Falls in Elderly Adults

Overview

Falls are one of the most significant and preventable causes of morbidity and mortality in older adults. A fall is defined as an event resulting in a person unintentionally coming to rest on the ground, floor, or other lower level. In elderly patients (≥65 years), falls are rarely due to a single cause but instead represent a complex geriatric syndrome resulting from the interaction of multiple intrinsic and extrinsic risk factors.

Approximately 30% of community-dwelling adults aged 65 years and older fall each year, with this proportion increasing to 50% in those aged 80 and over. [1] Falls are the leading cause of both fatal and non-fatal injuries in this age group, resulting in substantial morbidity, loss of independence, and healthcare costs. Importantly, falls are not an inevitable consequence of aging, and robust evidence demonstrates that multifactorial interventions can reduce fall rates by 20-30% in community-dwelling older adults. [2,3]

The clinical approach to falls in elderly patients must extend beyond injury assessment to include comprehensive evaluation of fall circumstances, multifactorial risk assessment, and implementation of targeted interventions. Evidence-based falls prevention incorporates exercise programmes (particularly strength and balance training), medication review and optimisation, home hazard assessment and modification, cardiovascular evaluation including orthostatic blood pressure measurement, vision assessment, bone health optimisation, and education. [2,3,4]

Epidemiology and Impact

Incidence and Prevalence

Falls are extremely common in older adults, with clear age-related increases in incidence:

Approximately 3 million older adults are treated in emergency departments annually for fall-related injuries in the United States alone. [1] Among those who fall, approximately 20-30% sustain moderate to severe injuries such as hip fractures, head trauma, or lacerations. [1,5]

Morbidity and Mortality

Falls are the leading cause of both fatal and non-fatal injuries in older adults:

• Mortality: Falls account for over 32,000 deaths annually in the US, with fall-related death rates increasing significantly with age. [1]
• Hip fractures: 95% of hip fractures are caused by falls, with 1-year mortality of 20-30% following hip fracture. [7]
• Traumatic brain injury: Falls are the leading cause of TBI in adults ≥65 years. [1]
• Hospitalisation: Falls are the most common cause of trauma admissions in older adults.
• Nursing home admission: Falls and fear of falling precipitate 40% of nursing home admissions. [5]

Psychological Impact

Beyond physical injury, falls have profound psychological consequences:

• Fear of falling: Affects 40-70% of older adults who have fallen, leading to self-imposed functional limitations and activity restriction. [8]
• Loss of confidence: Results in decreased mobility and social isolation.
• Depression and anxiety: Common psychological sequelae of falls.
• Functional decline: Fear-related activity restriction accelerates functional deterioration.

Economic Burden

The economic impact of falls is substantial, with total direct medical costs exceeding $50 billion annually in the United States. [1] Costs include emergency care, hospitalisation, rehabilitation, nursing home care, and long-term disability support.

Pathophysiology and Risk Factors

Normal Balance and Mobility

Maintaining upright posture and safe ambulation requires complex integration of multiple systems:

Sensory Input Systems:

1. Visual system: Provides information about environmental hazards, spatial orientation, and body position
2. Vestibular system: Detects head position and acceleration
3. Proprioceptive system: Provides feedback on joint position and movement

Central Processing:

• Integration of sensory information in the brainstem and cerebellum
• Cognitive processing and attention (frontal lobe executive function)
• Motor planning and coordination

Motor Output:

• Adequate muscle strength (particularly lower limb and core)
• Normal muscle tone and coordination
• Rapid protective responses and postural adjustments
• Appropriate gait pattern

Age-Related Changes

Normal aging produces physiological changes that increase fall vulnerability:

Multifactorial Nature of Falls

Falls in older adults typically result from the interaction of multiple risk factors rather than a single cause. The risk of falling increases exponentially with the number of risk factors present. [9]

Falls History and Clinical Assessment

Structured Falls History

A detailed history is essential for identifying fall mechanisms and risk factors:

Circumstances of Fall

Key Questions:

1. "What were you doing when you fell?"
2. "Where did you fall?"
3. "What time of day?"
4. "Did you trip or slip on something?"
5. "Have you fallen before? How many times in the past year?"

