Fall Prevention Strategies for Older Adults
Multifactorial interventions that include exercise focusing on balance and strength training, medication review, and home safety assessment are the most effective strategies for preventing falls in older adults. 1
Screening and Assessment
All older adults should be screened annually for fall risk using three key questions:
- Have you fallen in the past year?
- Do you feel unsteady when standing or walking?
- Are you worried about falling? 1
For those who report a single fall, perform the "Get Up and Go Test" to assess mobility and balance 1
Comprehensive assessment is needed for those who:
- Present with falls
- Report recurrent falls
- Show gait or balance abnormalities 1
Evidence-Based Prevention Strategies
1. Exercise Interventions
- Most effective component: Balance and functional exercises reduce falls by 23% (655 falls per 1000 patient-years vs 850 falls in control groups) 2
- Recommended frequency: 3 sessions per week for at least 12 months 1
- Exercise program should include:
- Balance training
- Strength/resistance training
- Gait training
- 50-60 minutes of exercise daily 1
- Tai Chi is a promising balance exercise, though requires further evaluation 3
2. Medication Review and Modification
- Review and modify medications, particularly:
- Special attention to those taking four or more medications 3
- Medication reduction was a prominent component of effective fall-reducing interventions in multiple studies 3
3. Home Safety Assessment and Environmental Modification
- Home safety assessment and modifications should include:
- Removing tripping hazards
- Installing handrails and grab bars
- Improving lighting
- Ensuring even floor surfaces 1
- A facilitated environmental home assessment should be considered when older patients at increased risk are discharged from hospital 3
- Environmental modifications reduced falls by 26% in high-risk individuals 4
4. Management of Medical Conditions
- Address and treat:
Special Considerations
For High-Risk Individuals
- Active multifactorial interventions reduced fall rates by 36% compared to usual care 5
- Components that showed significant reduction in falls:
- Exercise (34% reduction)
- Environmental modification (35% reduction) 5
- Consider external hip protectors to prevent fractures 1
For Hospital Settings
- Patient and staff education programs significantly reduce hospital falls (30% reduction in fall rates) 6
- Chair alarms, bed alarms, and wearable sensors were not associated with significant fall reductions 6
For Community-Based Programs
- Community-wide initiatives should include:
Implementation Algorithm
- Screen all older adults annually for fall risk
- For those at risk:
- Perform comprehensive assessment including medication review, gait/balance evaluation, vision check, and postural blood pressure
- Implement targeted interventions:
- First: Structured exercise program focusing on balance and strength
- Second: Medication review and modification, especially psychotropics
- Third: Home safety assessment and environmental modifications
- Fourth: Treatment of medical conditions (vision, cardiovascular, etc.)
- Follow-up and reassessment:
- Reassess fall risk at all transition points and whenever there is a change in health status
- Monitor progress and adjust interventions as needed 1
Common Pitfalls to Avoid
- Relying solely on fall risk assessment tools without implementing interventions 6
- Focusing on single interventions rather than multifactorial approaches 3
- Neglecting medication review, particularly psychotropic medications 3
- Providing advice alone without measures to implement recommended changes 3
- Failing to address environmental hazards in the home 1
- Overlooking the importance of sustained compliance with interventions 3
The evidence clearly shows that multifactorial interventions are more effective than single interventions, with exercise being the most consistently beneficial component across studies 3, 1, 2.
