The mean dose of maintenance treatment is 105.357. Before the treatment, the quantity of total number of hospital admission are 1.14 versus 0.429 after treatment. The number of stay is also decreased from 13.7 to 3.5; like emergency room visits or to other devices. 78.57% of patients continue to psychopharmacological treatment. Fifty percent of patients undergoing treatment with another antipsychotic (P < 0.05).
