Format AMA 11th Edition Citations for a Nursing Manuscript, Step by Step

Your target journal asks for AMA style, but your reference list is alphabetized and your citations are in author-date form. Converting by hand means renumbering every source in order of first citation. This guide shows the AMA 11 pattern and a worked example first, then the numbering rules, more source types and how AMA differs from APA.

Quick Answer: The AMA 11 Journal Reference

In the text, put a superscript number after the punctuation. In the reference list, number the entries in the order of first citation.

Pattern
1. Lastname AA, Lastname BB. Article title, sentence case only. Abbreviated Journal Title. Year;volume(issue):first page-last page. doi:10.xxxx/xxxxx
Worked example (fictional)
1. Ibarra PL, Voss KD. Nurse practitioner-led follow-up after heart failure discharge: a retrospective cohort study. J Adv Pract Examples. 2022;9(2):210-218. doi:10.xxxx/xxxxx
In text
Early follow-up calls improved attendance.1

What AMA 11 Is and When It Applies

The AMA Manual of Style, 11th edition (2020), is published by the American Medical Association. It is a numeric system: a source receives its number the first time it is cited, and each number leads to an entry in the reference list. Programs that prepare nurse practitioners, and journals that publish clinical research, often ask for it. If your syllabus, project template or target journal names AMA, follow that source wherever it differs from this page. Details that changed from earlier editions include the removal of the publisher's location from book references and the routine use of an "Accessed" date for online sources.

About the examples. Authors, journals and links below are fictional or placeholders, apart from one clearly labeled real textbook. They show the pattern only. Copy the details for your reference list from the sources you actually used.

Numbering in the Text

Structured handoff reduced omitted medication details.1 Early follow-up calls improved attendance,2,3 although the effect varied by clinic.4-6 Other reviews disagree7; the overall evidence is mixed.

Because the number stands in for the author, you may still name an author in a sentence when it helps, followed by the superscript number.

A web page has no italics in its title, and the site name is added after the title when it differs from the author. Guidelines and datasets follow their own patterns; see the guideline guide and the dataset guide.

Formatting Checklist

Common Mistakes

MistakeFix
Alphabetizing a numeric reference listOrder strictly by first citation
Giving a source two numbersReuse the first number
Superscript placed before a periodPut it after periods and commas
Full journal titles in the listUse NLM abbreviations
Adding a city for the publisherLeave it out in the 11th edition

Academic integrity. A numbered citation still has to credit the true source of every idea, and your institution's academic-integrity rules apply. The official rules are in the AMA Manual of Style.

Frequently Asked Questions

Is AMA or Vancouver the safer choice for a manuscript?

Neither. Use whatever the journal or your program names. When neither does, ask your chair or check the journal's author instructions.

Is AMA common in nursing programs?

It appears mostly in nurse practitioner and other clinically focused programs. APA is still the more usual choice in nursing overall, and your program handbook is the deciding source.

Can I write the author name in the sentence?

Yes. The numeral still follows, for example: Voss and colleagues reported a reduction.2
