Understanding the Purpose of Fall Risk Assessment
Fall risk assessment is a systematic process used by clinicians to identify individuals at a higher risk of experiencing a fall. The results of these assessments are crucial for developing personalized care plans aimed at preventing falls and mitigating potential injuries. Scales of fall risk assessment are not just a one-time checklist; they are dynamic tools used on admission, after a fall, upon a change in condition, and during transfers to new care settings. The process involves evaluating a patient's medical history, physical condition, cognitive status, and other factors to quantify their risk level.
The Most Common Fall Risk Assessment Scales
Several different fall risk assessment scales exist, each with its own focus and scoring methodology. The choice of scale often depends on the specific healthcare setting and patient population. Some of the most widely used and validated tools include the Morse Fall Scale, the Hendrich II Fall Risk Model, and the Timed Up and Go (TUG) Test. Understanding the distinctions between these tools is key to appreciating the depth of a comprehensive fall prevention strategy.
Morse Fall Scale (MFS)
The Morse Fall Scale (MFS) is a rapid and straightforward tool used frequently in acute care and long-term care facilities. It evaluates six variables to generate a total score, ranging from 0 to 125, which correlates with a patient's fall risk level.
-
Variables Scored:
- History of Falling (25 points): A recent fall history indicates a higher risk of future falls.
- Secondary Diagnosis (15 points): Having an additional medical condition beyond the primary one can increase risk.
- Ambulatory Aid (0, 15, or 30 points): Points are assigned based on whether a patient is bedridden, uses a cane/walker, or relies on furniture for support.
- IV Therapy/Heparin Lock (20 points): The presence of an IV can interfere with movement and coordination.
- Gait (0, 10, or 20 points): Normal, weak, or impaired gait contributes to the score.
- Mental Status (0 or 15 points): Awareness of limitations can reduce risk, while forgetting or overestimating abilities increases it.
-
Score Interpretation:
- 0–24: Low Risk
- 25–45: Medium Risk
- Above 45: High Risk
Hendrich II Fall Risk Model
The Hendrich II Fall Risk Model is another popular tool, often used in long-term care and hospital settings. Unlike the MFS, it focuses on eight independent risk factors, plus the 'Get Up and Go' test. A total score of 5 or greater indicates a high risk for falls.
- Risk Factors Assessed:
- Confusion/Disorientation
- Depression
- Altered Elimination
- Dizziness/Vertigo
- Gender (Male)
- Antiepileptic Medication
- Benzodiazepine Medication
- 'Get Up and Go' Test result
Timed Up and Go (TUG) Test
The TUG test is a simple, quick-to-administer assessment often used in non-acute settings like outpatient physical therapy. It measures a person's mobility, gait, and balance by timing how long it takes them to rise from a chair, walk 10 feet, turn around, walk back, and sit down. Performance under 10 seconds is generally considered normal, while longer times suggest a higher fall risk.
Berg Balance Scale
The Berg Balance Scale (BBS) is a more detailed, 14-item assessment that measures both static and dynamic balance. The patient completes various tasks, such as standing on one foot or reaching forward, and their performance is scored. The total score, out of a maximum of 56, provides a more granular assessment of balance, with lower scores indicating higher fall risk.
How Assessment Results Guide Fall Prevention
The results from these scales are not just numbers; they directly inform the interventions put in place to prevent falls. A low-risk score might lead to standard prevention protocols, while a high-risk score necessitates a more intensive, personalized approach.
- Low-Risk Interventions: Basic measures like ensuring the patient has non-skid footwear, placing the call bell within reach, and keeping the bed in a low position are standard practice.
- High-Risk Interventions: For high-risk individuals, strategies might include bed alarms, specialized gait training with a physical therapist, increased supervision, and medication review to identify any sedatives or other drugs that could increase unsteadiness.
Comparison of Fall Risk Assessment Tools
| Assessment Scale | Primary Use | Assesses | Administration Time | Score Interpretation | Key Focus |
|---|---|---|---|---|---|
| Morse Fall Scale (MFS) | Hospitals, Long-term Care | History of falls, diagnosis, ambulatory aid, IV, gait, mental status | Quick (under 3 min) | 0-125, ranges for Low/Med/High Risk | Identifies risk factors to guide intervention |
| Hendrich II Fall Risk Model | Long-term Care, Hospitals | 'Get Up and Go' test, confusion, depression, medications, elimination | Moderate | ≥5 indicates High Risk | Combination of specific risk factors and mobility |
| Timed Up and Go (TUG) | Community, Clinics | Mobility, gait, balance | Very quick | Time-based threshold (e.g., >10-14 seconds = high risk) | Quick functional mobility screen |
| Berg Balance Scale (BBS) | Community, Rehabilitation | Static and dynamic balance | Longer (10-15 min) | 0-56, lower score = higher risk | Detailed assessment of balance performance |
The Evolution of Fall Risk Assessment
Over time, fall risk assessment has evolved beyond simple scales. The current approach emphasizes a multi-faceted strategy that combines quantitative data from assessment tools with qualitative observations and a deep understanding of the patient's individual circumstances. This includes considering environmental factors, such as clutter in the home, poor lighting, and slippery rugs. Comprehensive fall prevention programs, such as the STEADI initiative from the CDC, provide healthcare providers with a systematic, evidence-based approach to assessing and managing falls, both in clinical settings and after a patient's discharge. For more details on this comprehensive approach, refer to the CDC STEADI toolkit.
Conclusion: A Proactive Approach to Safety
In conclusion, a scale of fall risk assessment is an indispensable tool in healthy aging and senior care. Scales like the Morse Fall Scale, Hendrich II, and TUG provide structured frameworks for healthcare professionals to evaluate a patient's risk profile. However, these tools are most effective when integrated into a larger, comprehensive fall prevention strategy that addresses the full spectrum of risk factors, from physical deficits to environmental hazards. By actively using these scales and implementing targeted interventions, caregivers and healthcare providers can significantly reduce the incidence of falls, helping seniors maintain their independence, mobility, and overall quality of life.
