A clinical decision support tool for accurate hip fracture prediction: A nationwide cohort study

Researchers used Swedish national registry data on 3.5 million adults aged 50+ to build a machine-learning model (FRACTURE-ML) that predicts hip fracture risk using only routinely collected data, no patient interview or exam needed. In a held-out validation cohort, the model achieved an AUC of 0.89 at 1 year and 0.85 at 5 years, and identified about seven times more at-risk people than the current fracture liaison service (secondary prevention) approach at 2 years (sensitivity 0.84 vs 0.12), with only a modest drop in specificity (0.79 vs 0.98).

Why it mattersOrthopedic surgeons and osteoporosis clinics may eventually use registry-based screening tools like this to identify at-risk patients earlier for fracture prevention, changing how referrals into osteoporosis/fall-prevention pathways are triggered.

• ?If a tool like FRACTURE-ML flagged many more patients as high-risk than current fracture liaison service criteria, how should orthopedic and primary care teams handle the resulting increase in referrals for DXA and osteoporosis workup?
• ?Given that the model has not been externally validated outside Sweden or tested in real clinical workflows, would you support using such a risk score to guide bone density testing or osteoporosis treatment decisions in your practice today?
