Beers Criteria

An expert-maintained list of medications considered potentially inappropriate for adults 65 and older, organized by drug class and clinical concern, used to guide safer prescribing and deprescribing decisions.

Related: Potentially Inappropriate Medication, Deprescribing, Anticholinergic Burden
Potentially Inappropriate Medication

A drug whose risks generally outweigh benefits in older adults because of age-related sensitivity, limited evidence, or safer alternatives, prompting review rather than automatic discontinuation.

Related: Beers Criteria, Deprescribing, STOPP/START Criteria
STOPP/START Criteria

A European screening tool pairing explicit indicators for stopping inappropriate medicines (STOPP) with indicators for starting indicated medicines (START), used to structure medication review in older patients.

Related: Potentially Inappropriate Medication, Deprescribing
Deprescribing

The systematic, supervised process of reducing or stopping medications whose harms now exceed benefits, planned with the patient and accompanied by monitoring for withdrawal effects or disease recurrence.

Related: Potentially Inappropriate Medication, Prescribing Cascade, Anticholinergic Burden
Prescribing Cascade

A sequence in which a drug's adverse effect is misread as a new illness, leading to another drug being added, which can compound risk and obscure the original cause.

Related: Deprescribing, Anticholinergic Burden
Anticholinergic Burden

The cumulative effect of multiple medications with anticholinergic activity, which can cause confusion, urinary retention, constipation, dry mouth, and falls in older adults.

Related: Prescribing Cascade, Beers Criteria, Postural Hypotension
Polypharmacy

Use of multiple medications at once, often defined as five or more, and clinically important when the regimen lacks indication, duplicates therapy, or creates interacting risks.

Related: Deprescribing, Medication Reconciliation, Prescribing Cascade
Hyperpolypharmacy

A more extreme medication count, commonly ten or more concurrent drugs, associated with higher risk of adverse events, hospitalization, and functional decline in older adults.

Related: Polypharmacy, Deprescribing
Medication Reconciliation

A structured comparison of a patient's full medication list across care settings to identify omissions, duplications, and dose errors, ideally completed at admission, transfer, and discharge.

Related: Polypharmacy, Care Transition, Adverse Drug Event
Care Transition

The movement of a patient between settings such as hospital, rehabilitation, and home, a period of elevated risk for medication errors, information loss, and unplanned readmission.

Related: Medication Reconciliation, Discharge Counseling
Discharge Counseling

Patient education delivered before leaving a care setting that covers each medication's purpose, dose, timing, expected effects, and whom to contact with problems.

Related: Care Transition, Medication Reconciliation, Health Literacy
Adverse Drug Event

Any harm or injury resulting from a medication, including errors in prescribing, dispensing, or administration, as well as predictable adverse effects and drug interactions.

Related: Medication Reconciliation, Adverse Drug Reaction
Adverse Drug Reaction

A harmful response to a drug at normally used doses, classified as predictable (type A) or unpredictable (type B), and tracked when reporting to safety programs.

Related: Adverse Drug Event, Anticholinergic Burden
Pharmacokinetics

How the body handles a drug over time through absorption, distribution, metabolism, and elimination, each of which can change with aging and disease.

Related: Half-Life, Volume of Distribution, Creatinine Clearance
Pharmacodynamics

How drugs affect the body, including receptor sensitivity and homeostatic reserve, which in older adults can produce stronger or altered responses at the same drug concentration.

Related: Pharmacokinetics, Postural Hypotension
Volume of Distribution

The apparent space into which a drug distributes relative to plasma concentration; age-related changes in body water and fat alter this value and thus loading and maintenance doses.

Related: Pharmacokinetics, Half-Life
Half-Life

The time required for a drug's plasma concentration to fall by half, a value that lengthens with reduced clearance and predicts how quickly effects resolve after a dose change.

Related: Pharmacokinetics, Creatinine Clearance, Volume of Distribution
Creatinine Clearance

An estimate of kidney filtration derived from serum creatinine, age, sex, and weight, used to adjust doses of renally eliminated drugs in older adults.

Related: Half-Life, Pharmacokinetics
Sarcopenia

Age-related loss of skeletal muscle mass and strength that reduces mobility, increases fall risk, and can alter drug distribution and nutritional status.

Related: Frailty, Fall Risk
Frailty

A syndrome of reduced physiologic reserve and vulnerability to stressors, often identified by unintentional weight loss, exhaustion, weakness, slow gait, and low activity.

Related: Sarcopenia, Fall Risk, Comprehensive Geriatric Assessment
Comprehensive Geriatric Assessment

A multidimensional evaluation of medical, functional, cognitive, psychological, and social status that produces an integrated care plan for an older adult.

Related: Frailty, Health Literacy
Postural Hypotension

A drop in blood pressure on standing, commonly defined as at least 20 mmHg systolic or 10 mmHg diastolic within three minutes, increasing fall and syncope risk.

Related: Fall Risk, Anticholinergic Burden
Fall Risk

The likelihood of an unplanned descent to the floor, increased by impaired gait, sedating or hypotensive drugs, vision problems, and environmental hazards, and assessed for prevention planning.

Related: Postural Hypotension, Sarcopenia, Frailty
Orthostatic Syncope

Transient loss of consciousness caused by insufficient cerebral blood flow on assuming an upright posture, often linked to volume depletion or antihypertensive therapy.

Related: Postural Hypotension, Fall Risk
Atrial Fibrillation

An irregular supraventricular rhythm with disorganized atrial activity that raises stroke risk and often requires anticoagulation, rate control, or rhythm control.

Related: CHA2DS2-VASc Score, Anticoagulation
CHA2DS2-VASc Score

A point-based tool estimating stroke risk in atrial fibrillation using age, sex, heart failure, hypertension, diabetes, and prior stroke or vascular disease, guiding anticoagulation decisions.

Related: Atrial Fibrillation, Anticoagulation
Anticoagulation

Therapeutic prevention of clot formation with agents such as warfarin or direct oral anticoagulants, requiring assessment of bleeding risk, renal function, and adherence in older adults.

Related: CHA2DS2-VASc Score, Atrial Fibrillation, Creatinine Clearance
Heart Failure with Preserved Ejection Fraction

A heart failure syndrome with normal or near-normal ejection fraction but impaired filling, common in older adults and managed with diuretics, comorbidity control, and selected newer agents.

Related: Atrial Fibrillation, Postural Hypotension
Delirium

An acute, fluctuating disturbance of attention and awareness often triggered by infection, medications, pain, or metabolic derangement, requiring prompt identification of reversible causes.

Related: Anticholinergic Burden, Dementia, Beers Criteria
Dementia

A progressive decline in cognition that impairs daily function, distinguished from delirium by its chronic course, and affecting medication adherence, capacity, and drug sensitivity.

Related: Delirium, Comprehensive Geriatric Assessment
Serotonin Syndrome

A potentially life-threatening toxicity from serotonergic drugs marked by agitation, tremor, clonus, hyperreflexia, and fever, requiring drug withdrawal and supportive care.

Related: Glycemic Target, Fall Risk
Glycemic Target

An individualized blood glucose goal chosen for an older adult based on life expectancy, comorbidity, and hypoglycemia risk, often relaxed in frail or functionally limited patients.

Related: Hypoglycemia, Frailty
Osteoporosis

Reduced bone mass and disrupted bone structure that raise fracture risk, managed with calcium, vitamin D, weight-bearing activity, and pharmacologic therapy.

Related: Fall Risk, Sarcopenia
Opioid Rotation

Converting a patient from one opioid to another using equianalgesic estimates and then reducing for incomplete cross-tolerance, to improve analgesia or limit toxicity.
