In China, the Thermia-empowered iThermonitor has gained popularity among digitally-savvy parents who have purchased the wearable device to monitor their child's temperature. When iThermonitor detects a fever, parents can access Thermia via web or mobile and answer online questions about the child's current symptoms and medical history.
Data collected from these interactions is anonymized and analyzed by the Boston Children's team to enable disease tracking. Using this method, the team collected nearly 45,000 data points from China's Thermia users between 2014 and 2016. They discovered that outbreaks of "influenza-like illnesses," which had the hallmark signs of influenza, could be detected digitally in real time.
In comparison to the influenza surveillance data collected by the National Health and Family Planning Commission (NHFPC) of the People's Republic of China, the data from iThermonitor and Thermia revealed influenza outbreaks an entire month earlier.
A new wireless axillary thermometer from Raiing Medical uses a proprietary system, iThermonitor (WT701), to provide better estimates of core temperature than a conventional axillary probe. Improvement results in part because the axillary probe measures and records temperatures continuously every 4 seconds and includes software to compensate for ambient temperature and positional changes including arm abduction.
Whether the iThermonitor is sufficiently accurate for clinical use remains unknown. The investigators thus propose to evaluate the system in perioperative patients who often experience thermal perturbations over a range of several °C. Specifically, the investigators propose to determine the precision and accuracy of iThermonitor in surgical patients and during the initial hour of recovery. As in previous studies, the investigators will consider the thermometer sufficiently accurate for clinical use if most Raiing temperatures are within ±0.5°C of the reference temperature.
This is a pilot study to evaluate the use feasibility of the iThermonitor, a continuous temperature monitoring device, as a clinical support and patient self-management tool in the management of pediatrics patients on myelosuppressive therapies for acute leukemia and other childhood cancers.
