Risperidone, an atypical antipsychotic, was introduced into clinical use
in New York State facilities in April 1994. In this chart review study,
records were reviewed for the first 63 patients started on risperidone at
the Bronx Psychiatric Center during 1994. Sixty percent of patients treated
with risperidone had a positive outcome, indicated by clinical improvement
either at discharge or in the hospital. Twenty- two percent required
termination of risperidone treatment within the initial three months.
Risperidone appeared to be associated with favorable outcome among chronic
state hospital patients, including those not discharged within the first
three months of treatment.
