[Depressive disorders and antidepressive therapy. A comparison of neurology practice and psychiatric clinic]

It is a question of great importance when psychiatric patients should be treated as inpatients or as outpatients. This decision depends on therapeutic as well as economic considerations. However in depression, as in other mental illnesses, many cases could reasonably be treated as in- or outpatients alike. Despite the importance of this question, there is to our knowledge no epidemiological study which compares patients in inpatient and outpatient settings within the current German medical system. 1300 inpatients and 5376 outpatients were investigated using identical methodologies within a drug utilization study of the antidepressant venlafaxine. Inpatients were found to be more severely ill and have a recurrent course of illness and higher rates of comorbidity. Outpatients more often had a chronic course. Inpatients were treated more often and with a wider variety of medication than outpatients, with the exception of phytopharmaceuticals. Venlafaxine was given in higher doses in the inpatient setting and combined more often with other psychotropic medications. Complaints of adverse drug reactions were comparable in both groups. Nausea was the most frequent, reported by 9.7% of inpatients and 15.2% of outpatients. The data show that the distribution of patients in outpatient and inpatient settings corresponds to the stepwise structure of the German health care system.
