OBJECTIVES: The purpose of this study was to develop clinical decision support systems (CDSS) that are integrated with hospital information systems for the differential diagnosis of idiopathic pulmonary fibrosis (IPF). METHODS: The integrated CDSS were validated and evaluated by physicians. Knowledge modeling for diagnosing IPF was performed by knowledge working groups, composed of radiologists and respiratory specialists. In order to develop the model for CDSS diagnosis, the clinical cases were collected from 290 cases from Seoul National University Hospital and Sevrance Hospital of Yonsei University. For the evaluation of integrated CDSS, interviews were conducted with respiratory specialists and radiologist 2 weeks after applying CDSSs in clinical settings. The CDSS was integrated with the computer vision system (CVS) and diffuse parenchymal lung diseases (DPLD), CDSS developed in our previous project. RESULTS: Eighteen cases diagnosed as IPF were applied to the collection of diagnostic knowledge and the refined knowledge, the former diagnosed 1 case (6%) and the latter diagnosed 14 cases (78%). Therefore, the refined knowledge performed better than collected knowledge. The validation results of integrated CDSSs showed that 81 cases (74.3%) were diagnosed correctly. CONCLUSIONS: There were 109 cases of IPF diagnosed and initiated on treatment. The significance of this study is in developing integrated CDSS with PACS by acquiring and redefining the knowledge needed for IPF diagnosis. In addition, it is significant for the integration of CDSS to verification and clinical evaluation.

The purpose of this study was to develop a database system for visiting nurses working in a community health center. The final goal of the system is for it to be used as a nationwide database-collecting tool over the Internet for community health services. Three unique systems were developed and trialed. The first system focused on the data warehousing technology as a research centered system for a theory based database construction. The second system was a local system, which has already been utilized in a proactive health center, and had the system interface revised according to the newly developed standardized framework of the service. The third system was part of the integrated community health information system, which had the goal of general dissemination. It is clear that these systems reflect the unique characteristics and goals of the test sites, and should be supported for the Systems Life Cycle to survive. The authors plan to move to the next stage of developing an integrated nationwide health information system for community health services.
