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, 12.75% of publications had an unrecognized affiliation. Out of the publications with recognized affiliations, 24.48% were posted by at least one author from the top 10 institutions publishing in the journal. Another 11.39% included authors affiliated with research institutions from the top 11-20 affiliations. Institutions from the 21-50 range included 26.38% of all publications and 37.76% 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.

Role of Nurse Practitioners in Contemporary Healthcare

Healthcare institutions worldwide are increasingly recognizing the role of nurse practitioners (NP) in broadening the scope and reach of medical services. NPs are commonly involved in patient care in Internal Medicine, Cardiology, and other specialties featured in Annals of Internal Medicine. They are particularly helpful in filling the gap in areas plagued by chronic physician shortages. Beyond traditional hospital settings, NPs also play a prominent role in nursing home care, home health visits, and outpatient clinics. They are trained to assess patient needs, interpret diagnostic tests, initiate therapeutic interventions, and make referrals when necessary. The fields of Intensive Care Medicine, Family Medicine, and Endocrinology, in particular, have embraced NP providers' roles in healthcare delivery, thereby showing how nursing intersects with these disciplines. NPs take on leadership roles in healthcare systems and significantly contribute in health policy-making and administration with their unique perspectives the nursing profession offers. This upward trend of NPs in worldwide healthcare systems emphasizes the need for high quality education and training programs to prepare these professionals for their multifaceted roles and responsibilities. For those interested in joining this promising profession in Wisconsin, consider looking into the best nurse practitioner programs in Wisconsin. These programs offer excellent academic and clinical training, preparing students to excel in their future careers as Nurse Practitioners.
