Prescreening tools to determine who needs DXA

Area of Science:

• Osteoporosis research
• Clinical decision support systems
• Women's health

Background:

• Clinical decision rules (CDRs) aim to improve physician practice.
• Several CDRs for identifying low bone mass in women have emerged since the mid-1990s.
• Examples include SCORE, OST (OSTA), OSIRIS, SOFSURF, NOF, ABONE, pBW, ORAI, and weight-only-EPIDOS (WO-E).

Purpose of the Study:

• To review and compare existing CDRs for low bone mass identification.
• To analyze the development and validation cohorts of these CDRs.
• To evaluate the sensitivity and specificity of the available CDRs.

Main Methods:

• Review of literature on CDRs for low bone mass.
• Analysis of development and validation data for each CDR.
• Comparison of sensitivity and specificity metrics.

Main Results:

• All reviewed CDRs demonstrate sensitivities exceeding 80%.
• Specificities for these CDRs are approximately 50%.
• OST is favored for simplicity, SCORE for flexibility, but consensus is lacking on risk factors and DXA regions.

Conclusions:

• A lack of consensus on risk factors and testing regions presents barriers to clinical application of CDRs.
• Widespread adoption requires agreement on a single, globally applicable CDR.
• Standardization is crucial for effectively identifying low bone mass and improving patient care.
