Table 2.

Adjusted mortality rates by race/ethnicity: Base model

a. Adjusted mortality rate = # deaths / 100 hospitalizations
Mortality outcome	Whites	Blacks	Hispanics	Asians
Inpatient mortality	5.29	4.28*	5.00*	5.34
30-day mortality	10.10	7.88*	8.82*	8.52*
90-day mortality	15.40	13.10*	13.43*	13.12*
180-day mortality	19.09	16.92*	16.64*	16.27*

b. Odds ratio of adjustment mortality differences from non-Hispanic whites
Mortality outcome	Blacks	Hispanics	Asians
Inpatient mortality	0.75*	0.94*	1.02
30-day mortality	0.70*	0.84*	0.83*
90-day mortality	0.80*	0.83*	0.81*
180-day mortality	0.83*	0.81*	0.79*

Notes:

1) For Table 2a, the adjusted rate of mortalitywere estimated using a linear probability model of mortality with the following covariates besides race/ethnicity: age, sex, Elixhauser comorbidity indicators, and area level indicators of income, uninsurance rate, provider availability, rural/urban location and hospital fixed effects.

2) For Table 2b, the odds ratio (reference=non-Hispanic Whites) were estimated using a random effects (hospital) logistic model of mortality with the same covariates as for Table 2a.

3) In both Tables 2a and 2b, * denotes significant difference compared to non-Hispanic whites with p <0.05
