Clinical Trial Summary

The XPHI-COVID-2 randomized study aims to investigate the moral choices in a context of scarce resources. The participants are asked to complete the questionnaire of the Oxford Utilitarianism Scale and are exposed to medical triage dilemmas. Participants are randomized between a group with reading of ethical guidelines and a group without reading of ethical guidelines, before they are asked to complete the questionnaire and being exposed to triage dilemmas.


Description:

It is hypothesized that recalling ethical values before resolving dilemmas could modify the ability to adopt a utilitarian approach in resolving ethical dilemmas. To verify this hypothesis, the score on the Impartial Harm subscale of the Oxford Utilitarianism Scale (IH-OUS) will be compared between a group with reading of ethical guidelines and a group without reading of ethical guidelines, before they are asked to complete the questionnaire and being exposed to triage dilemmas. Number of subjects needed for the phase of study evaluating intensivists, anesthesiologists and emergency physicians : 580 - based on preliminary data, assuming 70% complete response rate of the survey and a standard deviation of 5 Secondary outcomes will be considered : - Beneficence Harm subscale of the Oxford Utilitarianism Scale (IB-OUS) - Values prioritized to resolve ethical dilemmas : impartial of benefits, prioritization of the young age, saving life years, saving most lives, equality of treatment, prioritization of the worst off, loyalty duty, principle of non-discrimination, prospective and retrospective instrumental value. First phase of the study will aim to include first-line caregivers : intensivists, anesthesiologists, emergency physicians. Other phases of the study will aim to include health care professionals from other categories and non health care professionals. Subgroup analyses are planned : - Analysis according to the characteristics of the participant: gender, geographic location, diploma and type of exercise, category of institution to which the participant is attached. - Analysis according to the degree of knowledge in ethics, the degree of familiarity with ethical recommendations, the degree of familiarity with moral philosophy, the degree of religiosity, whether the participants declare to have taken knowledge or not of recommendations concerning medical triage in a situation of scarce resources. It is also planned to carry out ancillary studies in parallel with the realization of the study presented here: - A study including non-physician participants aiming to identify the differences between non-physicians and physicians in terms of ethical values mobilized in medical triage. - A study including medical students aiming to identify an association between propensity to make utilitarian and choices of the medical specialty. - A study focused on the Oxford Utilitarianism Scale, integrating the results of the pilot study and the confirmatory study, aiming to identify predictors of responses to the dilemmas proposed within the scale. - A study evaluating the association between delay in ethical dilemmas resolution and utilitarian choices.

Outcome

Type Measure Description Time frame Safety issue
Primary IH-OUS score Score on the Impartial Harm subscale of the Oxford Utilitarianism Scale (IH-OUS) : minimum value is 4 points and maximum value is 28 points.
The higher the value is, the more the participant's choices endorse the principle of causing harm to bring the greater good.
At the end of the inclusion period
Secondary Utilitarian score One point is given for each choice consistent with utilitarian principles when solving triage dilemmas, scaling this score from 0 to 14. At the end of the inclusion period
Secondary IB-OUS score Score on the Instrumental Beneficence subscale of the Oxford Utilitarianism Scale (IB-OUS) : minimum value is 5 points and maximum value is 35 points.
The higher the value is, the more the participant's choices endorse the impartial maximization of the greater good, even at the cost of personal self-sacrifice.
At the end of the inclusion period
Secondary Oxford utilitarianism scale Bi-dimensional scale of utilitarian thinking associating the impartial harm and the beneficence subscale. The minimum value is 9 points and the maximum value is 63 points.
This scale aims to assess the utilitarian tendencies in people who are not philosophy professionals.
At the end of the inclusion period
Secondary Impartial of benefits Principle of impartial assignment of resources used in resolving ethical dilemmas.
The value will be considered as respected by the majority of participants if more than 50% of respondents make a choice of a patient in accordance with this value.
At the end of the inclusion period
Secondary Prioritization of the young age Propensity to prioritize the youngest person in ethical dilemmas. The value will be considered as respected by the majority of participants if more than 50% of respondents make a choice of a patient in accordance with this value. At the end of the inclusion period
Secondary Saving life years Propensity to save the most life years in resolving ethical dilemmas. The value will be considered as respected by the majority of participants if more than 50% of respondents make a choice of a patient in accordance with this value. At the end of the inclusion period
