10 History and Development of Telemedicine in Taiwan

11 Why Telemedicine? Geographic:75% mountainous area, several groups of isolated islets Poor medical resources in rural area Physicians are reluctant to practice in rural area Afraid of being isolated Lacking opportunities for CME Specific needs: Handicapped and Elderly Home care(palliative medicine)

12 History of Telemedicine 1990 TANet (Taiwan Academic Network) 1994 NII (National Information Infrastructure) Planning 1995 NII Kickoff (National Health Insurance started) 1996 NII Pilot Telemedicine projects: Medical Distance Education Teleconsultation 2000 HIN 2.0 (National Health Information Network version 2) EMR
