Web-based tool to predict risk of bone fracture
It will soon be possible for anyone over 60 to predict their
individual risk of bone fracture with the aid of a simple web-based
tool, developed by the Sydney-based Garvan Institute of Medical
Research.
The tool will be accessible online from the end of March at www.fractureriskcalculator.com
Each person has a unique risk profile, a combination of five factors
including sex, age, weight, history of prior fracture, number of falls
in the past 12 months and bone mineral density.
Scientists from Garvan developed the tool using data, accumulated over
17 years, from the internationally recognised Dubbo Osteoporosis
Epidemiology Study. A paper describing the tool and its methodology was
published online today in the prestigious international journal,
Osteoporosis International.
"The biggest challenge at the moment is how to develop prognostic tools
that allow individuals and their doctors to predict risk of fracture"
said Professor John Eisman, Director of Garvan's Bone and Mineral
Research Program.
Associate Professor Tuan Nguyen, whose team at Garvan developed the
tool, said "We have kept our model simple and easy to use. In addition
to the web-based version, it is also available on paper as a nomogram,
a simple graph which is easy for a clinician to complete."
The prognostic tool was developed in two stages. First, people from the
Dubbo epidemiological study were separated into 'low risk' and 'high
risk' categories. Their risk factors were combined in a statistical
model, allowing scientists to derive the weighting for each risk
factor. For these analyses, the Dubbo population was split into
two halves. Scientists derived the prognostic model from one half and
then applied the model to the other half to ensure that it accurately
predicted their fracture risk.
This Tool has the potential to allow individuals to make informed
judgments about their actual risk of having an osteoporotic fracture
and what steps they may wish to take to reduce that risk.
ABOUT GARVAN
The Garvan Institute of Medical Research was founded in 1963.
Initially a research department of St Vincent's Hospital in Sydney, it
is now one of Australia's largest medical research institutions with
approximately 400 scientists, students and support staff. Garvan's main
research programs are: Cancer, Diabetes & Obesity, Arthritis &
Immunology, Osteoporosis, and Neuroscience. The Garvan's mission is to
make significant contributions to medical science that will change the
directions of science and medicine and have major impacts on human
health. The outcome of Garvan's discoveries is the development of
better methods of diagnosis, treatment, and ultimately, prevention of
disease.
