Comparisons of percentage of facility patients with UF rates >13 ml/h per kilogram by the CMS criteria versus percentage of facility patients with UF rates ≥13 ml/h per kilogram by the KCQA criteria were made using paired t tests. P values for all comparisons were <0.001. CMS, Centers for Medicare and Medicaid Services; KCQA, Kidney Care Quality Alliance; TT, treatment time; UF, ultrafiltration; Q1, quartile 1, Q3, quartile 3; —, no annual calculation per CMS measure criteria.
