Common fracture risk predictors often fail for women of any race

“This evidence supports using OST instead of FRAX” for selecting younger postmenopausal women who should undergo a bone mineral density exam, said E. Michael Lewiecki, MD, director of the New Mexico Clinical Research & Osteoporosis Center in Albuquerque.

Dr. Lewiecki, who was not involved in the new study, noted that the U.S. version of FRAX specifies race because of some clinical evidence that different races have different rates of fracture. But he and Dr. Crandall said the validity of race-based algorithms to guide clinical care is a controversial and evolving topic in medicine. Dr. Lewiecki said the Canadian version of FRAX, which is similarly applied to a diverse population as in the United States, omits race and works as well as the U.S. version. Future iterations of the instrument in the United States may not include race, Dr. Lewiecki said.

“The study is perfectly valid as far as it goes. But the big gorilla in the room is that most patients who need a bone density test are not getting it,” Dr. Lewiecki added. Sometimes a patient might break a bone in their wrist, for example, and tell their primary care provider that anyone would have broken that bone because the fall was so hard. Even if that’s true, Dr. Lewiecki said, any woman older than 45 who has broken a bone should undergo a bone density test to determine if they have osteoporosis, even if it seems like there are other possible reasons for why the break occurred.

“Most of the clinical practice guidelines that are used by physicians recommend getting a bone density test in postmenopausal women under the age of 65 who have a risk factor for fracture,” Dr. Lewiecki said, with a primary risk factor being a prior fracture. Dr. Lewiecki said he would rather that anyone who could benefit from a bone density test receive it, rather than someone foregoing a scan based on a screening tool that may be flawed.

“Most patients – men and women – who have osteoporosis are currently not being identified. Even when they are being identified, they are commonly not being treated. And when they are started on treatment, many patients discontinue treatment before they’ve taken it long enough to benefit,” Dr. Lewiecki said.

Dr. Crandall and Dr. Lewiecki report no relevant financial relationships.
