The structural, economic, and therapeutic long-term effects are described in this paper. The model project in the Steinburg district (Schleswig-Holstein) describes the developments between 2002 (index year) and 2020 that have developed through the regional budget. The article describes the situation and its specific changes in the first german model region. There is no comparable control group. In the observed period, the number of people treated was stable within a corridor that has been in the contract with the stakeholders. Care has shifted relevantly from fully inpatient to outpatient and day clinic treatment. The costs have remained stable and thus differ significantly from the overall increase in health care costs. New supply concepts could be implemented. The model projects described lead to setting-independent care and are suitable for standard care in a defined region. The model projects described lead to setting-independent care and are suitable for standard care in a defined region. The implementation of Inpatient-equivalent treatment (IET) is advocated. In the Munich IET-program about 50 % of the IET patients were admitted directly whereas 50 % were transferred from inpatient units. Data on the first N = 169 IET patients were used to compare patients being directly admitted with those who were transferred from inpatients units to IET. Patients admitted directly to IET more often had an affective disorder, had lower CGI scores, had better German language skills and were more often competitively employed. Most patients referred to IET from inpatient units (66 %) did not fulfil IET inclusion criteria during inpatient admission. Regarding IET duration there were no major differences between patients being directly admitted vs. those being transferred from inpatient units. Patients not fulfilling IET inclusio
