Patient safety is the most reliable measure of the quality of the healthcare system, incomplete or missed healthcare is associated with lower patient safety. The goal of the research was to examine whether there are statistically significant differences in patient safety ratings with regard to the level of education and work experience of the participants, as well as with regard to the participant's workplace and the very impact of missed healthcare on patient safety. Work methods: An online survey was conducted among 100 employed nurses and technicians, in which a questionnaire on the culture of patient safety and questions about missed health care, composed of 69 questions, was distributed online. Results: 60.4% of participants strongly disagree or disagree that they have a problem with patient safety in the department, 42.7% point out that managers respect suggestions, 68.1% strongly disagree or disagree that managers ignore problems , 49% agree or expressly agree that hospital management is interested in patient safety only when reporting adverse events, 41.9% rate patient safety as acceptable. The correlation between patient safety indicators and missed healthcare is not statistically significant (p>0.05). Conclusion: The level of education and workplace of the participants did not have a statistical significance in the ratings of patient safety, while the research showed that nurses and technicians with less seniority pay more attention to patient safety. Missed health care did not have a statistically significant impact on patient safety.
