History of Journal

The Siriraj Medical Journal is a double-blinded peer-reviewed, an open access scholarly journal that has been published by the Faculty of Medicine Siriraj Hospital, at Mahidol University, Bangkok, Thailand. Since 1948, the journal has been introduced to the academia under the name of “Siriraj Hospital Gazette”. In 2007, the journal had been converted into English version and the title was changed to “Siriraj Medical Journal”. The title of the journal (Siriraj) is quite well known both in Thailand and in the East Asia region as it’s the name of the oldest and biggest medical school in Thailand.  It is named after the king's 18-month-old son, Prince Siriraj Kakudhabhand, who had died from dysentery a year before the opening of the hospital. The medical school was established two years later in 1890. The SMJ has published more than 70 issues continuously for the past 70 years. (frequency 10-12 articles per issue).

Peer Review Process

The quality of the articles published in Siriraj Medical Journal depends on the care the reviewers take in establishing that an article is of scientific repute.  Two reviewers are asked to comment on each original article, and occasionally a third reviewer is asked for a further opinion.  As reviewers’ comments are confidential and, equally, as the article to be referred to is confidential, it should not be discussed with colleagues or with the authors.

Open Access Policy

This is an open access journal which means that all content is freely available without charge to the user or his/her institution. Users are allowed to read, download, copy, distribute, print, search, or link to the full texts of the articles, or use them for any other lawful purpose, without asking prior permission from the publisher or the author. This is in accordance with the BOAI definition of open access.

Publication Ethics

Siriraj Medical Journal accepts the World Medical Association Declaration of Helsinki Ethical Principles for Medi­cal Research Involving Human Subjects (Seoul, 2008). Thus, for any new research project involving human research subjects, the authors need to submit a photocopy of a document of approval from Institutional Review Board (IRB) or Institutional Ethics Committee (IEC).

For any research project involving human research subjects starting before 1 March 2009 that does not have a docu­ment of approval from IRB or IEC, the authors need to convince the editorial board that the research does not violate any ethical concern on human research subjects. In addition, for any new clinical trial starting from 1 March 2009, the authors need to register at the public clinical trial registry prior to the research conduct. The registration number should be placed at the end of the abstract in parentheses. 

The ethics for publication is required for a high quality of publication in Siriraj Medical Journal (SMJ). It is therefore important to agree upon standards of expected ethical behavior for all parties involved in the act of publishing: the author, the peer reviewer, and the journal editors. The publication ethics guidelines are followed by the Committee on Publication Ethics- (COPE).

Ethics of Authors

The authors should ensure that they have written entirely original works, and if the authors have used the work and/or words of others that this has been appropriately cited or quoted. Authors should acknowledge ideas and previously published results by citing these works in the paper and listing them in the references. The Journal reserves the right to use plagiarism detecting software to screen submitted papers at all times.

Accuracy: Authors of papers that report on original research should present an accurate account of the study performed as well as an objective discussion of its significance. Underlying data should be represented accurately in the paper which presented the results clearly, honestly, and without fabrication, falsification or inappropriate data manipulation. Conclusions should be based on the evidence presented in the paper and not on personal opinions.

Disclosure of financial support and conflicts of interest: All financial support for the research and the paper writing process should be disclosed in the acknowledgments and any conflicts of interest should be stated. Examples of potential conflicts of interest that should be disclosed include employment, consultancies, stock ownership, honorarium, paid expert testimony, patent applications/registrations, and grants or other funding. Potential conflicts of interest should be disclosed when the article is submitted.

Ethics of Reviewers

Confidentiality: Reviewers should respect the confidentiality of the review process. They should not discuss aspects of the work under review with other researchers until such time as the article is published. Unpublished materials disclosed in a manuscript under review must not be quoted or referenced by a reviewer without the express written consent of the author, requested through the editor. Information or ideas obtained through peer review must be kept confidential and not used for personal advantage.

Conflicts of interest: If the reviewer realizes, after receiving a manuscript for review, that he or she has been involved in the research described, knows the researchers involved in the research, or for any reason cannot give an objective review of the manuscript, the reviewer should inform the editors and decline the review. Conflicts of interest can include competitive, collaborative, or other relationships or connections with any of the authors, companies, or institutions connected to the paper under review.

Objectivity: Manuscripts should be reviewed objectively in the context of the reviewer's expertise in the field. The importance of the article's contribution to the existing research in its field, the quality of articulation of the argument, and the strength of the evidence provided are critical factors in reviewing the quality of a manuscript. Personal opinions without backing evidence should not be used as criteria for review decisions.

Acknowledgment of sources: Reviewers should identify important relevant published work that has not been cited by the authors. 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.

Ethics of Editors

Confidentiality: The editors of Siriraj Medical Journal (SMJ) use a "double-blind" peer review process where neither the authors nor the reviewers know each other's identity. The editors make all best efforts to protect the identity of author(s) and reviewers throughout the review process. Unpublished materials disclosed in a submitted manuscript must not be quoted or referenced by an editor without the express written consent of the author. Information or ideas obtained through peer review must be kept confidential and not used for personal advantage.