Pre-Fall Symptoms

Loss of Consciousness

• "Did you lose consciousness or black out?"
• "Do you remember the fall and hitting the ground?"
• "Did anyone witness the fall? What did they see?"
• Amnesia for the event suggests loss of consciousness

Post-Fall Events

• Duration on floor ("long lie"): Unable to get up for > 1 hour indicates increased risk of complications (rhabdomyolysis, pressure injuries, hypothermia, dehydration)
• Ability to get up: Reflects functional capacity and strength
• Post-fall confusion: Compare to baseline cognitive function
• Injuries sustained: Lacerations, pain, reduced mobility

Medications

• Complete medication list (prescribed and over-the-counter)
• Recent changes in medications or doses
• Alcohol consumption
• Medication adherence

Medical History

• Previous falls (number, circumstances, injuries)
• Chronic conditions (cardiovascular, neurological, musculoskeletal)
• Urinary symptoms (frequency, urgency, nocturia)
• Visual or hearing problems
• Recent illnesses or hospitalisations

Functional and Social History

• Baseline mobility (independent, uses walking aid, wheelchair)
• Activities of daily living (ADLs): bathing, dressing, toileting
• Instrumental ADLs: cooking, shopping, medication management
• Living situation (alone, with family, home layout)
• Social support and care arrangements
• Fear of falling and activity restriction

Functional Assessment Tools

Timed Up and Go (TUG) Test

Validated tool for assessing fall risk in community-dwelling older adults. [12]

Method:

1. Patient seated in standard chair with armrests
2. On "Go": Stand up, walk 3 metres (10 feet), turn around, walk back, sit down
3. Time the entire sequence
4. Patient may use walking aid if usually required

Interpretation:

• less than 10 seconds: Normal mobility, low fall risk
• 10-12 seconds: Borderline, mild mobility impairment
• > 12 seconds: Increased fall risk, requires intervention [12]
• > 20 seconds: High fall risk, significant mobility impairment

Sensitivity for falls: 47-87% depending on cut-off Specificity for falls: 59-87% [13]

Functional Reach Test

Measures limits of stability and dynamic balance.

Method:

• Patient stands sideways to wall with arm raised to 90°
• Reach forward as far as possible without stepping
• Measure distance reached

Interpretation:

• 25 cm: Low fall risk

• 15-25 cm: Moderate fall risk
• less than 15 cm: High fall risk

Single-Leg Stance Test

Simple bedside test of static balance.

Method:

• Patient stands on one leg for as long as possible (maximum 30 seconds)
• Eyes open, arms at sides or crossed

Interpretation:

• Unable to maintain for ≥5 seconds: Increased fall risk [13]

Berg Balance Scale

14-item objective measure assessing static and dynamic balance (scored 0-56):

• Score less than 45/56: High fall risk
• Each 1-point decrease increases fall odds by 6-8%

Gait Assessment

Observe patient walking:

Normal Gait Features:

• Symmetrical arm swing
• Heel-to-toe contact
• Narrow base of support
• Normal step length and cadence
• Absence of circumduction or scissoring

Abnormal Gait Patterns Associated with Falls:

Cognitive Assessment

• Mini-Mental State Examination (MMSE) or Montreal Cognitive Assessment (MoCA)

Management and Intervention

The evidence strongly supports multifactorial assessment followed by targeted interventions for preventing falls in community-dwelling older adults. [2,3,4]

Acute Management (After a Fall)

Emergency Department/Acute Assessment

1. Stabilisation and Injury Management

• Primary survey: Airway, breathing, circulation (if severe trauma)
• Analgesia: Multimodal approach (paracetamol, nerve blocks); limit opioids
• Imaging and investigation as indicated above
• Treat injuries: Fracture management, wound care

2. Identify and Treat Precipitants

• Infection: Antibiotics for UTI, pneumonia
• Dehydration: IV fluids
• Hypoglycaemia: Glucose replacement
• Acute cardiac event: Appropriate management
• Medication toxicity: Withhold or reduce offending agents

3. Anticoagulation Management

• If significant bleeding on anticoagulation: consider reversal
  • "Warfarin: Vitamin K 5-10 mg IV + 4-factor prothrombin complex concentrate (PCC)"
  • "DOACs: Specific reversal agents (idarucizumab for dabigatran, andexanet alfa for rivaroxaban/apixaban) or PCC"
• Multidisciplinary decision regarding continuing anticoagulation

