    7 years of experience using personal digital assistants (PDA) for psychometric diagnostics in 6000 inpatients and polyclinic patients
    (Mobile Computing in Medicine, Second Conference on Mobile Computing in Medicine, Workshop of the Project Group MoCoMed, GMDS-Fachbereich Medizinische Informatik & GI-Fachausschuss 4.7, 2002) Rose, M.; Walter, O. B.; Fliege, H.; Becker, J.; Hess, V.; Klapp, B.F.
    In clinical psychosomatics there is a need for adequate documentation of psychometric data both within the framework of individual diagnostics and in carespecific quality assurance. The data collection method should meet current psychometric standards, while at the same time allowing a fast and economical evaluation. In contrast to conventional methods using paper and pencil, computer-assisted testing offers considerable advantages in both regards. Using data collected from 6434 patients between the years of 1995 and 2002, we investigated what effects the complete conversion of a psychometric basis assessment to a mobile, computer-assisted method had in terms of acceptance, data structure, and economy. We implemented the following questionnaires, among others: the Center for Epidemiologic Studies-Depression (CES-D) Scale, the Giessen Complaint Inventory (Giessener Beschwerdebogen GBB), the Berlin Mood Questionnaire (Berliner Stimmungsfragebogen BSF), the State-Trait-Anxiety Inventory (STAI), the Short-Form 36 (SF-36), the WHOQOL-Bref, the Giessen Test (GTS), the Narcissism Inventory (NI), and parts of the Psychosomatic Basis Documentation (PsyBaDo). Based on our experience, we can conclude that 1. testing by means of mobile PDA's enjoys a high rate of acceptance among patients, 2. the organization of data is considerably improved, which guarantees an immediate evaluation for clinical and scientific lines of questioning, 3. no significant alterations result in terms of the psychometric characteristics of the questionnaire, and 4. mobile computerized testing is two-thirds cheaper than conventional testing using paper and pencil.

    Accessing DICOM 2D/3D-image and waveform data on mobile devices
    (Mobile Computing in Medicine, Second Conference on Mobile Computing in Medicine, Workshop of the Project Group MoCoMed, GMDS-Fachbereich Medizinische Informatik & GI-Fachausschuss 4.7, 2002) Kroll, M.; Melzer, K.; Lipinski, H.-G.
    Displaying medical images and waveforms which are stored in the DICOM file format is no longer a task that can be performed on desktop pc's only. This article describes a feasibility study where we have developed a set of applications for viewing and even analysing DICOM image and waveform objects on mobile devices such as mobile phones or PDAs. In order to overcome the shortcomings, especially the computing power, of those devices we use a client/server solution that has been completely implemented using the Java Programming Language on the server and the c lient devices as well.

    Applicability of handheld computers in clinical information systems: Comparison of evaluation methods
    (Mobile Computing in Medicine, Second Conference on Mobile Computing in Medicine, Workshop of the Project Group MoCoMed, GMDS-Fachbereich Medizinische Informatik & GI-Fachausschuss 4.7, 2002) Christoph, K.; Bludau, H.-B.
    Although handheld computers are increasingly used in professional areas, an instrument for evaluating their applicability in different cases and scopes does not yet exist. There is an urgent need for standardised evaluation methods comprising handheld specific questions like mobility, different hardware (CE, Palm, Psion), different possibilities for data capture (keyboard versus pen), different displays, or individual combination of functionality, to highlight just a few important tasks. This paper consists of a description of common evaluation methods and their comparison. On this basis we present an extension of established instruments for evaluation, which was tested in clinical environment. Main focus is laid upon the ISO 9241 Part 10 and the principles of organisation described therein: self-descriptiveness, controllability, conformity with user expectations, error tolerance, suitability for individualisation and suitability for learning. These standards are integrated into different questionnaires (e.g., IsoMetrics, Iso- Norm), which are the basis for further development of the adoption to mobile computer evaluation. We give an overview on usability of questionnaires based on ISO 9241 Part 10, together with our extension in the part of the handheld-specific questions. The results permit a first estimation about the applicability and functionality of handheld computers in a clinical environment. We evaluate if such an extension of the ISO-based questionnaire is appropriate for describing the full applicability of handheld computers.

    Design, deployment and evaluation of a clinical information system which uses mobile computers and workstations
    (Mobile Computing in Medicine, Second Conference on Mobile Computing in Medicine, Workshop of the Project Group MoCoMed, GMDS-Fachbereich Medizinische Informatik & GI-Fachausschuss 4.7, 2002) Urban, M.; Kunath, M.
    Modern computer technologies, such as telemedicine, have been successfully introduced in medical practice. However, whereas in an office-like environment, an integration of computers is uncomplicated, it is quite difficult to accommodate computers in an environment, where medical staff working at the point of care needs to be highly mobile. In this environment, computers need to be highly mobile, too, and have to operate in many different situation. In this paper we study a prototype of a clinical information system (CIS). We focus on the support of mobility in a CIS in order to bolster cooperation and communication between medical personnel. We examine possible mobile computer technologies for a CIS and we develop a taxonomy of graphical elements for input of medical data (we use these elements in the prototype CIS). The use of this prototype was carried out under the conditions of a field study on a real hospital ward. The results of the field study and the evaluation are presented.

    EMIKA – Real-time controlled mobile information systems in healthcare applications
    (Mobile Computing in Medicine, Second Conference on Mobile Computing in Medicine, Workshop of the Project Group MoCoMed, GMDS-Fachbereich Medizinische Informatik & GI-Fachausschuss 4.7, 2002) Sackmann, S.; Eymann, T.; Müller, G.
    This paper presents an approach to control and management of real-time hospital patient logistics by decentralized coordination in a time-critical application environment. Responsible for coordination are software agents implemented on mobile, spontaneously network end-user devices like PDAs or RFID chips. The coordination is achieved by real-time bilateral negotiation, location awareness and exception handling. The application scenario of the EMIKA project is the patient logistics of the University Hospital Freiburg in the areas of transport service and radiology.

