Prepregnancy Body Mass Index Is Associated with Time-Dependent Changes in Secretory Activation Measures During the First 7 Days Postpartum in Breast Pump-dependent Mothers of Premature Infants

Background: Little is known about the biology of secretory activation (SA) in overweight and obese (OW/OB) mothers who are breast pump dependent with a premature infant in the neonatal intensive care unit. Objective: To compare time-dependent changes in daily pumped milk volume, maternal milk sodium (Na) concentration, and Na-to-potassium (K) ratios (Na:K) in the first 14 days postpartum in breast pump-dependent mothers with prepregnancy body mass index (BMI) <27 and BMI ≥27 kg/m². Design/Methods: This secondary analysis for 39 subjects, 44% (n = 17) with prepregnancy BMI <27 and 56% (n = 22) with BMI ≥27, included transformed data of outcome measures, chi-square, t-tests, and growth curve models. Results: For days 1-7, daily pumped milk volume increased significantly more rapidly for mothers with BMI <27 (65.82 mL/d) versus BMI ≥27 (33.08 mL/d), but the daily rate of change in pumped milk volume during days 8-14 was not statistically different. Daily milk Na concentration decreased significantly faster in BMI <27 (-3.93 mM/d) versus BMI ≥27 (-2.00 mM/day) during days 1-7, but was not significantly different for days 8-14. No statistical differences were noted for Na:K ratio for either time period. Conclusion: These data add biologic evidence to previous research, suggesting delayed or impaired SA in OW/OB mothers, and suggest that the window of opportunity for research and clinical interventions is days 1-7 postpartum in this population.

Measures of Secretory Activation for Research and Practice: An Integrative Review

Background: Maternal concern about inadequate milk volume commonly emerges in the first 2 weeks postpartum, a critical lactation period that includes secretory activation. This review summarizes the biology of secretory activation and evaluates the accuracy and feasibility of published measures of secretory activation. Materials and Methods: A systematic search of measures of secretory activation for mothers of healthy term and preterm infants yielded 62 abstracts. Following additional screening, 15 publications qualified for quantitative synthesis review and were evaluated with respect to accuracy (validated with another measure of secretory activation in the same mother) and feasibility (accessibility, cost, and ease of use). Results:Maternal perception of milk coming in (MP) is the most feasible measure, but its accuracy has not been established. Patterns of increase in maternal milk volume have been validated with maternal milk-borne biomarkers in breastfeeding, and breast pump-dependent mothers and normal values have been published. Accuracy of serial maternal urinary lactose concentrations has not been established for secretory activation and lacks feasibility. Maternal milk biomarkers are the accurate standard to which other measures are compared but currently lack feasibility for routine use. Conclusions: Use of secretory activation measures can personalize lactation care by matching maternal risk with appropriate diagnostics. Priorities for research and practice include validation of MP as a population-based screening tool, implementation of techniques that measure patterns of increase in milk volume for moderate risk populations, and the development of milk biomarker science for point-of-care use in the most complicated lactation scenarios.

Priorities for Contraception and Lactation Among Breast Pump-Dependent Mothers of Premature Infants in the Neonatal Intensive Care Unit

Objective: Determine the knowledge and priorities for postpartum contraception and lactation in mothers of premature infants. Design: Twenty-five mothers of premature infants (mean gestational age = 29.9 weeks) hospitalized in a tertiary neonatal intensive care unit (NICU) participated in a multi-methods study using a multiple-choice contraceptive survey and qualitative interview in the first 2 weeks postpartum. Data were analyzed using content analysis and descriptive statistics. Results: Although 60% of mothers planned to use contraception, all questioned the timing of postpartum contraceptive counseling while recovering from a traumatic birth and coping with the critical health status of the infant. All mothers prioritized providing mothers' own milk (MOM) over the use of early hormonal contraception because they did not want to "take any risks" with their milk. They had limited knowledge of risks for repeat preterm birth (e.g., prior preterm birth: n = 13, 52%; multiple birth: n = 9, 36%; no knowledge: n = 3, 12%); only two mothers (0.08%) were counseled about the risks of a short interpregnancy interval. Conclusion: The context of the infants' NICU admission and the mother's desire to "do what is best for the baby" by prioritizing MOM should be integrated into postpartum contraceptive counseling for this population.

Influence of own mother's milk on bronchopulmonary dysplasia and costs

BACKGROUND

Human milk from the infant's mother (own mother's milk; OMM) feedings reduces the risk of several morbidities in very low birthweight (VLBW) infants, but limited data exist regarding its impact on bronchopulmonary dysplasia (BPD).

OBJECTIVE

To prospectively study the impact of OMM received in the neonatal intensive care unit (NICU) on the risk of BPD and associated costs.

DESIGN/METHODS

A 5-year prospective cohort study of the impact of OMM dose on growth, morbidity and NICU costs in VLBW infants. OMM dose was the proportion of enteral intake that consisted of OMM from birth to 36 weeks postmenstrual age (PMA) or discharge, whichever occurred first. BPD was defined as the receipt of oxygen and/or positive pressure ventilation at 36 weeks PMA. NICU costs included hospital and physician costs.

RESULTS

The cohort consisted of 254 VLBW infants with mean birth weight 1027±257 g and gestational age 27.8±2.5 weeks. Multivariable logistic regression demonstrated a 9.5% reduction in the odds of BPD for every 10% increase in OMM dose (OR 0.905 (0.824 to 0.995)). After controlling for demographic and clinical factors, BPD was associated with an increase of US$41 929 in NICU costs.