4. Special Considerations

"Long Lie" (> 1 Hour Unable to Get Up):

• Screen for complications:
  • Rhabdomyolysis (CK, myoglobin, renal function)
  • Pressure injuries
  • Hypothermia
  • Dehydration
  • Aspiration pneumonia
• IV fluids, warming, monitoring

Anticoagulated Patients with Head Trauma:

• CT head is mandatory (even if minor trauma)
• Consider observation 6-24 hours for delayed bleeding
• Neurological observations
• Repeat CT if any deterioration

Falls Prevention: Evidence-Based Multifactorial Interventions

Cochrane systematic reviews demonstrate that multifactorial interventions (individualised assessment with targeted interventions) reduce falls rate by 23% (Rate Ratio 0.77, 95% CI 0.67-0.87) in community-dwelling older adults. [2,3]

Key Principle: Interventions should be tailored to the individual's specific risk factors identified through comprehensive assessment.

---

1. Exercise Interventions

Strongest evidence for falls prevention.

Evidence Base

Cochrane Review (Sherrington 2019, 108 trials, 23,407 participants): [4]

• Exercise reduces rate of falls by 23% (RaR 0.77, 95% CI 0.71-0.83)
• Exercise reduces number of people experiencing falls by 15% (RR 0.85, 95% CI 0.81-0.89)
• Most effective: Balance and functional exercises + resistance training

Effective Exercise Components

Balance and Functional Training:

• Static balance (standing on one leg, progressively challenging)
• Dynamic balance (weight shifting, reaching)
• Tai Chi (moderate-quality evidence for fall reduction) [4]
• Dual-task training (walking while performing cognitive task)

Resistance/Strength Training:

• Progressive resistance exercises for major muscle groups
• Particularly: quadriceps, hip abductors, ankle dorsiflexors, core
• Moderate to high intensity (60-80% 1RM)

Gait Training:

• Improving walking pattern, speed, step length
• Use of mobility aids if appropriate

Recommended Programme:

• Frequency: 2-3 times per week minimum
• Duration: At least 12 weeks, ideally ongoing
• Intensity: Moderate to high challenge to balance; progressive
• Specificity: Balance exercises should be highly challenging [4]

Evidence-Based Programmes:

• Otago Exercise Programme: Home-based strength and balance (30% fall reduction) [4]
• Sunbeam Program: Group-based progressive resistance + balance in residential care (55% fall reduction) [6]

Contraindications/Precautions:

• Unstable cardiac disease
• Uncontrolled hypertension
• Recent fracture or surgery
• Severe osteoporosis (modify exercises)

---

2. Medication Review and Optimisation

Evidence

Medication review with modification or withdrawal reduces falls, particularly when targeting psychotropic medications. [2,10]

Approach

Comprehensive Medication Review:

1. Identify fall-risk medications:

   • Benzodiazepines and sedatives
   • Antipsychotics
   • Antidepressants (particularly TCAs, SSRIs)
   • Opioids
   • Antihypertensives (particularly in presence of orthostatic hypotension)
   • Anticholinergics
   • Anticonvulsants

2. Assess necessity: Is the medication still indicated?

3. Consider alternatives: Non-pharmacological approaches, safer alternatives

4. Dose optimisation: Use lowest effective dose

5. Deprescribing: Gradual withdrawal if appropriate

Polypharmacy:

• ≥4 medications: 1.5-fold increased fall risk
• ≥10 medications: 3-fold increased fall risk [10]
• Systematic reduction where possible

Specific Recommendations:

• Psychotropic withdrawal: Evidence supports reducing or stopping benzodiazepines, antipsychotics in those at high fall risk [10]
• Antihypertensive adjustment: If orthostatic hypotension present, consider dose reduction or switching agents

---

3. Management of Orthostatic Hypotension

Prevalence: 15-30% of community-dwelling fallers. [11]

Non-Pharmacological Interventions (First-Line)

Lifestyle Modifications:

