A new, user-friendly platform for the freely available online FRAX® calculator now hosts the beta version of FRAXplus®, an optional extra that illustrates how fragility fracture risk probabilities can be modified for recency of prior fracture, exposure to higher dose oral glucocorticoids, duration of Type 2 diabetes mellitus, Trabecular Bone Score (TBS), recent falls history, concurrent data on lumbar spine BMD and Hip axis length.
FRAX® is the most widely used online fracture risk assessment tool to estimate the individualized probability of hip fracture and major osteoporotic fracture. It integrates well-validated risk factors for fragility fracture with or without the use of bone mineral density, calibrated according to the country-specific epidemiology of hip fracture and mortality. FRAX® is available for 75 countries or territories and in 35 languages, covering more than 80% of the world’s population. It is incorporated into approximately 80 osteoporosis management guidelines worldwide.
Professor Eugene McCloskey MD, Professor of Adult Bone Diseases, Department of Oncology and Metabolism, University of Sheffield Medical School, UK, and co-developer of FRAX® stated:
“Notwithstanding FRAX’s unique strengths as confirmed in multiple studies since its launch in 2008, we have received many requests to refine or add further detail on fracture risk arising from existing FRAX variables and additional risk factors. The launch of a new and more user-friendly FRAX platform has given us the opportunity to introduce FRAXplus® which now gives clinicians the opportunity to explore the impact of this additional information for individual patients with specific risk factors.”
The following adjustments are currently available on FRAXplus®:
Professor McCloskey added:
“Clinicians using FRAXplus® (beta version) should note that, as there is no evidence base available to inform on the accuracy of multiple adjustments, a pragmatic approach is to make any adjustment for the most dominant factor, i.e., that which is likely to have the greatest clinical relevance for the estimated probability.”
In addition to FRAX score adjustments, FRAXplus® offers many helpful features that are accessible via 'My FRAX': User data can be inserted and managed to save time for future use; results, scores and variables are saved in the user's personal account for further use and to easily access a history of activities and results; results can be easily exported in a pdf file to facilitate sharing and to avoid any loss of data; results can be easily shared by email; and automatic synchronisation between various devices such as cell phones, tablets and computers is possible. While the online FRAX® calculator remains freely accessible, credits must be purchased in order to use FRAXplus®, with proceeds assigned to support the further development of the FRAX® tool. Free credits are offered when creating a new account and reduced rates are applicable for low and lower-middle income economies according to the World Bank Country Classification.
Professor John Kanis, Honorary President of the International Osteoporosis Foundation (IOF) and co-developer of FRAX®, noted:
“FRAX has been shown to be a robust assessment tool with extensive uptake in national and international guidelines. Indeed, it is now established as the standard global tool for fragility fracture risk assessment, accessible by countless healthcare professionals around the world to use in their clinical practice. With the availability of the beta version of FRAXplus® we offer clinicians the possibility to further refine risk prediction and to optimize the identification of those at highest fracture risk. It is so important that these high-risk patients go on to receive appropriate therapy to reduce their risk of suffering debilitating fragility fractures in the future.”

About FRAX®
FRAX® is a simple calculation tool that integrates clinical information in a quantitative manner to predict a 10-year probability of major osteoporotic fracture for both women and men in different countries. The tool was developed at the Centre for Metabolic Bone Diseases, University of Sheffield, UK in collaboration with international researchers. It assists primary health-care providers to better target people in need of interventions to reduce fracture risk, thus improving the allocation of health-care resources towards patients most likely to benefit from treatment. The FRAX calculator, freely accessible for use online, is available for 75 countries and in 35 languages. It is the most widely used risk assessment tool, incorporated into more than 80 national and regional guidelines worldwide.