CONCLUSIONS

Increased dose of OMM feedings from birth to 36 weeks PMA was associated with a reduction in the odds of BPD in VLBW infants. Thus, high-dose OMM feeding may be an inexpensive, effective strategy to help reduce the risk of this costly multifactorial morbidity.

Health Care Workers' Beliefs and Practices Around Pap Screening for Adolescents Seeking Contraception

Adolescents often avoid seeing a health care provider to obtain contraception because they do not want to undergo a pelvic exam and Pap screening for fear of stress, pain or embarrassment. The purpose of this quality improvement project was to study health care workers, attitudes and beliefs about Pap screening and to educate them on the latest evidence-based guidelines, with the hope of ultimately decreasing unnecessary screening. Results showed a modest reduction in the frequency of Pap screening; however, many adolescents continued to undergo unnecessary Pap screening. The reluctance of health care workers to change their practice demonstrates the need for better methods of translating evidence-based guidelines into practice.

Cost savings of human milk as a strategy to reduce the incidence of necrotizing enterocolitis in very low birth weight infants

BACKGROUND

Necrotizing enterocolitis (NEC) is a costly morbidity in very low birth weight (VLBW; <1,500 g birth weight) infants that increases hospital length of stay and requires expensive treatments.

OBJECTIVES

To evaluate the cost of NEC as a function of dose and exposure period of human milk (HM) feedings received by VLBW infants during the neonatal intensive care unit (NICU) hospitalization and determine the drivers of differences in NICU hospitalization costs for infants with and without NEC.

METHODS

This study included 291 VLBW infants enrolled in an NIH-funded prospective observational cohort study between February 2008 and July 2012. We examined the incidence of NEC, NICU hospitalization cost, and cost of individual resources used during the NICU hospitalization.

RESULTS

Twenty-nine (10.0%) infants developed NEC. The average total NICU hospitalization cost (in 2012 USD) was USD 180,163 for infants with NEC and USD 134,494 for infants without NEC (p = 0.024). NEC was associated with a marginal increase in costs of USD 43,818, after controlling for demographic characteristics, risk of NEC, and average daily dose of HM during days 1-14 (p < 0.001). Each additional ml/kg/day of HM during days 1-14 decreased non-NEC-related NICU costs by USD 534 (p < 0.001).

CONCLUSIONS

Avoidance of formula and use of exclusive HM feedings during the first 14 days of life is an effective strategy to reduce the risk of NEC and resulting NICU costs in VLBW infants. Hospitals investing in initiatives to feed exclusive HM during the first 14 days of life could substantially reduce NEC-related NICU hospitalization costs.

Effects of the 2011 flood in Thailand on birth outcomes and perceived social support

OBJECTIVE

To determine the effects of displacement due to flooding during pregnancy on birth outcomes (infant birth weight and gestational age) and the moderating effect of perceived social support on the relationship between displacement and birth outcomes.

DESIGN

A descriptive, longitudinal study.

SETTING

A university-affiliated hospital in Pathum Thani, Thailand.

PARTICIPANTS

Pregnant women (N = 175) in the third trimester that had uncomplicated pregnancies and no history of mental illness.

METHODS

During pregnancy, the participants completed standardized measurements of depression symptoms, perceived social support, and questionnaires concerning the effect of the flood. After giving birth, infant birth weight and gestational age at birth were retrieved from delivery records.

RESULTS

Seventy percent (n = 123) of the participants experienced displacement during the flood. The displaced women had a mean infant birth weight of 175 grams less than that of the nondisplaced women, t(173) = -2.38, p = .02, whereas infant gestational age was not different. Displacement and other variables explained approximately 8% of the variance in infant birth weight. The interaction term between displacement and perceived social support was statistically significant and additionally explained the variance in infant birth weight, F(6, 168) = 3.24, p = .005.

CONCLUSION

Being displaced during pregnancy due to a natural disaster affected fetal growth rather than length of gestation. Health care providers should closely monitor maternal weight gain and fetal growth of pregnant women who experience displacement. Among the displaced women, social support was associated with higher infant birth weight; therefore, high levels of perceived social support may be protective for pregnant women who experience stressful events such as displacement from flooding.

Economic benefits and costs of human milk feedings: a strategy to reduce the risk of prematurity-related morbidities in very-low-birth-weight infants

Infants born at very low birth weight (VLBW; birth weight <1500 g) are at high risk of mortality and are some of the most expensive patients in the hospital. Additionally, VLBW infants are susceptible to prematurity-related morbidities, including late-onset sepsis, bronchopulmonary dysplasia (BPD), necrotizing enterocolitis, and retinopathy of prematurity, which have short- and long-term economic consequences. The incremental cost of these morbidities during the neonatal intensive care unit (NICU) hospitalization is high, ranging from $10,055 (in 2009 US$) for late-onset sepsis to $31,565 for BPD. Human milk has been shown to reduce both the incidence and severity of some of these morbidities and, therefore, has an indirect impact on the cost of the NICU hospitalization. Furthermore, human milk may also directly reduce NICU hospitalization costs, independent of the indirect impact on the incidence and/or severity of these morbidities. Although there is an economic cost to both the mother and institution for providing human milk during the NICU hospitalization, these costs are relatively low. This review describes the total cost of the initial NICU hospitalization, the incremental cost associated with these prematurity-related morbidities, and the incremental benefits and costs of human milk feedings during critical periods of the NICU hospitalization as a strategy to reduce the incidence and severity of these morbidities.

