A domain-based approach for retrieving trustworthy health videos from YouTube.
Health information retrieval and YouTube can be used as powerful tools to improve user's health knowledge. However, YouTube videos must be carefully analysed in order to avoid misleading, inaccurate, obsolete and incorrect health content. ⋯ Video and channel metadata are used to automatically determine if a video is provided by a trusted source. The approach is tested and results show that the amount of relevant and reliable videos ranked within top-10 increase when using Domain-based ranking, compared with the original YouTube ranking.

Automatic system testing of a decision support system for insulin dosing using Google Android.
Hyperglycaemia in hospitalized patients is a common and costly health care problem. The GlucoTab system is a mobile workflow and decision support system, aiming to facilitate efficient and safe glycemic control of non-critically ill patients. Being a medical device, the GlucoTab requires extensive and reproducible testing. ⋯ In 144 data points (12.1%), calculation errors of physicians and nurses in the PBCT were detected. The test framework was able to verify manual calculation of insulin doses and detect relatively many user errors and workflow anomalies in the PBCT data. This shows the high potential of the electronic decision support application to improve safety of implementation of an insulin titration protocol and workflow management system in clinical wards.

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.

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.

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.
