Abstract:
We evaluated an infrared tympanic thermometer (Genius 3000A) by comparing it with parallel measurements with an electronic rectal thermometer (Philips HP 5316) on 121 patients admitted to a geriatric department. Rectal temperature was on average 0.14 degree C +/- (ISD) above the ear temperature. 95% of the differences are within the interval from -1.18 degrees C to 1.46 degrees C. The coefficient of determination was only 0.30. The tympanic thermometer, Genius 3000A, cannot be recommended for daily use on a geriatric ward.