• Adequate hydration: 1.5-2 L daily
• Increase salt intake: 6-10 g daily (unless contraindicated)
• Avoid triggers: Hot baths, prolonged standing, large meals, alcohol
• Graduated compression stockings: Thigh-high, 20-30 mmHg
• Physical counter-manoeuvres: Leg crossing, squatting, muscle tensing before standing
• Head-up tilt during sleep: 10-20° elevation (prevents nocturnal natriuresis)
• Slow position changes: Sit before standing, pause at edge of bed

Dietary Measures:

• Small frequent meals (reduce postprandial hypotension)
• Water bolus therapy: 500 mL water rapidly before standing

Medication Review

• Reduce or discontinue antihypertensives if possible
• Avoid or minimise diuretics
• Review all medications causing orthostatic hypotension

Pharmacological Treatment (If Refractory)

Fludrocortisone (mineralocorticoid):

• Dose: 0.1-0.2 mg daily
• Increases blood volume and vascular sensitivity
• Monitor: Hypokalaemia, supine hypertension, oedema

Midodrine (α1-agonist):

• Dose: 2.5-10 mg three times daily
• Vasoconstriction increases standing BP
• Avoid evening dose (supine hypertension)

---

4. Cardiac Interventions

Carotid Sinus Hypersensitivity

Prevalence: 30-40% of older adults with unexplained falls. [15]

Definition: Asystole > 3 seconds (cardioinhibitory) or BP drop > 50 mmHg (vasodepressor) with carotid sinus massage.

Management:

• Cardiac pacing for cardioinhibitory CSH reduces falls by 58% (SAFE PACE trial). [15]
• Dual-chamber pacing recommended
• Consider in unexplained recurrent falls with documented CSH

Arrhythmias

• Permanent AF: Rate control, anticoagulation (balance bleeding risk)
• Bradycardia/heart block: Permanent pacemaker
• Tachyarrhythmias: Appropriate pharmacological or ablative therapy

---

5. Vision Assessment and Intervention

Evidence

• Cataract surgery (first eye) reduces falls by 34% in women. [2]
• Multifocal glasses may increase fall risk during walking (especially stairs); consider single-lens distance glasses for outdoor mobility. [2]

Recommendations

• Annual vision assessment: Optometry review for all older adults
• Cataract surgery: If visual impairment present
• Update glasses prescription: Ensure current
• Treat eye disease: Glaucoma, macular degeneration
• Consider single-lens glasses: For outdoor walking, stairs

---

6. Home Hazard Assessment and Modification

Evidence

Home safety assessment and modification by occupational therapist reduces falls, particularly in high-risk individuals (history of falls). [2,3]

Key Home Modifications

Lighting:

• Bright, even lighting throughout home
• Night lights in bedroom, bathroom, hallways
• Light switches at top and bottom of stairs
• Reduce glare and shadows

Floor Surfaces:

• Remove loose rugs or secure with non-slip backing
• Remove clutter, electrical cords
• Non-slip mats in bathroom
• Repair uneven floors

Bathroom:

• Install grab bars near toilet and in shower/bath
• Raised toilet seat
• Non-slip bath mat or shower chair
• Ensure hot water temperature less than 49°C

Stairs:

• Secure handrails on both sides
• Ensure adequate lighting
• Mark edge of top and bottom steps with contrasting tape
• Remove clutter
• Repair loose carpets or treads

Bedroom:

• Bed at appropriate height (feet flat on floor when sitting)
• Clear path to bathroom
• Night light
• Phone and lamp within reach

Other:

• Telephone within easy reach
• Remove low furniture, footstools
• Secure rugs and carpets
• Pet management (prevent tripping)

Footwear:

• Avoid slippers, backless shoes
• Well-fitted supportive shoes with low heel and non-slip sole
• Avoid walking in socks

---

7. Vitamin D Supplementation

Evidence

• Cochrane review: Vitamin D supplementation reduces falls in those with low baseline vitamin D levels (less than 50 nmol/L). [16]
• Dose: 800-1000 IU daily (combined with calcium if dietary intake inadequate)
• May improve muscle strength and balance in deficient individuals
• Effect most pronounced in those with severe deficiency or history of falls

Recommendations

• Check 25-OH vitamin D levels in all older adults with falls
• Supplement if less than 50 nmol/L: Vitamin D 800-1000 IU daily
• Calcium: 1000-1200 mg daily (dietary + supplementation)

