Clinical Trial Summary

The purpose of this study is to explore the impact of bundling nursing care activities on the overall health of Very Low Birthweight (VLBW) preterm infants who receive bundled care in a Level IV Neonatal Intensive Care Unit (NICU). The study will evaluate differences in infant health when diaper changes occur at 3- versus 6-hours during 3-hour bundled care. Differences in infant skin health between 3- and 6-hour bundled care diapering at two sites (buttocks and chest) will also be evaluated.

Description:

Preterm infants' growth and developmental outcomes vary with illness severity and degree of neurological insult and unpredictable variations in outcomes exist even among healthy preterm infants. The variations in preterm infants' outcomes have led to the supposition that the neonatal intensive care unit (NICU) environment may negatively impact the health and development of these infants and significant research has been devoted to examination of light, noise, and caregiving interventions. Consequently, many NICUs have implemented neuroprotective strategies to reduce over simulation, promote sleep and facilitate brain development in high-risk infants including the grouping of care activities around a single caregiving event described as "clustering" or "bundling care". Yet, the number and type of caregiving activities that are included in bundled care and the timeframe between bundled care events has not been systematically studied. The inclusion and exclusion of certain care activities in any individual care event is often dictated by the infant's treatment plan or needs, but some activities like diapering may be optional. Understanding the impact of when to include optional, yet stress provoking interventions, will allow us to minimize overall environmental stress in hospitalized very low birthweight (VLBW) infants. Therefore, given the lack of data around bundled care, the investigators aim to explore through a randomized controlled design the impact of bundling diaper care activities on overall health of VLBW preterm infants. The investigators will include a focus on skin health because it is important to understand the benefits of decreased infant stress and any potential skin health trade-offs associated with longer versus shorter time between diapering care. Findings from this study will allow us to better understand the relationship between neonatal skin health while providing developmentally appropriate bundled care.

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Mean Heart Rate by Group	Heart rate instability was defined as having a mean heart rate value during a bundled care event that was =1 standard deviation above or below the mean heart rate value during the 90 minutes before the event started. In addition, clinically meaningful parameters were added to indicate exceptions to this definition. For HR, mean values = one standard deviation below the mean was categorized as physiologically unstable only if the mean value was < 100. Based on these criteria, each observation was categorized as physiologically unstable or not.	During hospitalization, approximately four weeks
Secondary	Estimates of Infant Buttock Transepidermal Water Loss (TEWL) by Group	TEWL was measured at the beginning of each bundled care event using the DermaLab® TEWL probe (Cortex Technology, Hadsund, Denmark). Transepidermal water loss is the process of water moving through the layers of the skin and evaporating.; Linear mixed models (LMM) were used to examine group differences in TEWL. Outcomes in these models consisted of within-subject change over time in skin TEWL of the buttock. In the model, TEWL was regressed on diaper change group and the number of days since study initiation. TEWL estimates and confidence intervals are reported by group across all bundled care observations.	During hospitalization, approximately four weeks
Secondary	Microbiota Diversity of the Skin at Both the Buttocks and Chest Sites and Stool by Group	The Shannon Diversity index measures the alpha diversity of a bacterial sample. Function of richness and evenness of 16S rRNA gene amplicon sequence variants (i.e., proxy for prokaryote species-like groupings) within each sample. A higher Shannon diversity means that a sample had a combination of a higher number of species of archaea and bacteria, and/or a more even relative abundance of those species within a sample.	During hospitalization, approximately four weeks
