Study Notes
Geriatrics Overview
- Geriatrics focuses on assessment and treatment of diseases and injuries in individuals aged 65 and older.
- Age-related decline in body systems begins in the late 20s, gradually progressing over time.
Health-Seeking Behavior
- Older adults often avoid medical assistance due to concerns about the cost of prescriptions.
- Common practices to reduce medication costs include skipping doses or halving dosages.
- Many retirees remain in the workforce to supplement income.
Living Arrangements and Independence
- Contrary to stereotypes, many older individuals live independently rather than in nursing homes.
- Some older adults serve as primary caregivers for younger family members.
Mental and Physical Health Risks
- Social isolation increases the risk of substance abuse and self-neglect.
- Caregiving for chronic conditions can be overwhelming, necessitating dependent living arrangements.
Advance Directives and Decision Making
- Mentally competent adults have the right to consent to or decline medical treatment.
- Healthcare proxies may be appointed to make decisions if the patient cannot do so.
Communication with Patients
- Effective communication involves asking open-ended questions and being non-judgmental to build trust.
- Engaging family members can clarify information obtained during patient interviews.
Leading Causes of Death in the Elderly
- Major causes include heart disease, cancer, chronic respiratory diseases, stroke, and Alzheimer's.
- Vulnerability to acute illnesses can escalate issues across multiple organ systems, such as UTIs leading to sepsis.
Physiological Changes with Aging
- Age-related changes in anatomy and physiology do not guarantee disease; many older adults maintain health.
- Decreased reaction time, increased blood pressure, and less flexible muscles are common.
Respiratory System Changes
- Reduced lung capacity and elasticity lead to a decline in oxygen exchange.
- Conditions like pneumonia and chronic lung diseases are leading causes of death among the elderly.
Cardiovascular System Changes
- Decreased cardiac output and ability to respond to stress increase risks for heart disease and strokes.
- Aneurysms, particularly abdominal aortic, pose significant health threats.
Nervous System Changes
- Brain weight reduction heightens the risk of head trauma and impairs cognitive functions like memory and reflexes.
- Sensory deficiencies, including reduced visual acuity and hearing loss, contribute to falls and accidents.
Cognitive Disorders
- Delirium manifests as acute confusion, requiring assessments for various 'hypo' conditions (e.g., hypoxia, hypoglycemia).
- Dementia, particularly Alzheimer’s, progressively impairs cognitive abilities, often not reversing over time.
Musculoskeletal Changes
- Decreases in bone mass lead to osteoporosis and increased fracture risk.
- Kyphosis and arthritis are common complaints, impacting mobility and daily function.
Gastrointestinal Changes
- Sensory declines in taste and smell impact nutrition, leading to digestive issues.
- Dental loss and enzyme declines reduce the ability to metabolize and detoxify properly.
Renal Changes
- Age-related fluctuations in kidney function contribute to electrolyte imbalances and urinary incontinence.
- Increased vulnerability to complications such as hyperkalemia is common.
Immune System Changes
- An aging immune system alters infection response, with older adults presenting atypical symptoms.
- Signs of infection (fever, increased pulse, weakness) may manifest as subtle changes.
Skin Properties
- Decreased collagen and elastin lead to thinner, more fragile skin, increasing bruise risk and slow healing.
- Pressure ulcers can arise from immobility and should be meticulously managed to prevent infection.
Medications and Polypharmacy
- Many older adults take multiple medications, risking confusion and toxicity due to varied schedules and dosages.
- Monitoring prescription dates and adherence to medical regimes is essential to prevent complications.
Geriatrics Overview
- Geriatrics addresses the healthcare needs of individuals aged 65 and older, focusing on disease prevention, assessment, and treatment.
- Age-related decline in physiological functions starts as early as the late 20s and continues progressively through life.
Health-Seeking Behavior
- Older adults may delay seeking medical help due to fears about prescription costs.
- Strategies to manage medication expenses include skipping doses or reducing dosage amounts.
- Economic necessity often drives many retirees to remain employed.
Living Arrangements and Independence
- A significant number of seniors live independently rather than residing in nursing facilities, challenging common stereotypes.
- Some older adults fulfill active roles as primary caregivers for younger family members.
Mental and Physical Health Risks
- Social isolation can lead to increased risks for substance abuse and neglecting personal care.
- Caregiving responsibilities for chronic health issues can be burdensome, leading to the need for supportive living arrangements.
Advance Directives and Decision Making
- Legally competent seniors retain the right to accept or refuse medical treatments.
- Healthcare proxies can be designated to make decisions on behalf of patients who are unable to do so themselves.
Communication with Patients
- Building trust through effective communication is essential; this includes using open-ended questions and a non-judgmental approach.
- Involving family members during patient discussions can help clarify complex information and foster better understanding.
Leading Causes of Death in the Elderly
- Primary causes of mortality in older adults include heart disease, cancer, chronic respiratory diseases, stroke, and Alzheimer's disease.
- Older adults are vulnerable to rapid deterioration due to acute illnesses, with conditions like UTIs potentially leading to systemic complications such as sepsis.
Physiological Changes with Aging
- Age-related anatomical and physiological changes do not automatically equate to illness; many older individuals can remain healthy.
- Common physiological changes include slower reaction times, elevated blood pressure, and reduced muscle flexibility.
Respiratory System Changes
- Aging is associated with reduced lung capacities and elasticity, impairing oxygen exchange efficiency.
- Pneumonia and chronic respiratory conditions are significant contributors to mortality among the elderly population.
Cardiovascular System Changes
- Aging leads to decreased cardiac output and a diminished ability to cope with stress, elevating heart disease and stroke risks.
- The presence of aneurysms, specifically abdominal aortic, poses serious health concerns for older adults.
Nervous System Changes
- Reduction in brain weight increases susceptibility to head injuries and negatively impacts cognitive functions such as memory and reflexes.
- Sensory decline, including poorer vision and hearing, heightens the risk of accidents and falls in older individuals.
Cognitive Disorders
- Delirium is characterized by sudden confusion and requires evaluation for various hypo conditions (e.g., low oxygen, low sugar).
- Dementia, especially Alzheimer's, leads to irreversible cognitive decline, severely affecting overall functioning.
Musculoskeletal Changes
- Aging results in decreased bone density, which increases the risk for osteoporosis and fractures.
- Common age-related issues include kyphosis and arthritis, both of which adversely affect mobility and daily activities.
Gastrointestinal Changes
- Deterioration in taste and smell can negatively impact nutritional intake, leading to digestive problems.
- Loss of dental health and decreased digestive enzyme activity further complicate metabolic and detoxification processes.
Renal Changes
- Aging can result in variable kidney function, leading to electrolyte imbalances and issues such as urinary incontinence.
- Older adults face heightened risks of complications like hyperkalemia due to renal changes.
Immune System Changes
- The aging immune system presents altered responses to infections, with older adults exhibiting non-typical symptoms.
- Subtle indicators of infection may include low-grade fever, increased heart rate, and overall weakness rather than pronounced signs.
Skin Properties
- Reduced collagen and elastin production in older skin leads to fragility, increased bruising, and slower healing processes.
- Immobility can result in pressure ulcers, necessitating careful management to avoid infection and associated complications.
Medications and Polypharmacy
- The prevalence of polypharmacy among older adults can lead to confusion and increased toxicity due to complex medication regimens.
- Regular monitoring of medication schedules and adherence is crucial to prevent adverse health outcomes related to polypharmacy.
