Abstract

Background: The aim of this study was to validate the use of temperature sensors to accurately measure thermoplastic volar forearm splint wear in a healthy cohort of volunteers using 5- and 15-minute temperature measurement intervals.

Methods: A prospective diagnostic study was performed to evaluate the diagnostic accuracy of temperature sensors in monitoring splint wear in 8 healthy volunteers between December 2022 and June 2023. Temperature sensors were molded into thermoplastic volar forearm splints. Volunteers who were familiar with the study aims were asked to keep an exact log of the time spent wearing the splint ("actual wear time"). Sensors recorded temperatures every 5 or 15 minutes, and separate algorithms were developed to determine the sensor-detected wear time compared with the actual wear time as the gold standard. The algorithms were then externally validated with the total population.

Results: The 5-minute and 15-minute algorithms demonstrated excellent sensitivity (99.1% vs 96.6%), specificity (99.9% vs 99.9%), positive (99.4% vs 99.5%) and negative (99.9% vs 99.3%) predictive value, and diagnostic accuracy (99.8% vs 99.3%), respectively. The 5-minute algorithm recorded 99.5% of the total splint hours, whereas the 15-minute algorithm recorded 96.1%. There was no significant difference between the actual time per wear session (5.4 ± 2.7 hours) and the time estimated by the 5-minute algorithm (5.4 ± 2.6 hours; P = .40), but there was a significant difference for the 15-minute algorithm (5.2 ± 2.6 hours; P < .001).

Conclusion: Temperature sensors can be used to accurately monitor thermoplastic volar forearm splint wear.

Level of evidence: Diagnostic II.

验证温度传感器以监测手部手术患者的热塑夹板磨损情况。

背景：本研究的目的是验证温度传感器在健康志愿者群组中准确测量热塑性前臂夹板磨损情况的有效性，温度测量时间间隔为 5 分钟和 15 分钟：在 2022 年 12 月至 2023 年 6 月期间，对 8 名健康志愿者进行了一项前瞻性诊断研究，以评估温度传感器在监测夹板磨损方面的诊断准确性。温度传感器被模塑在热塑前臂夹板中。熟悉研究目的的志愿者被要求精确记录夹板的佩戴时间（"实际佩戴时间"）。传感器每 5 或 15 分钟记录一次温度，并开发出不同的算法来确定传感器检测到的佩戴时间与作为黄金标准的实际佩戴时间的比较。然后，这些算法在所有人群中进行了外部验证：结果：5 分钟和 15 分钟算法的灵敏度（99.1% vs 96.6%）、特异性（99.9% vs 99.9%）、阳性预测值（99.4% vs 99.5%）和阴性预测值（99.9% vs 99.3%）以及诊断准确性（99.8% vs 99.3%）分别非常出色。5 分钟算法记录了总夹板时间的 99.5%，而 15 分钟算法记录了 96.1%。每次穿戴的实际时间（5.4 ± 2.7 小时）与 5 分钟算法估计的时间（5.4 ± 2.6 小时；P = .40）之间没有明显差异，但 15 分钟算法有明显差异（5.2 ± 2.6 小时；P < .001）：结论：温度传感器可用于准确监测热塑前臂夹板的佩戴情况：证据等级：诊断 II。
