Specialist note IQTIG The reference range indicates the range in which the results of an indicator are assessed as normal. A facility with a result outside the reference range is initially computationally conspicuous, which usually results in an analysis in the structured dialog. It should be noted that an indicator result outside the reference range is not synonymous with a poor quality of the facility in the quality aspect considered here. The deviation can also e.g. be traceable to incorrect documentation or to individual cases. Quality is assessed in the context of the structured dialogue with the institutions.

Specialist note IQTIG This indicator is a risk-adjusted indicator. A risk adjustment compensates for the different composition of the patient groups from different institutions. This leads to a fairer comparison, as there are patient-related risk factors (such as comorbidities) that systematically influence the indicator result without an institution being responsible for e.g. the following more frequent complications can be attributed to it. For example, the indicator result of a facility with many high-risk cases can be compared more statistically with the result of a facility with many low-risk cases. The risk factors are compiled from patient characteristics that were classified as risk-relevant as part of the development of quality indicators and which can be practically documented. The reference range indicates the range in which the results of an indicator are assessed as normal. A facility with a result outside the reference range is initially computationally conspicuous, which usually results in an analysis in the structured dialog. It should be noted that an indicator result outside the reference range is not synonymous with a poor quality of the facility in the quality aspect considered here. The deviation can also e.g. be traceable to incorrect documentation or to individual cases. Quality is assessed in the context of the structured dialogue with the institutions. The results of this quality indicator can only be compared to the previous year's results to a limited extent due to adjustments to the calculation rule of the indicator.
