Revision as of 23:38, 4 September 2011

The DIOGENE hospital information system has been expanded with a centralized and integrated patient clinical database recording structured patient data. The objective is to provide a standardized framework for the building of future clinical databases and for the integration of existing heterogeneous ones. The combined 'across time view' and 'across departments view' generated from the integrated clinical data will enable an evolutionary view of the patient state, both across time and across medical specialties.

History

Diogene was developed in the 1970's (1) by Professeur Jean-Raoul Scherrer, MD at the University Hospital in Geneva, Switzerland (2). The need for this hospital information system arose as medical expenses had to be directly compared to the quality of healthcare provided (6).

The system had both a centralized patient database, and centralized group of operators who train and support users. The centralized patient database included mechanisms for data protection and recovery of a transaction-oriented system. It also included a separate network of remote printers that provided service throughout the entire institution; and a three-component structure that enhanced communication between administrative and medical applications (1). It retained its architectural unity until Diogene 2 was launched.

In 1993, Unimage, a radiology information system was created and implemented at the Cantonal University Hospital of Geneva as a part of the migration towards the Diogene 2 hospital information system. It was designed to fit the needs of the radiology department, and to operate in different services, (i.e. diagnostic radiology, nuclear medicine and therapy radiology) offering a simple two-way data communication with the PACS world; created for a distributed environment, as well as a graphical (X/Motif) user interface (4).

In June 1995, the need for modification and extension over the years led to the creation of a full-scale distributed/open hospital information system “Diogene 2” (5). "Diogene 2" integrated technology by incorporating knowledge bases such as Medline; providing relevant information for helping the physician to make adequate decision on medico-economical issues to understand resources consumption (6).

In 1999, an effort was made to integrate the many clinical databases that have developed over the years in different hospital departments with "Diogene 2". The challenge was in the different systems developed by different teams with different references and vocabulary (8). Therefore, a newly developed clinical vocabulary was created based on the international ICD classification which facilitated the communication and exchange of data (7).

Doclin is a clinical information system that is integrated with DIOGENE. DOCLIN was created for the communication and the exchange of data between different medical departments at the University of Geneva that had independently created and operated databases. The 4-year project began in 1997. (7)

The purpose of the 4-year project was to expand DIOGENE with clinical data and medical protocals to form the DIOGENE HIS. The new HIS was an open network of information systems managing many types of data. The data types included admission and discharge data, laboratory data, coding and patient medical records. (11)

Diogene now supports many applications including lab, radiology, and pharmacy (2). It went from centralized to an open distributed architecture; therefore, reaching other public hospitals and general practitioners in Geneva.
