3 Brief History of HIS in Korea late 1970s: Account (ex: FACOM M160) 1980s: Ancillary systems (ex: clinical pathology) mid 1990s: The first POE and PACS - win32, C/S late 1990s: PACS expansion in Korea 1999: Oct. 15th- POE in SNUH EMR in Korea-outpatient 2001: 2003: PACS in SNUH Digital Hospital in SNUBH with EMR, PACS, POE, etc.

4 Present status of HIS in Korea General Hospitals with over 100 inpatient-beds System Implementation POE PACS EMR 72.6% (149 / 205 hospitals) 38.7% (77 / 199 hospitals) 2.6% (5 / 190 hospitals)

5 Present status of HIS in Korea 5 Standardization in HIS Transfer format: DICOM, HL7 Disease code SNOMED CT ICD-10 Modification of ICD-10 EDI code Procedure code SNOMED CT Modified ICD-9-CM EDI code local code Symptom code SNOMED CT UMLS Modification of ICD-10

6 Present status of HIS in Korea 6 National wide electronic data interoperability No Standard in data content No Standard in data format No Standard in medical terminology except ICD-10 and EDI code Try to adopt international standards in these fields

36 Vision for HIS in Korea Short term vision Long term vision Obstacles to be resolved

37 Short term vision More convenient than paper record Data retrieval in many aspects on point of care Convenient management of medical record form User defined data abstraction Flow sheet User friendly interface 2. Clinical Data Repository Extend standardization to structured medical record User operated data retrieval for research 3. More sophisticated Clinical Decision Support System 4. Computerized Critical Pathway, Guideline, and Protocol 5. Evaluation module for quality assurance

38 Long term vision Shared EHR * Standardization Syntactic standardization Semantic standardization * Networking? ubiquitous healthcare 2. Patient centered EHR

39 Obstacles to be resolved in institutions Leadership 2. Strategic investment : effect vs cost 3. Define and modify business process 4. Integration legacy systems 5. Encourage participation of users in development process 6. Handle the paper medical record 7. Prepare to share medical data

40 Obstacles to be resolved in national base Security, Privacy, Confidentiality 2. Standardization 3. Regulation by law 4. Financial support
