Infection and BAHAs

Hi everyone, I'm part of a team of engineering students working on a project with BAHAs.

We've decided on a potential design to reduce infection rates and are trying to understand more about infection/skin problems among BAHA users. If you have a BAHA or know someone who does, would you mind sharing some of your experiences? Things like how often infections occur and what you do to treat it. Would you be willing to pay to reduce these concerns (another $10?, $50?, >$100? or no money at all?). Thanks!!