    From semi-mobile to mobile work? Possibilities and constraints for hand-held computer use in home health care
    (Mobile Computing in Medicine, Second Conference on Mobile Computing in Medicine, Workshop of the Project Group MoCoMed, GMDS-Fachbereich Medizinische Informatik & GI-Fachausschuss 4.7, 2002) Hughes, T.; Karsten, H.; Konttila, J.; Järvi, S.
    This paper discusses the possibilities and constraints for using mobile computing in home health care by examining the work of home health care nurses in the city of Turku, located in the southwestern part of Finland. Home health care differs from other forms of health care by being 'semi-mobile'. Approximately half of a nurse's day is spent making visits to the homes of patients and the other half is spent at a shared office. While in the office, the nurses, among other things, enter information into a patient information system and communicate with other nurses present. By following the work of nurses, we found several possible applications for mobile or hand held devices. Mobile access to a variety of information sources and improved communication possibilities seemed valuable and appeared to offer possibilities for both improving the quality of the nurses' work and allowing the nurses to spend more time with their patients. In our study, however, we also found that the special nature of the work of home health care nurses sets many important constraints which must be taken into consideration before the work of home health care nurses can become truly mobile. Among other things, we found that the visits the nurses make to the office are more than just mandatory visits required for entering patient information and reporting the day's events to other nurses.

    Handheld-based data collection in a highly distributed clinical study (PMS)
    (Mobile Computing in Medicine, Second Conference on Mobile Computing in Medicine, Workshop of the Project Group MoCoMed, GMDS-Fachbereich Medizinische Informatik & GI-Fachausschuss 4.7, 2002) Antwerpes, F.; Weber, R.
    Electronic Data Capturing offers a significantly higher ad-hoc quality of study data at the time of entry, which is specifically important for post-marketing type studies where resources for subsequent data cleaning are limited. Internet-based tools provide a good solution to these scenarios as typically large numbers of centres and/or doctors are involved. But while the deployment of Internet-based (online) studies on existing computer equipment is relatively easy, participants might find it sometimes difficult to integrate the electronic documentation effort into the clinical practice. This might be due to limited availability of Internet access, the location of the computers, security concerns etc. The presented case study shows how the introduction of handheld computers can help to overcome these issues and provide for added flexibility and ease of use. Furthermore, actual data regarding the penetration of mobile devices in the medical community in Germany is discussed to give an outlook of the future potential for mobile studies.

    @HOME: A modular telemedicine system
    (Mobile Computing in Medicine, Second Conference on Mobile Computing in Medicine, Workshop of the Project Group MoCoMed, GMDS-Fachbereich Medizinische Informatik & GI-Fachausschuss 4.7, 2002) Sachpazidis, I.
    In that paper we will describe a system for remotely monitoring of patients at home from the doctors at the hospital. In general, the @Home [AtH02] system can measure, collect, analyze and record health care data at a patient's home and then subsequently send these data to the hospital using the global system for mobile communications (GSM) or PSTN telephone line. The paper is organized as follows: In section 1, a brief introduction of the @home project is exposed. In section 2, the overall architecture of the system is shown. Finally, the paper concludes in section 3, stating the clinical trials and the benefits of the project.

    Key factors for personal health monitoring and diagnosis device
    (Mobile Computing in Medicine, Second Conference on Mobile Computing in Medicine, Workshop of the Project Group MoCoMed, GMDS-Fachbereich Medizinische Informatik & GI-Fachausschuss 4.7, 2002) Schwaibold, M.; Gmelin, M.; Wagner, G. von; Schöchlin, J.; Bolz, A.
    The current common goal in medical information technology today is the design and implementation of telemedicine solutions, which provide chronically ill patients with mobile services that enhance their quality of life, and support and optimize their treatment in case of emergency. Several projects being worked on by FZI and its partners will form a basis for a novel, individual and widespread health monitoring system, which can provide patients with 24h monitoring of their relevant physiological parameters, and therefore optimize their medical treatment and could possibly be life-saving thanks to the enhanced emergency management. In order to be able to build a successful platform for a wide range of medical applications in practice, key factors have been identified which will be introduced in this paper: micro-technological sensors, which are to be used in mobile applications, modularity, a wireless communication network, local intelligence in the form of a powerful mobile information unit, connection to a global network and a conclusive system design for improving the efficiency of health care-related procedures.

    Lessons learned from 16 years usage of mobile computers in clinical trials
    (Mobile Computing in Medicine, Second Conference on Mobile Computing in Medicine, Workshop of the Project Group MoCoMed, GMDS-Fachbereich Medizinische Informatik & GI-Fachausschuss 4.7, 2002) Koop, A.
    For more than 16 years, mobile computers have been supporting the implementation of clinical trials. A review of 28 articles out of more than 100 clinical trials in which mobile computers have been used elaborates on the advantages and problems of this technology. A comprehensive overview of the various technologies as used in different settings is given, and then the methodology of using mobile devices in comparison to traditional methods is discussed. The considerations that need to be made and things to be avoided in order to conduct a successful clinical trial with mobile tools are listed in detail. This survey leads to the conclusion that mobile devices are very useful in most cases, especially when design and software validation aspects have been taken into account. Furthermore information is given about software validation aspects that are unique to the field of clinical trials.
