Abstract
Purpose: Describe fracture risk assessment practices among physicians treating osteoporosis in a real-life setting. Methods:This is a retrospective cohort study in a tertiary academic center. Inclusion criteria involved adults (aged ≥18 years) who received minimum adequate therapy (bisphosphates, raloxifene, or denosumab ≥ 3 years or teriparatide ≥ 18 months). Of 1,814 charts randomly selected and reviewed, 274 patients met the inclusion criteria.Risk stratification tools included fragility fractures, Dual-energy X-ray Absorptiometry (DXA), and fracture risk assessment using the FRAX tool. Fracture risk assessment was performed before therapy initiation (N= 274) and at the time of institution of the drug holiday (N=119). High-risk patients were defined as the presence of a fragility fracture, T-score ≤-2.5, or a high-risk score by FRAX calculation. FRAX scores were independently calculated by the research team for comparison and assessment purposes. Results: Before initiation of therapy (N=274) versus upon starting a drug holiday (DH; N=119), 29.9% versus 3.4% had a history of fragility fractures (P<0.001), 58.8% versus 67.2% had a DXA scan performed (P>0.05), 10.5% versus 10.9% of physicians calculated a FRAX score (P>0.05), and 71.5% versus 66.4% were considered at high risk and eligible for therapy. A DXA scan was performed after DH in 40.2% of these patients and at least once in 95.3% of the entire cohort. Conclusion: The reporting of FRAX score in DXA scan reports may significantly increase its utilization in fracture risk assessment. We recommend comprehensive fracture risk assessment utilizing history of prevalent osteoporosis fractures, DXA assessment, and FRAX scoring.
