Noncompliance is a constant challenge. Maintaining hope is not always easy. Setting realistic expectations is difficult. These patients are often desperately poor. 1 The medications often seem to cause more harm than benefit. 1 One of my patients brought one card from his collection to each visit as a gift to my sons.

How should you behave 1,2 while treating these patients? Adopt a quiet, calm demeanor. Isolate your own emotional arousal.arousal Avoid perceived intrusion. Observe carefully. Listen intently. Know the diagnostic criteria. Ask brief clarifying questions. Avoid painful exploration. Review available records. Engage the patient’s family and social support network. Consider the differential diagnoses. Convey understanding, confidence and intent to help. Recommend the most appropriate medications. Explain most common side effects briefly. Explain treatment plan briefly. Invite questions. Begin educating the family about what to expect. Arrange for social support. Communicate with stakeholders. Arrange for follow up. 1 Begin with the result you want—this patient to receive the best possible care—then focus on those behaviors necessary. 2 The only behaviors you can really control are your own!

What have you learned? The first descriptions of schizophrenia date back to 1400 BC. Schizophrenia is currently viewed as a devastating group of disorders that involve – Deterioration from a previous level of functioning, – Characteristic symptoms involving multiple mental processes, – Typical psychotic symptoms during the active phases of the illness, and – A demoralizing, chronic course. Onset usually is in the patient’s teens and 20s. The treatment challenges are daunting. Antipsychotic medications are helpful but not dramatically so, and side effects are real problems in themselves. Only clozapine stands out; 1 the rest differ only in expense and side effects. Multi-modal intervention is the key to maximizing recovery and preventing relapse. 1 Lieberman, et. al., “Effectiveness of Antipsychotic Drugs in Patients with Chronic Schizophrenia,” The New England Journal of Medicine, September 22, 2005, Volume 353; (CATIE)
