About the journal
JAMA Surgery (formerly Archives of Surgery) began publication in 1920. It is an international peer-reviewed journal published 12 times a year; the online version is published on the third Wednesday of the month. A Middle Eastern edition of JAMA Surgery is published bimonthly. JAMA Surgery is the official publication of the New England Surgical Society, the Pacific Coast Surgical Association, and the Association of VA Surgeons. The editor envisions the journal as a sounding board and forum for all the changes that are occurring in surgery today, including training paradigms, the 80-hour work week, women and minorities in surgery, malpractice concerns, and universal access to health care. The acceptance rate is 27%. The average time from acceptance to publication is 9 months. Its 2011 impact factor is 4.42 (the impact factor is a measure of citation rate per article, and is calculated by dividing 1 year's worth of citations to a journal's articles published in the previous 2 years by the number of major articles [eg, research papers, reviews] published by that journal in those 2 years). The editor is Julie Ann Freischlag, MD, the William Stewart Halsted Professor and chair of the Department of Surgery at Johns Hopkins Medical Institutions in Baltimore, Maryland.
Mission Statement: To promote the art and science of surgery by publishing relevant peer-reviewed clinical and basic science information to assist the surgeon in optimizing patient care. JAMA Surgery will also serve as a forum for the discussion of issues that involve ethics, teaching, surgical history, and socioeconomic concerns.
Access for Developing Countries: The online version of JAMA Surgery is made freely available or nearly so to institutions in developing countries through the World Health Organization's HINARI program.
Instructions to Authors
Categories of Articles
JAMA Surgery publishes Original Investigations, Reviews, Special Communications, Viewpoints, and other categories of articles. Topics of interest include all subjects that relate to the practice of surgery and the betterment of public health. The most frequently published types of articles are described herein.
Original Investigation
These reports typically include randomized trials (see Clinical Trial), intervention studies, cohort studies, case-control studies, epidemiologic assessments, other observational studies, surveys with high response rates (see Survey Research), cost-effectiveness analyses and decision analyses (see Reports of Cost-effectiveness Analyses and Decision Analyses), and studies of screening and diagnostic tests (see also Reports of Diagnostic Tests). Each manuscript should clearly state an objective or hypothesis; the design and methods (including the study setting and dates, patients or participants with inclusion and exclusion criteria and/or participation or response rates, or data sources, and how these were selected for the study); the essential features of any interventions; the main outcome measures; the main results of the study; a discussion section placing the results in context with the published literature and addressing study limitations; and the conclusions and relevant implications for clinical practice or health policy. Data included in research reports must be original and should be as timely and current as possible (see Timeliness of Data). A structured abstract is required; for more information, see instructions for preparing structured Abstracts. Maximum length: 3000 words of text (not including abstract, tables, figures, references, and online-only material) with no more than a total of 5 tables and/or figures.
Clinical Trial
The ICMJE defines a clinical trial as any research project that prospectively assigns human participants to intervention or comparison groups to study the cause-and-effect relationship between an intervention and a health outcome. Interventions include but are not limited to drugs, surgical procedures, devices, behavioral treatments, process-of-care changes, and the like. All manuscripts reporting clinical trials must include a copy of the trial protocol including the complete statistical analysis plan (see Protocols), a flow diagram (Figure), and a completed trial checklist (see CONSORT Flow Diagram and Checklist). All clinical trials must be registered at an appropriate online public registry (see Trial Registration requirements).
For additional guidance on preparing manuscripts reporting cluster trials, noninferiority and equivalence trials, and pragmatic trials, see Extensions of the CONSORT Statement. Each manuscript should clearly state an objective or hypothesis; the design and methods (including the study setting and dates, patients or participants with inclusion and exclusion criteria, or data sources, and how these were selected for the study); the essential features of any interventions; the main outcome measures; the main results of the study; a discussion section placing the results in context with the published literature and addressing study limitations; and the conclusions. A structured abstract is required, and trial registration information (name, number, and URL) must be listed at the end of the abstract; for more information, see instructions for preparing structured Abstracts. Maximum length: 3000 words of text (not including abstract, tables, figures, references, and online-only material) with no more than a total of 5 tables and/or figures.
