RQ: Personal excellence of nursing focusing on self-transcendence and achievements is crucial for achieving excellence in health care. The question is whether there is unequal treatment of patients despite high ethical standards placed in health care.Purpose: Professional nurses code is a guide in assessing their ethical performance. People are different amongst each other, but have the same rights in the health system, which should be provided by health care services. The need to overcome inequalities has become a cornerstone of excellence in health care.Method: A small quantitative survey of nurses was conducted in one of the departments in a Slovenian hospital. To analyse the results, we used frequency statistics, Spearman's rank correlation test and chi-square test. Results: Providers of health care services are aware of the importance of ethics in its formation. Professional Code is relatively well known; 8.4 % of the respondents were not sure if they clearly define the principles of respect for equality. Discrimination, caused by providers of health care, is of a less extent. Ethical awareness among health care providers does not affect identification with the profession. The education level ofnursing personnel and the perception of discrimination based on religious affiliation influenced one another. Education has no influence on the perception of discrimination based on other circumstances.Organization: Health care organizations should integrate hygieneethical thinking among its strategic goals. Quality is not only quantifying the data. Personal excellence of health care providers, which is difficult to measure, is the basic building block of organizational excellence and patient satisfaction.Originality: There are not many research studies on perceptionsof discrimination in health care. The article raises the sensitive issue that we should talk more about.Limitations: The survey was conducted on a small sample size. Further research should be conducted on perception of discrimination of both sides in health care, both in terms of health care providers as patients. It may be worthwhile to compare the differences in the perception of discrimination in private and in public hospitals.
