CI = confidence interval; OR = odds ratio.

^*n denotes the number of patients who died within 30 days, and N denotes the number of patients with follow-up for mortality. Patients with incomplete follow-up were excluded from the denominator in the calculation of the frequency (n/N, %) for this outcome. Follow-up for mortality was completed for 2062 (99.3%) of all 2076 patients.

^†Unadjusted statistical comparisons of mortality by the processes of care performed were tested using univariate multilevel models.

^‡All ORs in this table were adjusted for PSI risk class and additional baseline patient, provider, and site characteristics shown in Table 1, and calculated using multilevel logistic models.
