title: Analysis of clinical characteristics and antipsychotic medication prescribing practices of first-episode schizophrenia in Israel: a naturalistic prospective study.
abstract: BACKGROUND
  Investigation of the clinical presentation and treatment of first-episode psychosis is important in order to exclude effects of age, chronic illness, long-term treatment and institutionalization. The aim of this descriptive study was to investigate the management practices of first-episode schizophrenia in a cohort of patients in Israel and to document use of the various "typical" or "atypical" antipsychotic agents.
  
  
  METHODS
  Fifty-one consecutive patients (26 M, 25 F) with first-episode psychosis were recruited for study participation and were administered either typical or atypical antipsychotic medications in a naturalistic manner.
  
  
  RESULTS
  While an approximately equal number of subjects received typical and atypical medications at illness onset, a prominent shift to atypical antipsychotic treatment occurred over the study course; 18 subjects had medication class shifts: 17 from typical to atypical, and one from atypical to typical. Negative symptoms did not affect length of hospitalization, but were associated with aggression. Higher depression rates were noted in patients with long hospitalizations who received typical antipsychotic medications. Immigrants were admitted at an age approximately four years older than native-born Israelis.
  
  
  CONCLUSIONS
  The prominent shift from "typical" to "atypical" antipsychotic medications may indicate sensitivity of first-episode psychotic patients to side-effects of "typical" medications and prominence of use of atypical medications in this patient subpopulation be it due to improved efficacy over time or successful marketing. Unique cultural and population characteristics may contribute to the manifestation of first-episode psychosis and suggest the importance of more effective outreach to the immigrant population in order to manage an apparent treatment delay.
