Calculator Inputs
Use the form below to estimate fall risk using recent history, functional performance, medication burden, symptoms, and environmental hazards.
Example Data Table
This sample shows how a mixed history and reduced mobility can move the result into a higher risk category.
| Input | Example Value | Effect on Risk |
|---|---|---|
| Age | 82 years | Moderate age-related point increase |
| Falls in past year | 2 or more | Strong risk increase |
| Timed Up and Go | 17.8 seconds | Mobility impairment flag |
| 30-second chair stands | 7 reps | Lower-body weakness flag |
| Home hazards | 4 hazards | Environmental risk increase |
| Result | Approx. 71 / 100 | High risk screening outcome |
Formula Used
This calculator uses a weighted composite screening model. It combines recent fall history, symptoms, medication burden, mobility test performance, strength, balance, and home hazards.
Raw Weighted Score = sum of factor points
Normalized Score = (Raw Weighted Score / 159) × 100
Risk Bands: Low < 25, Moderate 25 to 49.9, High 50 to 74.9, Very High ≥ 75
How to Use This Calculator
- Enter the person’s age and recent fall history.
- Add symptom details, including unsteadiness, fear of falling, and dizziness.
- Record medication burden and note psychoactive medicines when present.
- Enter functional test results for Timed Up and Go, chair stands, and balance.
- Count visible home hazards and note footwear, urgency, or cognitive concerns.
- Press Calculate Fall Risk to show the result above the form.
- Review the score, flagged factors, recommendations, and downloadable report.
- Use the output to support prevention discussions or referral planning.
Frequently Asked Questions
1. What does the score represent?
It summarizes weighted fall-risk factors into a 0 to 100 screening score. Higher results suggest more issues needing review, not a confirmed diagnosis.
2. Is this calculator a medical diagnosis?
No. It is an educational screening aid. A clinician must interpret symptoms, illnesses, medications, test quality, and individual circumstances.
3. Why is fall history weighted heavily?
A previous fall is one of the strongest warnings for future falls. Recurrent falls or injury usually justify closer assessment and prevention planning.
4. Why include Timed Up and Go?
Timed Up and Go reflects mobility, transfers, turning, and gait speed. Slower times can signal balance or strength limitations linked with falling.
5. Can I use it at home?
Yes, for screening. Functional tests should be done safely, preferably with supervision if the person is unsteady, weak, or recently injured.
6. Why do medicines affect fall risk?
Some medicines can cause sedation, dizziness, confusion, or low blood pressure. Multiple medicines may also increase interaction-related problems.
7. How often should the score be updated?
Recalculate after any fall, medication change, major illness, mobility decline, or home-safety update. Regular review improves prevention planning.
8. What should I do with a high result?
Use it as a prompt for a clinical review, mobility assessment, medication check, and home-safety changes. Urgent symptoms need prompt medical attention.
