Section 2: Patient Records: The Computerized Patient Record: Where Do We Stand?

To provide an overview of trends in research, developments and implementations of the computerized patient record (CPR) of the last two years.

We surveyed the medical informatics literature, spanning the years 2004-2005, focusing on publications on CPRs.

The main trends revealed were: 1) the development of technologies to realize privacy and security goals or remote data entry and access to CPRs; 2) investigations into how to enhance the quality and reuse of CPR data; 3) the development and evaluation of decision support functions to be integrated with CPRs; 4) evaluations of the impact of CPRs on clinicians, patients, clinical work settings and patient outcomes; and 5) the further development and use of standards to move towards shared electronic health records (EHRs).

The CPR is playing a growing part in medical informatics research and evaluation studies, but the goal of establishing a comprehensive lifelong EHR is still a long way off. In moving forward to EHRs, convergence of EHR standards seems required to realize true interoperability of health care applications. User acceptance of present-day CPRs (for all categories of users) and compatibility with work patterns has not been achieved yet, and can only be realized by giving these goals high priority. This will require substantial resources for in-depth work flow analysis, development and evaluation of CPRs. Besides this, the implementation of effective CPRs asks for health care organizations that are willing to invest in new developments and to contribute to evaluation studies, to further improve CPRs’ functionalities and enhance their use in practice.

In addition, a mailing list was installed to facilitate communication between all persons interested in HMI education. For subscription a message has to be sent to “listserv@listserv.net”. The body of the message should read “SUBSCRIBE IMIA-WG1”. Messages to the IMIAWG1 list have to be sent to “imia-wg1@urzinfo.urz.uni-heidelberg.de”.

Medical Informatics and the Quality of Health: New Approaches to Support Patient Care

Objectives: The Yearbook of Medical Informatics is published annually by the International Medical Informatics Association (IMIA) and contains a selection of excellent papers on medical informatics research which have been recently published (www.yearbook.uni-hd.de). The 2003 Yearbook of Medical Informatics took as its theme the role of medical informatics for the quality of health care. In this paper, we will discuss challenges for health care, and the lessons learned from editing IMIA Yearbook 2003.

Results and Conclusions: Modern information processing methodology and information and communication technology have strongly influenced our societies and health care. As a consequence of this, medical informatics as a discipline has taken a leading role in the further development of health care. This involves developing information systems that enhance opportunities for global access to health services and medical knowledge. Informatics methodology and technology will facilitate high quality of care in aging societies, and will decrease the possibilities of health care errors. It will also enable the dissemination of the latest medical and health information on the web to consumers and health care providers alike. The selected papers of the IMIA Yearbook 2003 present clear examples and future challenges, and they highlight how various sub-disciplines of medical informatics can contribute to this.

Medical Informatics Specialists: What Are their Job Profiles?

Objectives: Since 1972, the University of Heidelberg and the University of Applied Sciences Heilbronn have jointly been running a medical informatics program. To continuously provide high quality education, the curriculum is regularly evaluated among its graduates. The objectives of this study were to assess the job situation of the graduates and to evaluate the curriculum from their viewpoint.

Method: Anonymous inquiry of all medical informatics graduates, having finished their studies before March 31, 2001 (n = 1024) using a structured questionnaire.

Results: The questionnaire was answered by 446 (compliance: 45.5%) graduates. About one third (146 of 444 valid cases) are working in software/ hardware companies. 179 (43.0% of 416 valid cases) graduates are working within medical informatics, 214 (51.4%) are working outside of medical informatics, but within other informatics. 23 (5.5%) graduates are working neither in medical nor in other informatics. 15 percent of the responding graduates have received a doctor’s degree. Software engineering, database and information systems are regarded as most important parts of the education. The majority of the graduates are satisfied with their education as well as with their personal career.

Conclusions: The variety of jobs, the job profiles, and the high level of our graduates’ satisfaction with their education indicate the relevance of specialized medical informatics programs with a curricular profile like the one in Heidelberg/Heilbronn. Investigations like this can help to adjust the contents of the curriculum to professional needs.

