An experimental electronic medical-record system with multiple views on medical narratives.

In this article we describe a prototype electronic medical-record system that has been developed specifically to facilitate searching through medical narratives, as part of a preparatory study to the development of a medical workstation. This system contains a searching structure in which several views on the medical data are combined. We describe the structure of the database and the user-interface. A second design goal was to prepare the system for conducting research with respect to the use of the medical record. We address the kind of test designs the system can support and describe the research module that was implemented. We also describe a study we conducted with the system and report part of its results. We discuss the significance of this medical-record system compared to systems in the literature, some technical and functional problems encountered, and our future plans with the system.

A closer look at cueing effects in multiple-choice questions.

This study investigates the cueing effect occurring in multiple choice questions. Two parallel tests with matching contents were administered. By means of a computer program, examinees of different training levels and professional expertise were presented the same set of 35 cases (derived from patient problems in general practice) twice. The first time the cases were linked to open-ended questions; the second time they were linked to multiple choice questions. The examinees consisted of 75 medical students from three different years of training, 25 residents in training for general practice and 25 experienced general practitioners. Across groups, total test scores reflected a difference in mean scores on both formats, and a high inter-test correlation. Within each level of expertise, differences in mean scores and high correlations were also found. The data were further explored per group of examinees. Two types of cueing effects were found: positive cueing (examinees were cued towards the correct answer) and negative cueing (examinees were cued towards an incorrect answer). These effects were found at all levels of expertise and in almost all items. However, both effects decline with increasing level of expertise. Positive cueing mainly occurs in difficult items, whereas negative cueing mainly occurs in easy items.

Development, implementation and a first evaluation of a protocol processing system (ProtoVIEW).

In this contribution the protocol information system ProtoVIEW is presented. The system provides the necessary information to physicians about diagnostic procedures and therapies. It is implemented as a stand alone system. The design criteria are discussed and the results of a first evaluation presented. It appears that interns can easily find the required information with the help of the system. The time that they need for accessing the relevant information is relatively short (about 1 min). The users expressed the opinion that the system is easy to use and does support them in the management of their patients. On the basis of this evaluation and evaluations reported elsewhere it is concluded (a) that stand-alone protocol systems can support daily patient management in a positive way and (b) that the design criteria for a protocol information system as presented in this paper are useful for prospective protocol information system developers.
