Episode 88 | The RSV Jab Proves Itself
Released: 19th July 2026 | Runtime: ~20 minutes
━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━
EPISODE SUMMARY
This episode leads with the first national effectiveness data on the UK's maternal RSV vaccination programme — a thirty-seven-hospital study finding that vaccination in pregnancy cut RSV hospital admissions by 61% to six months of age and 76% to three months, while also revealing that a third of mothers still aren't taking it up. The second main story asks whether the paediatric asthma scores now appearing in UK pathways can actually predict who needs admitting after a bronchodilator burst; across ten scores and over twelve hundred children, none reached the accuracy needed to be used that way. What's Caught My Eye covers the near-zero yield of retinal examinations in suspected abuse when head imaging is clear, a study showing that CT use in low-risk head injury is predicted by the clinician rather than the child, and data showing that one in ten children with a CNS infection had been seen and discharged in the preceding week.
━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━
MAIN STORY 1: Does the maternal RSV vaccine work in the real world?
━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━
The UK began offering bivalent RSVpreF vaccination to all pregnant people from 28 weeks in late summer 2024, moving to year-round delivery after an initial catch-up phase; nirsevimab replaced palivizumab for high-risk infants in late summer 2025. Trial efficacy is one thing — this is the first look at what the programme delivers once uptake, timing and ordinary life are in the mix. Note that Episode 85 covered a French cohort comparing nirsevimab against maternal vaccination head-to-head; this is a different question, asked of our own population.
Key findings:
Prospective, test-negative case-control study across 37 BronchStop hospital sites in the UK; parents contributed to protocol design.
1,356 infants aged ≤6 months admitted with acute lower respiratory tract infection were screened; 694 entered the primary analysis (429 RSV-positive, 265 RSV-negative).
Median age at admission 2.2 months for RSV-positive infants, 1.7 months for RSV-negative infants; 57% male.
38% of mothers of RSV-positive infants had received RSVpreF before delivery, against 66% of mothers of RSV-negative infants.
Adjusted vaccine effectiveness against hospital admission: 61% (95% CI 38–75) to age 6 months, and 76% (95% CI 54–87) to age 3 months.
Overall effectiveness of the UK RSV prevention programme: 61% (95% CI 39–75) through to 6 months.

The effect is largest exactly where the disease is most dangerous — the first three months of life. Equally important is the control group: with two-thirds uptake among mothers of RSV-negative infants, this is a story about a vaccine that works and a programme that hasn't yet reached everyone, and those are separate problems.
The design is observational, covers a single season, and deliberately excluded infants born before 28 weeks and those who received nirsevimab, so it measures the maternal vaccine in the population it was designed for rather than at the margins.

━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━
MAIN STORY 2: Can an asthma score tell you who needs admitting?
━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━
Deciding whether a wheezy child goes home or upstairs after the first bronchodilator burst is one of the commonest judgements in paediatric emergency medicine, and structured asthma scores have been quietly appearing in UK departmental pathways as objective disposition aids. The CASPER study, from the PREDICT network, tested whether ten of the most widely used scores are actually good enough for that job.
Key findings:
Multicentre prospective observational study across four Australian emergency departments; 1,238 children aged 2–18 who received at least one bronchodilator dose. Median age 3 years (IQR 2–6); 64% male; 41.4% met admission criteria.
Trained research nurses took observations before and after initial treatment to calculate ten scores: PRAM, SiCAS, CAS, AAIRS, MPIS, PIS, PAS, PASS, Woods and Downs, and the Pulmonary Score.
No score reached the prespecified AUC ROC of ≥0.80 for discriminating admission from discharge. The four best performers (MPIS, SiCAS, PIS, PAS) scored between 0.70 and 0.73.
No score achieved a Youden index of ≥50%, meaning none struck an adequate balance between sensitivity and specificity.
Every one of the ten scores did show that each one-point increase was associated with higher odds of admission (p<0.001).

The clinical bottom line is that these scores measure severity but do not make the disposition decision. They are reasonable for tracking a child over time, structuring a handover or triggering senior review; they are not a threshold to discharge on.
This is Australian data with different admission thresholds to ours, and the median age of 3 means a substantial proportion of the cohort is preschool wheeze rather than established asthma. If your department has a score embedded as a disposition rule, this is a reason to review it against current joint BTS/NICE/SIGN guidance.

