Reliability of Parent-Measured Axillary Temperatures

Background. Fever is a common symptom in children. Assessment of accuracy of parental temperature measurement is integral in determining proper medical management. Methods . The authors recruited 25 afebrile and 13 febrile children from outpatient sites. Participants had rectal temperatures measured by a trained study staff, followed by axillary temperature measurements by trained study staff and parent. Analysis of variance was used to compare the afebrile and febrile groups; the paired t test was used to compare parent and study personnel’s axillary temperature measurements. Analysis included the statistical significance of Pearson’s correlation coefficients for the various comparisons. Results. In both febrile and afebrile groups, the rectal temperatures were greater than axillary temperature measurements, but the difference was not consistent. There was a very high correlation (correlation coefficient range = .86-.96) between axillary temperature measurements performed by trained study staff and parents. Conclusions. Parental report of axillary temperature measurement can be considered reliable.
