Discovering relationships between health system performance and clinicians interaction with their work environments (patients, computers, equipment) provides evidence for re-design. Analyzing data from health information technology, real-time locating systems, and observation facilitates in-depth investigations of these interactions. In this context, we have performed human factors studies of clinician situation awareness, workload, and task analyses.
