Background Graft loss, a critically important outcome for transplant recipients, is variably defined and measured, and incompletely reported in trials. We convened a consensus workshop on establishing a core outcome measure for graft loss for all trials in kidney transplantation. Methods Twenty-five kidney transplant recipients/caregivers and 33 health professionals from 8 countries participated. Transcripts were analyzed thematically. Results Five themes were identified. Graft loss as a continuum conceptualizes graft loss as a process, but requiring an endpoint defined as a discrete event. In defining an event with precision and accuracy, loss of graft function requiring chronic dialysis (minimum, 90 days) provided an objective and practical definition; retransplant would capture preemptive transplantation; relisting was readily measured but would overestimate graft loss; and allograft nephrectomy was redundant in being preceded by dialysis. However, the thresholds for renal replacement therapy varied. Conservative management was regarded as too ambiguous and complex to use routinely. Distinguishing death-censored graft loss would ensure clarity and meaningfulness in interpreting results. Consistent reporting for decision making by specifying time points and metrics (ie time to event) was suggested. Ease of ascertainment and data collection of the outcome from registries could support use of registry data to efficiently extend follow-up of trial participants. Conclusions A practical and meaningful core outcome measure for graft loss may be defined as chronic dialysis or retransplant, and distinguished from loss due to death. Consistent reporting of graft loss using standardized metrics and time points may improve the contribution of trials to decision making in kidney transplantation.
