Background: The indication for a mitral valve intervention is an important patient-relevant parameter for the assessment of process quality and the comparison of healthcare providers. In this article, we describe the development of a corresponding quality indicator for an external hospital quality assurance (QA) procedure in Germany.

Methods: An expert panel was set up by the aQua Institute to assist with the development of a QA procedure for mitral valve interventions and the associated quality indicators. In a comprehensive, systematic literature and evidence research, the American and European guidelines were identified as the best evidence available. Especially the more current American guideline formed the basis on which a quality indicator dealing with the correct indication for a mitral valve intervention was developed.

Results: The developed quality indicator assesses the proportion of patients for whom an indication for a mitral valve intervention was determined in compliance with guideline recommendations. The indicator differentiates between surgical and catheter-based procedures. To determine whether or not the indication was correct, different medical parameters are included, such as, for example, type of mitral valve defect, etiology of the disease, severity of symptoms, valve morphology (e. g., mitral valve area), valve hemodynamics and comorbidity, which healthcare providers have to document.

Conclusion: The documentation for the developed quality indicator is considerable. Nonetheless, its relevance is undeniable because it allows the user to determine whether a surgical or catheter-based mitral valve intervention was necessary and performed according to guideline recommendations. In the first year of its implementation, this indicator should be evaluated for further improvement and simplification of assessment.
