IEEE prints author initials before the surname and abbreviates the periodical title. Check the abbreviation for JAMA against your target publication's reference list before submitting.
APA
Singer, M., Deutschman, C. S., Seymour, C. W., Shankar‐Hari, M., Annane, D., & Bauer, M., et al. (2016). The Third International Consensus Definitions for Sepsis and Septic Shock (Sepsis-3). JAMA, 315(8), 801. https://doi.org/10.1001/jama.2016.0287
APA puts the year directly after the authors, keeps the full journal title in italics, and renders the DOI as a URL.
BibTeX
@article{singer2016,
author = {Mervyn Singer and Clifford S. Deutschman and Christopher W. Seymour and Manu Shankar‐Hari and Djillali Annane and Michael Bauer},
title = {The Third International Consensus Definitions for Sepsis and Septic Shock (Sepsis-3)},
journal = {JAMA},
volume = {315},

pages = {801},
year = {2016},
issn = {0002-9955},
doi = {10.1001/jama.2016.0287}
}The citation key is the first author's surname and the year. Keep it stable once it appears in a draft, because renaming it breaks every cite that used it.
What to verify before you submit
- The volume and page range. JAMA records 354,242 works, and articles published online first can carry a different volume from the final issue. Cite the version you read.
- The abbreviated title. IEEE style uses standard periodical abbreviations, and registry metadata almost always returns the full name instead.
- Author name order. Registry records store full given names; IEEE and APA both want initials, formatted differently from each other.
- Whether the article is open access. This journal is not fully open access, which affects whether a reader can reach the version you cited.
- That the source supports your claim. A correctly formatted reference says nothing about whether the passage backs the sentence citing it.
How this journal sits in the record
JAMA carries an h-index of 1,015, which is above 99% of the journals covered here, and its articles have accumulated 7,625,403 citations across 354,242 indexed works. Its two-year mean citedness is 9.26.
2 of the journals covered here are published by American Medical Association. Reference style is set per title rather than per publisher, so do not carry a format across from a sibling journal without checking.
These are indexing figures describing how often work in this venue is cited. They say nothing about whether a particular article is sound, and they are not a substitute for reading it.
Questions about JAMA
What is the ISSN of JAMA?
The linking ISSN is 0002-9955. The journal also carries 0098-7484 and 1538-3598 and 2376-8118, which usually separate the print and electronic editions. Use the linking ISSN in a BibTeX issn field.
Who publishes JAMA?
American Medical Association publishes it. 2 journals covered here come from the same publisher, and they do not all share one reference style, so check the requirements for this title rather than the publisher.
Is JAMA open access?
OpenAlex does not record it as fully open access. Some articles may still be open individually, so check the specific article rather than assuming from the journal.
How do I cite an article from JAMA in LaTeX?
Use the BibTeX entry above as the pattern. The entry type is article, the journal field holds the full title, and the citation key singer2016 follows the first author's surname and the year. Brace any acronym in the title so your bibliography style does not lowercase it.
Does JAMA use page numbers or article numbers?
The example article runs from page 801, so this journal used page ranges at least for that volume. Newer issues in many journals switched to article numbers, so check the version you are citing.
How influential is JAMA?
Its h-index is 1,015, above 99% of the journals covered here, and its articles have been cited 7,625,403 times in total. Its two-year mean citedness is 9.26. These are indexing figures, not a judgement of whether a specific article is sound.
Does JAMA have a Journal Impact Factor?
Not one shown here. The Journal Impact Factor is Clarivate's metric, published in Journal Citation Reports and readable only with a JCR subscription, so this page does not restate it. The figures above come from OpenAlex: an h-index of 1,015 and a two-year mean citedness of 9.26 across 354,242 indexed works, captured on 2026-09-18. Mean citedness averages citations per work over a two-year window, which makes it closer in construction to CiteScore than to the Impact Factor. The three are not interchangeable, so quote whichever one your target venue actually asks for.
