Abstract
Background: We explore how area deprivation index (ADI), a national ranking of neighbourhood sociodemographic disadvantage is associated with chronic kidney disease (CKD) screening and development among patients with newly diagnosed hypertension (HTN) or type 2 diabetes (T2DM).
Methods: Patients (n=235 208) with a new HTN or T2DM diagnosis between 2015 and 2018 in a large healthcare system were followed for 3 years to evaluate CKD screening (one estimated glomerular filtration rate and urinary albumin-to-creatine ratio) and CKD development. Multivariable logistic regression models evaluated associations between ADI quintiles with CKD screening and diagnosis.
Results: Most patients were white (57%) females (55%) with HTN (65%). Few were screened in the first year after diagnosis (17%) and 9% developed CKD within 3 years. The odds of patients being screened were 54% greater (OR 1.54; 95% CI 1.48 to 1.60) and 146% greater (OR 2.46; 95% CI 2.19 to 2.76) for developing CKD for most deprived compared with the least deprived.
Conclusions: Patients with high ADI were more likely to be screened and almost twice as likely to develop CKD compared with the least deprived. Results highlight the importance of systematic health record data collection in large healthcare systems to evaluate social factors with health outcomes.
