Abbreviations: Ave., average; ICU, intensive care unit; IQR, interquartile range; NHSN, National Healthcare Safety Network; SAAR, Standardized Antimicrobial Administration Ratio.
Undergraduate teaching: facility has a program for medical/nursing students only. Graduate teaching: facility has a program for postgraduate medical training (ie, residency and/or fellowships). Major teaching: facility has a program for medical students and postgraduate medical training.
Calculated as number of ICU beds divided by total number of beds, multiplied by 100.
Calculated as annual patient days divided by annual admissions.
Number and percentage of hospitals contributing antimicrobial use data for each patient-care location type. For example, 125 hospitals among the 449 represented in the adult referent group, or 27.8%, reported data from a medical ICU for ≥9 months in 2017
