Insights
Frequent visits in the Neonatal Intensive Care Unit (NICU) shorten infant length of stay (LOS), potentially improving outcomes. Supporting parental involvement can reduce hospitalization costs and enhance infant and parent well-being.
Area of Science:
- Neonatal care
- Neurodevelopmental outcomes
- Healthcare economics
Background:
- Infants admitted to the Neonatal Intensive Care Unit (NICU) face elevated risks for neurodevelopmental disorders.
- The NICU environment itself can negatively impact infant neurodevelopment, beyond physical health factors.
- Optimizing infant Length of Stay (LOS) requires differentiating between medical necessity and sociodemographic influences.
Purpose of the Study:
- To identify key physical and sociodemographic factors influencing infant LOS in the NICU.
- To understand the impact of visitation frequency on infant hospital stay duration.
Main Methods:
- Utilized electronic health records for data extraction.
- Employed a backward selection regression model to analyze predictors of LOS.
Main Results:
- Physical factors like birthweight and ventilator use were primary drivers of LOS.
- Increased frequency of daily visits emerged as a significant sociodemographic predictor of shorter LOS.
Conclusions:
- Higher visitation rates correlate with shorter NICU LOS, suggesting enhanced parental engagement leads to more personalized care.
- Supporting increased parental visits can decrease hospitalization costs and improve overall infant and parent health outcomes.
Background:
Infants with past NICU admission have a significantly higher risk of developing neurodevelopmental disorders. Studies have demonstrated an iatrogenic effect of the NICU environment on neurodevelopmental outcomes, even while accounting for physical factors. It is, therefore, critical that an infant's LOS is driven by physical needs versus sociodemographic barriers.
Methods:
We leveraged electronic health records and a backward selection regression model to explore physical and sociodemographic predictors of infant LOS.
Results:
Our results demonstrated that physical predictors (birthweight and ventilator use) accounted for the majority of variance in our model but that a sociodemographic predictor, mean visits per day, was also significant.
Conclusions:
Infants who were visited more frequently experienced a shorter LOS, possibly due to increased parental involvement resulting in more individualized care and directly impacting infant stability and morbidity. By supporting visitation, we can reduce the costs of lengthy NICU hospitalizations while improving infant and parent health and well-being.
