A bibliometric analysis and typology of drug pricing policies across the globe.

Limited research exists on pricing policies from a bibliometric and visualization perspective, and there is a lack of understanding of their typology. This study aims to address these gaps in knowledge and provide a deeper understanding of the research topics and development trends in this field. A bibliometric study was conducted on drug pricing approaches in healthcare literature, published between 2000 and June 2023. The literature was identified through an extensive search of healthcare databases and was then classified based on the year of publication, research topics, corresponding authors, location of corresponding authors, and journal titles. The citation data analysis was conducted using Bibliometrix, which consisted of descriptive, geographical, and time-series analyses and visualization. Between 2000 and June 2023, 173 articles were disseminated across 98 distinct publication sources. During the analysis, we observed a significant and consistent rise in literature reports on drug pricing approaches in healthcare, especially in 2010. The research topics were distributed almost equally, discussing improvement or issues with drug pricing models and addressing drug pricing applications. Our analysis revealed that the top ten corresponding authors were responsible for 19% of the total articles, with those based in the United States being the most productive. Furthermore, the "Health Economics" journal ranked first among the top ten journals. These findings align with the overall publication trends of drug pricing methods reported in other fields. The current study offers a comprehensive overview of drug pricing techniques utilized in medicine through visualization and bibliometric techniques. Analysis of authors, journals, institutions, and countries could serve as a reference for new researchers and guide them differently. Researchers can also consider emerging trends when determining the focus of their studies.

Examining Rate and Pattern of Author Self-Citation in Nepalese Journals

This bibliometric study has explored the frequency of the author self-citation, investigated the structure of author self-citation, and explored the association in terms of the number of authors, number of references, and author self-citation in the article from 18 journals published by different departments/campuses of eight faculties/institutes of Tribhuvan University. All the selected journals are indexed in the Nepal Journals Online (NepJOL) database, the only indexing of Nepal. The study incorporated the most recent five journal issues, proportionally selected based on the representation of disciplines indexed in the database, from three faculties and five institutes of Tribhuvan University. The Faculty of Law was excluded due to the unavailability of journals. However, The Forestry: Journal of the Institute of Forestry, Nepal, was included despite having only four issues, to ensure representation of the discipline rather than excluding it entirely. Through the process, the study included 1,115 articles from 18 journals for descriptive and inferential analyses. Necessary information was manually collected from the articles to analyze the interconnectivity among the number of author self-citations, author(s), and references in the references section. As a result, author self-citation in journals varies from 11% in engineering to 70% in science and technology. The overall author self-citation rate is 29.6% in these 1,115 articles. Moreover, it is inferred that author self-citation is positively correlated with the number of authors per article and the number of references listed, and the self-citation behavior differs significantly across journals and faculties. In instances, where journals exhibit a high rate of author self-citation, it is recommended that editors and reviewers conduct a thorough review of the submitted manuscripts. Additionally, the study calls for a qualitative investigation to explore the underlying dynamics of the author self-citation. This investigation should determine whether the observed self-citations are an inherent aspect of scholarly practice or if they are strategically inserted for citation purposes in specific contexts.
