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)

Prenatal screening, consisting of maternal serum screening and nuchal translucency screening, is on the verge of expansion, both by being offered to more pregnant women and by screening for more conditions. The Society of Obstetricians and Gynaecologists of Canada and the American College of Obstetricians and Gynecologists have each recently recommended that screening be extended to all pregnant women regardless of age, disease history, or risk status. This screening is commonly justified by appeal to the value of autonomy, or women's (...) choice. In this paper, I critically examine the value of autonomy in the context of prenatal screening to determine whether it justifies the routine offer of screening and the expansion of screening services. I argue that in the vast majority of cases the option of prenatal screening does not promote or protect women's autonomy. Both a narrow conception of choice as informed consent and a broad conception of choice as relational reveal difficulties in achieving adequate standards of free informed choice. While there are reasons to worry that women's autonomy is not being protected or promoted within the limited scope of current practice, we should hesitate before normalizing it as part of standard prenatal care for all.

Sex selection technologies have become increasingly prevalent and accessible. We can find them advertised widely across the Internet and discussed in the popular media—an entry for “sex selection services” on Google generated 859,000 sites in April 2004. The available services fall into three main types: preconception sperm sorting followed either by intrauterine insemination of selected sperm or by in vitro fertilization ; preimplantation genetic diagnosis, by which embryos created by IVF are tested and only those of the desired sex are (...) transferred to the woman's uterus; and prenatal testing of fetuses through ultrasound or chromosomal analysis, followed by selective abortion of fetuses detected to be of the undesired sex.

Lors de l’atelier organisé dans le cadre de l’atelier et du forum communautaire 2023 de la SCB-SCB, nous avons exploré et problématisé le concept d’ « amélioration » des éthiciens cliniques, dans le contexte plus large des discussions sur la professionnalisation de l’éthique clinique. Ce résumé présente les principaux points de vue d’éthiciens cliniques à travers le Canada sur ce sujet et comprend des suggestions sur les mesures que nous pourrions prendre sur le terrain pour permettre et soutenir l’amélioration des (...) éthiciens cliniques à l’avenir.

Jennifer Bell applies Susan Sherwin's theory of relational autonomy as a lens to qualitative health research to study patient decision-making in cancer clinical trials. Interestingly, her broader goal is to enhance patient decision-making in the healthcare context1 rather than the research one. This goal relies on a silent assumption that knowledge gained in a research context is easily transferable to the healthcare context. It also leaves unexplored the promise—and peril—of the application of her work in a research context.Bell's goal to (...) develop tools to enable, maintain, or support patient autonomy skills in...
