Research and Publication ethics

Caribbean Medical Journal strives to stringently adhere to all the core principles of research and publication ethics. This ensures not only strengthening of its trust with the readership but also promoting high quality scientific publications which have a sound ethical background

Any form of scientific misconduct is abhorred by the journal.

Duties of Authors

The following are the ethical requirements of the journal:

  1. All research papers submitted to CMJ must have a statement that it was approved by an Institutional Review Board / Ethics Committee. For clinical trials, any registry information and/or Approval ID number from the IRB must be included.
  2. Where informed consent is applicable, the paper must explicitly state that either informed consent was obtained from individual subjects or a ‘waiver’ of consent was approved by the IRB
  3. Case Reports must have a statement that informed consent was obtained from the patient or legal representative
  4. There should be a meticulous attempt to exclude any protected health and confidential information; photographs must be edited to avoid displaying the identity of the patient
  5. The corresponding author must assume the responsibility for the data as well the paper submitted, and any form of academic misconduct such as falsification, fabrication, using other’s data without permission, plagiarism of any kind will not be tolerated.
  6. Plagiarism of any type will not be permitted – by definition plagiarism is claiming someone else’s work as one’s own. Caribbean Medical Journal follows COPE Retraction Guidelines. Any act of plagiarism will lead to the rejection of submitted material or – if already published – to the retraction of the corresponding paper. The Editorial Board reserves the right to verify each work through the test of plagiarism and if the same occurs to notify the author.
  7. Duplication of submission to different journals, whether in total or in part, including ‘salami’ publications (previously published papers modified with a little new information to convert it into a new paper) are also not permitted.
  8. Publications in the form of Abstracts, Conference Proceedings are acceptable (from the same study), but this must be notified during submission.
  9. If the journal editorial team (or the peer-reviewer, or if the journal receives a complaint at a later date) finds any academic misconduct, the journal will investigate the matter, if found true the paper will be retracted and the authors will be blacklisted for future submissions 
  10. Authorship criteria (hyperlink) must be strictly adhered to for naming a person as an author and any discrepancy at a later date will not be entertained
  11. The covering letter must explicitly state the contribution of each author, and that there is no conflict of interest between the authors and all authors have approved the final version
  12. The covering letter must also state that the paper is an independent work of the authors and permission was obtained for material borrowed from other sources (if any) and also the source has been explicitly quoted in the paper.
  13. When an author discovers a significant error or inaccuracy in his/her own published work, it is the author’s obligation to promptly notify the journal editor or publisher and cooperate with the editor to retract or correct the paper.
  14. The Author(s) warrant that their manuscript is their original work that has not been published before; that it is not under consideration for publication elsewhere; and that its publication has been approved by all co-authors, if any, as well as tacitly or explicitly by the responsible authorities at the institution where the work was carried out. The Author(s) affirm that the article contains no unfounded or unlawful statements and does not violate the rights of others. If copyrighted works are included, the Author(s) bear the responsibility to obtain written permission from the copyright owners. The Corresponding author, as the signing author, warrants that he/she has full power to make this grant on behalf of the Author(s).
  15. If the author detects an error in the published paper is obliged to instantly inform journal editors or publishers and that as soon as possible the same document. The author shall, in the event of an error, cooperate with the editorial board to remove the same.

Duties of Reviewers


Any manuscripts received for review must be treated as confidential documents. They must not be shown to or discussed with others except as authorized by the editor.


Reviews should be conducted objectively. Personal criticism of the author is inappropriate. Referees should express their views clearly with supporting arguments.


Any selected referee who feels unqualified to review the research reported in a manuscript or knows that its prompt review will be impossible should notify the editor and excuse himself from the review process.

Contribution to Editorial Decisions

Peer review assists the editor in making editorial decisions and through the editorial communications with the author may also assist the author in improving the paper.

Acknowledgment of Sources

Reviewers should identify relevant published work that has not been cited by the authors. Any statement that an observation, derivation, or argument had been previously reported should be accompanied by the relevant citation. A reviewer should also call to the editor’s attention any substantial similarity or overlap between the manuscript under consideration and any other published paper of which they have personal knowledge.

Disclosure and Conflict of Interest

Privileged information or ideas obtained through peer review must be kept confidential and not used for personal advantage. Reviewers should not consider manuscripts in which they have conflicts of interest resulting from competitive, collaborative, or other relationships or connections with any of the authors, companies, or institutions connected to the papers.

Duties of Publisher

All the decisions of the Editorial boards are made independently, without any external pressure or influence, and are fully independent from the publisher.

Editors are responsible for all the processes that the manuscripts submitted to Caribbean Medical Journal will go through. Within this framework, ignoring the economic or political interests, the decision-makers are the editors.
