Abstract
The various method used to measure body temperature has both advantages and disadvantages including the age old mercury–in-glass thermometers. Currently, there are variations in measurements with different methods as well as conflicting opinions about the optimal anatomic site for measuring body temperature. However, In this study, we aimed to assess the accuracy and reliability of thermometric measurements obtained from the axilla with two different automated digital thermometer and age-old mercuryin-glass thermometer. 115 participants were involved in this study,73(33m;40f) of age 24.53±5.67 were students from an higher institution while 42(20m;22f) of age 27.25±26.51 were hospitalized patients. Simultaneous axillarytemperature measurements (n: 115) were performed with the mercury-in-glass, Omron and wellbeing digital thermometers. The mean results of the axillary mercury–in-glass thermometers and axillary digital thermometer were 36.89 ± 0.27, 36.75 ± 0.4, 36.6±0.46 for the student group while the hospitalized group were 37.3±0.77,37.347±0.76 and 37.26±0.75 respectively.The Bland-Altman plot of differences suggests that 95% of the two Digital thermometer readings were within limits of agreement of +0.56 to –0.85°C and 0.44 to -1.01 for Omron and Well-being respectively among the student group .while the hospitalized group was 0.5 to -0.42 and 0.39 to -0.47 for the respective thermometers,when mercury-in-glass thermometer is considered as the standard. Our results showed that limits of agreement were wide between readings of axillary mercury–in-glass thermometers and digital thermometers but narrow for hospitalized groups with higher temperature readings. There was no statistic significant difference among the methods in febrile temperatures except lower temperatures.Result also revealed that digital thermometer under-reads lower temperatures. Furthermore, Higher Axillary readings of mercury thermometer were same with the digital thermometers supported by correlations at r=0.9520 and 0.9595. Therefore, digital thermometercan be used interchangeably with mercury thermometer in clinically febrile patients but neither in apparently healthy persons nor experimental research that are sensitive for lower body temperatures.
