Implementation of neonatal phototherapy with the BiliCocoon Bag® device in the maternity ward and impact on mother-infant separation

Abstract

Background: Free bilirubin jaundice is a frequent pathology in the neonatal period. The major complication is neurological toxicity, the most severe form of which is kernicterus. Overall, 5%-10% of jaundiced neonates require treatment. The first-line treatment is phototherapy, with intensive phototherapy being the gold standard. Other equipment is also available, including the BiliCocoon Bag®. It is a safe and controlled therapy that can be performed in the mother's room in the maternity ward, thereby avoiding separation and allowing for breast- or bottle-feeding during treatment. It is easy to install and does not require protective glasses, thus no scope or hospitalization. In our maternity ward, all neonates requiring intensive phototherapy are hospitalized in the neonatology ward.

Objective: The objective of our study was to evaluate the number of avoided hospitalizations in neonatology for free bilirubin jaundice since the introduction, according to a strict protocol, of the BiliCocoon Bag® device.

Material and method: This was a single-center retrospective cohort study using data of newborns usually collected as part of standard care. Children born in our maternity ward during an 18-month period (August 1, 2020 to January 31, 2022) were included. Causes of jaundice, age at the beginning and mode of treatment, number of sessions for each device, and length of stay were compared. Results are presented as number and percentage with median (25th-75th) or mean (extremes) values for categorical and continuous variables, respectively. A t-test was used to compare the means of the independent groups.

Results: A total of 316 newborns were included. Physiological jaundice was the main cause of jaundice. The median age for the first phototherapy treatment was 54.5 h (30-68). The 316 neonates needed 438 phototherapy sessions: 235 (74%) neonates required only one phototherapy session, 85 (36%) of them were treated with the BiliCocoon Bag®. For the 81 children who needed two or more phototherapy sessions, 19 children (23.5%) were treated by tunnel phototherapy and then the BiliCocoon Bag®, and eight children (10%) by BiliCocoon Bag® alone. The BiliCocoon Bag® enabled a relative reduction in the hospitalization rate of 38% and avoided hospitalization for approximately one third of the newborns treated. The BiliCocoon Bag® failure rate was 3.6% and the average length of stay was comparable between the two types of treatment.

Conclusion: Following a strict protocol of use, the BiliCocoon Bag® is a reliable method and a good alternative to intensive phototherapy for newborns in the maternity ward, as it avoids hospitalization and mother-infant separation.
