The purpose of this study is four-fold. First, the hospitals' current level of computerized physician order entry (CPOE) adoption is reported; second, internal and external influence factors' roles in determining CPOE adoption rates are described; third, the future diffusion rate of CPOE systems in US hospitals is empirically predicted; finally, the current technology's state-of-the-art is assessed. ⋯ The promise of improved quality of care through medication error reductions and significant cost controls prompted the Institute of Medicine to call for universal CPOE adoption by 1999. However, the CPOE products available as of 2006 represent only a 'second generation technology', characterized by many limitations. Without increased external and internal pressures, such CPOE systems are unlikely to achieve full diffusion in US hospitals in a timely manner. Alternatively, developing a new generation of CPOE technology that is more 'user-friendly' and easily integrated into hospitals' legacy systems may be a more expedient approach to achieving widespread adoption.

This article describes the evaluation of a prototype speech-input interface to an anaesthesia patient record, conducted in a full-scale anaesthesia simulator involving six doctor-nurse anaesthetist teams. ⋯ A vocal interface leads to shorter time between the events to be registered and the actual registration in the electronic anaesthesia record; therefore, this type of interface would likely lead to greater accuracy of items recorded and a reduction of mental workload associated with memorization of events to be registered, especially during time constrained situations. At the same time, current speech recognition technology and speech interfaces require user training and user dedication if a speech interface is to be used successfully.

This paper reviews the research literature on electronic health record (EHR) systems. The aim is to find out (1) how electronic health records are defined, (2) how the structure of these records is described, (3) in what contexts EHRs are used, (4) who has access to EHRs, (5) which data components of the EHRs are used and studied, (6) what is the purpose of research in this field, (7) what methods of data collection have been used in the studies reviewed and (8) what are the results of these studies. ⋯ Studies focusing on the content of EHRs are needed, especially studies of nursing documentation or patient self-documentation. One future research area is to compare the documentation of different health care professionals with the core information about EHRs which has been determined in national health projects. The challenge for ongoing national health record projects around the world is to take into account all the different types of EHRs and the needs and requirements of different health care professionals and consumers in the development of EHRs. A further challenge is the use of international terminologies in order to achieve semantic interoperability.

The emergency department has been characterized as interrupt-driven. Government agencies and patient safety organizations recognize that interruptions contribute to medical errors. The purpose of this study was to observe, record, and contextualize activities and interruptions experienced by physicians and Registered Nurses (RNs) working in a Level One Trauma Center. ⋯ This research provides an enhanced understanding of interruptions in workflow in the ED, the identification of work constraints, and the need to develop interventions to manage interruptions. It is crucial that interruptions be delivered in such a way that there is minimal negative impact on performance. The significance and importance of the interruption must always be weighed against the negative impact that it has on smooth, efficient workflow.

Children with acute abdominal pain (AP) are frequently assessed in the Emergency Department (ED). Though the majority of patients have benign causes, uncertainty during the physician's initial assessment may result in unnecessary tests and prolonged observation before a definitive disposition decision can be made. A rule-based mobile clinical decision support system, Mobile Emergency Triage-Abdominal Pain (MET-AP), has been developed to recommend an appropriate triage plan (discharge, consult surgery or observe/investigate) early in the ED visit, with the goal of promoting ED efficiencies and improved patient outcomes. ⋯ MET-AP shows promise in recommending the correct triage plan with similar overall accuracy to experienced pediatric EPs, but requires further research to improve accuracy and safety. MET-AP can be used on all pediatric ED patients with AP and is capable of producing a triage plan recommendation without requiring a complete set of patient information.
