a flexible web oriented telehealth platform using a rim-hl7 based model
This article presents a web oriented telehealth platform adapted to the social and economic conditions of a developing country like Colombia. The platform aims to satisfy health care needs integrating modules for telemedicine, where medical processes are modelled following the HL7 Reference Information Model which has allowed easy inclusion of many specialities such as dermatology, radiology, cardiology, pathology and infection diseases, among others. The system implements many security mechanisms such as Digital Signature and Zero Knowledge Proof for authentication. A telecare real-time module measures patient's vital signs such as blood pressure, electrocardiogram, oxygen saturation and sends them over the network to monitor patient's health. After 19 months of service, the system processed 4.751 actual telemedicine cases from 31 remote stations with an average response time of 1, 3 days, showing flexibility, security and scalability.
