Table 2.

Multilevel models of cognitive, motor, and total functional status ratings. Panel 1 shows 2-level patient-facility. Panel 2 shows patient-region. Panel 3 shows 3-level model of patient-facility-region. Covariate models include patient level demographic and clinical factors.

Panel 1: Two-Level Model: Patients within Facilities
	ICC (%)- Null Model	ICC (%)– With Covariates*
Cognition at Discharge	8.5 %	8.7 %
Motor at Discharge	5.9 %	9.5 %
Total Function Rating	6.2 %	8.8 %
Panel 2: Two-Level Model: Patient within Hospital Referral Regions (HRR)
	ICC - Null Model	ICC – With Covariates*
Cognition at Discharge	4.4 %	4.3 %
Motor at Discharge	3.7 %	4.3 %
Total Function Rating	3.7 %	3.8 %
Panel 3: Three-Level: Patients within Facilities within Regions
	ICC - Null Model	ICC– With Covariates*
Cognition at Discharge	HRR = 0.98 % Facility = 7.5 %	HRR = 0.95 % Facility = 7.8 %
Motor at Discharge	HRR = 1.6 % Facility = 4.3 %	HRR = 0.78 % Facility = 8.7 %
Total Function Rating	HRR = 1.4 % Facility = 4.8 %	HRR = 0.49 % Facility = 8.3 %

FIM = function rating from the Inpatient Rehabilitation Facility-Patient Assessment Instrument (IRF-PAI)

ICC = Intraclass correlation coefficient

^*Adjusted for age, gender, race, admission function rating, comorbidity, and length of stay
