Citation analysis of publications

A Citation Analysis of the Top 50 Most Cited Nurse Practitioner Publications

The role of nurse practitioners (NPs) has become integral to healthcare systems worldwide. Originating in the United States over 50 years ago, it has since been adopted by countries such as Canada, the United Kingdom, and Australia. To honor the research and contributions that have shaped the NP discipline, it is valuable to review and recognize key literature that has significantly impacted its development. Bibliometrics, a research methodology, offers an objective lens for evaluating the influence of scholarly articles on the evolution of a discipline. Citation analysis (CA), a key method in bibliometrics, examines how frequently a publication is cited by others, often serving as a measure of its impact, influence, and contribution to its field. This study aims to identify the top 50 most cited publications related to NPs in the Web of Science (WoS) database to review and describe the influential works that have contributed to the profession's growth. Comparisons are drawn with a parallel review in Scopus and recent NP-related bibliometric studies. In 2021, a structured search was conducted using the WoS Core Collection with key terms such as "Nurse Practitioner" and "Advanced Practice Nurse". Inclusion and exclusion criteria were applied, and publications were ranked by citation count from highest to lowest. The analysis covered citation counts, topics, publication dates/types, country of origin, author details (institution and discipline), and journal characteristics (e.g., impact factor, IF). The top 50 most cited articles and their characteristics are presented. Citation counts ranged from 78 to 656, with publication dates spanning six decades across 30 journals, 38 institutions, and 194 authors. The leading authors were Mary O'Neil Mundinger, Denise Bryant-Lukosius, and Alba DiCenso. Topics included the role's impact and development, registration/licensing, and scope of practice. Most articles (n = 35) were published in journals with an IF greater than 2. This review offers a systematic approach to identifying seminal works that have influenced the NP profession globally. While CA has its limitations, it provides a valuable method for literature review. This study contributes valuable insights into the history and development of NP research and offers guidance for future research efforts.

Global research hotspots and trends on robotic surgery in obstetrics and gynecology: a bibliometric analysis based on VOSviewer

Objective

Over the last two decades, the quantity of papers published in relation to robotic surgery in obstetrics and gynecology has continued to grow globally. However, no bibliometric analysis based on VOSviewer has been performed to evaluate the past and present of global research in the field. In this study, we aimed to analyze the bibliometric characteristics of papers on robotic surgery in obstetrics and gynecology to reveal research hotspots and trends in this field.

Methods

The Web of Science Core Collection was searched for scientific papers on robotic surgery in obstetrics and gynecology published between January 1, 1998 and December 31, 2023. Bibliometric metadata of each selected paper was extracted for analysis. The results were visualized by VOSviewer (version 1.6.18).

Results

A total of 1,430 papers met the inclusion criteria. The United States had the highest total link strengths and contributed the most papers (n = 793). The Mayo Clinic produced the largest number of papers (n = 85), and Professor Pedro T Ramirez contributed the most papers (n = 36). The number of citations ranged from 0 to 295 with a total sum of 29,103. The Journal of Minimally Invasive Gynecology published the most relevant papers (n = 252). Keywords were classified into six clusters based on co-occurrence data, of which cluster 1, cluster 4 and cluster 6 had more main keywords with the largest average publication year.

Conclusions

This is the first VOSviewer-based bibliometric analysis of robotic surgery research in obstetrics and gynecology. The United States was the leading country, and the Journal of Minimally Invasive Gynecology was the most productive journal in the field. Scientists and institutions from around the world should push their boundaries to bring about deep collaboration. The main research topic has always been the use of robotic surgery in the treatment of gynecologic malignancies. More randomized controlled trials need to be conducted to compare surgical outcomes of robotic surgery with other surgical approaches. Robotic sacrocolpopexy for pelvic organ prolapse has become a new research hotspot, and robotic surgery for sentinel lymph node detection in gynecologic malignancies are more potential directions for future research.

Results of 25 years of Maghrebian scientific medical research in the Grand Maghreb. Bibliometric analysis of the Scimago platform (1996-2020)

OBJECTIVE

Describe the trend and the characteristics of the positioning of Maghreb medical production and its visibility, at the global, African and Arab level, following an in-depth reading of the Scimago platform, over a period of 25 years (1996-2020 ).

METHODS

This is an in-depth reading, centered on the Maghreb, of the Maghreb medical production referenced on the Scimago platform, from 1996 to 2020. The bibliometric extracts were based on the number of published "documents" and the index H: number of articles (h) from a country having received at least h citations. The benchmarking of the productivity and medical visibility of the five Maghreb countries (Tunisia, Morocco, Algeria, Libya, Mauritania) was carried out at the global (237 countries), African (59 countries) and Arab (21 countries) level.

RESULTS

Following the first African countries producing the most medical documents (South Africa, Egypt and Nigeria), the position of the Maghreb countries varied from 4 in Tunisia to 36 in Mauritania. In Arab countries, the position of medical production, dominated by Egypt and Saudi Arabia, was 12 and 18, successively in Algeria and Libya. The evolution of medical documents recorded a cross between Tunisia and Morocco in 2014, followed by a deceleration in Moroccan production. In the Maghreb, the h index varied from 154 in Tunisia to 29 in Mauritania.

CONCLUSION

In addition to its weak position in the world, African and Arab rankings over the past 25 years, Maghreb medical research has been characterized by a major fluctuation. The "Alliance for Excellence" charter of the PRP2S Network, based on the promotion of university essays and electronic journals, constitutes an operational roadmap for the development of the production and visibility of research in the Maghreb.
