In this on-road experiment, drivers performed demanding cognitive tasks while driving in city traffic. All task interactions were carried out in hands-free mode so that the 21 drivers were not required to take their visual attention away from the road or to manually interact with a device inside the vehicle. Visual behavior and vehicle control were assessed(More)
The Lane Change Test (LCT) is an easy-to-implement, low-cost methodology for the evaluation of the distraction associated with performing in-vehicle tasks while driving (Mattes, 2003). In the present study, the LCT was used to assess driving performance when drivers completed navigation tasks using visual-manual or speech-based interfaces. Drivers performed(More)
OBJECTIVE The goal of this study was to assess the nature and frequency of interruptions during medication administration and the interruptions' effects on task efficiency to guide healthcare managers/executives in improving patient safety and staff productivity. BACKGROUND Interruptions have been identified as causal factors in medication administration(More)
OBJECTIVE Assess the impact of infusion pump technologies (traditional pump vs smart pump vs smart pump with barcode) on nurses' ability to safely administer intravenous medications. DESIGN Experimental study with a repeated measures design. SETTING High-fidelity simulated inpatient unit. RESULTS The nurses remedied 60% of "wrong drug" errors. This(More)
OBJECTIVE To determine what components of a checklist contribute to effective detection of medication errors at the bedside. DESIGN High-fidelity simulation study of outpatient chemotherapy administration. SETTING Usability laboratory. PARTICIPANTS Nurses from an outpatient chemotherapy unit, who used two different checklists to identify four(More)
With the advent of new technology in vehicles, drivers can access information in many different forms (email, address books, Web pages) and from many information sources (cell phones, PDAs, driver support systems). With these new information sources finding their way into cars comes increasing concern about the potential adverse effects resulting from(More)
BACKGROUND Nurses are frequently interrupted during medication verification and administration; however, few interventions exist to mitigate resulting errors, and the impact of these interventions on medication safety is poorly understood. OBJECTIVE The study objectives were to (A) assess the effects of interruptions on medication verification and(More)
PURPOSE Intensive care unit (ICU) nurses get interrupted frequently. Although interruptions take cognitive resources from a primary task and may hinder performance, they may also convey critical information. Effective management of interruptions in ICUs requires the understanding of interruption characteristics, the context in which interruption happens,(More)
Multifunction in-vehicle information systems are becoming increasingly prevalent in cars. These systems typically use a centrally located display and a single control device to carry out a variety of operations including navigation, communications, entertainment, and climate control. Advantages of these systems include: conservation of dashboard space,(More)
