1 · What the graph read from it

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.

2 · The registry

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

introductionWe aim to evaluate the implementation of the modified Step-by-Step algorithm on rates of administration of empirical intravenous antibiotics and lumbar punctures performed among young infants at risk of serious bacterial infections (SBIs). METHODOLOGY: A retrospective cohort study enrolled febrile infants aged ≤90 days old between December 2017 and June 2023 in KK Women's and Children's Hospital (KKH). The modified Step-by-Step algorithm was implemented as part of a quality improvement (QI) project. SBIs were defined as urinary tract infections, bacteraemia or bacterial meningitis. Propensity score matching was performed, and the rates of empirical antibiotic use and lumbar punctures were compared before and after QI.

resultsOf the 3475 infants, 684 pairs (pre-QI and post-QI) were compared following propensity matching. The median age was 34 (IQR, 11-60) days pre-QI and 37 (IQR, 13-65) days post-QI (p=0.334). 175/684 (25.6%) infants pre-QI and 169/684 (24.7%) post-QI had SBIs (p=0.755). Overall, empirical antibiotic use reduced by 11.4% (513/684 (75.0%) to 435/684 (63.6%), p<0.001) and lumbar punctures performed reduced by 8.8% (378/684 (55.3%) to 318/684 (46.5%), p=0.001). Among infants without SBIs, empirical antibiotic use reduced by 13.6% (339/509 (66.6%) to 273/515 (53.0%), p<0.001) and lumbar punctures performed reduced by 11.0% (245/509 (48.1%) to 191/515 (37.1%), p<0.001).

conclusionWe report a safe and effective reduction in exposure to empirical antibiotics and lumbar punctures performed on febrile young infants following the introduction of the modified Step-by-Step algorithm.
