NOTE: This is an unreviewed Preprint
Warning: This is a unreviewed preprint (What is a preprint?). Readers are warned that the document has not been peer-reviewed by expert/patient reviewers or an academic editor, may contain misleading claims, and is likely to undergo changes before final publication, if accepted, or may have been rejected/withdrawn (a note "no longer under consideration" will appear above).
Peer review me: Readers with interest and expertise are encouraged to sign up as peer-reviewer, if the paper is within an open peer-review period (in this case, a "Peer Review Me" button to sign up as reviewer is displayed above). All preprints currently open for review are listed here. Outside of the formal open peer-review period we encourage you to tweet about the preprint.
Citation: Please cite this preprint only for review purposes or for grant applications and CVs (if you are the author).
Final version: If our system detects a final peer-reviewed "version of record" (VoR) published in any journal, a link to that VoR will appear below. Readers are then encourage to cite the VoR instead of this preprint.
Settings: If you are the author, you can login and change the preprint display settings, but the preprint URL/DOI is supposed to be stable and citable, so it should not be removed once posted.
Submit: To post your own preprint, simply submit to any JMIR journal, and choose the appropriate settings to expose your submitted version as preprint.
Warning: This is an author submission that is not peer-reviewed or edited. Preprints - unless they show as "accepted" - should not be relied on to guide clinical practice or health-related behavior and should not be reported in news media as established information.
Hot Topics and Fronts in E-health Research: A Scientometric Analysis in CiteSpace
Background:
E-health is the use of information and communication technology to treat patients. It has many benefits like cost reduction (e.g., health delivery cost), convenience for users, and health policy system improvement. Several literature reviews have included one part or the other of the field, but an overall review is lacking possibly due to the field’s constant evolution. An overview of E-health research is needed.
Objective:
To show an over view of E-health research and lay a foundation for futhers research on health IT policy.
Methods:
We selected the related literature on E-health downloaded from Web of Science as data source and used the visualization analysis function of CiteSpace. Literature information would be converted into precise mapping knowledge domain. Through further analysis of mappings, we explored the theoretical framework and the forefront in the field of E-health.
Results:
Over the past 15 years, USA, England, and Australia were the top three countries that published the largest number of papers. Researches about Internet technology, telemedicine,m-health, and healthcare lay the basis of E-health research development. Particularly, m-health, health system management, and experimental intervention have emerged and formed the new study frontier in recent 3-5 years. With the advancement of E-health projects, an increasing number of scholars have been studying the commercialization of E-health.
Conclusions:
We analyzed the international studies from the aspects of the references’ quantity, country, author, keywords, and co-cited references. This paper provides a reference for scholars working on this field and lays a foundation for further research on health IT policy.
