[Patients with ICD-10 disorders F3 and F4 in psychiatric and psychosomatic in-patient units - who is treated where? : Allocation features from the PfAD study]. / Patienten mit Störungen nach ICD-10 F3 und F4 in Psychiatrie und Psychosomatik ­ wer wird wo behandelt? : Merkmale der Zuweisung aus der PfAD-Studie.

BACKGROUND: In Germany, in-patient treatment of patients with depressive, neurotic, anxiety, and somatoform disorders (ICD-10 F3, F4) is carried out in different settings in psychiatry and psychosomatics. Which patient characteristics determine referral to one or the other specialty is a crucial question in mental health policy and is a matter of ongoing controversy. However, comparative data on patient populations are widely lacking. METHODS: In the study of Treatment Pathways of Patients with Anxiety and Depression (PfAD study), a total of 320 patients with ICD-10 F3/F4 clinical diagnoses were consecutively recruited from four treatment settings (psychiatric depression ward, psychiatric crisis intervention ward, psychiatric day hospitals, or psychosomatic hospital units; 80 participants per setting) and investigated. RESULTS: In all treatment settings, patients with considerable severity of illness and chronicity were treated. Female gender, higher education, and higher income predicted referral to psychosomatic units; male gender, transfer from another hospital or emergency hospitalization, co-morbidity with a personality disorder, higher general psychiatric co-morbidity, and danger to self at admission predicted referral to psychiatric unit. Patients in psychosomatic units had neither more psychosomatic disorders nor more somatic problems. DISCUSSION: There is considerable overlap between the clientele of psychiatric and psychosomatic units. Referral and allocation appears to be determined by aspects of severity and social status.
