New eGFR equation ‘less biased’ by age, kidney function; some disagree


 

Still room for improvement; app hopefully coming next year

Dr. Pottel and coauthors developed and validated the EKFC equation with data from 19,629 patients drawn from 13 cohorts. This included 11,251 patients from seven cohorts for development and internal validation, and 8378 from six cohorts for external validation. The EKFC effort received endorsement from the European Renal Association–European Dialysis and Transplant Association.

However, “We acknowledge that there is still room for improvement,” Dr. Pottel said.

Although the new report presents the EKFC equations (actually two slightly different equations depending on whether a patient’s serum creatinine is higher or lower than the relevant Q value), most potential users will likely find the equations easier to work with once they’re in an app form that allows someone to simply plug in age, sex, and serum creatinine level. That app currently doesn’t exist but is coming soon, promised Dr. Pottel.

“I hope to have an electronic tool by the beginning of 2021,” he said. “I have to find a programmer who can do this for me.”

The EKFC project has received no commercial funding. Dr. Pottel reported no relevant financial relationships. Dr. Levey has reported receiving research funding from AstraZeneca.
