device-device interaction
Also written as: DDI
Electromagnetic interference between multiple implanted devices affecting function, requiring special consideration in multi-device patients.
Full Definition
Device-device interaction (DDI) occurs when multiple implanted medical devices in the same patient interfere with each other's normal operation through electromagnetic coupling or mechanical proximity effects. Common scenarios include interactions between cardiac devices and neurostimulators, insulin pumps, or other implanted systems. Medical editors must recognize DDI documentation requirements for multi-device patients, including specific programming modifications, implant positioning considerations, and ongoing monitoring protocols to ensure optimal function of all implanted systems.
Usage
Usage note: Specify all involved device types; include programming modifications and monitoring requirements; distinguish from external EMI.
