Cost‐minimization analysis in the Indian subcontinent for treating Guillain Barre Syndrome patients with therapeutic plasma exchange as compared to intravenous immunoglobulin

摘要

Abstract Background Therapeutic Plasma Exchange (TPE) and Intravenous Immunoglobulin both are first‐line treatments for Guillain Barre Syndrome; however, there is a significant difference in cost. We undertook this study to assess the cost minimization for treating Guillain Barre Syndrome patients. Methods A prospective randomized controlled trial was undertaken, in which 40 Guillain Barre Syndrome (GBS) patients with a GBS disability score of grade four and five were enrolled. A societal perspective was adopted for the analysis and assessment of both the health system cost and out‐of‐pocket expenditures. Cost‐minimization analysis was undertaken as both the treatments were equally effective at the end of 12?weeks. Results No statistically significant differences were observed in the GBS Disability scores during overall treatment course in both treatment groups. The Out‐of‐pocket cost for the immunoglobulin (IVIG) group was INR 219?247 (4298 USD) and for the TPE group was INR 104?070 (2040.5 USD). Overall INR 86?685 ($1700), that is, 53% higher cost was observed in IVIG group without any concomitant health outcome benefit. Conclusion In comparison with IVIG, TPE appears to be the better option for treatment of GBS in cost‐constraint countries like ours to provide an economic treatment option to most average people.
