Closing the Gap Between Recommended and Actual Human Milk Use for Fragile Infants: What Will It Take to Overcome Disparities?

A virtual dissemination framework to inform and evaluate a neonatal project ECHO (NeoECHO)

AIM

To present the development, implementation and evaluation of a theoretically grounded novel virtual dissemination evaluation (VDE) framework.

BACKGROUND

Care of intensive care unit patients requires access to the most up-to-date knowledge and best practices. To address this challenge, we present the development, implementation and evaluation of a theoretically grounded novel VDE framework. This framework is applied to a dissemination strategy, NeoECHO, in neonatal intensive care units. Evidence-based virtual education is implemented to prevent, detect and treat necrotizing enterocolitis in neonates.

DESIGN

Research Methodology: Discussion Paper-Methodology.

METHODS

The virtual dissemination evaluation framework is a sequential combination of Integration of Integrated-Promoting Action on Research Implementation in Health Services and Moore's Expanded Outcomes frameworks. The framework's conceptual determinants, virtual facilitators and implementation evaluations were operationalized in the NeoECHO dissemination strategy and evaluated for feasibility. The virtual dissemination evaluation framework was conceptually mapped, and operational activities were examined including theoretical constructs drawing on insights of nursing theorists, especially Fawcett's criteria (2005) for frameworks with practical application (significance, internal consistency, parsimony, testability and design fit). The NeoECHO strategy was evaluated for virtual dissemination evaluation adherence, operationalization and feasibility of implementation evaluation.

RESULTS

The virtual dissemination evaluation framework meets the criteria for a practical application and demonstrates feasibility for adherence and operationalization consistency. The implementation evaluation was usable in the virtual dissemination of best practices for neonatal care for necrotizing enterocolitis and healthcare providers were actively engaged in using NeoECHO as an implementation strategy.

CONCLUSION

This examination of the foundational aspects of the framework underscores the rigour required for generalization of practical application. Effective virtual dissemination of evidence-based practices to hospital units requires structured delivery and evaluation, enabling engaged healthcare providers to actualize education rapidly. The virtual dissemination evaluation frameworks' potential for narrowing the evidence-based practice gap in neonatal care showcases its wider significance and applicability.

IMPLICATIONS

Care of neonates in NICUs requires a multidisciplinary approach and necessitates access to the most up-to-date knowledge and best practices. More than traditional dissemination methods are required to bridge the implementation gap.

IMPACT

The effective use of the VDE framework can enhance the design, implementation and evaluation of knowledge dissemination, ultimately elevating neonatal care quality.

CLINICAL RELEVANCE

This paper introduces the VDE framework, a sequential combination of the iPARIHS and Moore's EO frameworks-as a methodological tool for designing, implementing and evaluating a neonatal strategy (NeoECHO) for virtual dissemination of education in NICUs.

Proteomics Profiling of Stool Samples from Preterm Neonates with SWATH/DIA Mass Spectrometry for Predicting Necrotizing Enterocolitis

Necrotizing enterocolitis (NEC) is a life-threatening condition for premature infants in neonatal intensive care units. Finding indicators that can predict NEC development before symptoms appear would provide more time to apply targeted interventions. In this study, stools from 132 very-low-birth-weight (VLBW) infants were collected daily in the context of a multi-center prospective study aimed at investigating the potential of fecal biomarkers for NEC prediction using proteomics technology. Eight of the VLBW infants received a stage-3 NEC diagnosis. Stools collected from the NEC infants up to 10 days before their diagnosis were available for seven of them. Their samples were matched with those from seven pairs of non-NEC controls. The samples were processed for liquid chromatography-tandem mass spectrometry analysis using SWATH/DIA acquisition and cross-compatible proteomic software to perform label-free quantification. ROC curve and principal component analyses were used to explore discriminating information and to evaluate candidate protein markers. A series of 36 proteins showed the most efficient capacity with a signature that predicted all seven NEC infants at least a week in advance. Overall, our study demonstrates that multiplexed proteomic signature detection constitutes a promising approach for the early detection of NEC development in premature infants.

Lipocalin-2 and calprotectin as stool biomarkers for predicting necrotizing enterocolitis in premature neonates

BACKGROUND

Necrotizing enterocolitis (NEC) is a major challenge for premature infants in neonatal intensive care units and efforts toward the search for indicators that could be used to predict the development of the disease have given limited results until now.

METHODS

In this study, stools from 132 very low birth weight infants were collected daily in the context of a multi-center prospective study aimed at investigating the potential of fecal biomarkers for NEC prediction. Eight infants (~6%) received a stage 3 NEC diagnosis. Their stools collected up to 10 days before diagnosis were included and matched with 14 non-NEC controls and tested by ELISA for the quantitation of eight biomarkers.

RESULTS

Biomarkers were evaluated in all available stool samples leading to the identification of lipocalin-2 and calprotectin as the two most reliable predicting markers over the 10-day period prior to NEC development. Pooling the data for each infant confirmed the significance of lipocalin-2 and calprotectin, individually and in combination 1 week in advance of the NEC clinical diagnosis.

CONCLUSIONS

The lipocalin-2 and calprotectin tandem represents a significant biomarker signature for predicting NEC development. Although not yet fulfilling the "perfect biomarker" criteria, it represents a first step toward it.

