Focus and Scope

The Journal of Comorbidity is an international, open-access, peer-reviewed journal that publishes original clinical and experimental research articles on the pathophysiology, prevention, diagnosis and management of comorbidity/multimorbidity.


The Journal of Comorbidity serves as a platform for an exchange of ideas and working principles/practices of clinical management within a multitherapeutic framework. The journal brings together diverse aspects of medicine in order to optimize the management of patients with comorbidity/multimorbidity.

Our vision is to be a leading global information resource to improve the health and wellbeing of patients with comorbidity/multimorbidity. 

In addition to original papers, the journal publishes guidelines, policies, editorials, commentaries, protocols, and critical review articles, as well as proceedings of congresses. Preference is given to articles that advance the clinical management of patients. The Editorial Board also welcomes ideas and suggestions for special issues dedicated to unique themes.

We welcome presubmission enquiries: if you are in doubt about the suitability of your article, please contact our editorial team at editorial@jcomorbidity.com or submissions@jcomorbidity.com

Peer Review Process

To ensure a high standard of quality science, all articles submitted to JOC are editorially independent and subject to rigorous peer review by a minimum of two external referees who possess expertise in the subject covered by the manuscript.

JOC operates an open peer-review process in that the authors' and reviewers' identities are known to each other. The identities of the reviewers are not published, nor are the reviewer evaluations or author responses.

When submitting an article, authors are invited to suggest two to four external reviewers who are regarded as experts in the field of study and the subject matter of the article. Although helpful, these suggestions may not always be followed. Authors should not suggest anyone who has published with any of the co-authors within the last 5 years, anyone who works at the co-authors’ institutions, or anyone who has any kind of potential conflict of interest (e.g. personal, financial). You may request that some referees not be involved in the review of your article. Minimum referee information should include first and last names, affiliation and e-mail address. 


All articles submitted to JOC are first reviewed by the Editorial Team to determine its merit for peer review: it must be of sufficient scientific quality and fall within the scope of the journal. Articles that meet the journal standards are sent for peer review.


Peer reviewers make one of four possible recommendations:

  1. Accept unaltered
  2. Accept after minor revision*
  3. Review again after major revision*
  4. Reject: if manuscript is flawed or not sufficiently novel.


In cases where peer reviewers make no decision or have conflicting decisions, the article will either be sent to an additional reviewer or a Co-Editor-in-Chief will make the final decision.


*For accepted articles requiring changes, authors are given a maximum of 2 months for revision. After 2 months, revised manuscripts will be considered new submissions.


Following acceptance, authors may be requested to have their articles edited to improve the language and/or to conform to journal style. Additionally, prior to publication, all articles will undergo plagiarism detection using iThenticate software to ensure content originality and the highest quality written work.


Publication Frequency

All articles to JOC are posted online as soon as they are ready for publication.


Open Access Policy

JOC is published under the Creative Commons Attribution-NonCommercial 4.0 License (CC BY-NC 4.0). Articles are therefore free for everyone to read, download, copy, distribute, print, search, or link to the full texts, provided the original work is appropriately credited, and include a link to the license, and indicate if any changes were made. In cases of reuse, copy or distribution for commercial purposes, permission from the publisher is required.

Articles will be published immediately after the final corrections of the master proof have been made. 


Publication fee

The publication of an article in JOC incurs a processing fee of EUR 950 per article (excl. VAT) of up to seven typeset pages (A4). For each additional typeset page a charge of EUR 50 is incurred. It is customary that the author's institution covers the publication costs for articles resulting from research undertaken at the institution, or that money has been earmarked in the grant or stipend that the author has received to be able to carry out the research.

Publication fees may be waived for authors from developing countries lacking sufficient research funding, according to the World Bank classification of low- and middle-income countries as of January 2016. Individual waiver requests will be considered on a case-by-case basis and may be granted in circumstances of lack of funds. The ability of authors to pay remains unknown to the Editors prior to possible acceptance. Commentaries and editorials do not incur an article publication fee.


Access and Permissions


JOC provides immediate, permanent open access to its content on the principle that making research freely available to the public supports a greater global exchange of knowledge.


Permission to copy, distribute, transmit and adapt material published in JOC is granted, provided the original work is appropriately credited (author names and full publication citation), and include a link to the license, and indicate if any changes were made. All articles are distributed under the terms of the Creative Commons Attribution-NonCommercial 4.0 License (CC BY-NC 4.0).

Publishing Ethics and Misconduct

JOC believes in the importance of ethical publishing and ensures that the highest standards of expected ethical behaviour are achieved by all involved parties – the author, the journal editor, the peer reviewers and the publisher – according to the Committee on Publication Ethics (COPE) Ethical Guidelines and the International Committee of Medical Journal Editors (ICMJE) recommendations for the conduct, reporting, editing and publication of scholarly work in medical journals. In cases of suspected publishing misconduct, we undertake all reasonable efforts to ensure that a proper investigation is conducted, as outlined by the COPE Code of Conduct.

