Morse Fall Scale Calculator — Inpatient Fall Risk Assessment
The Morse Fall Scale is a validated fall risk assessment tool used to identify hospitalized patients at risk of falling, assessing six domains: history of falls, secondary diagnoses, ambulatory aids, IV therapy, gait, and mental status.
About
The Morse Fall Scale was developed by Janice Morse and colleagues in 1989 and published in Nursing Research. It was designed as a rapid and reliable method for assessing a patient's risk of falling during hospitalization. The scale consists of six items: (1) History of falls (25 points if yes) — the single strongest predictor of future falls, (2) Secondary diagnosis (15 points if ≥2 medical diagnoses) — multiple comorbidities increase fall risk, (3) Ambulatory aid — no aid/bed rest/nurse assist (0), crutches/cane/walker (15), furniture/touch for support (30), (4) IV/Heparin lock (20 points if present) — tethering increases risk, (5) Gait — normal/bedrest/wheelchair (0), weak/stooped but able to lift head (10), impaired/shuffling/difficulty rising (20), (6) Mental status — aware of own abilities/limitations (0), overestimates/forgets limitations (15). Total scores range from 0 to 125 with three risk categories: low (0-24), moderate (25-44), high (≥45). The scale has demonstrated inter-rater reliability of 0.96 and predictive validity with sensitivity of 78-83% and specificity of 72-83% at the cutoff of ≥45.
Formula
History of Falls (25) + Secondary Diagnosis (15) + Ambulatory Aid (0/15/30) + IV/Heparin Lock (20) + Gait (0/10/20) + Mental Status (0/15). Total 0-125.
The Morse Fall Scale total is the sum of points from six items. Each item has specific criteria and point values: (1) History of falls: 25 if patient has fallen during this admission or within 3 months prior. (2) Secondary diagnosis: 15 if patient has ≥2 medical diagnoses (not just the primary admitting diagnosis). (3) Ambulatory aid: 0 if walking without aid or on bed rest/nurse assist, 15 if using crutches/cane/walker, 30 if holds onto furniture for support. (4) IV/Heparin lock: 20 if any IV line or heparin lock is present. (5) Gait: 0 if normal/bedrest/wheelchair, 10 if weak but able to lift head (stooped but independent), 20 if impaired with difficulty rising (shuffling, short steps). (6) Mental status: 0 if aware of own abilities/limitations, 15 if overestimates ability or forgets limitations. Total classifies risk: low (0-24), moderate (25-44), high (≥45).
Score Interpretation
Patient falls are the most common adverse event in hospitals, with an estimated 700,000 to 1 million inpatient falls per year in the US. Approximately 30-50% of inpatient falls result in injury, including fractures (2-10%), lacerations, and traumatic brain injury with increased length of stay by 6-12 days and added costs of $14,000-$35,000 per fall. The Morse Fall Scale is one of the most widely used fall risk assessment tools in North America and is endorsed by The Joint Commission (TJC) as part of the National Patient Safety Goals for fall reduction. Regular fall risk assessment with the Morse Scale, combined with implementation of targeted prevention strategies, has been shown to reduce fall rates by 20-30%. The scale is easy to use (takes 2-3 minutes), requires no special equipment, and can be administered by any trained healthcare provider. It should be completed on admission, daily, with any change in condition, after a fall, and on transfer to a new unit.
Low Risk — 0–24
Score 0-24. Low fall risk. Standard fall prevention measures.
Management: Routine fall prevention education. Encourage use of call light. Maintain clear pathways and adequate lighting. Non-slip footwear.
Moderate Risk — 25–44
Score 25-44. Moderate fall risk. Implement standard prevention protocol.
Management: Bed in lowest position, brakes locked. Call light within reach. Non-slip footwear. Assist with ambulation. Toilet schedule. Review medications for fall risk.
High Risk — 45+
Score ≥45. High fall risk. Implement high-risk fall prevention protocol.
Management: Implement high-risk fall prevention protocol. Bed in lowest position, brakes locked. Call light within reach. One-to-one supervision or sitter. Consider patient alarm and low bed. Falls poster at bedside. Rounding every 1-2 hours.
Reference Ranges
| Population | Normal Range | Notes |
|---|---|---|
| Hospitalized patients (adult) | 0-125 points | 0-24: Low, 25-44: Moderate, ≥45: High fall risk |

An 85-year-old woman is admitted with pneumonia and a history of hypertension and diabetes. She has a history of falling at home. She is alert and oriented but gets confused about her surroundings at night and attempts to get out of bed without calling for help. She walks with a walker but her gait is unsteady. She has a peripheral IV for antibiotics. Morse Fall Scale: History of falls: Yes (25). Secondary diagnoses (≥2): Yes, pneumonia, hypertension, diabetes (15). Ambulatory aid: Walker (15). IV/Heparin lock: Yes (20). Gait: Weak/unsteady (10). Mental status: Forgets limitations/overestimates ability — gets out of bed alone (15). Total = 25+15+15+20+10+15 = 100/125. Interpretation: High fall risk (≥45). High-risk fall prevention protocol: bed in lowest position, fall prevention poster, call light within reach, one-to-one supervision, hourly rounding, physical therapy consult for gait training, review of sedative medications.

Common Mistakes
Scoring "secondary diagnosis" as any secondary diagnosis
The Morse Scale requires ≥2 medical diagnoses for the secondary diagnosis item to score 15 points. Having only one secondary diagnosis or adding psychiatric diagnoses alone does not meet the criterion. The item is designed to capture the effect of multimorbidity on fall risk.
Not reassessing fall risk after a patient falls
The Morse Scale should be reassessed immediately after any fall. The "history of falls" item will now be positive (25 points), which may increase the risk category and trigger more intensive prevention measures.
