Economic evaluation of a tertiary telepsychiatry service to an island.

The island of Jersey is located 160 km south of Britain and 23 km from northwest France. The island has well-established primary and secondary mental health services, but tertiary services have to be purchased from UK mainland service providers. A pilot study of telepsychiatry was conducted, using videoconferencing to access tertiary mental health services from the UK. During a six-month study period, five patient consultations and six specialist presentations were carried out. The total cost of using videoconferencing to deliver tertiary mental health services not ordinarily available in Jersey was 3483.06 pounds. The costs of using the traditional model instead would have been 12,975.00 pounds. The threshold at which videoconferencing became cheaper than travel was between five and six telemedicine episodes per year; the actual workload during the pilot study was 22 episodes per year. The study suggests that telemedicine is cost-effective for providing tertiary mental health services not ordinarily available in Jersey.
