In preparing the work discount 3mg stromectol with amex, the contributors were able to profit from the experience and insights collected and reported by many leading clinical researchers in the field generic stromectol 3 mg with visa. What are the key objectives, the challenges, and the corresponding options for study design? What should the architecture of diagnostic research look like to provide us with an appropriate research strategy, yielding the clinical information we are looking for, with a minimum burden for study patients and an efficient use of resources? Second, important design features for studying the accuracy and clinical impact of diagnostic tests and procedures are dealt with in more detail, addressing the cross-sectional study, the randomised trial, and the before–after study. In addition, it is shown that the impact of diagnostic tests varies with different clinical settings and target populations, and indications are given as how to ensure that estimates of test accuracy will travel and be transferable to other settings. Also, for clinical diagnostic studies, an overview of the most important data-analytic issues is presented, from simple two by two tables to multiple logistic regression analysis. Nowadays, for both clinical investigators and readers of research articles, it is not enough to understand the methodology of original clinical studies. They must also know more about the techniques to summarise and synthesise results from various clinical studies on a similar topic. Guidelines for diagnostic systematic reviews and meta-analysis are therefore presented. Learning from accumulated clinical experience and the application of diagnostic knowledge in practice has much in common with retrieving and selecting information from clinical databases. Accordingly, diagnostic decision support using information and communication technology (ICT) is addressed as an increasingly important domain for clinical practice, research, and education. Furthermore, as clinical research results can only be successfully incorporated into diagnostic decision making if the way clinicians tend to solve medical problems is taken into account, an overview of the domain of clinical problem solving is given. Eventually, we have to recognise that improving test use in daily care needs more than clinical research, and presenting guidelines and other supportive materials.