1. The retinal examination you probably don't need
A multicentre retrospective study of 2,591 US children under two undergoing child protection evaluation with no intracranial injury on neuroimaging. Retinal examinations were performed in just 10.5% (272 children), and of those only four (1.5%) had retinal haemorrhages — all with a plausible alternative explanation. Worth your time because it makes a reasonable case that the examination can be safely deferred when head imaging is clear, sparing the infant, the family and your ophthalmology colleague, with the authors carving out suspected strangulation and signs of ocular trauma as the exceptions.

2. Why we scan the head injuries the rule says not to
A prospective multicentre study that surveyed 421 emergency clinicians on their experience and risk tolerance, then linked each to the 8,957 PECARN-negative children they had enrolled. 7.3% of these very-low-risk children were scanned anyway, and the predictors were clinician-level rather than patient-level: more years in practice (aOR 1.02), caring for fewer children in one's own practice (aOR 1.55), and self-reported avoidance of uncertain outcomes (aOR 1.31). Worth your time because it is a rare, honest look at the fact that we override a rule we know and trust for reasons that sit in us rather than in the child.

3. The meningitis that went home
A cross-sectional study across five US states of 2,686 children admitted with meningitis, encephalitis or craniospinal abscess, asking how many had a prior emergency department visit within seven days. 10.6% did, at a median interval of two days; in children over 90 days, more than three-quarters of those visits were coded as isolated flu-like symptoms and only 6% had red flags such as altered mental status or neck pain. Worth your time for two numbers: in bacterial cases, a missed visit carried 2.49-fold adjusted odds of neurological complications, and the risk of a missed diagnosis was 3.7 times higher at the lowest paediatric-volume emergency departments — the closest analogue we have to the DGH and the urgent treatment centre.

KEY TAKEAWAYS
━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━
The UK maternal RSV vaccine cut hospital admission with RSV by 61% to six months of age and 76% to three months — British data from 37 hospitals, usable in a conversation with a parent.
Uptake, not efficacy, is now the limiting factor: a third of mothers in the control group had not been vaccinated.
No paediatric asthma score reached an AUC of 0.80 for predicting admission. Use them to measure severity and structure handover, not to decide disposition.
If head imaging shows no intracranial injury, the yield of a retinal examination in suspected physical abuse is around 1.5%, and every positive in this cohort had another explanation.
CT use in PECARN-negative head injury is driven by...

Episode 87 | Second Thoughts on Sugar Gel
Released: 5th July 2026 | Runtime: ~20 minutes
━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━
EPISODE SUMMARY
This episode opens with the school-age follow-up of the hPOD trial, which found that a single prophylactic dose of dextrose gel given to at-risk newborns made no difference to neurocognitive function at six to seven years and was linked to slightly more emotional and behavioural difficulty — a finding that argues against giving gel as routine prevention, while leaving its role in treating established hypoglycaemia intact. The second main story is a UK multicentre cohort asking whether every child with Staphylococcus aureus bacteraemia needs an echocardiogram, and making the case for risk-stratifying instead. What's Caught My Eye covers decision rules to reduce X-rays in children's limb injuries, a prehospital oral sedation pathway for people with learning disabilities, and a study showing how often clinicians mark the wrong spot for a chest drain.
━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━
MAIN STORY 1: Does prophylactic dextrose gel protect the newborn brain?
━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━
Buccal dextrose gel is established for treating neonatal hypoglycaemia. This is the six-to-seven-year follow-up of the hPOD trial, which tested a different question: whether giving gel prophylactically, before the sugar drops, protects long-term neurodevelopment in at-risk babies.
Key findings:
Double-blind, placebo-controlled RCT across nine New Zealand hospitals; a single 0.2 g/kg dose of 40% dextrose gel or placebo at one hour of age.
Just over 1,000 children assessed at 6–7 years, mostly in their own schools.
No difference in the primary outcome of neurocognitive impairment: 59% (gel) vs 57% (placebo), adjusted difference 3% (95% CI −3% to 9%), not significant.
The high baseline rate reflects a broad definition (below −1 SD on any 1 of 7 tests), not that most children were impaired.
On exploratory outcomes, the gel group had more emotional-behavioural difficulty (24% vs 18%) and low psychosocial function (17% vs 12%).

The evidence does not support giving dextrose gel prophylactically to prevent hypoglycaemia in at-risk newborns. It does not change the use of gel to treat an established low glucose alongside a feed, which remains reasonable.
Caveat: the behavioural signals are exploratory secondary outcomes and should be read with caution given multiple comparisons.