Digital Libraries and Recent Medical Informatics Research

The Yearbook of Medical Informatics is published annually by the International Medical Informatics Association (IMIA) and contains a selection of recent excellent papers on medical informatics research (http://www.med.uni-heidelberg.de/mi/yearbook/index.htm). The special topic of the just published Yearbook 2001 is “Digital Libraries and Medicine”. Digital libraries have changed dramatically and will continue to change the way we work with medical knowledge. The selected papers present recent research and new results on digital libraries. As usual, the Yearbook 2001 also contains a variety of papers on other subjects relevant to medical informatics, such as Electronic Patient Records, Health Information Systems, Health and Clinical Management, Decision Support Systems, Education, as well as Image and Signal Processing. This paper will briefly introduce the contributions covering digital libraries and will show how medical informatics research contributes to this important topic.

An Integrated Approach for a Knowledge-based Clinical Workstation: Architecture and Experience

Today, the demand for medical decision support to improve the quality of patient care and to reduce costs in health services is generally recognized. Nevertheless, decision support is not yet established in daily routine within hospital information systems which often show a heterogeneous architecture but offer possibilities of interoperability. Currently, the integration of decision support functions into clinical workstations is the most promising way. Therefore, we first discuss aspects of integrating decision support into clinical workstations including clinical needs, integration of database and knowledge base, knowledge sharing and reuse and the role of standardized terminology. In addition, we draw up functional requirements to support the physician dealing with patient care, medical research and administrative tasks. As a consequence, we propose a general architecture of an integrated knowledge-based clinical workstation. Based on an example application we discuss our experiences concerning clinical applicability and relevance. We show that, although our approach promotes the integration of decision support into hospital information systems, the success of decision support depends above all on an adequate transformation of clinical needs.

On the Necessity of Systematically Planning Clinical Tumor Documentation

Tumor documentation is an important task for both clinical research and patient care. Documentation systems for these purposes have to be planned systematically and should be goal oriented. We applied the method of a so-called ‘standardized documentation protocol’ for systematically planning two documentation systems in oncology: one for the tumor center Heidelberg/Mannheim and the other for a nationwide project in the field of documentation and therapy planning in pediatric oncology. The method proved to be helpful in both cases even though the resulting documentation protocols are completely different and although they served different objectives. Therefore, the aim of the paper is to motivate and help medical informatics professionals to systematically plan other documentation systems using this method.

Medical Imaging Informatics and Medical Informatics: Opportunities and Constraints

Objectives: The Yearbook of Medical Informatics is published annually by the International Medical Informatics Association (IMIA) and contains a selection of recent excellent papers on medical informatics research (http://www.yearbook.uni-hd.de). The 2002 Yearbook of Medical Informatics took as its theme the topic of Medical Imaging Informatics. In this paper, we will summarize the contributions of medical informatics researchers to the development of medical imaging informatics, discuss challenges and opportunities of imaging informatics, and present the lessons learned from the IMIA Yearbook 2002.

Results and Conclusions: Medical informatics researchers have contributed to the development of medical imaging methods and systems since the inception of this field approximately 40 years ago. The Yearbook presents selected papers and reviews on this important topic.

In addition, as usual, the Yearbook 2002 also contains a variety of papers and reviews on other subjects relevant to medical informatics, such as Bioinformatics, Computer-supported education, Health and clinical management, Health information systems, Knowledge processing and decision support, Patient records, and Signal processing.

Information Processing in Healthcare at the Start of the third Millennium: Potential and Limitations

The 21st century is said to be a century of the information society. We should be aware that continuing progress in information processing methodology (IPM) and information and communication technology (ICT) is changing our societies, including medicine and health care. At the start of the third Millennium we should ask ourselves, what progress can we expect from modern IPM/ICT for healthcare in the coming decade, what concerns does the information society have to face, and what steps have to be taken. These questions were addressed by clinicians, researchers and industrial representatives in a panel discussion at the joint conference ISCB-GMDS-99 of the International Society of Clinical Biostatistics and the German Society for Medical Informatics, Biometry and Epidemiology. Important aspects raised by the panelists and in the subsequent discussion were: (1) the main goal of expanding IPM/ICT should be to further improve quality of care, while maintaining reasonable costs; (2) with the support of modern IPM and ICT the boundaries between inpatient and outpatient care will fade away enabling a more efficient, patient-centered health care; (3) cooperation between health-care professionals will increase; there will be different ways of communication between them and with the patient, including modern ICT and the Internet; (4) society must be concerned with achieving equal opportunities in being informed about and in using new ICT; (5) misuse of data will remain a serious problem and can become an obstacle to progress.

