Osteoporosis, falls and fractures EVOS/EPOS Group Falls explain between-center differences in the incidence of limb fracture across Europe. JBMR 2002 Low BMD is less predictive than risk of falling for future limb fractures in women across Europe. Bone 2005 www.iofbonehealth.org
30-40% community dwelling 65+ fall in a year • 40-60% no injury • 30-50% minor injury • 5-6% major injury (excluding fracture) • 5% fractures • 1% hip fractures • Falls most serious frequent home accident • 50% hospital admissions for accidental injury due to fall • History of falls a major predictor future fall Masud, Morris Age & Ageing 2001; 30-S4 3-7 Rubenstein.

Risk of fall admission by age and sex (1.5 million cases 1991-2002) Todd et al 2008 report to DH Increasing rates over 10 year period
Mortality rates after fall admission by sex Todd et al 2008 report to DH
Consequences • Injury • 4 million NHS England bed days/annum • £2 billion/annum cost of fragility fractures • Peripheral fractures • Hip fractures • 70,000/annum • Expensive to treat • Expensive for patients and families • Money, morbidity, mortality and suffering • 20% die within 90 days • 50% survivors do not regain mobility • Psychological and social consequences • Disability • Admission to long term care • Loss of independence • Falling most common fear of older people • More common than fear of crime or financial fear • Leads to activity restriction, medication use

Oliver et al BMJ 2006 Falls: 0.82 (0.68 to 0.997) Fractures :0.59 (0.22 to 1.58) Relative risk for fallers: 0.95 (0.71 to 1.27) Included “poor quality” studies
Conclusions for hospitals • Multi-factorial fall prevention appear effective for patients >3 weeks LoS • No recommendation re: specific components of interventions • Exercise in subacute appears effective

Gates S, Lamb S, Fisher J, Cooke M, Carter Y. Multifactorial assessment and targeted intervention for preventing falls and injuries among older people in community and emergency care settings: systematic review and meta-analysis BMJ 2008 • “Evidence of benefit from multifactorial risk assessment and targeted interventions … was limited and reductions in the number of fallers may be smaller than thought.”

Interventions: Cochrane review 2009 • Exercise targets strength, balance, flexibility, endurance • programmes with 2 or more components reduce falls & fallers • Supervised group exercise, Tai Chi, & individual prescribed at home can be effective • Multifactorial assessment and referral works under certain circumstances • complex interventions causal mechanisms need clarification • Appropriate medication review and withdrawal can reduce falls • Environment • Home safety only effective for high risk- professionally administered • VIP • Surgery in appropriate clinical populations can reduce falls • Cataract surgery, pacemakers (carotid sinus hypersensitivity) • Vitamin D does not reduce falls (except in low baseline) (?)

WP4: Psychological aspects of falling • Motivation for prevention • Consequences • fear of falling (efficacy) • FES-I • fear of falling interventions
High refusal 50% common Low adherence 18% dropout average (15 weeks) 44% dropout Long term adherence poor Refusal and non-adherence 50% - 90% thus prevention may not be effective The Problem of Interest: Refusal, drop out & adherence
Prevention programmes are efficacious • Refusal/non-adherence 50% - 90% thus prevention may not be effective • Training needs to be challenging, progressive and done regularly.

Findings Perceptions of available falls prevention advice • Reported none received! • though actually mention of receiving information) • Perceived falls prevention in terms of hazard reduction • rather than balance improvement • often through restriction of activity
Perceptions of falls prevention messages presented Discussion of falling prevention is beneficial I think it would be helpful if someone knows what you should do and what you shouldn’t do.. I think it would give me more confidence of building up your balance if I read this [leaflet about improving balance] now. I think it would give me more confidence when I’m out.. (members of focusgroup of women aged 78 to 95 living in sheltered accommodation)
Perceptions of falls prevention messages presented cont. It’s good advice BUT - they wouldn’t necessarily act on (all of) it It’s all good. I mean its good advice, yes, excellent, I agree. I doesn’t mean to say I do it all but I agree. - it may not fit with their circumstances, lifestyle, prioritised goals No, no, no, no, no, no ... Nobody would go around with padding.
Perceptions of falls prevention messages presented cont. It’s good advice - for ‘them’ • only seen as relevant to ‘elderly’ Because we’re that much fitter -- we don’t really take too much notice of it, only for other people, for other disabled or elderly people that we have to watch when we’re – we always watch older people anyway. (man aged 79 in sheltered accommodation) - rejected by fit, younger people, seen as humiliating I wouldn’t go for that [advice] because it didn’t apply to me in any shape or form. Is there a bit of pride, is there a bit of “Well, you know, I’m not there yet” (fit woman in 60s)
Perceptions of falls prevention messages presented cont. Falls prevention advice unnecessary, upsetting It can make you feel – somebody producing the leaflets here – that these people here are senile and they just don’t have any common sense and they need to be told everything. The last thing you want as you get older is to be told that you’ve got to be conscious every time you go out and might fall, you don’t want that, otherwise your life’s gone. (woman 78, who had recently fallen)
Suggestions for future advice • Incorporate falls prevention into lifestyle and general exercise programmes, • Promote activities as • enjoyable • interesting, • sociable • Give suggestions in constructive manner • Give explanations • Recognise • individual’s knowledge • choice of own lifestyle
Quantitative test of conclusions from qualitative studies 558 people aged 60-95 71% women, mean 74.4 yrs 53% fell in past year 23% repeat fallers 1918 people aged 54+ (subgroup of 5396 surveyed) 57% women Mean 69.7 47% fell in past year 22% repeat fallers
Intention to carry out Strength & Balance Training .87 .09 Threat appraisal Coping appraisal Fear of falling (FES-I) Expected benefits of SBT Perceived vulnerability - risk of falling Expected attitudes of others Perceived severity -consequences of falling Expected ability to carry out SBT Perceived causes of falling Identity right to do SBT
Conclusions • Abandon efforts at ‘falls prevention’ -emphasise positive benefits of exercise • Emphasise positive benefits of measures, phrase advice to allow recipients to select/modify to suit goals and lifestyle • Target advice to different groups of older people (e.g. high/low perceived/actual risk)
Implications for practice Do not present initially to older people in terms of falling prevention (since falling risk denied anyway) Talk in terms of Activity Emphasise/maximise immediate wider Benefits: looking and feeling good; remaining active and independent; taking part in an enjoyable and interesting Communal/social activity Most effective approach is personal invitation from health professional explaining exactly what is involved, benefits. Illness, evidence of increasing Disability provides good opportunity to suggest taking this up. Exercise in terms of everyday activities “F” word Groups only for some Home based exercise preferred
