The National Institute for Health and Care Excellence (NICE) has updated its neonatal infection guideline to allow some newborns receiving precautionary antibiotics to leave hospital earlier and complete treatment at home with oral antibiotics. 

The recommendations apply to babies born from 35 weeks' gestation who are clinically stable, feeding adequately, and responding as expected to initial intravenous antibiotic therapy.

NICE said the change could reduce hospital stays by up to 2.7 days per baby, based on evidence from the NOAH Project in Devon. The project estimated that up to 12,000 babies a year in England could benefit if the approach is rolled out nationally, freeing neonatal unit beds for babies requiring intensive care and reducing pressure on specialist wards.

Eric Power, interim director of the Centre for Guidelines at NICE, said the update would improve the experience of some mothers during the first few days with their newborn. “This update means families whose babies are well and responding to treatment can settle at home in familiar surroundings, give their baby their medication with confidence, and still have the full support of their neonatal team every step of the way,” he said.

Clinical Criteria for Switching Treatment

Eligible babies must have a negative blood culture but require antibiotics beyond 36 hours because the initial clinical suspicion of infection was strong. Clinicians may consider switching from intravenous to oral antibiotics at 36 hours or later to complete a course of up to 7 days in total, provided the baby’s clinical condition is reassuring, there are no current clinical indicators of ongoing infection, C-reactive protein levels and trends are reassuring, and the baby is tolerating oral feeds. 

NICE recommends amoxicillin as the oral antibiotic, unless local bacterial resistance data indicate that a different antibiotic is needed. The guideline notes that amoxicillin is licensed for neonates but not specifically for early-onset neonatal infection, and that the BNF for Children is reviewing the recommended dosage for neonates.

The decision to switch to oral antibiotics or allow a baby to go home should be agreed by a senior neonatologist or paediatrician, at consultant or similar level.

Risk Assessment for Early-Onset Infection

All newborns are assessed for specific risk factors for early-onset neonatal infection. These include suspected or confirmed infection in another baby in a multiple pregnancy, maternal history of invasive group B streptococcal infection, maternal group B streptococcal colonisation, preterm birth before 37 weeks following spontaneous labour, confirmed membrane rupture exceeding 18 hours before preterm birth or 24 hours before term birth, and suspected maternal sepsis during labour or early postpartum period.

The updated guidance clarifies that, for term births, the key factor is the total time between rupture of membranes and birth. Confirmed rupture of membranes for more than 24 hours before a term birth is now listed as a risk factor, regardless of whether the waters broke before active labour began. 

Evidence and NHS Impact

Three pilot projects across nine NHS sites in England have demonstrated the safety of home-based antibiotic completion. Evidence showed that babies who completed their antibiotic course at home did as well as those who remained in hospital.

Dr Tim Watts, NICE guideline committee member and consultant neonatologist at Evelina London Children’s Hospital, said national rollout would be “an important step forward both for families and the NHS.” He added, “We have seen that babies can complete their antibiotic course just as safely at home as in hospital and that many families prefer settling their new babies in at home.”

Shorter stays could free up neonatal transitional care and postnatal beds for mothers and babies who need hospital-based care, while also reducing exposure to gentamicin and the need for repeat cannulation in babies who can safely switch to oral treatment.

Implementation and Safety

Before discharge, parents or carers must be trained by neonatal teams to administer oral antibiotics, and the first dose should be administered under supervision in hospital. They should also know when and how to seek medical help, have any concerns addressed, and there should be no other reason for the baby to remain in hospital.

Healthcare providers must conduct at least two follow-up consultations after discharge to monitor the baby's progress and ensure treatment effectiveness.

The guidance emphasises that recommendations are not mandatory, and healthcare professionals retain responsibility for making decisions appropriate to individual circumstances in consultation with families and carers.
