BMJ Paediatrics Open is a new open-access journal dedicated to publishing original research, clinical reviews and protocols that deal with any aspect of child health. The provision of child health is multidisciplinary and the journal welcomes papers from all health care professions. Papers dealing with paediatric surgery, paediatric specialties, public health and healthcare provision will all be accepted.

Publication decisions will be made on the scientific validity, ethical soundness and transparency of the research and whether the paper deserves publication, rather than on its apparent interest to any particular readership.

Editorial Policies

BMJ Paediatrics Open adheres to a rigorous and transparent peer review process and all papers will be considered on the basis of ethical and methodological soundness rather than their novelty, significance, or relevance to any particular audience. The journal will be published continuously online and aims to operate a fast submission and review process, to ensure timely, up-to-date research is available worldwide.

BMJ Group editorial policies can be found on our Author Hub. Submissions should be made through the journal’s online submission system. Articles should not be under review by any other journal when submitted to BMJ Paediatrics Open.

Peer Review Process

When a paper has been submitted from the Editor, Deputy or Associate Editors’ departments, they have no role in the reviewing or decision making process. This also applies to any Associate Editors who are authors, in which instance the reviewing process is handled by the Editor-in-Chief.

All articles published in BMJ Paediatrics Open will have been sent for external, open peer review. Upon publication, all previous versions of the manuscript are made available, as are the reviewers’ comments and authors’ replies to those comments. Exceptions are made only when an article is accepted based on reviews received at another BMJ journal and the reviewers have not granted permission for their reviews to be posted online.

Post-publication peer review is encouraged via rapid responses.

Article Publishing Charges

BMJ Paediatrics Open is an Open Access journal and all accepted articles will be liable to an Article Publishing Charge (APC). The standard APC for research articles and reviews will be GBP 1,350 (exclusive of VAT). The APC for protocols will be GBP 1000 (exclusive of VAT).

There is a 25% discount for articles where the corresponding author is an RCPCH member or where the corresponding author has reviewed for BMJ PO within the previous 12 months. These discounts cannot be combined. Further information on discounts or waivers is available here. Editors have no involvement in any decisions around APCs.

There are no submission or page charges, and no colour charges. Payment of the APC may be made online by credit card, or by bank transfer following receipt of an invoice.

Manuscript Transfer

Your article will not automatically be transferred to BMJ Paediatrics Open if rejected from another BMJ Journal; however, you can choose BMJ Paediatrics Open as an alternate journal when submitting an article to any BMJ Journal; any reviewer comments will be shared, resulting in a reduced time to decision.

Manuscripts will be evaluated separately by the BMJ Paediatrics Open editorial team, with different criteria for acceptance.

Data Checks

BMJ is a member of CrossCheck by CrossRef and iThenticate. iThenticate is a plagiarism screening service that verifies the originality of content submitted before publication. iThenticate checks submissions against millions of published research papers, and billions of web content. Authors, researchers and freelancers can also use iThenticate to screen their work before submission by visiting ithenticate.com

Data Sharing

Authors of original research articles are encouraged to include a data sharing statement when submitting their article. The statement should explain which additional unpublished data from the study – if any – are available, to whom, and how these can be obtained.

At present there is no major repository for clinical data, but Dryad has declared its willingness to accept medical datasets. Authors can start the deposition process while submitting to any BMJ Journal. Dryad provides authors with a DOI for the dataset to aid citation and provide a permanent link to the data. Note that Dryad hosts data using a CC0 licence so authors should check that this is suitable for the data that they are depositing. The DataCite organisation has a growing list of other repositories for research data.

Submission Guidelines

For guidelines on submission and editorial policies for BMJ Paediatrics Open please refer to the BMJ Author Hub. Here you will find information on planning your research through to submitting and promoting your research.

Article Types and Word Counts

The word count excludes the title page, abstract, tables, acknowledgements and contributions and the references. Supplementary material (e.g. additional tables, figures and text files) are not included in the word count.

