An urban Italian study on emergency room utilisation by immigrants suffering from mental disorders in Rome, 2000-2004

To compare Emergency Room (ER) utilisation by subjects diagnosed as suffering from a mental disorder, who were born in Strong Migratory Pressure Countries (SMPC) or in Italy. To evaluate the predictors of admission to psychiatric and to non-psychiatric wards.

Data collected from Information System of Emergency Rooms were analysed. ER contacts in the years 2000-2004 pertaining to subjects who received a psychiatric diagnosis (ICD9-CM codes), and who were born in SMPC or in Italy were examined. "Contacts" included a total of 68,867 assessments made in the ER of all general hospitals in Rome having an acute psychiatric ward. Gender, age and clinical information on SMPC-born and Italian-born patients were compared. A multinomial logistic regression analysis was performed in order to determine risk factors for admission to a psychiatric or to a non-psychiatric ward.

At the end of follow-up, 11.7% of ER contacts concerned patients born in SMPC. Compared to the Italian-born group, these patients were younger and received more frequently a diagnosis of "Alcohol and substance abuse and dependencies", while admissions to a psychiatric ward were significantly less common.

Monitoring health service utilisation may provide relevant information for the delivery of culturally sensitive mental health services.
