Vancouver is a numbered referencing style: each source gets a number the first time you cite it, and you reuse that same number every time you cite it again. The reference list at the end is ordered by number — in the order sources first appear in your text, not alphabetically. It's the standard style for nursing, medicine and many health and life-science courses across UK universities. This guide covers how to apply it correctly, with worked examples.
Vancouver is one of the most logical styles once the core idea clicks: numbers replace author names in the text, and the list follows citation order. The catch is keeping the numbering consistent as you edit and reorder a long document.
How Vancouver works
- The first source you cite becomes 1, the second 2, and so on.
- Each number is shown either in brackets (1) or as a superscript¹ — check your university guide for which.
- If you cite source 1 again later, it stays 1.
- The reference list is numbered in citation order, so reference 1 is the first source you cited anywhere in the text.
In-text citations
Single source:
Handwashing remains the most effective infection-control measure (1).
Citing the same source again later — reuse the number:
As noted earlier, compliance varies by ward (1).
Multiple sources at once — use a range or list:
Several studies support this (2-4). ... Others disagree (5,7).
With a direct quotation — add a page number:
Compliance was described as "highly variable" (1 p23).
Place the citation number right after the relevant statement, before or after the full stop according to your university's guide — then be consistent.
The reference list
Head it References. List sources numerically in citation order (not alphabetically). Vancouver uses a specific, compact format with minimal punctuation and standard journal abbreviations.
Journal article:
Author AA, Author BB. Title of article. Abbreviated Journal Name. Year;Volume(Issue):page-page.
Example:
Smith AB, Jones CD. Hand hygiene compliance in acute wards. Br J Nurs. 2020;29(4):210-215.
Note: author initials follow the surname with no full stops; list up to six authors, then "et al." for seven or more; journal names are abbreviated (e.g. Br J Nurs for British Journal of Nursing).
Book:
Author AA. Title of book. Edition. Place of publication: Publisher; Year.
Example:
Dougherty L, Lister S. The Royal Marsden Manual of Clinical Nursing Procedures. 10th ed. Oxford: Wiley-Blackwell; 2020.
Chapter in an edited book:
Author AA. Title of chapter. In: Editor BB, editor. Title of book. Edition. Place: Publisher; Year. p. xx-xx.
Webpage:
Author/Organisation. Title of page [Internet]. Place: Publisher; Year [cited Year Month Day]. Available from: URL
Example:
National Institute for Health and Care Excellence. Infection prevention and control [Internet]. London: NICE; 2023 [cited 2026 Mar 12]. Available from: https://www.nice.org.uk/...
Authors and "et al."
- List up to six authors in full.
- For seven or more, list the first six followed by "et al."
- Author format is surname then initials, no full stops, no "and" or "&": Smith AB, Jones CD, Patel RK.
The mistakes that lose marks
- Alphabetising the reference list — Vancouver is in citation order, not alphabetical. This is the single most common error.
- Renumbering errors after editing — moving a paragraph changes citation order; the numbers must be updated to match.
- Inconsistent brackets vs superscript — pick the format your university uses and apply it everywhere.
- Full stops in author initials — Vancouver uses none (AB, not A.B.).
- Spelling journal names out in full when your guide wants standard abbreviations (or vice versa).
- A source cited but missing from the list, or numbered out of sequence.
Renumbering is exactly where long nursing dissertations go wrong — every reorder risks breaking the sequence. Our Formatting & Referencing service, led by health-specialist editors, re-sequences and rebuilds Vancouver reference lists so every number matches.
A workflow that keeps Vancouver consistent
- Use a reference manager (EndNote, Zotero, Mendeley) for Vancouver — manual renumbering across a long document is error-prone.
- Do your major reordering before finalising references so the sequence settles.
- Check brackets vs superscript against your university guide once, then apply throughout.
- Final pass: confirm every in-text number has a matching reference and the list runs in unbroken citation order.
- Proof the manager's output — abbreviations and author formatting often need correcting.
The bottom line
Vancouver is logical: numbers in citation order, reused on repeat, listed numerically at the end. The discipline it demands is keeping that sequence intact while you edit. Get the numbering right and the format consistent, and Vancouver protects the easy marks that catch out so many health students.

Frequently asked questions
Is the Vancouver reference list alphabetical? No — it's in numerical citation order, matching the order sources first appear in your text. Alphabetising it is the most common Vancouver mistake.
Brackets or superscript for the numbers? Both exist. Check your university's guide and apply one consistently throughout your document.
How many authors do I list before "et al."? List up to six authors in full; for seven or more, list the first six then "et al."
What if I cite the same source twice? Reuse its original number every time. A source keeps the number it was first assigned.
Do I abbreviate journal names? Usually yes — Vancouver uses standard journal abbreviations (e.g. Br J Nurs). Check your guide, as some departments ask for full titles.
