Two Temperature

Background: Temperature screening checkpoints have become widely distributed during the COVID-19 pandemic, using various contactless methods of temperature measurement, including wrist and forehead measurement. Aim: In this study we aim to investigate the sensitivity and specificity of these two temperature measurement methods – wrist and forehead – compared with the standards of sublingual or axillary measurement. We also aim to investigate the influence of age, gender, device brand and diurnal effect on the temperature reading. Methods: Participants were randomly assigned to one of two groups, each group using a different temperature measurement device. All participants had their forehead and wrist temperature measured, and this was compared to their axillary or sublingual readings. Results: The area under the curve for wrist measurement was 0.49 (95% CI 0.34 and 0.64), p>0.05, with a sensitivity of 46.2% and specificity of 53.3%, while the area under the curve for forehead measurement was 0.70 (95% CI 0.51, 0.89), p<0.05, with a sensitivity of 23.1% and specificity of 76.9%, PPV 1.59% and NPV 97.7%. Conclusion: Wrist and forehead temperature measurement is not accurate in detecting fever during the ongoing COVID-19 pandemic. Although forehead measurement is also not an ideal method, it nevertheless appears more consistent than wrist measurement.

In industrial technological processes associated with the heating of the processed material by microwave radiation, it is necessary to measure the temperatures of objects. Methods for measuring temperatures in the fields of technology using microwave heating systems are considered. The main possibilities, disadvantages and limitations of the used contact and non-contact (optical) measurement methods are determined. The requirements for temperature measurement systems under conditions of exposure to strong electromagnetic fields are listed. The possibilities of the spectral pyrometry method are especially noted.

Introduction: The aim of this survey was to investigate the current knowledge, attitudes, and practices of febrile children’s caregivers about fever, antipyretic usage, and temperature measurement methods in a tertiary care hospital. Methodology: A 41-item questionnaire was administered to a convenience sample of febrile children’s caregivers in face-to-face interviews by two research assistants from January 2012 through June 2012 in an urban region of Turkey. Results: A total of 1,032 caregivers completed the interview. Approximately one-third of caregivers considered a temperature of less than 37.8°C (100°F) to be a fever, and 13% of all respondents would give antipyretics for a body temperature ≤ 37.8°C. Furthermore, 76% of parents would wake their children from sleep to administer antipyretics. Although a high proportion (89.5%) of respondents believed that fever had harmful effects, 10.5% considered fever to be beneficial. Alternating use of acetaminophen and ibuprofen (44%) and giving antipyretics routinely (71%) before and after immunizations were common parental practices and generally advised by pediatricians. Parents with higher levels of education were more likely to consider fever to be beneficial and to treat fever with antipyretics, and less likely to seek medical attention for mild fever. Most caregivers stated that they were unsure about the right site (90%) and thermometer type (95%) for temperature measurement. Conclusions: Persistent fever anxiety and excessive antipyretic usage may be heightened by the lack of knowledge regarding accurate temperature measurement methods with digital thermometers in our population. Parental education may positively affect the approach to fever and antipyretic usage.
