Falls prevention for older people presenting to Emergency Departments – what do we know
Morello R et al, IN PRESS (systematic review and meta-analysis, Injury Prevention, doi: 10.1136/injuryprev-2019-043214
High risk
High risk
High risk
High falls risk group
Low uptake of guide- line level care
Limited effect of interventions to reduce falls
Low level adherence
Reduced effect for referral type interventions
Guideline level practice in falls prevention: Canada
• 54 older adults after an emergency department (ED) fall presentation
• 2 of 54 (3.7%) of the fallers received care consistent with AGS Guidelines
• NB – More recent International fall prevention Guidelines (JAGS 2011)
Salter et al, Osteoporosis Int, 2006

RESPOND – a new RCT building on previous findings
The gap being addressed:RESPOND was specifically designed to provide personalised and timely education and support to improve knowledge, self-efficacy, and participation in evidence based falls prevention activities
Aim:to investigate the effectiveness of RESPOND for reducing falls and fall injuries in older people after presenting to the ED with a fall.
The name RESPOND was coined based on an underlyingphilosophy of, ‘respond to the first fall to prevent the second’

Method Recruitment through Alfred Hospital (Melbourne) and Royal
Perth Hospital (Perth) Inclusion criteria:
– Present to ED from community setting with a fall*, and discharged home within 72 hours
– Age 60-90 years Exclusion criteria
– Planned discharge to residential care– receiving palliative care or presence of a terminal illness– Requiring hands-on assistance to walk from another individual– Unable to use a telephone– Non-English speaking– Cognitive impairment (Mini Mental State Examination [MMSE] score
<23) [24], social aggression, or a history of psychosis– Living >50 km from trial sites
* Fall defined as “an event resulting in a person coming to rest inadvertently on the ground, floor, or other lower level” (WHO, 2007)
6
Method: Assessment
Home visit within 2 weeks of ED discharge
Assessors blind to group allocation– Falls risk assessment (FROP-Com)– Health literacy (Health Literacy
Questionnaire)– Health related quality of life (EQ-5D-5L)– Falls efficacy (Falls Efficacy Scale
International-short form)
Reassessment 12 months
Primary outcomes:- falls (falls diary)- falls injuries (any
physical harm resulting from a fall (including fractures, dislocations, sprain, skin tears, and bruising)
Secondary outcomes:- ED re-presentations,
hospitalisations, fractures, falls risk, falls efficacy, quality of life, and deaths/person-year over the 12-month study period.
7
Method: Intervention and control Randomisation: permuted block randomization
stratified by recruitment site Concealed allocation
Intervention (6 months)– Standard care as initiated by ED staff and their healthcare providers– Discussion of falls risk findings, and four modules of intervention,
and shared prioritisation of initial intervention– Phone followup and support for participation by clinicians (registered
health professional - PT, OT, Ns, Dietitian) with motivational interviewing training Initial phone call within 2 weeks of assessment, then as mutually agreed
for 6 months
Control– Standard care as initiated by ED staff and their healthcare providers
8
Key elements of RESPOND: learnings from previous trials• Limited suite of evidence based interventions (4)
• Positive health messages in all program materials
• Clinicians trained in motivational interviewing to support sustained participation
• After initial visit: Phone based intervention x 6 months

Statistical analysis
Statistician blind to group allocation
Intention to treat analysis
For primary outcomes, rates were calculated per person-year of exposure time and compared between groups using negative binomial regression models (including adjustment by site and an offset for exposure time)
T-tests used to evaluate change in falls risk, falls efficacy, quality of life measures over time.

Falls prevention for older people presenting to Emergency Departments – systematic review
Morello R et al, IN PRESS (systematic review and meta-analysis, Injury Prevention, doi: 10.1136/injuryprev-2019-043214
A=falls; B=fallers; C=neck of femur fractures
RCTs of multifactorial falls prevention, targeting community-dwelling adults >60 years presenting to the ED with a fall
12 studies, 3986 participants, from 6 countries
Several successful RCTs, a number non-successful
No significant effects in any meta-analyses
Summary and clinical implications
• Relatively low resource intervention successful in high falls risk population (await economic and program evaluation)
• ??model able to be integrated with existing ED services (eg allied health care coordination teams) or in community services
• Key messages for falls prevention generally:– Limited suite of intervention options– Shared prioritisation of interventions– Positive messages to maximise engagement– Motivational interviewing to support participation
