Yes, I do believe that the first psychiatrist did call the general practitioner and they had a discussion regarding that. They both had concerns for my mom's mental health.
Another thing to note is that they all worked together in a professional manner as well. They knew my mom from a professional standpoint, as well as having a person-doctor relationship, so they could see her deterioration. They both have said—it's documented in her medical records—that they did not believe she should go through with MAID.
