Background. Underrecognition and undertreatment of depression in primary care has been regarded as a major public health problem. In contrast, some studies found that among patients labeled as depressed by primary-care physicians (PCPs), a relevant proportion do not satisfy international diagnostic criteria for depression. The aims of this study are: (1) to assess disparity between PCP diagnosis and research diagnosis of depression; (2) to compare antidepressant treatment in concordant and discordant cases of depression. Methods: Data are gathered from a national survey on depressive disorders in primary care, conducted with the collaboration of 191 PCPs. Three hundred and sixty-one PCP patients were evaluated, and their psychiatric diagnosis was established by the 'unaided' PCPs and by using a research interview for depression. Results: PCPs recognized 79.4% of cases of depression and prescribed antidepressants to 40.9% of them. Yet, 45.0% of patients labeled as depressed by the PCPs were not cases of depression according to ICD-10 criteria; 26.9% of false-positive cases received an antidepressant. Globally, 35% of antidepressants for 'depression' were prescribed to false-positive cases. Conclusions: Underrecognition and undertreatment of depression in primary care seem to be less alarming. Conversely, PCP diagnoses of depression appear to be more inclusive than psychiatric diagnostic criteria. A possible consequence of this apparently more inclusive diagnostic threshold may be an excessive use of antidepressants. These changes require a corresponding change in research, toward efficacy and safety of the treatment of milder cases, and in education, toward the distinction between the management of mild and severe cases of depression.
