ABSTRACT
Infrared tympanic thermometers (ITT) have many documented benefits, including speed, ease of use, and noninvasiveness, to support their use in emergency departments (ED) and intensive care units (ICU). However, concerns have been raised about the accuracy of temperatures reported by ITT. This study was conducted to evaluate the accuracy of 3 brands of ITT, compared to rectal and pulmonary artery thermometers, in ED and ICU settings. Results indicated adequate specificity for all 3 ITT in ED (range = 0.9242 to 1.0000) and ICU (range = 0.9737 to 1.0000), but unacceptable sensitivity in ED (range = 0.5455 to 0.8000) and ICU (range = 0.0000). Further analyses indicated highly variable ITT-reported temperatures. In ED, ITT temperatures were, on average, 0.3684 degree C lower, and could be expected to vary by more than 2 degrees C from the actual temperature as reported by rectal thermometer. In ICU, the average reported temperature was similar to the actual pulmonary artery temperature (0.0259 degree C lower), but again could vary by more than 2 degrees C. Recommendations for nursing and education are discussed.
