Seminar Outline

Section 1: Comprehensive Geriatric Assessment

The comprehensive geriatric assessment is a multidimensional, interdisciplinary diagnostic process designed to determine the medical, functional, psychological, and social capabilities and limitations of an older adult, with the goal of developing a coordinated plan for treatment and long-term follow-up. The medical domain encompasses the complete list of active diagnoses, current medications with attention to polypharmacy and potentially inappropriate prescriptions, nutritional status including weight trends and dietary adequacy, sensory impairments affecting vision and hearing, and pain assessment. The functional domain evaluates the patient's ability to perform activities necessary for independent living and is arguably the most important predictor of outcomes in older adults. The cognitive domain assesses memory, executive function, judgment, and the capacity to manage complex tasks. The psychological domain screens for depression, anxiety, and other mood disorders that disproportionately affect older adults and often go unrecognized.

Functional assessment is the cornerstone of geriatric evaluation and provides the most clinically useful information for care planning and prognostication. Basic activities of daily living encompass the six fundamental self-care tasks of bathing, dressing, toileting, transferring between bed and chair, maintaining continence, and feeding, and decline in these functions indicates significant dependency requiring hands-on assistance. Instrumental activities of daily living represent more complex tasks necessary for independent community living, including managing medications, handling finances, shopping, cooking, performing housework, using transportation, and using the telephone, and impairment in these functions often represents the earliest detectable decline and may indicate emerging cognitive impairment. Advanced activities of daily living include vocational, recreational, and social activities that contribute to quality of life and community engagement. Assessment should include direct observation of functional tasks when possible, supplemented by patient and caregiver report, and standardized instruments to provide reproducible measurements over time.

Several validated assessment tools facilitate efficient and standardized geriatric evaluation in the primary care setting. The Katz Index of Independence in Activities of Daily Living assesses the six basic ADLs on a scale of zero to six, with each activity scored as independent or dependent, providing a snapshot of basic functional capacity. The Lawton Instrumental Activities of Daily Living Scale evaluates eight IADLs and is more sensitive to early functional decline than the Katz Index. The Timed Up and Go test assesses mobility and fall risk by measuring the time required to rise from a chair, walk ten feet, turn, return, and sit down, with normal performance completed in less than ten seconds and times of fourteen seconds or greater indicating high fall risk. The Mini-Cog is a brief cognitive screening instrument combining three-word recall with a clock drawing task and can be completed in approximately three minutes. The Patient Health Questionnaire-2 and the Geriatric Depression Scale serve as depression screening instruments, with the GDS specifically validated in older adult populations and designed to minimize the influence of somatic symptoms common in this age group.

Establishing goals of care is an essential component of the comprehensive geriatric assessment that ensures treatment decisions align with the patient's values and preferences. Prognosis estimation, though inherently uncertain, informs decisions about the appropriateness of preventive interventions, cancer screening, and the intensity of chronic disease management, as many screening and preventive measures require five to ten years to produce benefit. Functional status and trajectory should be explicitly discussed, focusing on what the patient values most about their daily life and what losses would be most distressing. Values clarification explores the patient's priorities regarding quality versus quantity of life, their willingness to accept burdens of treatment in pursuit of potential benefits, and their preferences regarding the use of life-sustaining technologies. Treatment preferences should be documented and revisited as clinical status changes, recognizing that goals of care are dynamic and may shift in response to acute illness, disease progression, or changes in social circumstances.

Section 2: Polypharmacy

Polypharmacy, conventionally defined as the concurrent use of five or more medications, is present in approximately forty percent of community-dwelling older adults and increases substantially among those with multiple chronic conditions. Hyperpolypharmacy, defined as ten or more medications, affects a significant subset and carries exponentially higher risk. The consequences of polypharmacy extend well beyond simple inconvenience, encompassing adverse drug events which affect approximately fifteen percent of older adults annually, increased fall risk through sedation, orthostasis, and impaired balance, cognitive impairment particularly from medications with anticholinergic properties, drug-drug interactions that become increasingly likely as the medication count rises, and hospitalizations that frequently result from adverse drug effects. The economic burden of polypharmacy is also significant, including both direct medication costs and the downstream expenses of treating adverse events. Each medication added to a patient's regimen should be weighed against these cumulative risks.

Certain medication classes pose disproportionate risk in older adults and should be identified during every medication review. Anticholinergic medications, including diphenhydramine, oxybutynin, tricyclic antidepressants, and first-generation antihistamines, cause confusion, falls, urinary retention, constipation, and dry mouth, and their cumulative anticholinergic burden has been associated with increased long-term dementia risk. Sedative-hypnotic agents, including benzodiazepines and non-benzodiazepine receptor agonists such as zolpidem, increase fall risk, cause cognitive impairment, and are associated with motor vehicle accidents, with risks that increase with age as hepatic metabolism slows and volume of distribution changes. Opioid analgesics contribute to falls, constipation, sedation, and cognitive impairment, and their use should be minimized and carefully monitored. Nonsteroidal anti-inflammatory drugs pose risks of gastrointestinal bleeding, renal insufficiency, fluid retention, and cardiovascular events that are magnified in older adults. Long-acting sulfonylureas, particularly glyburide, carry excessive hypoglycemia risk due to their prolonged duration of action and active metabolites that accumulate with declining renal function.