━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━
MAIN STORY 2: Does every child with Staph aureus bacteraemia need an echo?
━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━
In adults, Staph aureus in the blood triggers a near-automatic search for infective endocarditis. This UK cohort asks whether children, in whom endocarditis is rare without risk factors, need the same universal approach.
Key findings:
Retrospective cohort, six North West London hospitals, 2018–2023, 101 children with Staph aureus bacteraemia; 70% had transthoracic echo, 30% did not.
Endocarditis confirmed in 4 children (5.6% of those scanned), all right-sided, and all with an established risk factor (congenital heart disease, central venous catheter, or intravenous drug use).
No endocarditis in any child with a structurally normal heart and no risk factor.
Features associated with endocarditis: embolic phenomena, persistent bacteraemia beyond 72 hours, and polymicrobial growth.

A risk-stratified approach looks defensible: echo can reasonably be omitted in a child with a structurally normal heart, no risk factor and no clinical or microbiological clue, and reserved for those with a heart lesion, an indwelling line, a relevant history, a murmur, embolic signs, or persistent or polymicrobial bacteraemia.
Caveat: retrospective, single-region, small numbers, and the longer stay in the echo group is confounded by indication; prospective validation is needed before changing protocol.

WHAT'S CAUGHT MY EYE

1. Decision rules to cut X-rays in children's limb injuries
A systematic review and meta-analysis of eight studies and nearly 8,000 children found that ankle decision rules substantially reduce radiography (odds ratio around 0.11), while a wrist rule missed eight fractures and a nurse-applied rule in one trial increased imaging and missed sixteen injuries. Worth your time because it shows imaging reduction is achievable but depends heavily on which rule, which joint, and who applies it.

2. Prehospital oral sedation for people with learning disabilities
The Barts Health Physician Response Unit built a pathway giving carer-administered oral ketamine and midazolam to let people with learning disabilities tolerate procedures that would otherwise be impossible; in the first year, nine of thirty-six referred patients were sedated with no serious adverse events and every patient tolerated their procedure. Worth your time as a practical model of reasonable adjustments that avoids restraint and parenteral routes.

3. How often do we find the wrong spot for a chest drain?
When fifteen paediatric emergency physicians marked the fifth intercostal space by landmarks and were checked with ultrasound, only 37% of 240 marks were accurate, nearly one in ten sat below the diaphragm, and more experienced clinicians were more likely to mark too low. Worth your time as a strong argument for an ultrasound check before this rare, high-stakes procedure.

━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━
KEY TAKEAWAYS
━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━
Prophylactic dextrose gel does not improve neurocognition at 6–7 years in at-risk newborns and may carry a small behavioural cost.
Gel remains reasonable for treating an established low glucose alongside a feed — prophylaxis and treatment are separate questions.
Not every child with Staph aureus bacteraemia needs an echo; risk-stratify by heart structure, risk factors, and clinical or microbiological features.
Ankle decision rules reliably reduce limb X-rays, but the choice of rule and who applies it determines whether that is safe.
Landmark placement of chest drains is frequently inaccurate and experience does not protect against it — check with ultrasound.

EPISODE SUMMARY
This episode leads on a problem every acute paediatric unit now lives with: the child in mental health crisis admitted to a general children's ward while waiting for specialist care. A new UK consensus study sets out sixteen practical, risk-stratified strategies that a non-specialist team can use to keep these young people safer. The second story turns to the forearm fracture, with a large cohort showing that one child in eight returns to the emergency department within a week of casting — rising to one in four for reduced distal both-bone fractures — and a companion piece asking whether ultrasound can guide the reduction itself. What's Caught My Eye covers whether "highly toxic" drugs really threaten toddlers after a single dose, real-world evidence that earlier egg introduction cut egg allergy, and the refreshed top ten research priorities for paediatric emergency medicine across the UK and Ireland.
━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━
MAIN STORY 1: Keeping children in mental health crisis safe on the ward
━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━
Children and young people in mental health crisis are routinely admitted to acute paediatric wards that were never designed to hold them, cared for by staff with little mental health training. This UK mixed-methods study asked a deliberately practical question: while these young people are in our care, what can a general team actually do to reduce risk?
Key findings:
Twenty-six candidate risk-mitigation strategies were generated from a systematic review and qualitative interviews.
Sixteen reached expert consensus (≥70% agreement) for clinical usefulness among a panel of 16 healthcare professionals and experts by experience.
Prioritised strategies included structured safety checks on admission and daily thereafter, proactive environmental modification to remove triggers and ligature risks, one-to-one observation reframed around therapeutic engagement rather than surveillance, timely escalation to specialist mental health services, and routine multidisciplinary safety huddles.
Each strategy was mapped to clinical risk level (low, medium, high, very high) using a validated paediatric mental health risk assessment framework.

