Australian and New Zealand Neonatal Network Data 2004

Abstract

The data has been collected by the Australian and New Zealand Neonatal Network (ANZNN) to improve the care of high-risk newborn infants and their families in Australian and New Zealand through collaborative audit and research. This is the fourteenth year that the ANZNN has collected data, allowing comparative reporting over time. Registration criteria - babies who meet one or more of the following criteria are eligible for registration with the ANZNN: * born at less than 32 completed weeks gestation, or * weighed less than 1,500 grams at birth, or * received assisted ventilation (mechanical ventilation) including intermittent positive pressure ventilation (IPPV) or continuous positive pressure (CPAP) for four or more consecutive hours, or died while receiving mechanical ventilation prior to four hours of age, or * received major surgery (surgery that involved opening a body cavity), or * received therapeutic hypothermia. Babies who were discharged home and readmitted to neonatal intensive care unit (NICU) during their neonatal period were not eligible for registration in the ANZNN. Babies who were discharged home and readmitted to a NICUS during their neonatal period are not registered to ANZNN. The hospital of registration for a baby is the first level III NICU that the baby remained in for four or more hours during the first 28 days of life. Babies who received their entire care in a level II hospital or who were not transferred to a level III NICU during the first 28 days were registered to the first level II centre that they remained in for four or more hours. In 2004, 7,399 babies registered to ANZNN in all NICUs in Australia and New Zealand and 361 babies registered to ANZNN in 15 level II nurseries. Data in this collection include: maternal characteristics (maternal age, presenting antenatal problem, antenatal corticosteroid use, method of birth and place of birth) and baby's characteristics (baby gender, transfer after birth, multiple births, congenital abnormalities, apgar score at birth, exogenous surfactant, respiratory assistance, type of assisted ventilation, ventilation in babies born at less than 32 weeks gestation, ventilation in babies born at 32 to 36 weeks gestation, ventilation in babies born at term, chronic lung disease, pulmonary air leak, cerebral ultrasound, neonatal surgery, necrotising enterocolitis, neonatal infection,, transfer from level III NICUs to other units, length of stay until discharge home and survival of the ANZNN registrants). https://npesu.unsw.edu.au/data-collection/australian-new-zealand-neonatal-network-anznn
