RESUMO
Interoperability is needed when the Hospital Information System [HIS] data should be combined and shared with different systems. This study was aimed to determine the semantic and technical interoperability of hospital information systems of Iran's health care centers and propose guidelines to create and develop interoperability of these centers. This descriptive study was conducted on companies, which were qualified to receive performance appraisal certificate of HIS softwares from statistics and information technology office of health ministry. Standard questionnaire and checklist were used to collect information in the first and second steps. List of companies, which provided and produced HIS in Iran, was obtained, and then a self-administered questionnaire was sent for them. Then, a health care center was selected from each company randomly, and its current HIS interoperability was evaluated. Data were analyzed using SPSS 16. Based on the results, all companies were used Microsoft windows and SQL server database in their HIS with consideration to technical interoperability. Also, the most frequent corporate programming language was Visual C Sharp [46.7%] and Visual Basic [40%], respectively. From semantic interoperability aspect, the most frequent terminology systems were ICD-10 [86.7%], ICD-9CM [66.7%], and CPT [66.7%], respectively. For standard messaging, 60%, 46.7% and 33.3% used XML, DICOM, and HL7 in order. Health system interoperability is divided into two semantic and technical parts. At the present, there is not any standard for electronic health record [EHR] to provide full interoperability. HIS templates should be provided in order to make a national standard for EHR. Therefore, it is necessary to have standard template for semantic and technical interoperability in EHR national exchanges
RESUMO
International Classification of Diseases [ICD] is considered as the most successful product among various activities performed by World Health Organization. However, ICD has faced many challenges due to dynamic environment of needs. The main purpose of this study was to identify ICD challenges and structure of ICD 11 life cycle through a review study of the published papers. A review study was adopted as the methodology of this paper. Data were collected by search strategy in the following databases: NLM, SCIENCEDIRECT, WHO, and ICD 11 related sites. The findings showed that ICD was used in many countries some of which found ICD an insufficient tool for the level of details needed for clinical and administrative uses. In addition, little consideration was given to adaptability of codes and mapping between the ICD-9 to ICD-10 codes. Therefore, WHO initiated a new dynamic architechture based on semantic web application and employed a four stage workflow engine for collecting proposals. This architecture has applied a Semantic Wiki as well as a four stage peer review to provide a three layer ontological structure. ICD11is at the experimental stage and it is predicated that it would have a significant role in the interaction and interoperability of different terminologies leading to the development of Electronic Health Records
