The medical care abuser: differential diagnosis and management.

The differential diagnosis of patients who are abusive of or seem addicted to medical care is discussed using the approach outlined in the new Diagnostic and Statistical Manual III of the American Psychiatric Association. These are generally chronic disorders and their managements, using the substance abuse/addiction model, are aimed at protecting both patients and physicians from unnecessary, expensive, and potentially lethal medical interventions. The disorders considered include somatization disorder (Briquet's syndrome), psychogenic pain disorder (psychalgia), hypochondriasis, factitious disorder, and malingering.
