ZEPPEGNO, Patrizia et al. First admissions for psychoses in Eastern Piedmont-Italy. Eur. J. Psychiat. [online]. 2009, vol.23, n.3, pp.153-165. ISSN 0213-6163.

Background and Objectives: 1) To identify the sociodemographic, anamnestic characteristics and presentation symptoms of patients, at the time of first hospitalization, associated with a discharge diagnosis of schizophrenic versus non-schizophrenic psychoses; 2) to define risk factors, at the time of the first admission, for a rehospitalization, regardless of reasons for readmission; 3) to assess the diagnostic stability between first and second hospitalization. Methods: This study includes 245 patients first admitted to the University Psychiatric Clinic of Novara in a period of seven years, discharged with a diagnosis of psychosis as reported in the Discharge Register (ICD-9-CM codes 290-299). Data were collected by consulting medical records and registers of community-based services of the South Novara Mental Health Department. A logistic regression model was used to determine the characteristics associated with a discharge diagnosis of schizophrenia. The relationship between the risk of rehospitalization and patients characteristics was studied using Cox,s regression analysis. Results: Risk factors for a discharge diagnosis of schizophrenia were age, compulsory admission, positive symptoms, and previous non-psychotic psychiatric episodes. Risk factors for rehospitalization were a diagnosis of schizophrenia, an age of less than 40 years, the absence of a stable affective relationship, and living with the family of origin. The 92% of the patients diagnosed as schizophrenic on the first hospitalization had the same diagnosis on readmission. Conclusions: Schizophrenia differs from other psychoses in terms of the greater prevalence of both some symptomatological characteristics and an history of previous non psychotic episodes. Some sociodemographic and clinical characteristics at the time of the first hospitalization can provide indications useful in preventing rehospitalization.
