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)
BACKGROUND We asked whether continuous intracranial pressure (ICP) monitoring data could provide objective measures of the degree and timing of intracranial hypertension (ICH) in the first week of neurotrauma critical care and whether such data could be linked to outcome. METHODS We enrolled adult (>17 years old) patients admitted to our Level I trauma(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)
We developed an algorithm for processing networked vital signs (VS) to remotely identify in real-time when a patient enters and leaves a given operating room (OR). The algorithm addresses two types of mismatches between OR occupancy and VS: a patient is in the OR but no VS are available (e.g., patient is being hooked up), and no patient is in the OR but(More)
Calculation of integer heart rate variability (HRVi) permits monitoring over extended periods. We asked whether continuous monitoring of HRVi or integer pulse pressure (PP) variability (PPVi) could predict intracranial hypertension, defined as ICP >20 mm Hg, cerebral hypoperfusion, defined as CPP<60 mm Hg, mortality or functional outcome after severe(More)
