Quick guide
How to use this calculator
- Use the labels and unit notes to enter the requested measurement, date, time, or observation exactly as recorded.
- Check the visible method, population, and unit basis before using the result; switch modes rather than converting values mentally.
- Read the calculation audit and limitations together. The result supports measurement or tracking and does not replace diagnosis, treatment, or urgent medical assessment.
Calculation method
How the near-fall event ledger calculator works
Count dated near-fall records and calculate median spacing between consecutive records; same-date events remain separate.
The result describes only the entered record. It does not grade independence, diagnose frailty or sarcopenia, predict a fall, or determine care needs.
Worked example
Near-Fall Event Ledger example
Three near-fall records produce three records and two spacing intervals, including a zero-day gap when two events share a date.
Count dated near-fall records and calculate median spacing between consecutive records; same-date events remain separate.
Supported inputs
Precision and limits
Supported purpose
A near-fall definition must be used consistently. No future-risk class is calculated.
Measurement quality
The output is only as reliable as the entered measurement, device, timing, units, and applicable reference population. Recheck unexpected values against the original record.
Clinical boundary
This calculator does not diagnose a condition, choose treatment, change medication, or determine that an urgent symptom is safe to monitor at home. Contact an appropriate health professional or local emergency service when the situation may be urgent.
