Background: Fast glomerular filtration rate (GFR) decline is associated with adverse outcomes, but the associated risk factors among patients without chronic kidney disease (CKD) are not well defined. Methods: From a primary care registry of 37,796, we identified 2219 (6%) adults with at least three estimated (e)GFR values and a baseline eGFR between 60 and 119 ml/min/1.73 m2 during an observation period of 8 years. We defined fast GFR decline as CloseSPigtSPi 5 ml/min/1.73 m2 per year. The outcome measure was incident CKD (eGFR OpenSPiltSPi 60 ml/min/1.73 m2). Clinical and demographic characteristics were compared using Chi-square and independent-samples t tests. Results: Older age, African-American race, unmarried status, hypertension and type 2 diabetes were more common in both fast decliners and those who developed incident CKD (p OpenSPiltSPi 0.0001 to OpenSPiltSPi 0.05). Lower neighborhood socioeconomic status, current smoking and baseline eGFR 90–119 ml/min/1.73 m2 were associated with fast decline (p OpenSPiltSPi 0.01), while baseline eGFR 60–74 ml/min/1.73 m2 with incident CKD (p OpenSPiltSPi 0.05). In multivariate regression models, among fast decliners with mildly reduced baseline eGFR (60–89 ml/min/1.73 m2), older age was significantly associated with incident CKD [odds ratio (OR) 1.04; 95% CI 1.01–1.08], and among those with normal baseline eGFR (≥ 90–119 ml/min/1.73 m2), type 2 diabetes was significantly associated with incident CKD (OR 3.83; 95% CI 1.35–10.89). Conclusions: Among primary care patients without CKD, GFR is checked infrequently. We have identified patients at high risk of progressive CKD, in whom we suggest a closer monitoring of renal function.
