Integrating large language models (LLMs) like GPT-4 into medical ethics is a novel concept, and understanding the effectiveness of these models in aiding ethicists with decision-making can have significant implications for the healthcare sector. Thus, the objective of this study was to evaluate the performance of GPT-4 in responding to complex medical ethical vignettes and to gauge its utility and limitations for aiding medical ethicists. Using a mixed-methods, cross-sectional survey approach, a panel of six ethicists assessed LLM-generated responses to eight (...) ethical vignettes. The main outcomes measured were relevance, reasoning, depth, technical and non-technical clarity, as well as acceptability of GPT-4’s responses. The readability of the responses was also assessed. Of the six metrics evaluating the effectiveness of GPT-4’s responses, the overall mean score was 4.1/5. GPT-4 was rated highest in providing technical (4.7/5) and non-technical clarity (4.4/5), whereas the lowest rated metrics were depth (3.8/5) and acceptability (3.8/5). There was poor-to-moderate inter-rater reliability characterised by an intraclass coefficient of 0.54 (95% CI: 0.30 to 0.71). Based on panellist feedback, GPT-4 was able to identify and articulate key ethical issues but struggled to appreciate the nuanced aspects of ethical dilemmas and misapplied certain moral principles. This study reveals limitations in the ability of GPT-4 to appreciate the depth and nuanced acceptability of real-world ethical dilemmas, particularly those that require a thorough understanding of relational complexities and context-specific values. Ongoing evaluation of LLM capabilities within medical ethics remains paramount, and further refinement is needed before it can be used effectively in clinical settings. (shrink)

BackgroundPatient autonomy is a fundamental, yet challenging, principle of professional medical ethics. The idea that individual patients should have the freedom to make choices about their lives, including medical matters, has become increasingly prominent in current literature. However, this has not always been the case, especially in communist countries where paternalistic attitudes have been interwoven into all relationships including medical ones. Patients’ expectations and the role of the doctor in the patient-physician relationship are changing. Croatia, as a transitional country, is (...) currently undergoing this particular process.MethodsQualitative research was conducted by means of six focus group discussions held in the years 2012 and 2013 in Croatia. Focus groups were held separately with each of the following: first year and final year medical students, physicians engaged in medical ethics education, physicians practicing in a clinical hospital, family medicine residents and individuals representing patients with chronic disease. This research specifically addresses issues related to patient autonomy, in particular, the principles of truth telling, confidentiality, and informed consent. All focus group discussions were audio taped and then transcribed verbatim and systematized according to acknowledged qualitative analysis methods.Results and discussionPatient autonomy is much more than a simple notion defined as the patient’s right to make treatment decisions independently. It has to be understood in context of the broader socio-cultural setting. At present, both patients and medical doctors in Croatia are increasingly appreciating the importance of promoting the principle of autonomy in medical decision-making. However, the current views of medical students, physicians and patients reveal inconsistencies.Conclusions Knowing how to respect the various facets of patients’ autonomy should be part of physician’s professional duties, and also be reflected in his or her core clinical competencies. For this reason greater importance should be dedicated to patient autonomy issues in medical education in Croatia. (shrink)
