Public title Clinical effectiveness and cost of repetitive transcranial magnetic stimulation versus electroconvulsive therapy in severe depression: a multi-centre randomised controlled trial and economic analysis
Scientific title Investigating if repetitive transcranial magnetic stimulation (rTMS) was as effective as electroconvulsive therapy (ECT) in treating major depressive episodes and performing a cost-effectiveness analysis.
Acronym N/A
Serial number at source HTA 98/11/04
Study hypothesis 1. To carry out a multi-centre Randomised Controlled Trial (RCT), with 6 months follow-up, of repetitive Transcranial Magnetic Stimulation (rTMS) versus Electroconvulsive Therapy (ECT) in patients with severe depression. Ninety patients will be entered into each arm of the trial, sufficient to obtain a 95% confidence interval to demonstrate equivalence or a subtle difference between rTMS and ECT. The objectives are:
1.1. To determine if rTMS is as effective as ECT
1.2. To determine if rTMS is associated with fewer side effects than ECT
1.3. To identify patient characteristics indicative of a beneficial response to rTMS
1.4. To ascertain patient preference for rTMS or ECT

2. To carry out a cost-effectiveness analysis of the use of rTMS versus ECT. The objectives are:
2.1. To calculate the short and longer term costs of treatment with both rTMS and ECT
2.2. To establish if there are any economic, as well as therapeutic, advantages in the use of rTMS compared to ECT in both the immediate and long term

Please note that, as of 16 January 2008, the start and end date of this trial have been updated from 1 May 2001 and 30 April 2004 to 1 August 2001 and 30 April 2005, respectively.
