A preliminary study, in which a total of 43 patients were included
in this two-year, mirror-design study. The types of service utilization
(inpatient, ER, outpatient), medication costs, and overall costs were
measured in a 1-year period prior to and then after risperidone
initiation. Clinical measures to document symptom improvement were done
at medication initiation and at 6 months.

-
78% Reduction in inpatient
utilization occurred after risperidone was initiated.
-
60% Reduction in acute ER
utilization occurred after risperidone initiation.
-
