Fall Prevention Guidelines

Risk Factors and Assessment

• The American Geriatrics Society recommends that a visual tool for fall prevention education should prominently display the ranked fall risk factors with their relative risk ratios, including muscle weakness (RR 4.4), history of falls (RR 3.0), gait deficit (RR 2.9), balance deficit (RR 2.9), use of assistive device (RR 2.6), visual deficit (RR 2.5), arthritis (RR 2.4), impaired ADL (RR 2.3), depression (RR 2.2), and cognitive impairment (RR 1.8) 1
• The risk of falling increases dramatically as the number of risk factors accumulates, emphasizing the need for a multifactorial risk assessment framework 1, 2

Medication Risk and Management

• The American Geriatrics Society suggests highlighting high-risk medications with their odds ratios, including psychotropic medications (OR 1.7), class 1a antiarrhythmics (OR 1.6), digoxin (OR 1.2), and diuretics (OR 1.1), as well as emphasizing the polypharmacy threshold of taking ≥4 medications, which significantly increases risk 1, 3

Exercise and Physical Therapy

• Exercise interventions, including balance and functional exercises, gait training protocols, and strength training focusing on lower extremities, have been shown to reduce fall risk by 23% (RR 0.77, 95% CI 0.71-0.83) 1

Environmental Modification

• The American Geriatrics Society recommends including a home hazard assessment checklist, which should identify potential hazards such as poor lighting, loose carpets, and lack of bathroom safety equipment, and emphasize that environmental modification alone without other interventions is not beneficial 1, 2, 3

Special Populations Considerations

• For patients with osteoporosis, arthritis, or neurological conditions, the tool should include hip protector recommendations, bone strengthening medication information, and arthritis-specific risk quantification (RR 2.4) 1, 3, 4

Assessment Tools

• The American College of Physicians recommends using the Timed Get-Up-and-Go test and the Functional Reach Test as feasible primary care screening tools for fall risk assessment 5, 6

Multifactorial Intervention

• A multifactorial assessment and intervention approach, including comprehensive assessment, referral pathways, and follow-up reassessment protocols, can reduce fall risk by 11% (pooled RR 0.89) 5, 7

Approach to Geriatric Falls

Initial Assessment

• The American College of Emergency Physicians recommends beginning every fall evaluation by asking if a healthy 20-year-old would have fallen in the same situation, and if the answer is "no," a comprehensive multifactorial assessment is mandatory 8, 9

Risk Factor Identification

• The American Geriatrics Society recommends systematically evaluating modifiable factors using the P-SCHEME mnemonic, including suboptimal footwear 10, cognitive impairment 11, hypotension 10, eyesight 10, medications 10, and environmental factors [12] [13]

Medication Review

• The Journal of the American Geriatrics Society recommends reviewing and modifying medications, especially psychotropic drugs, as this is a Class B recommendation with consistent evidence of benefit 14, 12
• The American Geriatrics Society recommends reducing total medication count if ≥4 medications, as polypharmacy independently increases fall risk 11

Multifactorial Interventions

• The Journal of the American Geriatrics Society recommends implementing evidence-based interventions for community-dwelling older adults, including gait training and assistive device prescription 11, exercise programs with balance training 14, medication review and modification 11, treatment of postural hypotension 14, and environmental hazard modification 12
• The American Geriatrics Society recommends vitamin D supplementation of ≥800 IU daily for those with deficiency or at increased fall risk 10, 11

Disposition and Follow-Up

• The American College of Emergency Physicians recommends considering admission if patient safety cannot be ensured, and arranging expedited outpatient follow-up within 1-2 weeks, including home safety assessment 8, 9, 10
• The American Geriatrics Society recommends that all patients admitted after a fall must be evaluated by physical therapy and occupational therapy, and have a multidisciplinary team review for medication optimization 11, 9

Ongoing Management

• The American Geriatrics Society recommends ordering a DEXA scan to assess fracture risk in high-risk patients, depression screening using PHQ-2, cognitive screening if not already performed, annual fall risk reassessment, and monitoring for recurrence of falls 10, 11

Fall Risk Assessment and Management

Introduction to Fall Risk Factors

• The American College of Emergency Physicians explicitly lists "loss of consciousness/altered mental status" as just one of 14 key historical elements, while "falls in the previous [time period]" is prioritized as a separate critical factor, indicating that fall history signals underlying multifactorial deficits that have already manifested clinically 15, 16
• Fall history consistently ranks as one of the top three independent predictors across all clinical settings, with a relative risk of 3.0, making it the single strongest predictor of in-hospital falls 15, 16

Clinical Assessment and Risk Stratification

• Patients with prior falls have already demonstrated vulnerability through actual events, not just theoretical risk factors, and should be automatically considered high-risk regardless of mental status 15, 16
• The American College of Emergency Physicians recommends asking: "How many falls have you had in the previous 6 months?" to screen for fall history, and if ≥1 fall, the patient is automatically high-risk regardless of mental status 17
• The Mini-Cog can be used for rapid cognitive screening (<5 minutes) to evaluate mental status, but cognitive impairment contributes to risk but is not the primary driver in patients with fall history 17

Management of High-Risk Patients

• Implement multifactorial interventions immediately (Class B recommendation with consistent evidence) for patients with fall history, including physical therapy evaluation for gait training and assistive device prescription, medication review with focus on deprescribing psychotropics and reducing polypharmacy, and environmental modifications (handrails, adequate lighting, non-slip surfaces) 15, 16
• Assess and treat postural hypotension with orthostatic vital signs for patients with fall history, as it is a contributing factor to fall risk 15, 16
• Screen for reversible causes of delirium (infection, medications, metabolic derangements) and implement delirium prevention protocols (reorientation, sleep hygiene, early mobilization) for patients with altered mental status 16

Morbidity and Mortality Implications

• Falls are the leading cause of injury-related death among adults aged ≥65, and approximately 5% of older people who fall require hospitalization, with 10-25% resulting in fracture, laceration, or need for hospital care 16
• The combination of fall history plus altered mental status creates compounding risk, but fall history remains the dominant factor, with a relative risk 67% higher (3.0 vs 1.8) 16
