Sometimes, you just need to know who to contact. I had a patient the other day that I was very distinctly unhappy about her treatment from another doctor. I was talking to the nurse-manager of L&D, who encouraged me to email that doc's boss.
So I did. And I spontaneously decided to cc the higher-ups in admin. The next day, I was rounding on L&D. The nurse-manager came up to me and said with a smirk "Look at the hornet's nest you stirred up!"
Amazing what the cc line of email can do.
