Economic burden of amyotrophic lateral sclerosis: A Canadian study of out-of-pocket expenses

Abstract

This study quantifies the 'out-of-pocket' expenses incurred by individuals with amyotrophic lateral sclerosis (ALS) and their families, explores cost-driving factors and describes the current state of financial support in a Canadian cohort. We performed structured cost-of-illness interviews with 50 consecutive ALS patients and family members detailing disease-specific factors, direct and indirect costs. Direct costs were divided into 'out-of-pocket' and 'government/non-profit organization (NPO) supported'. Results showed that the average annual direct cost per patient was $32,337, of which $19,574 (61%) was paid for out-of-pocket. The most significant direct cost was disease-related home renovations, which garnered minimal government or NPO support. The costs of mobility aids, medical expenses, and private personal support workers were also substantial. Higher out-of-pocket costs were associated with an ALS Functional Rating Scale gross motor subscore of ≤ 6 (p = 0.03), limb-predominant symptoms (p = 0.04) and > 4 h/week of personal support care (p = 0.005). Annual indirect costs (lost wages) for patients with ALS and family members providing care were $56,821. In conclusion, this study quantified the substantial personal economic impact of ALS as measured by non-reimbursed, out-of-pocket expenses. Mobilization of additional resources for ALS patients and families is required to soften the economic burden of this disabling disease.
