As a consequence of globalisation, people’s mobility has been increasing, which brought cultural diversity to a number of countries of the world, therefore intercultural competences became a particularly important research object in organisation management. Scientific literature is rich in publications on the topic, however, the latter problem and its specificity has been insufficiently studied in health care organisations whose performance is especially important for each patient and the cost of errors, possibly caused also by insufficient intercultural competences, may be very great. The conducted research justifies the meaning and significance of intercultural competences in health care organisations and identifies the principal problems in organisations faced when communicating in an intercultural environment. The development of intercultural competences was not sufficiently promoted in health care organisations, leaving that to the staff’s responsibility. Quite a few of health care services providers had a poor knowledge of etiquette and did not know much about the customs and traditions of other countries.
