STEADI CDC Algorithm: Fall Risk Screening & Prevention Guide
In short
The CDC STEADI algorithm operationalizes geriatric fall prevention through 3 core screening questions, objective physical testing, and targeted multi-factorial risk reduction.

The STEADI Framework: Turning Reactive Fall Care into Proactive Prevention
Developed by the U.S. Centers for Disease Control and Prevention (CDC), the STEADI (Stopping Elderly Accidents, Deaths, & Injuries) clinical initiative provides healthcare professionals with an actionable, evidence-based algorithm to screen, assess, and intervene before a catastrophic fall occurs.
Falls are not an inevitable part of aging. Most falls are caused by the interaction of multiple modifiable risk factors: muscle weakness, gait instability, psychoactive medications, orthostatic hypotension, visual deficits, and domestic hazards. STEADI stratifies older adults into Low, Moderate, and High fall-risk categories, dictating targeted clinical care pathways.
The Three Key Screening Questions and Core Physical Tests
| Assessment Component | Clinical Administration / Question | Positive High-Risk Finding | Immediate Clinical Referral / Action | |
|---|---|---|---|---|
| Screening Question 1 | Have you fallen in the past year? | Yes (>= 1 fall with injury, or >= 2 falls without injury) | Triggers immediate High-Risk evaluation pathway | |
| Screening Question 2 | Do you feel unsteady when standing or walking? | Yes | Triggers thorough objective mobility testing | |
| Screening Question 3 | Do you worry about falling? | Yes | Indicates high fear of falling and potential activity restriction | |
| Core Test 1: Mobility | Timed Up and Go (TUG) Test (walk 3 metres, turn, return) | Time >= 12 seconds | Prescribe gait aids and physiotherapy balance retraining | |
| Core Test 2: Strength | 30-Second Chair Stand Test (full stands without arms) | Score below age/gender norms (typically < 10-12 stands) | Prescribe progressive lower extremity resistance training | |
| Core Test 3: Balance | 4-Stage Balance Test (parallel, semi-tandem, tandem, single leg) | Cannot hold tandem stance for 10 seconds | High fall risk; refer for intensive vestibular/sensory balance therapy |
STEADI Risk Stratification and Clinical Action Pathways
- Low-Risk Pathway (0 falls, negative screen): Provide primary prevention: educate on home safety, recommend daily physical activity (such as Tai Chi or community walking), and re-screen annually.
- Moderate-Risk Pathway (Unsteady or feels worried, but no injurious falls): Perform the 3 core physical tests. If any test is abnormal, refer to a physiotherapist for gait and strength training, review vitamin D status, and evaluate footwear.
- High-Risk Pathway (>= 1 fall with injury, or >= 2 falls, or abnormal TUG + positive screen): Conduct an in-depth multifactorial assessment: orthostatic vital signs, medication reconciliation (stopping sedatives), vision screening, home hazard audit, and mandatory home physiotherapy.
- Medication Deprescribing (STOPP/START Criteria): Work with physicians to identify and taper psychotropic medications, anticholinergics, and sedatives that increase fall risk.
- Home Hazard Remediation: Remove loose scatter rugs, improve lighting to 100-watt equivalents, install double handrails on stairways, and install bathroom grab bars.
Frequently Asked Questions About the CDC STEADI Protocol
Why is asking 'Do you worry about falling?' part of a clinical fall screening?
Research shows that fear of falling is a potent independent predictor of future falls. Seniors who worry about falling often limit their physical activities, which quickly leads to muscle wasting, joint stiffness, and impaired balance reflexes, creating a self-fulfilling cycle.
What is the single most effective intervention for someone in the STEADI High-Risk group?
A multifactorial intervention centered on individualized physiotherapy (combining balance, gait, and progressive strength training) paired with home hazard remediation and medication tapering reduces fall rates in high-risk seniors by up to 40%.
