To evaluate the cumulative summation technique (CUSUM) as a continuously updatable, risk-adjusted tool for detecting clinically relevant performance shifts in organ transplant centers.
Analyzed Scientific Registry of Transplant Recipients records for adult kidney and liver transplant procedures performed between January 1997 and December 2001.
Used logistic regression models to adjust for risk and predict 1-year graft failure in kidney recipients and 1-year mortality in liver recipients.
Constructed center-specific risk-adjusted CUSUM charts and compared findings against the Organ Procurement and Transplantation Network (OPTN) semi-annual surveillance method.
Among 258 kidney transplant centers performing 59,650 transplants with a 9.2% 1-year graft failure rate, CUSUM detected significantly improving performance at 92 centers and declining performance at 52 centers.
Among 114 liver transplant centers performing 18,277 procedures with a 13.9% 1-year mortality rate, CUSUM identified 48 improving centers and 24 declining centers.
CUSUM captured the majority of low-performing centers flagged by the conventional OPTN semi-annual method, detecting 20 of 22 kidney centers and 8 of 11 liver centers.
