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.

A clinical decision tool for predicting patient care characteristics: patients returning within 72 hours in the emergency department.
The primary purpose of this study was to develop a clinical tool capable of identifying discriminatory characteristics that can predict patients who will return within 72 hours to the Pediatric emergency department (PED). We studied 66,861 patients who were discharged from the EDs during the period from May 1 2009 to December 31 2009. We used a classification model to predict return visits based on factors extracted from patient demographic information, chief complaint, diagnosis, treatment, and hospital real-time ED statistics census. ⋯ The resulting tool could enable ED staff and administrators to use patient specific values for each of a small number of discriminatory factors, and in return receive a prediction as to whether the patient will return to the ED within 72 hours. Our prediction accuracy can be as high as over 85%. This provides an opportunity for improving care and offering additional care or guidance to reduce ED readmission.

The orderly and effective visit: impact of the electronic health record on modes of cognitive control.
The clinical Joint Cognitive System (JCS) includes the clinicians, electronic health record (EHR), and other infrastructure that maintain control in the system in the service of accomplishing clinical goals. The purpose of this study is to examine the relationship between levels of control using the COCOM model (scrambled, opportunistic, tactical, and strategic) and patterns of EHR use. Forty-five primary care visits were observed and audio-recorded. ⋯ Screen changes were recorded and time stamped (as either searching or entering). Levels of control were significantly related to preparation intensity (F (2,23) = 6.62; p=0.01), the number of screen changes involved in both searching (F (2,30) = 6.54; p=0.004), and entering information (F (2,22) = 9.26; p=0.001). Combined with the qualitative data, this pattern of EHR usage indicates that the system as designed may not provide effective cognitive support.