The Challenge of Ubiquitous Computing in Health Care: Technology, Concepts and Solutions

Objectives: To review recent research efforts in the field of ubiquitous computing in health care. To identify current research trends and further challenges for medical informatics.

Methods: Analysis of the contents of the Yearbook on Medical Informatics 2005 of the International Medical Informatics Association (IMIA).

Results: The Yearbook of Medical Informatics 2005 includes 34 original papers selected from 22 peer-reviewed scientific journals related to several distinct research areas: health and clinical management, patient records, health information systems, medical signal processing and biomedical imaging, decision support, knowledge representation and management, education and consumer informatics as well as bioinformatics. A special section on ubiquitous health care systems is devoted to recent developments in the application of ubiquitous computing in health care. Besides additional synoptical reviews of each of the sections the Yearbook includes invited reviews concerning E-Health strategies, primary care informatics and wearable healthcare.

Conclusions: Several publications demonstrate the potential of ubiquitous computing to enhance effectiveness of health services delivery and organization.

But ubiquitous computing is also a societal challenge, caused by the surrounding but unobtrusive character of this technology. Contributions from nearly all of the established sub-disciplines of medical informatics are demanded to turn the visions of this promising new research field into reality.

CSI-ISC

Objectives: The introduction of information system components (ISCs) usually leads to a change in existing processes, e.g. processes of patient care. These processes might become even more complex and variable than before. An early participation of end users and a better understanding of human factors during design and introduction of ISCs are key factors for a successful introduction of ISCs in health care. Nonetheless no specialized methods have been developed until now to systematically support the integration of ISCs in existing processes of patient care while taking into account these requirements. In this paper, therefore, we introduce a procedure model to implement Concepts for Smooth Integration of ISCs (CSI-ISC).

Methods: Established theories from economics and social sciences have been applied in our model, among them the stress-strain-concept, the contrastive task analysis (KABA), and the phase model for the management of information systems.

Results: CSI-ISC is based on the fact that while introducing new information system components, users experience additional workload. One essential aim during the introduction process therefore should be to systematically identify, prioritize and ameliorate workloads that are being imposed on human beings by information technology in health care. To support this, CSI-ISC consists of a static part (workload framework) and a dynamic part (guideline for the introduction of information system components into existing processes of patient care).

Conclusions: The application of CSI-ISC offers the potential to minimize additional workload caused by information system components systematically. CSI-ISC rationalizes decisions and supports the integration of the information system component into existing processes of patient care.

Standardized Documentation of Drug Recommendations in Discharge Letters

Objectives: To analyze the necessity and potential usefulness of a computerized physician order entry (CPOE) system in supporting the writing of pharmacotherapeutic recommendations in discharge letters.

Methods: Systematic analysis of drug recommendations in discharge letters of a hospital providing tertiary care, structured interviews with in-hospital prescribers, and focus groups with general practitioners who admit patients to this hospital.

Results: We analyzed 1800 randomly selected discharge letters, 1205 of which contained pharmaco-therapeutic recommendations. The frequencies, structure, and quality of these recommendations varied considerably between departments. Nearly 16% of the recommendations contained both proprietary (brand) and non-proprietary names (active ingredient). Interviewed clinicians expressed interest in CPOE systems that check for contraindications and interactions between drugs, suggest cheaper products, and automatically insert active ingredients when omitted. The focus group sessions confirmed that the pharmacotherapeutic recommendations in current discharge letters do not effectively support daily clinical practice.

Conclusions: Documenting active ingredients as well as brand names in drug therapy recommendations is currently not part of clinical practice. Computerized decision support can help to optimise the structure and communication of therapeutic information across interfaces and can be a quality factor with considerable influence on process quality, outcome quality, and costs of cooperative patient care.

A Meta-Model of Chemotherapy Planning in the Multi-Hospital/Multi-Trial-Center-Environment of Pediatric Oncology

Objective: Chemotherapy planning in pediatric oncology is complex and time-consuming. The correctness of the calculation according to state-of-the-art research is crucial for curing the child. Computer-assistance can be of great value. The objective of our research was to work out a meta-model of chemotherapy planning based on the Unified Modeling Language (UML). The meta-model is used for the development of an application system which serves as a knowledge-acquisition tool for chemotherapy protocols in pediatric oncology as well as for providing protocol-based care.

