Understanding the Basics of a Fall Risk Score
A fall risk score is a quantified result from a standardized clinical assessment. Rather than being a single, universal number, it is the outcome of a specific tool, like the Morse Fall Scale or the Hendrich II Fall Risk Model. These scores help healthcare providers categorize individuals into low, moderate, or high-risk groups, allowing them to implement targeted, effective prevention strategies.
Why Fall Risk Assessment is Crucial for Seniors
Falls are not an inevitable part of aging. While an aging body may experience changes that increase fall risk, many falls are preventable. Assessing this risk offers several key benefits:
- Prevents Injuries: Proactively identifying risk factors can prevent serious injuries, such as hip fractures or head trauma.
- Personalized Care: The score guides the creation of a tailored care plan, including physical therapy, home modifications, or medication adjustments.
- Maintains Independence: By improving balance and reducing fall anxiety, a person can remain more active and confident in their daily life.
- Early Health Detection: Assessments can uncover underlying health issues, such as vision problems or neuropathy, that contribute to falls.
Common Fall Risk Assessment Tools
There are several validated tools used by healthcare professionals to determine an individual's fall risk. Each uses a different set of criteria and scoring system.
Morse Fall Scale (MFS)
The MFS is one of the most widely used tools, particularly in hospital and long-term care settings. It assigns a numerical score based on six variables:
- History of falling: (Yes = 25, No = 0)
- Secondary diagnosis: (Yes = 15, No = 0)
- Ambulatory aid: (None/Bed rest = 0, Crutches/cane/walker = 15, Furniture = 30)
- IV/Heparin Lock: (Yes = 20, No = 0)
- Gait: (Normal/immobile = 0, Weak = 10, Impaired = 20)
- Mental Status: (Oriented to own ability = 0, Forgets limitations = 15)
The total score is then used to determine the risk level:
- 0–24: Low Risk
- 25–45: Moderate Risk
- >45: High Risk
Hendrich II Fall Risk Model
This model screens for eight independent risk factors and is often used in acute care. It assesses:
- Confusion, Disorientation, Impulsivity
- Symptomatic Depression
- Altered Elimination
- Dizziness/Vertigo
- Gender (Male)
- Administering Antiepileptics
- Administering Benzodiazepines
- Up and Go Test (Get-Up-and-Go)
A total score of 5 or greater indicates a high risk for falls.
The Timed Up and Go (TUG) Test
Less of a scoring system and more of a performance-based test, the TUG measures mobility and balance. The individual is timed as they stand from a chair, walk 10 feet, turn around, and sit back down. A longer time indicates a higher fall risk.
Fall Risk Factors: What Increases Your Score?
A high fall risk score is not an indictment but a signal to take preventive action. The factors that contribute to a higher score are often modifiable and manageable.
Medical and Physical Factors
- History of Previous Falls: A history of falling once significantly increases the risk of falling again.
- Medications: Certain medications, including sedatives, antidepressants, and blood pressure drugs, can cause dizziness, drowsiness, or affect balance. Polypharmacy (taking four or more medications) is a notable risk factor.
- Gait and Balance Issues: Muscle weakness, impaired gait, or balance difficulties directly impact stability.
- Chronic Conditions: Diseases like arthritis, diabetes, and Parkinson's can affect strength, sensation, and coordination.
- Vision and Sensation: Poor eyesight, reduced sensation in the feet, and other sensory impairments are significant contributors.
Environmental Factors
- Home Hazards: Clutter, loose rugs, poor lighting, and a lack of grab bars in bathrooms are common environmental dangers.
- Inappropriate Footwear: Shoes with poor support, slick soles, or those that are ill-fitting can increase instability.
Interventions Based on Your Score
Once a fall risk score is determined, a healthcare team can recommend a multi-faceted intervention plan tailored to the individual's needs.
- Exercise Programs: Regular exercise that focuses on strength, balance, and flexibility (like Tai Chi or the Otago Exercise Program) can significantly reduce fall rates.
- Medication Management: A doctor or pharmacist can review medications to reduce or eliminate those with side effects that increase fall risk.
- Home Safety Modifications: An occupational therapist can perform a home assessment and recommend installing grab bars, improving lighting, and removing trip hazards.
- Assistive Devices: For those with moderate to high risk, using a cane, walker, or other assistive device can provide crucial stability.
Comparing Fall Risk Assessment Tools
| Feature | Morse Fall Scale (MFS) | Hendrich II Fall Risk Model | Timed Up and Go (TUG) | CDC STEADI Algorithm |
|---|---|---|---|---|
| Primary Use | Hospital and long-term care settings | Acute care settings (hospital) | Community and clinical settings | Comprehensive clinical program |
| Assessment Type | Checklist of six categories | Checklist of eight risk factors + 'Up and Go' | Performance-based test | Screening, assessment, and intervention |
| Risk Factor Focus | History of falls, diagnosis, ambulatory aid, IV, gait, mental status | Confusion, depression, elimination, vertigo, gender, meds, 'Up and Go' | Gait speed, balance, mobility | History of falls, medications, balance, home hazards, vision |
| Scoring | Numerical score from 0–125 | Numerical score, score of ≥5 is high risk | Time in seconds; longer time = higher risk | Yes/No screening questions leading to assessment tools |
| Target Audience | Clinicians, especially nurses | Clinicians | Therapists, clinicians | General practitioners, care teams |
Taking Control of Your Fall Risk
Receiving a fall risk score is not a final verdict but the beginning of a proactive journey toward greater safety and confidence. Discussing your health history, concerns, and lifestyle with a healthcare provider is the first and most important step. They can help you determine the most appropriate assessment tool and, crucially, develop a personalized plan of action.
Remember that small, consistent changes can make a big difference. Improving your balance, reviewing your medications, and making simple changes to your home environment can all contribute to a safer, healthier future.

Conclusion
In summary, a fall risk score provides a structured, evidence-based method for evaluating a person's likelihood of falling. By leveraging tools like the Morse Fall Scale or the Hendrich II model, healthcare providers can identify specific risk factors and design targeted interventions. For individuals, understanding your score empowers you to take control of your health and actively engage in strategies, from exercise and medication management to home modifications, that dramatically reduce your risk of falls and help ensure a safer, more independent future. Taking the time for a proper fall risk assessment is a foundational step in healthy aging.