Review
These manuscripts are systematic, critical assessments of literature and data sources pertaining to clinical or basic science topics, emphasizing factors such as cause, diagnosis, prognosis, therapy, or prevention. All articles or data sources should be searched for and selected systematically for inclusion and critically evaluated, and the search and selection process should be described in the manuscript. The specific type of study or analysis, population, intervention, exposure, and tests or outcomes should be described for each article or data source. The data sources should be as current as possible, ideally with the search having been conducted within several months of manuscript submission. Meta-analyses also will be considered as reviews. Authors of reports of meta-analyses of clinical trials should submit the PRISMA flow diagram and checklist. Authors of meta-analyses of observational studies should submit the MOOSE checklist. A structured abstract is required; for more information, see instructions for preparing structured Abstracts. Maximum length: 3500 words of text (not including abstract, tables, figures, references, and online-only material) with no more than a total of 4 tables and/or figures and no more than 50-75 references.
Viewpoint
These papers may address virtually any important topic in medicine, public health, research, ethics, health policy, or health law and generally are not linked to a specific article. Viewpoints should be well focused, scholarly, and clearly presented and must have no more than 3 authors. Maximum length: up to 1200 words of text—or 1000 words of text with 1 small table or figure—and no more than 7 references. Viewpoints not meeting these guidelines will not be considered.
JAMA Surgery Clinical Challenge
A JAMA Surgery Clinical Challenge presents a single patient scenario about a specific disease or condition with an accompanying clinical image. Authors should provide 4 single-sentence answers with one of these being preferred for the question “What is the diagnosis?” Manuscripts should include a brief discussion of the relevant clinical issues and provide well-supported explanations discussing the correct diagnosis. The text should have a maximum length of 650 words, consisting of no more than 250 words for the case presentation, question, and 4 answers, followed by no more than 400 words that include the diagnosis and a brief discussion. There should be no more than 3 authors, no more than 10 references, and no more than 3 figures. The image and case presentation should be from the same patient and must not have been published previously. The Patient Permission form must be completed by the patient and included at the time of manuscript submission. All images submitted should be high-quality .jpg or .tif files. Submit the original version of all image files at the highest resolution possible without labels. In general, the original image file should have a minimum resolution of 300 dpi at a width of about 5 inches. Do not increase the original resolution, resize, or crop the image; where applicable, we will crop to maintain patient confidentiality. If any labels, arrowheads, or A/B panel indicators are desired, provide a separate labeled version of the figure(s) for reference. All labels will be retypeset in JAMA Surgery style.
Brief Report: Resident’s Forum
Residents are invited to submit small case series, historical reviews, summaries of recent developments in surgery, and laboratory studies. At the time of submission, the first author must be a resident in training. The submission must be accompanied by a letter from the resident’s program director verifying that the resident is in good standing. Recommended length: 1000-1500 words (not including abstract, tables, figures, references, and online-only material) with no more than a total of 3 tables and/or figures.
Research Letter
Research Letters reporting original research should not exceed 600 words of text and 6 references and may include up to 2 tables or figures. Online supplementary material is not allowed. Research letters may have no more than 5 authors. The text should include the full name, academic degrees, and a single institutional affiliation for each author and the e-mail address for the corresponding author. Other persons who have contributed to the study may be indicated in an Acknowledgment, with their permission, including their academic degrees, affiliation, contribution to the study, and an indication if compensation was received for their role. Letters must not duplicate other material published or submitted for publication. In general, Research Letters should be divided into the following sections: To the Editor (which serves as an introduction), Methods, Results, and Discussion. Research Letters should be double-spaced and a word count should be provided with each letter. They should not include an abstract, but otherwise should follow all of the guidelines in Manuscript Preparation and Submission Requirements. Letters not meeting these specifications are generally not considered.
