Insights
A new prevention bundle significantly reduced hypothermia in very low birth weight (VLBW) infants. This intervention also decreased the incidence of intraventricular hemorrhage (IVH) in these vulnerable newborns.
Area of Science:
- Neonatal Intensive Care
- Pediatric Quality Improvement
- Perinatal Medicine
Background:
- Hypothermia is a common complication in very low birth weight (VLBW) infants post-birth.
- Existing medical resources do not fully prevent neonatal hypothermia.
- Effective interventions are needed to improve outcomes for VLBW infants.
Purpose of the Study:
- To design a standardized prevention bundle to decrease hypothermia in infants.
- To evaluate the efficacy of this prevention bundle in VLBW infants.
- To assess the impact of the bundle on short-term outcomes for VLBW infants.
Main Methods:
- A quality improvement project involving VLBW infants in a neonatal intensive care unit.
- Classification of infants into pre-intervention and post-intervention groups.
- Analysis of hypothermia causes, development of a prevention bundle, and comparison of outcomes before and after implementation.
Main Results:
- Significant reduction in hypothermia incidence in the delivery room (45.9% to 8.6%) and on admission (59.5% to 15.5%).
- Marked decrease in intraventricular hemorrhage (IVH) rates from 21.6% to 5.2% (P = 0.015).
- Overall improvement in short-term outcomes for VLBW infants post-bundle implementation.
Conclusions:
- The standardized prevention bundle is effective in preventing hypothermia in VLBW infants.
- The bundle led to a significant reduction in IVH rates.
- This simple, low-cost, and replicable tool can improve VLBW infant outcomes.
Introduction:
In very low birth weight (VLBW) infants, hypothermia immediately following birth is common even in countries rich in medical resources. The purpose of this study is to design a standard prevention bundle that decreases the rate of hypothermia among infants after birth and to investigate efficacy of the bundle and short-term outcomes for VLBW infants.
Methods:
This quality improvement project was conducted from February 2017 to July 2018 on all VLBW preterm infants admitted at a single referral level III neonatal intensive care unit. The infants were classified into the pre-intervention (February to September 2017) and post-intervention (October 2017 to July 2018) groups according to the time periods when they were recruited. During the pre-intervention period, we analyzed the primary causes of hypothermia, developed solutions corresponding to each cause, integrated all solutions into a prevention bundle, and applied the bundle during the post-intervention period. Afterwards, the incidence of neonatal hypothermia and short-term outcomes, such as intraventricular hemorrhage (IVH), acidosis, and shock requiring inotropic agents, in each group were compared.
Results:
A total of 95 VLBW infants were enrolled in the study, including 37 pre-intervention, and 58 post-intervention cases. The incidence of hypothermia in preterm infants decreased significantly upon the implementation of our prevention bundle, both in the delivery room (from 45.9% to 8.6%) and on admission (59.5% to 15.5%). In addition, the short-term outcomes of VLBW infants improved significantly, especially with the decreased incidence of IVH (from 21.6% to 5.2%, P = 0.015).
Conclusions:
Our standardized prevention bundle for preventing hypothermia in VLBW infants is effective and decreased the IVH rate in VLBW infants. We strongly believe that this prevention bundle is a simple, low-cost, replicable, and effective tool that hospitals can adopt to improve VLBW infant outcomes.
