The study aim was to assess prevalence and severity of CKD based on a population with type 1 diabetes receiving care at a large United States health system.<h4>Methods</h4>Type 1 diabetes was identified through the Providence health system electronic health records during 2013-2022. Prevalent CKD was defined cross-sectionally by ≥ 90-day persistence of estimated glomerular filtration rate (eGFR) < 60 mL/min/1.73 m², urine albumin-to-creatinine ratio ≥30 mg/g, or urine protein-to-creatinine ratio ≥0.15 g/g. Multivariable logistic regression models analyzed variable associations with CKD and severe kidney disease (Lancet regional health.
