Background and objectives: Introducing fixed fees for inpatient hospital care has raised fears of a negative influence on treatment quality. To address these concerns, an external quality assurance was implemented. The results of the quality indicators should indicate changes in the quality of inpatient care between 2004 and 2008.
Methods: On the basis of the evaluation data delivered by the Federal Quality Assurance Agency, quality indicators with similar results of at least 3 subsequent years were included. A trend was identified with linear regression as well as with a constant change in the results. 204 quality indicators of 19 health care sectors of 6 diagnosis groups were included.
Results: Half of the quality indicators showed a particularly striking quality improvement in the categories "indication" and "process". The lowest number of quality indicators with a quality improvement occurred in the cardiac surgery. To this diagnosis group also belong 13 of the 18 quality indicators with deterioration. Sixteen of the 18 quality indicators rank among the category "result".
Conclusion: The quality of inpatient care improved substantially from 2004 through 2008, measured against the quality indicators of the external comparable quality assurance. This corresponds to other analyses of a similar time period in Germany of the same or different data sources. Those analyses showed additionally that the subjective perceptions of clinicians and of nursing staff are significantly worse.