IMPACT

Stool biomarkers can be used to predict NEC development in very low birth weight infants more than a week before the diagnosis. LCN2 was identified as a new robust biomarker for predicting NEC development, which used in conjunction with CALPRO, allows the identification of more than half of the cases that will develop NEC in very low birth weight infants. Combining more stool markers with the LCN2/CALPRO tandem such as PGE2 can further improve the algorithm for the prediction of NEC development.

An Interdisciplinary Approach to Reducing NEC While Optimizing Growth: A 20-Year Journey

BACKGROUND

Necrotizing enterocolitis (NEC) and postnatal growth restriction are significant clinical dilemmas that contribute to short- and long-term morbidities for the most premature infants.

PURPOSE

After a rise in NEC rates in a regional neonatal intensive care unit (NICU), improvement practices were implemented by an interdisciplinary quality improvement (QI) work group whose focus was initially on nutrition and growth. QI work was refocused to address both NEC and growth concurrently.

METHODS

Through various QI initiatives and with evolving understanding of NEC and nutrition, the work group identified and implemented multiple practices changes over 2-decade time span. A standardized tool was used to review each case of NEC and outcomes were continually tracked to guide QI initiatives.

LOCAL FINDINGS

Focused QI work contributed to a significant reduction in NEC rates from 16.2% in 2007 to 0% in 2018 for inborn infants. Exclusive human milk diet was a critical part of the success. Postnatal growth outcomes initially declined after initial NEC improvement work. Improvement work that focused jointly on NEC and nutrition resulted in improved growth outcomes without impacting NEC.

IMPLICATIONS FOR PRACTICE

Use of historical perspective along with evolving scientific understanding can guide local improvement initiatives. Work must continue to optimize lactation during NICU hospitalization. More research is needed to determine impact of care practices on gastrointestinal inflammation including medication osmolality, probiotics, and noninvasive respiratory support.

Quality Improvement to Increase Breastfeeding in Preterm Infants: Systematic Review and Meta-Analysis

Background and Objective: Due to its numerous health benefits, breast milk (BM) is recommended for preterm infants. Despite such recommendations, the rates of breastfeeding in preterm infants are lower than that in term infants. Quality improvement (QI) bundles increase breastfeeding in preterm infants, but their replication in neonatal intensive care units has had inconsistent outcomes. Methods: We used the Population or Problem, Intervention, Comparison, and Outcomes (PICO) framework to develop our search strategy, and searched MEDLINE, Embase, and the Cochrane Library from inception through January 15, 2021. Studies describing any active QI intervention to increase BM use in preterm infants were included. The primary outcome measure was the rate of any breastfeeding or exclusive mother's own milk (MOM) at discharge or during hospitalization. Results: Sixteen studies were eligible for inclusion and showed an acceptable risk of bias, and included 1 interrupted time series, study 3 controlled before-and-after studies, and 12 uncontrolled before-and-after studies; of these, 3 studies were excluded due to insufficient dichotomous data, 13 were included in the meta-analysis. In the meta-analysis, the rate of any breastfeeding was significantly improved at discharge and during hospitalization after QI [risk ratio (RR) = 1.23, 95% confidence interval (CI): 1.14-1.32, P < 0.00001 and RR = 1.89, 95% CI: 1.09-3.29, P = 0.02, respectively]. The rate of exclusive MOM after QI was also significantly increased at discharge (RR = 1.51, 95% CI: 1.04-2.18, P = 0.03), but not during hospitalization (RR = 1.53, 95% CI: 0.78-2.98, P = 0.22). However, after sensitivity analysis, the comprehensive results still suggested that QI could significantly improve the rate of exclusive MOM during hospitalization (RR = 1.21, 95% CI: 1.08-1.35, P = 0.001). Funnel plots and Egger's test indicated publication bias in the rate of any BF at discharge. We corrected publication bias by trim and fill analysis, and corrected RR to 1.272, 95% CI: (1.175, 1.369), which was consistent with the results of the initial model. Conclusions: A QI bundle appears to be effective for promoting BM use in preterm infants at discharge or during hospitalization.

The Effect of Donor Human Milk Fortification on The Adhesion of Probiotics In Vitro

Preterm delivery complications are the primary cause of death among children under the age of five. Preventive strategies include the use of pasteurized donor human milk (DHM), its fortification with human milk fortifiers (protein supplements), and supplementation with probiotics. Our aim was to examine the impact of DHM and fortified DHM (FDHM) on the mucus adhesion properties of two widely used probiotics. The study covered two forms of human milk fortifier, liquid and powdered, with or without probiotics and storage at 4 °C for 24 h. To test the adhesion properties of the probiotic strains, DHM+probiotics and FDHM+probiotics were prepared and added to immobilized mucus isolated from the stool of healthy Finnish infants. The probiotic adhesion was then measured by liquid scintillation. Our results suggest that addition of liquid or powdered human milk fortifier in donor human milk had no impact on probiotic adhesion. In addition, given the increased adhesion of probiotics suspended in buffer, other matrices should be further studied. These factors need to be considered when designing future intervention strategies using probiotics in preterm infants.
