Strategy Identify a clinical lead Estimate total population of post-menopausal women Estimate prevalent and incident population with fragility fracture Estimate proportion eligible for secondary prevention according
to NICE TA 161 Estimate proportion likely to be eligible for treatment with
denosumab according to NICE TA 204 Involve Trust pharmacists Encourage the PCT and the Acute Trust to get a shared care

Assumptions
The numbers eligible for primary prevention with denosumab according to NICE TA 204 are theoretically very few

When to use denosumab (TA 204)
In secondary prevention– When bisphosphonates contra-indicated– When intolerance or failure of persistence– Cognitive impairment– When eGFR <35
In primary prevention– With the above and – With a combination age,
CRFs for # (parental history of hip #, alcohol >4 and RA) and BMD
Age 0 1 2
65–69 N/R −4.5 −4.0
70–74 −4.5 −4.0 −3.5
75 + −4.0 −4.0 −3.0
No. independent clinical risk factors for fracture

Assumptions
The numbers eligible for primary prevention with denosumab according to NICE TA 204 are theoretically very few
Since January it became an issue for the PCT NICE implementation team not the Formulary committee
First dose given in or authorised by specialist services 25% substitution rate if failure with or contra-indication
to alendronate/bisphosphonates 1
Estimates of the ‘worst case scenario’ were required

Baseline needs assessment data: where to look? Population (PCT, local government, DoPH report) ONS (http://www.statistics.gov.uk/hub/population/index.html)
– Female– 50-64, 65-74 and 75 plus
Local audit or NICE implementation monitoring data
FLS reports or DES activity analysis Hip fracture admission rate

Calculations
16% of the over 50 year old women are estimated to have a fragility fracture1,2
NICE has estimated that 50% of fractures occur in over 75 years, 25% in 65-74 year olds and 25% in 50-64 year olds
1,100/45,000 (2.44%) of over 65 year old population (including men) will sustain a fracture each year 2
This figure can be adjusted to exclude men (2:5) ratio and include under 65 eligible women (25%:75% ratio)
Of all women with a fragility fracture– 50% are over 75 years and all eligible for Rx– 25% 65-74 years and 50% eligible for Rx 2, 3
– 25% 50-64 years and 25% eligible for Rx 3

In Gloucestershire (pop 600,000) 1238 new fractures in over 50 year old women eligible for
treatment under TA161 each year At a 25% denosumab treatment rate that would equate to 309
new prescriptions/year £113,000, roughly equivalent to the calculated first year health
and social care costs of four hip fracture patients entering RNCH in 2002
3,183 prior fragility fracture eligible for treatment under TA161 patients at a cost of £1.175m
Equivalent to an English cohort of just over 1m women over 50 with a fragility fracture and osteoporosis

Calculations based on NICE TA 160/161 costing template
NICE calculates 1,030,928 women in England (base population 50,542,505) with osteoporosis and a fragility fracture
Women aged 50–54 years 2.00% 30,928 Women aged 55–59 years 3.00% 49,553 Women aged 60–64 years 7.00% 96,347 Women aged 65–69 years 9.00% 103,999 Women aged 70–74 years 14.00% 144,834 Women aged 75–79 years 20.00% 184,720 Women aged 80–84 years 26.00% 193,920
Women aged 85 years or older 31.00% 226,627
Total cases of osteoporosis with a clinically apparent osteoporotic
fragility fracture

Further information for commissioners
Trusts served by an FLS will have a higher case-identification rate of incident fractures
Nationally it is estimated 40-60% of women with prevalent fragility fracture are identified on GP databases 1

Further information for commissioners
Trusts served by an FLS will have a higher case-identification rate of incident fractures
Nationally it is estimated 40-60% of women with prevalent fragility fracture are identified on GP databases 1
As few as 25% of over 75 year old women may currently be treated and 10-20% of 65-74s may have evidence of DXA or treatment 1,2
If QOF 2013 includes indicators for delivering NICE TA 161/204 a higher proportion of eligible patients will be initiated on treatment
