Understanding Employees' Attitudes and Awareness of Code of Ethics and Associated Factors: A Cross-Sectional Survey at a Public Tertiary Hospital in Croatia.

: Ethical challenges in healthcare require awareness and adherence to professional codes of ethics, particularly in interdisciplinary settings such as tertiary hospitals. This study aimed to assess the attitudes and awareness of healthcare professionals regarding codes of ethics at the University Hospital of Split in Croatia, which did not have an institutional code at the time of the study. : A cross-sectional survey using a structured, anonymous questionnaire was distributed both physically across hospital departments and online via email. Welch's -test, ANOVA, Kruskal-Wallis, and correlation tests were used to assess associations between favourability scores and participant characteristics. Linear and logistic regression analyses further examined predictors of favourable attitudes. : Of 442 returned questionnaires, 377 were complete and included in the analysis, mainly from nurses (56.5%) and physicians (42.7%). The median favourability score was 83.8% (88/105; IQR 78.1-88.6), with 87.0% scoring above the favourable threshold (≥75%). Female gender and higher education were significantly associated with more favourable attitudes. Participants strongly endorsed core principles such as patient confidentiality and autonomy, yet 57.6% considered ethics education during training inadequate, and only 36.3% viewed dual practices as a conflict of interest. Most respondents reported adherence to ethical standards (85.4%), while only over half were familiar with their professional ethics code (64.5%) and the hospital Ethics Committee (56.2%); a total of 66.3% supported introducing a hospital-specific code. Awareness and support for ethical structures were higher among women and those with more education. : This study reveals a gap between personal ethical commitment and institutional ethical infrastructure. Strengthening ethics education and implementing a hospital-specific ethics code may enhance organisational ethical culture.
