The Wisconsin Allograft Recipient Database (WisARD) was initiated in 1984 and collects information on all solid organ transplants performed at the University of Wisconsin (UW). The UW transplant program is one of the most active programs in the US for kidney transplants (367 in 2016; more than 10,000 total), pancreas transplants (65 in 2016; more than 1,500 total) and liver transplants (nearly 2,400 total). Available data include pre-transplant details (e.g., cause of disease, duration of disease, comorbidities), immediate post-transplant data (e.g., all relevant medications, laboratory values and in-hospital events), and follow-up information (graft survival, hospitalizations, procedures and diagnoses). UW receives monthly laboratory values for most recipients (e.g., more than 500,000 serum creatinine measurements are available from kidney transplant recipients). WisARD has been an extremely productive resource for clinical research, with over 300 publications on a broad array of transplant-related issues (PMID: 30704880; 30574502; 26760571; 26566058). Dr. Brad Astor is the Director of Research in the Division of Nephrology, Department of Medicine, and works closely with investigators using data from WisARD.
