Intervention costs
Training was delivered by trial staff and an allocated cost was estimated which included time for face-to-face delivery and travel to individual care homes. As training would not be expected to be delivered off site in normal working practice the cost of training facilities was not included. The sunk costs for development of the Handbook and DVD were not included. Care home staff time for training and time to deliver the intervention were costed using staff roles reported for delivery of TTNS/sham intervention. Sources which were used to estimate total cost per participant are given in Table
