Japanese Version of the Quality of Dying and Death in the PICU Instrument: Development and Validation in Eight Centers in Japan.
Article in Pediatric critical care medicine : a journal of the Society of Critical Care Medicine and the World Federation of Pediatric Intensive and Critical Care Societies, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
objectivesThe quality of dying and death (QODD) of children on the PICU is essential for them, their families, and carers at the end-of-life. Currently, there are no standard instruments for measuring QODD in PICUs in Japan (J). We have developed a Japanese version of PICU-QODD (PICU-QODD-J) instrument, which has been culturally adapted to the Japanese context, and evaluated its psychometric validity.
designThe study comprised two phases: 1) development of the PICU-QODD-J instrument, conducted with input from experts, clinicians, and bereaved families and 2) a multicenter, prospective, cross-sectional validation involving PICU clinicians. Data for the validation phase were collected between May 2023 and June 2024.
settingEight PICUs in Japan.
participantsWe recruited 231 clinicians (112 physicians, 119 nurses) who provided end-of-life care for 65 children in the PICU and their families.
interventionsNone. MEASUREMENTS AND MAIN
resultsThe PICU-QODD-J instrument was developed through forward-backward translation, reviewed by a panel of five experts, and evaluated by 12 clinicians and seven bereaved family members. The PICU-QODD-J instrument comprises 21 items and demonstrated acceptable internal consistency (Cronbach's α = 0.92) and good test-retest reliability with intraclass correlation coefficient of 0.77 (95% CI, 0.64-0.85). The inter-rater reliability (IRR) was low (0.09 [95% CI, 0.06-0.13]). Standardized PICU-QODD-J instrument scores showed moderate positive correlations ( r = 0.42-0.57; p < 0.001) with evaluations of overall quality of end-of-life care, quality of the moment of death, and fulfillment of family needs, supporting good construct validity.
conclusionsThe PICU-QODD-J instrument demonstrated good reliability and validity and can be used to assess and improve end-of-life care in PICUs in Japan. However, given the low IRR, evaluations should be interpreted from multiple perspectives rather than a single assessment.
