How Much Does Medication Nonadherence Cost the Medicare Fee-for-Service Program
BACKGROUND: Medication adherence is associated with lower health care utilization and savings in specific patient populations; however, few empirical estimates exist at the population level. OBJECTIVE: The main objective of this study was to apply a data-driven approach to obtain population-level estimates of the impact of medication nonadherence among Medicare beneficiaries with chronic conditions. RESEARCH DESIGN: Medicare fee-for-service (FFS)…
Evaluating the Effects of Pioneer Accountable Care Organizations on Medicare Part D Drug Spending and Utilization
BACKGROUND: The improvement of medication use is a critical mechanism that accountable care organization (ACO) could use to save overall costs. Currently pharmaceutical spending is not part of the calculation for ACO-shared savings and risks. Thus, ACO providers may have strong incentives to prescribe more medications hoping to avoid expensive downstream medical costs. METHODS: We designed a quasinatural experiment study to evaluate the effects o…
E-Prescribing and Adverse Drug Events
BACKGROUND: Although the adoption of e-prescriptions among physicians has increased substantially under the Medicare Improvements for Patients and Providers Act and Meaningful Use programs, little is known of its impact on patient outcomes. OBJECTIVE: To examine the impact of e-prescribing on emergency visits or hospitalizations for diabetes-related adverse drug events (ADEs) including hypoglycemia. DESIGN: This is a prospective, observational co…
Eligibility and Take-up of the Medicare Part D Low-Income Subsidy
There is concern about poor take-up of the Medicare Part D Low-Income Subsidy (LIS), but uncertainty in published estimates. The Medicare Current Beneficiary Survey (MCBS), which contains Medicare LIS enrollment records and extensive survey data on individual beneficiary characteristics, would appear an ideal resource for evaluating LIS take-up. However, use of the MCBS to identify eligible beneficiaries is limited due to underreporting of income…
Predictive Modeling of Total Healthcare Costs Using Pharmacy Claims Data
OBJECTIVE: We sought to evaluate several statistical modeling approaches in predicting prospective total annual health costs (medical plus pharmacy) of health plan participants using Pharmacy Health Dimensions (PHD), a pharmacy claims-based risk index. METHODS: We undertook a 2-year (baseline year/follow-up year) longitudinal analysis of integrated medical and pharmacy claims. Included were plan participants younger than 65 years of age with cont…
