In the German DRG system the funding of CL services is not ensured. The documentation of psychiatric comorbidity and CL care delivery is a pre-condition to the development of funding models for CL-services. A task force of several German psychosomatic associations (German College of Psychosomatic Medicine, German Society of Psychosomatic Medicine and Psychotherapy, General Medical Society for Psychotherapy) developed a new documentation form for CL-services (CL-BaDo). The pilot study explored the multicenter implementation of CL-BaDo and the use of the documentation form for quality management and cost calculation. Over a period of at least three months, participating CL-services documented all CL cases consecutively with the CL-BaDo. One site applied full electronic data processing. 2116 CL cases from eight psychosomatic CL-services were analysed. The CL-BaDo is a time-efficient, feasible and acceptable documentation form for CL-service delivery. The full electronic data processing enables networking with a hospital information system to produce higher data quality. The data of CL-BaDo can be used locally for quality management, development of management strategies and communication with consultants, as well as nationwide for health policy questions and research.