The American Geriatrics Society Beers Criteria provide a structured, evidence-based reference for identifying potentially inappropriate medications in older adults. The criteria are organized into several categories: medications to avoid in most older adults regardless of diagnosis, medications to use with caution due to potential harms, medications to avoid in the presence of specific diseases or conditions that may be exacerbated, drug-drug interactions of particular concern in older adults, and medications requiring dose adjustment based on renal function. The Beers Criteria are not absolute proscriptions but rather tools to prompt critical evaluation of each medication's risk-benefit ratio in the context of the individual patient. Application requires clinical judgment, as some medications on the Beers list may be appropriate for specific patients when the benefit clearly outweighs the risk and no suitable alternative exists. The STOPP/START criteria represent a complementary European tool that additionally identifies medications that should be started when indicated but are being underutilized.

Deprescribing is the systematic process of identifying and discontinuing medications that are no longer necessary, are causing or may cause harm, or are no longer aligned with the patient's goals of care. The process begins with a comprehensive medication review that includes all prescription medications, over-the-counter products, supplements, and herbal preparations. Potentially inappropriate medications are identified using tools such as the Beers Criteria and clinical judgment, and prioritized for discontinuation based on the severity of potential harm, the strength of the original indication, and patient preference. A deprescribing plan is developed that specifies which medications to discontinue, the tapering schedule when abrupt cessation carries withdrawal risk, and the monitoring plan for detecting disease recurrence or withdrawal effects. Communication with the patient is essential, as many patients are attached to their medications and may resist changes, and framing deprescribing as a positive step toward safety rather than withdrawal of care improves acceptance. Monitoring following discontinuation should assess for both improvement in symptoms attributable to the medication and any recurrence of the condition it was treating.

Section 3: Falls Prevention

Falls represent one of the most consequential geriatric syndromes, affecting approximately one-third of community-dwelling adults over age sixty-five annually and constituting the leading cause of both fatal and nonfatal injuries in this population. Risk factors are categorized as intrinsic and extrinsic. Intrinsic factors include gait and balance impairments, lower extremity weakness, visual deficits including cataracts, glaucoma, and macular degeneration, cognitive impairment that compromises judgment and environmental awareness, peripheral neuropathy affecting proprioception, and vestibular dysfunction. Medication-related risk is a major modifiable contributor, with sedatives, antihypertensives causing orthostatic hypotension, opioids, and anticholinergics being the most frequently implicated classes. Environmental or extrinsic factors include loose rugs, poor lighting, cluttered walkways, stairs without handrails, and inappropriate footwear. Medical conditions such as orthostatic hypotension, cardiac arrhythmias, and orthopedic conditions further increase risk, and multiple risk factors interact synergistically, with the fall rate increasing from eight percent with no risk factors to seventy-eight percent with four or more.

A systematic fall assessment should be conducted for any older adult who reports a fall, presents with injuries consistent with falling, or expresses fear of falling. The history should characterize the circumstances of each fall including the activity at the time, location, time of day, prodromal symptoms such as lightheadedness or palpitations, and any injuries sustained. The frequency and pattern of falls, whether recurrent or isolated, help determine the urgency and breadth of evaluation. A thorough medication review should identify all potentially contributing agents, with particular attention to recently added or dose-adjusted medications. Gait and balance assessment through direct observation is essential, noting step height, stride length, stability, use of assistive devices, and the ability to recover from perturbation. Vision assessment including acuity testing and evaluation for cataracts should be performed. Orthostatic blood pressure measurements taken in the supine, sitting, and standing positions at one and three minutes identify orthostatic hypotension, defined as a systolic drop of twenty millimeters of mercury or greater or a diastolic drop of ten millimeters of mercury or greater. Neurological examination evaluates lower extremity strength, sensation, proprioception, and cerebellar function.

The Timed Up and Go test is the most widely used clinical assessment of mobility and fall risk in primary care. The patient begins seated in a standard armchair, rises without using the arms if possible, walks at a comfortable pace to a line marked on the floor ten feet away, turns, walks back, and returns to a seated position while the clinician times the performance. A time of less than ten seconds is considered normal mobility with low fall risk. Times of ten to fourteen seconds suggest some mobility impairment that warrants further assessment and preventive measures. Times of fourteen seconds or greater indicate high fall risk and should trigger comprehensive fall risk evaluation and multifactorial intervention. Beyond the numeric result, qualitative observation during the test provides valuable information about balance, gait quality, the use of compensatory strategies, and the patient's confidence level. The test should be repeated periodically to monitor for changes in mobility that may signal disease progression or the effects of interventions.

