A bibliometric analysis of medical informatics and telemedicine in sub-Saharan Africa and BRICS nations

The advances in eHealth have dramatically changed the face of healthcare delivery around the world, with Sub-Saharan Africa being no exception. It is essential to identify the prominent, emerging researchers, successful areas of research within the field of health informatics (HI) and telemedicine (TM) to be duplicated where there is a need. This study gives a bibliometric overview of original research articles on medical informatics and telemedicine indexed in Scopus, PubMed, and Science Direct over the last 20 years in sub-Saharan Africa. Keywords related to health informatics and telemedicine were used to retrieve relevant literature. We specifically analyzed the evolution, standard metrics, domains of medical informatics (MI) and TM in sub-Saharan Africa (SSA) and Brazil, Russia, India, China, and South Africa (BRIC) nations. Our results identified mhealth as the main field of research in telemedicine that has seen significant growth in both BRIC and SSA nations and is poised to be the focus of research activity in the near future. Research production in mhealth and telemedicine showed a considerable increase from 1999-2018. The production was dominated by articles from South Africa in Africa and China from the BRIC nations. Most prolific authors have resources and are leaders of health informatics projects. The production came from 26 sub-Saharan African countries, denoting this field's devotion in different areas around sub-Sahara. Research in mhealth needs to be encouraged, mostly in the fight against infectious and non-infectious diseases in sub-Saharan Africa, where technology can improve health services and decrease disease burden.

Harnessing Telemedicine for the Provision of Health Care: Bibliometric and Scientometric Analysis

Background

In recent decades, advances in information technology have given new momentum to telemedicine research. These advances in telemedicine range from individual to population levels, allowing the exchange of patient information for diagnosis and management of health problems, primary care prevention, and education of physicians via distance learning.

Objective

This scientometric investigation aims to examine collaborative research networks, dominant research themes and disciplines, and seminal research studies that have contributed most to the field of telemedicine. This information is vital for scientists, institutions, and policy stakeholders to evaluate research areas where more infrastructural or scholarly contributions are required.

Methods

For analyses, we used CiteSpace (version 4.0 R5; Drexel University), which is a Java-based software that allows scientometric analysis, especially visualization of collaborative networks and research themes in a specific field.

Results

We found that scholarly activity has experienced a significant increase in the last decade. Most important works were conducted by institutions located in high-income countries. A discipline-specific shift from radiology to telestroke, teledermatology, telepsychiatry, and primary care was observed. The most important innovations that yielded a collaborative influence were reported in the following medical disciplines, in descending order: public environmental and occupational health, psychiatry, pediatrics, health policy and services, nursing, rehabilitation, radiology, pharmacology, surgery, respiratory medicine, neurosciences, obstetrics, and geriatrics.

Conclusions

Despite a continuous rise in scholarly activity in telemedicine, we noticed several gaps in the literature. For instance, all the primary and secondary research central to telemedicine was conducted in the context of high-income countries, including the evidence synthesis approaches that pertained to implementation aspects of telemedicine. Furthermore, the research landscape and implementation of telemedicine infrastructure are expected to see exponential progress during and after the COVID-19 era.

Trends in the growth of literature of telemedicine: A bibliometric analysis

Over the past two decades, the use of telemedicine as a way to provide medical services has grown as communication technologies advance and patients seek more convenient ways to receive care. Because developments within this field are still rapidly evolving, identifying trends within telemedicine literature is an important task to help delineate future directions of telemedicine research. In this study, we analyzed 7960 telemedicine-related publication records found in the Science Citations Index - Expanded database between 1993 and 2012. Bibliometric analyses revealed that while the total growth in telemedicine literature has been significant in the last twenty years, the publication activity per country and over time has been variable. While the United States led the world in the cumulative number of telemedicine publications, Norway ranked highest when we ordered countries by publications per capita. We also saw that the growth in the number of publications per year has been inconsistent over the past two decades. Our results identified that neuroscience neurology and nursing as two fields of research in telemedicine that have seen considerable growth in interest in this field, and are poised to be the focus of research activity in the near future.

Telemedicine and E-Learning in a Primary Care Setting in Sudan: The Experience of the Gezira Family Medicine Project

Information and communication technology (ICT) is progressively used in the health sector (e-health), to provide health care in a distance (telemedicine), facilitate medical education (e-learning), and manage patients' information (electronic medical records, EMRs). Gezira Family Medicine Project (GFMP) in Sudan provides a 2-year master's degree in family medicine, with ICT fully integrated in the project. This cross-sectional study describes ICT implementation and utilization at the GFMP for the years 2011-2012. Administrative data was used to describe ICT implementation, while questionnaire-based data was used to assess candidates' perceptions and satisfaction. In the period from April 2011 to December 2012, 3808 telemedicine online consultations were recorded and over 165000 new patients' EMRs were established by the study subjects (125 candidates enrolled in the program). Almost all respondents confirmed the importance of telemedicine. The majority appreciated also the importance of using EMRs. Online lectures were highly rated by candidates in spite of the few challenges encountered by combining service provision with learning activity. Physicians highlighted some patients' concerns about the use of telemedicine and EMRs during clinical consultations. Results from this study confirmed the suitability of ICT use in postgraduate training in family medicine and in service provision.
