The France PCI registry: Design, methodology and key findings.

Background: Obstructive coronary artery disease is the main cause of death worldwide. By tracking events and gaining feedback on patient management, the most relevant information is provided to public health services to further improve prognosis.
Aims: To create an inclusive and accurate registry of all percutaneous coronary intervention (PCI) procedures performed in France, to assess and improve the quality of care and create research incentives. Also, to describe the methodology of this French national registry of interventional cardiology, and present early key findings.
Methods: The France PCI registry is a multicentre observational registry that includes consecutive patients undergoing coronary angiography and/or PCI. The registry was set up to provide online data analysis and structured reports of PCI activity, including process of care measures and assessment of risk-adjusted outcomes in all French PCI centres that are willing to participate. More than 150 baseline data items, describing demographic status, PCI indications and techniques, and in-hospital and 1-year outcomes, are captured into local reporting software by medical doctors and local research technicians, with subsequent encryption and internet transfer to central data servers. Annual activity reports and scoring tools available on the France PCI website enable users to benchmark and improve clinical practices. External validation and consistency assessments are performed, with feedback of data completeness to centres.
Results: Between 01 January 2014 and 31 December 2022, participating centres increased from six to 47, and collected 364,770 invasive coronary angiograms and 176,030 PCIs, including 54,049 non-ST-segment elevation myocardial infarction cases and 31,631 ST-segment elevation myocardial infarction cases. Fifteen studies stemming from the France PCI registry have already been published.
Conclusions: This fully electronic, daily updated, high-quality, low-cost, national registry is sustainable, and is now expanding. Merging with medicoeconomic databases and nested randomized scientific studies are ongoing steps to expand its scientific potential.