Effective fall prevention requires multimodal interventions addressing the specific modifiable risk factors identified in each patient. Exercise programs incorporating balance training, progressive resistance strengthening, and activities such as tai chi have the strongest evidence for fall prevention and should be prescribed as a core component of every fall prevention plan. Medication review and modification, including reduction or discontinuation of sedatives, unnecessary antihypertensives, and other high-risk agents, can reduce fall risk by approximately twenty-five percent. Vision correction through updated refractive prescriptions and timely cataract surgery addresses a common and treatable contributor. Home safety modifications, ideally assessed through an occupational therapy home visit, include removal of loose rugs, improvement of lighting throughout the home and especially on stairways, installation of grab bars in bathrooms, addition of handrails on stairways, and securing electrical cords. Vitamin D supplementation is recommended for individuals with documented deficiency, as low vitamin D levels are associated with increased fall risk and muscle weakness. Appropriate footwear with low heels, non-slip soles, and adequate support should replace slippers and other unstable options.

Section 4: Cognitive Impairment

Cognitive screening in older adults serves to identify individuals who may benefit from further evaluation, early intervention, and care planning. The Mini-Cog is the most practical bedside screening tool, combining three-word recall and clock drawing to assess memory and executive function in approximately three minutes, with abnormal results defined as recall of zero words or recall of one to two words with an abnormal clock. The Mini-Mental State Examination is a thirty-point instrument assessing orientation, registration, attention, recall, language, and visuospatial function, with scores below twenty-four generally considered abnormal, though educational level significantly affects performance. The Montreal Cognitive Assessment is more sensitive than the MMSE for detecting mild cognitive impairment, using a score of less than twenty-six as the abnormal threshold, and includes more demanding executive function and attention tasks. The USPSTF has found insufficient evidence to recommend routine cognitive screening in asymptomatic older adults. However, screening is appropriate when the patient or family reports memory concerns, when there is observed functional decline, or when cognitive status may affect medical decision-making or medication management.

The major dementia subtypes are distinguished by their clinical features, progression pattern, and underlying pathology. Alzheimer disease is the most common cause, accounting for sixty to eighty percent of dementia cases, and characteristically presents with progressive memory loss as the earliest and most prominent feature, followed by language, visuospatial, and executive function decline over years. Vascular dementia is the second most common type and typically follows a stepwise pattern of deterioration corresponding to sequential cerebrovascular events, with focal neurological signs and prominent executive dysfunction. Dementia with Lewy bodies presents with a distinctive triad of fluctuating cognition, visual hallucinations that are detailed and recurrent, and parkinsonian motor features, and is notable for marked sensitivity to antipsychotic medications which should be avoided. Frontotemporal dementia typically presents at a younger age, between forty-five and sixty-five years, with prominent personality changes, behavioral disinhibition, or progressive language impairment preceding memory loss. Mixed pathology, particularly combined Alzheimer and vascular disease, is common and should be considered when clinical features do not fit neatly into a single category.

Before attributing cognitive decline to a neurodegenerative dementia, reversible causes must be systematically excluded. The mnemonic DEMENTIA provides a useful framework: Drugs and delirium, Emotional disorders particularly depression which can present as pseudodementia with cognitive slowing that improves with antidepressant treatment, Metabolic causes including hypothyroidism and vitamin B12 deficiency, Eyes and ears representing sensory impairments that can mimic or exacerbate cognitive dysfunction, Nutritional deficiencies, Tumor or traumatic brain injury including chronic subdural hematoma in older adults on anticoagulants, Infection including neurosyphilis, HIV, and chronic urinary tract infections in older adults, and Alcohol abuse causing both direct neurotoxicity and nutritional deficiency-related cognitive impairment. The evaluation for reversible causes includes thyroid-stimulating hormone, vitamin B12 level, complete metabolic panel, complete blood count, depression screening, medication review, and neuroimaging with either CT or MRI to evaluate for structural lesions, normal pressure hydrocephalus, and patterns of atrophy that may support a specific diagnosis.

Management of cognitive impairment and dementia is multifaceted, extending well beyond pharmacotherapy to encompass safety planning, caregiver support, and advance care planning. After excluding reversible causes, safety assessment addresses several domains: driving safety, which is often the most contentious issue and requires regular evaluation of cognitive and functional abilities; access to firearms, which should be secured; financial management, which may need to be transitioned to a trusted individual; medication management, which may require supervised administration; and wandering risk, which necessitates identification bracelets and door alarms. Cholinesterase inhibitors including donepezil, rivastigmine, and galantamine provide modest symptomatic benefit in mild to moderate Alzheimer disease and Lewy body dementia. Memantine, an NMDA receptor antagonist, is added for moderate to severe disease. Caregiver education and support is essential, as caregivers face elevated rates of depression, anxiety, and physical illness, and should be connected with resources including the Alzheimer's Association. Advance care planning should be initiated while the patient retains decision-making capacity, as this window closes as the disease progresses.

