title: Use of HL7 to integrate a HIS-subsystem: limits and possibilities.
abstract: Modern computer-based hospital information systems are mostly distributed with several heterogeneous subsystems connected together by specialized communication services. The common standard to integrate subsystems is HL7. By the example of subsystem integration for a pulmonary function test lab, we discuss the possibilities of HL7, the limits we encountered and how we overcame these.
