Abstract
This paper discusses the development and implementation of a specialty dual-disorders treatment program in an acute-care psychiatric hospital. Both the positive aspects and the problems encountered in developing this program are reviewed. Empirical studies of the prevalence of dual disorders are reviewed and the possible relationships between psychiatric illness and substance use disorders are briefly delineated. Descriptions are provided on the assessment and treatment components of this program as well as the types of patients treated during the first year. Finally, recommendations are provided regarding the integration of a dual-disorders program in an acute-care psychiatric hospital.