Section 5: Delirium

Delirium is an acute, fluctuating disturbance of attention and awareness that represents a medical emergency and is fundamentally distinct from dementia in its time course, though both may coexist and underlying dementia is the strongest risk factor for developing delirium. The cardinal features include acute onset over hours to days, a fluctuating course with episodes of lucidity alternating with confusion, inattention as the hallmark cognitive deficit demonstrated by an inability to maintain focus during conversation or follow commands, and disorganized thinking manifested as rambling or illogical speech. Delirium is classified into three subtypes: hyperactive delirium presenting with agitation, restlessness, and sometimes hallucinations, which is the most easily recognized; hypoactive delirium presenting with lethargy, reduced psychomotor activity, and withdrawal, which is more common but frequently missed; and mixed delirium alternating between the two. The Confusion Assessment Method is the most widely used diagnostic instrument, requiring the presence of acute onset with fluctuating course, plus inattention, plus either disorganized thinking or altered level of consciousness.

The causes of delirium are numerous and often multifactorial in older adults, with the mnemonic I WATCH DEATH providing a systematic framework for evaluation. Infection, particularly urinary tract infection and pneumonia, is the most common precipitant. Withdrawal from alcohol, benzodiazepines, or other sedatives must be considered. Acute metabolic derangements including electrolyte abnormalities, hypoglycemia, hyperglycemia, and hepatic or renal failure are frequent contributors. Trauma, including unrecognized fractures and head injury, may precipitate delirium. Central nervous system pathology including stroke, seizure, and meningitis requires exclusion. Hypoxia from any cause including pneumonia, heart failure, and pulmonary embolism can present as delirium. Deficiencies of vitamin B12 and thiamine, particularly in malnourished or alcohol-dependent patients, contribute to confusion. Endocrine disorders including thyroid dysfunction and adrenal crisis may present acutely. Acute vascular events including myocardial infarction and stroke may present atypically in older adults with confusion rather than classic symptoms. Toxins and drugs, including prescribed medications with anticholinergic or sedating properties, are among the most identifiable and modifiable causes.

Prevention of delirium is achievable in hospitalized and at-risk older adults through implementation of evidence-based multicomponent protocols. Orientation strategies including visible clocks and calendars, frequent reorientation by staff and family members, and providing familiar objects from home help maintain cognitive anchoring. Early mobilization with physical therapy beginning as soon as medically feasible prevents the deconditioning and cognitive decline associated with prolonged bed rest. Sleep hygiene protocols that minimize nighttime disruptions, reduce ambient noise and light, and avoid unnecessary nighttime vital signs promote normal sleep-wake cycles. Sensory optimization through ensuring access to glasses and hearing aids prevents sensory deprivation that can precipitate confusion. Maintaining adequate hydration and nutritional intake addresses metabolic contributors. Avoidance of potentially deliriogenic interventions, including minimizing the use of bladder catheters, physical restraints, and medications with anticholinergic or sedating properties, reduces iatrogenic risk. These approaches, collectively known as the Hospital Elder Life Program, have been shown to reduce delirium incidence by approximately thirty to forty percent.

Treatment of delirium centers on identifying and correcting the underlying cause, as delirium is fundamentally a symptom of an underlying medical condition rather than a primary disease entity. The diagnostic evaluation should be thorough and expedited, including basic metabolic panel, complete blood count, urinalysis and culture, chest radiograph, medication review, and additional testing guided by clinical suspicion. All potentially deliriogenic medications should be discontinued or minimized, with particular attention to newly started drugs. Supportive measures include consistent reorientation, maintenance of the sleep-wake cycle, family presence at the bedside, adequate nutrition and hydration, and a calm, well-lit environment. Pharmacologic intervention should be reserved for patients whose agitation poses a safety risk to themselves or staff, and should employ the lowest effective dose of a low-potency antipsychotic such as haloperidol or a second-generation agent such as quetiapine. Benzodiazepines should generally be avoided in delirium except when the etiology is alcohol or benzodiazepine withdrawal. Family education about the nature of delirium, its expected time course, and the importance of reorientation is essential for maintaining a supportive environment.

