Publication chance based on affiliation

The publication chance index shows the ratio of articles published by the best research institutions in the journal edition to all articles published within that journal. The best research institutions were selected based on the largest number of articles published during all editions of the journal.

The chart below presents the percentage ratio of articles from top institutions (based on their ranking of total papers).Top affiliations were grouped by their rank into the following tiers: top 1-10, top 11-20, top 21-50, and top 51+. Only articles with a recognized affiliation are considered.

During the most recent 2021 edition, 73.55% of publications had an unrecognized affiliation. Out of the publications with recognized affiliations, 23.43% were posted by at least one author from the top 10 institutions publishing in the journal. Another 12.19% included authors affiliated with research institutions from the top 11-20 affiliations. Institutions from the 21-50 range included 16.09% of all publications and 48.28% were from other institutions.

Returning Authors Index

A very common phenomenon observed among researchers publishing scientific articles is the intentional selection of journals they have already attended in the past. In particular, it is worth analyzing the case when the authors participate in the same journal from year to year.

The Returning Authors Index presented below illustrates the ratio of authors who participated in both a given as well as the previous edition of the journal in relation to all participants in a given year.

Returning Institution Index

The graph below shows the Returning Institution Index, illustrating the ratio of institutions that participated in both a given and the previous edition of the conference in relation to all affiliations present in a given year.

The experience to innovation index

Our experience to innovation index was created to show a cross-section of the experience level of authors publishing in a journal. The index includes the authors publishing at the last edition of a journal, grouped by total number of publications throughout their academic career (P) and the total number of citations of these publications ever received (C).

The group intervals were selected empirically to best show the diversity of the authors' experiences, their labels were selected as a convenience, not as judgment. The authors were divided into the following groups:

  • Novice - P < 5 or C < 25 (the number of publications less than 5 or the number of citations less than 25),
  • Competent - P < 10 or C < 100 (the number of publications less than 10 or the number of citations less than 100),
  • Experienced - P < 25 or C < 625 (the number of publications less than 25 or the number of citations less than 625),
  • Master - P < 50 or C < 2500 (the number of publications less than 50 or the number of citations less than 2500),
  • Star - P ≥ 50 and C ≥ 2500 (both the number of publications greater than 50 and the number of citations greater than 2500).

The chart below illustrates experience levels of first authors in cases of publications with multiple authors.

Exploring Fields Outside Gastroenterology

One of the unique aspects in the field of medical research is the intersectionality that occurs between different disciplines. In various instances, the correlation between Gastroenterology and other specialization areas, such as nursing, help to complement and enhance understandings. This allows for the breakdown of complex medical phenomena into tangible and practicable insights that can be applied in various scenarios, ultimately improving patient care. One of the areas where such an overlap has been observed is in nursing. This is particularly seen in aspects of care related to gastrointestinal diseases, where the nurse's role in patient management, symptom identification, disease prevention, and even post-treatment care are crucial. This connection not only broadens the scope of knowledge but also promotes an integrative approach towards healthcare service delivery. Specifically, in the context of nursing education, the need for resources aligned with these areas of intersectionality is essential to ensure a comprehensive understanding of unique patient care needs in different scenarios. One resource that stands out is the online programs, which align nursing education with a particular focus on areas such as Gastroenterology. A stellar example of this would be the best online nursing programs in Nebraska, where students can study and understand these intersections in-depth as part of their curriculum. Through integrating various approaches in patient care, nursing professionals from such programs provide holistic care to patients and become more effective facilitators of health and wellness. Moreover, this multilayered approach towards education ensures that graduates are not just well versed in their primary field of study, but are also able to understand the wider connections it has with other medical disciplines. This depth and breadth of study make these programs truly stand out. Thus, the intersection between Gastroenterology and nursing is an essential area for ongoing research and exploration for both educational and healthcare institutions. These interconnections and overlapping areas of study can become key strategies towards improving healthcare services and establishing an integrated approach towards patient care. By acknowledging and promoting these aspects, the field of Gastroenterology and other medical disciplines will continue to evolve, providing better outcomes for patients and the medical community.
