title: Improving quality of data extractions for the computation of patient-days and admissions.
abstract: We describe how admissions/discharges/transfers datasets were carefully reviewed for the computation of patient days and admissions used to monitor resistance and antimicrobial use in 9 intensive care units. A visual inspection of datasets and comparisons with other data sources improved accuracy, completeness, and consistency of computations.
