INTEROPERABILITY The ability of diverse systems to work together. Syntactic: the capability of communicating and exchanging data via a specified data format and communication protocol. Semantic: the ability to interpret the information exchanged meaningfully and accurately with an unambiguous, shared meaning To integrate Application/system will communicate within a dedicated IT infrastructure How to send messages? : using HL7 standard How to send data?: data embedded in a structured electronic documents (HL7) How another system/application understand the data? : metadata and content must be standardise i.e. ICD 10 for diagnosis, Snomed CT for Clinical Terminology, LOINC for Lab and document identification, Malaysia Drug Code (MDC) for medication 4

HEALTH INFORMATICS STANDARDS HL7/CDA identifies which fields are variables and values, and determines the sequence of variables MyHDD/DDSA determines the properties of each variable and values related to it e.g. naming convention, data type, field size Variable Value Nama No. ID Jantina Umur Diagnosis Nor 1234 Wanita 30 CA Breast Ah Moi 3456 Female 31 Kanser Payudara Devi 5678 Perempuan 32 Carcinoma Mammae 248152002 254837009 SNOMED-CT/LOINC uniforms the C50.9 meaning of terminologies entered into ICD classifies the uniformed each field. In this example, jantina and meaning for analysis. In this diagnosis example, ICD10 which is WHO s diagnosis classification standard. 8
Malaysian Health Data Dictionary
Overview Health Information Management in Malaysia is evolving from a basic statistical reporting system through papers and collecting aggregated data to an ICT enabled Health Information Management System and collecting granular data. In order to ensure integration and interoperability between the sources providing health and health related information a systematic approach is necessary for adoption and development of health informatics standards in the country Malaysian Health Data Dictionary is a step towards standardization of health and health and health related information to ensure data quality and integrity and to enhance interoperability
Objectives of Malaysian Health Data Dictionary Make available a Malaysian Health Data Dictionary for the use by individuals and organisations involved in the generation, capture, storage and use of health and health related information esp vendors & developers Consensus among clinician provide semantic understanding of data elements uses in health care industry Conform to nationally agreed protocols and standards i.e. demographic data elements from *Public Sector Data Dictionary by MAMPU Be consistent with international standards wherever possible * Data Dictionary Sektor Awam by Malaysian Administrative Modernisation and Management Planning Unit
Strategy used in the development of MyHDD Identification of stakeholders LHR / EMR components Discipline Process of building of MyHDD Data Dictionary Workshops to develop data elements Consensus driven methodology Review current guidelines and standards in use Endorsement by experts and authorized committees Adoption and application of standards by all healthcare stakeholders including industry partners
