Quality improvement project to reduce intraventricular haemorrhage in very preterm infants failed due to increased life-sustaining intensive care at low gestational age.

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
objectivesIn October 2016, a single centre quality improvement programme 'IBIS' (from the German "Intraventrikuläre Blutungs-Inzidenz Senken"), an intraventricular haemorrhage (IVH) prevention bundle had the Specific Measurable Achievable Reasonable Time-bound (SMART) Aim to reduce IVH incidence from 29.6% to 18.5% within 2 years for very preterm (gestational age (GA) between 23 0/7 and 29 6/7).
designMonocentric retrospective cohort study of a failed quality improvement project using prospectively collected data including 1276 live-born very preterm infants between 2010 and 2023. Primary outcome measures were IVH, severe IVH and death or severe IVH. Statistical analysis included propensity score matching.
interventionsIBIS, an ongoing IVH prevention bundle based on a systematic literature search starting in October 2016.
resultsComparing pre-IBIS patients (2010-September 2016) to IBIS patients (October 2016-2023) revealed no reduction in IVH (25.1% vs 25.1%) or severe IVH (9.6% vs 9.1%). Instead, mortality (24.8% vs 13%) and delivery room mortality (9% vs 5%) were almost halved and fewer infants died after primary palliative care (8.5% vs 4.7%) or after redirection from intensive to palliative care (15.1% vs 7.9%). Longitudinal analysis revealed no trends for IVH or severe IVH over the entire period. Limiting the analysis to the IBIS period reveals a significant trend for fewer IVH (p=0.001). Propensity score matching revealed significant reduction for severe IVH (OR 0.62, 95% CI 0.39 to 0.99) and death or severe IVH (OR 0.42, 95% CI: 0.3 to 0.59) but not for IVH.
conclusionsThe IBIS SMART Aim to reduce IVH failed. Simultaneously, survival was significantly increased by the increased provision of life-sustaining intensive care at lower GAs, which possibly led to an increased risk for acquiring IVH. Our results highlight the need for a better understanding of the effects of extending perinatal interventional activity to lower GAs on adverse outcome monitoring.
