OBJECTIVE To synthesize the literature on clinical decision-support systems' (CDSS) impact on healthcare practitioner performance and patient outcomes. DESIGN Literature search on Medline, Embase, Inspec, Cinahl, Cochrane/Dare and analysis of high-quality systematic reviews (SRs) on CDSS in hospital settings. Two-stage inclusion procedure: (1) selection(More)
OBJECTIVE Usability evaluation is now widely recognized as critical to the success of interactive health care applications. However, the broad range of usability inspection and testing methods available may make it difficult to decide on a usability assessment plan. To guide novices in the human-computer interaction field, we provide an overview of the(More)
This paper discusses the preliminary results of a systematic review of the literature on applied usability studies of health information systems in the period 1990 to 2006. Abstracts were included when they described an evaluation of the usability of a health information system. To gain insight into usability methods applied and their properties we(More)
Clinical decision support systems (CDSSs) differ from other health information systems in their aim to directly influence the decision-making behaviour of healthcare professionals. As a result, CDSSs face additional challenges with respect to user acceptance. The objective of this study was to investigate subjective usability of a guideline-based CDSS for(More)
OBJECTIVES Clinical use of computer systems has been hampered by their poorly designed user interfaces. The objective of this study was to design a user interface for a pediatric oncologists' computerized patient record with great consideration of their working behavior and of human computer interfacing principles so as to contribute to oncologists'(More)
OBJECTIVES To assess the usability of an emerging POE system, OM/Lab, for the computer-supported ordering of laboratory tests. We were more specifically interested in the relation of the usability problems detected in the user testing sessions with the order behaviour in terms of efficiency and errors in ordering. METHODS A cognitive walkthrough of the(More)
OBJECTIVES To examine the impact of design aspects of computerized physician order entry (CPOE) systems for medication ordering on usability, physicians' workflow and on medication orders. METHODS We systematically searched PubMed, EMBASE and Ovid MEDLINE for articles published from 1986 to 2007. We also evaluated reference lists of reviews and relevant(More)
OBJECTIVES To study the effect of predefined order sets on the efficiency of computerized medication ordering, and to analyze the effect of different types of usability problems on ordering efficiency. METHODS Crossover study to comparing the efficiency of two methods of ordering (with and without use of predefined order sets) in a laboratory setting(More)
We report on a course for medical informatics students on hospital information systems, especially on its strategic information management. Starting as course at the Medical Informatics Program of the University of Heidelberg/University of Applied Sciences Heilbronn, it is now organized as international course in the framework of the International(More)
OBJECTIVE The rising incidence of type 2 diabetes mellitus (T2DM) induces severe challenges for the health care system. Our research group developed a web-based system named PANDIT that provides T2DM patients with insulin dosing advice using state of the art clinical decision support technology. The PANDIT interface resembles a glucose diary and provides(More)
