Validity of Wrist and Forehead Temperature in Temperature Screening in the General Population During the Outbreak of 2019 Novel Coronavirus: a prospective real-world study

AimsTemperature screening is important in the population during the outbreak of 2019 Novel Coronavirus (COVID-19). This study aimed to compare the accuracy and precision of wrist and forehead temperature with tympanic temperature under different circumstances. MethodsWe performed a prospective observational study in a real-life population. We consecutively collected wrist and forehead temperatures in Celsius ({degrees}C) using a non-contact infrared thermometer (NCIT). We also measured the tympanic temperature using a tympanic thermometers (IRTT) and defined fever as a tympanic temperature [≥]37.3{degrees}C. ResultsWe enrolled a total of 528 participants including 261 indoor and 267 outdoor participants. We divided outdoor participants into four types according to their means of transportation to the hospital as walk, bicycle, electric vehicle, car, and inside the car. Under different circumstance, the mean difference ranged from -1.72 to -0.56{degrees}C in different groups for the forehead measurements, and -0.96 to -0.61{degrees}C for the wrist measurements. Both measurements had high fever screening abilities in inpatients (wrist: AUC 0.790; 95% CI: 0.725-0.854, P <0.001; forehead: AUC 0.816; 95% CI: 0.757-0.876, P <0.001). The cut-off value of wrist measurement for detecting tympanic temperature [≥]37.3{degrees}C was 36.2{degrees}C with a 86.4% sensitivity and a 67.0% specificity, and the best threshold of forehead measurement was also 36.2{degrees}C with a 93.2% sensitivity and a 60.0% specificity. ConclusionsWrist measurement is more stable than forehead measurement under different circumstance. Both measurements have great fever screening abilities for indoor patients. The cut-off value of both measurements was 36.2{degrees}C. (ClinicalTrials.gov number: NCT04274621)

Risk Factors of Bloodstream Infection in ICU / 中华医院感染学杂志

OBJECTIVE To investigate risk factors of bloodstream infection in ICU.METHODS From May 2007 to Aug 2007,the operation of central venous catheter and the medical attendance of 24 cases with bloodstream infection were retrospectively analyzed.RESULTS Fifteen cases with infection(62.5%) were found in 7 days;ESBLs-producing Klebsiella pneumoniae,Enterobacter,and Acinetobacter baumannii were the major pathogens.The major risk factors included severe underlying diseases,endovascular catheter operation and incorrect asepsis barrier.CONCLUSIONS The patients are severe in ICU.In order to control and prevent infection in ICU,effective measures should be taken,including taking strict aseptic treatment in central venous catheter and the medical attendance of catheters,and strengthen hygiene administration.
