German Inpatient Quality Indicators (G-IQI) is the most comprehensive
system of quality indicators based on administrative data. G-IQI
allows a disease-specific monitoring of inpatient care in acute care
hospitals. On the one hand, the indicators are designed to provide
medically meaningful figures on hospital performance and outcomes for
external users. On the other hand, the indicators serve as a tool for
internal quality management and quality improvement in hospital care.
The indicators may help hospitals to identify potential for
improvement by comparing their own results with national figures. The
indicators serve as triggers for peer reviews or morbidity and
mortality conferences. Thus, the use of the indicators is essential
to detect medical errors and to find potential for improvement.
The national reference values of the indicators allow hospitals to assess their own results as compared to national figures. Beyond that, the national reference values provide a comprehensive analysis of inpatient care in German acute care hospitals. This analysis covers various figures, which are not published by any other statistics. Hence, the national reference values complement other systems of health care reporting.
The present working paper contains the German national reference values of the year 2016 for the G-IQI version 5.2. Reference values were calculated by using the microdata of the national hospital statistics database (DRG statistics) and are displayed for each indicator. The technical specifications of the indicators are attached in the appendix of this paper and refer to the German coding systems valid in 2019. The G-IQI version 5.2 represents a modification and expansion of the previous version 5.1. The present G-IQI version 5.2 captures 51.5% of all inpatient cases and 78.4% of all in-hospital deaths. Thereby, the G-IQI version 5.2 achieves one of the highest coverage among available quality indicator systems.
