INTRODUCTION: Temporal artery thermometry has become a popular,<br />

convenient, and non-invasive way of obtaining critical vital signs in the<br />

emergency department (ED). However, speculation still exists regarding its<br />

accuracy in comparison to a more invasive, “gold standard” measurement: the<br />

rectal temperature. The aim of this study is to determine the accuracy of<br />

temporal artery thermometry compared with rectal thermometry in an adult ED<br />

population, and to evaluate a number of variables that may affect temperature<br />

differences, should they exist.<br />

METHODS: This prospective randomized study enrolled 200 adult ED patients<br />

presenting to a community teaching hospital in a four month period.<br />

Temperature recording was obtained from a patient population that met our<br />

inclusion criteria. Temperatures from the temporal artery and rectum were<br />

measured no more than five minutes apart. We tested the correlation between<br />

multiple variables and their effect on both methods of measurement using Bland-<br />

Altman plots and Spearman Rho correlations. T-test was utilized for direct<br />

comparison of the two methods of thermometry in the entire sample size.<br />

RESULTS: The mean temporal artery temperature across the entire sample size<br />

was 36.66°C±0.56°C, and the mean rectal temperature statistically higher, at<br />

37.31°C±0.92°C, p-value=0.001. We found that rectal temperatures were<br />

consistently higher than temporal wand temperatures, especially in febrile<br />

patients. In the febrile group, every single rectal reading was higher than its<br />

temporal wand counterpart and over 50% were at least 1.5ºC higher. Spearman-<br />

Rho analysis did not exhibit any statistical correlation between temporal artery<br />

measurement and age, sex, BMI, or time of measurement. There was poor<br />

correlation between rectal temperature and temporal artery temperature.<br />

CONCLUSIONS: We have demonstrated that temporal artery thermometry has<br />

poor accuracy for detecting fever and is a poor measurement of core<br />

temperature in an adult emergency department population.