Methods: We applied evolutionary prototyping, software re-engineering techniques and grounded theory, a qualitative method in social research. We repeated the following steps several times over the years: Based on a requirements analysis (i) a meta-model was developed or adapted, respectively (ii). The meta-model served as a basis for implementing evolutionary prototypes (iii). Further requirements were identified (i) from clinical use of the systems.

Results: We developed a comprehensive UML-based meta-model for chemotherapy planning in pediatric oncology (chemoMM). We implemented it and introduced evolutionary prototypes (CATIPO and DOSPO) in several medical centers. Systematic validation of the prototypes enabled us to derive a final meta-model which covers the requirements that have turned out to be necessary in clinical routine.

Conclusions: We have developed an application system that fits well into clinical routine of pediatric oncology in Germany. Validation results have shown that the implementation of the meta-model chemoMM can adequately support the knowledge acquisition process for protocol-based care.

Towards Clinical Bioinformatics: Advancing Genomic Medicine with Informatics Methods and Tools

Objectives: To summarize the challenges facing clinical applications in the light of growing research results in genomic medicine and bioinformatics.

Methods: Analysis of the contents of the Yearbook of Medical Informatics 2004 of the International Medical Informatics Association (IMIA).

Results: The Yearbook of Medical Informatics 2004 includes 32 articles selected from 22 peer-reviewed scientific journals. A special section on clinical bio-informatics highlights recent developments in this field. Several guest editors review the promises and limitations of available methods and resources from biomedical informatics that are relevant to clinical medicine. Integrated data and knowledge resources are generally regarded to be central and key issues for clinical bioinformatics. Further review papers deal with public health implications of bioinformatics, knowledge management and trends in health care education. The Yearbook includes for the first time a section on the history of medical informatics, where the significant impact of the Reisensburg protocol 1973 on international health and medical informatics education is examined.

Conclusions: Close collaboration between bio-informatics and medical informatics researchers can contribute to new insights in genomic medicine and contribute towards the more efficient and effective use of genomic data to advance clinical care.

On Educating about Medical Data Management

Objectives: To summarize background, challenges, objectives, and methods for the usability of patient data, in particular with respect to their multiple use, and to point out how to lecture medical data management.

Methods: Analyzing the literature, providing an example based on Simpson’s paradox and summarizing research and education in the field of medical data management, respectively health information management (in German: Medizinische Dokumentation).

Results: For the multiple use of patient data, three main categories of use can be identified: patientoriented (or casuistic) analysis, patient-group reporting, and analysis for clinical studies. A so-called documentation protocol, related to study plans in clinical trials, supports the multiple use of data from the electronic health record in order to obtain valid, interpretable results. Lectures on medical data management may contain modules on introduction, basic concepts of clinical data management and coding systems, important medical coding systems (e.g. ICD, SNOMED, TNM, UMLS), typical medical documentation systems (e.g. on patient records, clinical and epidemiological registers), utilization of clinical data management systems, planning of medical coding systems and of clinical data management systems, hospital information systems and the electronic patient record, and on data management in clinical studies.

Conclusion: Usability, the ultimate goal of recording and managing patient data, requires, besides technical considerations, in addition appropriate methodology on medical data management, especially if data is intended to be used for multiple purposes, e.g. for patient care and quality management and clinical research. Medical data management should be taught in health and biomedical informatics programs.

Challenges in the Evolution of the Medical Informatics Program at Heidelberg/Heilbronn (Germany)

Objective: Health and medical informatics (HMI) is an evolving discipline. Therefore, evolving educational programs in HMI have to take a variety of requirements into account. The aim of this paper is to analyze these requirements and to compare them with the medical informatics program Heidelberg/Heilbronn, Germany.

Methods: Systematic analysis of the IMIA recommendations on educating HMI, the Bologna declaration, current technological and health care developments and the results of graduates surveys.

