PAPER 153: FACTORS INFLUENCING THE DIAGNOSIS AND THE TREATMENT OF OSTEOPOROSIS FOLLOWING A FRAGILITY FRACTURE

Purpose: Recognizing Osteoporosis and Its Consequences in Quebec revealed that 73% of women 50y and over are not provided anti-fracture therapy following fragility fracture. This study’s objectives were to determine predictors of osteoporosis (OP) diagnosis (DX) and treatment (TX) 6 to 8 months after fragility fracture. Method: At phase 1, women were recruited at cast or out-patient clinics within 16 weeks post-fracture. Consenting patients answered a short questionnaire classifying them as experiencing a fragility or traumatic fracture; no reference to the association between fracture and OP was made and no investigation or intervention was proposed. At phase 2, 6–8 months post-fracture, the women completed a questionnaire on demographic features, clinical characteristics and risk factors for OP. The DX (informed of OP and/or BMD measurement with diagnosis of OP) and TX (bisphosphonates, raloxifene, nasal calcitonin or teriparatide) rates of OP were determined via this questionnaire. This analysis included only women with a fragility fracture who were not receiving OP TX at phase 1. Results: Of the 1273 women completing phase 1, 1001 (79%) sustained a fragility fracture; 818 were untreated at phase 1 and completed the phase 2 questionnaire. Overall, 79% of these participants had not received a DX of osteoporosis or were without OP TX at phase 2. The highest rate of DX and TX of OP occurred 0–5 months post-fracture and decreased considerably thereafter. In multivariate analyses, the results of BMD tests before or after the fracture event (p Conclusion: Although fragility fracture represents a greater risk of future fragility fracture than low BMD, physicians based their decision to treat on BMD and not the clinical event (fragility fracture).
