Abstract
The aim of this bachelor thesis is to give an overview of interfacing hospital information
system with the Health Information System. This work is based on actual implementation
done by the author.
The result of this work is a detailed overview of interfacing the Health Information System
and hospital information system LIISA. It describes how documents are generated and
prepared in LIISA and sent to the Health Information System. It also shows how sent
documents are queried and displayed to users.
First part of this bachelor thesis is purely theoretical and gives small overview of the
Health Information System and information system LIISA. It also provides a brief
introduction to object identificators and HL7 standards, which are used for generating
documents as well as sending and receiving data.
Second part is more practical and includes explicit examples from LIISA. It presents an
overview of how documents are generated and forwarded to the Health Information
System as well as how they are queried and displayed to the user. Documents generation
and forwarding process begins by querying data from database followed by data
transformation. After that it is described how adding a digital signature and sending the
document to the Health Information System works in LIISA. Querying and displaying
documents begins by creating a query to receive a list of sent documents. In the end it is
shown how to query a certain document and display it to the user.
Neither development of the Health Information System nor LIISA is finished. Many new
standards are published and changes made to current ones, which makes implementing
them to LIISA a work in progress.