Section 6: Urinary Incontinence

Urinary incontinence is classified into several types based on the mechanism of urine loss, and accurate classification is essential for directing appropriate treatment. Stress incontinence involves involuntary leakage of urine during activities that increase intra-abdominal pressure such as coughing, sneezing, laughing, and physical exertion, resulting from urethral sphincter incompetence or pelvic floor weakness. Urge incontinence is characterized by a sudden, compelling desire to void that is difficult to defer, resulting in leakage before reaching the toilet, and is caused by detrusor overactivity. Overflow incontinence occurs when the bladder fails to empty completely, leading to continuous or frequent dribbling, and results from either bladder outlet obstruction as in BPH or impaired detrusor contractility as in diabetic autonomic neuropathy. Functional incontinence occurs in patients with normal bladder function but inability to reach the toilet in time due to mobility impairment, cognitive dysfunction, or environmental barriers. Mixed incontinence, the combination of stress and urge components, is common in older women.

Evaluation of urinary incontinence begins with a focused history that characterizes the type, frequency, severity, and impact on quality of life. The pattern of leakage provides the most important diagnostic clue: leakage with exertion suggests stress incontinence, while urgency preceding leakage suggests urge incontinence, and constant dribbling without awareness suggests overflow. A thorough medication review identifies pharmacologic contributors including diuretics that increase urine volume, anticholinergics that impair bladder contractility, sedatives that blunt awareness, and alpha-blockers that may relax the urethral sphincter. Physical examination includes abdominal palpation for a distended bladder, pelvic examination in women to assess for pelvic organ prolapse and vaginal atrophy, and rectal examination in men to evaluate prostate size. Urinalysis excludes urinary tract infection and hematuria as contributing factors. Post-void residual measurement by bladder scan identifies incomplete emptying suggestive of overflow incontinence, with volumes above two hundred milliliters considered significantly elevated. A three-day bladder diary recording fluid intake, voiding times, volumes, and incontinence episodes provides objective data to guide treatment.

Non-pharmacological treatment represents the first-line approach for most types of urinary incontinence and is effective without the side effect burden of medications. Pelvic floor muscle exercises, commonly known as Kegel exercises, strengthen the muscles supporting the urethra and pelvic organs and are effective for both stress and urge incontinence, with optimal results requiring proper technique instruction, daily practice of three sets of ten to fifteen repetitions, and sustained commitment over eight to twelve weeks. Bladder training for urge incontinence involves systematically increasing the intervals between voiding by suppressing the urge and gradually extending the time, ultimately achieving voiding every three to four hours. Timed voiding or prompted voiding is appropriate for functional incontinence and involves toileting at regular scheduled intervals based on the patient's voiding pattern. Fluid management avoids excessive intake, limits fluids before bedtime, and reduces caffeine and alcohol, both of which have diuretic and bladder-irritant properties. Weight loss in overweight and obese patients significantly reduces stress incontinence episodes through decreased intra-abdominal pressure.

Pharmacologic therapy is considered when non-pharmacological measures are insufficient, with medication selection guided by the type of incontinence. Anticholinergic agents, including oxybutynin, tolterodine, solifenacin, and fesoterodine, are the traditional pharmacotherapy for urge incontinence and work by inhibiting detrusor contractions. However, their use in older adults must be carefully weighed against the significant risk of anticholinergic side effects including cognitive impairment, confusion, constipation, dry mouth, and urinary retention, with oxybutynin carrying the highest central nervous system penetration and cognitive risk. Tolterodine and newer agents have relatively less CNS penetration but are not free of cognitive effects. Mirabegron, a beta-3 adrenergic receptor agonist, offers an alternative mechanism for urge incontinence with fewer anticholinergic side effects, making it a preferred option in older adults, though it may increase blood pressure. Anticholinergic medications should be avoided in patients with cognitive impairment or dementia. For stress incontinence refractory to pelvic floor exercises, surgical options including midurethral sling procedures should be discussed, and referral to urogynecology or urology is appropriate.

Section 7: Nutrition and Weight

Malnutrition is a common and frequently underrecognized condition in older adults that significantly increases morbidity, mortality, and healthcare utilization. Contributing factors are multifactorial and include poor appetite related to chronic disease and medication side effects, dental and oral health problems including ill-fitting dentures and xerostomia, depression and social isolation leading to decreased motivation to prepare and consume meals, cognitive impairment affecting the ability to shop for and prepare food, dysphagia limiting dietary variety and intake, financial constraints restricting food access, and medication effects including altered taste sensation and gastrointestinal side effects. The consequences of malnutrition are far-reaching, including sarcopenia with loss of muscle mass and strength, impaired immune function with increased susceptibility to infections, delayed wound healing, increased fall risk due to weakness and balance impairment, and increased surgical morbidity. Screening should be integrated into routine care using weight monitoring and validated tools such as the Mini Nutritional Assessment.