Management of breastfeeding during and after the maternity hospitalization for late preterm infants

Among infants born moderately and late preterm or early term, the greatest challenge for breastfeeding management is the late preterm infant (LPI) who is cared for with the mother in the maternity setting. Breastfeeding failure among LPIs and their mothers is high. Evidence-based strategies are needed to protect infant hydration and growth, and the maternal milk supply, until complete feeding at breast can be established. This article reviews the evidence for lactation and breastfeeding risks in LPIs and their mothers, and describes strategies for managing these immaturity-related feeding problems. Application to moderately and early preterm infants is made throughout.

Breastfeeding peer counselors as direct lactation care providers in the neonatal intensive care unit

In 2005, the Level III neonatal intensive care unit (NICU) at Rush University Medical Center initiated a demonstration project employing breastfeeding peer counselors, former parents of NICU infants, as direct lactation care providers who worked collaboratively with the NICU nurses. This article describes the conceptualization, implementation, and evaluation of this program and provides templates for other NICUs that wish to incorporate breastfeeding peer counselors with the goal of providing quality, evidence-based lactation care.

The institutional cost of acquiring 100 mL of human milk for very low birth weight infants in the neonatal intensive care unit

BACKGROUND

Human milk from the biologic mother (HM) reduces disease burden and associated costs of care during and after neonatal intensive care unit (NICU) hospitalization for very low birth weight (VLBW; birth weight < 1500 g) infants, when compared to feedings of donor human milk (DHM) or commercial formula (CF). However, compared to DHM and CF, little is known about the institutional cost to acquire HM from the biologic mother.

OBJECTIVE

This study aimed to determine the institutional cost of acquiring HM for VLBW infant feedings during the NICU hospitalization.

METHODS

This analysis examined 157 maternal pumping records from a prospective cohort study evaluating health outcomes and cost of HM feedings for VLBW infants. The costs for the breast pump rental fee, 1-time pump kit purchase, and disposable food-grade containers for storing expressed HM were evaluated using standard cost analysis techniques.

RESULTS

The median cost of acquiring 100 mL of HM varied from $0.51 when mothers pumped ≥ 700 mL daily to $7.93 for those who pumped < 100 mL daily. Mothers who pumped ≥ 100 mL daily had lower acquisition cost compared to both DHM ($14.84/100 mL) and CF ($3.18/100 mL). For mothers who pumped > 100 mL daily, the exact day of pumping where the cost of HM was less expensive than DHM or CF was 4 to 7 days and 6 to 19 days, respectively.

CONCLUSION

Human milk from the biologic mother has lower acquisition cost than DHM and CF when mothers provided ≥ 100 mL daily and pumped for a sufficient number of days (range, 4-19). Neonatal intensive care units should prioritize resources to ensure that mothers achieve this daily milk volume.

"I have faith in my milk": the meaning of milk for mothers of very low birth weight infants hospitalized in the neonatal intensive care unit

BACKGROUND

Mothers who deliver a premature infant often choose to provide milk because it is the "one thing that only the mother can do" to optimize her infant's outcome, helps mothers feel a connection with their infants, and helps relieve the guilt associated with the preterm birth.

OBJECTIVE

The purpose of this study was to describe the meaning of milk for mothers who are providing milk for their very low birth weight (VLBW; < 1500 g) infants hospitalized in the neonatal intensive care unit (NICU).

METHODS

Using a qualitative descriptive design, in-depth semistructured interviews were conducted with 23 mothers of VLBW infants hospitalized in a level III NICU. Mothers were asked to share their perceptions about what providing milk meant to them.

RESULTS

Mothers had faith in the healing properties of their milk and equated providing milk with "giving life" to their infants, mitigating the effects of complications, keeping their infants healthy and stable, and helping themselves address the feelings of failure and guilt associated with the premature birth. Mothers' faith in their milk to achieve these outcomes was a maternal motivator to continue pumping, even for mothers who had not intended to provide milk or who experienced the paradox of disliking pumping but wanting to provide their milk.

CONCLUSION

The experiences of these mothers reflect the importance of acknowledging mothers' faith in the healing properties of their milk as a motivating factor for sustaining lactation while coping with the stress and anxiety inherent during the infant's NICU hospitalization.

Impact of early human milk on sepsis and health-care costs in very low birth weight infants

OBJECTIVE

To study the incidence of sepsis and neonatal intensive care unit (NICU) costs as a function of the human milk (HM) dose received during the first 28 days post birth for very low birth weight (VLBW) infants.

STUDY DESIGN

Prospective cohort study of 175 VLBW infants. The average daily dose of HM (ADDHM) was calculated from daily nutritional data for the first 28 days post birth (ADDHM-Days 1-28). Other covariates associated with sepsis were used to create a propensity score, combining multiple risk factors into a single metric.

RESULT

The mean gestational age and birth weight were 28.1 ± 2.4 weeks and 1087 ± 252 g, respectively. The mean ADDHM-Days 1-28 was 54 ± 39 ml kg(-1) day(-1) (range 0-135). Binary logistic regression analysis controlling for propensity score revealed that increasing ADDHM-Days 1-28 was associated with lower odds of sepsis (odds ratio 0.981, 95% confidence interval 0.967-0.995, P=0.008). Increasing ADDHM-Days 1-28 was associated with significantly lower NICU costs.

CONCLUSION

A dose-response relationship was demonstrated between ADDHM-Days 1-28 and a reduction in the odds of sepsis and associated NICU costs after controlling for propensity score. For every HM dose increase of 10 ml kg(-1) day(-1), the odds of sepsis decreased by 19%. NICU costs were lowest in the VLBW infants who received the highest ADDHM-Days 1-28.

