Initial psychotropic prescriptions and symptom associations in first-visit patients with major depressive disorder: A...

There are limited reports regarding psychotropic prescriptions in first-visit patients with major depressive disorder (MDD). The objective of this study is to clarify the prescription patterns of psychotropics and their association with symptoms among first-visit patients with MDD in Japan.

In this cross-sectional analysis, we examined 376 first-visit patients diagnosed with MDD. Depressive symptoms were evaluated using the Quick Inventory of Depressive Symptomatology Japanese version (QIDS-J). To assess personality traits, we administered the Japanese version of the Ten Item Personality Inventory (TIPI-J), and psychotic symptoms were evaluated using the PRIME Screen-Revised (PS-J).

Among the first-visit patients with MDD, 31.4% (118/376) were prescribed antidepressants, and 18.1% (68/376) received benzodiazepines. Overall, 40.2% (151/376) of the patients were prescribed at least one psychotropic medication. In a multivariate logistic regression model using the forced entry method, missing data on educational attainment and the view of myself domain of the QIDS-J were negatively associated, while the concentration/decision-making domain of the QIDS-J was positively associated with antidepressant prescription.

More than half of the first-visit patients did not receive any psychotropic medication. Psychiatrists appear to consider specific symptoms and personality traits when deciding whether to prescribe medications, which may also be influenced by patient preferences. Further studies, including longitudinal analyses, are needed to explore these associations in more detail.
