Cost of treating rheumatoid arthritis in the primary care public health system in Ireland: A time-driven activity-based cost analysis
Abstract
Background: Chronic diseases are at epidemic proportions and continuing to increase in both incidence and prevalence globally. Therefore, there is a growing need to assess and improve on the value currently provided within chronic care pathways. Examining the costs associated with care pathways is a critical part of assessing this value in order to better understand and introduce potential cost-saving interventions. Objectives: Examining one such chronic disease, Rheumatoid Arthritis (RA), this study aimed to assess the cost associated with RA in primary care within the Health Service Executive (HSE) in Ireland. Methods: Following mapping of the care pathway, patient vignettes based on exemplar RA patient types were used to conduct semi-structed interviews with every member (N = 21) of the primary care RA pathway. Time-Driven Activity-Based Costing (TDABC) was then used to calculate the overall cost of each patient (vignette) type. Results: RA is an expensive condition regardless of disease stage. However, newly diagnosed patients as well as those with advanced disease in need of surgical interventions demonstrated the highest costs in terms of primary care personnel use. Additionally, patients prescribed Biological Disease-Modifying Anti-Rheumatic Drugs (bDMARDs) cost significantly more than those on Conventional Synthetic Disease-Modifying Anti-Rheumatic Drugs (csDMARDs) regardless of disease stage or personnel resource use. Conclusion: RA and a subset of RA patients that exert the highest healthcare costs are growing in prevalence. Therefore, this study contributes by assessing the costs associated with RA in HSE primary care that can facilitate better understanding the current value being provided and improve upon the current care pathway to cut future costs.
