Moving mobile: using an open-sourced framework to enable a web-based health application on touch devices.
Computer devices using touch-enabled technology are becoming more prevalent today. The application of a touch screen high definition surgical monitor could allow not only high definition video from an endoscopic camera to be displayed, but also the display and interaction with relevant patient and health related data. ⋯ This paper describes an approach taken to overcome these problems. A real case study was used to demonstrate the novelty and efficiency of the proposed method.

Observational StudyEfficiency strategies for facilitating computerized clinical documentation in ambulatory care.
Most providers have experienced increased documentation demands with the use of electronic health records (EHRs). We sought to identify efficiency strategies that providers use to complete clinical documentation tasks in ambulatory care. Two observers performed ethnographic observations and interviews with 22 ambulatory care providers in a U. ⋯ Findings included: the use of paper artifacts for handwritten notations; electronic templates for automation of certain parts of the note; use of shorthand and phrases rather than narrative writing; copying and pasting from previous EHR notes; directly entering information into the EHR note during the patient encounter; reliance on memory; and pre-populating an EHR note prior to seeing the patient. We discuss the findings in the context of distributed cognition to understand how clinical information is propagated and represented toward completion of a progress note. The study findings have important implications for improving and streamlining clinical documentation related to human factors workload management strategies.

Overrides of clinical decision support alerts in primary care clinics.
Clinical Decision Support (CDS) systems can alert physicians about potential clinical risks and suggest suitable treatment alternatives at appropriate times in the health care process. We evaluated the frequency with which physicians overrode medication alerts and the override reasons provided. ⋯ Physicians overrode more than half of CDS medication alerts, with formulary, age-based, and renal substitutions the most likely. Many drug-drug and drug-allergy interactions overridden had the potential to cause patient harm.

Development of an early detection and monitoring system for deteriorating patients.
A number of methods of preventing cardiopulmonary arrest are currently in use. One such method is the alert response system developed by Seoul National University Children's Hospital, which is an early detection and monitoring system for deteriorating patients who are at risk of cardiopulmonary arrest. This system offers an effective means of detecting early warning signs and monitoring deteriorating patients, and its application can reduce rates of cardiopulmonary arrest.

Do electronic health records help undergraduate health informatics students to develop health informatics competencies?
The purpose of this paper is to determine the effects of hands-on exposure to an educational electronic health record (EHR) system upon undergraduate health informatics (HI) student competency development. We undertook a quasi-experimental study (i.e. pre-test, post-test design), where students were given the opportunity to do hands-on work with an educational EHR over a 10 week period. ⋯ Several HI student competencies improved significantly following hands-on work with the EHR. As well, students provided more higher quality case study answerfollowing EHR use.
