Performance of Individual Processes of Care for Selected Patient Subgroups

Patient Subgroups	Oxygenation Assessment (%)	Blood Cultures Before Antibiotic Administration (%)	Antibiotic Administration within 4 Hours (%)	Appropriate Antibiotic Therapy (%)
All inpatients (N = 2076)	97.6	63.3	78.6	63.0
Processes of care performed (No.)*
0–2 (N = 534)	93.4	25.5	43.8	15.2

Age (y)

ICU or CCU admission

Day of admission (N = 141)	98.6	70.2†	85.8†	40.4‡

Study intervention group§
Low-intensity (N = 566)	96.3	53.5‡	77.0	50.0‡
Moderate-intensity (N = 661)	99.1	57.6‡	79.7	59.6‡
High-intensity (N = 849)	97.4	74.2‡	78.8	74.3‡

ICU = intensive care unit; CCU = coronary care unit.

^*Patients who had all 4 processes of care performed by definition had 100% of all processes of care performed. We did not perform statistical comparisons for these patient subgroups because the individual processes of care and the cumulative number performed are interdependent.

^†P <.05 based on a 2-sided chi-square test.

^‡P <.001 based on a 2-sided chi-square test.

^§Comparisons of study intervention group use the Rao and Scott second-order corrected Pearson chi-square statistic to account for the clustering of patients within providers and sites and test for an ordinal association between study intervention group and the performance of each process of care.