For practice, this converts a familiar sense of helplessness into a structured, risk-matched checklist that any acute paediatric team in the NHS can adopt immediately, without waiting for system-level reform.
The caveat: these are consensus-derived strategies from a small expert panel, not outcomes from a trial, so this is a framework for good practice rather than proof of reduced harm — and escalation to specialist services remains part of it, not an alternative to it.

━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━
MAIN STORY 2: Forearm fractures — life after the cast, and guiding the reduction
━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━
The forearm fracture is everyday work in paediatric emergency medicine, but we rarely track what happens once the child leaves with a cast. This single-centre cohort quantified unplanned return visits within the first week, and a companion Archives piece asks whether point-of-care ultrasound could improve the reduction at the bedside.
Key findings:
Among 551 children treated with circumferential casting (from 4,661 forearm fractures reviewed), 67 (12.2%) made an unplanned return to the ED within seven days.
92.5% of returns were for pain and around 95% required cast modification.
Return rates varied sharply by pattern: distal radius and ulna 23.8%, midshaft both-bone 15.7%, distal radius alone 8.5%, other 5.5%.
Returns were more than three times as likely after reduction than after in-situ casting (16.1% vs 4.3%), peaking at 27.1% for reduced distal both-bone fractures.
There were no cases of compartment syndrome and 98.4% completed non-operative treatment successfully.

The clinical bottom line is about specific, risk-matched safety-netting: a reduced distal both-bone fracture carries a one-in-four chance of a painful early return, so families with high-risk patterns need tailored expectations and follow-up rather than a generic discharge.
This is single-centre data from outside the UK, so absolute rates will differ here, but the pattern — reduced wrist fractures being the ones that bounce back — will be familiar to any UK ED or fracture clinic, and the ultrasound question speaks to whether a better first-time reduction could cut returns at source.

1. Does one pill really kill?
A prospective registry across 58 Spanish emergency departments examined accidental ingestions of "highly toxic" drugs — the agents reputed to kill a toddler in a single dose — in children under eight. Of 61 such ingestions, most often cardiovascular drugs and opioids, only four children (under 7%) were symptomatic, none needed advanced airway or circulatory support, and there were no deaths. It is a measured argument for evidence-based risk stratification over blanket alarm, though the number of genuinely toxic cases is small.

2. Did earlier egg introduction actually cut egg allergy?
Two population-based cohorts of twelve-month-olds in Melbourne, before and after guidelines changed to recommend earlier egg introduction, had egg allergy confirmed by skin prick test and oral food challenge. As the typical age of introduction fell from eight to six months, confirmed egg allergy dropped from 9.2% to 7.6% overall, and from 34.6% to 21.9% in the highest-risk infants with early eczema. It is real-world, population-level evidence that a weaning guideline change moved the dial — albeit an Australian before-and-after comparison rather than a trial.

A James Lind Alliance priority-setting partnership rebuilt the research agenda for paediatric emergency medicine across the UK and Ireland, a decade on from the original and this time with patients and carers alongside clinicians.

These questions will shape what gets funded and studied in the specialty for the next decade, and the work comes from the PERUKI network.

━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━
KEY TAKEAWAYS
━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━
A general paediatric team is not powerless with a child in mental health crisis: daily structured safety checks, removing risks from the environment, and engagement-focused one-to-one care are all within reach, and there is now a consensus framework to organise them by risk level.
These are consensus strategies, not trial outcomes — use them as a structure for good practice, not as proof of reduced harm.
Most early returns after a forearm cast are pain and cast problems, not emergencies, but reduced distal both-bone fractures return roughly one time in four and warrant specific safety-netting.
In a large Spanish registry, accidental ingestions of even "highly toxic" drugs rarely caused symptoms and caused no deaths — grounds for sharper risk stratification.
Earlier egg introduction was followed by a measurable population fall in egg allergy, most markedly in infants with early eczema.