Improving satisfaction with care and reducing length of stay in an obstetric triage unit using a nurse-midwife-managed model of care

INTRODUCTION

A quality improvement project was initiated at a tertiary-care center in a suburban area of the northeastern United States to determine whether length of stay and patient satisfaction in an obstetric triage unit could be improved by using a certified nurse-midwife (CNM) to manage and organize care in the triage unit.

METHODS

Patient satisfaction was measured using a previously validated instrument that consisted of 6 items using a 6-point Likert-type scale. The items measured patient satisfaction with: wait time for provider, information given, amount of time spent with provider, length of visit, overall care received, and overall triage experience. Patient satisfaction was measured before (n = 37) and after implementing CNM-managed care (n = 66) in an obstetrical triage unit. Length of stay in the triage unit was measured during standard care (n = 121) and after the implementation of CNM-managed care (n = 151) by recording the number of minutes women spent in the triage unit.

RESULTS

Participants in the CNM-managed care group reported increased patient satisfaction with care in 5 of the 6 aspects of satisfaction that were measured, including wait time for provider (P = .01), time spent with provider (P = .01), length of visit (P = .04), overall care received (P = .04), and overall triage experience (P = .01). The length of stay was significantly shorter for the women in the CNM-managed group (mean = 94.7 minutes; standard deviation [SD] 50.1) than for the women in the standard care model (mean = 122 minutes; SD = 66.8; P < .01).

DISCUSSION

The findings from this project suggest that a CNM-managed obstetric triage unit can improve satisfaction with care during the triage experience and reduce length of stay in the triage unit.

Supporting breastfeeding in the neonatal intensive care unit: Rush Mother's Milk Club as a case study of evidence-based care

The translation of the evidence for the use of human milk (HM) in the neonatal intensive care unit (NICU) into best practices, toolkits, policies and procedures, talking points, and parent information packets is limited, and requires use of evidence-based quality indicators to benchmark the use of HM, consistent messaging by the entire NICU team about the importance of HM for infants in the NICU, establishing procedures that protect maternal milk supply, and incorporating lactation technologies that take the guesswork out of HM feedings and facilitate milk transfer during breastfeeding.

Cost of morbidities in very low birth weight infants

OBJECTIVE

To determine the association between direct costs for the initial neonatal intensive care unit hospitalization and 4 potentially preventable morbidities in a retrospective cohort of very low birth weight (VLBW) infants (birth weight <1500 g).

STUDY DESIGN

The sample included 425 VLBW infants born alive between July 2005 and June 2009 at Rush University Medical Center. Morbidities included brain injury, necrotizing enterocolitis, bronchopulmonary dysplasia, and late-onset sepsis. Clinical and economic data were retrieved from the institution's system-wide data and cost accounting system. A general linear regression model was fit to determine incremental direct costs associated with each morbidity.

RESULTS

After controlling for birth weight, gestational age, and sociodemographic characteristics, the presence of brain injury was associated with a $12048 (P = .005) increase in direct costs; necrotizing enterocolitis, with a $15 440 (P = .005) increase; bronchopulmonary dysplasia, with a $31565 (P < .001) increase; and late-onset sepsis, with a $10055 (P < .001) increase. The absolute number of morbidities was also associated with significantly higher costs.

CONCLUSION

This study provides collective estimates of the direct costs incurred during neonatal intensive care unit hospitalization for these 4 morbidities in VLBW infants. The incremental costs associated with these morbidities are high, and these data can inform future studies evaluating interventions aimed at preventing or reducing these costly morbidities.

Healthcare providers' perceptions of breastfeeding peer counselors in the neonatal intensive care unit

In this qualitative descriptive study we examined the perceptions of 17 neonatal intensive care unit (NICU) healthcare providers (nurses, neonatologists, lactation consultants, and dietitians) about the role of breastfeeding peer counselors who were mothers of former NICU infants and who provided primary lactation care in the NICU. Findings revealed that the healthcare providers respected the peer counselors' lactation expertise and identified three critical elements that contributed to the effectiveness of the peer counseling program: having a champion for the program, counselors being mothers of former NICU infants, and a NICU culture supportive of using human milk. Healthcare providers thought the peer counselors enhanced care of the infant by empowering mothers to provide milk and by facilitating and modeling positive patterns of maternal-infant interactions.

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.

"They've walked in my shoes": mothers of very low birth weight infants and their experiences with breastfeeding peer counselors in the neonatal intensive care unit

The effectiveness of the breastfeeding peer counselor role is thought to be embedded in the relationship between new and experienced mothers. In this study, new mothers of very low birth weight infants emphasized that one of the most important aspects of their relationship with the breastfeeding peer counselors is the peer or shared experience of how difficult it can be to provide milk and breastfeed while coping with the emotional stress of having an infant in the neonatal intensive care unit. This study provides evidence for the promotion and facilitation of lactation for mothers of neonatal intensive care unit infants through the use of breastfeeding peer counselors who are peers by virtue of the shared experience of providing milk for an infant hospitalized in the neonatal intensive care unit.

A pilot study to determine the safety and feasibility of oropharyngeal administration of own mother's colostrum to extremely low-birth-weight infants

Own mother's colostrum is rich in cytokines and other immune agents that may stimulate oropharyngeal-associated lymphoid tissue if administered oropharyngeally to extremely low-birth-weight (ELBW) infants during the first days of life when enteral feeding is contraindicated. However, the safety and feasibility of the oropharyngeal route for the administration of colostrum have not been determined.

