    tugal, despite the fact that this country has one of thelowest incidences of fragility fractures in Western Eu-rope1. The size of the problem will tend to increase re-lentlessly due to the increasing ageing of the populationand other societal changes5, unless effective preventivemeasures are put in place.

    This paper reports on the work of an Expert Com-mittee convened to foster such measures, by providingphysicians with practical and valid recommendationsregarding the initiation of pharmacological treatmentfor osteoporosis and/or the request of DXA evaluation,in order to optimize the efficiency of interventions andminimize the costs and risks for individuals and society.

    Since the last publication of recommendations forthe diagnosis and treatment of osteoporosis in Portugalin 20076, the FRAX tool has been incorporated in theclinical guidelines for OP of several countries5,7-12. Infact, over half of the subjects who experience a fragili-ty fracture do not have OP as defined by BMD13. FRAX

    integrates a set of well-proven clinical risk facto rs forfracture, independent of BMD: age, gender, body mass

    IntroductIon

    Osteoporosis (OP) is a metabolic skeletal disease cha -racterized by low bone mass and microarchitecture de-terioration leading to increased bone fragility and sus-ceptibility to fracture. In Portugal, the annual hipfragility fracture incidence is estimated to be between154 to 572 per 100.000 women and 77 to 232 per100.000 men, depending on age1. More than 10.000patients are admitted every year to the Portuguese Na-tional Health Service due to hip fragility fractures, jus-tifying annual total health care expenditures of over220 million euro2. This corresponded to 1.4% of the to-tal national health care expenditure in 2013, includingprivate and public services, according to PortugueseHealth Statistics3. The total expense with fragility frac-tures is much higher, as hip fractures only account forabout 39.1% of the total number of fragility fracturesobserved in Portugal according to a recent study4.

    Altogether, osteoporotic fractures currently repre-sent an enormous social and economic burden in Por-

    Portuguese recommendations on dXa request and Prevention of fragility fractures

    index, prior fragility fracture, parental history of hipfracture, long-term use of oral glucocorticoids,rheumatoid arthritis and other secondary causes of os-teoporosis, current smoking and alcohol intake, withor without BMD. It provides an estimate of the risk ofmajor osteoporotic fracture (hip, clinical spine,humerus or wrist fracture) and of hip fracture in thesubsequent 10 years14,15. FRAX provides valid pre-dictions without BMD values16,17, although its accura-cy increases when BMD is also considered18. This al-gorithm is applied upon the fracture epidemiology anddeath rates of each country, to provide locally opti-mized estimates of fracture probability. The FRAX wasderived from population-based cohort studies from Europe, North America, Asia and Australia andhas been validated in 62 countries and adopted by many as the key basis for decisions on whom totreat.

    With this in mind, we have recently validated theFRAX model for the estimation of osteoporotic frac-ture probability in the portuguese population FRAXPort15 (http://www.shef.ac.uk/FRAX/tool.aspx?country=53). Through systematic literature review andmeta-analysis19, as well as consensus discussion wehave decided that FRAX is the most appropriate ins -tru ment to achieve similar purposes in Portugal.Among its advantages lies the possibility of using iteven in the absence of BMD, allowing its output to de-cide if and when DXA is needed.

    We have also performed a nation-wide carefulevalua tion of the costs of hip fractures and their impactupon quality of life and mortality2. The fracture riskprobabilities above which the different interventionsbecome cost-effective, in the actual Portuguese settings, were defined based on matured economicmethodology, assisted by internationally renowned ex-perts2.

    These developments laid the optimal ground for atimely review of the Portuguese recommendations re-garding the risk threshold for DXA investigation andpharmacological treatment of osteoporosis.

    On these bases, we now recommend that decisionsregarding the performance of dual X-ray absorptiome -try (DXA) or the initiation of treatment are based on es-timates of the actual risk of fracture and the econo micimplications of fractures and the different preventivestrategies.

    This report does not cover all possible managementoptions and is not intended to override the indivi dualphysicians responsibility towards the patient or the

    personal choice of each patient. The authors wish toemphasize that formal guidance for every specific si -tuation or co-morbidity cannot be provided due to lackof appropriate evidence. Judicious clinical judgment isrequired in such conditions.

    This work, as well the series of supporting studiesalready published or under publication, have beenfun ded by the Portuguese Government through theDireco Geral da Sade DGS (Portuguese HealthDirectorate) following a proposal presented byAssocia o Nacional Contra a Osteoporose APOROS(Na tional Association Against Osteoporosis) and by anunrestricted grant from Amgen. None of the financialproviders had any involvement in the design of thestudies, interpretation of their results or the content ofderived reports and recommendations.

    A total of 10 recommendations were produced(Table I).

    Methods

    developMent of guIdelInes

    A number of national experts on osteoporosis and allthe relevant Portuguese scientific societies were invi -ted and accepted to participate in the development ofthese recommendations: Rheumatology; Ortho paedicsand Traumatology; Endocrinology, Diabetes andMetabolism; Gynaecology; Internal Medicine; Physicaland Rehabilitation Medicine; Family Me dicine, Na-tional Observatory for Rheumatic Disea ses and Portu -guese Society for Osteoporosis and Metabo lic Bone Di -seases. The only national patient organization activein the field of osteoporosis, Associao PortuguesaContra a Osteoporose APOROS, also participated inthe Committee. Altogether, the Committee had 17 vo -ting members, all of whom are co-authors of this re-port.

    Relevant questions to be addressed by the recom-mendations were defined by consensus in a first roundof e-mail consultations upon a draft prepared by thePrincipal Investigator (JAPS) and the research fellow(AM). A thorough literature review was performed inorder to address each question (AM and JAPS) andmade available to the committee members prior to themeeting. The electronic search was performed inPubMed MEDLINE (2006- January 15th 2015). Thesearch strategies included the following medical des -criptors: Osteoporosis, Osteoporotic fractures,Risk Assessment, Algorithms, Recommendations,
