IHE published a series of technical frameworks to provide solutions to integrating healthcare information systems,and tests vendors’ systems at carefully planned and supervised events called Connectathons.The testing event in China substantiated that the interoperability problems in IHE still existed when using Chinese characters.Through analyzing Chinese character sets adopted in DICOM and HL7 standard,which were adopted in IHE Chinese character set,we found the inconsistency between two standards,and no guidance existing in IHE technical framework.By contrasting the stipulations of DICOM and the HL7 Chinese character codings,we commanded GB 18030—2000 and ISO-IR-192 as the IHE Chinese character set in order to solve the interoperability problem.
