Comparison of forehead infrared thermometry with axillary digital thermometry in neonates

Fluctuations in core body temperature beyond a narrow range are of concern as they indicate changed homeostasis. Thermoregulation remains a key aspect of neonatal care. New ‘non touch’ method of measuring temperature may reduce infection rate and discomfort of neonates. Body temperature of neonates admitted in Neonatal Intensive Care Unit was measured using axillary digital thermometer and a handheld infrared non touch thermometer. The two methods did not agree well (mean difference = −0.5, 95% limits of agreement: [−2.3, 1.2]). The agreement was similar with a negligible difference when patients in open care warmers were excluded (mean difference = −0.6, 95% limits of agreement: [−2.3, 1.1]). As the accuracy is unsatisfactory, the said technology needs further improvement before it can be adapted for routine patient care.
