Re-evaluation of the tympanic thermometer in the emergency department

Area of Science:

• Pediatric Medicine
• Medical Device Technology

Background:

• Accurate temperature measurement is crucial in pediatric care.
• Infrared tympanic thermometers are widely used for their convenience.

Purpose of the Study:

• To re-evaluate the accuracy of a portable infrared tympanic thermometer in pediatric patients.
• To compare tympanic temperatures with rectal temperatures.

Main Methods:

• A portable infrared tympanic thermometer was used to measure temperatures in 79 pediatric patients in an emergency department.
• Temperatures were recorded sequentially using both an electronic digital thermometer and the infrared tympanic thermometer set to core equivalency.
• Rectal temperatures served as the reference standard.

Main Results:

• The overall correlation between rectal and tympanic temperatures was high (0.93, P < .001).
• For children older than 3 months, the tympanic thermometer demonstrated high sensitivity (100%) and specificity (100%) for detecting fever.
• The correlation was weaker in infants 3 months of age and younger.

Conclusions:

• The infrared tympanic thermometer is a reliable tool for fever detection in pediatric patients over 3 months of age.
• Results for infants under 3 months require further investigation due to inconclusive data.
