The eligible newborns will be randomized into two groups: the study group (innovative strategy) and the controlled group (traditional strategy).~The innovative strategy included the ETCOc measurement in the risk evaluating process and the Internet Plus approach in the follow-up process.
In this prospective multi-center randomized clinical trial, a new follow-up strategy for neonatal jaundice after discharge will be evaluated. It is based on current risk factors of neonatal hyperbilirubinemia, added with the rate of bilirubin production (exhaled carbon monoxide measurement) as a new indicator,and incorporated with Internet Plus technology. Traditional methods following the Chinese guideline for neonatal hyperbilirubinemia were applied in the control group. The morbidity of BIND, the number of outpatient follow-up after discharge and the convenience will be compared between the two groups. The accuracy, effectiveness, safety and convenience of the study strategy will be testified.
