Specialist note IQTIG The reference range indicates the results at which a facility can be assumed to provide good quality of care, although deviations are possible. The reference range thus establishes a benchmark for the evaluation of facilities. A result outside the reference range is initially considered conspicuous. This usually entails an analysis by means of a statement procedure. It should be noted that a quality result outside the reference range is not synonymous with a lack of quality of the facility in the quality aspect considered here. The deviation can also be due, for example, to incorrect documentation, medical specificity of the patient collective or individual cases. The evaluation of quality is carried out within the framework of the defined procedure in the comments procedure.

Specialist note IQTIG Although key figures represent quality, their results do not enable a direct assessment of the quality of care (due to the lack of a reference range) and they are also not suitable for direct quality comparisons (due to the lack of mathematical adjustment). However, they are usually published in direct connection with a quality indicator, the results of which are supplemented by the key figures (imputed and supplementary key figures). They therefore contribute to increasing the comprehensibility of the quality results. The transparency indicators, which are to be distinguished from these, represent aspects of care for which there are no quality indicators, but which are nevertheless important for presenting the quality of care. Further information on key figures can be found at the following link: https://iqtig.org/veroeffentlichungen/kennzahlenkonzept/. Due to adjustments to the calculation rule or inclusion/exclusion criteria for the cases to be documented in the QA procedure, the quality result is only comparable with the previous year's results to a limited extent. Further information on the adjustments made can be found in the description of the quality indicators and key figures at the following link: https://iqtig.org/qs-verfahren/.

Specialist note IQTIG Risk adjustment aims to compensate for the different patient structure in different facilities. Ideally, this leads to a fair comparison of the different facilities, since patients have individual risk factors (such as concomitant diseases) that systematically influence the quality outcome, without it being possible to attribute responsibility for e.g. resulting more frequent complications to one facility. With the help of risk adjustment, the quality outcome of, for example, an institution with many high-risk cases can be statistically compared more fairly with the quality outcome of an institution with many low-risk cases. More information on risk adjustment can be found at the following link: https://iqtig.org/das-iqtig/grundlagen/methodische-grundlagen. The reference range indicates the results at which a facility can be assumed to provide good quality of care, although deviations are possible. The reference range thus establishes a benchmark for the evaluation of facilities. A result outside the reference range is initially considered suspicious. This usually entails an analysis by means of a statement procedure. It should be noted that a quality result outside the reference range is not synonymous with a lack of quality of the facility in the quality aspect considered here.
