Adherence and Persistence with Once-Daily Teriparatide in Japan: A Retrospective, Prescription Database, Cohort Study
Adherence and persistence with osteoporosis treatments are essential for reducing fracture risk. Once-daily teriparatide is available in Japan for treating osteoporosis in patients with a high risk of fracture. The study objective was to describe real-world adherence and persistence with once-daily teriparatide 20 μg during the first year of treatment for patients who started treatment during the first eight months of availability in Japan. This prescription database study involved patients with an index date (first claim) between October 2010 and May 2011, a preindex period ≥6 months, and a postindex period ≥12 months and who were aged >45 years. Adherence (medication possession ratio (MPR)) and persistence (time from the start of treatment to discontinuation; a 60-day gap in supply) were calculated. A total of 287 patients started treatment during the specified time period; 123 (42.9%) were eligible for inclusion. Overall mean (standard deviation) adherence was 0.702 (0.366), with 61.0% of patients having high adherence (MPR > 0.8). The percentage of patients remaining on treatment was 65.9% at 180 days and 61.0% at 365 days. Our findings suggest that real-world adherence and persistence with once-daily teriparatide in Japan are similar to that with once-daily teriparatide in other countries and with other osteoporosis medications
Interstate Variation in the Burden of Fragility Fractures
Demographic differences may produce interstate variation in the burden of osteoporosis. We estimated the burden of fragility fractures by race/ethnicity, age, sex, and service site across five diverse and populous states. State inpatient databases for 2000 were used to describe hospital fracture admissions, and a Markov decision model was used to estimate annual fracture incidence and cost for populations ≥50 yr of age for 2005–2025 in Arizona (AZ), California (CA), Florida (FL), Massachusetts (MA), and New York (NY). In 2000, mean hospital charges for incident fractures varied 1.7-fold across states. For hip fracture, mean charges ranged from 29,500 (CA), length of stay from 5.3 (AZ) to 8.9 days (NY), and discharge rate to long-term care from 43% (NY) to 71% (CA). In 2005, projected fracture incidence rates ranged from 199 (CA) to 266 (MA) per 10,000. Total cost ranged from 1,434 million (CA). Men accounted for 26–30% of costs. Across states, hip fractures constituted on average 77% of costs; “other” fractures (e.g., leg, arm), 10%; pelvic, 6%; vertebral, 5%; and wrist, 2%. By 2025, Hispanics are projected to represent 20% of fractures in AZ and CA and Asian/Other populations to represent 27% of fractures in NY. In conclusion, state initiatives to prevent fractures should include nonwhite populations and men, as well as white women, and should address fractures at all skeletal sites. Interstate variation in service utilization merits further evaluation to determine efficient and effective disease management strategies

