Overview

Top Research Topics at Sleep Medicine?

The objective of Sleep Medicine is to combine knowledge in the areas of Sleep in non-human animals, Internal medicine, Obstructive sleep apnea, Polysomnography and Physical therapy. The journal holds forums on Sleep in non-human animals that merges themes from other disciplines such as Clinical psychology and Audiology. While Internal medicine is the focus of Sleep Medicine, it also provided insights into the studies of Endocrinology and Cardiology.

In the journal, Sleep apnea, Epworth Sleepiness Scale, Pediatrics and Hypopnea are investigated in conjunction with one another to address concerns in Obstructive sleep apnea research. It focuses on Pediatrics research which is adjacent to topics in Narcolepsy. Sleep Medicine investigates Polysomnography research which frequently intersects with Anesthesia.

Sleep Medicine focuses on Physical therapy as well as the interrelated topic of Restless legs syndrome. Insomnia and Depression (differential diagnoses) are Psychiatry topics of special interest in Sleep Medicine.

  • Sleep in non-human animals (24.26%)
  • Internal medicine (22.94%)
  • Obstructive sleep apnea (17.20%)

What are the most cited papers published in the journal?

  • Validation of the Insomnia Severity Index as an outcome measure for insomnia research (3564 citations)
  • Restless legs syndrome: diagnostic criteria, special considerations, and epidemiology. A report from the restless legs syndrome diagnosis and epidemiology workshop at the National Institutes of Health. (2483 citations)
  • Validation of the International Restless Legs Syndrome Study Group rating scale for restless legs syndrome (1200 citations)

Research areas of the most cited articles at Sleep Medicine:

The most cited articles primarily tackle Polysomnography, Physical therapy, Sleep in non-human animals, Psychiatry and Internal medicine. Issues in Polysomnography were discussed in the most cited articles, taking into consideration concepts from other disciplines like Sleep apnea, Anesthesia, Obstructive sleep apnea, Audiology and Non-rapid eye movement sleep. The most cited papers explore topics in Sleep in non-human animals which can be helpful for research in disciplines like Developmental psychology and Gerontology.

What topics the last edition of the journal is best known for?

  • Internal medicine
  • Disease
  • Surgery

The previous edition focused in particular on these issues:

Sleep Medicine mostly deals with topics like Sleep in non-human animals, Internal medicine, Obstructive sleep apnea, Insomnia and Polysomnography. The majority of Sleep in non-human animals studies presented zero in on Sleep disorder. The featured Internal medicine works encompass concepts such as Sleep apnea, Continuous positive airway pressure and Meta-analysis and examines them in conjunction with In patient.

The research on Insomnia tackled can also make contributions to studies in the areas of Depression (differential diagnoses), Pittsburgh Sleep Quality Index and Clinical psychology. The featured Clinical psychology studies mainly concentrate on Anxiety but also cover areas of interest in Mental health. The work on Polysomnography addressed in it expands to the thematically related Non-rapid eye movement sleep.

The most cited articles from the last journal are:

  • The immediate impact of the 2019 novel coronavirus (COVID-19) outbreak on subjective sleep status. (79 citations)
  • The acute effects of the COVID-19 pandemic on insomnia and psychological symptoms. (47 citations)
  • Perceived stress and sleep quality among the non-diseased general public in China during the 2019 coronavirus disease: a moderated mediation model. (44 citations)

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, 5.56% of publications had an unrecognized affiliation. Out of the publications with recognized affiliations, 14.00% were posted by at least one author from the top 10 institutions publishing in the journal. Another 8.92% included authors affiliated with research institutions from the top 11-20 affiliations. Institutions from the 21-50 range included 16.23% of all publications and 60.85% 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.

Career Opportunities and Licenses Required in Sleep Medicine

An interesting topic that hasn't been addressed in this article is the career opportunities associated with Sleep Medicine. It is encouraging to see so many multifaceted areas of study in this field—from Pediatrics to Physical Therapy, Audiology, and Psychiatry. But what are the professional opportunities for those who study Sleep Medicine? And what licenses or certifications are necessary for these roles?

For example, a background in Sleep Medicine could lead to a career as a Sleep Medicine Specialist, where you'll diagnose and treat sleep disorders such as insomnia, sleep apnea, and restless leg syndrome. Alternatively, you could leverage your understanding of sleep and its impact on health to work as a Health and Wellness Consultant or Life Coach, guiding people to establish sleep routines that support their individual needs.

Another professional avenue you could explore is becoming a speech-language pathologist, a role which often interfaces with sleep medicine when treating conditions like obstructive sleep apnea. In fact, speech-language pathologists can play a crucial role in diagnosing and managing sleep disorders that are related to or impact speech and swallowing functions.

As per licensing, the requirements often depend on your location and professional role. In some states, including Kansas, specific licensing requirements exist for professions such as speech-language pathologists. You can get more information about the requirements for this profession particularly in Kansas on kansas slp license requirements.

While this is a broad overview of potential career paths, it is important to research and understand the role you're considering, its requirements, and how studying Sleep Medicine fits into your professional goals.
