the "best doctors" in my eyes are the ones with the best outcomes,
  lowest utilization, highest efficiency and highest patient 
  satisfaction. 

As a lay-person, how can I tell which institutions or doctors have the best outcomes, and patient satisfaction? How can I make smarter choices about where I take my family for medical help?

  I think those are the best doctors and it's what I'm striving to be.

As a doctor, how do you measure this? How do you know you're becoming better and in which areas you need to focus?
