Essential Safety Sheet in University Hospital and Healthcare Laboratories: A Comprehensive Evaluation Study with Longitudinal Impact Analysis.

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
BACKGROUND/
objectivesSafety information in hospital laboratories is often fragmented or difficult to retrieve under time pressure. We developed an Essential Safety Sheet (ESS) to present critical, task-level safety information immediately and evaluated its effectiveness on safety performance and incidents.
methodsWe conducted a mixed-methods evaluation across eight university hospital laboratories from March 2023 to August 2024, including a 13-month interrupted time series with a concurrent difference-in-differences comparison between ESS and control laboratories (pre-implementation 6 months, implementation month, post-implementation 6 months). Primary outcomes were (1) emergency escalation accuracy, (2) information search time for task-critical items and (3) laboratory incident rates. Segmented regression models with robust Standard errors estimated level and slope changes; parallel trends were assessed pre-intervention. Multiple comparisons across the three primary outcomes were controlled for using the Bonferroni correction. Qualitative usability feedback was analyzed to contextualize the quantitative effects.
resultsESS implementation was associated with significant improvements in information search time and reductions in incident rates that were sustained over the post-implementation period in the ESS laboratories relative to the controls. Escalation accuracy improved in direction but did not reach statistical significance after multiple comparison correction (Bonferroni-adjusted
conclusionsA concise, task-level safety sheet can enhance the speed of safety-critical information retrieval and contribute to lower incident rates in hospital laboratories. While escalation accuracy showed only a favorable trend after correction, overall results support ESS as low-cost, scalable interventions to strengthen laboratory safety performance. Future studies should test generalizability across more sites and tasks to assess longer-term sustainability.
