Profile of medical care costs in patients with amyotrophic lateral sclerosis in the Medicare programme and under commercial insurance

摘要

Objective: To determine amyotrophic lateral sclerosis (ALS)-associated costs incurred by patients covered by Medicare and/or commercial insurance before, during and after diagnosis and provide cost details. Methods: Costs were calculated from the Medicare Standard Analytical File 5% sample claims data from Parts A and B from 2009, 2010 and 2011 for ALS Medicare patients aged 70 years (monthly costs) and similar to 65 years (costs associated with disability milestones). Commercial insurance patients aged 18-63 years were selected based on the data provided in the Coordination of Benefits field from Truven MarketScan (R) in 2008-2010. Results: Monthly costs increased nine months before diagnosis, peaked during the index month (Medicare: $10,398; commercial: $9354) and decreased but remained high post-index. Costs generally shifted from outpatient to inpatient and private nursing after diagnosis; prescriptions and durable medical equipment costs were much higher for commercial patients post-diagnosis. Patients appeared to progress to disability milestones more rapidly as their disease progressed in severity (14.4 months to non-invasive ventilation [NIV] vs. 16.6 months to hospice), and their costs increased accordingly (NIV: $58,973 vs. hospice: $76,179). Conclusions: For newly diagnosed ALS patients in the U.S., medical costs are substantial and increase rapidly and substantially with each disability milestone.
