Insights
Tympanic infrared thermometry is not sensitive enough for screening fever in children. However, it may help confirm fever when suspected by touch in primary care settings.
Area of Science:
- Pediatrics
- Primary Care Medicine
- Medical Devices
Background:
- Tympanic thermometry offers convenience in primary care.
- Limited data exists comparing tympanic thermometry with traditional methods.
- Accurate fever detection is crucial in pediatric primary care.
Purpose of the Study:
- To compare the accuracy of tympanic infrared thermometry against axillary mercury thermometry in preschool children.
- To evaluate tympanic thermometry's utility as a screening and diagnostic tool for fever in primary care.
Main Methods:
- A study involving 94 preschool children with acute cough in UK primary care.
- Comparison of tympanic infrared and axillary mercury thermometers.
- Analysis of agreement, sensitivity, and specificity.
Main Results:
- Tympanic infrared thermometry demonstrated poor agreement and low sensitivity.
- High specificity was observed for tympanic infrared thermometry.
- The device was found to be too insensitive for fever screening.
Conclusions:
- Tympanic infrared thermometry is unsuitable as a standalone fever screening tool for children.
- It may serve as a 'rule in' test for fever when clinical suspicion is already present.
- Further research on accurate pediatric thermometry in primary care is warranted.
Abstract:
The use of tympanic thermometry is attractive in primary care, but a recent systematic review highlighted the paucity of data comparing tympanic thermometry with conventional methods. We report a study of 94 preschool children presenting to primary care in the United Kingdom (UK) with acute cough in whom tympanic infrared and axillary mercury thermometry are compared. Infrared thermometry showed poor agreement, poor sensitivity and high specificity. Infrared thermometry is too insensitive to be used as a screening test for fever, but when fever is already suspected, for example by touch, it may be useful as a 'rule in' test.

Equipments Used to Measure Body Temperature
Glass-bulb Thermometer:
Glass-bulb thermometers are hollow glass tubes with a bulb tip containing liquid such as ethanol or mercury. Historically, glass bulb mercury thermometers were the standard device to measure body temperature. Today, mercury thermometers are prohibited in many countries due to the hazardous effects of mercury and the risk of exposure if the glass bulb breaks. In general,...
Temperature Measurement Sites
Oral: When assessing oral temperature, the thermometer tip should be placed under the tongue in the posterior sublingual pocket. It offers accurate readings and can be...
Assessing Body Temperature - Temporal Artery
Step 1: Perform hand hygiene and don a fresh pair of gloves to prevent cross-infection and ensure patient safety.
Step 2: Explain the procedure to the patient to establish trust. Clear communication establishes trust with the patient, ensures they understand what to expect, promotes cooperation, and enhances comfort during the procedure.
Step 3: Assess the patient's forehead...
Assessing Body Temperature - Tympanic membrane
Step 1: Begin by practicing good hand hygiene to prevent the transmission of microorganisms.
Step 2: Turn on the thermometer and wait until the ready sign appears on the screen to ensure accurate measurement.
Step 3: Slide the probe cover in place to prevent cross-contamination.
Step 4: Instruct the patient to tilt their head to the side for comfort and check for cerumen...
