2 PAEDS IN A POD Episode 84 | The Febrile Infant Lottery Released: 24/5/2026 | Runtime: ~20 minutes━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━ EPISODE SUMMARY ━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━This episode opens with a large London study showing that the care a febrile young infant receives depends heavily on which hospital they attend, with full adherence to national guidance achieved in only one in five presentations and over-investigation almost as common as under-investigation. The second main story examines a French randomised controlled trial of automated closed-loop oxygen titration in bronchiolitis — negative on its primary endpoint of length of stay, but with coherent secondary signals on saturation targeting and oxygen flow that make it a useful lesson in reading past the abstract. What's Caught My Eye covers a systematic review of electronic sepsis alerts in children, a multicentre cohort of in-hospital neonatal head injury on the postnatal ward, and a study asking whether comprehensive respiratory virus panels change outcomes in discharged children.━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━MAIN STORY 1: How much does the febrile infant's hospital matter? ━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━The febrile infant under ninety days is one of the highest-stakes presentations in paediatric emergency and acute care. National guidance exists precisely to compress that diagnostic uncertainty into something consistent. This retrospective study across twenty-one London hospitals, run through the London REACH network, tested whether care actually looks the same once that guidance is applied — and the answer is that it does not.Key findings:2,008 presentations of infants aged 90 days or younger; 41.1% were febrile at the point of assessmentBlood tests performed in 73.7% overall, but ranging from 55.4% to 96.7% across sites; lumbar puncture 40.8% overall, range 17.1% to 70.7%; urinalysis 63.4% overall, range 43.4% to 85.4%Antibiotics started in 57.7% overall (site range 35.4% to 90.2%); admission in 63.5% overall (site range 46.7% to 99.2%)Full adherence to national clinical practice guidelines in only 21.9% of presentations; partial adherence 24.4%; non-adherence 31.2%; over-adherence 23.5%Adherence was higher in infants under 28 days and in those febrile during assessmentThe clinical message is that variation runs hard in both directions. We tend to fear under-investigation and the missed serious bacterial infection, but over-investigation — unnecessary lumbar puncture, septic screen, intravenous antibiotics and admission in a well baby — was almost as common, and it is not a neutral act. The practical focus for departments is the infant who is afebrile by the time they are assessed, where the guidance gives least direction and the variation is widest.This is London-specific, retrospective, and the study period overlaps the later pandemic, so the absolute numbers will not transfer directly to a district general setting.Habermann S, Hartzenberg R, Loucaides EM, et al.

This trial tested whether handing the titration to a closed-loop device improves the outcome that matters to families and to flow — length of hospital stay.Key findings:Multicentre randomised controlled trial, ten paediatric departments in France, 2018 to 2023; 103 infants aged 1 to 12 months with acute bronchiolitis requiring oxygen, severe bronchiolitis excludedPrimary endpoint negative: median stay 71.0 hours with the FreeO2 device versus 69.6 hours with manual titration (p=0.39)Time within the target oxygen saturation zone 89.4% with automation versus 74.9% with manual titration (p<0.05)Median oxygen flow 0.1 L/min with automation versus 0.3 L/min manual (p<0.05); no significant difference in re-hospitalisation at 7 or 30 days or in non-invasive ventilation useThe bottom line is that automated titration does not shorten length of stay, so it should not be argued for on that basis, but the secondary signals are coherent — better time in target range at lower oxygen flows. The wider teaching point is that a negative primary endpoint in an underpowered trial is ...
