How we think about falls• Most of literature about adult falls is in elderly persons

who fall at home or in nursing homes• Little literature about patients who fall in the hospital• Much of our thinking about hospital falls is

extrapolated from outpatient data• Hospital falls are considered a “never event” by

Medicare

Roadmap for today

• Describe case• Review some literature about outpatient falls

in elderly persons• Review literature about inpatient falls• Review UNMH experience with inpatient falls• Discuss possible system changes at UNMH


Learning Objectives

1. Identify at least 3 factors associated with falls in elderly persons.

2. State the most common etiology of falling in elderly persons.

3. Summarize the epidemiology of in-patient falls.

4. Describe an approach for evaluating the in-patient who falls.


Case

• You are providing cross-cover. The 4W nurse calls you at 2 AM because an 84 year old woman fell in her room. The patient was admitted two ago with pneumonia and is receiving IV antibiotics and oxygen. The nurse says the patient fell when trying to get to the toilet. The nurse says the patient “seems okay” but thinks that maybe you should come see the patient.


Questions you might have

• How promptly do I need to see this patient? (Can’t this wait until the morning?)

• If I go to see the patient, how do I evaluate her? (What the #@!! am I supposed to do?)

• Is there anyway to prevent this? (How do I keep from getting these 2AM calls?)


Out-patient falls: literature review

Is falling in the elderly a significant health problem?

• 30 – 40 % of elderly persons fall each year• 5 – 6% result in injury significant enough to

see a doctor or go to ED• 2 – 3 % result in hospitalization (Ave LOS = 8d)• Annual cost to Medicare = $19B (est FY2000)

Why do elderly persons fall?• In the elderly, syncope is an uncommon cause of

falling (0.5%) • Common mechanism of falling in the elderly

– environmental perturbation (“I tripped”) – impaired neuromuscular reflex systems due to

combination of age-related changes and co-morbid illness/medications

– 80% of falls in the elderly are “unique to the elderly”

What interventions prevent falls in elderly out-patients?

• Four interventions have shown to be effective– Medication review and adjustment– Environmental changes– Exercise (or physical therapy)– Vit D if deficient (association)

• Combination of all four (multi-modality) result in relative risk reduction of 10 – 25%

Falls in ambulatory elders (concl.) • Falls occur frequently and can result in injury• Falls are usually due to inadequate

compensatory neuromuscular mechanisms• Major risk factors include lower extremity

weakness, past h/o fall, female gender, and meds (psychotropics, benzos and narcotics)

• Interventions can reduce risk of future falls• Evidence based guidelines are available


In-patient falls: literature review

Epidemiology of inpatient falls (Barnes Hospital 2001-2)

• 1,235 falls by 1082 pts (3.10 falls/1000 pt days)• 89% single fall, 11% more than once• 40% related to toileting• Serious injury (laceration requiring sutures, loss

of consciousness, fracture, SDH) – 6%• Death – 0.2% (both in patient with more than 1

fall)

Epidemiology of fall-related injury in the hospital

• 9 hospitals in Midwest, 2001 – 2003• 7,082 falls• 40% falls associated with toileting• 42% assoc w/injury, 2.4 % serious injury• Increased age, fall in location other than pt

room and unassisted fall assoc with injury

Epidemiology of in-patient falls

• National Database of Nursing Quality Indicators (NDNQI) from 2006 – 2008

• 315,817 falls in 1263 hospitals• Conclusions:

– 3.56 falls/1000 patient days– 26% injury rate– Rate of falls and fall-related injury higher on

medical than surgical floors

Epidemiology: UNMH in-patient falls study

• 298 PSN’s reporting falls in 2010• Exclude pts < 18 y/o (2), pregnant pts (3), pts

with no matching MR (7)• 286 falls, 251 pts• 152 males (61%), 99 females (39%)• 63 falls with injury (25%); 11 (4%) serious

injury (laceration requiring sutures, fracture, subdural)

Cost of hospital fall-related injury• Case reports: delayed recognition of fall-related injury can result in liability risk• 3 Midwestern hospitals, 2004 – 2006

– 57 inpatient with serious fall-related injury– $13,316 and 6.3 days more than case controls

• NHS Litigation claims– 668 claims– 60% payments, mean = $30K

Can we predict which pts will fall?

• Outpatient - Best clinical predictors are previous fall in past 6 months and Timed Up-and-Go (TUG) test

• Inpatient – Falls risk tools (Morse, STRATIFY, Hendrich II, Conley)– Not very good, best sensitivity = 73%, specificity =

42%

Do multi-modality interventions prevent inpatient falls?

• Very limited data – two observational studies show 20-25% reduction with bundle

• 3 RCT of bundle in acute care hospitals –– one showed no reduction in falls– one showed reduction for those with recurrent

falls– One showed reduction of falls in elderly, but no

reduction in fall-related injury

Case• You are providing cross-cover. The 4W nurse

calls you at 2 AM because an 84 year old woman fell in her room. She was admitted two ago with pneumonia and is receiving IV antibiotics and oxygen. The nurse says the patient fell when trying to get to the toilet. The nurse says the patient “seems okay” but thinks that maybe you should come see the patient.

• What happens at UNMH?


In-patient falls (conclusions)• Result in serious injury in 2 – 6% of patients• More common on med/surg units and frequently

related to toileting• Falls and especially delayed recognition of fall-

related injury poses significant liability risk• Our ability to predict and prevent falls is very

limited • Regulatory agencies expect hospitals to monitor

and address this problem


Conclusions• Outpatient falls and inpatient falls are probably

different epidemiologically• About 5% of in-patients who fall in the hospital

will suffer significant injury• Evidence-based guidance about assessment is

lacking• UNMH physician documentation of falls is poor• More study is needed


What should we do about fall related injury in the hospital? - Possible actions at UNMH -

• Use/review the checklist for evaluating pts who fall

• Limit use of zolpidem in patients at risk• Decrease narcotic use in the hospital• Other
