Validated Falls Risk Assessment Tools In-patient n STRATIFY n Morse n 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 ü Did patient present with a fall? ü Has s/he fallen since admission? ü Is patient agitated? ü Patient severely visually impaired? ü Patient needs frequent toileting? ü Transfer and mobility ability?

Special Considerations for high risk patients 1. 2. 3. 4. 5. 6. 7. 8. 9. ID bracelets or sticker on chart Bed alarms Special flooring Hip protectors “Toileting rounds” at shift change Terry slippers Motion sensing lights Work with PT’s Patient closer to nursing station

Educate the patient and their family n Videos: in-house and at home ü “Sit and be fit” Written materials n Community referrals n BMD screening ü Pharmacists ü n “Call before you fall”
