Fatigue assessment in the field: validation of a hand-held electronic psychomotor vigilance task.

INTRODUCTION: In recent years, there has been an increasing need for a reliable and practical tool for assessing fatigue-related impairment in the field. This study investigated the sensitivity of one potential tool, a 5-min version of the psychomotor vigilance task (PVT) specifically designed for use on personal digital assistants (PDA), to 28 h of sustained wakefulness. METHODS: There were 15 participants who slept in the laboratory overnight then remained awake from 08:00 (Day 1) to 12:00 (Day 2). During every second hour, they completed a 10-min PVT, a sustained attention task that is sensitive to the effects of sleep loss and fatigue, and a 5-min PDA-PVT. RESULTS: While performance on both tasks significantly varied as a function of hours of wakefulness, responses on the PDA-PVT were typically slower than on the PVT. When performance scores were standardized, the negative impact of increasing hours of wakefulness on performance on the 5-min PDA-PVT and 10-min PVT did not significantly differ. DISCUSSION: The findings suggest that the 5-min PDA-PVT may provide a reasonable substitute for the 10-min PVT, particularly in circumstances where a shorter test is required and/or the standard PVT is not as practical.

Electronic nose shows promise for detecting early-stage lung cancer.

A simple, non-invasive screening test for lung cancer? Not yet, but investigators are excited about new evidence that signs of lung cancer can actually be picked up from breath samples. The hope is that a simple, inexpensive breath test may eventually hold the key to detecting lung cancer at an early, highly treatable stage.

Benefits and costs of integrating technology into undergraduate nursing programs.

Advances in technology over the last decade have resulted in increased opportunities for educators to become more innovative in classroom and clinical teaching. These innovations have allowed students and faculty to access essential clinical information at the point of care/need. By capitalizing on technologies such as personal digital assistants and course delivery shells, faculty and students have both portable and remote access to information that can guide practice and learning activities in clinical, classroom, and distance settings. For instance, a student can use a personal digital assistant to research a patient's new medication at the bedside, study course information, access references during class in response to a question, or download clinical materials from home. Although the benefits of having ready access to information seem obvious, there are costs and strategic planning activities associated with implementing these projects. Clearly, the objective of any academic nursing program is to develop skills among students so they can efficiently access information and use that information to guide their nursing practice. To do so, academic nursing administrators must have the forethought to envision how new technologies can support achieving this goal as well as the ability to put in place the infrastructure supports needed for success. This article presents a case study of how one institution developed the necessary infrastructure and garnished the appropriate resources to implement an ambitious technology initiative integrated throughout a large undergraduate nursing program. In addition, how the integration of technology, online and mobile, can enhance clinical learning will be discussed.

Experiences incorporating Tablet PCcs into clinical pharmacists' workflow.

Tablet PCs are portable computers that combine the power of a laptop with an intuitive pendriven interface that have been heavily promoted for vertical industries such as healthcare. The authors describe their experiences with tablet PCs used by clinical pharmacists in a large academic medical center. A slate tablet with a large screen and wireless networking capability was chosen. Tablet PCs were issued to users with a customized 'pen-friendly" clinical application and secure access to the majority of available electronic patient information. In general, the feedback from the pilot users was positive. Users reported increased efficiency on patient care rounds; they say they reduced or eliminated paper notes and shadow charts from their daily routine. However, researchers also observed that some clinical practice workflow models or clinicians did not benefit from or were hindered by the mobile devices. The department plans to expand the use of tablet PCs through desktop replacement and is developing solutions to increase the applicability of tablet PCs for all clinical models and clinicians.
