A Randomized Controlled Trial of a Bone Density Decision Aide

Osteoporosis

Osteoporosis, Fractures, Bone, Bone Mineral Density

This research study is being conducted to determine if a modified bone mineral density (BMD) test report that contains additional fracture risk information will be a useful physician decision aide in selecting patients for pharmacological osteoporosis therapy. It is hypothesized that this supplementary information, provided in addition to the conventional BMD report, will increase the likelihood that patients at high risk for an osteoporotic fracture will receive prescribed therapy for osteoporosis.

This observational research study is being conducted to determine if a modified bone mineral density (BMD) test report that contains additional fracture risk information will be a useful physician decision aide in selecting patients for pharmacological osteoporosis therapy. It is hypothesized that this supplementary information, provided in addition to the conventional BMD report, will increase the likelihood that patients at high risk for an osteoporotic fracture will receive prescribed therapy for osteoporosis. Physicians who only receive the conventional BMD reports without the supplemental information will be the control group. To compare the rates of pharmacological interventions for osteoporosis in post-menopausal women, family / primary care physicians are randomized to receive either:(i) a conventional BMD report (absolute bone density, T-score result, Z-score result, qualitative statement indicating the BMD results classification of risk for fracture from osteoporosis according to the World Health Organization (WHO) criteria) versus (ii) a conventional BMD report plus a supplemental information sheet (all the information contained in the conventional BMD report plus five-year estimated risks for future fractures calculated from the physician-supplied clinical risk factors and - for those who have osteoporosis according to the WHO criteria - the number needed to treat (in person years) to prevent one fracture.