PURPOSE

To determine the safety of oropharyngeal administration of own mother's colostrum to ELBW infants in first days of life. A secondary purpose was to investigate the feasibility of (1) delivering this intervention to ELBW infants in the first days of life and (2) measuring concentrations of secretory immunoglobulin A and lactoferrin in tracheal aspirate secretions and urine of these infants.

SUBJECTS

Five ELBW infants (mean birth weight and gestational age = 657 g and 25.5 weeks, respectively).

DESIGN

Quasi-experimental, 1 group, pretest-posttest design.

METHODS

Subjects received 0.2 mL of own mother's colostrum administered oropharyngeally every 2 hours for 48 consecutive hours, beginning at 48 hours of life. Concentrations of secretory immunoglobulin A and lactoferrin were measured in tracheal aspirates and urine of each subject at baseline, at the completion of the intervention and again 2 weeks later.

RESULTS

All infants completed the entire treatment protocol, each receiving 24 treatments. A total of 15 urine specimens were collected and 14 were sufficient in volume for analysis. A total of 15 tracheal aspirates were collected, but only 7 specimens (47%) were sufficient in volume for analysis. There was wide variation in concentrations of secretory immunoglobulin A and lactoferrin in urine and tracheal aspirates among the 5 infants; however, several results were outside the limits of assay detection. All infants began to suck on the endotracheal tube during the administration of colostrum drops. Oxygen saturation measures remained stable or increased slightly during each of the treatment sessions. There were no episodes of apnea, bradycardia, hypotension, or other adverse effects associated with the administration of colostrum.

CONCLUSIONS

Oropharyngeal administration of own mother's colostrum is easy, inexpensive, and well-tolerated by even the smallest and sickest ELBW infants. Future research should continue to examine the optimal procedure for measuring the direct immune effects of this therapy, as well as the clinical outcomes such as infections, particularly ventilator-associated pneumonia.

The initial maternal cost of providing 100 mL of human milk for very low birth weight infants in the neonatal intensive care unit

OBJECTIVES

Human milk (HM) feeding is associated with lower incidence and severity of costly prematurity-specific morbidities compared to formula feeding in very low birth weight (VLBW; <1,500 g) infants. However, the costs of providing HM are not routinely reimbursed by payers and can be a significant barrier for mothers. This study determined the initial maternal cost of providing 100 mL of HM for VLBW infants during the early neonatal intensive care unit (NICU) stay.

METHODS

This secondary analysis examined data from 111 mothers who provided HM for their VLBW infants during the early NICU stay. These data were collected during a multisite, randomized clinical trial where milk output and time spent pumping were recorded for every pumping session (n = 13,273). The cost analysis examined the cost of the breast pump rental, pump kit, and maternal opportunity cost (an estimate of the cost of maternal time).

RESULTS

Mean daily milk output and time spent pumping were 558.2 mL (SD = 320.7; range = 0-2,024) and 98.7 minutes (SD = 38.6; range = 0-295), respectively. The mean cost of providing 100 mL of HM varied from $2.60 to $6.18 when maternal opportunity cost was included and from $0.95 to $1.55 when it was excluded. The cost per 100 mL of HM declined with every additional day of pumping and was most sensitive to the costs of the breast pump rental and pump kit.

CONCLUSIONS

These findings indicate that HM is reasonably inexpensive to provide and that the maternal cost of providing milk is mitigated by increasing milk output over the early NICU stay.

Improving the use of human milk during and after the NICU stay

The feeding of human milk (milk from the infant's own mother; excluding donor milk) during the newborn intensive care unit (NICU) stay reduces the risk of costly and handicapping morbidities in premature infants. The mechanisms by which human milk provides this protection are varied and synergistic, and appear to change over the course of the NICU stay. The fact that these mechanisms include specific human milk components that are not present in the milk of other mammals means that human milk from the infant's mother cannot be replaced by commercial infant or donor human milk, and the feeding of human milk should be a NICU priority. Recent evidence suggests that the impact of human milk on improving infant health outcomes and reducing the risk of prematurity-specific morbidities is linked to specific critical exposure periods in the post-birth period during which the exclusive use of human milk and the avoidance of commercial formula may be most important. Similarly, there are other periods when high doses, but not necessarily exclusive use of human milk, may be important. This article reviews the concept of "dose and exposure period" for human milk feeding in the NICU to precisely measure and benchmark the amount and timing of human milk use in the NICU. The critical exposure periods when exclusive or high doses of human milk appear to have the greatest impact on specific morbidities are reviewed. Finally, the current best practices for the use of human milk during and after the NICU stay for premature infants are summarized.

Calculating postnatal growth velocity in very low birth weight (VLBW) premature infants

OBJECTIVE

Currently, there is no standardized approach to the calculation of growth velocity (GV; g kg (-1) day(-1)) in hospitalized very low birth weight (VLBW) infants. Thus, differing methods are used to estimate GV, resulting in different medical centers and studies reporting growth results that are difficult to compare. The objective of this study was to compare actual GV calculated from infant daily weights during hospitalization in a Neonatal Intensive Care Unit (NICU) with estimated GV using two mathematical models that have been shown earlier to provide good estimated GVs in extremely low birth weight (ELBW) infants: an exponential model (EM) and a 2-Point model (2-PM).

STUDY DESIGN

Daily weights from 81 infants with birth weights (BWs) of 1000 to 1499 g were used to calculate actual GV in daily increments from two starting points: (1) birth and (2) day of life (DOL) of regaining BW. These daily GV values were then averaged over the NICU stay to yield overall NICU GV from the two starting points. We compared these actual GV with estimated GV calculated using the EM and 2-PM methods.

