Family perceptions of clinical research and the informed consent process in the ICU.

PURPOSE:We investigated experiences of families who provide consent for research on behalf of a loved-one hospitalized in intensive care (ICU). METHODS:Multicentre, qualitative, descriptive study using semi-directive interviews in 3 ICUs. Eligible relatives were aged >18 years, and had provided informed consent for a clinical trial on behalf of a patient hospitalized in ICU. Interviews were conducted from 06/2018 to 06/2019 by a qualified sociologist, recorded and transcribed. RESULTS:Fifteen relatives were interviewed; average age 50.3 ± 15 years. All emphasized their interest in clinical research, seeing it as a duty. Involving their loved-one in research allowed them to find meaning in the events. Participants underlined that trust in caregivers and communication are determinant. The strict regulation of research was perceived as a guarantee of safety. Participants felt they lacked the intellectual capacity and knowledge to question explanations. The greatest fear was not that they might incur a risk for the patient, but rather, that they might deprive the patient of a chance at a cure. CONCLUSION:Acceptance of research opportunities by relatives on behalf of decisionally-incapacitated patients is underpinned by trust in the physicians and the legislative framework. Communication and the quality of information provided by the caregivers are key.
