Background: The Institute of Quality Assurance and Transparency in Health Care (IQTIG) was commissioned by the Federal Joint Committee (G-BA) to include the patient perspective in the quality assurance programme for patients undergoing percutaneous cardiac intervention (PCI) and coronary angiography ("QS PCI"). This article describes both the development methodology and the survey-based quality indicators., Methods: On the basis of a systematic literature research, focus groups with patients, interviews with doctors and an expert group meeting, quality criteria were defined which were relevant to patients. These criteria were translated into PREMs and PROMs. The questionnaires were subjected to a two-phase pretest. Quality indicators were composed by aggregating the items., Results: Altogether, 12 topic areas were identified which are relevant to patients receiving percutaneous cardiac intervention or coronary angiography. Here, communication and interaction were of high importance. In addition, information before, during and after the procedure was very relevant, and, likewise, the health care professionals' interaction with patients. Also, symptoms and treatment effects were important. In accordance with the defined topics, 19 quality indicators were developed which can display quality of health care from the patients' perspective., Conclusion: The development of PREMs and PROMs expanded the quality assurance programme "QS PCI" to include significant dimensions relevant to patients, which can, therefore, provide valuable information to improve patient-centred care., (Copyright © 2023.
