ObjectiveTo assess the cost-effectiveness of drotrecogin alfa (activated) therapy, which was recently shown to reduce mortality in severe sepsis. DesignEstimates of effectiveness and resource use were based on data collected prospectively as part of a multicenter international trial. Estimates of hospital costs were based on a subset of the patients treated in the United States (33% of all enrolled patients). Lifetime projections were modeled from published sources and tested in sensitivity analyses. Analyses were conducted from the United States societal perspective, limited to healthcare costs, and using a 3% annual discount rate. SettingA total of 164 medical institutions in 11 countries. PatientsAdults ≥18 yrs of age with severe sepsis. InterventionsEligible patients were randomly assigned to receive a 96-hr intravenous infusion of drotrecogin alfa (acti-vated) at 24 &mgr;g/kg/hr (n = 850) or placebo (n = 840). Measurements and Main ResultsBase Case: incremental short-term (days 1–28) healthcare costs per day-28 survivor; Panel on Cost-Effectiveness in Health and Medicine Reference Case: incremental lifetime healthcare costs per quality-adjusted life-year. Over the first 28 days (short-term Base Case), drotrecogin alfa (activated) increased the costs of care by

27,400 per quality-adjusted life-year when limited to patients with an Acute Physiology and Chronic Health Evaluation II score ≥25 and was cost-ineffective when limited to patients with a score <25. ConclusionsDrotrecogin alfa has a cost-effectiveness profile similar to that of many well-accepted healthcare strategies and below commonly quoted thresholds.

BACKGROUND The Medicare Part D coverage gap has been associated with lower adherence and drug utilization and higher discontinuation. Because osteoporosis has a relatively high prevalence among Medicare-eligible postmenopausal women, we examined changes in utilization of osteoporosis medications during this coverage gap. OBJECTIVES The purpose of this study was to investigate changes in out-of-pocket (OOP) drug costs and utilization associated with the Medicare Part D coverage gap among postmenopausal beneficiaries with osteoporosis. METHODS This retrospective analysis of 2007 pharmacy claims focuses on postmenopausal female Medicare beneficiaries enrolled in full-, partial-, or no-gap exposure standard or Medicare Advantage prescription drug plans (PDPs), retiree drug subsidy (RDS) plans, or the low-income subsidy program. We compared beneficiaries with osteoporosis who were taking teriparatide (Eli Lilly and Company, Indianapolis, Indiana) (n = 5657) with matched samples of beneficiaries who were taking nonteriparatide osteoporosis medications (NTO; n = 16,971) or who had other chronic conditions (OCC; n = 16,971). We measured average monthly prescription drug fills and OOP costs, medication discontinuation, and skipping. RESULTS More than half the sample reached the coverage gap; OOP costs then rose for teriparatide users enrolled in partial- or full-gap exposure plans (increase of 121% and 186%;
