This is not really the correct forum or this question. What you are talking about is an Adobe Sign form. The responses are sent to the owner of the Adobe Sign Account from which the forms are sent. When you purchase Acrobat Pro you get a free Adobe Sign account.
For the Dr to get the responses he'll need to have an account and send the forms from that account. You can still build the forms, but they'll need to be transfered to him.
Maybe there is a way for you to set him up with a free account without purchasing Acrobat, but I don't know enough about the service to know how it all works. I do know that an Adobe Sign subscription can be purchased separately.
Here is a link to the Adobe Sign forum. I'm sure they'll know a lot more:

The Dr will need one or the other subscription. I don't know if Adobe sign is enough, but as Adobe is not a non-profit organisation, I won't think that the doctor can get a for free access to Adobe sign. I would also think that the price for the subscription depends on the number of forms that get sent out. And for sure, the doctor's account needs to send out the forms.
