There was a 27% drop in the number of babies who needed intensive care treatment at the National Maternity Hospital last year.
The hospital's annual report shows 1,517 infants were admitted to the neonatal intensive care unit in 2018.
That's the lowest number of admissions since 2012.
The fall is being attributed to the introduction of a new system of early identification of infants at risk of infection.
Director of Neonatal Intensive Care Dr Claudine Vavasseur says "This remarkable reduction shows the importance of constantly reviewing work practices and introducing changes as a result".
Dr Vavasseur says "It reduces the incidence of separation of infants from their mothers, facilitating bonding and breast-feeding, as well as saving staff time".
