Background:
Several continuous wireless thermometers have been developed as an alternative to invasive continuous thermometers, with limited studies performed. TempTraq® patches are non-invasive thermometers applied to the axilla that continuously monitor body temperature and transmit readings wirelessly. We aimed to evaluate the accuracy and tolerability of TempTraq® patches in children.
Methods:
We conducted a method-comparison study over one year comparing TempTraq® to tympanic thermometer readings in hospital inpatients aged 1 to 17 years. TempTraq® patch readings, tympanic thermometer readings, and guardian and participant satisfaction were assessed.
Results:
Of 100 enrolled participants, 74 were included for analysis as they had worn the patch for minimum 6 h. The 810 paired TempTraq® axillary and tympanic temperature readings showed significant agreement between the two methods with mean difference of -0.39 °C (1.07, 95% limits of agreement -2.49 °C to 1.71 °C). TempTraq® identified febrile events on average 95 minutes earlier than intermittent temperature monitoring. TempTraq® had high satisfaction ratings.
Conclusions:
TempTraq® patch readings are comparable to tympanic temperature readings and acceptable to paediatric patients and guardians. By continuously monitoring temperature, wireless thermometers may improve response times to clinical events and decrease nursing workload of obtaining manual measurements, resulting in cost savings and improvement in patient outcomes.
Impact:
Thermometers currently used in routine clinical settings to measure patients' temperature have significant drawbacks, including patient disturbance, poor accuracy and the need for dedicated time by the nursing team. Continuous wireless monitoring does not require regular measurements by the nursing team and could prompt faster clinical response to sudden changes in temperature. This study with a large paediatric population addressed the performance of TempTraq patch® wireless continuous thermometers compared to tympanic thermometers in paediatric patients. TempTraq® patch readings are comparable to tympanic temperature readings, removing the need for manual measurements, and received positive feedback from patients and guardians.

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,...
