Understanding the Purpose of Fall Risk Assessments
While many people believe falls are an inevitable part of aging, they are often preventable. Fall risk assessments are standardized evaluations designed to identify an individual's specific risk factors for falling, allowing healthcare providers and caregivers to implement targeted interventions. This proactive approach is crucial for promoting safety, maintaining independence, and preventing the serious injuries that can result from falls, such as fractures or head trauma. Assessments can take place in various settings, from a doctor's office and hospital to a patient's own home, with the goal of identifying weaknesses, balance issues, and environmental hazards before an accident occurs.
Common Names for Fall Risk Assessment Tools
There is no single universal test for fall risk, but rather a toolbox of validated assessments used depending on the patient's condition and the clinical setting. These tools often focus on different aspects of mobility, strength, and cognitive function.
The Morse Fall Scale (MFS)
This is one of the most widely used fall risk assessment tools, particularly in acute care and hospital settings. The MFS is quick and simple to administer, scoring six variables to determine a patient's risk level. The factors include:
- History of falling
- Presence of a secondary diagnosis
- Use of ambulatory aids
- Intravenous (IV) therapy
- Gait
- Mental status
Scores are tallied to classify patients into low, medium, or high-risk categories, guiding staff on the level of fall prevention interventions needed.
The Timed Up and Go (TUG) Test
The TUG test is a simple and quick assessment of an individual's functional mobility and balance. The patient is timed as they rise from a chair, walk 10 feet, turn around, walk back to the chair, and sit down. A longer completion time, often 12 seconds or more for community-dwelling older adults, indicates a higher risk of falling. It provides valuable insight into gait, balance, and overall stability.
The Berg Balance Scale (BBS)
Unlike the TUG, the BBS is a more detailed assessment that measures an individual's static and dynamic balance through 14 different tasks. These tasks include standing unaided, transferring between chairs, and reaching forward while standing. Each task is scored, with a maximum total score of 56. A lower score indicates greater fall risk. The BBS takes more time but provides a more granular look at a person's balance abilities.
The Hendrich II Fall Risk Model
Specifically designed for the acute care setting, the Hendrich II model is another validated tool for identifying fall risk. It is notable for its inclusion of 'risky' medication categories as a key factor. Other variables considered include:
- Confusion/disorientation
- Depression
- Dizziness/vertigo
- Gender
- Symptomatic hypotension
- Use of anticonvulsants
CDC's STEADI Initiative
The Centers for Disease Control and Prevention (CDC) promotes a comprehensive approach to fall prevention called STEADI (Stopping Elderly Accidents, Deaths & Injuries). This initiative includes an initial screening tool with three key questions:
- Have you fallen in the past year?
- Do you feel unsteady when standing or walking?
- Do you worry about falling?
A positive answer to any of these questions triggers a more comprehensive assessment. Additional clinical tests like the 30-Second Chair Stand and the Four Stage Balance Test are also part of the STEADI protocol.
Putting an Assessment into Action
Conducting a fall risk assessment is only the first step. The true value lies in using the results to create a personalized, multi-component intervention plan. This may involve a combination of strategies tailored to the individual's specific risk factors.
Common interventions based on assessment results:
- Physical Therapy: Exercises to improve strength, balance, and gait.
- Medication Review: Optimizing or adjusting medications that cause drowsiness, dizziness, or confusion.
- Home Modifications: Installing grab bars, improving lighting, removing trip hazards like loose rugs.
- Assistive Devices: Recommending and training on the proper use of canes or walkers.
- Vision Check: Correcting vision issues that impair depth perception.
- Patient Education: Discussing risk factors and prevention strategies with the individual and their family.
For more detailed, evidence-based guidance on fall prevention strategies, a valuable resource is the Centers for Disease Control and Prevention's STEADI initiative, which provides a wealth of tools and information for both healthcare providers and the public.
Comparison of Common Fall Risk Assessment Tools
| Feature | Morse Fall Scale (MFS) | Timed Up and Go (TUG) | Berg Balance Scale (BBS) |
|---|---|---|---|
| Primary Setting | Acute care, hospital | Community, clinic | Clinic, therapy setting |
| Primary Focus | General risk factors | Functional mobility, gait | Static & dynamic balance |
| Equipment Needed | Assessment form | Stopwatch, chair, tape measure | Stopwatch, chair, various props |
| Time Required | Quick (typically <3 min) | Very quick | Longer (15-20 min) |
| Key Outcome | Risk score (low, med, high) | Time taken to complete | Total score out of 56 |
Conclusion: A Proactive Approach to Safety
Understanding what is the fall risk assessment called is an important step towards better senior care. By recognizing that different assessments exist for different purposes, individuals and caregivers can have more informed conversations with healthcare providers. The use of validated tools allows for a systematic and objective evaluation of risk, replacing guesswork with data-driven action plans. Ultimately, this approach empowers older adults to take control of their health, minimize risks, and enjoy greater independence and safety as they age.
