Fall Risk Assessment Score Calculator
Estimates fall risk using the Morse Fall Scale (MFS), a validated clinical tool assessing six risk factors to categorize patients as low, medium, or high fall risk.
History of Falling (within last 3 months or immediate)
No — 0 points Yes — 25 points
Secondary Diagnosis (≥2 medical diagnoses)
No — 0 points Yes — 15 points
Ambulatory Aid
None / Bed rest / Nurse assist — 0 points Crutches / Cane / Walker — 15 points Furniture — 30 points
IV / Heparin Lock
No — 0 points Yes — 20 points
Gait / Transferring
Normal / Bed rest / Immobile — 0 points Weak — 10 points Impaired — 20 points
Mental Status
Oriented to own ability — 0 points Overestimates / Forgets limitations — 15 points
Calculate Fall Risk Score
function falCalc() { var errEl = document.getElementById('fal-error'); var resEl = document.getElementById('fal-result'); errEl.style.display = 'none'; resEl.style.display = 'none';
var history = parseInt(document.getElementById('fal-history').value); var diagnosis = parseInt(document.getElementById('fal-diagnosis').value); var ambulatory = parseInt(document.getElementById('fal-ambulatory').value); var iv = parseInt(document.getElementById('fal-iv').value); var gait = parseInt(document.getElementById('fal-gait').value); var mental = parseInt(document.getElementById('fal-mental').value);

#### Formula
Morse Fall Scale (MFS) Total Score = sum of six subscale scores:
Factor Scale Points
History of FallingNo / Yes0 / 25 Secondary DiagnosisNo / Yes0 / 15 Ambulatory AidNone / Crutches-Cane-Walker / Furniture0 / 15 / 30 IV / Heparin LockNo / Yes0 / 20 Gait / TransferringNormal / Weak / Impaired0 / 10 / 20 Mental StatusOriented / Overestimates ability0 / 15
Risk Stratification:
- Low Risk: MFS < 25 — Standard safety precautions
- Medium Risk: MFS 25–44 — Standard fall prevention interventions
- High Risk: MFS ≥ 45 — High-risk fall prevention protocol
Maximum possible score: 125 points.
