Collaborative Care model in mental health. Scope and experiences after three years of activity in Mexico City

Aim The aim of this study was to evaluate the experience of the Collaborative Care model with general practitioners (GPs) for diagnosis and treatment of depression and anxiety disorders in primary care centers (PCC).

For many years, different ways to address mental health problems in primary care settings have been evaluated. However, there is still debate over how to treat psychiatric conditions in such a context.

A cross-sectional design was used. The study was conducted in two consecutive studies in six PCC that serve marginalized population in Mexico City. In the first study, cases were interviewed, diagnosed, and treated by a psychiatrist. In the second study, Collaborative Care model was used and GPs were trained; psychiatrists diagnosed and treated patients but GPs discussed the symptoms and treatment of the patients with the psychiatrist. Findings First study: 18 patients with depressive and/or anxiety disorders were interviewed; these cases were not discussed between the GPs and the psychiatrist. Second study: psychiatrists and GPs conducted joint interviews and cases were discussed. From the 399 evaluated individuals, 38.94% were diagnosed with a depressive disorder. After the Collaborative Care model was applied, GPs were more aware about mental health problems and they were more interested in the identification of these conditions in PCC. Replication studies will help confirm the effectiveness of this model.