Letter to the Editor
Letters discussing a recent JAMA Surgery article should be submitted within 4 weeks of the article’s publication. Letters received after 4 weeks will rarely be considered. Letters should not exceed 400 words of text and 5 references, 1 of which should be to the recent JAMA Surgery article. They should be double-spaced and a word count should be provided. Letters may have no more than 3 authors. The text should include the full name, academic degrees, and a single institutional affiliation for each author and the e-mail address for the corresponding author. Letters must not duplicate other material published or submitted for publication and should not include unpublished data. Letters not meeting these specifications are generally not considered. Letters will be published at the discretion of the editors and are subject to abridgement and editing for style and content. Alternatively, comments on papers published in JAMA Surgery can be submitted using the Comments tab on the online article. Comments promote discussion among readers and authors but are not indexed in PubMed.
Letter in Reply
Replies by authors should not exceed 500 words of text and 6 references. They should have no more than 3 authors.
Manuscript Preparation and Submission Requirements
Manuscript Submission
All manuscripts must be submitted online via the online manuscript submission and review system. At the time of submission, complete contact information (affiliation, postal/mail address, e-mail address, telephone and fax numbers) for the corresponding author is required. First and last names, e-mail addresses, and institutional affiliations of all coauthors are also required. 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. After manuscript submission, all authors of papers under consideration for publication will be sent an Authorship Form to complete and submit (see sample Authorship Form). See Manuscript Checklist, Manuscript Preparation and Submission Requirements, and other details in these instructions for additional requirements.

Include a cover letter and complete contact information for the corresponding author (affiliation, postal/mail address, e-mail address, and telephone and fax numbers) and whether the authors have published or submitted any related papers from the same study (see Duplicate/Previous Publication or Submission).
Manuscript Style
Manuscripts should be prepared in accordance with the AMA Manual of Style, 10th edition,2 and/or the Uniform Requirements for Manuscripts Submitted to Biomedical Journals.1
Manuscript Components
Include in the manuscript file a title page, abstract, text, acknowledgments, references, and as appropriate, figure legends and tables. Start each of these sections on a new page, numbered consecutively, beginning with the title page. Figures should be submitted as separate files (1 file per figure or composite figure) and not included in the manuscript text.
Recommended File Sizes
We recommend individual file sizes of no more than 500 kB and not exceeding 1 MB, with the total size for all files not exceeding 5 MB (not including any video files).
Manuscript File Formats
For submission and review, the acceptable manuscript file format is Word. Do not submit your manuscript in .pdf format.
Use 10-, 11-, or 12-point font size, double-space text, and leave right margins unjustified (ragged).
Title Page
The title page should be the first page of your main manuscript file. It should include a manuscript title; the full names, highest academic degrees, and affiliations of all authors (if an author’s affiliation has changed since the work was done, the new affiliation also should be listed); name and complete contact information for corresponding author; and manuscript word count (not including abstract, acknowledgment, or references).
Abstracts
Include a structured abstract of no more than 350 words for reports of original data and meta-analyses. Abstracts should be prepared in AMA style— see instructions for preparing structured abstracts. For other major manuscripts, include an unstructured abstract of no more than 200 words that summarizes the objective, main points, and conclusions of the article. Abstracts are not required for Editorials, Viewpoints, and some special features.
All reports of original data, systematic reviews, and meta-analyses should be submitted with structured abstracts as described below. No information should be reported in the abstract that does not appear in the text of the manuscript.
Abstracts for Reports of Original Data:
Reports of original data should include an abstract of no more than 350 words using the headings listed below. For brevity, parts of the abstract may be written as phrases rather than complete sentences. Each section should include the following content:
Importance: The abstract should begin with a sentence or 2 explaining the clinical (or other) importance of the study question.
Objective: State the precise objective or study question addressed in the report (eg, “To determine whether…”). If more than 1 objective is addressed, the main objective should be indicated and only key secondary objectives stated. If an a priori hypothesis was tested, it should be stated.
