Utilization and Clinical Outcomes Across Quintiles of Hospital Average Episode Spending

	Hospital Quintile
	1	2	3	4	5	p for Q1-Q5 difference
Total Episode Spending	$12,220	$13,350	$13,914	$14,505	$16,887	<.001
Readmissions Rate	7%	10%	12%	14%	17%	<.001
ED Revisit Rate	20%	20%	21%	23%	24%	<.001
PAC Utilization Rate	5%	11%	10%	12%	17%	<.001
Complication Rate	6%	10%	11%	12%	14%	<.001

NOTES: Quintiles are based on hospital average episode spending, adjusted for case mix, inflation, year, procedure choice, and hospital characteristics. All outcomes (readmissions, ED revisits, PAC utilization, and complications) are measured within 90 days of surgery and averaged at the hospital level. Complications reflect those documented in the inpatient setting within 90 days of surgery. ED = emergency department; PAC = post-acute care
