Infrared tympanic thermometry. Experience and training does not improve the quality of measurement results

Nurses, with and without training in the use of infrared tympanic thermometry, performed measurement sequences on patients. One rectal and two repeated measurements with each of two types of equipment for infrared tympanic thermometry (Genius, Core Check) were used in each sequence. Rectal measurements showed temperatures significantly higher than infrared tympanic thermometry, but there were variations (Genius 0.3 +/- 0.58 (SD) degree C, Core Check 0.5 +/- 0.42 (SD) degree C). The sensitivity of infrared tympanic thermometry for fever, as defined by rectal measurements, was 36% for Genius and 21% for Core Check. The quality of the measurements was not improved by training. Our results indicate that infrared tympanic thermometry should be used with caution when screening for fever in hospitals.
