The so-called ‘Guyana Telemedicine network’ is a concrete operational case which evidences the decisive impact of networking telemedicine issues in those regions where population is sparse, in isolated or uneasy to access areas. The network developed in Guyana shows it possible and beneficial to link through a network in an operational way local ‘health centres and stations’ (CPS in French) operated by paramedical staffs with a regional hospital centre (here the ‘Centre Hospitalier André Rosemond’ – CHAR) – this one being linked to the ‘external world’ In 2008, thanks to the ‘Guyana Telemedicine network, 381 teleconsultation medical records have been processed the ‘telemedicine Guyane network’ in some ten specialities, coming from 16 health centres and stations.
