Chronic kidney disease (CKD) affects an estimated 37 million Americans, yet most cases go undiagnosed until the disease has significantly progressed. A urine albumin-to-creatinine ratio (uACR) test can detect kidney damage years before a decline in the estimated glomerular filtration rate (eGFR), but it remains underutilized.
In the first episode of Beyond the Silo: Integrated Care Across the CRM Continuum, a podcast series from The American Journal of Managed Care®, Marc P. Bonaca, MD, MPH, moderates a discussion with Josephine Harrington, MD, on why uACR has not yet become a standard of care, how CKD fits into the broader cardio-renal-metabolic (CRM) disease continuum, and what changes are needed across specialties, systems, and workflows.
Bonaca is a cardiologist and vascular medicine specialist at the University of Colorado Anschutz and the executive director of CPC Clinical Research. Harrington is also a cardiologist, specializing in advanced heart failure and transplant cardiology at UCHealth’s Heart and Vascular Center at the University of Colorado Hospital.
Throughout the conversation, they emphasize that CKD is an early integral part of the CRM continuum, as it is both a driver and consequence of cardiovascular risk, with uACR elevation often appearing before eGFR decline and signaling increased risk even at mild levels. Despite strong guideline support, uACR screening remains underused due to structural barriers. Therefore, the experts explained that the primary barrier is not the test itself but the lack of streamlined workflows that make screening routine and results actionable without adding clinician burden.
They concluded that early detection is critical because it enables the timely use of therapies such as SGLT2 inhibitors, glucagon-like peptide-1 receptor agonists, and finerenone, which improve outcomes. To close the gap, the experts noted that uACR should be treated as a routine vital sign for cardiometabolic risk and embedded into health system quality metrics to ensure consistent, accountable use.
