Towards Assisted Moderation in Online Healthcare Social Networks: Improving Trust in YouTube Searches.
Moderation of content in online Health Social Networks (HSN) is critical because information is not only published and produced by experts or health professionals, but also by users of that information. The objective of this paper is to propose a semi-automatic moderation Web Service for assessing the quality (trustworthiness) of health-related videos published on the YouTube social network. ⋯ The service is a RESTful service which can be integrated into open source Virtual Social Network Platforms, therefore improving trust in the process of searching and publishing content extracted from YouTube. A preliminary pilot evaluation in a simple use case demonstrated that the relevance of videos retrieved using the moderation service was higher compared to the relevance of the videos retrieved using the YouTube search engine.

Multicenter StudyExamination of changes in pathology tests ordered by Diagnosis-Related Group (DRGs) following CPOE introduction.
Electronic test ordering, via the Electronic Medical Record (EMR), which incorporates computerised provider order entry (CPOE), is widely considered as a useful tool to support appropriate pathology test ordering. Diagnosis-related groups (DRGs) are clinically meaningful categories that allow comparisons in pathology utilisation by patient groups by controlling for many potentially confounding variables. This study used DRG data linked to pathology test data to examine changes in rates of test ordering across four years coinciding with the introduction of an EMR in six hospitals in New South Wales, Australia. ⋯ We investigated patients with a Chest pain DRG to examine whether tests rates changed for specific test groups by hospital emergency department (ED) pre- and post-EMR. There was little change in testing rates between EDs or between time periods pre- and post-EMR. This is a valuable method for monitoring the impact of EMR and clinical decision support on test order rates.

Controlled Clinical TrialEndotracheal intubation with a traditional videolaryngoscope blade versus an integrated suction blade in a hemorrhagic airway cadaver model.
Lightly embalmed hemorrhagic cadaver models and the Storz CMAC videolaryngoscope fitted with either an integrated suction blade vs. a traditional blade were used to determine efficacy of the instruments in hemorrhagic airway intubation. Significant differences were found between the devices in intubation success rates of the viscosity saliva and frothy blood models, as well as a significant difference in intubation times in the frothy blood model. Feedback provided by the study participants indicated preference for the integrated video suction blade in hemorrhagic airway intubation.
