Factors affecting the mortality of sick newborns admitted to intensive care units.
In order to provide better understanding of the factors affecting the mortality of sick newborns in the Taipei metropolitan area, data of newborns admitted to the intensive care units (ICU) were analyzed retrospectively according to the hospital type of care. Fourteen of the 19 hospitals with an ICU admitting sick newborns joined the data collection: 3 were local hospitals, 7 were regional hospitals and 4 were medical centers. Perinatal and neonatal data of 1083 sick newborns were analyzed: 60% were premature newborns and 58% were male newborns. The maternal referral rate was 7.8% and the neonatal transport rate was 36.2%. Fifty-nine percent of very low birth-weight newborns and 66% of extremely low birth-weight (ELBW) newborns were admitted to the medical centers. The two most common illnesses were perinatal asphyxia and respiratory distress syndrome. About 40% needed assisted ventilation. There were higher incidence of maternal referral, fetal distress, resuscitation in the delivery room, perinatal asphyxia, and necrotizing enterocolitis; lower incidence of meconium aspiration syndrome, sepsis and pneumothorax in newborns admitted to the medical center than those newborns admitted to other hospitals. A total of 153 newborns (14%) died. The most common cause of death was sepsis (22.9%). Multivariate logistic regression analysis revealed that factors significantly related to the mortality were gestational age < 28 weeks, congenital anomaly, sepsis, resuscitation in the delivery room, neonatal transport, congenital heart disease, hospital type of care, ELBW, pneumothorax and high-risk pregnancy. The results of the study stress the importance of regionalization of perinatal and neonatal care, organization of neonatal transport system, newborn resuscitation training, infection control, and delicate ventilatory care in the further improvement of the outcome of sick newborns in the Taipei metropolitan area.
