"Evaluating Technology in Health Care: Testing the Usability of a Clinical Trial Query Tool Using Think Aloud Methods" Abstract: In the health care field, new technology is being constantly introduced to improve patient care, streamline medical record keeping, and increase clinicians’ access to information. Evaluators can play an important role in the development and improvement of new health technology by developing effective methods to evaluate its implementation and usability from the users’ point of view. In this paper, we discuss the evaluation of a clinical trial query tool (based on Harvard University’s Informatics for Integrating Biology and the Bedside-i2b2 tool) adapted by the University of California Davis Health System. To understand clinicians’ experiences using the tool, we developed an evaluation toolkit that included surveys, think alouds, and cursor movement analysis (through Camtasia Studio software). Focusing on the think aloud and cursor movement analysis, we discuss the opportunities and challenges these methods present. This project provides an example of both evaluating the use of technology and using technology in evaluation. #QualitativeMethods #usabilitystudy #2010Conference #IntegratingTechnologyintoEvaluation
