title: [Integrated treatment of cooccurring mental and substance use disorders in urban       populations : the situation in Montréal].
abstract: The prevalence of patients diagnosed with both a psychiatric and an addiction disorder       is considerable. Like many other large urban centers, Montreal harbors many of these socially       marginalized individuals. In spite of a wide range of resources for the treatment of each       condition taken singly, there has been until recently an alarming dearth of programs aimed at       providing integrated treatment models. In recent years, the CHUM has endeavored to implement       such a program in order to address the multiple needs of a population often rendered       vulnerable in many respects. In this article, the authors address the magnitude of this "dual       diagnosis" problem, existing intervention models and the obstacles faced by this population in       terms of access to health care ; they describe the steps leading to the establishment of an       Addiction Psychiatric Unit at the CHUM and the challenges arising from the creation of a       multidisciplinary integrated treatment model in an urban setting.
