Transatlantic Claims Study
GermanVasc is collaborating with the Department of Healthcare Policy and Research at the Weill Cornell College in New York City, USA. Under the project lead of C.-A. Behrendt, health insurance claims data is analysed to conduct comparative outcomes research in cardiovascular medicine.

GermanVasc is founding member of the International Consortium of Vascular Registries (ICVR). The ICVR was launched in 2014 with the goal to establish a collaborative platform across registries to share data to improve the quality of vascular health care. Manuscripts regarding abdominal aortic aneurysms (AAA) and carotid artery stenosis were published by this collaboration recently. GermanVasc was coordinating two international modified Delphi-studies to find a consensual agreement on minimal recommendations for registries on chronic peripheral arterial occlusive disease (PAOD) and acute limb ischaemia (ALI).

Vascunet is a collaboration of vascular registries from Europe and Australasia, administered and partly funded by the European Society for Vascular Surgery (ESVS). It was founded in 1997 and several reports and eight original articles have been published so far. GermanVasc was recently coordinating an international comparison of amputation incidences for peripheral arterial disease and diabetes.

In 2017, the IDOMENEO Consortium was established and funded (3,57 million Euros) by the German Federal Joint Committee (G-BA)
to implement a data privacy compliant and data safety registry plattform for peripheral vascular diseases in Germany. Central aspects of this multimethodological and multistage study is the utilization of health-insurance claims and primary registry data to perform quality improvement and vascular research.

The RABATT study is a further development of the IDOMENEO study. RABATT aims to develop Big Data solutions and (deep) learning algorithms to be used in real-world-data. The study consortium will implement a risk score for patients with peripheral arterial disease (PAD) that can be used to predict the estimated course (e.g., amputation risk for endovascular versus open-surgical versus best-medical-treatment).

The Medical Device Epidemiology Network (MDEpiNet) is a global effort bringing together all parts of the medical device ecosystem to build a national medical device evaluation system. As a Public Private partnership, MDEpiNet is working to improve and integrate real-world data infrastructure, develop appropriate methodologies, and conduct studies to improve patient-centered outcomes for medical devices around the world. GermanVasc is founding member of this collaboration.
Since 2019, the GermanVasc group is developing a German chapter of the MDEpiNet in Hamburg. A first summit on real world evidence in cardiovascular medicine will be held November 1, 2019. Meeting website!

GermanVasc is well-experienced in health-services research and quality improvement using real-world-data. GermanVasc is aiming to implement an independent scientific infrastructure in Germany to improve the utilization of primary registry data (GermanVasc-Platform) and health insurance claims data in the field of vascular diseases.