RESULTS

The mean absolute difference between actual and EM estimates of GV showed <1% error for 100% of infants from both starting points. The mean absolute difference between actual and 2-PM estimates showed <1% error for only 38 and 44% of infants from birth and regaining BW, respectively. The EM was unaffected by decreasing BW and increasing length of NICU stay, whereas the accuracy of the 2-PM was diminished significantly (P<0.001) by both factors.

CONCLUSION

In contrast to the 2-PM, the EM provides an extremely accurate estimate of GV in larger VLBW infants, and its accuracy is unaffected by common infant factors. The EM has now been validated for use in all VLBW infants to assess growth and provides a simple-to-use and consistent approach.

A comparison of the efficiency, efficacy, comfort, and convenience of two hospital-grade electric breast pumps for mothers of very low birthweight infants

OBJECTIVE

Many mothers of very low birthweight infants are breast pump-dependent for weeks or months and need a breast pump that is efficient, effective, comfortable, and convenient.

STUDY DESIGN

This multisite, blinded, randomized clinical trial compared the efficiency, efficacy, comfort, and convenience of the Symphony breast pump (Medela, McHenry, IL) (SBP) to the Classic breast pump (Medela) (CBP) and also compared these same outcome measures for single- and multiphase suction patterns used in the SBP. All 100 mothers initiated lactation with the CBP and were randomized to single- and multiphase suction patterns in the SBP when daily milk output was at least 350 mL/day. Protocol I included 35 mothers who compared each of three suction patterns in the SBP on two separate occasions (six observations) in the neonatal intensive care unit and used the CBP for all other pumpings. Protocol II included 65 mothers who compared single- and multiphase patterns in the SBP for 7 days and then returned to the CBP for 5 days.

RESULTS

The onset of milk ejection was quicker (P < 0.05) for the single- versus multiphase patterns in the SBP, suggesting that mothers had become conditioned to the unphysiolologic single-phase pattern in the CBP. However, all other measures of efficiency and efficacy were not significantly different, including milk output at 5-minute intervals. When asked to compare the SBP and the CBP, mothers in Protocol 1 rated the SBP as significantly more efficient, effective, comfortable, and convenient than the CBP (P < 0.05), regardless of the suction pattern in the SBP. Similarly, mothers in Protocol II rated the SBP significantly (P < 0.05) more comfortable than the CBP, regardless of the specific pattern in the SBP.

CONCLUSIONS

These findings suggest that the SBP was as efficient and effective as the CBP but was significantly more comfortable to use for pump-dependent mothers of very low birthweight infants.

Teaching Reproductive Options Through the Use of Fiction: The Cider House Rules Project

Alternative teaching strategies such as storytelling and the critical reading of literature are thought to help students develop their critical thinking, emotional intelligence, and cultural sensitivity and thereby better understand the context in which their patients live and make decisions. Such teaching methods are ideally suited for examining morally complex issues such as reproductive options. This article describes an alternative approach to teaching the complex personal, social, and moral issues surrounding the topic of reproductive options. The critical reading of the book, The Cider House Rules, provides a unique opportunity for students to obtain insight and understanding of the complex circumstances under which women and their families make reproductive decisions.

Comparison of milk output from the right and left breasts during simultaneous pumping in mothers of very low birthweight infants

PURPOSE

Milk output from the right and left breasts was compared in mothers who were pumping exclusively and had not yet fed their infants at breast.

METHODS

Thirty-five mothers of very low birthweight infants established lactation with a hospital grade, electric, dual pump, and recorded milk output separately for each breast during every pumping session from enrollment until completion of the study (mean = 19.8 days) using a standardized milk log. Milk output from each breast was also weighed during six observed milk expressions over a 2-week period during the study.

RESULTS

For the observed pumping sessions (n = 210), milk output was greater from the right breast in 65.7% of the sessions. For the milk log data (n = 3099 pumping sessions) milk output was greater from the right breast in 47.6% of the sessions, greater from the left breast in 28.0%, and equal from both breasts in 24.4% of the sessions. The mean difference in milk output between the right and left breasts was 6.6 mL (SD = 12.1) for the observed sessions, and 5.0 mL for the milk log data (SD = 10.9). The mean right-to-left breastmilk output ratio was 1.20 for the observed sessions and 1.17 for the milk log data. The right-to-left breastmilk ratios were not associated with time of day, day of pumping, total milk output, maternal handedness or the breast pump suction pattern. The right-to-left breast differences were associated with parity and breastfeeding experience, with primiparous women and first-time breastfeeders demonstrating the greatest differences.

CONCLUSIONS

These findings suggest that differences in the milk output from the right and left breasts are common, and that milk output is often greater from the right breast. The differences appear early in lactation, are not related to total milk output, and are relatively consistent throughout the day and over the first weeks of lactation.

Genetic competencies essential for health care professionals in primary care

The completion of the sequencing of the human genome in 2003 signaled the onset of the genomic era in health care. The knowledge gleaned from the Human Genome Project has led to the understanding that every health problem has a genetic component and that clinicians should include the application of genetic information in all aspects of health care. This article describes the genetic competencies essential for all health care professionals in primary care. Health care professionals should augment their current practice by obtaining a multigenerational genetic family history for each patient, assessing all patients for potentially heritable conditions, providing referrals to genetic health professionals as needed, offering genetic testing when indicated, and considering an individual's genetic makeup in the selection of medications and treatments for that person. Finally, all health care professionals ought to be prepared to address the complex personal, cultural, theological, ethical, legal, and social issues associated with genetic testing and other genetic issues commonly encountered in clinical practice.

