Abstract:

Background: To examine whether interobserver reliability, decision-making, and confidence in decision-making in thetreatment of distal radius fractures changes if radiographs are viewed on a messenger application on a mobile phonecompared to a standard DICOM viewer.Methods: Radiographs of distal radius fractures were presented to surgeons on either a smart phone using a mobilemessenger application or a laptop using a DICOM viewer application. Twenty observers participated: 10 (50%) wererandomly assigned to the DICOM viewer group and 10 (50%) to the mobile messenger group. Each observer was askedto evaluate the cases and (1) classify the fracture type according to the AO classification, (2) recommend operative orconservative treatment and (3) rate their confidence about this decision.Results: There was no significant difference in interobserver reliability for AO classification and recommendation forsurgery for distal radius fractures in both groups. The percentage of recommendation for surgery was significantlyhigher in the messenger application group compared to the DICOM viewer group (89% versus 78%, P=0.019) and theconfidence for treatment decision was significantly higher in the mobile messenger group compared to the DICOM viewergroup (8.9 versus 7.9, P=0.026).Conclusion: Messenger applications on mobile phones could facilitate remote decision-making for patients with distalradius fractures, but should be used with caution.

Exploring the Potential of a Mobile Messaging Application for Self-Initiated Language Learning

With the rapid expansion of deploying mobile instant messaging applications such as Telegram for the purpose of language learning, it is quite apparent that language research in this regard is lagging behind the trend. This study addressed the matter by exploring how language learners utilize a Telegram group for the purpose of language learning. In this regard, the activities of a Telegram lan...

Interobserver variability in applying a radiographic definition for ARDS.

CONTEXT Acute lung injury (ALI) and ARDS are currently defined by the American-European Consensus Conference (AECC) definition criteria, which contain a radiographic criterion. The accuracy or reliability of this consensus radiographic definition has not been evaluated, and no radiographic definition of ALI-ARDS has been evaluated by a large international group of experts. OBJECTIVE To study ...

assessment of the efficiency of s.p.g.c refineries using network dea

data envelopment analysis (dea) is a powerful tool for measuring relative efficiency of organizational units referred to as decision making units (dmus). in most cases dmus have network structures with internal linking activities. traditional dea models, however, consider dmus as black boxes with no regard to their linking activities and therefore do not provide decision makers with the reasons...

Measurement variance in limb length discrepancy: clinical and radiographic assessment of interobserver and intraobserver variability.

The purpose of this study was to assess interobserver and intraobserver variability in the assessment of clinical and radiographic measurement of lower limb length discrepancy. Clinical measurements included direct measurement with a tape measure from anterior superior iliac spine (ASIS) to lateral malleolus and ASIS to medial malleolus as well as block measurement. Slit scanogram radiographic ...