Results: The latest revision of the Heidelberg/ Heilbronn medical informatics program not only takes current developments into account but also realizes the IMIA recommendations, the Bologna declaration and graduates’ data and feedback obtained in structured surveys. The topics bioinformatics, IT security and tele-medicine were strengthened, taking major research and application trends into account. The program has been transformed into a consecutive bachelor/master program. It qualifies its graduates to work in the field of medical informatics as well as in informatics.

Conclusions: Medical informatics is a very broad field. Programs have to make concessions to scope: It is not possible to provide profound knowledge and skills in computer science and also teach a variety of application areas like bioinformatics, public health informatics and clinical informatics in depth within one medical informatics program. Many graduate programs in various nations concentrate on providing HMI skills to health care professionals.

Using data from ambient assisted living and smart homes in electronic health records

INTRODUCTION

This editorial is part of the Focus Theme of Methods of Information in Medicine on "Using Data from Ambient Assisted Living and Smart Homes in Electronic Health Records".

BACKGROUND

To increase efficiency in the health care of the future, data from innovative technology like it is used for ambient assisted living (AAL) or smart homes should be available for individual health decisions. Integrating and aggregating data from different medical devices and health records enables a comprehensive view on health data.

OBJECTIVES

The objective of this paper is to present examples of the state of the art in research on information management that leads to a sustainable use and long-term storage of health data provided by innovative assistive technologies in daily living.

RESULTS

Current research deals with the perceived usefulness of sensor data, the participatory design of visual displays for presenting monitoring data, and communication architectures for integrating sensor data from home health care environments with health care providers either via a regional health record bank or via a telemedical center.

CONCLUSIONS

Integrating data from AAL systems and smart homes with data from electronic patient or health records is still in an early stage. Several projects are in an advanced conceptual phase, some of them exploring feasibility with the help of prototypes. General comprehensive solutions are hardly available and should become a major issue of medical informatics research in the near future.

A Generic Data Harmonization Process for Cross-linked Research and Network Interaction. Construction and Application for the Lung Cancer Phenotype Database of the German Center for Lung Research

OBJECTIVE

Joint data analysis is a key requirement in medical research networks. Data are available in heterogeneous formats at each network partner and their harmonization is often rather complex. The objective of our paper is to provide a generic approach for the harmonization process in research networks. We applied the process when harmonizing data from three sites for the Lung Cancer Phenotype Database within the German Center for Lung Research.

METHODS

We developed a spreadsheet-based solution as tool to support the harmonization process for lung cancer data and a data integration procedure based on Talend Open Studio.

RESULTS

The harmonization process consists of eight steps describing a systematic approach for defining and reviewing source data elements and standardizing common data elements. The steps for defining common data elements and harmonizing them with local data definitions are repeated until consensus is reached. Application of this process for building the phenotype database led to a common basic data set on lung cancer with 285 structured parameters. The Lung Cancer Phenotype Database was realized as an i2b2 research data warehouse.

CONCLUSION

Data harmonization is a challenging task requiring informatics skills as well as domain knowledge. Our approach facilitates data harmonization by providing guidance through a uniform process that can be applied in a wide range of projects.

Potential and requirements of IT for ambient assisted living technologies. Results of a Delphi study

OBJECTIVES

Ambient Assisted Living (AAL) technologies are developed to enable elderly to live independently and safely. Innovative information technology (IT) can interconnect personal devices and offer suitable user interfaces. Often dedicated solutions are developed for particular projects. The aim of our research was to identify major IT challenges for AAL to enable generic and sustainable solutions.

METHODS

Delphi Survey. An online questionnaire was sent to 1800 members of the German Innovation Partnership AAL. The first round was qualitative to collect statements. Statements were reduced to items by qualitative content analysis. Items were assessed in the following two rounds by a 5-point Likert-scale. Quantitative analyses for second and third round: descriptive statistics, factor analysis and ANOVA.

RESULTS

RESPONDENTS

81 in first, 173 in second and 70 in third round. All items got a rather high assessment. Medical issues were rated as having a very high potential. Items related to user-friendliness were regarded as most important requirements. Common requirements to all AAL-solutions are reliability, robustness, availability, data security, data privacy, legal issues, ethical requirements, easy configuration. The complete list of requirements can be used as framework for customizing future AAL projects.

