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.

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.

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.

But there Osteoporosis and Fracture Prevention Strategy is little evidence about their effect on fracture risk from randomised controlled trials.

Osteoporosis and Fracture Prevention Strategy 13 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.
The NHS provides an administrative frameworkwhereby general health screening for the identification Population-based preventive strategies are par ticularly of risk factors for falls and systematic inter vention well placed to reduce fall frequency by encouraging with a multi-dimensional series of components could regular weight-bearing physical activity among elderly easily be incorporated in primar y and secondar y care.

Multi-faceted inter ventions reduce falls in olderpeople and therefore fractures This strategy for the prevention of falls in those at Assessment and appropriate referral of high risk high risk of falling and fracturing is suppor ted by a prospective randomised controlled trial from theUnited States29.

Hip fracture data is available through the Patient American Geriatric Societies Guidelines31. The NOS Episode Database for Wales (PEDW) and the All Wales has examples of audit protocols which focus on Injur y Sur veillance System (AWISS). Currently wrist management of high-risk groups such as patients and ver tebral fractures are poorly recorded. LHBs may being prescribed oral glucocor ticosteroids, that can be wish to liaise with their local acute providers to identify used by LHBs to assess their per formance against what local data are available. Ver tebral fractures are commonly under-repor ted but this is in par t becauseonly approximately one-third come to clinical attention.
Benefits in fracture reduction may be seen within oneyear, par ticularly if inter ventions are aimed at thoseaged over 65.
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.
Identification of a lead clinician(s) for osteoporosis in secondar y care and a lead GP for the LHB GP time to par ticipate in local district-wide interest group, implement framework and monitor per formance: 1 GP session per week (£110 plus NI) plus travel expenses (absorbed within ongoing health promotion activity) Referral for hip and spine DXA (approximately 1,000 scans assuming a cost of £50) (The actual cost of DXA scans varies) Access to specialist exper tise on treatment for established osteoporosis 1 par t-time osteoporosis nurse to assist with case finding 16,000 Prescribing costs (500 patients @ average drug cost of £170 per patient with 4 GP consultations per year) This ser vice would cost the same as managing 9 out of the 145 hip fractures which occur in a population of100,000 per year39 (see Table 2 on page 9).

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.

Segregation according to household size in a monocentric city by Theis Theisen Abstract Over the last two centuries, household size has decreased considerably. Within a theoretical model I investigate the relationship between household size and the structure and size of cities. Household utility is assumed to depend on household size, in addition to the consumption of housing and a numerai
