How does research output and impact in medical informatics vary among EU member states? - A bibliometric analysis.

Objectives: This study evaluates how research output and impact in medical informatics vary among EU member states before and during the COVID-19 pandemic by analyzing publication volume, impact metrics, collaboration patterns, and open-access trends. It seeks to identify regional disparities, highlight key research themes, and provide insights for researchers, the public, and policymakers to promote equitable access, collaboration, and investment in medical informatics across the EU.

Methods: A bibliometric analysis was performed using Clarivate Web of Science and InCites databases, encompassing 6,620 articles from 47 medical informatics journals published between 2018 and 2022. Metrics such as cumulative impact factors, article counts, and collaboration trends were analyzed.

Results: Our analysis identified substantial regional disparities in research output and impact. Western European countries, including Germany, the Netherlands, and Spain, consistently led in article volume and cumulative impact factors, while Eastern European countries showed lower engagement. Collaboration metrics revealed that 66 % of publications involved international partnerships, showcasing strong cross-border cooperation within the EU.

Conclusions: This study highlights the uneven distribution of research productivity in medical informatics across the EU. The findings underline the importance of international partnerships and equitable access to research in advancing medical informatics and addressing evolving healthcare challenges.