Original Research Article

Word count: up to 2,500 words
Abstract: up to 300 words
Tables/Illustrations: maximum 8 tables and/or figures
References:up to 40 (Systematic reviews that include >25 papers will be allowed more references. We suggest number of included papers + 15)

Word counts may exceed this at the discretion of the editor, but please be aware that exceeding the recommended limit will impact upon the paper’s ‘readability’.

All submissions must contain a box summarising what the article adds to the literature so that readers can gather an overview of the article before reading it. This should be divided into two sections, each with 1-3 sentences and should have the headings:

  • What is known about the subject – followed by a maximum of 3 brief statements (no more than 25 words per statement)
  • What this study hopes to add – followed by a maximum of 3 brief statements (no more than 25 words per statement)

Research submissions should have a clear, justified research question.

All articles should include the following:
  • The article title should include the research question and the study design. Titles should not declare the results of the study.
  • The abstract of an experimental or observational study must clearly state in sequence, and in not more than 250 words, (i) the main purpose of the study, (ii) the essential elements of the design of the study, (iii) the most important results illustrated by numerical data but not p values, and (iv) the implications and relevance of the results.

We require a structured abstract of up to 300 words for reports of randomised controlled trials and meta-analyses, and we encourage it for other studies, where appropriate. The following headings should be used for original research:

  • Objective: clear statement of main study aim and major hypothesis/research question
  • Design: e.g. prospective, randomised, blinded, case control
  • Setting: level of care e.g. primary, secondary; number of participating centres. Generalise; don’t use the name of a specific centre, but give geographical location if important
  • Patients: numbers entering and completing the study; sex and ethnic group if appropriate. Clear definitions of selection, entry and exclusion criteria
  • Interventions: what, how, when and how long (this can be deleted if there were no interventions)
  • Main outcome measures: planned (i.e. in the protocol) and those finally measured (if different, explain why) – for quantitative studies only
  • Results: give numerical data rather than vague statements that drug x produced a better response than drug y. Favour confidence intervals over p values, and give the numerical data on which any p value is based.
  • Conclusions: primary conclusions and their implications, suggest areas for further research if appropriate. Do not go beyond the data in the article
  • Where applicable, trial registration: registry and number (for clinical trials and, if available, for observational studies and systematic reviews)
  • Methods: should be as in the original protocol for the study, which should be submitted as a supplementary file. Where there have been deviations from the protocol, this needs to be justified.
  • Results: should include all the relevant findings. Summarise any data presented in tables. Do not repeat all the information in the tables.
  • Discussion: we recommend, but do not insist, that the discussion section is no longer than five paragraphs and follows this overall structure (you do not need to use these as subheadings): a statement of the principal findings; strengths and weaknesses of the study; strengths and weaknesses in relation to other studies, discussing important differences in results; the meaning of the study: possible explanations and implications for clinicians and policymakers; and unanswered questions and future research.
  • A funding statement: preferably worded as follows. Either: ‘This work was supported by [name of funder] grant number [xxx]’ or ‘This research received no specific grant from any funding agency in the public, commercial or not-for-profit sectors’. You must ensure that the full, correct details of your funder(s) and any relevant grant numbers are included.
  • A competing interests statement: see this advice from the BMJ on what to include.
  • Articles should list each author’s contribution individually at the end; this section may also include contributors who do not qualify as authors. Please visit the ICMJE website for more information on authorship.
  • Any checklist and flow diagram for the appropriate reporting statement, e.g. STROBE (see below).
  • Patient consent form: any article that contains personal medical information about an identifiable living individual requires the patient’s explicit consent before we can publish it. We will need the patient to sign our consent form, which requires the patient to have read the article. This form is available in multiple languages.
  • Please provide a data sharing statement such as: “Technical appendix, statistical code, and dataset available from the Dryad repository, DOI: [include DOI for dataset here].

Authors are encouraged to submit figures and images in colour – there are no colour charges.

BMJ Paediatrics Open does not routinely publish single centre audits but will consider them for publication when the study has genuine implications on wider practice.

Reporting Guidelines

The guidelines listed below should be followed where appropriate. Please use these guidelines to structure your article. Completed applicable checklists, structured abstracts and flow diagrams should be uploaded with your submission; these will be published alongside the final version of your paper.

