  3. Geriatric MedicinePrinciples/ Falls Learning Objectives: 1. List two characteristics of the geriatric population. 2. Describe two instruments to assess function. 3. Define geriatric syndrome. Name three. 4. List four risk factors for falls. 5. Outline three interventions to reduce fall risk.

  4. Biology of Aging Genetic Oxidative Stress Mitochondrial Dysfunction Hormonal Changes Telomere Shortening (Hayflick Limit) Defective Host Defenses Accumulation of Senescent Cells Harrison on Line

  5. Demographics USA 2020 >65 yo 16% Dependency Ratio-Europe 2050 22% to >50% Harrison on Line Merck Manual Geriatrics

  6. Demographics Over Age 65 40% of Hospital Resources 24% of Office Visits 25% of Prescription Drug Costs 25% of Medicare expenditure in last year of life- Half of this in last 60 days Residents of Nursing Homes Age 65 1% Age 85 17% Merck Manual of Geriatrics

  9. Function: Activities of Daily Living Basic Intermediate Dressing Shopping Eating Housework Ambulating Accounting Toileting Food Preparation Hygiene Transportation

  10. Function with Aging

  11. Principles in a Flash Aging is not a disease. Geriatric conditions are chronic, multiple, multifactorial Reversible conditions are underdiagnosed and undertreated Function and quality of life are critical outcomes Social support and patient preferences are critical aspects Geriatrics is multidisciplinary Cognitive and affective disorders prevalent and undiagnosed at early stages Iatrogenic disease common and often preventable Care is provided in multiple settings Ethical and end of life issues guide practice • www.cha.emory.edu/reynoldsprogram

  12. Clinical Approach Notwhat diseasecaused the problem But what combinationof physiologic change, impairments and diseases are contributing And which onescan be modified Modawal

  13. Geriatric Syndromes Dementia and Delerium Falls Polypharmacy Pressure Ulcers Urinary Incontinence

  14. Mary Anderson This 85 year old widow presents after a fall in the bedroom of the home where she has raised her family and lives independently. She does not know why she fell, was able to ambulate after the fall and presents six hours later with a bruise on her left cheek and an abrasion on the left forearm. Daughter reports occasional confusion and some limitation of activities due to weakness. She reports a fall four months ago. PMH DJD hips and knees with chronic pain Hypertension Macular degeneration Diabetes 2 Urinary urgency and rare incontinence

  15. Medications: Hydrochlorothiazide, Fentanyl patch, KCL,Tylenol, MVI Examination: BP supine 160/88; standing 3 minutes 168/92 Vision 20/50 Chest – rare crackles right base Neuro: absent achilles, romberg normal Gait antalgic secondary to right hip pain Get up and go test: 18 seconds. Uses arms to arise from chair Functional Reach test 5 inches Laboratory: Hemoglobin 11 gm/dl K 3.0 meq/L Glucose 212 mg/dl Creatinine 1.4 mg/dl BUN 24 mg/dl Urinalysis wbc 20, nitrite positive

  16. Questions about Mary Anderson What is the most important risk factor for her recent fall? What is the most important physical examination finding related to her fall? What additional diagnostic studies will be helpful? What is the most important initial step in managing Mary’s fall? What consultations/referrals would be most useful?

  17. Fall “Unintentional coming to rest at a lower position unrelated to obvious intrinsic or environmental factor.” Importance Risk Factors Clinical Assessment History Physical Examination Laboratory Management

  18. Importance Prevalence Ambulatory Adults >65 30% per year Consequences Death Injury Fractures 10-15% Hip 1-2% Long Lie Fear of Falling Reduced Activity/Independence (25%)

  19. Causes Extrinsic Environment Intrinsic Age Gait/Balance Disorder Sarcopenia Vestibular Orthostatic Hypotension Special Senses –Vision/Hearing Disease Dementia Depression Drugs Foot problems Incontinence

  20. Risk Factors Muscle weakness: 4.4 History of falls: 3.0 Gait or balance deficit: 2.9 Use of assistive device: 2.6 Visual deficit: 2.5 Arthritis: 2.4 Depression: 2.2 Cognitive impairment: 1.8 Age over 80 years: 1.7 Mean RR or OR of risk factors for falls from 16 studies Data from AGS Panel on Falls Prevention.
