Objective

Background BACKGROUND: The Affordable Care Act provided for a 50% reduction in patient burden for Medicare Part D coverage gap (CG) beginning in 2011.

Design/Methods DESIGN/METHODS: This retrospective study uses the IMS Longitudinal prescription database, LRx and Plantrak managed care data. Patients, stratified by payer type, were evaluated on medication usage and spending patterns before, during and after the CG. The percentages of patients reaching the CG and catastrophic coverage (CC) and time to each spending threshold were determined. A control group of PD patients > 65 years old enrolled in commercial plans, stratified by spending thresholds relative to the CG and CC levels was used.

Results RESULTS: In 2010, 40.9% of Part D standard benefit patients reached CG and 27.3% of these reached CC, while in 2011, 38.8% of Part D standard patients reached the CG and 29.2% of these patients went on to reach catastrophic coverage. The average time in the CG was 4.85 months in 2010 and 4.83 months in 2011. The percentage of patients who remained on therapy increased marginally from 80 to 81% between 2010 and 2011. The percentage of patients who stopped or reduced therapy remained the same at 10% and 1% respectively. For patients that reached the coverage gap, their average pharmaceutical spending was less when compared with their commercial controls in both years, and this spending was primarily driven by non-PD medications.

Conclusions CONCLUSIONS: The percentage of patients reaching the coverage gap level of spending were similar between the Medicare Part D and commercial control groups in both years, however the Part D benefit patients spent less than the commercial control group while in the CG and CC.
