Emergency department physician internet use during clinical encounters.
This study explored the Internet log files from emergency department workstations to determine search patterns, compared them to discharge diagnoses, and the emergency medicine curriculum as a way to quantify physician search behaviors. ⋯ We have shown a need for a readily accessible drug knowledge base within the EMR for decision support as well as easier access to first and second tier EBM evidence.

A usability problem: conveying health risks to consumers on the Internet.
Effectively designing risk information for the public is challenging and selecting the appropriate medium to deliver disease risk information is crucial. In a usability evaluation of a colon cancer risk website, we evaluated the public's understanding and interpretation of graphical displays of risk information (2 bar graphs). Results from this study suggest that many people do not understand risk and often misinterpret graphical displays of risk and associated terminology. This work shows the importance of not only including representational analysis within user-centered design of consumer health websites, but also evaluating the health and numerical literacy levels of these websites as an aspect of usability testing.

We present and test the intuition that letters to the editor in journals carry early signals of adverse drug events (ADEs). Surprisingly these letters have not yet been exploited for automatic ADE detection unlike for example, clinical records and PubMed. Part of the challenge is that it is not easy to access the full-text of letters (for the most part these do not appear in PubMed). ⋯ We also involve natural language processing for feature definitions. Overall we achieve high accuracy in our experiments and our method also works well on a second new test set. Our results encourage us to further pursue this line of research.

Comparative StudyEnsuring patient safety in care transitions: an empirical evaluation of a Handoff Intervention Tool.
Successful handoffs ensure smooth, efficient and safe patient care transitions. Tools and systems designed for standardization of clinician handoffs often focuses on ensuring the communication activity during transitions, with limited support for preparatory activities such as information seeking and organization. ⋯ We found that the use of HAND-IT led to fewer transition breakdowns, greater tool resilience, and likely led to better learning outcomes for less-experienced clinicians when compared to the current tool. We discuss the implications of our results for improving patient safety with a continuity of care-based approach.

Finding hidden sources of new work from BCMA implementation: the value of an organizational routines perspective.
It is acknowledged that there is a difference between abstract representations of clinical work and work as it is performed in context. In this qualitative study of the implementation of barcode medication administration (BCMA), hidden work resulting from the implementation of BCMA is described. ⋯ Because many of these tasks were not part of the commonly understood workflow of the BCMA system and because they were obscured in problematic interactions between organizational routines, they are characterized as "hidden work". Categories of hidden work are described and the implications for implementation research and practice are discussed.
