Scaling up improvement: the drive to reduce healthcare-associated infections in public Brazilian intensive care units across all patient ages.
Article in Infection control and hospital epidemiology, 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
backgroundDespite the availability of straightforward and economic interventions to prevent HAIs, these unintentional adverse events still pose a significant challenge to public health globally. We aimed to evaluate the outcomes of a nationwide project designed to mitigate HAI incidence in intensive care units (ICUs) using the Model of Improvement framework.
methodsA Quality Improvement (QI) study assessing the outcomes of a two-year initiative in Brazilian ICUs from September 2021. A customized Collaborative methodology was applied to mentor and enhance the capabilities of healthcare workers, equipping them with evidence-based, structured, systematic, and auditable QI strategies (prevention bundles) to improve patient care outcomes. A one-year preintervention baseline incidence was established for the three critical HAIs: central line-associated bloodstream infections (CLABSI), ventilator-associated pneumonia (VAP), and catheter-associated urinary tract infections (CAUTI), to compare with the intervention period.
resultsThe initiative encompassed 188 ICUs (169 adults, 11 pediatric, and eight neonatal), recording substantial reductions in HAI incidence density: by 43% for CLABSI (from 5.5 to 3.2 per 1,000 catheter-day), by 51% for VAP (from 13.6 to 6.7 per 1,000 ventilator-day), and by 55% for CAUTI (from 3.2 to 1.4 per 1,000 catheter-day), irrespective of age. Implementing this QI strategy prevented an estimated 7,342 infections.
conclusionOur initiative has been demonstrated to be a feasible and valuable strategy for preventing HAIs in critical care settings. The success of this approach emphasizes the potential for its broader application and reinforces the need for systematic, evidence-based interventions in healthcare settings.
