Research And Practice Of Hospital Information Systems And Hl7 Applications

It has been a trend of hospital development to constructthe Digital Hospital with the improvement of medical qualityand promotion of service level demanded by the patient, with the increases on the medical equipments, especially thepopularization of the computer and network technology, and application of various kinds of information systems in the hospital.First, in the papers the historic background forconstruction of the Digital Hospital was reviewed. The necessity and importance for DH construction was describedcomparing with the difference between abroad and home indeveloping DH. The constants and the whole framework of DH was also presented here with in the view of paper's author and the five levels of constructions in the DH informationsystems were enumerated in the depth, especially therelevant standards of the medical information that was used in the field of DH within home and abroad, were also pointed out.Secondly, the thinking for construction of DH in our country was presented based on the experience of DH construction in both home and abroad. It has been discussed the content of DH's framework, standand flow of medical operation and standardization of medical information.Thirdly, we gave the ways to solve the problem of data exchange in DH is technology ofHL7.We used much content to discuss how to convert and transmit the standard data by HL7 in the papers. We developed an HL7 gateway for the hospital of SDUTCM.The gateway is used to connect two different medical information systems, a Hospital Information System(HIS) and a Laboratory Information System(LIS), via message exchanging.Much necessary information, data and some key technique for DH construction have been offered. We have done best to try and explore somewhat for promoting DH construction in the hospital of our country.
