Specialist note IQTIG Risk adjustment aims to compensate for the different patient structures 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 one facility being held responsible for, for example, more frequent complications as a result. With the help of risk adjustment, the quality outcome of, for example, a facility with many high-risk cases can be statistically compared more fairly with the quality outcome of a facility 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 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.

Specialist note IQTIG Although indicators represent quality, their results do not allow a direct assessment of the quality of care (due to the lack of a reference range) and they are 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 result of which is supplemented by the indicator values (imputed and supplementary indicators). They thus contribute to an increase in 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 the presentation of the quality of care. More detailed information on indicators can be found at the following link: https://iqtig.org/veroeffentlichungen/kennzahlenkonzept.

The choice of system for defibrillator implantation is assessed according to the current guidelines on pacemaker and cardiac resynchronisation therapy, on the diagnosis and treatment of heart failure, and on the management of patients with ventricular arrhythmias and the prevention of sudden cardiac death of the European Society of Cardiology (Brignole et al. 2013, Glikson et al. 2021, McDonagh 2021, Priori et al. 2015). In individual cases, there may be justified deviations from the guidelines if defibrillators are implanted, e.g. as part of studies or when testing new procedures. - Brignole, M: Auricchio, A: Baron-Esquivias, G: Bordachar, P: Boriani, G: Breithardt, O-A: et al.

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. 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 noticeable in terms of calculation, 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 with 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 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. This indicator is a so-called quality index. This means that several measurements are evaluated per treatment case and that not only cases with a defibrillator implantation but also cases with a revision, a system change or an explantation of the defibrillator are considered. The aim is to consider an increased number of measurements and thus to reduce the number of cases prevalence problem (Heller 2010). If the number of cases is low at the site level, there is a risk that computational abnormalities arise systematically (randomly) from a few individual cases. 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 noticeable in terms of calculation, 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.
