Which assessment tool should be used to identify risk for falls in the older adult?

Falls are a leading cause of injury-related deaths and emergency department visits for people aged 65 and older. To combat this, healthcare providers must understand which assessment tool should be used to identify risk for falls in the older adult, as the most effective tool depends on the setting and the patient's mobility level. A comprehensive approach often involves multiple tools to build a full clinical picture.

Quick Summary

This guide outlines the most effective, evidence-based tools for assessing fall risk in older adults. It compares instruments like the Timed Up and Go (TUG), Berg Balance Scale (BBS), and STEADI toolkit, detailing how to choose the right assessment based on patient factors and clinical setting. It also includes information on implementation and interpretation of results.

Key Points

• CDC's STEADI Toolkit: Use the STEADI program for a comprehensive, three-step approach involving screening, assessing, and intervening, ideal for primary care settings.

• Timed Up and Go (TUG) Test: The TUG is a quick and reliable measure of functional mobility; a time of 12 seconds or more suggests increased fall risk in community-dwelling adults.

• Berg Balance Scale (BBS): The BBS offers a more detailed, 14-item assessment of static and dynamic balance, making it useful in outpatient or physical therapy settings for guiding interventions.

• Morse Fall Scale (MFS): In acute care or inpatient settings, the MFS provides a rapid, efficient way to score fall risk based on patient factors, informing immediate care plans.

• Combine Clinical Judgment with Tools: No single tool is perfect; the best practice is to use validated tools in conjunction with expert clinical judgment and patient-specific risk factors.

• Choose Based on Setting: Select the appropriate tool for the setting—community, outpatient, or inpatient—to ensure the assessment is efficient and relevant to the patient's care plan.

• Actionable Interventions: The ultimate purpose of a fall risk assessment is to inform and implement effective, multifactorial interventions, such as exercise, medication review, and home safety modifications.

Understanding the Goals of Fall Risk Assessment

Identifying fall risk in older adults is a crucial step in fall prevention, which significantly improves quality of life and reduces healthcare costs. There is no single universal tool for all situations. Instead, clinicians must select a tool based on the specific clinical context, such as the patient's physical and cognitive status, the clinical setting (hospital vs. community), and the required depth of the assessment. An effective assessment should lead to actionable interventions, from exercise programs to home modifications.

Multi-step screening and assessment with CDC's STEADI

The Centers for Disease Control and Prevention (CDC) provides the evidence-based Stopping Elderly Accidents, Deaths, and Injuries (STEADI) toolkit. This is not a single test but a comprehensive, three-part program involving screening, assessing, and intervening. It's an excellent framework for primary care providers.

• Screen: The initial step is a simple screening, where a healthcare provider asks the patient three key questions about falls and balance issues. If the patient answers yes, a full assessment is triggered.
• Assess: The STEADI assessment includes several validated tests to measure gait, strength, and balance, including the Timed Up and Go (TUG) test, the 30-Second Chair Stand Test, and the 4-Stage Balance Test.
• Intervene: Based on the assessment results, the provider develops a personalized intervention plan, which might include exercise, medication review, and home safety modifications.

Functional mobility tests for dynamic balance

For a more focused evaluation of functional mobility, several performance-based tests are widely used and recommended.

• Timed Up and Go (TUG) Test: This is one of the most common and accessible tools. The patient stands up from a chair, walks 3 meters, turns, walks back, and sits down. A time of 12 seconds or more suggests a higher risk of falling in community-dwelling older adults. It has high inter-rater reliability but mixed predictive value for future falls in some populations.
• Berg Balance Scale (BBS): This 14-item scale is more comprehensive than the TUG, assessing static and dynamic balance through tasks like standing on one foot, transferring, and reaching forward. While it has excellent reliability and can predict some aspects of function, its ability to predict falls is less clear, especially in post-stroke populations where it showed less predictive value than expected.

Setting-specific assessment tools

Inpatient settings require different tools for rapid assessment and constant monitoring. Here, clinical judgment and established scales are key.

