Design: Semi-structured interviews were conducted with 10 individuals with experience in surrogate decision-making for an older adult family member. Methods: The recorded interview data were transcribed verbatim, divided into minimum semantic units, and coded. Next, categories and subcategories were abstracted. A comparison was made with the conceptual constructs of a previous study that examined decision-making by families in a life-threatening crisis. Results: Four categories were extracted from 489 antecedents, 370 attributes, and 388 consequences. One new category was abstracted for each of: 1) antecedents: observing abnormalities and responding, while being worried about death;2) attributes: deliberating on the patient prognosis, the relationship with the patient, and what they believe the patient would want;and 3) consequences: continuing support during convalescence. It is desirable to provide support based on the characteristics of families of older adults, including considering the psychological burden on the families who make surrogate decisions, and also the burden of subsequent caregiving because it is not and in the present environment has not been common for patients to express their wishes beforehand.展开更多

The purpose of this study was to investigate the relationship between incidents of heat-related illness and the daily maximum temperature. Methods: The daily maximum temperatures in Japan's 11 districts over the past 10 years were classified into four categories, with cutoff points at the 50th, 75th, 95th, and higher than 95th percentiles. We then conducted a logistic regression analysis of einergency transportation demand in each temperature category by age group, using the 50th percentile as tile reference category for each area. Results: There were 42,931 cases of emelgency transportation due to heat-related diseases during the study period. Classified by age. 12.5%, 43.4%, and 44.1% of cases involved children, adults, and elderly people, respectively. The analysis showed that the number of cases of emergency transportation for people with heat-related diseases (per 100,000 people; corresponding to a 1.0~C increase in the daily maximum temperature) was 0.016-0.106 among children (24.9-169.9 children required emergency transportation for heat-related diseases), from 0.013 to 0.059 among adults (19.8 98.2 adults required emergency transportation), and from 0.045 to 0.159 among elderly persons (30.0 145.4 elderly people required emergency transportation). The risk was highest for elderly persons, followed by children and finally adults. Cases of emergency transportation due to heat-related illness increased by 2.4-8.9 times when the daily maximum temperature was approximately 1.5℃ above the mean daily maximum temperature. In fact, the daily maximum temperature had a larger effect than the daily relative humidity level oil emergency transportation for people with heat-related diseases. Conclusion: Public health organizations and health-care services should support elderly people and children, two high-risk groups for heat-related diseases.展开更多
