"Advance care planning (ACP) has become widely used in medical care in order to plan ahead of a loss of decision-making capacity. Since ACP aim is to promote anticipatory and substitute autonomy by engaging people ‒ and possibly their relatives ‒ in deciding about future goals of care and treatments, scientific literature in this field often posits that ACP involve shared decision-making. This assumption however is rarely backed up by an in-depth reflection on how shared decision-making might operate within ACP and which shared decision-making template is more likely to foster ACP. Our ACP tool, based on a model created at the Zurich University Hospital (Krones et al, 2019), engages patients in a structured communicational process about their values and preferences for care. In this tool, ACP facilitators help patients set goals of care and document treatments decisions in three paradigmatic situations of loss of decision-making capacity. Because our ACP tool entails discussions about goals of care, quality of life, and options in terms of disease- or symptom-management, we turned to Elwyn and al.’s three talk’s model (2012) and Vermunt et al.’s three level goal model (2018) in order to incorporate elements of shared decision-making in our ACP tool. In this presentation we discuss how these models might be combined in order to foster shared decision-making within our ACP tool and, by then, broaden its scope and eventually improve its effectiveness, strengthen its theoretical foundations and uphold the ethics of care in the event of a loss of decision-making capacity.
