There is no single referencing style for nursing. The choice clearly depends on the clinical institutions for Nursing Assignments UK. They commonly use Harvard and Vancouver referencing styles. Harvard is an author-date style used in fields of nursing, midwifery, and some specific healthcare courses. It uses in-text citations with the author’s last name and publication year. In contrast, Vancouver is a numeric style that is commonly used in medical schools and postgraduate research. The method is to write sequential numbers in brackets in the text that refer to a numbered reference list at the end of the assignment.
