Table 2. Facility-Level Median Rate Ratios for Dialysis Use and Mortality.

Model	Median rate ratio
	Full cohort (N = 8695)		eGFR <15 mL/min/1.73 m2 cohort (n = 7225)
	Dialysis use	Mortality	Dialysis use	Mortality
Unadjusted	1.35	1.05	1.17	1.05
Adjusted for patient characteristics	1.42a	1.11b	1.25	1.12
Fully adjusted	1.40c	1.08d	1.23	1.08

Abbreviation: eGFR, estimated glomerular filtration rate.

^aModels were adjusted for patient age, sex, race/ethnicity, driving distance to the nearest US Department of Veterans Affairs (VA) facility, serum albumin level, eGFR at incident kidney failure, rate of eGFR decline, nephrology care, and the following comorbidities: cancer, chronic lung disease, liver disease, congestive heart failure, dementia, diabetes, ischemic heart disease, and peripheral vascular disease.

^bModels were adjusted for patient age, sex, race/ethnicity, driving distance to the nearest VA facility, co-payment, serum albumin level, eGFR at incident kidney failure, rate of eGFR decline, nephrology care, and the following comorbidities: cancer, chronic lung disease, liver disease, congestive heart failure, dementia, paralysis, ischemic heart disease, peripheral vascular disease, cerebrovascular disease, rheumatologic disease, nursing home residence, and number of hospitalizations in the year before incident kidney failure.

^cModels were adjusted for patient characteristics cited in note a and the following facility characteristics: facility complexity, Veterans Integrated Service Network (VISN) region, presence of outpatient dialysis unit, maximum dialysis unit capacity, and percent occupancy of dialysis unit.

^dModels were adjusted for patient characteristics cited in note b and the following facility characteristics: facility complexity, VISN region, presence of outpatient dialysis unit, maximum dialysis unit capacity, and percent occupancy of dialysis unit.
