Culturally Adapted Consensus Definition and Action Guideline: Japan's Advance Care Planning.

CONTEXT: A conceptual framework for advance care planning is lacking in societies like Japan's valuing family-centered decision-making. OBJECTIVES: A consensus definition of advance care planning with action guideline adapted to Japanese society. METHODS: We conducted a multidisciplinary modified Delphi study 2020-2022. Thirty physicians, 10 healthcare and bioethics researchers, six nurses, three patient care managers, three medical social workers, three law experts, and a chaplain evaluated, in 7 rounds (including two web-based surveys where the consensus level was defined as ratings by ≥70% of panelists of 7-9 on a nine-point Likert scale), brief sentences delineating the definition, scope, subjects, and action guideline for advance care planning in Japan. RESULTS: The resulting 29-item set attained the target consensus level, with 72%-96% of item ratings 7-9. Advance care planning was defined as "an individual's thinking about and discussing with their family and other people close to them, with the support as necessary of healthcare providers who have established a trusting relationship with them, preparations for the future, including the way of life and medical treatment and care that they wish to have in the future." This definition/action guideline specifically included support for individuals hesitant to express opinions to develop and express preparations for the future. CONCLUSION: Adaptation of advance care planning to Japanese culture by consciously enhancing and supporting individuals' autonomous decision-making may facilitate its spread and establishment in Japan and other societies with family-centered decision-making cultures.

Healthcare Providers' Perceptions on the Timing of Initial Advance Care Planning Discussions in Japan: a Mixed-Methods Study.

BACKGROUND: Most adult patients are willing to discuss advance care planning before the onset of any illness. There might be differences in preferences for timing when it comes to initiating advance care planning discussions by healthcare providers with patients. OBJECTIVE: To identify healthcare providers' willingness to initiate advance care planning discussions in Japan. DESIGN: A mixed-methods questionnaire comprising three case scenarios based on three different illness trajectories. PARTICIPANTS: The study participants were physicians and nurses employed in four community hospitals in Japan. MAIN MEASURES: Percentages of physicians' and nurses' willingness to initiate advance care planning discussions at four stages of patients' illness trajectory were quantitatively determined, and perceptions on preferred timing were qualitatively identified. KEY RESULTS: From 108 physician and 123 nurse respondents (response rate: 99%), 291 physician and 362 nurse responses about three case scenarios were obtained. Overall, 51.2% of physicians and 65.5% of nurses (p < 0.001) accepted discussion before illness. Less than one-third of physicians considered advance care planning a "wise precaution," while about two-thirds of nurses did. Additionally, more than half of both physicians and nurses preferred to postpone advance care planning until the patient's imminent death. CONCLUSIONS: Physicians are less willing than nurses to begin advance care planning discussions before patients' health has deteriorated though most prefer to wait until the patients are close to death. Healthcare providers' attitudes toward advance care planning will need to be addressed to improve rates of completion in Japan.

Patients' preferences and factors influencing initial advance care planning discussions' timing: A cross-cultural mixed-methods study.

BACKGROUND: Although advance care planning discussions are increasingly accepted worldwide, their ideal timing is uncertain and cultural factors may pertain. AIM: To evaluate timing and factors affecting initiation of advance care planning discussions for adult patients in Japan and Taiwan. DESIGN: Mixed-methods questionnaire survey to quantitatively determine percentages of patients willing to initiate advance care planning discussions at four stages of illness trajectory ranging from healthy to undeniably ill, and to identify qualitative perceptions underlying preferred timing. SETTING/PARTICIPANTS: Patients aged 40-75 years visiting outpatient departments at four Japanese and two Taiwanese hospitals were randomly recruited. RESULTS: Overall (of 700 respondents), 72% (of 365) in Japan and 84% (of 335) in Taiwan (p < 0.001) accepted discussion before illness. In Japan, factors associated with willingness before illness were younger age and rejection of life-sustaining treatments; in Taiwan, older age, stronger social support, and rejection of life-sustaining treatments. Four main categories of attitudes were extracted: the most common welcomed discussion as a wise precaution, responses in this first category outnumbered preference for postponement of discussion until imminent end of life, acceptance of the universal inevitability of death, and preference for discussion at healthcare providers' initiative. CONCLUSION: The majority of patients are willing to begin discussion before their health is severely compromised; about one out of five patients are unwilling to begin until clearly facing death. To promote advance care planning, healthcare providers must be mindful of patients' preferences and factors associated with acceptance and reluctance to initiate advance care planning.