Design: Describe the basic design of the study. State the years of the study and the duration of follow-up. If applicable, include the name of the study (eg, the Framingham Heart Study). As relevant, indicate whether observers were blinded to patient groupings, particularly for subjective measurements.
Setting: Describe the study setting to assist readers to determine the applicability of the report to other circumstances, for example, general community, a primary care or referral center, private or institutional practice, or ambulatory or hospitalized care.
Participants: State the clinical disorders, important eligibility criteria, and key sociodemographic features of patients. The numbers of participants and how they were selected should be provided (see below), including the number of otherwise eligible individuals who were approached but refused. If matching is used for comparison groups, characteristics that are matched should be specified. In follow-up studies, the proportion of participants who completed the study must be indicated. In intervention studies, the number of patients withdrawn because of adverse effects should be given. For selection procedures, these terms should be used, if appropriate: random sample (where random refers to a formal, randomized selection in which all eligible individuals have a fixed and usually equal chance of selection); population-based sample; referred sample; consecutive sample; volunteer sample; convenience sample.
Note: The above 3 sections may be combined (as "Design, Setting, and Participants") during the editing process.
Intervention(s) for Clinical Trials or Exposure(s) for observational studies: The essential features of any interventions or exposures should be described, including their method and duration of administration. The intervention or exposure should be named by its most common clinical name, and nonproprietary drug names should be used.
Main Outcome Measure(s): Indicate the primary study outcome measurement(s) as planned before data collection began. If the manuscript does not report the main planned outcomes of a study, this fact should be stated and the reason indicated. State clearly if the hypothesis being tested was formulated during or after data collection. Explain outcomes or measurements unfamiliar to a general medical readership.
Results: The main outcomes of the study should be reported and quantified, including baseline characteristics and final included/analyzed sample. Include absolute numbers and measures of absolute risks (such as increase/decrease or absolute differences between groups), along with confidence intervals (for example, 95%) or P values. Approaches such as number needed to treat to achieve a unit of benefit may be included when appropriate. Measures of relative risk also may be reported (eg, relative risk, hazard ratios) and should include confidence intervals. Studies of screening and diagnostic tests should report sensitivity, specificity, and likelihood ratio. If predictive value or accuracy is reported, prevalence or pretest likelihood should be given as well. All randomized clinical trials should include the results of intention-to-treat analysis, and all surveys should include response rates.
Conclusions and Relevance: Provide only conclusions of the study directly supported by the results, along with a statement of relevance indicating implications for clinical practice or health policy, avoiding speculation and overgeneralization. Indicate whether additional study is required before the information should be used in usual clinical settings. Give equal emphasis to positive and negative findings of equal scientific merit.
Trial Registration: For clinical trials, the name of the trial registry, registration number, and URL of the registry must be included.
Abstracts for Reviews:
Review articles should include an abstract of no more than 300 words with the following sections: Importance, Objective, Evidence Review, Findings, and Conclusions and Relevance.
Importance: Include 1 or 2 sentences describing the clinical question or issue and its importance in clinical practice or public heath.
Objective: State the precise primary objective of the review. Indicate whether the review emphasizes factors such as cause, diagnosis, prognosis, therapy, or prevention and include information about the specific population, intervention, exposure, and tests or outcomes that are being reviewed.
Evidence Review: Describe the information sources used, including the search strategies, years searched, and other sources of material, such as subsequent reference searches of retrieved articles. Methods used for quality assessment and inclusion of identified articles should be explained.
Findings: The major findings of the review of the clinical issue or topic should be addressed in an evidence-based, objective, and balanced fashion, with the highest quality evidence available receiving the greatest emphasis.
Conclusions and Relevance: The conclusions should clearly answer the questions posed if applicable, be based on available evidence, and emphasize how clinicians should apply current knowledge.
Abbreviations
Do not use abbreviations in the title or abstract and limit their use in the text. Expand all abbreviations at first mention in the text.
