BACKGROUND: Osteoporosis is prevalent in the United States, with an increasing need for management. In this study, we evaluated the effectiveness of a private orthopaedic practice-based osteoporosis management service (OP MS) in reducing subsequent fracture risk and improving other aspects of osteoporosis management of patients who had sustained fractures.
METHODS: This was a retrospective cohort study using the 100% Medicare data set for Michigan residents with any vertebral; hip, pelvic or femoral; or other nonvertebral fracture during the period of April 1, 2010 to September 30, 2014. Patients who received OP MS care with a follow-up visit within 90 days of the first fracture, and those who did not seek OP MS care but had a physician visit within 90 days of the first fracture, were considered as exposed and unexposed, respectively (first follow-up visit = index date). Eligible patients with continuous enrollment in Medicare Parts A and B for the 90-day pre-index period were followed until the earliest of death, health-plan disenrollment, or study end (December 31, 2014) to evaluate rates of subsequent fracture, osteoporosis medication prescriptions filled, and bone mineral density (BMD) assessments. Health-care costs were evaluated among patients with 12 months of post-index continuous enrollment. Propensity-score matching was used to balance differences in baseline characteristics. Each exposed patient was matched to an unexposed patient within ± 0.01 units of the propensity score. After propensity-score matching, Cox regression examined the hazard ratio (HR) of clinical and economic outcomes in the exposed and unexposed cohorts.
RESULTS: Two well-matched cohorts of 1,304 patients each were produced. The exposed cohort had a longer median time to subsequent fracture (998 compared with 743 days; log-rank p = 0.001), a lower risk of subsequent fracture (HR = 0.8; 95% confidence interval [CI] = 0.7 to 0.9), and a higher likelihood of having osteoporosis medication prescriptions filled (HR = 1.7; 95% CI = 1.4 to 2.0) and BMD assessments (HR = 4.3; 95% CI = 3.7 to 5.0). The total 12-month costs ($25,306 compared with $22,896 [USD]; p = 0.082) did not differ significantly between the cohorts.
CONCLUSIONS: A private orthopaedic practice-based OP MS effectively reduced subsequent fracture risk, likely through coordinated and ongoing comprehensive patient care, without a significant overall higher cost.
