|Effects of Prescription Drug Insurance on Hospitalization and Mortality: Evidence from Medicare Part D|
with , : w19948
We examine whether obtaining prescription drug insurance through the Medicare Part D program affected hospital admissions, expenditures associated with those admissions, and mortality. We use a large, geographically diverse sample of Medicare beneficiaries and exploit the natural experiment of Medicare Part D to obtain estimates of the effect of prescription drug insurance on hospitalizations and mortality. Results indicate that obtaining prescription drug insurance through Medicare Part D was associated with an 8% decrease in the number of hospital admissions, a 7% decrease in Medicare expenditures, and a 12% decrease in total resource use. Gaining prescription drug insurance through Medicare Part D was not significantly associated with mortality.

|The impact of Medicare Part D on Medicare-Medicaid Dual-eligible Beneficiaries' Prescription Utilization and Expenditures|
with , : w14413
Features of Part D gave rise to broad concern that the drug benefit would negatively impact prescription utilization among the six million dual eligible beneficiaries, either during the transition from state Medicaid to Part D coverage, or in the long-run. At the same time, Part D contained other features, such as its auto-enrollment and premium subsidization policies, which were designed to safeguard utilization for this vulnerable group. Using national retail pharmacy claims, we examine the experience of dual eligibles during the first 18 months of Part D. We find no evidence that Part D adversely affected pharmaceutical utilization or out-of-pocket expenditures in the transition period, or in the 18 months subsequent to Part D implementation.
