[A study on the LIS and HIS integration].

The development of hospital business demands the integration of information systems. After studying the relative technologies for system connection,system integration and different modes of connecting system, we put forward a protocol to integrate the existing laboratory information system( LIS) and hospital information system(HIS). It introduces the multi-tier distributed technical methods for improving the client/server applications; it ascertains the units and transactions participating in workflow integration by referencing the IHE( Integrating the Healthcare Enterprises) Laboratory Technology Framework; it implements information exchange by Health Level 7(HL7) standards; and it can conserve previous investment and avoid some problems of security, maintenance and realtime process without the risk of massively updating system.
