Delirium in critically ill children: a retrospective pre- and post-cohort study on the introduction of delirium screening in a paediatric intensive care unit.

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
backgroundPaediatric delirium is a neuropsychiatric disorder with disrupted cerebral functioning due to underlying disease and/or critical care treatment. It has been reported in up to one third of paediatric intensive care admissions, with hypoactive delirium most prevalent in children.
aimThe aim of this study was to assess whether the introduction of delirium screening was associated with a change in the pharmacotherapy exposure and clinical outcomes.
methodA retrospective pre and post cohort study of all admissions > 48 h who required mechanical ventilation between 11th March 2019 and 11th March 2021. Cohort 1 (11th March 2019-11th March 2020) prior to the introduction of delirium screening and cohort 2 (12th March 2020-12th March 2021) after delirium screening. Patients < 3 months old, who were never mechanically ventilated, admitted <48 h, continuously receiving neuromuscular blockade or deeply sedated were not included. A multivariate model was created to compare pharmacotherapy use before and after implementation of delirium screening.
resultsTwo thousand and thirty-four patient encounters were identified with 588 meeting the inclusion criteria (364 cohort 1 and 224 cohort 2). There was a reduction in usage of infusions of morphine (decrease in doses of 18% p < 0.05) and midazolam (50% reduction in patients receiving p < 0.05), after screening commenced. Chloral hydrate use was unchanged however cohort 2 received lower daily doses (p < 0.05). Clonidine infusion use increased for cohort 2 (16% v 28% p < 0.05), with lower daily doses (23 v 13 µg/kg/day p < 0.05). Positive clinical outcomes such as decreased duration of mechanical ventilation, length of stay and out of range sedation and withdrawal scores were also observed.
conclusionIntroduction of a paediatric delirium care bundle including screening tool and associated education was associated with decrease in exposure to modifiable pharmacotherapy risk factors for the development of paediatric delirium. These findings should be further evaluated in future interventional studies.
