Postmenopausal bone density referral decision rules: correlation with clinical fractures

Area of Science:

• Gerontology
• Osteoporosis Research
• Clinical Decision Support

Background:

• Postmenopausal osteoporosis is a significant health concern, increasing fracture risk.
• Accurate identification of at-risk individuals is crucial for timely intervention.
• Existing clinical decision rules (CDRs) aim to identify women needing bone mineral density (BMD) assessment.

Purpose of the Study:

• To evaluate the effectiveness of three established CDRs in predicting fracture history among postmenopausal women.
• To compare the performance of the Osteoporosis Risk Assessment Instrument (ORAI), Age, Body Size, No Estrogen (ABN), and weight-based criteria.

Main Methods:

• A cross-sectional study involving postmenopausal women from a military primary care clinic.
• Testing of three CDRs against self-reported fracture history.
• Analysis using relative risk (RR), area under the receiver operating characteristics curve (aROC), sensitivity, and specificity.

Main Results:

• The study included women with an average age of 69; 15% reported prior fractures.
• Caucasian women and those over 65 exhibited higher fracture prevalence.
• The ORAI demonstrated the highest aROC (0.65) and sensitivity (0.83), while the weight criterion was most specific (0.56).

Conclusions:

• Current BMD referral decision rules provide only a modest correlation with actual clinical fractures.
• The ORAI and ABN rules showed better predictive capabilities than the weight criterion.
• Refinement of existing CDRs or development of new tools is warranted for improved fracture risk stratification.
