OBJECTIVES: Despite an estimated 2 million osteoporosis (OP)-related fractures occurring annually, achievement of post-fracture OP quality measures is low. In 2013, the national average pass rate on the Healthcare Effectiveness Data and Information Set (HEDIS) measure “Osteoporosis Management in Women who had a Fracture” was 23%. This study has sought to identify characteristics associated with success or failure in meeting the current OP HEDIS measure. METHODS: Women were included if they were between 67-85 years (yrs) of age, had ≥1 fracture from July 2011 to December 2013 (index date = earliest encounter), and were continuously enrolled in a Humana Medicare Advantage with Prescription Drug coverage (MAPD) plan for at least 12 months pre-index and 6 months post-index. Patients were excluded if they had a BMD (bone mineral density) test or OP treatment pre-index. Descriptive statistics were compiled for the following variables: age, race, geographic region, and insurance type. RESULTS: The sample included 52,864 women. Mean age among the 17,952 (34%) patients who “passed” and the 34,912 (66%) who “failed” the HEDIS measure was 76.3 yrs and 76.1 yrs respectively (p=0.0003). A higher percentage of black women were in the “failed” group (6.2% failed vs. 5.4% passed; p<0.0001), while Hispanic women were more prevalent in the “passed” group (3.0% passed vs. 1.3% failed; p<0.0001). A larger proportion of patients residing in the Midwest were in the “failed” group (27.3% failed vs. 19.3% passed; p<0.0001), along with those in suburban (26.5% failed vs. 19.6% passed; p<0.0001) and rural (12.5% failed vs. 7.8% passed; p<0.0001) areas. A greater fraction of women who “passed” the measure (69.9% passed vs. 60.6% failed; p<0.0001) resided in the South. CONCLUSIONS: Preliminary results identify characteristics of women with OP who are receiving suboptimal care. Further analyses could enable targeting of at-risk women to improve post-fracture OP management.
