Plain English Summary

Background and study aims
When babies are born early they might not have developed the coordination needed to suck, swallow and breathe as they feed. Before babies are ready to feed using their mouths (oral feeding), feeds can be given by a tube running from their mouth or nose into their stomach. When the baby is ready this can be changed to feeding through their mouth, by breast, bottle or a cup or spoon. Many babies at this stage are fed at set (scheduled) times while others are fed when they show signs that they are hungry (cue-based). Some research has shown that feeding babies when they show they are hungry might be beneficial for them and their parents. For example, babies may be discharged from hospital earlier. Cue-based feeding may also allow parents to better understand the needs of their baby and become more involved in providing care. We aim to develop a written plan for cue-based feeding that includes training for healthcare professionals and education materials for parents, and to test this plan to see if it works in neonatal units and is acceptable to parents and staff. We will also find out if the plan could be tested in a future study comparing cue-based with scheduled feeding for premature babies in neonatal units.

Who can participate?
In phase 1 of the study: parents of babies in neonatal units who have experienced or are currently experiencing their baby changing from being fed by tube to being fed by mouth. Health care staff in neonatal units.
In phase 3 of the study: premature babies, including twins, who do not have any medical complications and who are being fed by a tube and are ready to move to being fed by mouth, and their parents. Staff working in neonatal units

What does the study involve?
In phase 1 of the study: parents and staff will take part in a group discussion or a one-to-one interview.
In phase 3 of the study: parents will be taught about cue-based feeding and asked to feed their babies this way with support and help from the neonatal care team. The babies will monitored closely to make sure they are progressing well and gaining weight. Researchers will collect some information by reviewing the baby’s medical record and by observing care provided for babies in the study. Some (about half) of the parents will be invited to talk to researchers about their experiences of feeding their babies according to their cues, and asked for their opinion about the best way to conduct a larger study in the future that would compare cue-based feeding to feeding babies according to a set schedule. Two weeks after the baby goes home, a researcher will telephone the parents to ask how the feeding is going at home. The staff will be invited to participate in an interview with researchers who will ask about their experiences of cue-based feeding and their opinions about a future study.

What are the possible benefits and risks of participating?
It is thought that there are benefits to cue-based feeding such as babies changing to full oral feeding and being discharged home sooner. Cue-based feeding may mean that parents are more involved in their baby’s care and learning how to interpret feeding cues may help parents to understand their baby’s needs better. Taking in part in the research may help babies and parents in neonatal units in the future. Some parents find it helpful to talk about their experiences in the neonatal unit, which can be very stressful. Some parents and staff might worry that their baby is not getting enough milk. The babies in the study will be monitored very closely as are all babies in neonatal units and if they show signs that they are not feeding enough, such as not gaining weight, not being settled or having low blood sugar, the feeding plan will be changed.

Where is the study run from?
The study is being led from the University of Dundee in Scotland. The research team also includes researchers from the Open University and the University of York, clinicians from Glasgow and Great Ormond Street Hospital in London and a member from the baby charity BLISS. The study will be carried out in 3 hospitals – Ninewells Hospital in Dundee, Coventry Hospital and Exeter Hospital.

When is the study starting and how long is it expected to run for? (what is the anticipated start date and the approximate duration of the trial?)
Phase 1 of the study will start in August 2018 and finish in November 2018 (4 months).
Phase 3 will start in March 2019 and finish at the end of November 2019 (9 months)

Scientific title

Development and feasibility study of an evidence-informed manualised intervention to compare CUe-Based versus Scheduled feeding for preterm infants transitioning from tube to oral feeding in neonatal units (CuBS)



Study hypothesis

The aim of the research is to develop a manualised intervention and to assess whether it is feasible to conduct a clinical and cost-effectiveness study of cue-based versus scheduled feeding for preterm infants in neonatal units (NNUs)

Feeding of preterm babies in neonatal units


1. Work Package 1: Participants (parents and staff) recruited to this phase of the study will participate in either one focus group or one interview lasting about 1 hour. There will be no follow-up. This will form part of a telephone survey of 20 neonatal units to map and understand: i) the range of approaches to the transition from tube to oral feeding, ii) the scope of data collection systems, iii) staff training needs; and conduct qualitative research to explore parents’ and staff’s understanding and attitudes to cue-based feeding.
2. Work Package 3: Participants (babies and their parents) will be recruited when the baby is ready to transition to oral feeding. Parents will be given information about cue-based feeding and supported by staff to recognise their baby’s cues and to feed accordingly. About half of the parents will be invited to take part in one face-to-face qualitative interview about their experiences of cue-based feeding. The transition to feeding will follow a protocol for cue-based feeding i.e. the babies will be fed according to their feeding cues rather than by a schedule. Babies will be monitored according to the usual practice in the neonatal unit and followed up until 2 weeks after they are discharged home to collect data about how feeding is progressing. Some information will be collected from the baby’s medical records and there will be observations of care on specific times in the neonatal unit.

Intervention type



Drug names

Primary outcome measure

Feasibility to undertake an RCT. This will be assessed using the secondary outcome measures combined into a narrative/qualitative assessment of issues such as fidelity, dose, reach of the intervention, participants response, unexpected consequences etc (as described in the model by Moore et al 2015). The data to inform this will be collected throughout the intervention implementation (Work package 3) rather than at specific time-points. At the end of the study we will present the qualitative/narrative findings to Stakeholders who will make the decision using the ADePT framework (Bugge et al 2013).

Secondary outcome measures

1. Frequency and length of feeds (and volume for bottle fed babies) assessed by reviewing patient notes on a daily basis until 2 weeks after discharge from the neonatal unit
2. Daily weight change: assessed by reviewing patient notes on a daily basis until 2 weeks after discharge from the neonatal unit
3. Length of stay in hospital assessed by reviewing patient notes after discharge
4. Number of days to establish full oral feeding assessed by reviewing patient notes or 2-week follow-up if baby is discharged to home while still tube feeding
5. Adherence to cue-based feeding protocol assessed by reviewing patient notes/interviews/patient care observation on a daily basis
6. Feeding outcomes (method and type of milk) at discharge and 2-week follow-up
7. Important trial outcomes for a future trial assessed interviews during hospital stay
8. Feasibility of longer term follow-up assessed using interviews during hospital stay
9. Experiences and acceptability of cue-based feeding assessed using interviews during hospital stay
10. Number of infants meeting eligibility criteria and number of infants recruited assessed using research nurse recruitment logs throughout study
11. Willingness of parents to be randomised assessed using interviews during hospital stay
