A Nurse-led Patient-centred Intervention to Increase Written Advance Directives

Background and rationale: Since 2013, with the new Swiss Adult Protection Law, Anticipated Directives (ADs) have been used to identify patients' wills in case they cannot express them later. This instrument is considered to improve care quality, reduce conflicts in decisions between patients, relatives and healthcare teams and utilisation of health resources. Despite their perceived utility, political and institutional campaigns have failed to make ADs common among the population. Discussing life threatening diseases evolution and end-of-life (EOL) issues remains difficult for patients, relatives and professionals. Several interventions were developed to improve advance care planning (ACP) and lead to ADs. However, most of them are cognitively demanding or requiring high levels of literacy. People in 'early stage palliative care' (i.e. with chronic degenerative conditions) could benefit from a simple, adjusted, and acceptable intervention to address the problem outside the hospital setting before the crisis and the appearance of other complications. For a dialogue about EOL to take place, it is necessary to engage in a trustful therapeutic relationship constructed on favourable care conditions. The intervention with a serious card game (Go Wish) is a patient-centred approach developed to help people discuss their wishes of EOL care and to formalize them in ADs. Compared to previous interventions, it has some major advantages: it is accessible (no literacy barriers), it is specific (it is centred on the needs and wishes about care priorities), and it is adaptable depending on how patients feel ready to engage in such discussions. And most important of all, it is compatible with the Terror Management theory (TMT) that provides explanations on reluctance to write ADs and how to work around this problem. The TMT is a theoretical rationale that posits that death thoughts, occurring during EOL care discussions, operates as barriers by creating an existential anxiety and d