Units of Measure
Laboratory values are expressed using conventional units of measure, with relevant Système International (SI) conversion factors expressed secondarily (in parentheses) only at first mention. Articles that contain numerous conversion factors may list them together in a paragraph at the end of the Methods section. In tables and figures, a conversion factor to SI units should be provided in a footnote or legend. The metric system is preferred for the expression of length, area, mass, and volume. For more details, see the Units of Measure Conversion Table on the website for the AMA Manual of Style.
Names of Drugs, Devices, and Other Products
Use nonproprietary names of drugs, devices, and other products, unless the specific trade name of a drug is essential to the discussion.
Gene Names, Symbols, and Accession Numbers
Authors describing genes or related structures in a manuscript should include the names and accession numbers provided by the US National Center for Biotechnology Information (NCBI) or the HUGO Gene Nomenclature Committee. Before submission of a research manuscript reporting on large genomic data sets (eg, protein or DNA sequences), the data sets should be deposited in a publicly available database, such as NCBI’s GenBank, and a complete accession number (and version number if appropriate) must be provided in the Methods section or Acknowledgment of the manuscript.
Reproduced Material
Reprinted tables and figures are discouraged. Original material should be provided, except under extraordinary circumstances. Acknowledge all text, illustrations, and tables adapted or reproduced from other publications and submit permission from the original publishers (or other copyright owner) to republish in print and online editions of JAMA Surgery and its licensed versions. (See Permission to Reproduce Copyright-Protected Material Form.)
References
Authors are responsible for the accuracy and completeness of their references and for correct text citation. Number references in the order they appear in the text; do not alphabetize. In text, tables, and legends, identify references with superscript arabic numerals. When listing references, follow AMA style and abbreviate names of journals according to the journals list in PubMed. List all authors and/or editors up to 6; if more than 6, list the first 3 followed by “et al.” Note: Journal references should include the issue number in parentheses after the volume number.

Tables
Number all tables in the order of their citation in the text. Include a title for each table (a brief phrase, preferably no longer than 10 to 15 words). Include all tables at the end of the manuscript file. Refer to Categories of Articles because there may be a limit on the number of tables for the type of manuscript. If a table must be continued, repeat the title on the second page, followed by “(continued).”
Instructions for Table Creation
These instructions are available here.
Figures
Number all figures (graphs, charts, photographs, and illustrations) in the order of their citation in the text. Include a title for each figure (a brief phrase, preferably no longer than 10-15 words). For initial manuscript submissions, figures must be of sufficient quality for editorial assessment and peer review. If the manuscript is accepted, authors will be asked to provide figures that meet the Guidelines for Figures in Accepted Manuscripts. Graphs, charts, titles, and legends in accepted manuscripts will be re-created or edited according to JAMA Surgery style and standards prior to publication. All illustrations of accepted manuscripts will be redrawn by medical illustrators. Online-only figures will not be edited or re-created (see Online-Only Supplements and Multimedia).
Image Integrity
Preparation of scientific images (clinical images, radiographic images, micrographs, gels, etc) for publication must preserve the integrity of the image data. Digital adjustments of brightness, contrast, or color applied uniformly to an entire image are permissible as long as these adjustments do not selectively highlight, misrepresent, obscure, or eliminate specific elements in the original figure, including the background. Selective adjustments applied to individual elements in an image are not permissible. Individual elements may not be moved within an image field, deleted, or inserted from another image. Cropping may be used for efficient image display but must not misrepresent or alter interpretation of the image by selectively eliminating relevant visual information. Juxtaposition of elements from different parts of a single image or from different images, as in a composite, must be clearly indicated by the addition of dividing lines, borders, and/or panel labels.
When inappropriate image adjustments are detected by JAMA Surgery staff, authors will be asked for an explanation and will be requested to submit the image as originally captured prior to any adjustment, cropping, or labeling. Authors may be asked to resubmit the image prepared in accordance with the above standards.
Guidelines for Figures in Accepted Manuscripts:
These guidelines are available here.
