The Canadian Journal of General Internal Medicine (CJGIM) publishes concise papers, which are subject to peer review. The Journal considers articles of original research, reviews, scholarly addresses, case reports, book reviews, historical interest, clinical tips, guidelines, letters to the editor, and so on. Requirements are in accordance with “Uniform requirements for manuscripts submitted to biomedical journals” ( The editorial policies of the journal are in line with those of the Council of Science Editors.

Peer Review

Submissions to the Canadian Journal of General Internal Medicine (cjgim) are subject to double anonymous peer review; no identifying information is shared between the author(s) and reviewers. Letters to the editor, book reviews, and conference abstracts undergo editorial review but are not peer reviewed.

The CJGIM Editor-in-Chief or Deputy Editor first reviews submissions to ensure the content is suitable for peer review and potential publication in the journal based on quality and the editorial contribution the article provides. Once an initial decision is made, the article will be assigned and Associate Editor and continue through to the peer review process or be returned to the author rejected or revised and resubmit.

A minimum of two reviews are required for a decision. Reviewers may make the following recommendations:

  • Accept (no revisions needed)
  • Accept with minor revisions
  • Revise and resubmit for further review
  • Reject

Reviewer comments are anonymously shared with the author(s). Revised articles may be returned for further peer review, or reviewed by the editorial team. The Editor-in-Chief makes the final decision based on reviews.

Upon acceptance, the author is charged the Article Processing Charge (APC). See our Open Access page for more information.

The journal aims to provide authors with a final decision within eight weeks from the time of submission.

Author Submission Guidelines

All cjgim submissions, reviews, and editorial work is done through our online manuscript submission system. Manuscripts are received with the understanding that they are submitted solely to cjgim and that none of the material contained in the manuscripts has been published previously or is under consideration for publication elsewhere, excluding abstracts.

First and last names, email addresses, and institutional affiliations of all coauthors are also required. As part of the acceptance of your work for CJGIM, we also ask you to provide a brief bio and high-resolution photo of the corresponding author (see details regarding illustrations below), your social media handle(s) and a short, 140-character summary that can be shared with followers on Twitter. After the manuscript is submitted, the corresponding author will receive an acknowledgment confirming receipt and a manuscript number. Authors will be able to track the status of their manuscripts via the online system.

Authors must provide the names of 2-3 experts as possible peer reviewers for their submission. These recommendations should not be familiar with the author or submission in order to ensure an ethical double anonymous review.

If the manuscript is accepted, the corresponding author will review an edited manuscript and proof, handle all post-publication communications, and will be identified as the corresponding author in the published article.

The corresponding author is also responsible for ensuring that acknowledgements, funding, conflict of interest and other disclosures, and authorship information is complete and accurate.

Back to top

Conflict of Interest

All authors must disclose any commercial associations or any other arrangements (e.g., financial compensation received, patient-licensing arrangements, potential to profit, consultancy, stock ownership, etc.) that may pose a conflict of interest in connection with the article using the Disclosure of Interest form (PDF). This information will be made available to the editor and reviewers, and will be included as part of the published paper in the disclosure section.

Ethics of Human Experiments


For studies involving human subjects, the Methods section of the manuscript must include a description of the process for obtaining informed consent from participants.

Back to top

Approval by Ethics Review Board

cjgim requires that all studies involving human subjects are conducted ethically, meet the legal requirements of the study country, and are approved by an ethics review board. Authors are accountable for obtaining ethics approval certificates and must certify that approval was secured as part of the submission process. Editors may request documentation of the formal review and recommendations of the ethics review board.

Authors will be required to make a statement to that effect when submitting their manuscript and provide evidence of the ethical/legal approval obtained from the ethics review committee at the institution or practice at which the studies were conducted, where such a committee exists, prior to the research being undertaken.

Back to top

Informed Patient Consent

cjgim respects patients’ right to privacy. Any identifying characteristics or information that might reveal a patient’s identity including names, initials, or hospital numbers, should not be published in written descriptions, photographs, x-rays, MRIs, charts, and pedigrees unless the information is essential for scientific purposes. If human subjects are involved and personal information is essential for scientific purposes, when submitting manuscripts authors must indicate that all patients and/or participants gave informed consent and that the protocol was approved by an ethics review board. For articles containing detailed information about a patient, it is necessary for the patient (or parent, guardian, legal representative or estate) to give written informed consent for publication. Authors should disclose to these patients whether any potential identifiable material or information might be available upon publication. Patient consent should be written and archived with the authors and confirmation that informed consent was obtained will be requested with manuscript submission.

Editorial Conflicts of Interest

Following peer review, final decisions regarding publication are usually made by the Editor-in-Chief. In the event that the Editor-in-Chief has a potential conflict of interest with the manuscript or its authors, there is a recusal process and the manuscript is assigned to an Associate Editor or an alternative member of the editorial team who does not have a conflict of interest related to the manuscript.

In the event that a manuscript is authored or co-authored by a member of the editorial team (i.e., Editorial Board members, Associate Editors, or Editor-in-Chief), the manuscript will be assigned to another editorial team member in order to avoid a conflict of interest. For example, if the Editor-in-Chief is a co-author of a paper for peer review, an Associate Editor will act as the Editor-in-Chief for that paper. The editorial team member who is an author or co-author of a submitted paper will have access to the same information regarding the submitted paper as any non-editorial team author/co-author of any other paper.

Back to top

Publishing Agreement

Following a decision of acceptance, authors will receive author agreements in electronic format. Each author receives and completes a separate agreement. In this agreement, authors transfer copyright to the Canadian Society of Internal Medicine (CSIM). Authors who are employed by a federal government are exempt from this agreement, and instead must submit a copy of the federal governmental office’s copyright license.
