Effectiveness of a measure program to prevent admission hypothermia in very low-birth weight preterm infants.

Objective: To evaluate the effectiveness of a thermoregulation bundle for preventing admission hypothermia in very low-birth weight preterm infants.

Methods: Interventional study with retrospective evaluation of data undertaken in a tertiary neonatal unit including all very low-birth weight preterm infants (<1500g) born at and admitted to the unit. Two periods were compared: before intervention (PI; 01/01/2012 to 02/28/2014_ and after intervention (PII; 04/01/2014 to 11/30/2016).
