How do we make this easier?

As I am talking with nursing homes and other long term care centers about using health information exchange (HIE), there is a lot of positive feedback, yet, I am encountering a similar story.  That is...the facility only trained one person to use HIE, and when that person left his/her job for a new job... no one was left who knows the ins and outs of using HIE.  So, what can we do about this?   It would be great to train as many staff members as possible for using the system. Perhaps we need to move to a model of not only training more people, but also using a "train the trainer" method.   Employee turnover can be problematic for long term care.  We need to help ourselves by preparing others in the organization to learn the best ways to use HIE (and other health technologies).  Ideally, HIE needs to be easier to use.  What can we do to make this easier?
