About the Morse Fall Scale
The Morse Fall Scale is a quick, widely used nursing tool for identifying hospital patients at risk of falling. Developed by Janice Morse and colleagues and evaluated prospectively in 2,689 patients across acute, long-term geriatric and rehabilitation units (Social Science & Medicine, 1989), it rates six items: history of falling, secondary diagnosis, use of an ambulatory aid, intravenous therapy or a heparin lock, gait, and mental status. Totals range from 0 to 125.
This calculator is for nurses, nursing students, physiotherapists and quality teams completing admission or daily fall-risk assessments. Pick the description that fits the patient for each item and the score and risk level update instantly. Because hospitals set their own action thresholds, you can choose between the commonly cited Morse levels (0–24 no risk, 25–50 low risk, 51 or more high risk) and the alternative scheme many units use (45 or more high risk).
The Morse score should be repeated when the patient’s condition changes, after a fall and at transfer. It identifies risk — the fall-prevention measures that follow are set by your local protocol, and the cut-off that works best should ideally be calibrated to your own unit.
With the default inputs, the morse fall scale score is 45 / 125. Change any value above to recalculate instantly.
How to use the morse fall scale
- 1Ask about and check records for any fall this admission or in the past three months.
- 2Note whether the patient has more than one active medical diagnosis.
- 3Observe how they walk: the aid they use and whether gait is normal, weak or impaired.
- 4Record whether they have an IV line or heparin/saline lock.
- 5Judge mental status by comparing their stated walking ability with what you observe.
- 6Choose your unit’s thresholds and read the score and risk level.
Formula and method
The Morse Fall Scale adds weighted points for six items, giving a total from 0 to 125. The single highest option is clutching onto furniture to walk (30), followed by a history of falling (25), IV access (20) and impaired gait (20). A secondary diagnosis, using a walking aid and overestimating one’s abilities each add 15, and weak gait adds 10.
Patients on bed rest who do not get out of bed, or who use a wheelchair or walk only with a nurse, score 0 for the aid item; similarly, bed rest or immobility scores 0 for gait. Mental status is judged by asking the patient whether they can walk alone to the bathroom and comparing the answer with what they can actually do.

Worked examples
Post-operative patient with an IV and weak gait
Secondary diagnosis (15) + IV access (20) + weak gait (10) = 45. Under Morse’s levels this is low risk (25–50), six points short of the high-risk band at 51.
Same patient with the 45-point threshold
The score is still 45, but many hospitals class 45 or more as high risk, so the same patient would trigger high fall-risk precautions on those units.
Confused patient who has fallen and walks with a frame
Fall history (25) + secondary diagnosis (15) + walker (15) + IV (20) + impaired gait (20) + forgets limitations (15) = 110, well into the high-risk range.
Frequently asked questions
What is a high Morse Fall Scale score?+
Morse’s commonly cited levels are 0–24 no risk, 25–50 low risk and 51 or more high risk. Many hospitals instead use 45 or more as high risk; follow your organisation’s policy.
How often should the Morse Fall Scale be done?+
Typically on admission, at least daily or every shift according to local policy, after any fall, on transfer between units and whenever the patient’s condition or medications change significantly.
What counts as a secondary diagnosis?+
Score 15 if the patient has more than one active medical diagnosis listed in the record. A single diagnosis scores 0.
How is mental status scored on the Morse scale?+
Ask the patient whether they can go to the bathroom alone or need help. If their answer matches what they can actually do, score 0; if they overestimate their ability or forget limitations, score 15.
Who is the Morse Fall Scale validated for?+
It was developed for adult hospital inpatients and tested in acute medical-surgical, long-term geriatric and rehabilitation units. It is not designed for children, for whom tools such as the Humpty Dumpty scale are used.
