SMJ welcomes quality manuscript submissions from both Singapore and overseas authors. To facilitate a smooth publication process, authors who are considering submitting their manuscripts to SMJ are strongly encouraged to read the following guidelines.

SUBMISSION

To submit a manuscript, please go to www.editorialmanager.com/singaporemedj

If you do not have an SMJ author account on the Editorial Manager, create an account and log in with your username and password. Before uploading your manuscript onto the Editorial Manager, ensure you have all the documents described in the manuscript preparation section.

A one-time, non-refundable Article Processing Charge (APC) is required upon submission. Waiver of the APC applies only to Singapore Medical Association members in good standing, members of the editorial board, and authors whose articles are invited by the editor. In addition, recipients of the SMJ Reviewer Recognition Award from the previous year will enjoy waiver of the APC for the next calendar year (e.g. recipients of SMJ Reviewer Recognition Award 2016 will enjoy waiver of APC for articles submitted between January and December 2017).  

Note: The APC is a non-refundable administrative fee; payment of the APC does not guarantee acceptance of the manuscript.

When the APC has been successfully processed and the submission meets the initial screening, a tracking number will be emailed to the authors, who will be able to track the status of their manuscript online.

All material submitted for publication is assumed to be submitted exclusively to the SMJ unless stated otherwise.
 

REVIEW PROCESS

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. 

Peer Review

Manuscripts that are submitted to the SMJ undergo a double-blinded peer review and are managed online. Please suggest 3-4 individuals who are especially qualified to review this work. Suggested reviewers must not be affiliated with the same institution(s) as any of the authors, or have any potential conflicts of interests in reviewing the manuscript.  

Decisions on manuscripts are made in accordance with the 'Uniform Requirements for Manuscripts Submitted to Biomedical Journals' (www.icmje.org/index.html).

Revision

A request for revision does not guarantee that the paper will be accepted. Reviewers may feel that the paper meets most criteria for publication, but needs clarification on certain areas. Authors are given approximately 12 weeks to return their revised manuscript. Note that if the revision is not received after 6 months, the Editorial Office will consider the paper as ‘withdrawn’.

Two copies of a revised paper should be submitted: an anonymised, tracked copy and a clean copy. A point-by-point reply to reviewers’ and editorial comments should exclude any identification of the authors or institutions, as this letter may be sent to the reviewers for consideration during the second round of peer review.

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 authorised by the corresponding author.

Do note that the Journal does not publish manuscripts without the author's approval of the galley proof and a completed Copyright Form. For this reason, it is vital that a working email address and fax number are provided to the Journal office. Once the author gives approval for publication, the Editorial Office will not be held responsible for any mistakes thereafter. 

Note that with effect from June 2012, the editorial office has stopped sending a complimentary copy of the journal to overseas authors in view of the rising cost of international postage. Instead the corresponding authors of all manuscripts published in the SMJ will receive a high-resolution soft copy of the article upon publication.

Manuscript (2 different copies)

Your submission should consist of versions of your manuscript – 1 anonymised and 1 non-anonymised.

Anonymised version–this version should not contain any information that may identify the authors and their respective institutions. This includes the explicit mention of persons and institutions. The Title page and Acknowledgement section should not be included in this version.

Non-anonymised version– this version should include the title page. Explicit mention of information that may identify the authors and their respective institutions is permitted. This version of the manuscript will be the one used in preparation for print, if it is accepted for publication.

Abstract and Keywords

The Abstract should be an informative synopsis/summary of your manuscript. There are 2 kinds of abstracts: Unstructured and Structured.

Structured – Organise the abstract according to the following headings:

(1)  Introduction – states the purposes/aims of the study/investigation
(2)  Methods – describes the selection of study subjects/experimental animals, observational and analytical methods
(3)  Results – provides specific data and its statistical significance, if possible
(4)  Conclusion – succinct emphasis of new and important aspects of the study or observations

No additional subheadings are required. The word count should not exceed 250 words.

Unstructured – There is no need to divide the abstract into different sections, unlike the Structured abstract. The word count should not exceed 150 words.

Below the abstract, provide a maximum of 5 keywords (or short phrases) that will assist in the cross-indexing of the article. These will be published with the abstract.

Tip: check and confirm that the keywords are the most relevant terms found in the title or the Abstract, and are preferably also listed in the medical subject headings (MeSH) list of Index Medicus found in https://www.nlm.nih.gov/mesh/.

Reference

The Vancouver style of referencing is adopted by the Journal. The detailed style of the different types of citations can be found here.

It is the authors’ responsibility to check all references very carefully for accuracy and completeness. Authors should avoid using abstracts as references. “Unpublished observations” and “personal communications” may not be used as references; if cited, a letter (from the person quoted) granting permission must be submitted. Subject to editorial approval, the person quoted will be cited in parentheses in the text and not in the reference section.

Acknowledgements 

State contributions that need to be acknowledged, but do not justify authorship. Acknowledgeable contributions include (not in exhaustive order) general support by a Department Head or Chairman, technical help, and financial and/or material support (including grants).

LANGUAGE 

SMJ is an English language journal. The use of British English is strongly encouraged. The Editorial Office does not offer major copyediting services; therefore, it is the author's responsibility to ensure that the English language is thoroughly revised before submitting the work for publication. Note that the Editorial Office reserves the right to reject a manuscript if the use of language is deemed too poor.

Authors whose native language is not English are strongly encouraged to seek assistance from a competent linguist who is familiar with medical terminology in order to ensure that the words used convey the intended meaning both accurately and clearly.

PLAGIARISM

Please be advised that all manuscripts submitted to the Journal will be screened for plagiarism using CrossCheck powered by iThenticate. 

The Editorial Office has encountered cases where authors have copied entire paragraphs from previously published articles. Although these passages were duly cited and credited with reference sources derived from the articles, this has been found to be unacceptable by Journal standards. Authors are required to paraphrase all reference citations in their own words. This is necessary to prevent any future misunderstandings regarding plagiarism.

In the rare case where a certain citation would lose its original meaning and essence if paraphrasing is attempted, the Journal requires authors to enclose the citation in quotation marks (“ ”) to indicate that it is a direct quote from the source. However, excessive usage of such quotation marks is discouraged and should be utilised only when absolutely necessary. 

In order to stem out this unethical practice of plagiarism, the Journal adopts a zero-tolerance stance toward wholesale copying of published works. Failure to comply with these instructions will result in the outright rejection of manuscripts without peer review.

  • Provide only strictly pertinent information and references.

DO NOT:

  •  Review the subject extensively.
  •  Include data or conclusions from the work being reported.
     

Methods 
Describe precisely your selection of the observational/experimental subjects (patients, participants or laboratory animals, including controls). Identify the following in sufficient detail, so that there is enough information to reproduce the method presented in the study: 

  • Methods
