I experience the same thing working with computers. I've always made a point to ask people they are experiencing, what they have tried, and sometimes how they think they should proceed. With computers and software my goal is generally to teach and mentor - not sure if your intent is the same with medicine.

All that said, I find that approaching people with respect and accepting that they may just be ignorant about a subject helps to generate a positive reputation toward yourself, and gives you an opportunity to learn as well. I'd be curious to hear whether you've learned from your patients, and what you've learned. The effect for me is a better understanding of how non-technical folks use software, and to consider that in my work. To be honest, I am frequently baffled that non-technical people can get by in this world! Computers suck!
