Role of the pediatric nurse practitioner in promoting breastfeeding for late preterm infants in primary care settings

Differential low uptake of free vitamin D supplements in preterm infants: the Quebec experience

Background

Vitamin D is essential for bone mineralization, particularly in premature infants. For nearly 20 years, Quebec has offered a program of free vitamin D supplements via its public medication insurance plan Régie de l’Assurance Maladie du Québec (RAMQ). The objective of this study is to evaluate the number of preterm infants that obtained at least one bottle (50 doses) of vitamin D supplement through this program and to determine if uptake varied by gestational age.

Methods

This was a retrospective cohort study of preterm infants covered by RAMQ and born from 1998 to 2008; all infants had 1 year of follow-up data regarding supplement use. Data were extracted from the Quebec Pregnancy Cohort, a linked administrative database and were stratified by early (<34 weeks) or late gestational age premature infants. The number of infants obtaining supplements was the primary outcome and their characteristics were compared across gestational age groups. Predictors for participation (obtaining at least 1 bottle) or adherence (2 or more bottles) were identified via logistic regression (GEE).

Results

10288 infants were eligible; the percentage exposed to vitamin D was 24.5% (37.4%- early; 20.7%-late preterm infants, p < 0.001). The median number of bottles obtained was 2 for early and 1 for late preterms. For all premature infants, there was an apparent geometric decline in the infants obtaining subsequent bottles of supplements over the 12 month period. Additionally, there was a significant decline in program participation over time (OR = 0.90/year, 95% CI: 0.89-0.90) regardless of gestational age. Older or more educated mothers were positive predictors for participation. A prescription from a pediatrician significantly increased the odds of obtaining the supplement.

Conclusion

Early preterm infants were more likely to obtain the supplement post-discharge; uptake was low and decreased with time for both age categories. Specifically, targeting late preterm infants and young mothers with less education could improve vitamin D uptake.

Newborn clinical outcomes of the AWHONN late preterm infant research-based practice project

OBJECTIVE

To describe the neonatal health risks (hypothermia, hypoglycemia, hyperbilirubinemia, respiratory distress, the need for a septic workup, and feeding difficulties) experienced by late preterm infants (LPIs) from a large multisite study and determine how these risks were affected by gestational age at birth.

DESIGN

Descriptive analysis of prospective data obtained as part of the AWHONN Late Preterm Infant Research-Based Practice Project.

SETTING

Fourteen hospitals located through the United States and Canada.

PARTICIPANTS

Late preterm infants (802) born at gestational ages between 34 0/7 and 36 6/7 weeks.

METHODS

Nurses at each site obtained consent from the mother of the infant. The data about the infant were gathered from the infant's medical record.

RESULTS

Thirty-six percent of LPIs were initially cared for in a special care nursery; approximately one half of these infants were eventually transferred to a well-baby nursery. Of the 64% of LPIs initially cared for in a routine nursery, 10% were transferred to a special care unit or neonatal intensive care unit (NICU). More than one half of LPIs experienced hypothermia, hypoglycemia, feeding difficulties, hyperbilirubinemia, and respiratory distress and/or needed a septic workup. The risk for these problems was higher in infants of younger gestational ages. Thirty-two percent of the infants were bathed during the first 2 hours of life, and by 4 hours, more than two thirds had had their first bath. Fifty-two percent received kangaroo care during the first 48 hours of life.

CONCLUSION

These findings support those of smaller studies indicating that LPIs are at high risk for developing health problems during their neonatal hospitalization. Nurses may be able to ameliorate some of these health problems through early identification of problems and simple, inexpensive interventions such as avoiding early bathing and promoting kangaroo care.

Lactation and neonatal nutrition: defining and refining the critical questions

This paper resulted from a conference entitled "Lactation and Milk: Defining and refining the critical questions" held at the University of Colorado School of Medicine from January 18-20, 2012. The mission of the conference was to identify unresolved questions and set future goals for research into human milk composition, mammary development and lactation. We first outline the unanswered questions regarding the composition of human milk (Section I) and the mechanisms by which milk components affect neonatal development, growth and health and recommend models for future research. Emerging questions about how milk components affect cognitive development and behavioral phenotype of the offspring are presented in Section II. In Section III we outline the important unanswered questions about regulation of mammary gland development, the heritability of defects, the effects of maternal nutrition, disease, metabolic status, and therapeutic drugs upon the subsequent lactation. Questions surrounding breastfeeding practice are also highlighted. In Section IV we describe the specific nutritional challenges faced by three different populations, namely preterm infants, infants born to obese mothers who may or may not have gestational diabetes, and infants born to undernourished mothers. The recognition that multidisciplinary training is critical to advancing the field led us to formulate specific training recommendations in Section V. Our recommendations for research emphasis are summarized in Section VI. In sum, we present a roadmap for multidisciplinary research into all aspects of human lactation, milk and its role in infant nutrition for the next decade and beyond.

Defining lactation acuity to improve patient safety and outcomes

While substantial evidence exists identifying risks factors associated with premature weaning from breastfeeding, there are no previously published definitions of patient acuity in the lactation field. This article defines evidence-based levels of lactation acuity based on maternal and infant characteristics. Patient acuity, matching severity of illness to intensity of care required, is an important determinant of patient safety and outcomes. It is often used as part of a patient classification system to determine staffing needs and acceptable workloads in health care settings. As acuity increases, more resources, including more skilled clinicians, are needed to provide optimal care. Developing an evidence-based definition of lactation acuity can help to standardize terminology, more effectively distribute health care staff resources, encourage research to verify the validity and reliability of lactation acuity, and potentially improve breastfeeding initiation and duration rates.