Nutritional evaluation requires systematic assessment of intake adequacy, weight trajectory, and barriers to adequate nutrition. Weight should be tracked longitudinally, with unintentional weight loss exceeding five percent of body weight over six months considered clinically significant and warranting thorough investigation. A dietary history should characterize typical daily intake, meal patterns and frequency, variety and quality of foods consumed, and the ability to shop for and prepare meals. Barriers to adequate nutrition should be specifically identified, including dental problems that may limit food texture choices, swallowing difficulty that may require modified consistency diets, social isolation that removes the social motivation for meal preparation, financial limitations that restrict food access, and transportation barriers that prevent grocery shopping. Depression is a particularly common and treatable cause of poor appetite in older adults and should be screened for in every patient with weight loss. Medical causes of weight loss including malignancy, malabsorption syndromes, hyperthyroidism, and uncontrolled diabetes must be excluded through appropriate laboratory and diagnostic evaluation.

Interventions to address malnutrition should target the identified contributing factors and employ multiple strategies simultaneously. Treating underlying causes, particularly depression, optimizing medications to minimize appetite-suppressing side effects, and managing pain that interferes with eating should be addressed first. Dietary modifications to enhance caloric and protein intake include fortifying foods with additional calories through added butter, cream, cheese, and protein powder, and providing nutrient-dense snacks between meals. Small, frequent meals may be better tolerated than three large meals in patients with early satiety or gastroparesis. Social eating, including congregate meal programs, Meals on Wheels, and family meal planning, addresses the social isolation component. Dental care optimization, including repair or replacement of ill-fitting dentures, treatment of oral infections, and management of xerostomia, can significantly improve the ability to eat comfortably. Referral to a registered dietitian for individualized nutritional counseling and to speech-language pathology for swallowing evaluation and dysphagia management are important interdisciplinary interventions.

Frailty is a clinical syndrome of decreased physiologic reserve and resilience that makes older adults vulnerable to disproportionate health decline from minor stressor events such as a urinary tract infection or a medication change. The Fried phenotype criteria define frailty by the presence of three or more of the following five components: unintentional weight loss of ten or more pounds in the past year, self-reported exhaustion, weakness measured by grip strength, slow walking speed, and low physical activity level. Patients meeting one or two criteria are classified as pre-frail and are at intermediate risk. Frailty is a dynamic state that may be improved with targeted interventions, making early identification valuable. Exercise, particularly combined resistance and aerobic training, is the most effective intervention for frailty and pre-frailty, improving strength, endurance, mobility, and fall risk. Nutritional optimization with attention to adequate protein intake, generally recommended at one to 1.2 grams per kilogram per day, supports the anabolic response to exercise. Addressing underlying contributors including undertreated chronic conditions, medication side effects, depression, and social isolation complements the exercise and nutrition approach.

Section 8: Advance Care Planning

Advance care planning is an ongoing process of communication that helps individuals understand, reflect upon, and discuss their goals and preferences for future medical care, particularly in situations where they may lose the capacity to make decisions for themselves. The core components include values clarification, which explores what gives the patient's life meaning and what constitutes an acceptable quality of life; articulation of goals of care, which translates values into specific treatment preferences for various clinical scenarios; completion of advance directive documents that formalize these preferences in legally recognized formats; designation of a healthcare proxy, also called a durable power of attorney for healthcare, who will make medical decisions if the patient loses decision-making capacity; and for seriously ill patients, physician orders for life-sustaining treatment that translate goals into actionable medical orders. This planning should begin while patients are still healthy and capable of thoughtful deliberation, should involve their chosen proxy in the conversations, and should be revisited whenever health status changes significantly.

The advance care planning conversation requires a skillful communication approach that balances honesty with sensitivity. Opening the discussion with an invitation such as "I would like to talk with you about planning ahead for your healthcare. Is now a good time?" establishes permission and signals respect for the patient's readiness. Exploring values through questions such as "What is most important to you in your life right now?" and "What would be most difficult for you to live without?" reveals the foundational priorities that should guide medical decisions. Discussing clinical scenarios helps translate abstract values into concrete preferences, using questions such as "If you became so ill that you could not speak for yourself, who would you want to make medical decisions for you?" and "If you had a condition that meant you would never regain the ability to recognize your family, what kind of medical treatment would you want?" Identifying and documenting the healthcare proxy is a critical step, as the proxy should understand the patient's values and be willing to make decisions that align with those values even under emotionally difficult circumstances. The conversation should be documented in the medical record and revisited periodically, recognizing that preferences may evolve over time.

Advance directives are the legal documents that formalize an individual's healthcare preferences and proxy designation. The living will specifies the patient's wishes regarding specific medical interventions in defined circumstances, such as the use of mechanical ventilation, artificial nutrition and hydration, dialysis, and cardiopulmonary resuscitation in the setting of terminal illness or permanent unconsciousness. The healthcare proxy or durable power of attorney for healthcare names the individual who is authorized to make medical decisions when the patient lacks decision-making capacity, and is generally considered more important than a living will because it provides a decision-maker who can respond to unforeseen clinical circumstances. Physician Orders for Life-Sustaining Treatment, known as POLST or MOLST depending on the state, are actionable medical orders for patients with serious illness or advanced frailty that translate goals into specific orders regarding resuscitation, medical interventions, and antibiotics. Do-not-resuscitate and do-not-intubate orders address specific preferences regarding cardiopulmonary resuscitation and mechanical ventilation. Completed documents should be readily accessible in the medical record, and copies should be provided to the patient, their proxy, and any involved healthcare facilities.

