Distributed Cognition Artifacts on Clinical Research Data Collection Forms
Medical record abstraction, a primary mode of data collection in secondary data use, is associated with high error rates. Cognitive factors have not been studied as a possible explanation for medical record abstraction errors. We employed the theory of distributed representation and representational analysis to systematically evaluate cognitive demands in medical record abstraction and the exte...
متن کاملData standards for clinical research data collection forms: current status and challenges
Case report forms (CRFs) are used for structured-data collection in clinical research studies. Existing CRF-related standards encompass structural features of forms and data items, content standards, and specifications for using terminologies. This paper reviews existing standards and discusses their current limitations. Because clinical research is highly protocol-specific, forms-development p...
متن کاملDesign of forms for clinical trials (1).
If one accepts that the design of the forms used in clinical trials is important, and that there is behavioural research which might be drawn on to improve their design, the question now is how can such improvements be achieved. One mistaken view is to hope that when behavioural scientists have explored all the many facets of form design there will arise a set of guidelines that guarantee succe...
متن کاملA comparative study of mobile electronic data entry systems for clinical trials data collection
PURPOSE To determine the speed, accuracy, ease of use, and user satisfaction of various electronic data entry platforms for use in the collection of mammography clinical trials data. METHOD AND MATERIALS Four electronic data entry platforms were tested: standalone personal digital assistant (PDA), Tablet PC, digitizer Tablet/PDA Hybrid (DTP Hybrid), and digital pen (d-pen). Standard paper dat...
متن کاملComparison of two data collection processes in clinical studies: electronic and paper case report forms
BACKGROUND Electronic Case Report Forms (eCRFs) are increasingly chosen by investigators and sponsors of clinical research instead of the traditional pen-and-paper data collection (pCRFs). Previous studies suggested that eCRFs avoided mistakes, shortened the duration of clinical studies and reduced data collection costs. METHODS Our objectives were to describe and contrast both objective and ...
