The Swiss Transplant Cohort Study: Implications for Transplant Infectious Diseases Research.

The longitudinal, nationwide Swiss Transplant Cohort Study (STCS) follows > 92% of all transplant recipients with comprehensive data collection tailored to overall and organ-specific transplant outcomes. Transplant infectious disease events are assembled under the auspices of transplant ID specialists using common definitions. With over 6000 active patients and a median follow-up exceeding 6 years, the cohort offers a unique platform for understanding real-world epidemiology in transplanted patients. Beyond observational analysis, the STCS supports randomized controlled trials to address specific research questions. This overview highlights the achievements of the STCS and explores its future directions.
