Depression is among the most disabling and costly illnesses in the world. Despite good short-term efficacy outcomes in the treatment of depression, long-term outcomes remain disappointing. Depression continues to be missed or underdiagnosed and undertreated, and comorbidities are frequently not identified. ⋯ Patients who fail to achieve a full remission have a more recurrent and chronic course, increased medical and psychiatric comorbidities, greater functional burden, and increased social and economic costs. Cost-effective treatment for depression includes antidepressant therapies with higher remission rates. Antidepressants with a dual mechanism of action and combination therapies are associated with higher remission rates, more depression-free days, reduced pain-symptom morbidity, reduced health service utilization, and improved productivity.
