Background - Osteoporosis
Progressive skeletal disease characterised by low bone mass micro-architectural deterioration
Resulting in ↑ bone fragility ↑ susceptibility to fracture

2 types of osteoporosis
1. Involutional / senile ↓ cortical & trabecular bone
2. Post-menopausal & steroid-induced ↓ trabecular bone mainly

Fracture burden
>50y presenting with fragility # have a ↑ incidence of osteoporosis
Fragility # = fracture from standing height / less– These patients are readily identifiable & should be prioritised for treatment
Osteoporotic # affects 1:2 women and 1:5 men >50y – 1/3 of adult women will sustain >1 osteoporotic # in their lifetime– Patients with previous # are x 2 - 8 more likely to have a # at any skeletal site– 1/3 have a hip # by age of 80y
Hip fracture patients– 50% no longer able to live independently – 20% die within 6 months – 25 % require long term care
5y mortality after hip / vertebral # is 20% greater than expected
Cost– 200,000 fractures each year – £1 – 1.9 billion

Targeting therapy
It is possible to target 3 groups – though there is often much overlap
1. at risk of osteoporosis
2. at risk of falling
3. at risk of fragility fractures

Objectives
To ensure that all geriatric patients – with a history of falls – are on bone protective agents – in the form of Calcium & Vitamin D – to reduce the incidence of future osteoporotic
fragility fractures
![Page 16: Supplements in falls patients Dr Nick John Deepak Jadon (SHO) Older People’s Unit October 2007.](https://reader030.fdocuments.net/reader030/viewer/2022012910/56649d035503460f949d6f53/html5/thumbnails/16.jpg)
Methodology
Retrospective audit Patients admitted to Victoria Ward 6 months (1st February - 31st July 2007) Admitted under Acute Geriatric intake via
A&E MAU
Analysis of discharge summaries Case notes if more elaboration needed
![Page 17: Supplements in falls patients Dr Nick John Deepak Jadon (SHO) Older People’s Unit October 2007.](https://reader030.fdocuments.net/reader030/viewer/2022012910/56649d035503460f949d6f53/html5/thumbnails/17.jpg)
Methodology – Key parameters

Conclusion
93% compliance with guidelines is excellent ! But always room for improvement
We are excellent at targeting incident fallers– As it jogs our memory
Need to keep this issue at forefront of mind in those presenting with other complaints
– Asking ‘Have you ever had a fall before?’ takes a few secs

Suggested recommendations
↑ awareness amongst allied health professionals Implementation of ‘Falls Passport’
“All older people presenting with an injurious fall should be offered a multifactorial risk assessment” - NICE guidance 2005 -
– Currently used in ED– Assesses
Hx of falls Preciptating factors Exacerbating factors Vulnerability
– Triages further referral & investigation– Formally documents this assessment
Re-audit in 1year

NICE committee recommendations
Elderly population can’t be assumed to have an adequate dietary intake of calcium & vit D
Normal serum concentrations of calcium & vitamin D are needed to ensure optimum effects of the treatments for osteoporosis
Thus calcium + vitamin D prescribed unless clinicians are confident that levels are normal
![Page 33: Supplements in falls patients Dr Nick John Deepak Jadon (SHO) Older People’s Unit October 2007.](https://reader030.fdocuments.net/reader030/viewer/2022012910/56649d035503460f949d6f53/html5/thumbnails/33.jpg)
Evidence for Calcium & Vit D supplementation
Reviewed in the 2001 RCP Osteoporosis Guidelines Guidelines unclear if the benefits of Tx due to
– vitamin D– calcium – combination of both
Calcium 1g/day – ↓ bone loss in women with osteoporosis (level Ia)– ↓ the risk of vertebral fracture (leveI Ib)– effects on hip fracture are less certain (Level II)
Vitamin D 800 iu/day– ↓ hip & other # in the institutionalised frail elderly (level Ib)– beneficial effects in the general community have not been demonstrated.
Vitamin D & calcium in elderly female patients – saves great resources & low marginal costs– is recommended that these individuals be offered such treatment (grade A)

Dietary Sources
![Page 39: Supplements in falls patients Dr Nick John Deepak Jadon (SHO) Older People’s Unit October 2007.](https://reader030.fdocuments.net/reader030/viewer/2022012910/56649d035503460f949d6f53/html5/thumbnails/39.jpg)
Dietary Calcium
Intake of calcium is essential – throughout life – childhood & adolescence when bone most actively formed
Groups where calcium intake may be ↓– Adolescents
Skeletal length & density changes considerably Dieting teenage girls
– Sports people ↓ calcium intake is well documented among
– women athletes – sports where weight is important eg. jockeys, rowers, boxers, ballet dancers, gymnasts etc
– Vegans Soya milk (fortified with calcium & B12) good alternative to cows milk
– Malabsorption IBD, coeliacs & lactose intolerants = reduction in nutrient intake / calcium absorption

Dietary Vit D
Consider supplementation of vitamin D Older people
– Ageing ↓ the permeability of skin to sunlight, ↑the reliance on foods– Supplements are particularly recommended if
ill housebound resident in institution
Care Home. – WARNING: fish oil supplements are a rich source of vit D – avoid overdose
Pureed diets Ethnic attire
– Sunlight is the most important source of vitamin D. – In UK, sunlight most effective between approximately the April – Oct

Predictors of Vit D deficiency
A British study of 467 patients In 129 patients with hypovitaminosis D
– normal ALP 76%, – normal calcium 90%– normal phosphate 95%
In the 50 patients with the most severe hypovitaminosis D– 66% vegetarian / vegan– 72% clothing partially / completely occlusive of sunlight – 60% went outdoors < 5 times / week
Conclusion routine measurement of ALP, calcium & phosphate
– is of no use in predicting hypovitaminosis D risk factors for vitamin D deficiency
– Good predictors of hypovitaminosis D[ASSESSMENT OF VITAMIN D DEFICIENCY: USEFULNESS OF RISK FACTORS, SYMPTOMS AND ROUTINE BIOCHEMICAL TESTS GR Smith1, PO Collinson2, PDW Kiely]

Reducing the impact of falls
Using external hip protectors incorporated into specially designed underwear

Result– 50% reduction in hip # in hip protectors group. – Problems
