Assessment of the efficacy of palliative sedation in advanced cancer patients by evaluating discomfort levels: a prospective, international, multicenter observational study.
Observational study in BMC medicine, 2024. The graph could read no effect estimate from its abstract, so it casts no vote on the map. It is linked to trial NCT04719702 (Palliative Sedation Across European Settings), which is not on this 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.

Abstract
backgroundPalliative sedation involves the intentional proportional lowering of the level of consciousness in patients with life-limiting disease who are experiencing refractory suffering. The efficacy of palliative sedation needs to be monitored to ensure patient comfort. The aim of this study was to evaluate the efficacy using discomfort levels combined with sedation/agitation levels.
methodsIn this prospective observational study, adult patients with advanced malignancies were recruited from hospice units, palliative care units, and hospital wards in five European countries. Health care professionals used proxy observations of discomfort levels (Discomfort Scale-Dementia of Alzheimer Type, range 0-27) and sedation/agitation levels (Richmond Agitation-Sedation Scale modified for palliative care inpatients), range - 5 to + 4) to evaluate the efficacy of palliative sedation.
resultsIn 78 participants, discomfort levels were monitored during palliative sedation. The mean discomfort score before start was 9.4 points (95% CI 8.3-10.5), which showed a significant decrease of 6.0 points (95% CI 4.8-7.1) after start of sedation for the total sedation period. In the multivariable analysis, no significant factors influencing baseline discomfort levels were identified. The discomfort and depth of sedation scores were found to be positively correlated, with an r of 0.72 (95% CI 0.61-0.82). The internal consistency of the discomfort scale was good (0.83), but the "Noisy breathing" item was less informative of the total discomfort score.
conclusionsThe efficacy of palliative sedation can be evaluated by measuring discomfort levels combined with sedation/agitation levels. The measurement of discomfort levels might provide a more specific and detailed evaluation of adequate sedation.
