Accuracy of parents in measuring body temperature with a tympanic thermometer
Bibliographic record
Abstract
BACKGROUND: It is now common for parents to measure tympanic temperatures in children. The objective of this study was to assess the diagnostic accuracy of these measurements. METHODS: Parents and then nurses measured the temperature of 60 children with a tympanic thermometer designed for home use (home thermometer). The reference standard was a temperature measured by a nurse with a model of tympanic thermometer commonly used in hospitals (hospital thermometer). A difference of >or= 0.5 degrees C was considered clinically significant. A fever was defined as a temperature >or= 38.5 degrees C. RESULTS: The mean absolute difference between the readings done by the parent and the nurse with the home thermometer was 0.44 +/- 0.61 degrees C, and 33% of the readings differed by >or= 0.5 degrees C. The mean absolute difference between the readings done by the parent with the home thermometer and the nurse with the hospital thermometer was 0.51 +/- 0.63 degrees C, and 72 % of the readings differed by >or= 0.5 degrees C. Using the home thermometer, parents detected fever with a sensitivity of 76% (95% CI 50-93%), a specificity of 95% (95% CI 84-99%), a positive predictive value of 87% (95% CI 60-98%), and a negative predictive value of 91% (95% CI 79-98 %). In comparing the readings the nurse obtained from the two different tympanic thermometers, the mean absolute difference was 0.24 +/- 0.22 degrees C. Nurses detected fever with a sensitivity of 94% (95 % CI 71-100 %), a specificity of 88% (95% CI 75-96 %), a positive predictive value of 76% (95% CI 53-92%), and a negative predictive value of 97% (95%CI 87-100 %) using the home thermometer. The intraclass correlation coefficient for the three sets of readings was 0.80, and the consistency of readings was not affected by the body temperature. CONCLUSIONS: The readings done by parents with a tympanic thermometer designed for home use differed a clinically significant amount from the reference standard (readings done by nurses with a model of tympanic thermometer commonly used in hospitals) the majority of the time, and parents failed to detect fever about one-quarter of the time. Tympanic readings reported by parents should be interpreted with great caution.

Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
