Development of service intensity criteria and program categories for individuals with co-occurring disorders

Many patients present a clinical situation in which psychiatric symptomatology and substance related symptomatology are inextricably intertwined. A paradox exists for these patients, in that both the addictions and mental health systems of care, and the level of care assessment methodologies associated with each system, are designed for one type of disorder only, or only one disorder at a time. As a result, these individuals are perceived as system misfits. Our inability to assess these patients accurately and place them appropriately contributes to poor outcomes and high costs. These costs consist of expensive utilization of scarce system resources. There is a growing need for a more integrated methodology for level of care assessment, in which both psychiatric and substance symptomatology can be assessed simultaneously to generate a wider array of programmatic interventions for individuals with co-occurring disorders. This article describes efforts to build upon the Patient Placement Criteria published by the American Society of Addiction Medicine, Second Edition (ASAM PPC-2) to develop a revised instrument that is much more capable of evaluating the placement needs of individuals who present with combinations of psychiatric and substance symptomatology.