• Morse Fall Scale (MFS): Widely used in hospitals, the MFS is a scoring system based on six factors: history of falls, secondary diagnosis, use of ambulatory aids, IV access, gait, and mental status. Its predictive accuracy varies but is a standard in acute care settings. A recent study found it to have high predictive value in older adult inpatients when combined with the Barthel Index.
• Hendrich II Fall Risk Model: This tool incorporates eight risk factors, including confusion/disorientation, depression, dizziness, gender, and medication use. Studies suggest it may be more sensitive and specific than the MFS for predicting falls in acute care inpatients.

Choosing the Right Assessment Tool

Selecting the best tool depends on the setting and the patient's individual needs. For a basic, low-cost screening in a community or primary care setting, the CDC's STEADI screen is an excellent starting point. For a more detailed, functional assessment of balance in a physical therapy context, the BBS is useful but may require more time. The TUG test offers a quick, reliable snapshot of mobility. In an inpatient hospital setting, scales like the MFS and Hendrich II are designed to provide rapid risk stratification. The best practice often involves a multi-pronged approach, using a combination of screening, performance-based tests, and clinical judgment.

Conclusion: Choosing a Comprehensive Strategy

The ideal approach for identifying fall risk in older adults is not to rely on a single assessment tool but to employ a targeted strategy based on the patient's environment and health status. In primary care, a systematic approach like the CDC's STEADI toolkit provides a structured, evidence-based pathway from screening to intervention. For a quick check of mobility, the Timed Up and Go (TUG) test is efficient and reliable. In rehabilitation or outpatient settings, the Berg Balance Scale (BBS) offers a more detailed assessment of balance capabilities. In acute care, the Morse Fall Scale (MFS) or Hendrich II model provides a rapid, data-driven risk score. The strongest fall prevention programs combine these assessments with personalized, multifactorial interventions addressing medication management, exercise, and home safety. Ultimately, the goal is to use the right tool to inform a proactive strategy, helping older adults maintain independence and reduce fall-related injuries.

Frequently Asked Questions

What is the most effective tool for community-dwelling older adults?

For community-dwelling older adults, the CDC's STEADI (Stopping Elderly Accidents, Deaths, and Injuries) toolkit is highly effective. It combines a simple screening questionnaire with functional assessment tests like the Timed Up and Go (TUG) to inform personalized interventions.

How reliable is the Timed Up and Go (TUG) test?

The TUG test has demonstrated excellent inter-rater and intra-rater reliability, meaning different testers or the same tester can achieve consistent results. However, its predictive ability for future falls, when used alone, can be mixed depending on the patient population.

Which tool is best for hospital inpatients?

In an acute care hospital setting, the Morse Fall Scale (MFS) is a widely used and efficient tool for rapid risk assessment. Studies also suggest that the Hendrich II Fall Risk Model may offer higher sensitivity in some inpatient settings.

What is the difference between the Morse Fall Scale and the Hendrich II Fall Risk Model?

The Morse Fall Scale assesses a patient's history of falls, diagnosis, ambulatory aids, IV access, gait, and mental status. The Hendrich II model includes different risk factors like mental/emotional status, dizziness, gender, and medications. Some research suggests the Hendrich II may be more sensitive in acute care.

Is the Berg Balance Scale good for predicting falls?

While the Berg Balance Scale (BBS) is excellent for assessing a patient's balance capabilities, some systematic reviews have found insufficient evidence to recommend it as a strong predictor of fall risk, especially in the post-stroke population.

What should be included in a multifactorial fall risk assessment?

According to the AGS/BGS clinical guideline, a multifactorial assessment includes a focused history (fall history, medications), a physical exam (gait, balance, strength), a functional assessment (activities of daily living), and an environmental assessment (home safety).

Should fall risk assessments be conducted routinely?

Yes, fall risk assessments should be conducted routinely, particularly during annual physicals or after any significant change in a patient's health, medication, or mobility.