---

8. Bone Health and Osteoporosis Management

Rationale

• 95% of hip fractures caused by falls [7]
• Reducing fracture risk reduces fall-related morbidity and mortality

Assessment

• DEXA scan (bone mineral density) in all older adults with falls
• FRAX score: 10-year fracture risk assessment

Management

Lifestyle:

• Weight-bearing exercise
• Adequate calcium (1000-1200 mg/day) and vitamin D (800-1000 IU/day)
• Smoking cessation
• Moderate alcohol intake

Pharmacological (If Osteoporosis Diagnosed):

• First-line: Bisphosphonates (alendronate, risedronate)
• Alternatives: Denosumab, teriparatide, raloxifene
• Hip protectors: Some evidence for reducing hip fractures in high-risk individuals (e.g., nursing home residents), but compliance often poor [17]

---

9. Footwear and Podiatry

Assessment

• Foot examination: deformities, calluses, ulcers, nail problems
• Footwear assessment: inappropriate shoes increase fall risk

Interventions

• Podiatry referral: Foot care, orthoses for deformities
• Appropriate footwear: Well-fitted, supportive, low heel, non-slip sole, enclosed heel
• Avoid: Slippers, backless shoes, high heels, new shoes (until broken in)

---

10. Assistive Devices and Mobility Aids

Assessment

• Gait and balance impairment
• Current use of aids (correct type and use?)

Interventions

• Walking stick/cane: Single-point for mild imbalance
• Walking frame/rollator: Severe imbalance, bilateral support needed
• Physiotherapy assessment: Ensure correct sizing and technique
• Training in use: Improper use may increase fall risk

Note: Provision of walking aid alone without training does not reduce falls and may increase risk.

---

11. Education and Behavioral Strategies

Patient and Carer Education

• Falls are not inevitable with aging
• Multiple interventions reduce fall risk
• Importance of reporting falls
• How to get up from floor safely
• When to seek help

Fear of Falling

• Common (40-70% of fallers) and leads to activity restriction [8]
• Cognitive-behavioural therapy: Addresses fear and builds confidence
• Structured exercise programmes: Improve confidence and self-efficacy

---

12. Multidisciplinary Falls Clinic Referral

Indications for Specialist Falls Service

• Recurrent falls (≥2 in past year)
• Unexplained falls after initial assessment
• Complex multifactorial risk
• Syncopal falls requiring specialist investigation

Multidisciplinary Team

• Geriatrician
• Physiotherapist
• Occupational therapist
• Pharmacist
• Nurse specialist
• Cardiologist (if syncope/cardiac cause)

---

Special Populations

Dementia

Challenges:

• May not report falls or symptoms
• Impaired judgment increases risk-taking
• Wandering behaviour
• Medication side effects more pronounced

Management Considerations:

• History from carers essential
• Simplify medication regimens
• Increase supervision
• Environmental modifications critical
• Avoid physical restraints (increase agitation and fall risk)
• Balance safety with autonomy and quality of life

Nursing Home and Residential Care

Epidemiology:

• Fall rate: 1.5-3 falls per bed per year (50-75% of residents fall annually) [6]
• Higher injury rate than community-dwelling older adults

Evidence-Based Interventions:

• Supervised exercise programmes: 55% reduction in fall rate (Sunbeam Program) [6]
• Medication review and reduction
• Vitamin D and calcium supplementation
• Staff education
• Environmental modifications
• Hip protectors (mixed evidence, poor compliance)

Challenges:

• Frailty and multimorbidity
• Cognitive impairment
• High dependency levels
• Need to balance safety with resident autonomy

Parkinson's Disease

Specific Fall Risks:

• Postural instability and impaired righting reflexes
• Freezing of gait
• Dyskinesias
• Orthostatic hypotension (disease and medication-related)

Management:

• Optimise Parkinson's medications (balance motor control vs. orthostatic hypotension)
• Specialist physiotherapy (gait cueing strategies, movement strategies for freezing)
• Home modifications
• Consider referral to Parkinson's disease specialist

Anticoagulated Patients

Increased Risk:

• Higher risk of intracranial haemorrhage and serious bleeding with falls
• Risk-benefit assessment of anticoagulation

Management:

