In contrast, when patient communications were delivered, 87.5% (n = 8) issued these communications exclusively after CKD-EPI 2021 implementation and the majority (6 of 8) reported using only one method of communication during delivery. When reporting on content inclusion, 64.3% (n = 28) of laboratories reported including concerns regarding previous race-based eGFR equations in communications with physicians/advanced practitioners, while only 16.7% (n = 18) of those who included this information did so with patients.</p><p><strong>Conclusions: </strong>Participants reported limited engagement in CKD-EPI 2021 laboratory-to-patient implementation communications as well as limited inclusion of additional stakeholder groups, as defined in the NKF-WG recommendations.