Acceptable Figure File Size
To reduce the time that it takes to upload files to the submission site and for reviewers to download files from the site, we recommend that the file size of figures be compressed before uploading them. This can be done by using compression software or by decreasing the resolution of individual files.
Acceptable Figure File Formats
At submission, the following file formats are acceptable: .ai, .bmp, .doc, .emf, .eps, .jpg, .pdf, .ppt, .psd, .tif, .wmf, or .xls. Figures should be submitted as separate files (1 file per figure or composite figure) and not included in the manuscript text.
Figure Legends
Include a legend for each photograph, graph, and illustration at the end of the manuscript (maximum length, 40 words). For photomicrographs, include the type of specimen, original magnification or a scale bar, and stain. Include internal scale markers on electromicrographs. For gross pathology specimens, label any rules with unit of measure. Indicate the method of enhancement for digitally enhanced images.
Digital Enhancement of Images
Digitally enhanced images (CT/MRI, blots, photographs, photomicrographs, ultrasound images, x-ray films, etc) must be clearly identified in the figure legends as digitally processed images. If your manuscript is accepted, you will be asked for 3 clearly labeled print copies of the processed and original images.
Number of Figures
Refer to Categories of Articles as there may be a limit on the number of figures for the type of manuscript.
Online-Only Supplements and Multimedia
Authors may submit supporting material to accompany their article for online-only publication when there is insufficient space to include the material in the print article. This material should be important to the understanding and interpretation of the report and should not repeat material in the print article. The amount of online-only material should be limited and justified. Online-only material should be original and not previously published.
Online-only material will undergo editorial and peer review with the main manuscript. If the manuscript is accepted for publication and if the online-only material is deemed appropriate for publication by the editors, it will be posted online at the time of publication of the article as additional material provided by the authors. This material will not be edited or formatted; thus, the authors are responsible for the accuracy and presentation of all such material.
Online-only material should be submitted in a single Word document (Supplement) with pages numbered consecutively. Each element included in the online-only material should be cited in the text of the main manuscript (eg, "see eTable in the Supplement") and numbered in order of citation in the text (eg, eTable 1, eTable 2, eFigure 1, eFigure 2, eMethods). The first page of the online-only document should list the number and title of each element included in the Supplement.
Online-Only Text
Online-only text should be set in Times New Roman font, 10 point in size, and single-spaced. The main heading of the online-only text should be in 12 point and boldface; subheadings should be in 10 point and boldface.
Online-Only References
All references cited within the online-only document must be included in a separate reference section, including those that also were cited in the main manuscript. They should be formatted just as in the main manuscript and numbered and cited consecutively in the online-only material.
Online-Only Tables
Online-only tables should be inserted in the document and numbered consecutively according to the order of citation as eTable 1, eTable 2, etc. The text and data in online tables should be Arial font, 10 point in size, and single-spaced. The table title should be set in Arial font, 12 point, and bold. Headings within tables should be set in 10 point and bold. Table footnotes should be set in 8 point and single-spaced. See also instructions for Tables above. If a table runs on to subsequent pages, repeat the column headers at the top of each page. Wide tables may be presented using a landscape orientation.
Online-Only Figures
Online-only figures should be inserted in the document and numbered consecutively according to the order of citation as eFigure 1, eFigure 2, etc. Figure titles should be set in Arial font, 12 point, bold, and single-spaced. Text within figures should be set as Arial font, 10 point. Figure legends should be set in 8 point and single-spaced. Graphs and diagrams should be exported directly out of the software application used to create them in a vector file format, such as .wmf, and then inserted into the Word document. Image file formats such as .jpg, .tif, and .gif are generally not suitable for graphs. Photographs, including all radiological images, should be prepared as .jpg (highest option) or .tif (uncompressed) files at a resolution of 300 dpi and width of 3-5 inches, but the resolution of photographic files with an original resolution <300 dpi should not be increased digitally to achieve a 300-dpi resolution. Photographs should be inserted in the document with the "Link to File" button turned off. Wide figures may be presented using a landscape orientation.