2 PAEDS IN A POD Episode 85 | The Trouble With Boluses
Released: 07/06/2026 | Runtime: ~20 minutes
EPISODE SUMMARY
This episode leads on fluid in childhood sepsis. A new multicentre cohort from Australia and New Zealand found that mortality rose with the volume of bolus fluid given in the first day, but not with the total volume of fluid — a finding set alongside the recently published PRoMPT BOLUS trial, which showed that balanced fluid and saline produce the same kidney outcomes. The second story returns to the febrile infant for a third time, with a meta-analysis quantifying the risk of serious bacterial infection in the well sixty-to-ninety-day-old. What's Caught My Eye covers the TWIST score and ultrasound for the acute scrotum, nirsevimab versus the maternal RSV vaccine head to head, and language barriers and safety in the paediatric emergency department.
━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━
MAIN STORY 1: How much fluid is too much in childhood sepsis? ━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━
Fluid is the first thing we reach for in the septic child, and the volume question has never been fully settled. This cohort measured the fluid children actually received in the first twenty-four hours and asked how it related to outcome, arriving just as PRoMPT BOLUS reported on the separate question of which fluid to use.
Key findings:
5,352 children with suspected community-acquired sepsis across 11 emergency departments in Australia and New Zealand (2021–2023); median age 2.6 years.
In-hospital mortality was low at 1.1%; around 5.5% met Phoenix sepsis criteria.
Median total fluid in the first 24 hours was 40 mL/kg, of which the bolus component was 10 mL/kg.
Mortality rose with increasing bolus volume but not with increasing total fluid; the unadjusted odds ratio for death with more than 55 mL/kg versus less than 15 mL/kg of bolus fluid was 20.5 (95% CI 8.0–52.5).
For context, PRoMPT BOLUS (9,041 children, 47 departments, five countries) found no difference in major adverse kidney events between balanced fluid and 0.9% saline (3.4% vs 3.0%), with less hyperchloraemia in the balanced-fluid group.

For practice, the converging message is that the fluid you choose matters less than hoped, while the volume you give may matter more than thought. This supports the titrated, reassess-after-each-bolus approach that NICE and APLS already ask for, rather than a fixed escalator.
Important caveat: the bolus–mortality association is unadjusted and observational, and the sickest children in refractory shock receive the most bolus fluid, so this does not show that boluses cause harm and is not a reason to withhold fluid from a shocked child.

━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━
MAIN STORY 2: How risky is the febrile two-month-old? ━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━
The sixty-to-ninety-day-old is the febrile infant our guidelines treat least consistently — some pathways stop at sixty days, others lump the whole under-ninety group together. This meta-analysis supplies the missing denominator for that group, completing a run that has moved from risk stratification, through practice variation, to underlying prevalence.
Key findings:
59 studies, 20 distinct datasets, just under 34,835 well-appearing, previously healthy febrile infants aged 60–90 days.
Pooled prevalence of invasive bacterial infection was 1.11% (95% CI 0.84–1.47), roughly 1 in 90.
Almost all of that was bacteraemia at 1.01%; bacterial meningitis was rare at 0.11%, roughly 1 in 900.
Estimates held across every sensitivity analysis, including removal of the single largest study.

The clinical bottom line is a number to carry into both your own reasoning and the conversation with parents: in the well infant in this band, meningitis risk of around one in nine hundred is a reasonable thing to weigh when deciding whether this particular baby needs a lumbar puncture or a more measured pathway with good safety-netting.
These are international data, so map the figures onto your local febrile infant pathway and the NICE traffic-light thresholds rather than applying them in isolation.

WHAT'S CAUGHT MY EYE ━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━
1. TWIST and ultrasound for the acute scrotum
A retrospective study of just over 500 boys aged fifteen and under with an acute scrotum tested how the TWIST score and point-of-care ultrasound perform in the hands of emergency physicians and paediatricians. The TWIST score had a sensitivity of around 91% and a negative predictive value of 99%, and adding ultrasound pushed sensitivity to 96% and negative predictive value to 100%. Worth your time because it supports front-door risk stratification of the acute scrotum, though the residual false negatives mean it cannot be used to rule torsion out.

