    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.

    Patient empowerment and visualisation 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) Enzenhofer, M.; Komm, N.; Pauli, T.; Tran-Huu, M.-H.; Bludau, H.-B.
    Improved potentiality using multimedia components (audio, video, threedimensional pictures and interactive tools) as well as the growing desire of patients to receive more information leads to a widespread introduction of patient information systems. In co-operation with the "Wissenschaftliches Institut der Praxisärzte", Heidelberg we developed a tool to explain medical facts with twoand three dimensional pictures. In contrast to common web based information systems the tool is used by the physician itself to explain the medical content. The investigation will be carried out on a group of 50 patients from 2 different wards. Participants need a Karnofsky-Index of 70 points minimum. In a randomly process patient will be allocated to either a group which receive standardised information supported by the picture material or just a standardised consent talk. Detailed information is given about the indication, the probable complications and the details of the forthcoming procedures (coronary catheters or endoscopic procedures). The procedure takes place one day after the conversation between the physician and the patient. We conduct a prospective, randomised investigation using a tool called "Dr. Topf's Patienteninformationssystem" which has been designed to supplement the clarification of facts. A sample of 5 pictures maximum is presented on a sub-notebook. The computerised animation is limited to 5 minutes. Participants of the control group are informed with support of the common informative pamphlet only. An analysis of the time required is being performed. Short after the conversation between physician and patient, the patient is asked to personally assess the quality of the consent talk. 3 days later we check the evidence of the visualised approach using a formalised questionnaire (standard of knowledge). 10 multiple-choice questions, been taken from students assessment questionnaire and adapted to patient knowledge level, apply to the contents of the happened conversation.

    Use of electronic diaries within treatment of obesity and binge eating disorder: First experiences
    (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) Quenter, A.; Bludau, H.-B.; Friedrich, H.-C.; Schild, S.; Riepe, T.; Zipfel, S.
    After initial use for treatment-documentation within the scope of follow-up studies, electronic diaries are increasingly implemented in clinical settings. Particularly, diaries seem to fit very well in areas where "paper and pencil-diaries" yet constitute well established elements of symptom-focussed treatment settings, including a detailed description and analysis of problem behaviour. This e.g. applies to treatment of eating disorders like anorexia nervosa, bulimia nervosa or binge eating disorder (BED). BED is characterised by ingestion of a large amount of food in a discrete period of time, accompanied by a sense of loss of control. BED in particular appears to be predisposed for the use of electronic diaries: By the mean of self-observation based on diary recording, information about triggers of problem behaviour, thoughts, somatic symptoms, and feelings experienced during a binge, as well as patient's reactions in a detailed manner may be assessed. Therefore, as a therapeutic mean, electronic diaries are fostering taking-over of self-responsibility and thus, will raise treatment motivation. Especially when binge eating and loss of control occur, the use of diaries enhances self-control and self-regulation. Electronic diaries realised on handheld-computers (Palm 100m) are used within the scope of an intervention study realised by the Dept. of General Internal and Psychosomatic Medicine of the University of Heidelberg, focussing on treatment of obese patients with binge eating disorder. Purpose of the study is the registration of therapeutic relevant information as well as the assessment of progression within a multimodal, out-patient group therapy. First experiences demonstrate the feasibility of mobile computing systems even with elder out-patients with no or little technical knowledge. However, implementation of the system requires focussing particularly on technical aspects. Limitations which may result from insertion of innovative technical equipment (particularly, a susceptibility to electronic problems and maybe resulting in restrictions of data) should be considerated in an adequate manner during scheduling.
