Simplified data collection
“Klinrisk is very effective,” but requires follow-up by clinicians and health systems to implement its findings, commented Josef Coresh, MD, a professor of clinical epidemiology at Johns Hopkins Bloomberg, Baltimore. Dr. Coresh compared it with a free equation that estimates a person’s risk for a 40% drop in kidney function over the next 3 years developed by Dr. Tangri, Dr. Coresh, and many collaborators led by Morgan C. Grams, MD, PhD, of New York University that they published in 2022, and posted on a website of the CKD Prognosis Consortium.

The CKD Prognosis Consortium formula “takes a different approach” from Klinrisk. The commercial formula “is simpler, only using lab measures, and avoids inputs taken from physical examination such as systolic blood pressure and body mass index and health history data such as smoking, noted Dr. Coresh. He also speculated that “a commercial formula that must be paid for may counterintuitively result in better follow-up for making management changes if it uses some of the resources for education and system changes.”
Using data from multiple sources, like the CKD Prognosis Consortium equation, can create implementation challenges, said Dr. Tangri. “Lab results don’t vary much,” which makes Klinrisk “quite an improvement for implementation. It’s easier to implement.”
Other findings from the newest validation study that Dr. Tangri presented were that the people studied with Klinrisk scores in the top 10% had, over the next 2 years of follow-up and compared with people in the bottom half for Klinrisk staging, a 3- to 5-fold higher rate of all-cause medical costs, a 13-30-fold increase in CKD-related costs, and a 5- to 10-fold increase in hospitalizations and ED visits.
Early identification of CKD and early initiation of intensified treatment for high-risk patients can reduce the rate of progression to dialysis, reduce hospitalizations for heart failure, and lower the cost of care, Dr. Tangri said.
The validation study in 4.6 million Americans was sponsored by Boehringer Ingelheim. Dr. Tangri founded and has an ownership interest in Klinrisk. He has also received honoraria from, has ownership interests in, and has been a consultant to multiple pharmaceutical companies. Dr. Coresh had no disclosures.