Accuracy of a user-friendly centrifuge for measuring creamatocrits on mothers' milk in the clinical setting

The creamatocrit (CRCT), a simple, accurate, and inexpensive technique for the estimation of lipid and caloric content in mothers' milk, has been used extensively in lactation research, but has not been integrated into the routine management of clinical lactation problems such as slow weight gain in mothers' milk-fed preterm and term infants. The Creamatocrit Plus is a lightweight, noiseless centrifuge with an embedded reader that automatically calculates lipid and calories from the CRCT value, making it ideal for use in the clinical setting. This study compared intra-user and inter-user reliability, the equivalence of the CRCT values obtained with the Creamatocrit Plus to the two standard techniques for performing CRCTs: the standard laboratory centrifuge with a hematocrit reader and the standard laboratory centrifuge with digital calipers, and the predictive accuracy of the Creamatocrit Plus for estimating the lipid and caloric content in mothers' milk. CRCTs were performed using the three techniques on 36 milk specimens from 12 women. Laboratory analyses of lipid and calories were performed by investigators blinded to CRCT values. The mean absolute intra-user and inter-user differences were all <1% CRCT, and the mean CRCT measures were nearly identical for the three measurement techniques. Linear correlations between CRCT and laboratory measures for lipid (r = 0.95) and calories (r = 0.94) were very high. The authors conclude that the Creamatocrit Plus can replace cumbersome laboratory equipment for measuring CRCTs in the clinical setting.

Fetal Growth Curves: Does Classification of Weight-for-Gestational Age Predict Risk of Hypoglycemia in the Term Newborn?

Our objective was to determine whether classification of birth weight as small, average, or large for gestational age using published fetal growth curves is predictive of a term infant's risk of hypoglycemia. This prospective, descriptive study measured and plotted birth weight measurements on six published fetal growth curves to classify infant birth weight as small, average, or large for gestational age. Glucose levels were measured 2 hours after birth to determine the prevalence of hypoglycemia. The sensitivity, specificity, and positive/negative predictive values were calculated for each fetal growth curve, and odds ratios were calculated. The patients were 157 clinically stable term Caucasian and African American infants of nondiabetic mothers from a community hospital in midwestern United States. Ten of the 20 (50%) infants with hypoglycemia were classified as average for gestational age on all six published fetal growth curves. Calculated odds ratios demonstrated that none of the six published fetal growth curves significantly predicted the risk of hypoglycemia based on classification of birth weight as small, average, or large for gestational age. The risk of hypoglycemia in term infants was not accurately predicted by classification of birth weight as small, average, or large for gestational age. Clinicians should use other methods to predict which term infants are at risk for hypoglycemia.

Accuracy of methods for calculating postnatal growth velocity for extremely low birth weight infants

OBJECTIVE

No uniform method for calculating growth velocity (GV) (grams per kilogram per day) among extremely low birth weight (ELBW) infants has been reported. Because the calculation of actual GV is so labor intensive, investigators have estimated GV with varying approaches, making comparisons across studies difficult. This study compares the accuracy of 3 mathematical methods used for estimating average GV, namely, 2-point models using the difference between weights at 2 time points divided by time and weight (either birth weight [BW] or average weight), linear regression models that are normalized for either BW or average weight, and an exponential model. The accuracy of all models was compared with actual GVs calculated from daily weight measures for a group of ELBW infants.

METHODS

Actual GVs were calculated from daily weights for 83 ELBW infants admitted to the special care nursery and were compared with estimated GVs from each of the 5 models for the same infants.

RESULTS

The exponential model, using weights from 2 time points, ie, GV = [1000 x ln(Wn/W1)]/(Dn-D1), was extremely accurate, with mean absolute errors of 0.02% to 0.10%. The 2-point and linear models were highly inaccurate when BW was used in the denominator, with mean absolute errors of 50.3% to 96.4%. The 2-point and linear models were fairly accurate when average weight was used in the denominator, with mean absolute errors of 0.1% to 8.97%. Additional analyses showed that the accuracy of the 2-point and linear model estimates was affected significantly by the combination of BW, length of stay, and chronic lung disease, whereas the exponential model was not affected by these combined factors.

CONCLUSIONS

GV estimates calculated with 3 commonly used models varied widely, compared with actual GVs; however, the exponential model estimates were extremely accurate. The exponential model provides the accuracy and ease of use that are lacking in current methods applied to infant growth research.

The Rush Mothers' Milk Club: breastfeeding interventions for mothers with very-low-birth-weight infants

OBJECTIVE

To evaluate the effectiveness of an evidence-based breastfeeding program (Rush Mothers' Milk Club) for mothers and their very-low-birth-weight (VLBW) infants.

DESIGN AND SETTING

Retrospective analysis of hospital records for 207 eligible VLBW infants cared for in a 52-bed urban neonatal intensive-care unit for a 24-month period in 1997-1998.

PATIENTS/PARTICIPANTS

Entire medical records were reviewed for 207 VLBW infants whose mothers (44.9% African American, 35.7% White, 17.9% Latina) were eligible to provide own mothers' milk (OMM).

INTERVENTIONS

Standardized evidence-based interventions through the Rush Mothers' Milk Club program.

MAIN OUTCOME MEASURES

Lactation initiation rate; mean dose of OMM at 15, 30, and 60 days postbirth; mean percent of fed-hospital days equal to exclusive and some OMM feedings.

RESULTS

Lactation initiation rate was 72.9%. Mean dose of OMM over the first 15, 30, and 60 days postbirth was 81.7%, 80.1%, and 66.1%, respectively, of total volume fed. Exclusive and some OMM was received for a mean of 57.2% and 72.5%, respectively, of fed-hospital days. The outcomes for low-income African American women are the highest reported in the literature.

