I have some confusion with your question but it is not your fault in describing the events. My confusion is why and how you could be "discharged" when it appears that you never "entered" a physician-patient relationship with the doctor and therefore you were never an established patient with that office so the word they gave you as "discharged" is misleading. In my experience and understanding, you have to be seen and have been interviewed by the doctor (or the doctor's assistant healthcare provider) to develop any relationship that can be terminated. The patient and the doctor first meet together and both agree to continue to the relationship which means that the patient gives the doctor the permission to ask personal questions with the patient answering and then permission for the doctor to record the patient's history and/or allows the doctor perform a physical examination on the patient's body. The doctor must be willing, if accepting the patient, to assume responsibility for the health issues the patient presents and is professionally and legally at that point unable to abandon his or her patient. If the two first meet and one party disagrees to establishing such a relationship, then each go their own way and NO doctor-patient professional relationship has been established and therefore there would be no such thing as "discharging" the patient. "Blacklisting", notifying other physicians about behaviors of patients which the original physician dislikes perhaps to discourage the other physician from assuming care of the patient is generally unprofessional and not acceptable. But to "blacklist" a patient where the doctor-patient relationship have never been established is irrational.

Yes, compliance with scheduled appointments is important for patients who have established the patient-doctor relationship as described above since patient compliance is an important element in the development of a successful outcome of the patient's illness and should be an element of responsibility of the patient along with other compliance issues. But most patients don't have lives which are so immutable that there is no chance that an appointment will not always be met. The doctor and office staff must accept that change of appointment dates is part of normal lives and is allowable based on reasonable explanations. If a doctor-patient relationship has already been established, it can be terminated only by the physician referring the patient to another source of medical care...otherwise it could be argued that the doctor abandoned the patient. If no doctor-patient relationship has been, established as suggested by your experience, as I already noted each party can go their own way with neither having to defend their own reason but also not to intimidate the other party. I am a physician and member of a hospital ethics committee and not a lawyer so this is not a "legal" answer but represents what I understand is involved in medical practice. I hope this helps you more fully understand the issue that you are dealing with. Good luck. ..Maurice.
