How to Write a Harvard Referencing for Medicine

Medicine students must navigate a complex landscape of clinical trials, systematic reviews, and multi-author laboratory reports that require precise attribution to ensure patient safety and evidence-based integrity. Unlike general humanities, Harvard referencing in medicine demands specific attention to corporate authors like the WHO and the nuances of citing electronic medical databases.

What Is a Harvard Referencing in Medicine?

In the medical field, Harvard referencing is an author-date system used to link clinical findings and physiological theories to their original empirical sources. It differs from other fields by prioritizing the currency of medical data and frequently requiring the citation of large collaborative research groups or government health departments rather than individual theorists.

Before You Start

• Identify whether you are citing a primary clinical trial, a secondary meta-analysis, or a medical textbook.
• Locate the Digital Object Identifier (DOI) for all journal articles found via PubMed or Embase.
• Check if the source is a 'corporate author' like the Royal College of Physicians or the NHS.
• Verify the specific edition of medical manuals, as clinical guidelines change significantly between versions.
• Differentiate between the print publication date and the 'epub ahead of print' date.

Format In-Text Citations for Single Authors

When referencing a specific medical theory or finding within your text, include the author's surname and the year of publication in parentheses.

Example: The pathophysiology of insulin resistance is closely linked to chronic inflammation (Petersen).

Tip: Place the citation before the period at the end of the sentence discussing the medical condition.

Citing Two or Three Authors

For studies conducted by small teams, list all surnames in the citation to give proper credit to the lead investigators.

Example: Recent observations suggest that beta-blockers may reduce mortality in heart failure patients (Smith and Jones).

Tip: Use 'and' in the text but you may use an ampersand '&' inside the parentheses depending on your specific faculty handbook.

Handling Four or More Authors (Et Al.)

Medical papers often have dozens of contributors. Use 'et al.' after the first author's name in the text to keep the clinical discussion concise.

Example: The efficacy of the mRNA vaccine was confirmed in a large-scale phase III trial (Polack et al.).

Tip: Always ensure 'et al.' is italicized as it is a Latin abbreviation for 'et alia'.

Referencing Corporate Medical Bodies

When citing clinical guidelines or public health statistics, the author is often an organization rather than an individual.

Example: Global obesity rates have tripled since the late twentieth century (World Health Organization).

Tip: On first mention, write the full name; you can use the acronym in subsequent citations if defined.

Citing Journal Articles in the Reference List

Include the author, year, article title, journal name in italics, volume, issue, and page numbers.

Example: Kumar, P. and Clark, M. Clinical Medicine. The Lancet, 395(10222), pp. 12-14.

Tip: Medical journal titles should be written in full unless your specific guide requests NLM abbreviations.

Referencing Medical Textbooks

List the author, year, title in italics, edition (if not the first), place of publication, and publisher.

Example: Guyton, A.C. and Hall, J.E. Textbook of Medical Physiology. 13th ed. Philadelphia: Elsevier.

Tip: Always check the edition, as physiological ranges and drug dosages are updated frequently.

Citing Online Clinical Databases

For dynamic resources like UpToDate or the British National Formulary (BNF), include the 'accessed' date.

Example: Joint Formulary Committee. British National Formulary. [Online] Available at: https://bnf.nice.org.uk/ [Accessed 12 May].

Tip: Since drug interactions are updated regularly, the access date is critical for pharmacological accuracy.

Listing Systematic Reviews

Treat systematic reviews from the Cochrane Library as journal articles, ensuring the specific review number is included if applicable.

Example: Jefferson, T. et al. Physical interventions to interrupt or reduce the spread of respiratory viruses. Cochrane Database of Systematic Reviews, (1).

Tip: Cochrane reviews are high-level evidence; ensure the 'Review' status is clear in your bibliography.

Common Mistakes to Avoid

• Using 'et al.' in the final reference list (most Medical Harvard styles require listing all authors up to a certain limit).
• Confusing the 'online publication date' with the 'print issue date' for medical journals.
• Failing to capitalize medical conditions named after people (e.g., Parkinson's disease).
• Omitting the DOI, which is essential for tracking clinical data in digital medical libraries.
• Citing Wikipedia or non-peer-reviewed blogs for anatomical or pharmacological facts.

Pro Tips

• Use a reference manager like EndNote or Zotero, but set the output style specifically to 'Harvard (British Medical Journal)' if available.
• When citing a drug dose, always cross-reference the BNF to ensure the source you are citing is not outdated.
• If a medical paper has no clear author, use the name of the journal or the sponsoring medical association.
• Keep a separate folder for PDFs of every paper you cite so you can quickly verify page numbers during the final proofread.
• Check if your medical school prefers the 'Author-Date' system or the 'Vancouver' system, as Harvard is less common in surgery but common in nursing and general medicine.

Frequently Asked Questions

How do I cite the BNF in Harvard style?

Cite the Joint Formulary Committee as the corporate author, followed by the year, the title 'British National Formulary' in italics, and the URL with your access date.

When should I use et al. in a medical essay?

Use 'et al.' in the body of your essay whenever a source has four or more authors to maintain the flow of your clinical argument.

Do I need to include the issue number for medical journals?

Yes, because many medical journals are published weekly or monthly, the issue number is vital for locating the specific clinical trial or case study.

How do I cite a secondary source in medicine?

Avoid this where possible by finding the original trial. If necessary, cite it as: (Original Author, cited in Secondary Author).
