Proportion who started dialysis as an inpatient, % (95% CI) | 38.8 (35.2-42.4) | 42.0 (38.4-45.6) | 40.6 (37.1-44.3) | 47.6 (44.1-51.2) | 45.2 (41.9-48.5) | .001 |
Proportion whose last eGFR was >10.5 mL/min/1.73 m2,a % (95% CI) | 25.6 (22.4-29.0) | 21.2 (18.3-24.3) | 20.1 (17.3-23.2) | 17.3 (14.7-20.1) | 14.7 (12.4-17.2) | <.001 |
Last eGFR before dialysis (mL/min/1.73 m2)a, mean (95% CI) | 9.3 (8.8-9.9) | 8.6 (8.3-8.9) | 8.4 (8.1-8.8) | 8.2 (7.9-8.4) | 7.7 (7.5-8.0) | <.001 |
Proportion whose last eGFR was <6 mL/min/1.73 m2,a % (95% CI) | 21.5 (18.5-24.8) | 22.8 (19.8-26.1) | 23.5 (20.5-26.8) | 26.6 (23.5-29.8) | 29.9 (26.9-33.1) | <.001 |
Note. A total of 108 patients were excluded because their most recent serum creatinine measurement was done more than 30 days prior to RRT, or they had no prior serum creatinine measurement. CI = confidence interval; eGFR = estimated glomerular filtration rate.
Among incident dialysis patients were those who were followed by a nephrologist for more than 90 days and had a serum creatinine measurement taken 30 days or less before dialysis initiation.
