Project:

Further development of the 3LGM2 and specification of a reference model for the domain layer of the 3LGM2 of a hospital

Project team:

Gudrun Hübner-Bloder, Peter Efferl, Elske Ammenwerth

Time span:

2003 - 2006

Cooperation partner:

Information Technology for Healthcare (ITH), Innsbruck Tyrolean Provincial Hospitals GmbH (TILAK)

Background:

The main enterprise function of a Hospital Information System is to provide an optimum patient care, including the administration and an economic business management of the enterprise. Hospitals are service enterprises which a high heterogeneous enterprise structure. The main function of the strategic management of a hospital is planning, directing and monitoring of the information system. By describing or modelling of the hospital information system (HIS) it is possible to recognise the heterogeneous enterprise structures. To assist the strategic management of a hospital different meta models of information systems are applied. For the static view of hospital information system the UML-based three-level graph- based meta model (3LGM2) has been developed.

Goals:

Goal of this project is to operate and assist to develop the 3LGM2-method and the respective tool to be an useful tool for the strategic management. As a result of the tight cooperation with the university of Leipzig, the Information Technology for Healthcare (ITH) and the Tyrolean Provincial Hospitals (including the University Hospital and another four hospitals) there is the possibility to influence into the development the know-how, the experiences of the different professional groups. We are also working on reference models for the domain layer. So the availability of reference models would provide a high valuable contribution to keep the costs for the creation of models of hospital information systems within bounds as they only need to be adapted to the respective information system. This may further lead to a more unique terminology and description of the elements of HIS models. Another goal of this project is to define quality parameters to assess a HIS. Additional quality parameters directly based on a 3LGM2 description would further improve strategic IT-management.

Methods:

As a result of the tight cooperation with the university of Leipzig, the Information Technology for Healthcare (ITH) and the Tyrolean Provincial Hospitals (including the University Hospital and another four hospitals) there is the possibility to influence into the development the know-how, the experiences of the different professional groups. This reference model may be based on the requirements index for information processing in hospitals and the objectives of the Health Level 7 Reference Model (HL/-RIM) Version 2.02, HISA and German Frame architecture for Telematics in Health Care and will also adjust with other sources.

Results:

Until now two HIS are described, the HIS of the psychiatric hospital of Hall and the department of dentistry and oral surgery of the hospital of Innsbruck. The next application project is planned. A reference model is in preparation, and we also started to define the quality parameters for a HIS.
