How recruitment works
Families are approached by their local neonatal research team.
Babies are recruited while receiving care in a participating hospital. Families do not need to search for a centre, arrange a referral or contact another hospital.
For trial questions: participating families should contact the research nurse at their baby’s local hospital.
For clinical advice: contact your baby’s local clinical service, neonatal team, GP or NHS 111. Call 999 in an emergency.
Participating hospitals
BALLOON is recruiting through neonatal teams across the UK.
See the hospitals currently listed as participating BALLOON sites and their distribution across the UK.
