Improving peripheral arterial catheter placement in critically ill children: a pre-post quality improvement study.
Article in Frontiers in pediatrics, 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
Introduction and aims: Peripheral arterial catheter (PAC) assessment and insertion are essential but technically demanding procedures in pediatric intensive care. Practice varies widely, and inconsistent adherence to evidence-based standards contributes to preventable complications. This study aimed to improve the quality and safety of arterial catheterization in critically ill children through a structured quality improvement approach. Methods: A pre-post quality improvement study was conducted in a pediatric intensive care unit (PICU) across three phases: baseline (April-September 2024), implementation (October 2024-February 2025), and follow-up (March-September 2025). Phase-specific samples comprised 121, 76, and 63 patients and 170, 105, and 100 catheterizations, respectively; patients could contribute to more than one phase. A structured audit-and-feedback system measured adherence to 12 operational audit criteria derived from 10 retained evidence-based recommendations. Barriers to best practice were identified through stakeholder interviews, and a multi-component intervention bundle-incorporating standardized checklists, ultrasound-guided cannulation training, electronic decision support, and tiered competency assessment-was developed and implemented. Statistical process control charts were the primary longitudinal analysis, with phase comparisons as supportive analyses. Results: Overall nursing adherence increased from a baseline centerline of 57.0% to a post-implementation centerline of 74.3% (baseline-to-implementation Conclusions: The quality improvement bundle was associated with improved process adherence and lower observed complication rates in pediatric PAC management. However, the uncontrolled design limits causal attribution for the safety outcome. Assessment adherence responded rapidly, whereas insertion performance and first-attempt success remained operator-dependent, supporting continued competency-based training and routine ultrasound guidance.
