Neonatal Research Network Database Japan

＜Introduction＞

A neonatal research network database was established in 2003 with a grant from the Ministry of Health, Labour and Welfare, Japan, then its operation was transferred to Non-Profit Neonatal Research Network Japan Organization, which was partly supported from the Japan Society for Neonatal Health and Development. The database provides the morbidity and the mortality of the registered infants.

＜Subjects＞

All infants who were born in the participating hospitals with gestational age less than 32 weeks and with birth weight at or less than 1500g admitted to participating facilities within 28 days after birth are registered in the database. Those infants who were born alive but died in a delivery room are also included. As of January 1, 2021, 131 perinatal centers are participating in the network.

＜Methods＞

According to a Network Database Operation Manual, all eligible infants are recorded (see details at Pediatrics 2006;118:e1130-8).
