Class of 2007 Abstract / Objectives: A prescription claims database from COPE Behavioral Services in Tucson, Arizona was used to retrospectively assess the differences between patients receiving <4 and those receiving > 4 psychotropic medications over a 12-month period in adult patients with schizophrenia.
Methods: Medication groups (i.e., < 4 versus > 4 concomitant psychotropic agents) were compared for differences in gender, age, duplication of antipsychotic therapy, adherence rates, court order treatment status, psychiatric hospitalization rates and length of stay, cost of services provided, and concomitant psychotropic medications.
Results: A total of 506 adult patients with schizophrenia (F=214 and M=292) met the inclusion criteria for receiving psychotropic medications during the 12-month study. Of those, 388 patients (76.7%) were found to have an average of < 4 medications, while 118 patients (23.3%) were found to have > 4 medications. Duplication of antipsychotic therapy was more common in the > 4 group (29.7%) compared to the < 4 group (3.1%), p < 0.001. Psychotropic adherence rates were significantly higher in the > 4 group based on month’s supply of prescriptions. Demographic differences between groups included: increased age, more women, fewer court order status, and higher cost of care in the > 4 compared to the < 4 medication group. No differences in hospitalizations, length of stay, and hospital costs were found between groups.
Conclusions: Our findings suggest that patients with schizophrenia with increased rates of polypharmacy have higher adherence rates, more duplication of antipsychotics, and a higher cost of care (i.e., case management, laboratory, other services, total prescription costs) compared to patients receiving < 4 psychotropic medications.
