“e-SUWAYA” : e-Health Solution for Sri Lankan Government Hospital using Medical Vocabulary Generating Tool

Abstract

Health services are provided to Sri Lankan citizens free of charge. Adoption of new IT technologies in health care sector is not rapidly growth because of the financial barrier. Therefore Sri Lankan government hospitals have more paper based data records and less software solution. It explores the possibilities achievable for the introducing the re-engineering clinical processes of the Sri Lankan government hospitals and how Open Medical Standards is adoptable to the Sri Lankan health care system. There are major 27 re-engineering clinical processes (frequently and non-frequently used) which are categorized into 5 sections. There are Patient Registration & EHR, Investigation Results, Supply Chain Management, Support Service Management and Death Certification. Research on Open Medical Standards like as HL7, DICOMM, ICD 10 and etc… Based on Research, identified HL7 V2/V3 messages which analyze the all above clinical processes and convert into the software solution. HL7 messages have given raw format. It has Message header, Message type, Segments and fields. Message Header has header information. Message type has several segments and segment has several fields which like as SOAP message. The medical generating tool is required to generate these HL7 message into XML format. Hapi Parser is used create HL7 messages which convert Java Language to XML format. Web services use as communication path which are required transfer these message. Mirth Connect Server Administration receives HL7 message in XML format then it convert into the raw message format. It analysis it and create reply message with relevant information. Mirth Connect send reply message to Hapi Parser. Hapi Parser analyzes reply message and sends the data to back end or front end. The “e – SUWAYA” open source solution is proposed for this problem. It is developed using a SOA, leveraging open source and using HL7 open medical standards and Mirth Connect Server Administration.
