Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
Topical coconut oil is the intervention

Eligible infants in neonatal units randomised to the study intervention will receive topical coconut oil starting within 24h from birth. Preterm infants’ skin condition deteriorates rapidly in the first days of life therefore commencement of the intervention within 24h of birth is essential.
• Infants <25 w GA will receive 5ml of coconut oil 4x/day for the first week of life, then 5ml 2x/day until transferred to an open cot.
• Infants >25 w GA will receive 5ml 2x/day until transferred to an open cot.
• Once cared for in an open cot, infants will receive topical coconut oil 1x/day until discharge from the tertiary neonatal unit (to minimise undressing and handling of the infant).
Application:
- Use a new sachet for each application.
- The parents should apply the coconut oil to their infant’s skin if they wish, under supervision of the bedside nurse.
- Apply topical coconut oil during routine care to the entire skin (front and back). Do not apply coconut oil to the face, scalp, and sites of vascular access or other devices (e.g. chest drain).
- Use only a few gentle strokes to apply coconut oil. Do not massage. Application should only take 1-2 minutes per side.
- Discard any unused oil in a sachet after opening.

Monitoring
Pharmacy stock reports at intervention sites will be compared to the number of eligible infants and expected number of days of treatment will provide an indication of compliance with coconut oil use.
Further, monitoring of 20% of eligible infants’ medication charts at the intervention sites, where coconut oil will be prescribed and application signed-off, will be conducted to ensure compliance with the study intervention.

Allocation to intervention
Randomised controlled trial
Procedure for enrolling a subject and allocating the treatment (allocation concealment procedures)
The allocation of the study invention will not be concealed. Participating sites will be cluster randomised into intervention and control sites, stratified by cluster size and incidence of late-onset sepsis. Participating sites will be advised of their allocation to the intervention or control arm of the study. At intervention sites all eligible infants receive coconut oil for skin care. In sites randomised to the control arm of the study, all eligible infants will continue with routine skin care.
Methods used to generate the sequence in which subjects will be randomised (sequence generation)
Participating sites will be cluster randomised by computer generated program, stratified by size of site and incidence of late-onset sepsit

Efficacy
Statistical methods / analysis
The current incidence of LOS in extremely preterm infants is ~25% . We will recruit 1232 infants <28w GA from 18 sites with average 80 neonates per centre, yielding >80% power to detect a 35% reduction of LOS incidence from 25% to 16.25%, with two-tailed alpha of 0.05 and intraclass correlation (ICC) of 0.008 (PASS 2019 Power Analysis and Sample Size Software (2019). NCSS, LLC. Kaysville, Utah, USA). These calculations also allow for a reduction in incidence of LOS due to anticipated future advances in care, 5% loss to follow-up and 5% non-compliance
