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. 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. More detailed information on reference areas can be found at the following link: https://iqtig.org/das-iqtig/grundlagen/methodische-grundlagen.

Specialist note IQTIG It should be noted that this computational result may not be influenced exclusively by the respective institution. For example, the severity of illnesses or concomitant diseases of the patients have an impact on the result. 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. Further information on the adjustments made can be found in the description of the quality indicators at the following link: https://iqtig.org/qs-verfahren/.

Specialist note IQTIG This is a transparency measure. Transparency indicators do not meet the formal criteria of a quality indicator because they have no reference area and therefore do not trigger a structured dialogue. The results are independent and are not directly linked to a quality indicator. However, transparency indicators indicate essential quality aspects of the supply process and thus increase transparency and the information content.
