Telemedicine: Niche or mainstream? A bibliometric analysis and review of the output of highly ranked clinical journals.

Historically, telemedicine research is predominantly published in discipline-specific telemedicine journals. However, in recent times the number of publications on telemedicine in clinical journals has increased. Acceptance of telemedicine research by clinical journals indicates a maturing of the telemedicine field. This bibliometric study reviewed telemedicine-related literature published in clinical journals from 2008 to 2018. A search was conducted in PubMed using two types of clinical outlets. (1) Top 20 journals with highest Impact Factor in the field of Medicine. (2) Top five journals with highest Impact Factor in most common Medical Specialty Areas. Analysis showed that there is a steady growth of literature relating to research and non-research publications appearing in clinical journals. Top five journals in the field of Medicine - BMJ, JAMA, Cochrane database, Medical Journal of Australia and Lancet have published 64% (n = 270) of telemedicine-related articles for the study period. Disease areas associated with telemedicine publications are consistent with global disease priorities. The review demonstrated that the most significant increase in telemedicine research published in clinical journals was focused on patient care.
