Introduction: To estimate the value of interventions in multiple sclerosis (MS) - where lifetime costs and outcomes cannot be observed - outcome data have to be combined with costs. This requires that cost data be regularly updated.
Objectives and methods: This study is part of a cross-sectional retrospective study in 16 countries collecting data on resource consumption and work capacity, health-related quality of life (HRQoL) and prevalent symptoms for patients with MS. Descriptive analyses are presented by level of severity, from the societal perspective, in EUR 2015.
Results: A total of 382 patients (mean age: 54 years) participated in the Netherlands; 81% were below retirement age and of these, 31% were employed. Employment was inversely related to disease severity, and MS affected productivity at work for 82% of patients. Overall, 96% and 73% of patients experienced fatigue and cognitive difficulties, respectively, as a problem. Mean utility and annual costs were 0.744 and €23,100 at Expanded Disability Status Scale (EDSS) 0-3, 0.595 and €32,300 at EDSS 4-6.5, and 0.297 and €50,500 at EDSS 7-9. The mean cost of a relapse was estimated at €3000.
Conclusion: This study provides current data on MS in the Netherlands that are important for the development of health policies and to estimate the value of current and future treatments.
