Here is what you probably want:
1. A one2many field in doctor. You don't want to have a many2many record for each doctor record pointing to all its patients. That is inneficcient. You just need to retrive all patients that reference this doctor. That is what a one2many field does.
2. To automatically fill in information about a doctor what you need is:
1. A related field
2. Mark fields as readonly in the python source code
Read about related fields here:

The whole document itself is really good. It also talks about one2many fields.
