End-of-Life Treatment Preferences and Related Factors Among People with Dementia: Internet Survey by Bereaved Families, Physicians, Nurses and Care Workers

Abstract

Objective: The aims of this study were to (i) clarify whether there are differences between bereaved families and medical staffs in their preferences for life-prolonging treatments, and (ii) investigate the factors associated with preferences for life-prolonging treatments. Methods: Cross-sectional internet survey was conducted in October 2019. Participants are bereaved families(n=618), physicians(n=206), nurses(n=206), and care workers(n=206) who registered with the internet survey company. We asked the subjects about the relative importance of 36 components of a good death in dementia and their preferences for 7 treatment items that they might need at the end of life. Results: Statistically significant differences in end-of-life medical preference between bereaved families and medical professionals included “Nutrition from gastrostomy when oral intake is difficult” (p<0.01), “Surgery for life-threatening disease” (p<0.01). As a result of logistic regression analysis, a surrogate decision-maker among bereaved family members tended to wish intravenous infusion (OR: 1.62, p=0.02) and continuation of oral medicine (OR: 1.74, p<0.01). The medical professionals who regarded good relationships with people as a requirement of good end-of-life care tended to wish surgery (OR: 2.15, p<0.01) and life-prolonging treatment (OR: 2.00, p=0.01). Conclusions: This result suggest that since the medical preferences between medical staff and the family members don’t necessarily correspond, medical professionals need to take it into consideration when they discuss the treatment options.
