Within the Department of Anesthesiology and Intensive Care Medicine CCM/CVK at Charité- University Medicine Berlin, the systematic evaluation of quality-related process indicators is standard practice. These are based on the intensive care quality indicators of the German Interdisciplinary Association for Intensive Care and Emergency Medicine (DIVI). These process-based indicators are to be correlated with the examination of outcome indicators from routine data transmission in accordance with §21 data record (e.g., 30-day readmission rate, mortality, infection rate, length of stay) and economic parameters of treatment from controlling data (Diagnosis Related Groups revenue, case costs). The §21 data record describes a standardized data format that hospitals are required to transmit to the Institute for the Hospital Remuneration System (InEK) in accordance with § 21 (4) and (5) Act on Fees for Full and Partial Inpatient Hospital Services (Hospital Fees Act - KHEntgG). Data on standard clinical care from the Charité hospital systems will be used.
