The study experimentally tested the relationship between visual attention and comprehension of a TV program. 72 5-year-old children watched a 40-min version of the TV program "Sesame Street." Half the children viewed the program in the presence of a variety of toys and half viewed without toys. The children were then tested for their comprehension of the(More)
STUDY OBJECTIVE The objective of this investigation is to determine time-dependent workload patterns for emergency department (ED) physician teams across work shifts. A secondary aim was to demonstrate how ED demand patterns and the timing of shift changes influence the balance of workload among a physician team. METHODS Operational measurements of an(More)
BACKGROUND As the demands on the emergency medicine (EM) system continue to increase, improvements in the organization of work and the access to timely clinical and system information will be required for providers to manage their workload in a safe and efficient manner. Information technology (IT) solutions are beginning to find their place in the(More)
BACKGROUND We developed a practical influenza forecast model based on real-time, geographically focused, and easy to access data, designed to provide individual medical centers with advanced warning of the expected number of influenza cases, thus allowing for sufficient time to implement interventions. Secondly, we evaluated the effects of incorporating a(More)
BACKGROUND  Google Flu Trends (GFT) is a novel Internet-based influenza surveillance system that uses search engine query data to estimate influenza activity and is available in near real time. This study assesses the temporal correlation of city GFT data to cases of influenza and standard crowding indices from an inner-city emergency department (ED). (More)
OBJECTIVE The primary objective of this study was to create a methodology for measuring transient levels of physician workload in a live emergency department (ED) environment. BACKGROUND Characterizing, defining, and measuring aspects of this interrupt-driven work environment represent the preliminary steps in addressing impending issues concerning ED(More)
OBJECTIVE To develop a model to produce real-time, updated forecasts of patients' intensive care unit length of stay using naturally generated provider orders. The model was designed to be integrated within a computerized decision support system to improve patient flow management. DESIGN Retrospective cohort study. SETTING Twenty-six bed pediatric(More)
OBJECTIVE Emergency department crowding threatens quality and access to health care, and a method of accurately forecasting near-future crowding should enable novel ways to alleviate the problem. The authors sought to implement and validate the previously developed ForecastED discrete event simulation for real-time forecasting of emergency department(More)
The ability of 3-, 4-, and 5-year-old children to correctly identify videotaped TV segments as programs and commercials was examined. While this ability improved with age, responding was above chance for each age group. The children used both auditory and visual cues in making correct identifications. The results indicate that, when a task requiring minimal(More)
BACKGROUND Patient safety and emergency department (ED) functionality are compromised when inefficient coordination between hospital departments impedes ED patients' access to inpatient cardiac care. The objective of this study was to determine how bed demand from competing cardiology admission sources affects ED patients' access to inpatient cardiac care.(More)
