There are times where I know why the patient left. Something my staff did (who are always forthcoming in telling me what they did, right, lol) or something I do. I send a letter, apologizing and letting them know I understand. I let them know we will always be here if they want to come back.
The others are are let back are those who actually take the time to either call, write or talk to me in the office.
I have had two patients who, after I rounded on three of their babies, but not the fourth because I simply cannot continue to keep my privileges as a solo practitioner. I will say if they let me know and let me know their frustration, I would visit. But, how can a patient not understand the need for you to no longer go to the hospital each time. They left. Please try to come back.
So, I guess it comes down to:
1. Leaving the area (a no brainer)
2 Leaving due to my mistake (they don't tend to come back)
3. Someone with the guts to talk to me or send a letter.
