Actual versus predicted first-year utilization patterns of teriparatide in patients with employer-sponsored health insurance.

OBJECTIVE: To characterize first-year utilization patterns of teriparatide derived from a claims database analysis versus predictions from an economic model. RESEARCH DESIGN AND METHODS: Claims data for actual teriparatide utilization were obtained from an integrated administrative database of approximately 3.4 million beneficiaries. A control group included patients with osteoporosis but without the use of teriparatide. An economic model, which relied on first-year market share projections, predicted the utilization of teriparatide from the demographic characteristics of the plan. Predictions were compared to actual utilization for eight health plans within the database. MAIN OUTCOME MEASURES: Demographic and clinical characteristics, number of teriparatide patients, and days of teriparatide therapy. RESULTS: Less than 1% of patients diagnosed with osteoporosis received teriparatide. Teriparatide-treated patients, compared to other patients with osteoporosis, were older and more likely to have experienced a previous fracture or to have received previous osteoporosis pharmacotherapy. For the combined 505 300 lives in the eight plans used for the comparative analysis, there were 134 teriparatide patients; the model predicted 131. For individual plans, the predictions varied in their accuracy. The greatest under-prediction for one plan was 17 patients (40 predicted vs. 57 actual), while the greatest over-prediction was 18 patients (34 predicted vs. 16 actual). For the other 6 plans, the predictions were within four patients of the actual number of teriparatide users. A similar pattern of differences was observed by comparing actual versus predicted days of teriparatide therapy across the eight plans. LIMITATIONS: Some clinical details of the actual patient cohorts, such as bone mineral density results, were not available in the database. The comparisons made between the teriparatide model predictions and actual utilization were based on analyses of a single model and do not speak to the broader issue of the accuracy of predictive economic models in general. CONCLUSIONS: Overall, first-year teriparatide utilization was relatively limited, consistent with model predictions. Predictions for individual plans varied in their accuracy.

The value of antihypertensive drugs: a perspective on medical innovation.

Using national survey data and risk equations from the Framingham Heart Study, we quantify the impact of antihypertensive therapy changes on blood pressures and the number and cost of heart attacks, strokes, and deaths. Antihypertensive therapy has had a major impact on health. Without it, 1999-2000 average blood pressures (at age 40+) would have been 10-13 percent higher, and 86,000 excess premature deaths from cardiovascular disease would have occurred in 2001. Treatment has generated a benefit-to-cost ratio of at least 6:1, but much more can be achieved. More effective use of antihypertensive medication would have an impact on mortality akin to eliminating all deaths from medical errors or accidents.

Assessing the economic impact of chronic conditions in postmenopausal women.

The ageing of the US population and the recognised importance of preventative care has led to a growing body of research regarding the morbidity and mortality associated with chronic diseases in postmenopausal women. According to the National Institute of Health, postmenopausal women have a significant increase in risk for a number of debilitating diseases, including osteoporosis, breast cancer and cardiovascular disease. In addition, recently published studies prompted patients, clinicians and payers to re-examine the risks and benefits of a well-accepted therapy to treat postmenopausal symptoms. The objective of this paper is to provide a framework for assessing the economic impact of disorders affecting postmenopausal women, with a particular focus on osteoporosis, breast cancer and cardiovascular disease. This framework considers the prevalence of these conditions, the profiles of women suffering from each of them and prevailing patterns of treatment for these disorders. Taken together, these factors are used to analyse the overall economic impact of postmenopausal disorders and to provide an expert opinion in this context.

Economic burden of osteoporosis, breast cancer, and cardiovascular disease among postmenopausal women in an employed population.

BACKGROUND: Postmenopausal women have a significant risk of developing a number of chronic conditions including osteoporosis (OP), breast cancer (BrCa), and cardiovascular disease (CVD). These diseases can result in significant direct (medical treatment) and indirect (workplace) costs. The objective of this study is to assess these costs among an employed population. METHODS: Deidentified medical and disability claims data from seven large employers (n = 585,441) were analyzed from 1998 through 2000 for female employees, age 50-64 years. Medical claim ICD-9CM codes were used to identify patients treated for: OP (n = 2,314), BrCa (n = 555), and CVD (n = 1,710). Each disease cohort was compared to a random sample of 50- to 64-year-old female employees (n = 7,575). Descriptive and multivariate techniques were used to characterize direct and indirect costs attributable to each condition. RESULTS: Average annual direct costs were higher (p < .001) for female employees treated for OP (6,259 dollars), BrCa (13,925 dollars), or CVD (12,055 dollars) when compared with the random sample (2,951 dollars). In addition, average annual indirect costs associated with OP (4,039 dollars), BrCa (8,236 dollars), and CVD (4,990 dollars) were higher (p < .001) than indirect costs for the random sample (2,292 dollars). Even when controlling for each disease-state cohort's demographics and disease-specific comorbidities, patients treated for OP, BrCa, and CVD continued to have significantly greater direct and indirect costs (p < .001) than the random sample. CONCLUSIONS: Chronic conditions such as OP, BrCa, and CVD, which occur more frequently in women after menopause, impose a significant financial burden. Greater health care utilization and work-loss prevalence among women treated for these conditions contribute to these additional costs.
