The characteristics of patients’ medical care, living will, and signs of death by age and the place of death: A cross-sectional study using a questionnaire survey targeting physicians with expertise in end-of-life care

This dataset contains the complete, de-identified, participant-level data (n = 440) used for the analyses in the associated article. Records were obtained via a structured questionnaire survey and include age at death (years), sex, place of death, medical treatments received near the end of life, presence of a living will, and end-of-life signs observed by respondents. Data are provided as a tidy CSV (one row per patient) with an accompanying data dictionary and README describing variable definitions. The dataset enables replication of the published analyses and supports secondary reuse such as prevalence estimation, development of prognostic models for dying trajectories, and cross-setting comparisons. Direct identifiers have been removed, and quasi-identifiers have been generalized to reduce re-identification risk; only the minimally necessary data are included. Ethical considerations and consent procedures are described in the associated article; the Dryad deposit contains de-identified data suitable for public sharing.
