Some successes and limitations with telehealth in Canada.

Canada has taken important steps towards establishing telehealth within its health-care system. However, in many areas telehealth in Canada has yet to progress beyond the stage of testing feasibility. A recent survey of eight Canadian telehealth programmes that are using videoconferencing indicated that there is little evidence of either clinical or economic benefits compared with conventional care. There are examples of sustainable, routine telehealth services in Canada. However, overall, the number of patients seen by telehealth is still very small in comparison with the number of face-to-face visits. 'People-related' factors seem dominant in determining the degree of success of telehealth applications.
