Introduction:
The study aimed to analyse the knowledge of and attitudes towards patients' rights among healthcare professionals.

Materials and methods:
100 physicians and 100 nurses. Mean age: 40 years (min. 24, max. 64, SD: 9.390), mean length of service of the respondents: 15 years (min. 1, max. 44, SD: 10.569, median: 13). Diagnostic survey, voluntary and anonymous questionnaire developed by the authors, 46 questions Quantitative and qualitative analysis, STATISTICA 10.0, Mann-Whitney U test, p<0.05.

Results:
34% assessed their knowledge of patients' rights as good (p<0.011). 19% of the physicians and 7% of the nurses assessed their knowledge as very good. 85% of the study participants knew the right to information, right to access medical records, and right to health services (p=NS). 78% were familiar with the Act on Patients' Rights and Ombudsman for Patients' Rights. 64% of the total confirmed that they had witnessed the infringement of patients' rights at their workplace.

Conclusions:
1. The knowledge of the study participants concerning patients' rights was insufficient. Therefore, a system of trainings for medical personnel in this field needs to be developed and introduced. 2. Healthcare professionals play a minor role in providing patients with information on their rights. Hence, medical personnel should have an opportunity to acquire knowledge, skills and competence in this area. 3. Due to the fact that a majority of the respondents witnessed the infringement of patients' rights, the observance of patients' rights by healthcare professionals needs to be monitored and those who infringe patients' rights should be held professionally responsible.
