Intranet Meets Hospital Information Systems: The Solution to the Integration Problem?

Analysing the Scientific Publications of Peter Reichertz: Reflections from the Perspective of Medical Informatics Knowledge Today

Professor Peter L. Reichertz is one of the most significant pioneers in the field of medical informatics worldwide. In 1969, 50 years ago, he became Professor at the Hannover Medical School. On the occasion of this anniversary an attempt was made to report on the scientific work of Peter Reichertz and to reflect on this work in the light of medical informatics knowledge today. The aim of this study was to search publications listings in the Peter L. Reichertz Archive, in Pubmed/Medline, and in the Web of Science. As well as to analyse contents and communication approaches to help in classifying Peter Reichertz's scientific publications. Three comprehensive publication lists were identified: the Print Bibliography (384 publications), the Disc Bibliography (285 publications) and the Selected Publications Bibliography (111 publications). Based on the last bibliography, a classification was built along the semantic dimensions of (1) major topics, (2) fields of publication, and (3) publication languages. Major contents of Peter Reichertz's research in informatics were medical informatics as a field (including education), informatics applications in medicine and health care, and health information systems. Clear shifts over time were observed. To his research on informatics applications, in the 1970s health information systems was added as topic, which then became a major part of his research. While in the 1960s and earlier German was a major publication language, from the 1970s onwards this shifted to English as the major language. Peter Reichertz very early identified the potential of computers in medicine and health care. He did not just use information and communication technology and information processing methodology as if they were other technology, such as microscopes or ultrasonic devices, for improving diagnosis and therapy. He was visionary enough to very early see the revolutionary potential of informatics for biomedicine and health care, with consequential impact on research and education.

On Teaching International Courses on Health Information Systems. Lessons Learned during 16 Years of Frank - van Swieten Lectures on Strategic Information Management in Health Information Systems

Background

Health information systems (HIS) are one of the most important areas for biomedical and health informatics. In order to professionally deal with HIS well-educated informaticians are needed. Because of these reasons, in 2001 an international course has been established: The Frank – van Swieten Lectures on Strategic Information Management of Health Information Systems.

Objectives

Reporting about the Frank – van Swieten Lectures and about our students‘ feedback on this course during the last 16 years. Summarizing our lessons learned and making recommendations for such international courses on HIS.

Methods

The basic concept of the Frank – van Swieten lectures is to teach the theoretical background in local lectures, to organize practical exercises on modelling sub-information systems of the respective local HIS and finally to conduct Joint Three Days as an international meeting were the resulting models are introduced and compared.

Results

During the last 16 years, the Universities of Amsterdam, Braunschweig, Heidelberg/Heilbronn, Leipzig as well as UMIT were involved in running this course. Overall, 517 students from these universities participated. Our students‘ feedback was clearly positive. The Joint Three Days of the Frank – van Swieten Lectures, where at the end of the course all students can meet, turned out to be an important component of this course. Based on the last 16 years, we recommend common teaching materials, agreement on equivalent clinical areas for the exercises, support of group building of international student groups, motivation of using a collaboration platform, ensuring quality management of the course, addressing different levels of knowledge of the students, and ensuring sufficient funding for joint activities.

Conclusions

Although associated with considerable additional efforts, we can clearly recommend establishing such international courses on HIS, such as the Frank – van Swieten Lectures.

Semantic integration in healthcare networks

A seamless support of information flow for increasingly distributed healthcare processes requires to integrate heterogeneous IT systems into a comprehensive distributed information system. Different standards contribute to ease this integration. In a research project focussing on the development of a reference architecture for inter-institutional health information systems, we identified concurring standards currently in use. We therefore categorized these integration standards by distinguishing between technical and semantic integration on the one hand, and data and functional integration on the other hand. In addition, standards for semantic integration are roughly categorized according to their scope. By placing standards into a corresponding matrix a "semantic gap" is revealed, which cannot be covered by standards as it contains volatile medical concepts. As a conclusion, it is recommended to conceptually consider the necessity of system evolution in system architectures and also in future integration standards.

[KIS-RIS-PACS integration: the Marburg approach]

When describing the development of data processing at the Department of Radiology at the Philipps University of Marburg, three phases can be identified covering the areas of patient care, education, and research as well as administrative and organizational aspects. The first phase (1987-1995) was centered on radiology and characterized by the early implementation of the radiology information system (RIS) and installation of a picture archiving and communication system (PACS). The experiences gained during this phase led to intensive discussion on application-oriented information processing. The second phase (1996-2000) describes the changes in the general framework brought by Internet technology and international standards. The course was set for the future of data processing in the hospital setting. The phase ended with implementation of a clinical workplace system (KAS) as the basis for a comprehensive electronic patient record and the switch in radiology to an integrated RIS solution. The third phase (2001-2006) addressed further implementation and development of clinical data management in which both regular documentation of patient data and information processing not related to patients are optimized by making use of Intranet/Internet technology. It includes the hospital wide implementation of PACS and the forthcoming phase of information processing increasingly shaped by workflow and decision support.

Technology-enabled knowledge translation: frameworks to promote research and practice

Knowledge translation articulates how new scientific insights can be implemented efficiently into clinical practice to reap maximal health benefits. Modern information and communication technologies can be effective tools to help in the collection, processing, and targeted distribution of information from which clinicians, researchers, administrators, policy makers in health, and the public can benefit. Effective implementation of knowledge translation through the use of information and communication technologies, or technology-enabled knowledge translation (TEKT), would benefit both the individual health professional and the health system. Successful TEKT in health requires cultivation and acceptance in the following key domains: Perceiving types of knowledge and ways in which clinicians acquire and apply knowledge in practice. Understanding the conceptual and contextual frameworks of information and communication technologies applied to health systems, particularly the push, pull, and exchange communication models. Comprehending essential issues in implementation of information and communication technologies and strategies to take advantage of emerging opportunities and overcome existing barriers. Establishing a common and widely acceptable evaluation framework in order that researchers can compare various methodologies in their rightful contexts in TEKT research and adoption. Achieving harmony and common understanding in these areas will go a long way in fostering a fertile and innovative environment to encourage research and advance understanding in this exciting domain of TEKT.
