Dr David Rowell presented a research paper on behalf of Tho Dang titled “An Economic Evaluation of Deep Brain Stimulation for Patients with Tourette’s syndrome: An Initial Exploration” (Dang, T., Rowell, D., Liddle, J., Coyne, T., Silburn, P. & Connelly L.) as a keynote address to the 8th European Neurology Congress and represented the research on the 28th of September to the XXII Congress of the European Society for Stereotactic and Functional Neurosurgery (ESSFN) Madrid, Spain. This research will form a component of Tho’s dissertation.
Tourette’s syndrome (TS) is a neuropsychiatric movement disorder, which is now being treated with deep brain stimulation. No economic evaluation has yet been published. Clinical indices for (i) tic severity (Yale Global Tic Severity Score) and (ii) depression (Hamilton Depression rating Scale) were collected from 17 Australian TS patients pre and post DBS, 2008 to 2012 (Sachdev et al (2014). These clinical data were converted to quality adjusted life years (QALY) using standardised coefficients derived from 200 German outpatients (Müller-Vahl et al 2010). Australian costs for DBS were source and reported in US$. DBS was estimated to improve mean health utilities from 0.45 to 0.78. The ICER was estimated to be approximately $25,000. Preliminary analysis indicates that treating severe TS with DBS is cost effective.
