A qualitative analysis of semi-structured interviews revealed that proxy decision-making in dementia research is influenced by factors such as past experiences, attitudes, and the involvement of other proxies or treating healthcare professionals. These findings provide insights that could improve the decision-making process for proxies and researchers.
Objectives: The benefit-risk ratio of many interventions remains unclear in older adults with dementia. Efforts for more representative trial inclusion are made; however, recruiting and particularly gaining informed consent remains complex. For research participation, dementia compels the designation of a legal guardian (LG) to give proxy consent. To advance future trial development, we aimed to provide more insights into the factors that affect the proxy decision-making process in dementia research. Design: A qualitative analysis of semi-structured interviews about proxy decision-making on participation in dementia research. Setting and Participants: LGs of nursing home residents that gave (n = 19) and refrained from giving (n = 18) proxy consent for a clinical trial (the Danton study) in the Netherlands. Methods: Verbatim transcripts were thematically analyzed by using a preliminary deductive framework with room for induction of additional emerging themes, being an overall abductive approach. Based on that theme list, related factors of the decision-making process were grouped into overarching levels and merged into a step-by-step process. Results: When discussing proxy decision-making on the participation of an older adult with dementia in a clinical trial, LGs described interconnected factors on the level of the study and patient. Past experiences and attitudes of the LG influenced the weighing of these study- and patient-related factors, leading to a preliminary decision. Other proxies and treating health care professionals (HCPs) were named as important other stakeholders of the decision-making process. Conclusions and Implications: When giving proxy consent for research participation, LGs weigh study- and patient-related factors, leading to an initial benefit-risk evaluation. This weighing process is influenced by LG-related factors and can be modulated by other proxies or treating HCPs, leading to a definitive decision. Although insights into these underlying mechanisms could facilitate the proxy decision-making process for both LGs and researchers, treating HCPs could act as an independent party.
