Table 5 Adjusted associations between facility characteristics and less favorable facility target weight measure score (>75th percentile)^a,b

Characteristic	Adjusted OR (95% CI)
Geographic region
West	1.00 (reference)
Midwest	2.33 (1.61–3.37)
South	2.68 (1.91–3.77)
Northeast	1.34 (0.88–2.02)
Monthly facility size (number of patients)
≤ 25	1.93 (0.81–4.56)
26–50	1.86 (0.91–3.77)
51–100	1.51 (0.91–3.80)
≥ 101	1.00 (reference)
Household income > median zip code income ($)^c	1.20 (0.96–1.50)
Age (per 10 years)	1.00 (1.00–1.01)
Black race >50% of facility patients	2.34 (1.78–3.07)
Hispanic ethnicity >25% of facility patients	1.45 (1.06–1.99)
Heart failure balance >25% of facility patients	0.79 (0.63–1.00)
Prescribed TT <240 min in >50% of facility patients	1.62 (1.15–2.28)
Prescribed UF rate ≥ 13 mL/h/kg in >33% of facility patients	1.31 (0.91–1.88)

^aFacility N = 1874. The multivariable binary logistic regression model with a dependent outcome of annual target weight measure score ≤ 75th percentile vs. >75th percentile was adjusted for geographic region (midwest, south, northeast vs. west), unit size (≤25, 26–50, 51–100 vs. ≥101 patients), household income (≤ vs. > median zip code income), age (per 10 years), black race (≤50% vs. >50% of facility patients), Hispanic ethnicity (≤25% vs. >25% of facility patients), heart failure balance (≤25% vs. >25% of facility patients), prescribed TT <240 min (≤50% vs. >50% of facility patients), and prescribed UF rate ≥ 13 mL/h/kg (≤33% vs. >33% of facility patients)
^bThe 75th percentile represents 32.9% of facility patients with post-dialysis weight ≥ 1 kg above or below the prescribed target weight. Measure 75th percentile reflects the 75th percentile of the annual measure score, and facility data reflect the January 2012 cohort data
^c Mean of the median household incomes. Income data was obtained from 2010 U.S. Census data based upon dialysis facility zip code
