National Collaborations

Swiss Severe Asthma Registry: Collaborating Main Centers: Inselspital Bern, KSSG (Cantonal Hospital St.Gallen), University Hospital Zürich, Cantonal Hospital Graubünden, and EOC (Ente Ospedaliero cantonale all 4 hospitals), HUG (University Hospital Geneva), HVS (Cantonal Hospital Valais), CHUV (University Hospital Lausanne). Furthermore smaller Hospitals and pneumologists in a private practice setting (Total Number or participating centers 46).

Swiss COPD Cohort: A total number of 25 centers participate in this trial.

RECUT: A total of 89 general practitioners and pneumologists are participating in this trial.

Consortium KSA KSSG EOC KSB The consortium (KSBL=Cantonal Hospital Baselland, KSSG=Cantonal Hospital St.Gallen, KSA=Cantonal Hospital Aarau, EOC=Ente Ospedaliero Cantonale) was established in 2018 and set its first aim as the acquisition of funding from the SPHN in the form of a Driver Project in personalized health using interoperable and exchangeable health-related data. The consortium therefore has a solid, well-established and collaborative partnership that has continuously been developed over the past four years. We are currently conducting several projects within the consortium, including a prospective observational cohort study (Swiss Severe Asthma Registry), various retrospective cohort observational studies and two randomized clinical trials with Covid-19 patients.

IT – Research collaboration We integrated a process of data extraction through SQL queries directly into Data Marts that now allows us to extract a larger amount of structured data, which serve as a data quality control set with which to test specificity/sensitivity/ accuracy of the software searches for the unstructured data.
The collaboration between the research and the IT department allowed to integrate new systems and software that make data collection more efficient and ensure higher quality of research processes. (eg. Rstudio pro for data analysis, REDcap for data collection and analysis, Confluence for project management, e-Health for data )

Various partners from the pharmaceutical industry: GSK, Novartis, Astra Zeneca, Böhringer Ingelheim, Sanofi, Teva-Mepha, OM Pharma, Bayer, Mundipharma, Swica AG

PPCR: The core mission of Principles and Practice of Clinical Research (PPCR) Program is to offer training in clinical research and create a global network of clinical researchers. The program is taught by experienced faculty members from Harvard University. The faculty and staff involved in this innovative educational method are internationally recognized for their teaching in clinical research. Prof. Leuppi sponsored and supported the training of Giorgia Lüthi-Corridori who after graduation in 2021 had the honour to be selected as a teaching assistant. The PPCR network consists of high-profile doctors and researchers from all over the world characterised by a spirit of collaboration and support.
