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 care process and thus increase transparency and the information content.

It should be noted that this computational result may not be influenced exclusively by the respective institution. So e.g. the severity of illness or concomitant illnesses of the patients have an influence on the result.

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, since 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. 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.

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 sets a benchmark for the assessment 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 faulty documentation, medical specificity of the patient collective or individual cases. The assessment of quality is carried out within the framework of the defined procedure in the comments procedure. More information on reference areas can be found at the following link: https://iqtig.org/das-iqtig/grundlagen/methodische-grundlagen.

Specialist note IQTIG Zu beachten ist, dass dieses rechnerische Ergebnis unter Umständen nicht ausschließlich durch die jeweilige Einrichtung beeinflusst wird. So können z.B. die Erkrankungsschwere oder Begleiterkrankungen der Patientinnen und Patienten einen Einfluss auf das Ergebnis haben. Der Referenzbereich gibt an, in welchem Bereich die Ergebnisse eines Indikators als unauffällig bewertet werden. Eine Einrichtung mit einem Ergebnis außerhalb des Referenzbereichs ist zunächst rechnerisch auffällig, dies zieht üblicherweise eine Analyse im Strukturierten Dialog nach sich. Es ist zu beachten, dass ein Indikatorergebnis außerhalb des Referenzbereichs nicht gleichbedeutend ist mit einer mangelnden Qualität der Einrichtung in dem hier betrachteten Qualitätsaspekt. Die Abweichung kann auch z.B. auf eine fehlerhafte Dokumentation oder auf Einzelfälle zurückführbar sein. Die Bewertung der Qualität wird im Rahmen des Strukturierten Dialogs mit den Einrichtungen vorgenommen. Die Ergebnisse dieses Qualitätsindikators sind aufgrund von Anpassungen der Rechenregel des Indikators nur eingeschränkt mit den Vorjahresergebnissen vergleichbar. Nähere Informationen zu den vorgenommenen Anpassungen können der Beschreibung der Qualitätsindikatoren unter folgendem Link entnommen werden: https://iqtig.org/qs-verfahren/.
