BACKGROUND In response to inherent inadequacies in health information technologies, clinicians create their own tools for managing their information needs. Little is known about these clinician-designed information tools. With greater appreciation for why clinicians resort to these tools, health information technology designers can develop systems that… (More)
Managers of operating rooms (ORs) and of units upstream (e.g., ambulatory surgery) and downstream (e.g., intensive care and post-anesthesia care) of the OR require real-time information about OR occupancy. Which ORs are in use, and when will each ongoing operation end? This information is used to make decisions about how to assign staff, when to prepare… (More)
Multi-disciplinary rounds are a forum for communication and sense-making, and they play a critical role in intensive care to ensure care coordination across specialties and providers. Increased availability of clinical information through computers has made it possible to provide support during rounds. We conducted an observation study to determine ways in… (More)
Permutation entropy is computationally efficient, robust to noise, and effective to measure complexity. We used this technique to quantify the complexity of continuous vital signs recorded from patients with traumatic brain injury (TBI). Using permutation entropy calculated from early vital signs (initial 10∼20% of patient hospital stay time), we built… (More)
This paper presents an ongoing observational study to explore a "front-stage-back-stage" model of information processes during group discussions (multidiscipli-nary rounds) in the pediatric intensive care unit (PICU) of an academic medical center. Participants were observed to collaborate on "front-stage" processes of case presentation, discussion of… (More)
We developed a set of visualization techniques to portray multiple threads or trajectories of events and activities to provide awareness support. Visualizing the historical and projected temporal patterns of trajectories may provide support to collaborating workers and promote anticipatory behaviors.