According to the World Association of Medical Editors (WAME) (using a slightly amended version of the US Office of Research Integrity), the most common forms of scientific misconduct include the following:

  • Falsification of data: ranges from fabrication to deceptive selective reporting of findings and omission of conflicting data, or willful suppression and/or distortion of data.
  • Plagiarism: the appropriation of the language, ideas, or thoughts of another without crediting their true source, and representation of them as one's own original work.
  • Improprieties of authorship: improper assignment of credit, such as excluding others, misrepresentation of the same material as original in more than one publication, inclusion of individuals as authors who have not made a definite contribution to the work published; or submission of multi-authored publications without the concurrence of all authors.
  • Misappropriation of the ideas of others: an important aspect of scholarly activity is the exchange of ideas among colleagues. Scholars can acquire novel ideas from others during the process of reviewing grant applications and manuscripts. However, improper use of such information can constitute fraud. Wholesale appropriation of such material constitutes misconduct.
  • Violation of generally accepted research practices: serious deviation from accepted practices in proposing or carrying out research, improper manipulation of experiments to obtain biased results, deceptive statistical or analytical manipulations, or improper reporting of results.
  • Material failure to comply with legislative and regulatory requirements affecting research: including but not limited to serious or substantial, repeated, willful violations of applicable local regulations and law involving the use of funds, care of animals, human subjects, investigational drugs, recombinant products, new devices, or radioactive, biologic, or chemical materials.
  • Inappropriate behaviour in relation to misconduct: this includes unfounded or knowingly false accusations of misconduct, failure to report known or suspected misconduct, withholding or destruction of information relevant to a claim of misconduct and retaliation against persons involved in the allegation or investigation.

If our investigations conclude that there is a reasonable possibility of misconduct, the journal will take the necessary steps according to the magnitude of the misconduct. We may retract a publication from the journal in cases of major misconduct. If only a small part of an article reports incorrect information, and especially if this is the result of a genuine error, the journal will publish an erratum, and in some cases, correct the original publication as soon as possible.

To ensure content originality and the highest quality of written work, all articles that are accepted for publication undergo plagiarism detection using iThenticate software.



Conflicts of Interest Policy

JOC recognises that conflicts of interest involving authors, reviewers, editors, and journal staff may arise during the preparation, review, and processing of manuscripts. As defined by the International Committee of Medical Journal Editors (ICJME):

"A conflict of interest exists when professional judgment concerning a primary interest (such as patients' welfare or the validity of research) may be influenced by a secondary interest (such as financial gain). Perceptions of conflict of interest are as important as actual conflicts of interest."

There is nothing inherently unethical about a conflict of interest but it should be acknowledged and openly stated.

Examples of a conflict of interest, as stated by the ICJME, may include, but are not limited to:

  • Financial relationships
            –   Employment
            –   Consultancy
            –   Stock ownership or options
            –   Honoraria
            –   Patents
            –   Paid expert testimony
  • Personal relationships or rivalries
  • Academic competition
  • Intellectual beliefs

Authors should avoid entering into agreements with study sponsors, both for-profit and non-profit, if they restrict authors’ access to all of the study’s data or interfere with their ability to analyze and interpret the data and to prepare and publish manuscripts independently when and where they choose.

Authors, reviewers, editors and journal staff are required to disclose any association that poses or could be perceived as a conflict of interest in connection with a manuscript. Editors, editorial board members, and journal staff are excluded from publication decisions when they are authors or have contributed to a manuscript.

Authors are required to complete the ICJME conflict of interest form to disclose any association that poses or could be perceived as a conflict of interest in connection with the manuscript, and acknowledge all funding sources supporting the work. JOC reserves the right to publish an erratum disclosing a conflict of interest related to a previously published paper.

When invited to evaluate a manuscript, reviewers and editors must disclose any conflict of interest that could bias their opinions of the manuscript. Reviewers must not use knowledge of the work they are reviewing before its publication to further their own interests.

Recent collaborators, defined as people who have coauthored a paper or were a principal investigator on a grant with any of the authors within the past 3 years, must be excluded as editors and reviewers. Other examples of possible conflicts include past or present association as thesis advisor or thesis student, or a family relationship, such as a spouse, domestic partner, or parent–child relationship.

If a conflict of interest is disclosed either by the author or editor, a conflict of interest statement will be included with the published article. Where no conflict of interest is disclosed, the standard text, ‘None declared’ will be published. Cases of suspected undisclosed conflicts of interest will be investigated according to the Committee on Publication Ethics (COPE) guidelines


Withdrawal of Manuscript

If you withdraw your manuscript after it has been peer reviewed or after it has been copy edited or typeset (but not yet published) you will be charged according to the following:

  • For peer review: EUR 250 per article
  • For peer review and typesetting: EUR 550 per article.

If the publisher decides to withdraw an accepted paper for reasons such as plagiarism, fraudulent data/behaviour or other legal issues, the author will not be reimbursed the publication fee.
