Signal detection for pediatric patient deterioration with nursing students: An explanatory sequential design mixed-methods study.
Article in International journal of nursing studies advances, 2025. 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
Objective: Failure to rescue occurs when nurses fail to detect signals of clinically significant changes in the early stages of disease complication or patient deterioration. Pediatric patient deterioration detection poses a different challenge because pediatric patients physiologically respond differently from adults. Nursing students are especially challenged in detecting pediatric patient deterioration because adult illness is the primary focus of nursing education. The study aims to identify vital signs that nursing students categorize as signals of pediatric deterioration, determine influences on their response to signals, and how these influences affect their performance in signal detection trials. Methods: To assess and understand nursing students' pediatric deterioration detection performance, an explanatory sequential mixed-method design was conducted with second-semester senior baccalaureate nursing students. Students participated in signal detection trials, and then a subset was interviewed about their performance and thought processing. The quantitative data were analyzed for descriptive statistics, mean rate, sensitivity, and response bias. The qualitative data were analyzed with thematic analysis. The quantitative and qualitative results were compared to examine how performance and influences on response are related. Results: Participants (n=21) had a low sensitivity Conclusion: Students demonstrated low sensitivity in detecting early signs of patient deterioration. These findings highlight the need to enhance student knowledge and preparedness to detect signals of pediatric deterioration early and reduce failure to rescue. This study demonstrates the innovative use of signal detection to assess nursing students' ability to recognize patient deterioration cues. By quantifying the sensitivity index and response bias, educators can identify knowledge gaps and tailor remediation to individual needs. Signal detection testing provides a unique framework to evaluate decision-making under uncertainty, advancing nursing education to better prepare students for clinical practice.
