EURObservational Research Programme: a bibliometric assessment of its scientific output.

Aims: Given the lack of reliable observational data, a network of volunteer centres, and standardized methodological procedures, the European Society of Cardiology EURObservational Research Programme (EORP) was set up to provide a better understanding of real-world cardiovascular care and outcomes. We aimed to evaluate the scientific impact of EORP using a bibliometric approach.

Methods And Results: We collected data for each individual publication and for each individual journal with at least one EORP publication. Bibliometric indicators evaluating research performance were categorized into those evaluating EORP publications (publication-based indicators) and those assessing the journals where those papers were published (journal-based indicators). During the first ∼11 years since its inception, we found that EORP produced 189 publications, with most published in journals in the first quartile (60.9%) or the second quartile (33.5%) of the Web of Science Journal Citation Report. The total number of citations to EORP publications was 9630 (average citation per publication of 51, h-index of 54, and 29 EORP publications with ≥100 citations). Of EORP publications, 20 had an Altmetric Attention Score >50 and 9 had a score >100. A total of 52 EORP papers have been cited 65 times in ESC Clinical Practice Guidelines between 2013 and 2021.

Conclusion: EORP registries have contributed to impactful scientific knowledge. The high-quality metrics highlight the relevance of the EORP international cardiovascular registries to the academic community. Efforts are needed to support this, and other programmes aimed at delivering real-world evidence from independent patient data of cardiovascular care and outcomes across multiple geographies.
