    As mentioned in the August NAACCR Narrative, NAACCR, SEER and NPCR have been collaborating for many months regarding the true impact of the COVID-19 pandemic on completeness estimates for the 2020 diagnosis year. SEER completed an extensive analysis of the estimated impact of the COVID-19 pandemic on incidence. They notified their registries that they will be adjusting registry completeness estimates by 10.86% to account for the decrease in cases. Please see attached for an overview of the method and rationale.


    Both NPCR and NAACCR will analyze the 24-month submission data using several methods to determine possible adjustments to their completeness methods. All three organizations will continue to collaborate to ensure the best approach.
