Social, health and lifestyle-related determinants of older adults' preferences for place of death in South Tyrol, Italy - a cross-sectional survey study

Abstract

Background: As the global aging population expands, understanding older adults' preferences for place of death becomes pivotal in ensuring person-centered end-of-life care.

Objective: This study aimed to investigate the influence of sociodemographic, health, and lifestyle-related factors on end-of-life care preferences of older adults in South Tyrol, Italy.

Methods: Employing a cross-sectional design, a population-based survey was conducted with a stratified probabilistic sample of adults aged ≥ 75 years in South Tyrol (Autonomous Province of Bolzano/Bozen, Italy). From a randomly selected sample of 3,600 older adults, participants were invited to respond to a questionnaire that included items on older adults' preferences for place of death and socio-demographic and health- and lifestyle-related factors, including frailty (e.g., PRISMA-7). Descriptive and multinomial logistic regression analyses were performed.

Results: The majority (55.3%) of the 1,695 older adults (participation rate: 47%) expressed a preference for dying at home and 12.7% indicated a desire for specialized end-of-life care in a healthcare facility. However, 27.9% refrained from disclosing their end-of-life care preferences. The factors influencing these preferences concerning the place of death included age, native language, educational level, living situation, and community. Compared to the preference of dying at own home or home of family or friends, older adults aged ≥ 85 years (OR = 0.57, P = 0.002) and living in an urban area (OR = 0.40, P < 0.001) were less likely to prefer dying at a hospital, palliative care unit, or hospice. Older adults living alone (OR = 1.90, P < 0.001), Italian-speaking (OR = 1.46, P = 0.03), and those with an educational level above high school (OR = 1.69, P = 0.002) were more likely to prefer dying at a hospital, palliative care unit, or hospice.

Conclusions: End-of-life care preferences among older adults in South Tyrol were associated with socio-demographic, yet not health- and lifestyle-related factors. Recognizing and integrating these preferences is essential for developing, implementing, and evaluating interventions to promote advance care planning and provide effective, patient-centered end-of-life care.
