Managing antidepressants in primary care: physicians' treatment modifications

To examine antidepressant management practices in primary care, patients (N = 148) given an antidepressant for at least one month completed the Beck Depression Inventory (BDI-II), the Patient Health Questionnaire-9 (PHQ-9), and a demographic survey. Participants' mean age was 50.7 yr. and 80% were women. Patients' charts indicated whether physicians had made changes to prescribed antidepressants or dose either 6 wk. before or 6 wk. after study entry. For the 87% of participants whose depression status could be determined, 10% met dysthymic disorder criteria and only 33% had had a medication change in the previous month. Major depressive disorder occurred in 37% but only 18% had had a medication change. Co-existing dysthymic disorder and major depressive disorder were diagnosed in 34%, with 24% receiving a medication change. Participants not receiving a medication change had mean BDI-II scores indicating moderate depression. Lack of antidepressant adjustment suggests physicians may need to monitor depressive symptoms closely using protocols and prompts.
