#5772 ESTIMATING CKD PREVALENCE AND INCIDENCE USING CROSS-SECTIONAL GERMAN CLAIMS DATA IN PERSONS AGED 70+

Abstract Background and Aims Little is known about trends over time anticipated improvements in CKD diagnosis after the implementation of Kidney Disease – Improving Global Outcomes (KDIGO) guidelines 2012. We investigated prevalence incidence using claims data persons aged 70+. Method assessed biennially cross-sectional German health insurance fund “AOK Nordost” for 70+ between 2012 2018. Data are available n = 62,200 per year were sampled equally distributed five age strata (70-74, 75–79, 80–84, 85–89, ≥90) sex. estimated 2012, 2014, 2016, 2018 in- outpatient ICD-10 diagnoses (N18.3, N18.4, N18.5, N18.8, N18.9, N19). Incidence was defined as prevalent cases without a four quarters preceding their first all at risk (i.e., who not respective previous year). Results shown total (standardized by sex nationwide demographic distributions year) well stratified Cochran-Armitage test applied to from 2012–2018. Claims data-based showed significant constant increase 0.18 0.26 (p <0.001). This trend consistent among (Figure 1).
