At the end of this session, participants will be able to: 1) Appreciate the prevalence of specific concurrent disorders; 2) More effectively choose between available guidelines; and 3) Discuss clinical aspects of integrated care for concurrent disorders.

The workshop is based on recent publications by the presenters and focuses on clinical care for concurrent disorders, also called dual disorders or co-occurring disorders. All presenters are clinicians working in the field of concurrent disorders and base their academic work on clinical experience. Presenter one will provide an introduction and summarize recent findings on the prevalence of concurrent disorders based on his recently published work in this area. Then, presenter two will discuss available concurrent disorder guidelines, their relevance, quality, and gaps. This part of the workshop is based on his recent systematic review of all available English-language guidelines for concurrent disorders. The second half will provide a discussion of clinical approaches. Presenters three and four currently work at the largest treatment centre focused on concurrent disorders, the Red Fish Healing Centre for Mental Disorders and Addiction. The 105-bed centre in Coquitlam, BC, provides tertiary care for severe concurrent disorder patients for British Columbia. Presenters will use a clinical case to discuss the practical clinical application of integrated care for concurrent disorders. The workshop will allow sufficient time for discussion and questions.
