Abstract:
Electronic Health Record (EHR) refers to the complete set of information that resides in electronic form and is related to the past, present and future health status. Health Level Seven (HL7) and Digital Imaging and Communications in Medicine (DICOM) are intensively influencing EHRs standardization. This article describes the development, experience and evaluation of a web-based application, TeleOftalWeb 3.2, to store and exchange EHRs in ophthalmology. We apply HL7 Clinical Document Architecture (CDA) and DICOM standards. EHRs and fundus photographs are stored in a database Oracle 10g. The application has been built on Java Servlet and Java Server Pages (JSP) technologies. For security, all data transmissions were carried over encrypted Internet connections such as Secure Sockets Layer (SSL) and HyperText Transfer Protocol over SSL (HTTPS). The application verifies the standards related to privacy and confidentiality. TeleOftalWeb 3.2 has been tested by ophthalmologists from the Uni
versity Institute of Applied Ophthalmobiology (IOBA), Spain. Nowadays, more than one thousand health records have been included to verify the web application usability.