CONCLUSION

The Rush Mothers' Milk Club effectively achieved lactation outcomes that approach the national health objective, although the mothers had significant risk factors for initiating and sustaining lactation. The findings have important implications for clinicians, researchers, administrators, and policy makers.

Mothers performing in-home measurement of milk intake during breastfeeding of their preterm infants: maternal reactions and feeding outcomes

This study compares feeding outcomes and perceptions of mothers using in-home test weights and those who did not use test weights to manage breastfeeding of their preterm infants during the first month after hospital discharge. There were no significant differences in daily weight gain between the 2 groups during the study period. Maternal concerns cited in both groups were similar, namely, knowing how much milk infant is taking, infant gaining adequate weight, and infant getting enough milk. All women in the experimental group and two-thirds in the control group reported that in-home measurement of milk intake by test-weighing had been or would have been helpful. This prospective randomized study demonstrated that mothers of premature infants who performed in-home test-weighing procedures found the technique to be helpful and experienced no increased stress or lower achievement of breastfeeding goals when compared to mothers not performing test weighs.

Accuracy of self-reported height and weight in women: an integrative review of the literature

Height and weight are two of the most commonly used anthropometric measurements in clinical practice and research. Self-reported height and weight measurement is a simple, efficient, inexpensive, and non-invasive method of collecting data from large numbers of people. This integrative review of the published research examined the accuracy of self-reported height and weight measurements in women. Twenty-six studies examined the accuracy of self-reported height in 39,244 women. Twenty-one of the studies found that women overestimate height. Thirty-four studies reviewed the accuracy of self-reported weight in 57,172 women, and all 34 studies reported that women underestimated weight. Although mean variations between self-reported and measured values were small, a significant percentage of women in study groups had very large errors. Inaccurate measurements of both height and weight can cause significant inaccuracies in calculation of body mass index, which is used as a guide for identifying persons at risk for disease. These findings indicate that direct measurement of height and weight should be performed whenever possible for optimal measurements in clinical practice and clinically oriented research.

Mothers' milk feedings in the neonatal intensive care unit: accuracy of the creamatocrit technique

OBJECTIVE

To establish the accuracy of the creamatocrit (CRCT) for estimating lipid and calories in a heterogeneous sample of own mothers' milk (OMM) in the neonatal intensive care unit (NICU), using a hematocrit reader, rather than fine vernier calipers.

STUDY DESIGN

In this blinded study, CRCT techniques were performed on 32 fresh OMM samples (7 foremilk, 12 hindmilk, 13 composite milk) that were also analyzed for total lipid and caloric concentration.

RESULTS

Mean lipid and caloric concentrations for the OMM samples were 50.87 g/l (28.3-86.5) and 703.96 kcal/l (477.2-1183.6), respectively. Results revealed a stronger linear relationship between CRCT and total lipid (r=0.94; p<0.001) than between CRCT and caloric density (r=0.76; p<0.001).

CONCLUSION

The CRCT, using a hematocrit reader, is an accurate, inexpensive, and useful technique for estimating the lipid and caloric concentration of individual OMM samples in the NICU. The variability in lipid and calories in these 32 OMM samples underscores the utility of this technique.

Nipple shields for preterm infants: effect on milk transfer and duration of breastfeeding

This study reports breastfeeding outcomes for 34 preterm infants whose mothers used ultrathin silicone nipple shields to increase milk transfer. Mean milk transfer was compared for 2 consecutive breastfeedings without and with the nipple shield. Total duration of breastfeeding was calculated for a maximum of 365 days. Mean milk transfer was significantly greater for feedings with the nipple shield (18.4 ml vs. 3.9 ml), with all 34 infants consuming more milk with the nipple shield in place. Mean duration of nipple shield use was 32.5 days, and mean duration of breastfeeding was 169.4 days; no association between these variables was noted. The nipple shield was used for 24.3% of the total breastfeeding experience, with no significant association between the percentage of time the shield was used and total duration of breastfeeding. These findings are the first to indicate that nipple shield use increases milk intake without decreasing total duration of breastfeeding for preterm infants.

Mothers' performing creamatocrit measures in the NICU: accuracy, reactions, and cost

OBJECTIVE

To determine whether mothers of infants in the neonatal intensive-care unit could be taught to perform creamatocrits (CRCTs) accurately on own mothers' milk (OMM). These mothers' reactions to performing CRCTs also were measured.

SAMPLE

Twenty-six mothers and four advanced-practice nurses (RNs) participated in this study.

DESIGN

For Phase One of this blinded trial, mothers were taught to perform the CRCT by one of the two instructional RNs. For Phase Two, mothers and one of the two validation RNs performed CRCTs simultaneously and independently on the same OMM sample, and the mother completed a Maternal Reactions questionnaire.

RESULTS

Mothers' CRCT measures were highly accurate. The mean absolute difference between RNs' and mothers' CRCTs was 0.69%, with 50% and 84.6% of these differences, respectively, < or = 0.5% and < or = 1.0% CRCT. A strong linear correlation was noted between RNs' and mothers' CRCTs. Ninety-six percent of the mothers reported that the CRCT was easy to learn, they felt comfortable performing the procedure, and it made them feel more involved in infant care. A mean of 23.6 minutes was spent teaching the mother to perform CRCT, a figure that reflects the cost-effectiveness of the approach.

CONCLUSION

Mothers can be taught to perform CRCTs accurately and easily on their OMM. This practice exemplifies high quality, cost-effective care that maximizes maternal involvement and satisfaction.
