Using a WeChat mini-program-based lactation consultant intervention to increase the consumption of mother's own milk...

The benefits of mother's own milk (MOM) for preterm infants have been widely recognized. Many studies have shown that the rate of breastfeeding of premature infants remains very low. Although many studies use measures to promote breastfeeding, few high-quality cluster randomized controlled studies have evaluated the effectiveness of these measures. WeChat is an instant messaging software for smart terminals, and WeChat mini-programs have been widely used to promote health and self-management in China. Based on this background, we designed a randomized controlled study based on WeChat mini-programs to promote MOM feeding of premature infants in the neonatal intensive care unit (NICU).

This study will evaluate the effectiveness of WeChat mini-programs to increase the consumption of MOM feeding in twelve NICUs in Jiangsu Province, namely, six "intervention" NICUs and six "control" NICUs. The study process is as follows: (1) design and preparation, (2) NICU recruitment and training, (3) interpretation and analysis of baseline data, (4) quality control implementation process, and (5) data analysis feedback and publication of study reports. The primary outcome is the proportion of MOM feeding of premature infants during NICU hospitalization. The secondary outcomes are as follows: (1) time to initiation of MOM feeding (hours) and proportion of first-time MOM feeding (%), (2) duration of parenteral nutrition (days), (3) time to total gastrointestinal feeding (days), (4) hospitalization time and hospitalization cost, and (5) incidence of complications (necrotizing enterocolitis, bronchopulmonary dysplasia, feeding intolerance, late-onset sepsis, retinopathy of prematurity).

This study is the first cluster randomized controlled trial on the intervention of using a WeChat mini-program-based lactation consultant for premature infants in the NICU in China. We hope this study can improve the consumption of MOM by NICU premature infants during hospitalization through the intervention of WeChat mini-programs.
