BMJ Open Diabetes & Research Care is an open access diabetes journal dedicated to publishing high-quality medical research from all disciplines and therapeutic areas of diabetes research, management and treatment. A continuous publication model facilitates rapid publication of basic and clinical research regarding type 1 and type 2 diabetes and associated symptoms, complications, and treatments. The online-only format allows for continuous updates and serves as an invaluable resource to the multidisciplinary community of endocrinology, public health/prevention and internal medicine. All submissions are subject to peer review. Articles should not be under review or under consideration by any other journal when submitted to BMJ Open Diabetes and Research Care.

BMJ Open Diabetes Research & Care is published by BMJ in partnership with the American Diabetes Association.

Editorial policy

BMJ Open Diabetes Research & Care adheres to the highest standards concerning its editorial policies on publication ethics and scientific misconduct. The journal follows guidance produced by bodies that include the Committee on Publication Ethics (COPE), the World Association of Medical Editors (WAME), the Council of Science Editors and the International Committee of Medical Journal Editors (ICMJE). To view all BMJ Journal policies, please refer to the BMJ Author Hub policies page, including information about our Editors’ roles and responsibilities.

Authors are required to submit a statement that their study obtained ethics approval (or a statement that it was not required and why) and that participants gave informed consent. Our Editors will consider whether the work is morally acceptable as determined by the World Medical Association’s Declaration of Helsinki. In addition to this, in line with General Medical Council guidelines, an article that contains personal medical information about an identifiable living individual requires patients explicit consent (in the format of a signed BMJ patient consent form) before we will publish it. Please find further details on BMJ research ethics policies (human participants and animals) and consent for publication; including a link to the downloadable consent form.

To make the best decision on how to deal with a manuscript BMJ Open Diabetes Research & Care needs to know about any competing interests authors may have; this includes any commercial, financial or non financial associations that may be relevant to the submitted article. Authors must download and complete a copy of the ICMJE Conflict of Interest disclosure form. In addition to this BMJ Open Diabetes Research & Care ensures that all advertising and sponsorship associated with the journal does not influence editorial decisions, is immediately distinguishable from editorial content and meets all other BMJ guidelines. Please find more information about competing interests and a link to the form.

We take seriously all possible misconduct.  Anyone with concerns that a submitted article describes something that might be considered to constitute misconduct in research, publication or professional behavior should forward their concerns to the journal. The publisher will deal with allegations appropriately following ICMJE and COPE guidelines. Corrections and retractions are considered where an article has already been published; corrections, expressions of concern or a retraction notices will be published as soon as possible in line with the BMJ correction and retraction policy.

Copyright and authors’ rights

As an open access journal, BMJ Open Diabetes Research & Care adheres to the Budapest Open Access Initiative definition of open access. Articles are published under an exclusive license or non-exclusive license for UK Crown employees or where BMJ has agreed CC BY applies. For US Federal Government officers or employees acting as part of their official duties, the terms are as stated in accordance with our license terms. Authors or their employers retain copyright. Such open access articles can be reused under the terms of the relevant Creative Commons license to facilitate reuse of the content. More information on copyright and authors’ rights.

When publishing in BMJ Open Diabetes Research & Care, authors choose between two licence types – CC-BY-NC and CC-BY (Creative Commons open access licences require payment of an article processing charge). As an author you may wish to post your article in an institutional or subject repository, or on a scientific social sharing network. You may also link your published article to your preprint (if applicable). What you can do with your article, without seeking permission, depends on the licence you have chosen and the version of your article. Please refer to the BMJ author self archiving and permissions policies page for more information.


Preprints foster openness, accessibility and collaboration by allowing authors to make their findings immediately available to the research community and receive feedback on an article before it is submitted to a journal for formal publication.

BMJ fully supports and encourages the archiving of preprints in any recognised, not-for-profit server such as medRxiv. BMJ does not consider the posting of an article in a dedicated preprint repository to be prior publication.

Preprints are reports of work that have not been peer-reviewed; Preprints should therefore not be used to guide clinical practice, health-related behaviour or health policy. For more information, please refer to our Preprint policy page.

Article processing charges

BMJ Open Diabetes Research & Care is an open access journal and levies an Article Processing Charge (APC) of $2,800 (exclusive of VAT for UK and EU authors). There are no submission, color or page charges.

Waivers and Discounts

BMJ journals offer waivers for the full Article Processing Charge (100% discount of the APC) where all authors are based in low-income countries. See full waiver list*.

Requests for waivers should be made before or during initial submission**. If an article reports funding from a funder with an open access mandate or policy that covers paying APCs, BMJ expects that the APC will be paid.

Visit our author hub to learn more about our waivers policy and how to request one.

You might be eligible for institutional funding. A number of institutions have open access agreements with BMJ which can either cover the whole cost of open access publishing for authors at participating institutions or can allow authors to receive a discount of the Article Processing Charge (APC).

Visit BMJ’s open access agreements page to find out whether your institution is a member and what discounts you may be entitled to.

* These lists are based on the HINARI Core Offer Groups A and B, and the World Bank Country and Lending Groups, downloaded in July 2021. They will be updated annually.
**Please note that applications for waivers or discounts should be made during initial submission and not after an article has been accepted. Editors are not involved in this process and the ability to pay has no bearing on editorial decisions. Payment will not be required unless your article is accepted. Accepted articles will not be published until payment has been received. BMJ does not refund APCs once paid.

Provenance and peer review

Submissions to BMJ Open Diabetes Research & Care are unsolicited. All articles submitted are subject to peer review. The journal operates single blind peer review, whereby the names of the reviewers are hidden from the author; usually two external reviewer reports are obtained before an Original research or Review article is accepted for publication. Articles authored by a member of a journal’s editorial team are independently peer reviewed; an editor will have no input or influence on the peer review process or publication decision for their own article. For more information on what to expect during the peer review process please refer to BMJ Author Hub – the peer review process.

BMJ is committed to transparency. Every article we publish includes a description of its provenance (commissioned or not commissioned) and whether it was internally or externally peer reviewed.

BMJ requests that all reviewers adhere to a set of basic principles and standards during the peer-review process in research publication; these are based on the COPE Ethical Guidelines for Peer Reviewers. Please refer to our peer review terms and conditions policy page.
