A total of 56 patients were included in this two-year study. Fifty-six patients continued to receive olanzapine for 12 consecutive months. The types of service utilization, medication costs, and overall costs were measured in a 1-year period prior to and then after olanzapine initiation. Clinical measures to document symptom improvement were done at medication initiation and 6 months later.

  • 85% reduction in inpatient utilization occurred after medication was initiated.
  • 80% reduction in acute ER utilization
  • 23% increase in outpatient services correlating with greater patient stabilization
  • Overall mean costs savings of $296 per pt/month. (n=56)
  • Significant  improvement in symptoms of schizophrenia
