Targeting discrepancies in linear growth measurements in the neonatal intensive care unit through nursing interventions: a quality improvement initiative.
Article in Journal of perinatology : official journal of the California Perinatal Association, 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
objectiveAccurate length measurements are essential for infants to identify growth deficiencies and adjust nutrition accordingly. The gold standard for length measurement in infants is using a length board with two people to obtain an accurate clinical assessment. We aimed to improve the number of measurements with the desired minimal difference, defined as a discrepancy ≤1 cm between nurse and audit measurements, in our center. Our secondary aim was to increase and maintain the number of length boards available.
methodsThis quality improvement (QI) study used a before-and-after intervention comparison design in a single-level IV neonatal intensive care unit between June 2023 and December 2023, completing two Plan-Do-Study-Act (PDSA) cycles and one sustainability cycle that targeted nursing interventions. Blinded audits were performed by the QI team < 48 h after bedside nurse measurement and discrepancies between measurements were recorded. Chi-squared testing determined the significance between measurement discrepancies at each time point.
resultsThe QI team measured 34 infants at each time point for 136 total measurements. There was a significant improvement in the desired minimal difference between the pre-intervention and post-PDSA #2 groups (38% vs 74%, p = 0.003) and between the pre-intervention and sustainability cycle groups (38% vs 71%, p = 0.007). There was no significant difference between PDSA #2 and our sustainability cycle. There was a 32% improvement among infants with consistent length percentiles between nurse and audit measures after PDSA #2 (42% vs 74%, p = 0.012). The number of length boards was increased during the study. Anonymous nursing surveys revealed an improvement in the perceived ease of use of length boards (51-71%) and minimized knowledge gaps.
conclusionsDuring the time of our intervention, there was an improvement in the precision of linear measurements and length board usage. Future PDSA cycles will focus on increasing the availability of length boards and establishing continued length board education.
