 EQUIP was a controlled trial of the care model. At two VA medical centers, clinicians n66 and their patients n398 were randomized to an intervention or a control condition. In the intervention group, a chronic care model was implemented for 15 months. Before, during, and after implementation, surveys and semi-structured interviews were conducted with clinicians and managers to assess their clinical practices, competencies, expectations, experiences, and observations concerning the implementation. Data sources included patient interviews, clinician interviews, and data from VistA. The feasibility of more broadly implementing the collaborative care model was assessed utilizing qualitative and quantitative information about the models strengths and weaknesses, factors that facilitatedimpeded implementation, direct costs of implementation and maintenance, and effects on treatment service utilization.
