Medical and health writing reports evidence precisely and concisely, usually in the IMRaD structure, and cites sources with numbered styles such as AMA or Vancouver. Clarity matters because readers may base clinical decisions on what they read.
This guide covers the conventions of health sciences writing, the assignment types you are likely to meet, the reporting guidelines journals expect, and how to format citations in AMA 11th edition and Vancouver style.
Medical Writing and Its Two Main Citation Styles
Both AMA and Vancouver number sources in the order they are first cited and list them numerically. AMA uses superscript numbers in the text; Vancouver uses superscripts or numbers in brackets, depending on the variant.
Both list up to six authors as surname plus initials without full stops, but they handle longer author lists, books and web pages differently, as the examples below show.
Conventions of Medical and Health Writing
- Precision: give doses, units, time points and measures exactly.
- Evidence-based claims: support each clinical statement with a citation or data.
- Careful causal language: "associated with" for observational findings; "reduced" only where a trial supports it.
- Generic drug names: use the generic name, in lowercase, unless a brand is relevant.
- Patient-centred language: "patients with diabetes" rather than "diabetics".
- Confidentiality: remove anything that could identify a patient in case reports and reflections.
Weak: Vitamin D prevents depression in older people.
Stronger: In observational studies, low serum vitamin D concentrations were associated with higher depressive symptom scores in adults over 65, but trials of supplementation have not shown a consistent benefit.
Common Assignments in Medicine and Health Sciences
| Assignment | Structure or focus |
|---|---|
| Research report | IMRaD: introduction, methods, results, discussion |
| Systematic or literature review | Question, search, appraisal, synthesis |
| Case report or case study | Presentation, investigations, management, outcome, discussion |
| Critical appraisal | Validity, results, applicability of one study |
| Reflective writing | A reflective model applied to a clinical experience |
| Public health report | Problem, population data, intervention options, recommendations |
Writing a Case Report or Case Study
Case reports are one of the most common health assignments and one of the easiest to get wrong. The aim is to describe one patient's care clearly and draw a lesson from it, supported by evidence.
- Introduction: why the case is worth discussing.
- Presentation: history, symptoms and relevant findings, in time order.
- Investigations and diagnosis: tests, results and reasoning.
- Management and outcome: what was done and what happened.
- Discussion: how the case compares with published evidence and guidelines, and what it teaches.
Anonymised presentation: A woman in her seventies presented with two days of increasing breathlessness and ankle swelling. She had a history of hypertension and type 2 diabetes.
The example uses an age band and no names, dates or places. Students should describe only cases they are permitted to use, and never invent clinical details.
Reporting Guidelines
Health journals and many courses expect writing to follow a reporting guideline for its study type. These checklists tell you exactly what a reader needs to judge the work.
| Study type | Guideline |
|---|---|
| Randomised trial | CONSORT |
| Observational study | STROBE |
| Systematic review | PRISMA |
| Case report | CARE |
| Quality improvement | SQUIRE 2.0 |
| Qualitative research | COREQ or SRQR |
Using the checklist while drafting is easier than retrofitting it at the end, and it often reveals missing details early. Many journals ask you to submit the completed checklist with the manuscript.
AMA Style (11th Edition)
AMA style, from the AMA Manual of Style, is used by many medical journals and health sciences programmes.
In-Text Citations
- Use superscript Arabic numerals in order of first citation.
- Place them outside full stops and commas, and inside colons and semicolons.
- Separate several numbers with commas and no spaces, and use a hyphen for a range: 1,3,5-7.
- Reuse a source's number whenever you cite it again.
Reference List
- List authors as surname and initials with no full stops: Okafor CA.
- Give all authors if there are six or fewer; for more than six, list the first three followed by et al.
- Use sentence case for article titles and abbreviated, italicised journal names.
- End journal references with the DOI written as doi:10.xxxx, with no full stop after it.

The examples are illustrative. AMA 11 no longer requires the publisher's city for books.
Vancouver Style
Vancouver is a family of numbered styles based on recommendations from the International Committee of Medical Journal Editors and the US National Library of Medicine's Citing Medicine guide. Universities and journals publish their own versions, so details vary.
In-Text Citations
Number sources in order of first citation, using square brackets, round brackets or superscripts according to your guide: [1], (1) or 1. Reuse numbers for repeat citations.
Reference List
- Authors as surname and initials without full stops, separated by commas.
- Commonly, list the first six authors followed by et al. when there are more than six.
- Journal names abbreviated without italics in the standard NLM form.
- Year;volume(issue):pages with no spaces.

AMA and Vancouver Compared
| Feature | AMA 11 | Vancouver (common form) |
|---|---|---|
| In-text marker | Superscript | Brackets or superscript, by variant |
| More than six authors | First three, then et al. | Commonly first six, then et al. |
| Journal name | Abbreviated, italic | Abbreviated, not italic |
| Book title | Italic, title case | Plain, sentence case |
| Publisher's city | Not required | Included |
| Web pages | Accessed date before URL | [cited date] and "Available from:" |
The free Bibloq citation generator produces AMA and Vancouver references from a DOI or PubMed link, which helps when you need to switch between them.
Finding and Choosing Health Sources
Search PubMed or MEDLINE for medicine, CINAHL for nursing and allied health, and the Cochrane Library for systematic reviews. Prefer systematic reviews and well-conducted trials for questions about treatment, and current national guidelines for practice recommendations.
Check dates carefully. Clinical guidance changes, and an outdated recommendation cited as current is a serious error in health writing. When a guideline has been updated, cite the current version and check whether its recommendation on your topic changed.
Common Mistakes in Medical and Health Writing
- Overstating causal claims from observational studies.
- Using brand names where generic names are expected.
- Including details that could identify a patient.
- Mixing AMA and Vancouver rules, such as italics and author limits.
- Ordering a numbered reference list alphabetically.
- Placing superscript numbers inside full stops in AMA style.

Frequently Asked Questions
Both are numbered styles. AMA uses superscripts, italic journal names and lists three authors before et al. when there are more than six; Vancouver varies by guide but commonly lists six before et al. and uses plain journal names.
Many use Vancouver or AMA; some use APA or Harvard for certain modules. Follow your course handbook.
Outside full stops and commas, inside colons and semicolons.
All authors if there are six or fewer. For more than six, list the first three followed by et al.
Usually not. Vancouver journal names are abbreviated in the NLM form without italics.
Give the author if any, the page title, the website name, the published or updated date, an accessed date and the URL.
The standard structure for research reports: introduction, methods, results and discussion.
Remove names, dates, locations and any combination of details that could identify the patient, and follow your institution's consent rules.
Usually yes, if you follow your programme's confidentiality and consent rules and remove anything that could identify the patient. Ask your tutor if unsure.
