Background Moral sensitivity and academic integrity discernment hold paramount importance for healthcare professionals. Owing to distinct undergraduate educational backgrounds, nurses and physicians may exhibit divergent moral perspectives, academic integrity cognisance, and moral sensitivity within clinical environments. A limited number of studies have investigated the disparities and congruencies pertaining to moral sensitivity and academic ethical awareness among nursing and medical students. Objective The study compares moral sensitivity and academic ethical awareness of undergraduate nursing and medical students with and without clinical exposure. (...) Research design A self-administered cross-sectional survey conducted from January to February 2022 was used to collect data from a medical school in Hong Kong. Participants and research context A total of 545 respondents, including 137 nursing students and 408 medical students, completed the questionnaire. Ethical consideration Ethics approval of the study was obtained. Written consent was waived to maintain anonymity because completing the questionnaire was considered implied consent. Findings Both groups of undergraduates demonstrated a high level of bioethics knowledge. In terms of academic integrity, medical students were found to have a less concerned attitude towards punctuality, attendance, and skipping classes. Regarding moral sensitivity, senior medical students with clinical experience put less emphasis on decision-making involving patient participation, while senior nursing students were more hesitant in withholding treatment for incompetent patients who refused treatment. Both nursing and medical students showed decreased moral sensitivity in the ‘conflicts’ domain with increased clinical exposure. Conclusion Study findings contribute to the discussion comparing the ethical attitudes of nursing and medical students. More effort should be made in nursing and medical education to promote practices in line with high academic integrity and to develop the ability to be morally sensitive in professional settings.
