AI Fall Risk Prediction in Hospitals Quiz

Answers and explanations appear as you take the quiz.

1. How many items does the Morse Fall Scale score?
   • Four
   • Six
   • Eight
   • Ten
2. Why can a fall prediction model with a high AUROC still produce mostly false alarms?
   • AUROC only measures processing speed
   • Hospitals cannot calculate AUROC for fall models
   • High AUROC means the model predicts every patient will fall
   • Falls are rare, so even good ranking yields low precision at usable thresholds
3. How does computer vision bed-exit detection differ from a pressure-pad bed alarm?
   • It can detect posture changes like sitting up before weight leaves the mattress
   • It only works after the patient has fallen
   • It uses the patient's heart rate instead of movement
   • It requires the patient to press a call button
4. What did a large randomized trial of increased bed alarm use find, according to the guide?
   • Falls fell by more than half
   • Alarms eliminated injurious falls
   • It did not find a reduction in falls
   • Alarms increased patient satisfaction but not staffing
5. What CMS policy does the guide mention regarding falls?
   • CMS requires video monitoring in every room
   • Since 2008, CMS has not paid hospitals extra for falls with injury acquired during a stay
   • CMS bans the use of the Morse Fall Scale
   • CMS pays a bonus for each fall alert generated
6. What limitation of the Morse Fall Scale does the guide highlight?
   • It is usually scored once a shift, misses changes between assessments, and labels many inpatients at risk
   • It can only be used in pediatric units
   • It requires laboratory data to calculate
   • It gives a single yes or no answer with no score
7. After a patient is flagged as high fall risk, which action does the guide link to actually reducing falls?
   • Adding a second alarm with a louder tone
   • Moving the patient to a room farther from the nurses' station
   • Rescoring the patient every hour without other changes
   • Scheduled toileting rounds and a medication review
8. Which privacy design do many computer vision fall systems use, according to the guide?
   • Streaming all footage to social media for review
   • Recording audio only and sharing it with families
   • Live viewing without recording, sometimes with blurring or outlines
   • Storing full-resolution video indefinitely for model training
