Frankly, I think this is not the right question to ask.
The "Patient Portal" is no "hindrance" to the patient's health. It is a new tool provided by technology. I would first explain what it is, what it is designed to do, and how to start using it.
One always hears that one must be one's own health advocate. The Patient's Portal is where to start. Just because medical terminology in certain reports is beyond my knowledge does not mean I shouldn't read it, try to understand it and be able to query my doctor about it. And doctors are busy. Who better to keep track of things than me?
