[Remote monitoring of neonatal jaundice in newborns with ABO hemolytic disease].

OBJECTIVE: To explore the feasibility of remote monitoring of neonatal jaundice in newborns with ABO hemolytic disease. METHODS: Forty six neonates of gestational age >35 weeks with ABO hemolytic disease admitted to Women's Hospital, Zhejiang University School of Medicine from January 20th, 2020 to February 29th, 2020 were enrolled in the study (study group). The newborns were followed up at home after discharge, the transcutaneous bilirubin (TCB) levels were measured by parents using the provided device and the results were sent to the doctor by smart phone using the installed APP. Fifty six newborns with ABO hemolytic disease admitted in 2018 who received conventional outpatient follow-up after discharge served as the control group. The demographic characteristics, total serum bilirubin (TSB) level during hospitalization, number of outpatient visit and rate of re-admission due to rebound hyperbilirubinemia were compared between the two groups. RESULTS: There were no significant differences between the two groups in gestational age, birth weight, delivery mode, gender, length of the first hospitalization, TSB level before phototherapy and before discharge, and the managements during the first hospitalization (all P>0.05). Compared with the control group, TSB level before readmission [(265±16) µmol/L vs. (295±15) µmol/L] and the number of outpatient visits (1.3±0.8 vs. 3.8±0.5) were significantly lower in the study group (all P<0.01), while the rate of readmission (17.4%vs. 12.5%) and the weight at the time of readmission[(3398±452) g vs. (3477±324) g] were not significantly different (all P>0.05). No cases of acute bilirubin encephalopathy occurred in both groups. CONCLUSIONS: The remote follow-up for neonatal jaundice at home can effectively reduce the number of outpatient visits without increasing the risk of readmission and severe neonatal hyperbilirubinemia for newborns with ABO hemolytic disease.
