What is the Morse Fall Scale?

The Morse Fall Scale (MFS) is a rapid and simple method of assessing a patient's likelihood of falling. It was developed by Janice M. Morse in 1989 and is one of the most widely used fall risk assessment tools in acute care hospitals worldwide.

The scale consists of six assessment items that are easily scored by nursing staff during routine patient assessment. The total score ranges from 0 to 125 and is used to classify patients into low, moderate, or high fall risk categories. The MFS is designed to be administered quickly (typically under 3 minutes) and can be reassessed at each shift change or when a patient's condition changes.

Falls are one of the most common adverse events in hospitals, affecting approximately 2–12% of hospitalized patients. Fall-related injuries can lead to fractures, head injuries, increased length of stay, higher healthcare costs, and in severe cases, death. Systematic fall risk assessment is therefore a critical component of patient safety programs.

Scoring Criteria

Item	Response	Points
1. History of Falling (within past 3 months)	No	0
	Yes	25
2. Secondary Diagnosis (more than one medical diagnosis)	No	0
	Yes	15
3. Ambulatory Aid	None / Bed rest / Nurse assist	0
	Crutches / Cane / Walker	15
	Furniture (holds onto furniture for support)	30
4. IV Therapy / Heparin Lock	No	0
	Yes	20
5. Gait / Transferring	Normal / Bed rest / Immobile	0
	Weak	10
	Impaired	20
6. Mental Status	Oriented to own ability	0
	Overestimates ability / Forgets limitations	15

Score Interpretation & Interventions

Score Range	Risk Level	Recommended Interventions
0 – 24	Low Risk	Good basic nursing care (standard fall prevention precautions)
25 – 44	Moderate Risk	Implement standard fall prevention interventions: fall risk signage, non-slip footwear, bed alarm, frequent monitoring
≥ 45	High Risk	Implement high-risk fall prevention interventions: all standard measures plus sitter/1:1 observation if needed, toileting schedule, low bed, floor mat, movement sensor, physical therapy consult

Validation & Reliability

The Morse Fall Scale has been extensively validated in hospital settings:

• Sensitivity: 72–83% (ability to correctly identify patients who will fall)
• Specificity: 51–83% (ability to correctly identify patients who will not fall)
• Interrater reliability: High agreement between different nurses scoring the same patient (kappa 0.75–0.96)
• Time to administer: Less than 3 minutes

The MFS has been validated across various healthcare settings including medical-surgical units, rehabilitation facilities, and long-term care. However, its performance may vary by population and setting, and some institutions have adopted modified cutoff scores.

Impact of Hospital Falls

Hospital falls are a significant patient safety concern with substantial clinical and economic consequences:

• Falls are the most commonly reported adverse event in hospitals
• Approximately 30–50% of hospital falls result in injury
• 6–12% of falls result in serious injury (fracture, subdural hematoma, etc.)
• Falls increase hospital length of stay by an average of 6.3 days
• Fall-related injuries cost an estimated $34,000+ per event in additional healthcare costs
• In the US, falls with injury are classified as a "never event" by CMS and are not reimbursable

Fall Prevention Strategies

Standard Precautions (All Patients)

• Orient patient to surroundings and call light on admission
• Keep bed in low position with brakes locked
• Ensure adequate lighting, especially at night
• Keep call light and personal items within reach
• Encourage non-slip footwear
• Clear pathways of clutter and cords

Moderate-Risk Interventions

• Fall risk identification (signage, colored wristband, chart alert)
• Bed alarm or chair alarm
• Frequent rounding (every 1–2 hours)
• Assisted toileting schedule
• Medication review for fall-risk-increasing drugs
• Physical therapy evaluation

High-Risk Interventions

• All standard and moderate interventions
• Consider 1:1 sitter or continuous observation
• Padded floor mats beside the bed
• Ultra-low bed or floor-level mattress
• Movement detection technology
• Toileting assistance every 2 hours
• Video monitoring if available
• Post-fall huddle if a fall occurs

Worked Example

Consider a 78-year-old patient admitted with pneumonia who also has type 2 diabetes:

This patient scores 85, placing them in the High Risk category (≥45). All high-risk fall prevention interventions should be implemented immediately, including bed alarm, fall risk signage, frequent rounding, non-slip footwear, and potentially a sitter or continuous observation.

Frequently Asked Questions

How often should the Morse Fall Scale be reassessed?

The MFS should be assessed on admission, at each shift change (typically every 8–12 hours), after any fall, after a change in condition or medications, and upon transfer to a new unit. Some institutions reassess every 24 hours at a minimum.

What counts as "history of falling"?

Any fall within the previous 3 months, whether it occurred at home, in the community, or in a healthcare setting. This includes the current admission if a fall occurred during this hospitalization. An "immediate" fall (one that occurred within the current admission) is always scored as positive.

What does "furniture" mean for ambulatory aid?

This refers to a patient who walks while holding onto furniture (bedside tables, walls, door frames, etc.) for support rather than using a proper ambulatory device. This carries the highest score (30) because it indicates unstable ambulation without appropriate equipment.

Is the Morse Fall Scale suitable for pediatric patients?

The MFS was designed for adult patients. For pediatric populations, alternative tools such as the Humpty Dumpty Scale or CHAMPS (Children's Hospital of Philadelphia Method for Assessment of Fall Risk) are more appropriate.

Can the MFS be used in outpatient settings?

The MFS was primarily developed and validated for inpatient (hospital) settings. While some items are applicable to outpatient and community settings, other fall risk tools (such as the Timed Up and Go test or the STEADI toolkit) may be more appropriate for outpatient or community-dwelling populations.
