简要总结
People with intestinal stomas (especially an ileostomy) can have, despite development of better ostomy products, problems with leakage which influence their quality of life negatively.
To overcome this, Coloplast has developed a new supporting ostomy product, which has an adhesive sensor layer that should be place underneath the baseplate normally used by the subject.
Single arm design. Open-labelled Study duration: 21 days + 3 days.
详细描述
Test product is a Digital Leakage Notification System. It consist of a sensor layer (worn beneath the baseplate), a transmitter attached to the sensor layer, a charger for charging of transmitter and an app, to be installed on a smartphone, which notifies the user of the status of their baseplate such as everything looks okay or there is a possible leakage.
Subjects are asked to use test product for 21 days. n=15 were using a phone with Android operating system and n=10 a phone with iOS operating system.

结局指标
主要结局
System Performance Accuracy of Pictures
时间窗: 21 days
The primary endpoint is system performance accuracy: * True Negative: No leakage observed on picture and no leakage detected by system * True Positive: Leakage observed in picture and leakage detected by system * False Negative: Leakage observed in picture, but no leakage detected by system * False Positive: No leakage observed in picture, but leakage detected by system
