Background Reactivation of BK polyomavirus (BKPyV) due to immunosuppression after renal transplantation can lead to allograft nephropathy (BKAN) or even allograft loss. Many transplant centers implement screening protocols in an attempt to detect BKPyV reactivation before progression to BKAN, although the frequency and duration of screening vary widely among centers. Methods The New England BK Consortium (NEBKCON), a collaboration of 12 transplant centers in the northeastern United States, has adopted a standard BKPyV screening protocol (screening monthly for the first 6 months followed by screening every 3 months until 2 years after transplantation). Participating members implemented this screening protocol at their centers, and later measured adherence to the protocol as part of a NEBKCON quality improvement project. This study retrospectively analyzes BKPyV-specific outcomes in association with adherence to this protocol. Results Six centers reported data on 472 subjects who received a renal transplant between January 2016 and December 2017. Adherence to the screening protocol during the first 12 months (7.1–76.7%, mean 56.1%) and 24 months (2.9–52.5%, mean 36.8%) after transplant varied between centers. Rates of BKPyV viremia (3.6–28.2%, mean 20.6%) as well as BKAN (0–4.5%, mean 3.2%) also varied among centers. Adherence to the screening protocol was associated with a decrease in the magnitude of the initial viral load detected (3.29 vs. 3.74 log10 copies/mL, P = 0.065), but was not associated with peak viral load (3.95 vs. 4.14 log10 copies/mL, P = 0.47), viremia duration (179 vs. 196 days, P = 0.74), or incidence of BKAN among viremic subjects (15.3 vs. 16.0%, P = 0.91). Conclusion Even with a uniform screening protocol for BKPyV in place, adherence to this protocol varied widely among centers. More research is needed to determine patient-level and center-level barriers to adherence, as well as to determine optimal screening practices to further reduce the incidence of BKAN.
