Prevalence of advanced chronic kidney disease (CKD) based on different criteria.
| Prevalence subpopulation definition | Users, n | VAa users with creatinine lab measurement within last 12 months (n=93,216), % (95% CI) | Total VA users (N=133,756), % (95% CI) |
| Total VA users with at least one creatinine measurement within the last 12 months | 93,216 | 100.0 (100-100) | 69.7 (69.4-69.9) |
| Veterans with ICD-10b code N18.4 or N18.5 within last 12 months | 1102 | 1.2 (1.1-1.3) | 0.8 (0.8-0.9) |
| Veterans with index eGFRc <30 | 1391 | 1.5 (1.4-1.6) | 1.0 (1.0-1.1) |
| Veterans with index eGFR <30 and 90 days prior eGFR <60 | 1346 | 1.4 (1.4-1.5) | 1.0 (1.0-1.1) |
| Veterans with high risk of advanced CKD | 928 | 1.0 (0.9-1.1) | 0.7 (0.6-0.7) |
| Veterans with high and intermediate risk of advanced CKD | 1408 | 1.5 (1.4-1.6) | 1.1 (1.0-1.1) |
| Cumulative prevalence of advanced CKD (6 months) based on high- and intermediate-risk groups | 1840 | 2.0 (1.9-2.1) | 1.4 (1.3-1.4) |