Communicating prognostic information is an integral part of advance care planning and requires particular sensitivity and skill. Asking permission before discussing prognosis with a question such as "Would it be helpful for us to talk about what to expect with your illness?" respects the patient's right to determine the depth of prognostic discussion they desire. Acknowledging uncertainty is essential, as prognostic estimates are inherently imprecise and should be communicated using ranges rather than specific timeframes, such as "months to a year" rather than exact dates. Prognostic information should be aligned with goals of care by explicitly connecting the expected trajectory to treatment decisions, helping patients and families understand how the prognosis affects the reasonableness of various interventions. Maintaining hope while being honest is not contradictory, as hope can be redirected from cure to comfort, function, and meaningful time with loved ones. Emotional support should be provided after delivering prognostic information, with explicit acknowledgment of the difficulty of the conversation and assessment of the patient's and family's emotional response, while ensuring that the door remains open for future discussions as the clinical situation evolves.

Section 9: Caregiver Support

Family caregivers provide the vast majority of long-term care for older adults in the United States, with an estimated fifty-three million Americans serving in a caregiving role and providing care valued at hundreds of billions of dollars annually. The burden of caregiving extends across physical, emotional, and financial dimensions. Physical strain results from the demanding tasks of lifting, transferring, bathing, and providing round-the-clock supervision, often performed by caregivers who themselves have chronic health conditions. Emotional burden includes grief over the progressive loss of the person they knew, guilt over perceived inadequacy, frustration with behavioral symptoms, social isolation as caregiving restricts outside activities, and the constant stress of vigilance. Financial impact includes lost wages from reduced employment, direct out-of-pocket expenses for care supplies and services, and long-term effects on retirement savings and career advancement. The clinician has a responsibility to recognize that the caregiver is also a patient deserving of attention and should actively inquire about caregiver well-being at every visit involving a dependent older adult.

Assessment of caregiver burden should be conducted systematically and with compassion. The evaluation should characterize the scope of care tasks being provided, including personal care, medication management, meal preparation, transportation, and supervision for safety. The time commitment should be quantified, as many caregivers provide forty or more hours of care per week while simultaneously maintaining employment or other responsibilities. The caregiver's own health status must be assessed, as caregivers experience higher rates of depression, anxiety, cardiovascular disease, and immune dysfunction compared to non-caregivers. Emotional impact should be explored through direct questioning about stress, sadness, frustration, and feelings of being overwhelmed. The adequacy of support from other family members, friends, and community resources should be evaluated, as isolated caregivers are at greatest risk for burnout. Financial strain from caregiving expenses and lost income should be acknowledged, as it may prevent access to needed support services.

Interventions to support caregivers should be individualized based on the specific needs and resources identified during assessment. Respite care, which provides temporary relief from caregiving duties, may take the form of in-home respite aides, adult day care programs, or short-term residential respite, and is essential for preventing caregiver burnout. Support groups, both in-person and online, connect caregivers with peers who understand their experience and provide emotional validation, practical advice, and social connection. Education and skills training help caregivers perform care tasks more effectively and with greater confidence, and disease-specific education helps them understand and manage behavioral symptoms such as agitation and wandering in dementia. Community services including home-delivered meals, transportation assistance, adult day programs, and home health aide services can redistribute some of the care burden. Individual counseling for caregivers experiencing significant depression, anxiety, or grief should be offered, with referral to mental health professionals when appropriate.

Screening for elder abuse is an essential component of caring for dependent older adults and should be integrated into routine clinical encounters. Physical abuse manifests as unexplained injuries, bruises in unusual locations, burns, or fractures, accompanied by fearfulness or flinching in the presence of the caregiver. Neglect, which is the most common form of elder abuse, presents as poor hygiene, malnutrition, dehydration, untreated medical conditions, and pressure ulcers in a patient who is unable to care for themselves. Financial exploitation may be suggested by unexplained changes in financial circumstances, missing belongings, or new additions to financial accounts by unfamiliar individuals. Emotional or psychological abuse presents as withdrawal, depression, anxiety, or behavioral changes in the presence of specific individuals. When elder abuse is suspected, the clinician has a legal and ethical obligation to report to adult protective services, as older adults are among the most vulnerable populations and may be unable to advocate for themselves. Documentation should be thorough, including detailed descriptions of injuries, photographs with consent when possible, and the patient's statements in their own words.

