Therefore, we investigated the relationship between the examination rate of TRS and the prescription rate of clozapine.<\/jats:p><\/jats:sec><jats:sec><jats:title>Methods<\/jats:title><jats:p>After attending a 1\u2010day educational program on schizophrenia based on the \"Guidelines for the Pharmacological Treatment of Schizophrenia,\" we asked the participating facilities to submit records of whether or not TRS was evaluated for each patient. We calculated the clozapine prescription rate from the schizophrenic patients prescribed clozapine and all of the schizophrenic patients. Forty\u2010nine facilities in 2017 were included in the study.<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>There were dichotomous distributions in the examination rate of TRS and a non\u2010normal distribution in the prescription rate of clozapine.

Clearly, further clinician training is needed for the early detection and appropriate management of TRS that includes an explanation of TRS and how to introduce clozapine therapy to patients and their
