Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
Neonatal nurses will assess the weaning criteria. The anticipated time to assess each neonate will be 10 minutes per neonate. Babies will be assessed as able to be weaned when reaching 34 weeks or weight of 1400g (if older).
Prior to weaning neonates' axillary temps will be assessed for 48 hrs and if over or equal to 36.7 degrees C and crib temp average less than or equal to 27 degrees C, the baby can be weaned to a cot.
The babies' temperatures will be closely monitored for 7 days from the point of weaning into a cot.
All details will be recorded onto an excel chart and in the medical records.

Prevention
Comparator / control treatment
The control/historical group is standard/usual care and practice for weaning out of incubators. The practice is currently based on individual the clinician's assessment of the baby's readiness to wean into a cot - no specific age or weight criteria have been identified.

The control/historical group data was collected from a 2 year period spanning from June 2019 to May 2021.
