Rectal Versus Axillary Temperatures: Is There a Significant Difference in Infants Less Than 1 Year of Age?

There are identified gaps regarding the accuracy of axillary temperatures as a means of predicting core temperatures in infants and children. This article discusses the relationship between rectal and axillary temperatures in infants less than 1 year of age. This quality improvement project evaluated 425 paired temperature measurements in 86 infants admitted to an inpatient pediatric unit over a 2-month period. A correlation analysis showed statistically significant differences between the two measurements. The results of this project promoted the development of a standard of care for temperature measurement at the project facility.