2. Nirsevimab versus the maternal RSV vaccine, head to head
A French national cohort of more than 164,000 infants across the 2024–25 season compared nirsevimab given at birth against maternal RSVpreF vaccination. Nirsevimab was associated with about a 22% lower chance of RSV-related hospitalisation (OR 0.78, 95% CI 0.70–0.86), but that advantage disappeared when the maternal vaccine had been given at least eight weeks before delivery. Worth your time because both products are now live in the UK, so this speaks directly to counselling families and to the timing of maternal vaccination.

3. Language barriers and safety in the paediatric emergency department
A scoping review of 33 studies mapped where, along the emergency care journey, language barriers threaten the safety of children's care. Risk appeared at every stage, but discharge — the moment we hand over safety-netting and home-care advice — was flagged most often. Worth your time as a pointed reminder that, in a multilingual NHS population, the discharge conversation is a safety-critical step rather than an afterthought.

KEY TAKEAWAYS ━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━
PRoMPT BOLUS shows balanced fluid and saline produce the same kidney outcomes in paediatric septic shock; the choice of fluid matters less than once hoped.
New observational data suggest it is bolus volume, not total fluid, that tracks with mortality — a reason to give a measured bolus, reassess, and only repeat if the child still needs it, not a reason to withhold fluid.
In the well sixty-to-ninety-day-old, invasive bacterial infection runs at about 1 in 90 and meningitis at about 1 in 900 — a denominator for proportionate investigation and honest parent conversations.
The TWIST score and ultrasound can risk-stratify the acute scrotum at the front door but cannot rule torsion out.
In a multilingual population, discharge and safety-netting are the highest-risk points for language-related harm.

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 assessment
Blood 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 assessment

The 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.

MAIN STORY 2: Automated oxygen titration in bronchiolitis ━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━
Oxygen titration in bronchiolitis is a constant low-level drain on nursing time across the winter. 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 excluded
Primary 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 use

The 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 not the same as nothing having happened; length of stay in bronchiolitis is driven by feeding and overall trajectory far more than by oxygen delivery precision, so it may always have been an insensitive endpoint for this intervention.
This sits within the larger UK conversation on permissive hypoxaemia and oxygen saturation targets in bronchiolitis, and is worth reading alongside the BIDS trial and current oxygen-target guidance rather than in isolation.

WHAT'S CAUGHT MY EYE ━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━
1. Do electronic sepsis alerts actually save children?
A systematic review and narrative synthesis of twelve studies of EMR-embedded automated sepsis alerts in children under eighteen. Alerts improved process measures — faster time to antibiotics in four of six studies and faster fluids in two of five — without increasing hospital admissions or overall antibiotic use, but a mortality benefit was shown in only one study, in a PICU population. As more NHS trusts switch on electronic sepsis triggers, this is the honest evidence position to know: the process metrics move, the hard outcome data do not yet exist.

2. The neonatal head injury that happens on your postnatal ward
A retrospective cohort across fifteen Italian maternity units of newborns who fell during routine postnatal stay, with the PECARN rule applied retrospectively. Thirty-nine newborns, median age at injury 32 hours, most falls at night in rooming-in; a quarter (25.6%) had a clinically important traumatic brain injury but none needed neurosurgery or had sequelae, while 88.9% of low-risk babies were imaged anyway. A low-severity, high-anxiety event most clinicians never see described, sitting right at the edge of where PECARN was never validated — the newborn.

3. Does a bigger respiratory virus panel change anything?
A retrospective cohort of 2,346 children discharged from a paediatric emergency department with a viral respiratory illness, comparing a limited three-pathogen panel against a comprehensive twenty-two-pathogen panel. No difference in seven-day return visit rate after adjustment (aOR 0.96, 95% CI 0.67–1.38) and no difference in interventions or disposition on return. For the well child being discharged with an obvious viral illness, the bigger panel did not change outcomes — a clean stewardship argument for testing less, not more.

KEY TAKEAWAYS
━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━
Febrile infant care varies widely between hospitals, with full guideline adherence in only one in five presentations
Over-investigation of the well febrile infant is almost as common as under-investigation, and is not a harmless default; the afebrile-on-assessment infant is where guidance is weakest
Automated oxygen titration in bronchiolitis did not reduce length of stay, but a negative primary endpoint in an underpowered trial warrants reading the secondary data
Electronic sepsis alerts reliably speed up antibiotics and fluids but the mortality evidence is not yet established
For the well child discharged with a viral respiratory illness, a comprehensive virus panel did not improve outcomes over a limited one
