Improving Admission Temperature in Infants ≥34 Weeks' Gestation: A Quality Improvement Initiative.

Background: NICU admission for hypothermia is a problem worldwide, with associated morbidity, mortality, and financial costs. Many interventions have been studied for smaller infants, but there has been little focus on infants born ≥34 weeks' gestational age (GA), though most deliveries occur at this gestation. Our primary aim was to improve the proportion of infants ≥34 weeks' GA with normal NICU admission temperature. Secondary outcomes included improvement of the proportion of normal first temperature in all infants ≥34 weeks' GA, independent of NICU admission, and improvement of predefined outcome measures.

Methods: We completed a root cause analysis, using fishbone and process mapping to determine what factors were contributing to hypothermia. A series of changes were trialed using plan-do-study-act cycles to develop a standard operating procedure, covering both vaginal and cesarean section births. Outcome measures were analyzed using a P-chart as well as traditional statistical tests.

Results: We successfully increased the proportion of infants ≥34 weeks' GA with normothermia on NICU admission from 62% to 80% without increasing hyperthermia. In addition, the interventions improved the proportion of delivery room normothermia in all infants born ≥34 weeks' GA and were associated with a decreased need for intravenous therapy for hypoglycemia and the incidence of metabolic acidosis.

Conclusions: This quality improvement initiative was successful at improving our institution's rates of normal infant temperature. The methodology used can be applied to other similar centers to improve this common problem.
