Falls and Fall Prevention in the Elderly DORON GARFINKEL, M.D. HEAD, GERIATRIC PALIATIVE DEPARTMENT SHOHAM GERIATRIC MEDICAL CENTER PARDES – HANA, I S R A E L
Falls in the Elderly Overview • Prevalence • Clinical Importance • Risk Factors & Etiology • Evaluation • Prevention & Management • Falls & restraint use • Summary
Prevalence • 30% of those over 65 fall annually • Half are repeat fallers • Falls go up with each decade of life • Over half of those in nursing homes and hospitals will fall each year
FALLS - INCIDENCE • The incidence of falls increase with age • Each year 30 - 40% of community-dwelling persons > 65 years old have a fall. • The annual incidence of falls among people who experienced a fall in the previous year, is almost 60%. • 25% - AGE 65 – 74, 33% - AGE > 75 • 120% AGE > 80 ( > ONE FALL / Year)
Clinical Importance Impact of Hip Fractures • 1% of falls result in hip fracture • $2 billion + in medical costs annually • 25% die within 6 months • 60% have restricted mobility • 25% remain functionally more dependent
Falls Cause Morbidity & Mortality • Mortality: indirect effects • Fractures: 6% of falls • Soft tissue injury, head injury, subdural hematoma • Fear of falling can result in decreased activity, isolation, and further functional decline • Nursing home placement & loss of independence
FALLS -A LEADING CAUSE OF MORBIDITY, DISABILITY & DEATH • Complications resulting from falls are the leading cause of death from injury in adults aged 65 and older. • Fear, Loss of Confidence • Decreased Functioning • Dependency • Physical Trauma - 10% • FRACTURES - 5%- 15%
Risk Factors & Etiology Falls are Multifactorial Intrinsic Factors Extrinsic Factors Medications Improper use of assistive devices Environment Medical conditions Impaired vision and hearing Age related changes FALLS
Age - Related Changes • Neurologic • Increased reaction time • Decreased righting reflexes • Decreased proprioception • Vision Changes • Decreased accommodation & dark adaptation • Decreased muscle mass
Age - Related ChangesG A I T • Slower gait • Decreased stride length & arm swing • Forward flexion at head and torso • Increased flexion at shoulders and knees • Increased lateral sway
D y s m o b i l i t y • Dysmobility and falling closely related • 15% of those over 65 have trouble walking • 1/4 men and 1/3 women over age 85 have difficulty with walking • 2/3 of people in hospital or NH unable to ambulate without assistance
Risk Factors for Falls Risk FactorOR • 28 • Cognitive Impairment 5 • Lower extremity problem 4 • Pathologic Reflex 3 • Foot Problems 2 • > balance/gait problems 1.9 Sedative use Tinetti NEJM 1988
Common Pathologies associated with Falls • Ophthalmologic diseases • Arthritis • Foot problems • Neurologic illness • Parkinson’s & related disorders • Strokes • Peripheral neuropathy • Dizziness and dysequilibrium
Dizziness: A Multifactorial Syndrome • Vertigo: Posterior CVA/TIA, Cervical • Presyncope: Orthostatic, Dysrythmia, Anemia • Dysequilibrium: Peripheral neuropathy, Visual • Other: Anxiety, depression • In older people, usually multifactorial Tinetti, Annals of Internal Med 2000
Falls in the Community • Accidents/environment 37% • Weakness, balance, gait 12% • Drop attack 11% • Dizziness or vertigo 8% • Orthostatic hypotension 5% • Acute illness, confusion, drugs, decreased vision 18% • Unknown 8% Rubenstein JAGS 1988
Falls in Residential Care • Generalized weakness 31% • Environmental hazard 27% • Orthostatic hypotension 16% • Acute illness 5% • Gait or balance disorder 4% • Drugs 5% • Other or unknown 10% Rubenstein Ann Int Med 1990
Medications and Falls • Sedative-hypnotics, especially long acting benzodiazepines, • Small association between most psychotropics and falls • SSRIs and TCAs both increase falls • Weak association between Type 1A antiarrythmics, digoxin, diuretics, and falls Leipzig JAGS 1999 Thapa NEJM 1998
Evaluation of Falls in the Elderly Medical History • Location & circumstances of Fall • Associated symptoms • Other falls or near falls • Medications (including nonprescription) and alcohol • Injury & ability to get up
Evaluation of Falls in the Elderly Physical Examination • Supine and standing BP - always • Routine physical examination Focus on cardiovascular, MS, neuro, feet • Vision and hearing evaluation • Consider acute medical illness & delirium • Formal gait and balance assessment
Evaluation of Falls: Home Evaluation • Can be performed by nurse, OT, PT, others • Stairs • Lighting • Bathroom • Specific hazards: cords, throw rugs
Evaluation of Falls: Risk Factors for Injury • Osteoporosis assessment • Anticoagulation: Usual benefits outweigh risks unless repeat or high risk faller • Can the person get up from fall? • Is there a way to notify others in case of falling?
