For most nurses world-wide, activities are centred around working directly with patients and so the nurse-patient relationship is of the greatest importance. Ethnocentrism on the part of the health care community has led to misdiagnosis, mistreatment and undertreatment of culturally diverse individuals world-wide. This author discusses a tool, Greipp's Model of Ethical Decision-Making, which can be used to assist nurses in analysing the effects of culture, beliefs and diversity upon the caregiver and care recipient within an ethical framework.
