I'm a staff nurse in an intensive care unit, and we wear scrubs. Mainly blue or green, whatever is available in our linen room (not setting a very good example really-noone knows whether we're surgeons, anaesthetists, sisters, staff nurses,HCSWs or domestics) Our senior sister and charge nurse always wear navy scrubs though. In the main intensive care unit in our hospital (I'm cardiac) they ALL wear navy scrubs. As for the wards in our hospital the Sisters/charge nurses wear navy tunics/epilettes, the staff nurses wear royal blue tunics/epilettes and the health care support workers/(formally known as auxillaries) wear dark green tunics/epilettes. Student nurses wear white tunics with yellow epilettes. But as someone else said it varies from trust to trust.
