PG - 528-32 AB - BACKGROUND: The reasons for poor treatment response in some patients with schizophrenia remain unclear. It is possible that misdiagnosis of nonschizophrenic disorders as schizophrenia could result in suboptimal pharmacotherapy in some patients. METHOD: To assess this possibility, 110 severely ill, chronic patients with a referral diagnosis of schizophrenia were comprehensively assessed and rediagnosed according to DSM-III-R criteria. Global Assessment of Function (GAF) and Clinical Global Impressions (CGI) ratings were made at admission and at discharge from the ward, after the implementation of individualized treatment plans. RESULTS: The diagnosis of schizophrenia was confirmed in 80 patients (73%) and revised to another type of psychotic illness in 30 patients (27%). The GAF and CGI ratings were similar at admission in patients with confirmed and revised diagnoses. All patients improved by the time of discharge (p = .0001); however, patients with a revised diagnosis improved more than those with confirmed schizophrenia (p = .02). Patients with a revised diagnosis were less likely to require continued hospitalization on chronic care wards (p = .004). At admission, medication regimens were similar in the two groups of patients. At discharge, patients with a revised diagnosis were less likely to have received neuroleptics (p = .007) and more likely to have received antimanic drugs (p = .0002) or electroconvulsive therapy (p = .0004). CONCLUSION: These findings from a clinical sample suggest that diagnostic reassessment is an important first step in the management of apparently refractory schizophrenia.
