Association of Site-Level Factors and Relative Percent Change in 30-Day Risk-Adjusted Readmission Rates Between 2009 and 2012

Site Factor	Estimate (95% CI), %	P Value
Percent of patients referred to a heart failure disease management program	−0.09 (−0.18 to −0.01)	.03
Percent ACE inhibitor/ARB for patients with LVSD	−0.27 (−0.63 to 0.09)	.14
Teaching site	3.54 (0.03 to 7.05)	.05

†Variables listed were chosen based on forward selection to be included in multivariable linear regression model. Each site’s relative risk-adjusted 30-day readmission rate was used as the dependent variable in the model.
