Morse Fall Scale Calculator
Add the six Morse Fall Scale items and get a low, moderate, or high fall risk score with a suggested action.
What it does
The Morse Fall Scale is a six item nursing assessment used to estimate a hospital patient's risk of falling. It was developed in acute care and is widely built into electronic nursing records. Each item has a fixed point value, so the score is quick to complete and easy to audit.
The scale covers fall history, number of active diagnoses, walking aid, intravenous access, gait, and mental status. History of falling carries the largest single weight at 25 points. An intravenous line adds 20 points because it changes how easily a person can get up and walk. Gait and mental status capture how safely the person moves and whether they recognize their own limits.
A total of 0 to 24 is low risk, 25 to 44 is moderate risk, and 45 or more is high risk. The bands are not a prediction for one person. They are a prompt to match precautions to the level of risk. A high score should trigger a review of call lights, bed height, footwear, toileting plans, and supervision.
The scale is most useful when scored at admission and after any change. A patient can move from low to high risk after starting a sedative or after a first fall. The score should never replace clinical judgment. A nurse who sees an unsteady patient should act even when the arithmetic says low risk.
Different hospitals use different cutoffs and different fall bundles. The item weights here follow the published Morse Fall Scale. Local policy may add a medication review, a bed alarm, or a one to one sitter. Document the score and the precautions actually used so the next shift can see the plan.
How to use
- Score history of falling from the current admission and the recent period. A fall months ago that is unrelated to the present illness should not be counted as yes in most protocols.
- Count active medical diagnoses. Score 15 when there is more than one, not when the primary diagnosis is severe.
- Record the walking aid the person actually uses. Use furniture if they hold walls or chairs. Use nurse assist if a staff member must help.
- Check for any intravenous line or heparin lock. Score 20 when one is present, even if the line is capped.
- Observe a short walk or transfer. Choose normal, weak, or impaired gait, then assess whether the person recognizes their limits.
- Add the six values and compare the total with the local bands. Put the score and the precautions in the care plan, and repeat after a fall or a change in condition.
Formula
- History
- 0 for no recent fall, 25 for a fall during this admission or the recent period.
- Secondary diagnosis
- 0 for one diagnosis, 15 for more than one active diagnosis.
- Ambulatory aid
- 0 for none, bed rest, or nurse assist, 15 for crutches, cane, or walker, 30 for furniture.
- IV
- 0 for no line, 20 for an intravenous line or heparin lock.
- Gait
- 0 for normal, bed rest, or immobile, 10 for weak, 20 for impaired.
- Mental status
- 0 when oriented to own ability, 15 when limitations are forgotten or overestimated.
The maximum is 125 points. The bands above are the most common published cutoffs, but some hospitals use a single cutoff near 45 or add a medication flag. The scale was built for adult inpatient use. It is not a pediatric tool and it does not account for environmental hazards such as wet floors or poor lighting. Use the score with a direct observation of the patient's mobility.
Worked example
Example: 85 points, high risk
A patient fell on the ward yesterday, has two active diagnoses, uses a walker, has a heparin lock, walks with a weak gait, and is oriented to their limits.
- History of falling: yes, 25 points.
- Secondary diagnosis: yes, 15 points.
- Ambulatory aid: walker, 15 points.
- IV or heparin lock: yes, 20 points.
- Gait: weak, 10 points.
- Mental status: oriented, 0 points.
- Add: 25 + 15 + 15 + 20 + 10 + 0 = 85. The total is 45 or more, so the risk is high.
Reference table
| Item | Option | Points |
|---|---|---|
| History of falling | No | 0 |
| History of falling | Yes | 25 |
| Secondary diagnosis | No | 0 |
| Secondary diagnosis | Yes | 15 |
| Ambulatory aid | None, bed rest, or nurse assist | 0 |
| Ambulatory aid | Crutches, cane, or walker | 15 |
| Ambulatory aid | Furniture | 30 |
| IV or heparin lock | No | 0 |
| IV or heparin lock | Yes | 20 |
| Gait | Normal, bed rest, or immobile | 0 |
| Gait | Weak | 10 |
| Gait | Impaired | 20 |
| Mental status | Oriented to own ability | 0 |
| Mental status | Overestimates or forgets limitations | 15 |
| Risk band | 0 to 24 | Low |
| Risk band | 25 to 44 | Moderate |
| Risk band | 45 or more (worked: 85) | High |
Limits
- The score estimates risk for groups of patients. It cannot predict which individual will fall.
- Gait and mental status are observer ratings, so two nurses can score the same patient differently.
- The scale does not include medications, footwear, lighting, or toileting needs, all of which affect real fall risk.
- Cutoffs vary by hospital and unit. Use the bands adopted by the local policy rather than assuming one universal threshold.
Common mistakes
- Counting a fall from years ago as a positive history when the local protocol asks for a recent fall.
- Scoring furniture as 15 points. Furniture is the highest aid category at 30 points.
- Marking both a walking aid and an impaired gait without observing the actual transfer.
- Scoring mental status as oriented when the person repeatedly tries to stand without help.
- Completing the score at admission and never repeating it after a new sedative or a fall.
Try it yourself
Quick checks. Answers sit tucked under each question.
No history, one diagnosis, no aid, no IV, normal gait, oriented. What is the score and band?
0 + 0 + 0 + 0 + 0 + 0 = 0. The score is 0, which is low risk.
No history, secondary diagnosis yes, walker, no IV, normal gait, oriented. What is the score and band?
0 + 15 + 15 + 0 + 0 + 0 = 30. The score is 30, which is moderate risk.
History yes, no secondary diagnosis, no aid, IV yes, impaired gait, mental status 15. What is the score and band?
25 + 0 + 0 + 20 + 20 + 15 = 80. The score is 80, which is high risk.
Questions
What does a Morse score of 45 mean?
A score of 45 or more falls in the high risk band in the usual published cutoffs. It should prompt a review of fall precautions and closer supervision.
Should I count a fall before admission?
Many protocols count a fall in the recent period that led to admission, especially when it suggests ongoing instability. Follow the wording of your local policy.
Does an IV really add 20 points?
Yes, in the published scale. An intravenous line can make walking to the bathroom harder and is treated as a risk factor.
Can the Morse scale be used in nursing homes?
It is used in some long term settings, but it was developed for acute care. Long term care often uses a different tool and a different fall bundle.
What is the difference between weak and impaired gait?
Weak gait means short steps or difficulty starting but the person can walk. Impaired gait means the person needs help and cannot walk safely alone.
Does a low score mean no fall precautions are needed?
No. Standard precautions still apply, and clinical judgment can add measures when the patient looks unsteady.
