As a student in the Faculty of Health Sciences, you are bound by the rules in use for the School which offers your degree. The School of Clinical Medicine (MBBCh) uses Vancouver style.
Ethical honesty is taken very seriously by the Faculty of Health Sciences. If you do not acknowledge the source of your information, you might be accused of plagiarism. This can lead to student disciplinary action, such as suspension, or expulsion.
A citation is a reference to a published or unpublished source. A citation style is a standarized description of an item, such as a book or journal, that conforms to a particular format. Usually the formats are created by professional organizations, such as the International Committee of Medical Journal Editors (ICMJE) or publishers, such as the University of Chicago.
Every piece of written work you submit must contain properly cited references, and the list of sources you have consulted must be correctly listed in either style.
This includes portfolios and clinical assessments, as well as Power Point presentations.
Note that NONE of the styles used in MS Office Word conform to the Vancouver Style. You can not therefore use this feature when listing medical citations.
