In their submission to NICE the manufacturer of BTSteps submitted an economic analysis in which they assumed the programme would cost £200 per person (the price charged by the manufacturer for a minimum of 30 users) and that ten hours of therapist time would be provided to the TCBT group at £69 per hour.
As an outcome measure the model used incremental changes in scores on the Y-BOCS from baseline. Cost effectiveness was presented as cost per unit improvement on the Y-BOCS. A ‘net-benefit’ approach was used to present cost-effectiveness acceptability curves based on a range of hypothetical values that society would place on a unit improvement on the Y-BOCS. Valuing a one-unit improvement in the Y-BOCS score at £50 was associated with a 50% chance of BTSteps being cost effective over relaxation. No comprable analysis of TCBT versus CBT was presented-----
