A study of patterns of neuroleptic dosage for 206 schizophrenic inpatients
showed significant differences over time and among three centers--a general
hospital psychiatric unit, a community mental health center, and a state
hospital. In 1982 patients' mean dose at discharge was higher than the peak
mean daily dose in 1973, and high-potency neuroleptics were being used
almost exclusively. The mean length of stay decreased from 49 days in 1973
to 34 days in 1982. The possible relationship, if any, between increasing
dosage, decreased length of stay, and the switch from low-potency to
high-potency neuroleptics remains undetermined.
