Wikipedia has a detailed Manual of Style for medicine-related articles.
For student editors, two elements in particular can help avoid commons problems:
- PMID references: for references to sources in PubMed, be sure to include the PMIDs within the citations. This ensures that other editors will be able to easily track down the sources themselves.
- Recommended article sections: for the common types of medicine-related articles — diseases and disorders, drugs and devices, surgeries and procedures, signs and symptoms, elements of anatomy, medical tests, etc. — there are typical sections (in a typical order) that are recommended. For new articles, or expansion of existing articles, students should take these standard organizational patterns as starting points.
