What is a fall? A fall is defined as an unintentional

loss of balance that leads to failure of postural stability (Nelson and Amin 1009)

Recurrent fallers are those that have fallen 2 or more times in either 6 or 12 months (Studentski et all 1994, Gregg et all 2000)

Health Care:What is a fall? A fall is a sudden and unexpected

change in position, usually resulting in landing on the floor.

Finding a patient on the floor or lowering or assisting a person to the floor is considered a fall and needs to be documented as such.

Myths about falling…

Due to carelessness. A normal process of aging. They “just happen”. Cannot be predicted or anticipated.

annually: 50-100% in nursing homes.

95% of hip fractures result from a fall.

Of those who fall, 25% suffer injuries that reduce mobility and independence.

50% of those who sustain injury from a fall can no longer live independently.

Facts About Hip Fractures 1 in 7 women will break hip.

25% will regain full functional ability.

50% will end up in nursing home.

Risk of dying from osteoporosis = Risk of dying from breast cancer

Why Do People Fall? summary of 12 studies Accident/environment- 31% Gait/balance problem – 17% Dizziness/vertigo – 10% Confusion – 4% Postural hypo-tension –3% Vision –3% Other and unknown –20%

Where do people fall? For those 65+

- 60% happen at home - 30% occur in public places - 10% in health care institutions

Facts About Falls and Hospitals.6 –2.9 falls per bed annually in hospitals;

(Rubenstein 2000)

14% of d/c pts. fall the first month after discharge; falls are the BEST predictor of nursing home placement;

40% of nursing home placements due in some way related to a fall.

Cost of Falls in Nursing Homes

“Falls in nursing homes once again make up the largest number of claims against nursing homes insured by St Paul Medical Service.”

The St Paul Annual Report to Shareholders

Falls are Predictable:Risk Factors for Falls Impairments in…

• Cognition.• Vision or hearing.• Feet.• Lower extremity strength.• Balance or gait.• Postural hypo-tension.• Syncope and arrhythmia.

Risk Factors for falls, cont. Medication useTotal number over 4 AND/OR

- Sedatives: confusion, motor dysfunction - Anti-psychotics: hypotension - Anti-depressants: hypotension - Anti-hypertensives: postural hypo-tension - Anti-anxiety: Confusion - Diuretics: Urinary urgency resulting in a fall

Risk Factors for Falls, cont.

Alcohol intake. Dehydration. Poor Nutrition.

- Vitamin D - Calcium

Falls Risk,Extrinsic Factors Poor lighting. Uneven or slippery surfaces. Loose rugs. Steep stairs. Clutter/pets in pathway. Lack of handrails (inc bathroom). Furniture wrong height. Long bathrobe.

Falls in the Hospital:Client Risk Factors Postural hypo-tension. Lowest weight percentile. Medications: 4+ or sedatives. Previous fall. Impaired arm strength or range of motion. Uneven gait. Unable to move from bed to bath without

assistance.

Falls in the Hospital:Institutional Risk Factors

Recent admission. Furniture placement. Slick and/or hard floors. Unsupervised activities.

Falls in the Hospital:cont…Institutional Risk Factors

Reduced # of nurses. Meal times. Absent handrails. Poor lighting.

In-patientIn-patient STRATIFY Morse Develop your own!! Success is wildly

mixed in research studies

75% of RN’s from 150 institutions wanted more falls prevention support.

STRATIFY as an example:Predicts up to 93% of falls

Did patient present with a fall? Has s/he fallen since admission? Is patient agitated? Patient severely visually impaired? Patient needs frequent toileting? Transfer and mobility ability?

Special Considerations for high risk patients1. ID bracelets or sticker on chart2. Bed alarms3. Special flooring4. Hip protectors5. “Toileting rounds” at shift change6. Terry slippers7. Motion sensing lights8. Work with PT’s9. Patient closer to nursing station

Educate the patient and their family Videos: in-house and at home
