Validity and reliability of the integrated palliative care outcome scale (IPOS) in Korea: a multicenter study of terminally ill cancer patients.
Article in BMC palliative care, 2024. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 6 papers.
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
backgroundThe Integrated Palliative care Outcome Scale (IPOS) is a key tool for assessing the quality of palliative care using patient-reported outcomes. This study aimed to culturally adapt and translate the IPOS to Korean and verify its psychometric properties for use in palliative care settings.
methodsThe IPOS was translated and culturally adapted, followed by validation in 119 terminally ill cancer patients and 28 healthcare providers across six Hospice and Palliative Care Units from September 2023 to January 2024. Reliability was assessed using internal consistency, test-retest reliability, and inter-rater reliability. Concurrent validity was assessed using Spearman's correlation coefficients between the IPOS items and the corresponding EORTC QLQ-C15-PAL and the corresponding FACIT-Sp-12.
resultsThe Korean IPOS demonstrated good internal consistency, with Cronbach's alphas of 0.74 for patients and 0.81 for staff. The test-retest reliability showed moderate-to-good stability, with an intra-class correlation coefficient of 0.722 for the IPOS total score. Concurrent validity was supported by moderate correlations with the European Organization for Research and Treatment of Cancer Quality of Life Questionnaire Core 15 Palliative Care (EORTC QLQ-C15-PAL) and Functional Assessment of Chronic Illness Therapy-Spiritual Well-being Scale (FACIT-Sp-12). Known-group validity was demonstrated by significant differences in the IPOS scores across Phase of Illness.
conclusionThe Korean IPOS is reliable and valid for assessing palliative care outcomes. This validation supports its use in clinical practice and research and provides a robust framework for evaluating and improving palliative care delivery in Korea.