• CT head for any head trauma (even minor)
• Optimise fall-risk factors aggressively
• Consider alternative stroke prevention if very high fall risk (e.g., left atrial appendage occlusion in AF)
• Do not routinely discontinue anticoagulation solely due to fall risk (evidence suggests benefit often outweighs risk)

---

Prognosis and Outcomes

Natural History

• Recurrence: 50-60% of fallers will fall again within 1 year without intervention [1]
• Injury rate: 20-30% of falls result in moderate to severe injury [1,5]
• Hip fracture: 1-year mortality 20-30%; only 50% return to previous function [7]
• Functional decline: Falls often trigger spiral of decreased mobility, fear, further functional loss

Impact of Interventions

With Evidence-Based Multifactorial Interventions: [2,3,4]

• 23% reduction in fall rate (community-dwelling)
• 15% reduction in number of fallers
• Exercise most effective: 23% reduction in fall rate [4]
• Cardiac pacing for CSH: 58% reduction in falls [15]

Quality of Life:

• Interventions improve functional independence
• Reduce fear of falling
• Delay or prevent nursing home admission

• Safe home environment
• Adequate carer/social support
• Clear plan for follow-up and intervention
• Patient/carer understand red-flag symptoms

Discharge Planning and Follow-Up

Essential Components:

1. Injury-specific instructions

   • Wound care, analgesia
   • Red-flag symptoms (worsening headache, confusion, neurological deficit)

2. Falls prevention plan

   • Multifactorial assessment completed or arranged
   • Specific interventions initiated or referrals made

3. Medication review

   • Reduce or stop high-risk medications
   • Written medication plan

4. Referrals

   • Physiotherapy: Exercise programme, gait and balance training, mobility aid assessment
   • Occupational therapy: Home assessment and modifications
   • Falls clinic: Recurrent or unexplained falls
   • Optometry: Vision assessment
   • Podiatry: Foot problems
   • Cardiology: Syncope, arrhythmia, CSH
   • Bone health: DEXA scan, osteoporosis management

5. Primary care follow-up

   • Review within 1-2 weeks
   • Coordinate multifactorial interventions
   • Monitor response to interventions

6. Patient and carer education

   • Written information on fall prevention
   • How to get up from floor safely
   • When to seek help

7. Return precautions

   • Worsening headache, confusion, vomiting (head injury)
   • New weakness, numbness (stroke)
   • Syncope, palpitations, chest pain (cardiac)
   • Unable to mobilise, severe pain
   • Further falls

Key Clinical Pearls

Diagnostic Pearls

1. Falls are a symptom, not a diagnosis - always seek underlying cause(s)
2. Multifactorial in most cases - average of 4-5 risk factors per faller [9]
3. Orthostatic vital signs are mandatory - positive in 15-30% [11]
4. ECG for all unexplained falls - may reveal arrhythmia
5. CT head if anticoagulated - even with minor head trauma [14]
6. Consider UTI - atypical presentation in elderly
7. Don't forget "long lie" complications - CK, pressure injuries, hypothermia
8. Previous falls are strongest predictor of future falls
9. Medication review is essential - polypharmacy ≥4 drugs increases risk 1.5-fold [10]
10. Syncope requires full workup - cardiac cause until proven otherwise

Treatment Pearls

1. Exercise is most effective intervention - 23% fall reduction [4]
2. Multifactorial assessment + targeted interventions - 23% reduction [2,3]
3. Tai Chi works - evidence-based for balance and fall prevention [4]
4. Stop the benzodiazepines - strong evidence for deprescribing [10]
5. Vitamin D if deficient - 800-1000 IU daily [16]
6. Cardiac pacing for cardioinhibitory CSH - 58% fall reduction [15]
7. Home assessment works - especially if history of falls [2]
8. Limit opioids - increased fall risk and sedation
9. Address fear of falling - present in 40-70% and causes activity restriction [8]
10. Combination of balance + strength training most effective exercise [4]

Disposition Pearls

1. Low threshold for admission if anticoagulated with head trauma
2. Safe discharge requires safe environment - assess before discharge
3. Physiotherapy referral is intervention, not optional - essential component
4. Ensure follow-up arranged - primary care within 1-2 weeks
5. Written fall prevention plan - patient and carer education
6. Multidisciplinary approach - no single intervention adequate
7. Document baseline function - for future comparison
8. Recurrent falls need specialist input - falls clinic referral
