Objective To assess the association of short-term neonatal outcomes with cross-site working of multiple healthcare professional teams between a level 3 and a level 1 neonatal unit. Design Retrospective cohort study. Setting A level 1 neonatal unit in London. Patients All infants admitted to the neonatal unit, between 2010 and 2021. Interventions The clinical service was rearranged in 2014 with the introduction of cross-site working between the level 1 unit and a level 3 unit of neonatal doctors, nurses and allied healthcare professionals. Main outcome measures Admission of infants with a temperature less than 36°C, length of stay and time to first consultation by a senior team member. Results A total of 4418 infants were admitted during the study period. The percentage of infants delivered at a gestation below 32 weeks was higher in the pre-cross-site period (8.9%) compared with the cross site period (3.6%, p<0.001). The percentage of infants with an Apgar score less than 8 at 10 min was higher in the pre-cross-site period (6.2%) compared with the cross-site period (3.4%, p=0.001). More infants were admitted with a temperature less than 36°C in the pre-cross site period (12.3%) compared with the cross site period (3.7%, p<0.001). The median (IQR) duration of time to first consultation by a senior team member was higher in the pre-cross-site period (1 (0.5–2.6) hours) compared with the cross-site period (0.5 (0.2–1.3) hours) (p<0.001). The median (IQR) length of stay was 4 (2–11) days in the pre-cross-site period and decreased to 2 (1–4) days in the cross-site period (p<0.001). Conclusions Cross-site working was associated with lower rates of admission hypothermia, shorter duration of stay and earlier first senior consultation.
