To assess the agreement between infrared emission detection (IRED) ear and rectal temperatures and to determine the validity of IRED ear thermometry in detecting rectal fever.
Prospective, convenience sample, unblinded study.
An acute geriatric unit (teaching hospital) and a multidisciplinary intensive care unit.
The study included 45 inpatients (26 women and 19 men), aged 78.3+/-6.9 years, admitted over a 4-month period. Twelve of the patients were definitely infected.
Sequential rectal (RT) and ear temperature (ET) measurements were performed using mercury-in-glass and IRED ear thermometers, respectively. IRED ear temperatures were measured at both ears (unadjusted mode), with the highest of six ear temperatures considered the true value.
Mean RT (37.39 degrees C +/- 0.52 degrees C) was significantly (P<.001) higher than mean ET (36.89 degrees C +/-0.59 degrees C). A highly significant positive correlation was found between RT and ET (slope = 0.69; 95% CI, 0.52-0.86; P<.001; r = 0.78). The mean bias (mean of the differences) between RT and ET was 0.50 degrees C +/-0.37 degrees C (95% CI, 0.41 degrees C-0.59 degrees C), and the 95% limits of agreement -0.22 degrees C and 1.23 degrees C (95% CI, -0.38 degrees C to 1.39 degrees C). According to the standard criterion (RT > or =37.6 degrees C), 14 patients were febrile. Using an optimum IRED ear fever threshold (37.2 degrees C), the sensitivity and specificity of IRED ear thermometry for predicting rectal fever were 86% and 89%, respectively (positive predictive value, 80%; negative predictive value, 93%).
The degree of agreement between rectal temperature and the highest of six IRED ear temperatures was acceptable. Using an optimal IRED ear fever threshold of 37.2 degrees C (99 degrees F), IRED ear thermometry had acceptable sensitivity and specificity for predicting rectal fever.
评估红外发射检测(IRED)测量的耳部温度与直肠温度之间的一致性,并确定IRED耳部测温法在检测直肠发热方面的有效性。
前瞻性、便利样本、非盲法研究。
一家急性老年病科病房(教学医院)和一个多学科重症监护病房。
该研究纳入了45名住院患者(26名女性和19名男性),年龄为78.3±6.9岁,在4个月的时间内入院。其中12名患者确诊感染。
分别使用玻璃体温计和IRED耳部体温计依次测量直肠温度(RT)和耳部温度(ET)。在双耳测量IRED耳部温度(未调整模式),将六个耳部温度中的最高值视为真实值。
平均直肠温度(37.39℃±0.52℃)显著高于平均耳部温度(36.89℃±0.59℃)(P<0.001)。直肠温度与耳部温度之间存在高度显著的正相关(斜率=0.69;95%CI,0.52 - 0.86;P<0.001;r = 0.78)。直肠温度与耳部温度之间的平均偏差(差值的平均值)为0.50℃±0.37℃(95%CI,0.41℃ - 0.59℃),一致性界限的95%为 - 0.22℃和1.23℃(95%CI, - 0.38℃至1.39℃)。根据标准标准(直肠温度≥37.6℃),14名患者发热。使用最佳的IRED耳部发热阈值(37.2℃),IRED耳部测温法预测直肠发热的敏感性和特异性分别为86%和89%(阳性预测值为80%;阴性预测值为93%)。
直肠温度与六个IRED耳部温度中的最高值之间的一致性程度是可以接受的。使用37.2℃(99℉)的最佳IRED耳部发热阈值,IRED耳部测温法在预测直肠发热方面具有可接受的敏感性和特异性。