Direct and Indirect Costs of Non-Vertebral Fracture Patients with Osteoporosis in the US
Background: Osteoporosis is a condition marked by low bone mineral density and the deterioration of bone tissue. One of the main clinical and economic consequences of osteoporosis is skeletal fractures. Objective: To assess the healthcare and work loss costs of US patients with non-vertebral (NV) osteoporotic fractures. Methods: Privately insured (aged 18-64 years) and Medicare (aged ≥65 years) patients with osteoporosis (ICD-9-CM code: 733.0x) were identified during 1999-2006 using two claims databases. Patients with an NV fracture (femur, pelvis, lower leg, upper arm, forearm, rib or hip) were matched randomly on age, sex, employment status and geographic region to controls with osteoporosis and no fractures. Patient characteristics and annual healthcare costs were assessed over the year following the index fracture for privately insured (n - 4764) and Medicare (n - 48 742) beneficiaries (Medicare drug costs were estimated using multivariable models). Indirect (i.e. work loss) costs were calculated for a subset of privately insured, employed patients with available disability data (n - 1148). All costs were reported in $US, year 2006 values. Results: In Medicare, mean incremental healthcare costs per NV fracture patient were $US13 387 ($US22 466 vs $US9079; p < 0.05). The most expensive patients had index fractures of the hip, multiple sites and femur (incremental costs of $US25 519, $US20 137 and $US19 403, respectively). Patients with NV non-hip (NVNH) fractures had incremental healthcare costs of $US7868 per patient ($US16 704 vs $US8836; p < 0.05). Aggregate annual incremental healthcare costs of NVNH patients in the Medicare research sample (n - 35 933) were $US282.7 million compared with $US204.1 million for hip fracture patients (n - 7997). Among the privately insured, mean incremental healthcare costs per NV fracture patient were $US5961 ($US11 636 vs $US5675; p < 0.05). The most expensive patients had index fractures of the hip, multiple sites and pelvis (incremental costs of $US13 801, $US9642 and $US8164, respectively). Annual incremental healthcare costs per NVNH patient were $US5381 ($US11 090 vs $US5709; p < 0.05). Aggregate annual incremental healthcare costs of NVNH patients in the privately insured sample (n - 4478) were $US24.1 million compared with $US3.5 million for hip fracture patients (n - 255). Mean incremental work loss costs per NV fracture employee were $US1956 ($US4349 vs $US2393; p < 0.05). Among patients with available disability data, work loss accounted for 29.5% of total costs per NV fracture employee. Conclusion: The cost burden of NV fracture patients to payers is substantial. Although hip fracture patients were more costly per patient in both Medicare and privately insured samples, NVNH fracture patients still had substantial incremental costs. Because NVNH patients accounted for a larger proportion of the fracture population, they were associated with greater aggregate incremental healthcare costs than hip fracture patients.Cost-of-illness, Fracture, treatment, Hip-fracture, treatment, Osteoporosis, treatment

FRAX and the effect of teriparatide on vertebral and non-vertebral fracture
Background: daily administration of 20µg or 40µg teriparatide has been shown to significantly decrease the risk of vertebral and non-vertebral fracture compared with placebo. The aim of the present study was to evaluate fracture risk assessed at baseline using the FRAX® tool and to determine the efficacy of teriparatide as a function of baseline fracture risk. Methods: 1637 postmenopausal women in the pivotal phase 3 trial, randomly assigned to receive placebo (n=544), teriparatide 20 ?g per day (n=541) or teriparatide 40 ?g per day (n=552), were studied. Baseline clinical risk factors were entered into country-specific FRAX models to compute the 10-year probability of major osteoporotic fractures with or without input of femoral neck BMD. Because there was no difference in effect of 20 and 40?g teriparatide daily on fracture occurrence, the two active groups were merged. The interaction between probability of a major fracture and treatment efficacy was examined by Poisson regression. Results: the 10-year probability of major osteoporotic fractures (with BMD) ranged from 2.2-67.2%. Treatment with teriparatide was associated with a 37% decrease in all non-vertebral fractures (95% CI:10-56 %) and a 56% decrease in low energy non-vertebral fractures (95% CI:24-75%) compared with placebo. The risk of morphometric vertebral fractures decreased significantly by 66% (95% CI:50-77%). Hazard ratios for the effect of teriparatide on the fracture outcome did not change significantly with increasing fracture probability (p>0.30). Similar findings were noted for the interaction when BMD was excluded from the FRAX model, or when probability of hip fracture was used as the marker of baseline risk. Conclusion: we conclude that teriparatide significantly decreases the risk of non-vertebral and morphometric vertebral fractures in women by a similar extent, irrespective of baseline fracture probability<br/

Overall mean (standard deviation) adherence was 0.702 (0.366), with 61.0% of patients having high adherence (MPR > 0.8). The percentage of patients remaining on treatment was 65.9% at 180 days and 61.0% at 365 days. Our findings suggest that real-world adherence and persistence with once-daily teriparatide in Japan are similar to that with once-daily teriparatide in other countries and with other osteoporosis medications