Protocols

Word count: up to 2,500 words
Abstract: up to 300 words
Tables/Illustrations: maximum 8 tables and/or figures
References: up to 40

Publishing study protocols enables researchers and funding bodies to stay up to date in their fields by providing exposure to research activity that may not otherwise be widely publicised. This can help prevent unnecessary duplication of work and will hopefully enable collaboration. Publishing protocols increases transparency, which makes it easier for others (editors, reviewers and readers) to see and understand any deviations from the protocol that occur during the conduct of the study.

Protocols should report planned or ongoing studies. If data collection is complete, we will not consider the manuscript. The journal will consider protocols for any study design, including observational studies and systematic reviews.

The SPIRIT (Standard Protocol Items for Randomized Trials) statement (see here for details) is an evidence-based tool developed through systematic review of a wide range of resources and consensus. It closely mirrors the CONSORT statement and also reflects important ethics considerations. We encourage investigators to adhere to the SPIRIT recommendations when drafting their protocols.

The PRISMA-P (preferred reporting items for systematic review and meta-analysis protocols) is a new reporting guideline. An article stating the guideline checklist has now been published (see here for details). The PRISMA-P checklist contains 17 items considered to be essential and minimum components of a systematic review or meta-analysis protocol. Systematic review authors and assessors are strongly encouraged to make use of PRISMA-P when drafting and appraising review protocols.

Various other resources exist that list the ingredients of an authoritative trial protocol, e.g. the UK Dept of Health/Medical Research Council Clinical Trials Toolkit and the US National Institutes for Health provide advice on how to structure a trial protocol. BMJ Paediatrics Open will consider for publication protocols for any study design, including observational studies and systematic reviews.

We strongly encourage you to register your study. Prospective registration is mandatory for any clinical trials. Acceptable registries for trials are listed here. We recommend Prospero for registration of systematic reviews.

The journal will consider publishing without peer review protocols that have formal ethical approval and funding from a recognised, open access advocating research-funding body (such as those listed by the JULIET project). Please provide proof that these criteria are met when uploading your protocol. Any protocols that do not meet both these criteria will be sent for external peer review.

General BMJ policies apply (see above) on manuscript formatting, editorial policies, licence forms and patient consent (where applicable to study designs). Protocols should include, as a minimum, the following items.

Protocols should have the following structure:

  • Title: this should include the specific study type, e.g. randomised controlled trial and make clear that the article reports a protocol
  • Abstract: this should be structured with the following sections: Introduction; Methods and analysis; Ethics and Dissemination. Registration details should be included as a final section, if appropriate
  • Introduction: explain the rationale for the study and what evidence gap it may fill. Appropriate previous literature should be referenced
  • Methods and analysis: provide a full description of the study design, including the following: how the sample will be selected; interventions to be measured; the sample size calculation (drawing on previous literature) with an estimate of how many participants are needed for the primary outcome to be statistically, clinically and/or politically significant; what outcomes will be measured, when and how; a data analysis plan
  • Ethics and dissemination: ethical and safety considerations and any dissemination plan (publications, data deposition and curation) should be covered here
  • Full references
  • Authors’ contributions: state how each author was involved in writing the protocol
  • Funding statement: preferably worded in one of two ways: ‘This work was supported by [name of funder] grant number [xxx]’ or ‘This research received no specific grant from any funding agency in the public, commercial or not-for-profit sectors’
  • Competing interests statement

Reviews

Word count: up to 3,000 words
Abstract: up to 300 words
Tables/Illustrations: maximum 8 tables and/or figures
References: up to 40

We welcome submissions of both Practical Reviews (e.g. treatment of the patient with asthma) and systematic reviews which focus on a specific question. For systematic reviews, PRISMA guidelines should be followed and a checklist submitted. In both cases, the Methods section should include a description of the process of literature retrieval.

Practical Reviews should be submitted under the heading of “Review” while Systematic Reviews should be submitted as Original Articles.

Additional information may be placed on the website as a data supplement.

Editorials

Word count: up to 1,200 words
No abstract
No Tables/Illustrations
References: up to 5

Editorials are commissioned by the editorial team and fall into two general categories: comment on particular research papers and comment on wider child health.
