Study protocol for reducing disparity in receipt of mother's own milk in very low birth weight infants (ReDiMOM): a randomized trial to improve adherence to sustained maternal breast pump use

BACKGROUND

Black very low birth weight (VLBW; < 1500 g birth weight) and very preterm (VP, < 32 weeks gestational age, inclusive of extremely preterm, < 28 weeks gestational age) infants are significantly less likely than other VLBW and VP infants to receive mother's own milk (MOM) through to discharge from the neonatal intensive care unit (NICU). The costs associated with adhering to pumping maternal breast milk are borne by mothers and contribute to this disparity. This randomized controlled trial tests the effectiveness and cost-effectiveness of an intervention to offset maternal costs associated with pumping.

METHODS

This randomized control trial will enroll 284 mothers and their VP infants to test an intervention (NICU acquires MOM) developed to facilitate maternal adherence to breast pump use by offsetting maternal costs that serve as barriers to sustaining MOM feedings and the receipt of MOM at NICU discharge. Compared to current standard of care (mother provides MOM), the intervention bundle includes three components: a) free hospital-grade electric breast pump, b) pickup of MOM, and c) payment for opportunity costs. The primary outcome is infant receipt of MOM at the time of NICU discharge, and secondary outcomes include infant receipt of any MOM during the NICU hospitalization, duration of MOM feedings (days), and cumulative dose of MOM feedings (total mL/kg of MOM) received by the infant during the NICU hospitalization; maternal duration of MOM pumping (days) and volume of MOM pumped (mLs); and total cost of NICU care. Additionally, we will compare the cost of the NICU acquiring MOM versus NICU acquiring donor human milk if MOM is not available and the cost-effectiveness of the intervention (NICU acquires MOM) versus standard of care (mother provides MOM).

DISCUSSION

This trial will determine the effectiveness of an economic intervention that transfers the costs of feeding VLBWand VP infants from mothers to the NICU to address the disparity in the receipt of MOM feedings at NICU discharge by Black infants. The cost-effectiveness analysis will provide data that inform the adoption and scalability of this intervention.

Human Milk Provision Experiences, Goals, and Outcomes for Teen Mothers with Low-Birth-Weight Infants in the Neonatal Intensive Care Unit

INTRODUCTION

Breastfeeding rates are virtually unknown for teen mothers whose low-birth-weight (LBW; <2500 gm) infants are hospitalized in the neonatal intensive care unit (NICU). The objective was to examine the infant feeding experiences, goals, and outcomes of teen mothers of LBW infants.

METHODS

We conducted a multimethod study using a qualitative research design, survey, and infant medical records. The primary data source was individual interviews conducted with teen mothers of LBW infants hospitalized in a tertiary NICU. Content analysis and descriptive statistics were used for data analysis.

RESULTS

All 15 teen mothers (12 black, 3 Hispanic) wanted what was best for their infants and initiated lactation by breast pump. However, maintaining lactation was challenging and the following barriers were identified: fear of being judged; body image issues; influence of the maternal grandmother; and disorganized thought processes about combining pumping with returning to school or work. Despite these barriers, 50% of the teen mothers met their goals for human milk provision at NICU discharge.

CONCLUSION

Most of the teen mothers' lactation barriers reflected their adolescent developmental stage. Potential interventions are identified and include focus groups with teen mothers and maternal grandmothers and lactation support by NICU-based teen breastfeeding peer counselors.

Breast pump suction patterns that mimic the human infant during breastfeeding: greater milk output in less time spent pumping for breast pump-dependent mothers with premature infants

OBJECTIVE

The objective of this study was to compare the effectiveness, efficiency, comfort and convenience of newly designed breast pump suction patterns (BPSPs) that mimic sucking patterns of the breastfeeding human infant during the initiation and maintenance of lactation.

STUDY DESIGN

In total, 105 mothers of premature infants ≤34 weeks of gestation were randomly assigned to 1 of 3 groups within 24 h post-birth. Each group tested two BPSPs; an initiation BPSP was used until the onset of lactogenesis II (OOL-II) and a maintenance BPSP was used thereafter.

RESULT

Mothers who used the experimental initiation and the standard 2.0 maintenance BPSPs (EXP-STD group) demonstrated significantly greater daily and cumulative milk output, and greater milk output per minute spent pumping.

CONCLUSION

BPSPs that mimic the unique sucking patterns used by healthy-term breastfeeding infants during the initiation and maintenance of lactation are more effective, efficient, comfortable and convenient than other BPSPs.
