Estimates from Logistic Regressions of Readmission Rates Comparing Related and Other Nontargeted Conditions, 2007–2013 (Odds Ratios)

	Nontargeted Conditions Related to Targeted Conditions (Cardiorespiratory, Cardiovascular)	Other Nontargeted Conditions (Neurology, Surgery)	Difference, Related Conditions—Other Conditions
Difference in slopes between post‐HRRP and pre‐HRRP periods for top performing hospitals	0.981***	0.975***	1.005***
	(0.978, 0.983)	(0.973, 0.978)	(1.002, 1.009)
Difference in slopes between post‐HRRP and pre‐HRRP periods for bottom performing hospitals	0.993***	0.986***	1.007***
	(0.990, 0.996)	(0.983, 0.989)	(1.004, 1.011)
Difference in slope changes, bottom—top	1.013***	1.011***	1.002
	(1.009, 1.017)	(1.008, 1.013)	(0.997, 1.007)
Number of index admissions			23,038,413
Number of hospitals			2,904

Estimates presented in this table are from a logistic regression model that includes patient‐level variables for risk adjustments including comorbidities and hospital‐level control variables. We divide hospitals into groups based on their slope change in the ratio of observed to predicted readmission rates for targeted conditions before and after the HRRP. The top performing hospitals include the top 25 percentile of hospitals in terms of their slope reductions in readmission rates for the targeted conditions before and after the HRRP. The bottom performing hospitals are the bottom 25 percentile. *p < 0.1, **p < 0.05, ***p < 0.01.
