be supported with clear information and documentation.

Related: Health Care Proxy, Decision-Making Capacity, Elder Self-Neglect
Decision-Making Capacity

A clinical determination that a person can understand relevant information, appreciate consequences, reason about options, and communicate a choice. It is task-specific and does not equal a diagnosis of dementia.

Related: Surrogate Decision-Making, Advance Directive
Goals of Care

The outcomes a patient values most, such as comfort, independence, or longevity, which guide treatment choices. Clarifying them aligns care with patient priorities and reduces unwanted interventions.

Related: Advance Care Planning, Hospice, Shared Decision-Making
Shared Decision-Making

A collaborative process in which clinician and patient discuss options, benefits, harms, and patient values before choosing a plan. It is central to person-centered care for older adults with complex conditions.

Related: Goals of Care, Health Literacy, Advance Care Planning
Hospice

A comfort-focused model of care for people with a serious illness and a limited prognosis, typically defined by a prognosis of six months or less. It addresses physical, emotional, and spiritual needs and includes family support.

Related: Palliative Care, Goals of Care, Pain Assessment in Dementia
Palliative Care

Interdisciplinary care that relieves symptoms and improves quality of life for people with serious illness at any stage, alongside curative or disease-directed treatment. It is not limited to end-of-life care.

Related: Hospice, Goals of Care, Pain Assessment in Dementia
Pain Assessment in Dementia

Use of observation-based tools and caregiver reports to detect pain in people who cannot reliably self-report, looking for facial grimacing, guarding, restlessness, and behavior change. Untreated pain often presents as agitation.

Related: Dementia, Palliative Care
Caregiver Burden

The physical, emotional, financial, and social strain experienced by family or friends providing care. It predicts caregiver illness, nursing home placement, and elder mistreatment, so it should be screened and supported.

Related: Instrumental Activities of Daily Living (IADLs), Elder Mistreatment, Respite Care
Respite Care

Temporary relief for family caregivers, provided in the home, an adult day program, or a facility. It supports caregiver health and helps sustain home-based care.

Related: Caregiver Burden, Care Coordination
Elder Mistreatment

Intentional harm or neglect of an older adult, including physical, emotional, sexual, financial abuse, neglect, and self-neglect. It requires screening, documentation, and reporting under state law.

Related: Elder Self-Neglect, Caregiver Burden, Surrogate Decision-Making
Elder Self-Neglect

An older adult's failure to meet their own basic needs, such as food, hygiene, medication, or safety, often linked to cognitive impairment, depression, or isolation. It is the most common reported form of elder mistreatment.

Related: Elder Mistreatment, Decision-Making Capacity
Social Determinants of Health

Nonmedical conditions that shape health, including income, housing, transportation, food security, and social connection. In older adults they strongly influence medication adherence, safety, and access to care.

Related: Readmission Risk, Care Coordination
Hospital-Acquired Disability

New or worsening loss of function during a hospital stay, often from immobility, sleep disruption, and poor nutrition. It is preventable through early mobilization and minimizing tethers such as catheters and restraints.
