EXPERT PANEL KEY ASSUMPTIONS ON OSTEOPOROSIS FRACTURE ATTRIBUTION USING ADMINISTRATIVE CLAIMS DATA AND CLINICAL RISK FACTORS

Some fractures are caused by severe trauma but not identified or otherwise excluded; thus, certain fractures were rated as less likely due to osteoporosis. The absolute fracture incidence rate (i.e. the number of fractures that occur at each fracture site in the various risk groups) had minimal influence on the determination of whether a fracture that had occurred was likely due to osteoporosis. Phalanges were considered separate from carpal and tarsal bones. Potential errors in fracture coding and classification at each fracture site were considered.
