Hence, this study investigates older adults\u2019 perceived and actual knowledge of their partners\u2019 preferences for end-of-life care and medical treatments.<\/jats:p>\n               <\/jats:sec>\n               <jats:sec>\n                  <jats:title>Research Design and Methods<\/jats:title>\n                  <jats:p>We analyzed data from 667 respondents aged 50+ from Wave 8 (2019\/2020) of the Survey on Health, Ageing, and Retirement in Europe in Switzerland. We assessed respondents\u2019 actual knowledge by comparing their perceptions of their partners\u2019 preferences for end-of-life care and medical treatments with the partners\u2019 self-reported preferences. Additionally, respondents were asked to rate their perceived knowledge of their partners\u2019 wishes. Associations were assessed using multivariable regression models, adjusting for social, health, and regional characteristics.<\/jats:p>\n               <\/jats:sec>\n               <jats:sec>\n                  <jats:title>Results<\/jats:title>\n                  <jats:p>Respondents\u2019 actual knowledge of their partners\u2019 preferences varied, with the share of correct answers ranging from 35% to 81% depending on the preferences. More than 80% of respondents felt that they knew their partners\u2019 end-of-life and medical treatment preferences \u201crather\u201d or \u201cvery\u201d well, and those respondents were more likely to identify their partners\u2019 preferences accurately.<\/jats:p>\n               <\/jats:sec>\n               <jats:sec>\n                  <jats:title>Discussion and Implications<\/jats:title>\n                  <jats:p>Improved communication between partners regarding their end-of-life preferences could significantly enhance surrogate end-of-life decision-making. However, since older adults\u2019 perceived knowledge of their partners\u2019 preferences seems overly optimistic, they may see little need to initiate such conversations by themselves, emphasizing the need for external educational interventions such as role-plays or case study discussions through, say, the community, or healthcare system to encourage such conversations.<\/jats:p>\n