Conflicts of interest: Editors recuse themselves from the review process when they have a conflict of interest or personal stake in the publication of research work.

Objectivity: Decisions on publication are made objectively after reviewing the submitted manuscript and the peer reviews. The importance of the article's contribution to the existing research in its field, the quality of articulation of the argument, and the strength of the evidence provided are critical factors in the decision to publish.

Publication Decisions

The journal will not accept articles which have been published (except in the form of an abstract) or are being considered for publication by another journal. Papers being considered here should not be submitted to other journals. 

Editorial Review Process

All submitted manuscripts must go through rigorous Editorial checks before they are sent for peer review. The manuscripts are checked for grammar & language, plagiarism and format. Manuscripts that do not pass the initial checks will be promptly rejected without peer review. 

The editor of Siriraj Medical Journal (SMJ) is responsible for deciding which of the articles submitted to the journal should be published. The editor may be guided by the policies of the journal's editorial board and constrained by such legal requirements as shall then be in force regarding libel, copyright infringement and plagiarism. The editor may confer with other editors or reviewers in making this decision.


Intellectual property is seriously concerned by the Journal. On submission, all articles are screened using the software ‘Turnitin’ which is supported by Mahidol University. Plagiarism is suspected when the percentage of similarity is higher than 20%. The Editor-in-Chief will be informed. Clear plagiarism (use of large portions of copied text and/or data) results in rejection while minor copying of short phrases leads to a polite notification to the authors for re-writing. If plagiarism is detected during the reviewing process by any means, all the processes will be immediately withheld. The Editor-in-Chief will contact the corresponding author and/or all the authors for an explanation. Rejection of submission will occur once the explanation is unsatisfactory or the authors admit guilt. After publication, the article will be retracted if plagiarism is proven. All the authors’ institutions will be contacted to explain the retraction and inform the expected future behaviors. The event of retraction will be officially announced as early as possible in the Journal. 

SMJ Publication Process

The journal policy is generally to publish the articles chronologically according to the acceptance dates. Each accepted manuscript will be formatted in accordance with the journal style. The Editor retains the right to determine the style, and if necessary, edit and shorten any material accepted for publication.

When the galley proof is ready, the Editorial Office will send the proof to authors to check for its completeness. Confirmation or comments from the authors must be given within 48 hours of receipt of the proof, in order to avoid delays in publication of the manuscript. Authors should note that major alterations to the text will not be entertained at this stage and they are responsible for all statements made in their work, including changes made by the Editorial team and authorized by the corresponding author.

Do note that the Journal does not publish manuscripts without the author's approval of the galley proof. For this reason.  Once the author gives approval for publication, the Editorial Office will not be held responsible for any mistakes thereafter. 


Manuscript Rejection: Causes and Remedies

• Lack of Novelty, originality, and presentation of obsolete study. 
• Improper rationale. 
• Unimportant and irrelevant subject matter. 
• Flaws in methodology. 
• Lack of interpretations. 
• Inappropriate or incomplete statistics. 
• Inappropriateness for the journal.


Conflicts of Interest


Authors are required to declare any and all conflicts of interest—financial, personal, or other—that may affect the information, research, analysis, or interpretation presented in the manuscript in the structured disclosures section in every Article, Research Report, Scholarly Perspective, Innovation Report, Literature Review, Invited Commentary, and Letter to the Editor published in Siriraj Medical Journal. A conflict of interest exists when professional judgment concerning a primary interest may be influenced by secondary interests. This information will be held in confidence by the editor-in-chief, unless the manuscript is accepted, in which case a general description of the conflict, provided by the author, will be published with the article. In general, authors should err on the side of disclosing a potential conflict of interest if there is a question about whether a relationship or interest should be disclosed.


Reviewers and editors are required to declare any and all potential conflicts of interest. If an author of a manuscript under consideration has a primary appointment at the editor-in-chief's institution, decisions regarding that manuscript will be made by the deputy editor or an associate editor. If an author has a primary appointment at a deputy editor's or associate editor's institution, that deputy editor or associate editor will not be involved in the decision regarding that manuscript. If the editor-in-chief is an author of a manuscript under consideration, decisions regarding that manuscript will be made by the chair of the Journal Oversight Committee.

Editorial Board

An editorial board is appointed by the editor-in-chief to provide guidance and advice to the editor-in-chief regarding journal content and editorial focus. Each member of the Siriraj Medical Journal Board is expected to (1) present unbiased, independent, and professional advice to the editor-in-chief, (2) maintain confidentiality about editorial board activities and discussion, and (3) sign a disclosure form to affirm that he or she has read, understands, and agrees to abide by the conflict of interest policy and to disclose any known conflicts or to state that no conflicts exist at the time. Conflicts of interest must be disclosed to the editor-in-chief who will determine how to manage, reduce, or eliminate the conflict.
