Abstract
Major depression is one of the most diagnosed mental illnesses in Canada. Generally, people are treated successfully with antidepressants or psychotherapy, but some people do not respond to these treatments (called treatment-resistant depression [TRD]).
Objective
This health technology assessment evaluates the effectiveness, safety, and cost-effectiveness of repetitive transcranial magnetic stimulation (rTMS) for people with treatment-resistant depression (TRD). It also evaluates the budget impact of publicly funding rTMS and the experiences, preferences, and values of people with TRD.
Background
Major depression (also known as clinical depression, major depressive disorder, or unipolar depression) is a serious public health issue resulting in personal, societal, and economic burdens.
Clinical Evidence
Question 1: What are the effectiveness and safety of repetitive transcranial magnetic stimulation (rTMS) compared with sham rTMS for the treatment of adults with treatment-resistant depression (TRD)?
Economic Evidence
What is the cost-effectiveness of repetitive transcranial magnetic stimulation (rTMS) compared with pharmacotherapy and with electroconvulsive therapy (ECT) in adults with treatment-resistant depression (TRD)?
Primary Economic Evaluation
We identified three published Canadian economic evaluations that partially addressed our research questions. 13, 143, 150 However, each of these studies had limitations.
Budget Impact Analysis
What is the potential 5-year budget impact for Ontario's Ministry of Health of publicly funding repetitive transcranial magnetic stimulation (rTMS; high-frequency rTMS, and intermittent theta burst stimulation [iTBS]) in adults with treatment-resistant depression (TRD)?
