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)
Late effects of treatment for childhood cancer on the thyroid axis are ascribed predominantly to radiotherapy. Whether chemotherapy has an additional detrimental effect is still unclear. Our aim was to evaluate this effect in young adult survivors of a broad spectrum of childhood cancers. The thyroid axis in 205 childhood cancer survivors was evaluated in(More)
