lack of agreement of tympanic membrane temperature assessments with conventional methods in a private practice setting
Pediatrics, 1992Co-Authors: Gary L Freed, J K FraleyAbstract:An infrared tympanic membrane Thermometer (FIRST temp) said to approximate core temperature accurately is being marketed as a noninvasive, quick, and easy-to-use clinical instrument. The determination of tympanic membrane temperatures by this device was compared with the determination of oral, rectal, or axillary temperatures by a conventional Glass Thermometer. Subjects were patients of a pediatric group practice in Houston, Texas. FIRST temp and conventional temperature determinations on individual patients were completed within 5 minutes of each other. The presence or absence of otitis media was noted by the examining physician. Agreement between the two methods of temperature determination was assessed by calculating limits of agreement within which 95% (+/- 2 standard deviations) of individual differences would fall. The location of conventional Thermometer (oral, rectal, axillary), time interval between the two separate measures, and the presence or absence of otitis media were entered into a multiple regression analysis to determine whether these factors influenced the observed differences between the two methods. A total of 144 patients were enrolled in the study; oral comparisons were obtained in 92 (57%) patients, rectal in 35 (24%), and axillary in 29 (19%). The upper and lower limits of agreement between temperature methods were 1.12 degrees C and 0.89 degrees C and the mean difference was -0.12 degrees C. Regression analysis revealed that only the site of conventional Thermometer location (oral, rectal, axillary) was a significant predictor of FIRST temp/conventional differences. Each site had a range of agreement greater than 1.65% degrees C; axillary temperatures had the greatest range (-0.94 degree C to +1.30 degrees C.(ABSTRACT TRUNCATED AT 250 WORDS)

precision of a new Thermometer for rapid rectal temperature measurement in neonates
American Journal of Perinatology, 2001Co-Authors: Shaul Dollberg, Sigalit Lahav, Francis B MimouniAbstract:The objective of this article is to evaluate the accuracy and reproducibility of a Penguin electronic Thermometer compared with a mercury-in-Glass Thermometer for rectal thermometry in newborns. The mercury-in-Glass Thermometer is considered the "gold-standard" for rectal thermometry. Unfortunately, accurate measurement with a mercury-in-Glass Thermometer requires at least 4 minutes. Rectal temperature was obtained in 224 term and near-term infants using a mercury-in-Glass and a Penguin Thermometers. Paired t-test was used to test the difference between the means, and F-test was used to test the difference between the variances of the two instruments. One hundred and sixty-one of the temperature measurements (72%) taken with the Penguin Thermometer were within +/-0.2 degrees C and 208 (93%) within +/-0.5 degrees C from the measurements made with the mercury-in-Glass Thermometer. The differences in means and in variances were not significantly different between the instruments. The Penguin Thermometer is an accurate and reproducible tool for measuring rectal temperature in term and near-term infants compared with the mercury-in-Glass Thermometer.

measurement of body temperature in adult patients comparative study of accuracy reliability and validity of different devices
International Journal of Nursing Studies, 2011Co-Authors: J Rubiarubia, A Sierra, A. Arias, A AguirrejaimeAbstract:Abstract Background and aims We compared a range of alternative devices with core body temperature measured at the pulmonary artery to identify the most valid and reliable instrument for measuring temperature in routine conditions in health services. Methods 201 patients from the intensive care unit of the Candelaria University Hospital, Canary Islands, admitted to hospital between April 2006 and July 2007. All patients (or their families) gave informed consent. Readings from gallium-in-Glass, reactive strip and digital in axilla, infra-red ear and frontal Thermometers were compared with the pulmonary artery core temperature simultaneously. External factors suspected of having an influence on the differences were explored. The cut-off point readings for each Thermometer were fixed for the maximum negative predictive value in comparison with the core temperature. The validity, reliability, accuracy, external influence, the waste they generated, ease of use, speed, durability, security, comfort and cost of each Thermometer was evaluated. An ad hoc overall valuation score was obtained from these parameters for each instrument. Results For an error of ±0.2°C and concordance with respect to fever, the gallium-in-Glass Thermometer gave the best results. The largest area under the receiver operating characteristic (ROC) curve is obtained by the digital axillar Thermometer with probe (0.988±0.007). The minimum difference between readings was given by the infrared ear Thermometer, in comparison with the core temperature (−0.1±0.3°C). Age, weight, level of conscience, male sex, environmental temperature and vaso-constrictor medication increases the difference in the readings and fever treatment reduces it, although this is not the same for all Thermometers. The compact digital axillar Thermometer and the digital Thermometer with probe obtained the highest overall valuation score. Conclusion If we only evaluate the aspects of validity, reliability, accuracy and external influence, the best Thermometer would be the gallium-in-Glass after 12min. The gallium-in-Glass Thermometer is less accurate after only 5min in comparison with the reading taken after being placed for 12min. If we add the evaluation of waste production, ease-of-use, speed, durability, security, patient comfort and costs, the Thermometers that obtain the highest score are the compact digital and digital with probe in right axilla.
