Mechanical ventilators are designed to generate alarms when patients become disconnected or experience other critical ventilator events. However, these alarms can blend in with other accustomed sounds of the intensive care unit. Ventilator alarms that go unnoticed for extended periods of time often result in permanent patient harm or death. We developed a system to monitor critical ventilator events through our existing hospital network. Whenever an event is identified, the [...]

This paper describes an institutional approach taken to build a primary care reference portal. The objective for the site is to make access to and use of clinical reference faster and easier and to facilitate the use of evidence-based answers in daily practice. Reference objects were selected and metadata applied to a core set of sources. Metadata were used to search, sort, and filter results and to define deep-linked queries [...]

Unintended consequences of computerized patient care system interventions may increase resource use, foster clinical errors, and reduce users' confidence.

To describe medical students' attitudes toward placing orders during training, and the effect of computerized provider order entry (CPOE) on their learning experiences.

Authors evaluated whether displaying context sensitive links to infrequently accessed educational materials and patient information via the user interface of an inpatient computerized care provider order entry (CPOE) system would affect access rates to the materials.

The aim of this study was to evaluate the impact of introducing health information technology (HIT) on physician-patient interactions during outpatient visits.

A commercial rule base (Cerner Multum) was used to identify medication orders exceeding recommended dosage limits at five hospitals within BJC HealthCare, an integrated health care system. During initial testing, clinical pharmacists determined that there was an excessive number of nuisance and clinically insignificant alerts, with an overall alert rate of 9.2%. A method for customizing the commercial rule base was implemented to increase rule specificity for problematic rules. The [...]

This study assessed the effect of a handheld computer-based decision support system (DSS) on antibiotic use and patient outcomes in a critical care unit.

To determine whether natural language processing (NLP) can effectively detect adverse events defined in the New York Patient Occurrence Reporting and Tracking System (NYPORTS) using discharge summaries.

The use of icons and other graphical components in user interfaces has become nearly ubiquitous. The interpretation of such icons is based on the assumption that different users perceive the shapes similarly. At the most basic level, different users must agree on which shapes are similar and which are different. If this similarity can be measured, it may be usable as the basis to design better icons.
