– 1997: hip fracture – 2003: patellar fracture – 2006: metatarsal fracture – 2006: hip fracture – 2014: displaced rib fractures. She also has evidence of an age indeterminate L2 vertebral fracture.

2003 to 2010.

Using LRs

  • Ex: Patient over 65
  • Pre-test probability 33%
  • Odds of falling in the next year 1:2

Have they fallen in the previous year?

  • Previous fall has LR of ~3
  • Post test fall odds = LR x pre-test falls odds

= 3 x 1:2 = 3:2

  • Post test probability 60%

19 School of Medicine

Novel risk factors

  • Hypoxia during sleep

– Men with ≥ 10% of sleep time with SaO2 ≤ 90% had RR of 1.25, CI = 1.04-1.51 for one or more falls RR of 1.43, CI = 1.06-1.92 for two or more falls c/t men with ≤10% of sleep time with SaO2 ≤ 90%

Fallers unlikely to discuss falls

  • Less than half of Medicare beneficiaries who fall

discuss falls with a healthcare provider (women>men).

  • Only a third to a quarter who have fallen, discuss fall

prevention strategies.

Falls Evaluation

  • Falls history and circumstances
  • Assessment of:

– balance and gait – LE strength, sensation, coordination – perceived functional ability and fear relating to falling – visual impairment – cognitive impairment – home hazards – footwear and foot problems

  • Cardiovascular examination including orthostasis
  • Medication review

Effective Interventions

  • Exercise: ↓ # falls and #fallers and risk for fracture

– Multiple component group exercise – Individually prescribed, multiple component, home-based program – Tai Chi group exercise

Gillespie et al Cochrane 2012

School of Medicine

Effective Interventions

  • Multifactorial risk factor program (↓ #falls)
  • Home hazard assessment & modification in

higher risk in those with visual impairment and high risk of falling (↓ # falls and #fallers)

Effective Interventions

  • Medications: (↓ # falls) Gradual withdrawal of

psychotropic medication; educational program for 1° care MDs

  • Cardiac pacing for fallers with cardioinhibitory

carotid sinus hypersensitivity (↓ #falls)

  • Expedited cataract surgery for first eye(↓ #falls)

43

School of Medicine

Interventions that are Ineffective

  • Vitamin D with or without calcium in those with

adequate Vitamin D levels

  • Home hazard modification in those without fall

history

  • Hormone replacement therapy
  • Correction of visual deficiency (alone)
  • Patient education or cognitive behavioral training

What about Vitamin D supplementation?

  • IOM 2009 “Supplemental vitamin D in a dose of 700-

1000 IU a day reduced the risk of falling among older individuals by 19%...”

  • IOM 2011 “…no significant reduction in fall risk related

to vitamin D intake or achieved level in blood.”

  • USPSTF 2012 recommends exercise or physical

therapy and vitamin D supplementation to prevent falls in community-dwelling adults aged 65 years or older who are at increased risk for falls.

  • AGS 2013 “Clinicians are strongly advised to

recommend vitamin D supplementation of at least 1,000 international units (IU)/d, …to reduce the risk of fractures and falls.”

  • BMJ 2014 “In pooled analyses, supplementation with

vitamin D, with or without calcium, does not reduce falls by 15% or more.”

45 School of Medicine

What I Recommend

  • Offer cholecalciferol to all older adults at risk for

falls.

What about perturbation-based training?

  • RCT 212 patients
  • 24 slip session vs 1 slip session
  • Self-reported falls in the year after the intervention:

– 25% in control vs 13% in intervention

  • Falls are common in older adults.
  • Falls cause significant ADL deficits and most

fractures and in older adults.

  • Falls can be prevented.
  • Ask older adults about falls in the last year and
  • bserve gait and balance.
  • Refer patients at risk for future falls to effective fall

prevention approaches.
