Objectives: To examine the fracture-related cost burden and healthcareresource utilization among post-menopausal women in the U.S. Medicare population. Methods: Post-menopausal women were identified using InternationalClassification of Diseases, 9th Revision, Clinical Modification (ICD-9-CM) diagnosiscodes from the U.S. Medicare claims dataset from 01JAN2008 through 31DEC2012.The first fracture diagnosis date was designated as the index date. One year ofcontinuous health plan enrollment was required for all patients pre- and postindex date. A comparison group was created, identifying patients without fracturesof the same age, region, gender and index year and were matched to case patientsbased on baseline Charlson Comorbidity Index scores. A randomly chosen indexdate for the comparison group reduced selection bias. Healthcare costs and utilizations were compared using 1:1 propensity score matching (PSM). Results: Beforematching (n=182,124), patients with fractures were more likely to be white (92.6%vs. 85.8%), reside in the Northeast U.S. region (19.4% vs. 16.4%), and have diagnosis of depression (18.0% vs. 13.0%) and chronic obstructive pulmonary disease(26.3% vs. 23.3%). After 1:1 PSM, 65,549 patients were included in each cohort andbaseline characteristics were well-balanced. Significantly more post-menopausalwomen with fractures had inpatient admission (42.3% vs. 8.6%, p<0.0001), outpatient (80.3% vs. 48.7%, p<0.0001), home health agency (31.2% vs. 6.9%, p<0.0001)skilled nursing facility (SNF) (25.7% vs. 2.72%, p<0.0001) and hospice admission(1.4% vs. 1.0%, p<0.0001) claims. Higher healthcare resource utilization translated to higher costs for post-menopausal fracture patients, including inpatient($7,869 vs. $1,203, p<0.0001), outpatient ($1,928 vs. $622, p<0.0001), SNF ($5,980vs. $437, p<0.0001), hospice ($338 vs. $244, p<0.0001), pharmacy ($1,052 vs. $829,p<0.0001) and total costs ($23,097 vs. $5,247, p<0.0001), than for those in the comparison cohort. Conclusions: Post-menopausal women with fractures in theU.S. Medicare population had higher healthcare resource utilization and expenditures than those without fractures.
