Geographic and facility variation in initial use of non-tunneled catheters for incident maintenance hemodialysis patients

Table 2 Multi-level model analysis of the unadjusted and adjusted variation at the facility and geographic-level for the initiation of dialysis with a non-tunneled temporary hemodialysis catheter

	Intra-class correlation (%)	Variance estimate	Standard error	P value
Unadjusted
Facility	43.9	1.44	0.30	<0.0001
Geography	21.8	0.72	0.43	0.1
Fully adjusted
Facility	40.0	1.32	0.30	<0.0001
Geography	34.1	1.12	0.68	0.1

Geographic regions: 13; Facilities: 61; Patients:21,052
Adjusted for patient-level variables: age, sex, co-morbidities (CVA, angina, PVD, MI, Cancer, Pulmonary edema, COPD, DM, HTN, serious illness, CABG), body-mass index, laboratory values, distance from dialysis facility, cause of ESRD, race, eGFR at dialysis initiation and facility-level variables: % transplant facility, % peritoneal dialysis facility, and mean facility laboratory values, mean eGFR at dialysis initiation, mean distance from facility, mean facility size
