Osteoporosis andFracture PreventionStrategy for Wales
A Primary Care Strategyfor Local Health Boards
National Osteoporosis
Produced by the National Osteoporosis SocietyJune 2003
“Osteoporosis is a ver y serious disease which results in 12,000 fractures in Waleseach year, causing severe pain and disability to individuals at a heavy cost to theWelsh Health Ser vice. But it is one of the few areas in which early inter vention topromote and maintain bone health can make a real impact on the burden of thedisease.
“I am delighted that the National Osteoporosis Society (NOS) has developed thisprimar y care strategy for osteoporosis and fracture prevention to help inform LocalHealth Boards (LHBs). The Society’s ‘cradle to grave’ strategy, involving manydifferent agencies, is an excellent example of the type of integrated approach thatis likely to be successful in the long-term.”
Professor Ruth HallChief Medical Officer
Message from the Minister for Health and Social Services
“This Osteoporosis and Fracture Prevention Strategy will assist and inform LocalHealth Boards (LHBs) working with the NHS trusts and social ser vices to addressthe rising tide of osteoporotic fractures in par ticular, reducing bed blockage. Thisapproach emphasises the prevention of osteoporotic fractures through thepromotion of a healthy active life and the prevention and treatment of osteoporosis. The NOS strategy uses an evidence-based approach and links to national priorities,making it a wonder ful example of joined-up thinking.
“By tackling osteoporosis, LHBs have a real oppor tunity to improve the health oftheir patients through adopting a systematic approach within multi-agency teams.”

Osteoporosis and Fracture Prevention Strategy 3
Executive summaryKey recommendations are summarised below:
Include prevention of osteoporotic fractures in the local Health Improvement Programme (HIP).
Equality of access for diagnosis and treatment of osteoporosis for the people of Wales.
Identify lead clinicians in primar y and secondar y care to develop an osteoporosis programme based on thisstrategy:
each Local Health Board (LHB) should have a lead GP for osteoporosis, responsible for monitoring theimplementation of this programme.
each acute Trust should have a lead consultant for osteoporosis, responsible for clinical referrals,super vision of diagnostic ser vices and liaison with primar y care.
Establish a local osteoporosis interest group to facilitate multi-disciplinar y implementation of this framework.
Use a selective case-finding approach to target the treatment of individuals at high risk of osteoporoticfracture. This includes individuals with a histor y of previous fracture, frequent falls, use of oralglucocor ticosteroids or other clinical risk factors.
Provide access to adequate levels of diagnostic and specialist ser vices; thus a LHB ser ving a population of100,000 would require approximately 1,000 hip and spine DXA scans per year.
Promote the use of care pathways and audits to improve standards of care.
Monitor per formance to assess health impact.
Limit prescribing costs by targeting treatment at those for whom it is really necessar y and by identifyingthose treatments inappropriately prescribed.
This strategic document sets clear standards to enable LHBs to offer a high quality osteoporosis ser vice. LHBsmay wish to adopt a stepwise approach to its implementation, identifying which of the high risk groups detailedon pages 15-19 require immediate, medium and long-term action, and targeting resources as appropriate.

Current annual expenditure incurred in managing fractures related to osteoporosis issummarised in Table 2.

# Of the 200 patients with x-ray evidence of ver tebral fractures 40 come to clinical attention and are costed.
The oppor tunity cost of not taking action to prevent fractures is clearly considerable. The cost of implementingthis ser vice strategy will var y according to local unit costs for diagnostic ser vices, professional educationrequirements, extent of generic prescribing and whether patient costs are included. An illustration is given onpage 23. From a societal perspective, fracture prevention will yield significant improvements in quality of life,such as the ability to maintain independent living. It will also reduce demand on social ser vices. In addition,reducing the cost of acute care for osteoporotic fractures will save scarce health care resources.

As with osteoporosis, strategies to reduce the frequency of falls in elderly peoplemay be aimed either at the entire population or at high risk individuals. Epidemiological studies have clearly identified important risk factors for falls inelderly people27. Intrinsic risk factors include problems with walking (reducedbalance, gait and muscle strength); use of multiple medications (particularly thoseleading to sedation and reduced blood pressure), and impairment of vision ormemory. Extrinsic factors include poor lighting, unsafe stairs, loose rugs, poorlyfitting footwear or clothing, and the lack of safety equipment. The reduction offalls should lead to a reduction in fractures.

Osteoporosis and Fracture Prevention Strategy
LHBs may wish to adopt a stepwise approach to the implementation of anosteoporosis strategy, identifying which of the high-risk groups require immediate,medium or long-term action, and targeting resources appropriately. Initially, as atemporary measure, LHBs may want to adopt a few of the steps below beforeproviding a full osteoporosis service.
The following indicates the annual cost that might be incurred in providing the ser vice framework forosteoporosis as outlined. It is viewed from the perspective of a LHB ser ving a population of 100,000 and willvar y according to local unit costs.

Osteoporosis and Fracture Prevention Strategy
Key recommendations are summarised below:
Include prevention of osteoporotic fractures in the local HIP
Identify lead clinicians in primar y and secondar y care to develop an osteoporosis program based on thisstrategy:
each Local Health Board (LHB) should have a lead GP for osteoporosis , responsible for monitoring theimplementation of this program.
each acute trust should have a lead consultant for osteoporosis, responsible for clinical referrals,super vision of diagnostic ser vices and liaison with primar y care.
Establish a local osteoporosis interest group to facilitate multi-disciplinar y implementation of this framework.
Use a selective case-finding approach to target the treatment of individuals at high risk of osteoporoticfracture. This includes individuals with a histor y of previous fracture, frequent falls or use of oralglucocor ticosteroids.
Provide access to adequate levels of diagnostic and specialist ser vices; thus a LHB ser ving a population of100,000 would require approximately 1,000 hip and spine DXA scans per year.
Promote the use of care pathways and audits to improve standards of care.
Monitor per formance to assess health impact.
Equality of access for diagnosis and treatment of osteoporosis for the people of Wales.
This strategic document sets clear standards to enable LHBs to offer a high quality osteoporosis. LHBs maywish to adopt a stepwise approach to its implementation, identifying which of the high risk groups detailed onpages 15-19 require immediate, medium and long-term action, and targeting resources as appropriate.
