I've used Healthgrades for a while now as a general guide, realizing its potential weaknesses. However, I have yet to see a superior system. If anyone knows of one, I'll be glad to hear of it and give it a shot.
I asked my primary about Healthgrades, she said she's not familiar with it.
This is someone in her 60s who's been in practice for decades. I'm a wee bit shocked.
Glad to hear your thoughts, opinions, and experiences.