CONCLUSIONS

A wide variety of IT issues have been assessed important for AAL. The extensive list of requirements makes obvious that it is not efficient to develop dedicated solutions for individual projects but to provide generic methods and reusable components. Experiences and results from medical informatics research can be used to advance AAL solutions (e.g. eHealth and knowledge-based approaches).

Biomedical informatics--a confluence of disciplines?

BACKGROUND

Biomedical informatics is a broad discipline that borrows many methods and techniques from other disciplines.

OBJECTIVE

To reflect a) on the character of biomedical informatics and to determine whether it is multi-disciplinary or inter-disciplinary; b) on the question whether biomedical informatics is more than the sum of its supporting disciplines and c) on the position of biomedical informatics with respect to related disciplines.

METHOD

Inviting an international group of experts in biomedical informatics and related disciplines on the occasion of the 50th anniversary of Methods of Information in Medicine to present their viewpoints.

RESULTS AND CONCLUSIONS

This paper contains the reflections of a number of the invited experts on the character of biomedical informatics. Most of the authors agree that biomedical informatics is an interdisciplinary field of study where researchers with different scientific backgrounds alone or in combination carry out research. Biomedical informatics is a very broad scientific field and still expanding, yet comprised of a constructive aspect (designing and building systems). One author expressed that the essence of biomedical informatics, as opposed to related disciplines, lies in the modelling of the biomedical content. Interdisciplinarity also has consequences for education. Maintaining rigid disciplinary structures does not allow for sufficient adaptability to capitalize on important trends nor to leverage the influences these trends may have on biomedical informatics. It is therefore important for students to become aware of research findings in related disciplines. In this respect, it was also noted that the fact that many scientific fields use different languages and that the research findings are stored in separate bibliographic databases makes it possible that potentially connected findings will never be linked, despite the fact that these findings were published. Bridges between the sciences are needed for the success of biomedical informatics.

Usage and usability of standard operating procedures (SOPs) among the coordination centers for clinical trials (KKS)

OBJECTIVES

With Standard Operating Procedures (SOPs) the conduction of clinical trials should be standardized so that the results are comparable and traceable. This aim can only be reached if the staff of clinical trials really uses the SOPs. Therefore, we conducted a survey to explore the use and usability of SOPs in clinical trials and to identify problems for their handling.

METHOD

Standardized, validated questionnaire among the staff of all 12 coordination centers for clinical trials in Germany (n = 238), anonymous, descriptive analyses

RESULTS

A return rate of 58.8% was reached. When having questions about the daily work 18.4% more likely ask a colleague than read the corresponding SOP (13.8%). For the relevance of SOPs 16.9% of the staff regard less than 10% of SOPs as relevant for them. Exclusively working with electronic SOPs are 4%.

CONCLUSIONS

The results of the survey indicate that improvements for the handling of SOPs are necessary. They could be used to design a computer-based information retrieval system for SOPs to increase the ease-of-use and usefulness of SOPs in clinical trials.

On educating about medical data management - the other side of the electronic health record

OBJECTIVES

To summarize background, challenges, objectives, and methods for the usability of patient data, in particular with respect to their multiple use, and to point out how to lecture medical data management.

METHODS

Analyzing the literature, providing an example based on Simpson's paradox and summarizing research and education in the field of medical data management, respectively health information management (in German: Medizinische Dokumentation).

RESULTS

For the multiple use of patient data, three main categories of use can be identified: patient-oriented (or casuistic) analysis, patient-group reporting, and analysis for clinical studies. A so-called documentation protocol, related to study plans in clinical trials, supports the multiple use of data from the electronic health record in order to obtain valid, interpretable results. Lectures on medical data management may contain modules on introduction, basic concepts of clinical data management and coding systems, important medical coding systems (e.g. ICD, SNOMED, TNM, UMLS), typical medical documentation systems (e.g. on patient records, clinical and epidemiological registers), utilization of clinical data management systems, planning of medical coding systems and of clinical data management systems, hospital information systems and the electronic patient record, and on data management in clinical studies.

CONCLUSION

Usability, the ultimate goal of recording and managing patient data, requires, besides technical considerations, in addition appropriate methodology on medical data management, especially if data is intended to be used for multiple purposes, e.g. for patient care and quality management and clinical research. Medical data management should be taught in health and biomedical informatics programs.
