[Prevalence and effects of depressive and anxiety symptoms in internal medicine inpatients during the first year after hospital discharge].

In a prospective follow-up study the German version of the Hospital Anxiety and Depression Scale (HADS) was used to determine the prevalence of anxiety and depressive symptoms in internal medicine inpatients. From a total cohort of 376 admitted study patients questionnaires were completed at admission and after one year follow-up. The data demonstrated that the mean HADS score on the anxiety subscale decreased significantly from 6.7 3.5 at study inclusion to 5.8 3.8 after one year (p < 0.0005) while the mean HADS score on the depression subscale was relatively stable (5.3 3.6 versus 5.4 4.3, p = n.s.). Odds ratios for the prediction of positive HADS results at follow-up were 4.1 (95%-CI 2.0-8.4) for anxiety symptoms and 8.2 (95%-CI 4.6-14.6) for depressive symptoms. Patients with abnormal HADS anxiety scores were significantly more frequently rehospitalized (Odds ratio 1.9; p = 0.028) and also more frequently reported pain symptoms (Odds ratio 2.0; p = 0.019). These results demonstrate the persistence of depressive symptoms and the frequent utilization of health care in internal medicine inpatients with psychiatric disorders in the first year after hospital discharge.
