Qualitative feedback on what observers had learnt after reviewing the recordings

Category	Feedback
Experience	Observers mentioned ‘a lot of different variations in technique for placing lines’.
Equipment, medication and timing	To think about ‘sedation balance’ and ‘comfort of the baby’, meaning the sequence of sedation, removal of CPAP, mask/t-piece application, ventilation and the ‘use of different catheters (for MIST)’ as well as the necessity to ‘take more time to give MIST’.
Environment and awareness	To change ‘the position of the baby or the monitor for a better visual’ and think about ‘the position of material in the room’. To acknowledge to ‘think about the blade you use’.
Sterility	Observers noticed ‘violations in the sterile technique’. In terms of central line insertion, one observer mentioned that it is important to ‘check sterility, also for those around’ and to think about ‘how to improve sterility and increase awareness about sterility’.
Point-of-view recording	Point-of-view recording was especially ‘worthwhile for learning umbilical catheterization and the crucial steps of the sterile technique’. It helped to see the ‘procedure through the eyes of the neonatologist’ and ‘how others operate’.
Technique	Some observers claimed that the videolaryngoscope blade 1 ‘can be a problem because the light of the blade reflects on the tongue’. It was further mentioned that the videolaryngoscope blade should be placed on the right side of the patient to avoid ‘left-handed insertion of the laryngoscope’.
Education and training	Eye-tracking technology is ‘good to learn’ and ‘very nice to refresh’ educational aspects. To acknowledge the ‘differences in performing the procedure’ brings attention to changes such as ‘start the procedure with the left hand and not with the right hand, otherwise you have to change an extra time’.
Technical issues	In some recordings it was ‘difficult to see the head of the patient’.

CPAP, continuous positive airway pressure; MIST, minimally invasive surfactant therapy.
