Integrating a Computerized Clinical Laboratory Information System into a Global Hospital Information System

摘要

We have developed Laboratory (LIS) and Hospital (HIS) Information Systems in a distributed, shared satellite-host configuration. The LIS processes data on-line from 25 electronic analytical instruments from two geographically separated hospital units connected on-line to a laboratory computer (LDM). Manual test results are entered by CRTs or punch cards. Free Text is entered by CRT or CMC/ST. Machine readable specimen identification is accomplished by OCR or mini-punch card readers attached to the test instruments. The LDM transmits all test data to the HIS for storage in patients' files.The HIS is an IBM 4341 and serves both hospital units through 8100's. It performs all administrative tasks. The LIS is the Technicon 7000R system.A communication system, DIVOTS (Data Voice Output Telephone System) is based on an IBM S/7 processor coupled to the 4341 and uses Touch-Tone, Audio-Response technology. It provides test order entry and result inquiry functions between nursing stations, clinics and physicians' offices to and from the laboratory and other departments. HIS prints all interim and daily updated, reformatted, cumulative patient summary reports which are sent to the wards.
