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

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

  Intra-class correlation (%) Variance estimate Standard error P value
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
  1. Geographic regions: 13; Facilities: 61; Patients:21,052
  2. 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