Section 10: Preventive Care Modifications

Cancer screening in older adults requires individualized decision-making that balances the potential for early detection against the patient's life expectancy and the time required for screening to produce a net benefit. Colorectal cancer screening is generally recommended through age seventy-five, with individualized decision-making from seventy-six to eighty-five, and discontinuation after eighty-five. Breast cancer screening decisions after age seventy-five should be individualized based on health status, with discontinuation recommended when estimated life expectancy is less than ten years, as the median time for mammographic screening to produce a mortality benefit is approximately ten years. Cervical cancer screening may be discontinued at age sixty-five in women with adequate prior negative screening results. Prostate cancer screening with PSA is generally not recommended in men over seventy due to the high likelihood of overdiagnosis and overtreatment in this population. The overarching principle is that screening should be discontinued when the time horizon to benefit exceeds the patient's estimated life expectancy, when the burdens of screening and follow-up evaluation exceed the potential benefit, or when the patient's goals of care prioritize comfort and quality of life over disease detection.

Immunization recommendations for older adults reflect the increased susceptibility to vaccine-preventable diseases associated with immunosenescence. Annual influenza vaccination is recommended for all older adults, with high-dose or adjuvanted formulations preferred for those aged sixty-five and older due to their enhanced immunogenicity. Pneumococcal vaccination with PCV15 or PCV20 followed by PPSV23 when indicated protects against the leading cause of community-acquired pneumonia in older adults. The recombinant zoster vaccine Shingrix is recommended as a two-dose series for immunocompetent adults aged fifty and older, providing over ninety percent protection against herpes zoster and postherpetic neuralgia. Tetanus-diphtheria-acellular pertussis booster should be given once if not previously received, with subsequent tetanus-diphtheria boosters every ten years. COVID-19 vaccination should follow current guidelines. These vaccinations remain beneficial regardless of age, as the conditions they prevent carry high morbidity and mortality in older adults and contribute to functional decline.

Decisions about preventive care intensity should be explicitly tied to estimates of life expectancy and the time horizon required for specific interventions to produce benefit. For robust older adults who are functionally independent, cognitively intact, and free of life-limiting illness, standard preventive care recommendations should generally be followed. For older adults with limited life expectancy, whether due to advanced chronic disease, significant frailty, or serious comorbidity, the focus should shift toward symptom management, quality of life, and avoidance of burdensome interventions that are unlikely to yield benefit. For frail older adults, an individualized approach is necessary, weighing the potential benefit of each preventive measure against the burden it imposes, with explicit discussion of these considerations with the patient and their family. A useful heuristic is that screening interventions generally require a minimum five-year to ten-year life expectancy to produce net benefit, while immunizations provide benefit within months and remain appropriate even in frail individuals.

Prevention of functional decline is the overarching goal of geriatric preventive care and encompasses strategies that maintain independence and quality of life. Regular physical activity incorporating aerobic exercise, strength training, and balance exercises is the single most effective intervention for preserving functional capacity and has been shown to reduce the risk of falls, maintain cognitive function, improve mood, and reduce the progression of chronic disease. Cognitive engagement through social activities, intellectually stimulating hobbies, and continued learning may contribute to cognitive reserve and delay the clinical manifestation of dementia. Chronic disease management that prevents complications, particularly glycemic control in diabetes to prevent neuropathy, blood pressure control to prevent stroke, and heart failure management to prevent decompensation, directly preserves function. Fall prevention, as discussed earlier, reduces the leading cause of injury-related functional decline in older adults. The comprehensive geriatric approach recognizes that function, not disease, is the ultimate outcome that matters most to patients, and all preventive and therapeutic decisions should be evaluated through this lens.

Summary

• Comprehensive geriatric assessment evaluates six domains: medical, functional, cognitive, psychological, social, and environmental
• ADL assessment uses the Katz Index for basic ADLs and the Lawton Scale for IADLs, with functional status being the most important predictor of outcomes
• Polypharmacy affects forty percent of older adults; use Beers Criteria to identify potentially inappropriate medications and deprescribe systematically
• Falls affect one-third of adults over sixty-five; the Timed Up and Go test identifies high fall risk at fourteen seconds or greater; multimodal prevention is essential
• Cognitive screening with Mini-Cog is rapid; MoCA is more sensitive for mild impairment; always exclude reversible causes before diagnosing dementia
• Delirium is acute and fluctuating with inattention; use the CAM for diagnosis; find and treat the underlying cause; prevent with multicomponent protocols
• Urinary incontinence classification (stress, urge, overflow, functional) guides treatment; pelvic floor exercises are first-line; avoid anticholinergics in cognitive impairment
• Advance care planning should begin while capacity is intact, clarify values, identify a healthcare proxy, and be documented and periodically updated
• Caregiver support requires assessment of burden and connection to resources including respite care; screen for elder abuse at every visit
• Preventive care in older adults requires balancing time to benefit against life expectancy, individualizing screening decisions, and prioritizing function
