The previous discussion presumed that the physician would be treating or at least directly dealing with the patient in a situation where the patient has an expectation that there is a traditional physician relationship. There are many physicians, such as radiologists and pathologists, who make professional judgments about patients, but who do not have a direct relationship with patients. Occupational medicine physicians have a direct relationship with the patient, but not in a situation where the patient has the reasonable expectation of a traditional physician–patient relationship. (See Occupational Medicine) All physician-patients relationships are modified by circumstances of the provider's specialty.
