Abstract

Advance directives enable people to describe their preferences for medical treatment (living will) and/or to appoint a healthcare proxy who may decide on their behalf should they lose decision-making capacity. Advance directives are potentially important in determining the course of end-of-life care, as deaths are frequently preceded by end-of-life treatment decisions, which often require someone to make decisions on the patient's behalf. Switzerland introduced legally binding advance directives through its new child and adult protection law of 2013. But there is still no comprehensive evidence on older persons' awareness, attitudes and behaviours with regard to advance directives in Switzerland. Our study aimed to assess levels of awareness, approval and completion of advance directives, as well as their respective associations with sociodemographic characteristics in the Swiss population aged 55 and older. Our study was cross-sectional and used data from the Survey of Health, Ageing and Retirement in Europe (SHARE), which included a special module on end-of-life issues in wave 6 (2015) in Switzerland (n = 2085). Two years after the introduction of advance directives in Switzerland, 78.7% of adults aged 55 years and older had heard of them prior to the survey and 24% reported that they had completed one. Awareness of advance directives was higher in the German-speaking part of Switzerland (91%) than in the Italian- (57.1%) and French-speaking (43.3%) regions (p <0.001). Advance directive completion also differed significantly between the German- (28.7%), French- (10.3%) and Italian-speaking (17.9%) regions of Switzerland (p <0.001). Overall, 76.7% of Swiss adults aged 55 and older generally approved of advance directives, i.e., they either reported having already completed one or were planning to do so in the future. Of those who had not yet completed an advance directive, 32.9% believed that it was still "too early" for them to do so and 30.1% believed that they would not need one. Levels of awareness, approval and completion of advance directives also varied significantly by sex, age, education level and household composition. Our results show some potential for improvement in levels of advance directive awareness and, especially, completion among older adults, notably in the French- and Italian-speaking Switzerland. In view of the generally high levels of approval of advance directives, our findings point to important barriers to their completion by older persons that should be addressed by policy makers in order to ensure an effective translation of individual intentions to complete an advance directive sometime in the future into concrete and timely actions toward this end.

Summary

Introduction

Death happens at old age and is most likely to be the consequence of cumulated diseases and functional incapacities during the last years of life. A Swiss study showed that 71% of all deaths that occurred in 2013 in Switzerland were not sudden and were expected [2]. Reich et al showed that, among Swiss people who died between 2007 and 2011 at an average age of 79.3 years, 38% died in a hospital and 35% in a nursing home [3]. The end of life and death often involve making specific treatment decisions, such as forgoing life-prolonging treatment or intensifying the alleviation of symptoms [2]. Cognitive incapacities before death affect at least a quarter of patients [4] and can last several days [5], often leaving patients incapable of making their own end-of-life decisions during this critical life stage
