Improving quality of data extractions for the computation of patient-days and admissions

Published:December 16, 2014DOI:


      • Problems in data extractions can compromise the quality of surveillance denominators.
      • Good communication with all stakeholders is essential during the entire process.
      • A valid list of admissions can facilitate information extraction from other databases.
      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.
