I spoke with a medical supplier about data logging. Many insurance companies are now requesting it....you guessed it, because they want to justify whether you are actually using their equipment. Some devices, like CPAP/VPAP machines have a built-in modem and they "call" it to see how often you use it. If you don't use it often, they take it away from you.
On hearing aids, I cannot say....it could be used for research purposes or to help the audi determine what settings are best.
