Abstract:
Little is known regarding osteoporosis management between Traditional Medicare (TM) and Medicare Advantage (MA). MA beneficiaries had higher rates of osteoporosis testing and higher rates of osteoporosis drug treatment initiation rates. Following an osteoporotic fragility fracture, MA beneficiaries were more likely to be prescribed osteoporosis treatment. While osteoporosis testing and treatment initiation rates are low in both TM and MA, rates tended to be higher in MA.
Purpose:
Osteoporosis represents a substantial clinical challenge in the United States, particularly for older women, and requires effective care coordination. Medicare Advantage (MA) plans have financial incentives in the form of star ratings to improve osteoporosis testing and treatment. The objective of this study was to compare osteoporosis management practices between Traditional Medicare (TM) beneficiaries and MA female enrollees.
Methods:
We conducted a cross-sectional study using a nationally representative 20% sample of 2017-2019 TM claims and MA encounter records. We identified 2,994,203 female TM beneficiaries and 1,924,132 MA enrollees. The exposure was enrollment in MA. The primary outcomes were the rates of guideline-recommended bone mineral density (BMD) testing and osteoporosis drug initiation following a new osteoporosis diagnosis and after a new osteoporotic fragility fracture.
Results:
MA beneficiaries had higher unadjusted (22.0% vs. 19.8% in TM; P < 0.001) and adjusted rates (0.8 percentage points [p.p.] higher; P < 0.001) of BMD testing. Osteoporosis drug treatment initiation rates were higher in the MA cohort, both unadjusted (24.9% vs. 20.3% in TM; P < 0.001) and adjusted (4.0 p.p. higher; P < 0.001). Following an osteoporotic fragility fracture, MA beneficiaries were more likely to be prescribed pharmacologic treatment (28.7% vs. 21.1% in TM; P < 0.001), with an adjusted increase of 5.9 p.p (P < 0.001).
Conclusion:
Overall osteoporosis testing and treatment initiation rates in both TM and MA enrollees were low, with improved rates in MA compared to TM.

Bone deposition is also affected by the levels of sex hormones like estrogen and testosterone that promote osteoblast activity and bone matrix synthesis. When the level of these hormones decreases due to aging, it causes a reduction in bone deposition. As a result, bone resorption by osteoclasts...
