This dataset comprises anonymised qualitative interviews with neonatal health professionals exploring barriers and facilitators to implementing an early supported transfer to home intervention for late preterm infants. Participants were drawn from NHS neonatal units and community services across the North West of England. The dataset provides insight into the organisational, cultural, and clinical factors shaping implementation of neonatal pathways. Due to ethical and confidentiality considerations, full interview transcripts are not openly available, as participants did not consent to public data sharing. Anonymised excerpts supporting key findings are included in the associated publication: Hamer et al. (2025) Professional perceptions of barriers and facilitators from the implementation of a neonatal early supported transfer to home intervention for late preterm infants: A qualitative study, Journal of Neonatal Nursing, 31(1), 275–281.