Formal Gait Evaluation Get up and Go Test Tinetti Gait & Balance Evaluation (POMA) POMA: Balance Component Sitting (in hard, armless chair) Arising Standing balance (immediate and delayed) Balance with Nudge Balance with Eyes closed Balance with 360 degree turnTinetti JAGS 1986
POMA: Gait Component Initiation Step length and height Step symmetry & continuity Path Stance Ability to pick up speed Tinetti JAGS 1986
Prevention & Treatment • Treat acute injury & underlying medical conditions • Remove unnecessary medications • Rehab, exercises, assistive devices • Correct sensory impairments • Environmental modifications & safety • Evaluate for osteoporosis treatment
Osteoporosis • Calcium and vitamin D for most elders at risk • Dawson-Hughes, NEJM, 1997 • Osteoporosis evaluation and treatment • Thiazides may help slightly • Statins? • Hip protectors appear to protect from hip fractures in those who wear them • Kannus, NEJM, 2000
Risk Factor Modifications for Fractures ChangeEstimated Change in Risk Quit smoking 38% Treat impaired vision 50% Stop sedatives 40% Add 1 Gram Calcium 24% Hip Protectors 50%? Adapted from Steeve Cummings
Falls: Primary Prevention • 301 community dwelling elders with 1+ risk factors for falling • Intervention: adjustment in medications, behavioral instructions, exercise programs aimed at modifying risk factors • One year follow up Tinetti et al. 1994 NEJM
Multifactorial Intervention P = .04 Tinetti et al 1994 NEJM
Exercise Training & Nutrition Fiatarone et al NEJM 1994
Tai Chi and Falling • Atlanta FICSIT Trial • 200 community dwelling elders 70+ • Intervention: 15 weeks of education, balance training, or Tai Chi • Outcomes at 4 months: Strength, flexibility, CV endurance, composition, IADL, well being, falls • Falls reduced by 47% in Tai Chi group Wolf JAGS 1996
Training frail older persons: The New Zealand Study of Women 223 women >80 years Intervention: PT tailored to individual needs, with resistance and balance training Results: Clinical balance, chair rise improved RR for falls .47 (CI .04-.90) RR for injurious falls .61 (.39-.97) Campbell BMJ 1997
Summary • Falls are common in the elderly & may lead to injuries and decline in function • Evaluation should included risk factor assessment, gait assessment, and home assessment • Exercise can improve outcomes • We have no evidence that restraints reduce fall related injuries

HIP FRACTURES - OUTCOMES The death rate attributed to falls also increase with age, reaching at age > 85 – 180 deaths per 100,000 population Hip fractures is the commonest reason for admission of elderly people to an acute orthopedic ward Johnell & Kanis, Osteopor Int 2004; 15: 897 – 902.
HIP FRACTURES - OUTCOMES • Each year, 8% of people > 70 years old reach the Emergancy Room, as a result of Fall - related injuries • Those admitted are hospitalized for an average of 8 days. • These hip fractures may result in .permanent disability accounting for a significant portion of the Global Burden of Disease
HIP FRACTURES - OUTCOMES • Only 25 percent of patients with hip fractures will make a full recovery • 50 percent will need some assistance - cane or walker • 40% will require Long – Term Care (nursing homes & nursing departments) • In the US, the cost of fall-related injuries is estimated as 12,6 billion dollars yearly
