↵* Compare against n in top row.
↵† Each criterion is added sequentially. Compare against n of the immediately preceding criterion.
^‡The second iteration began with the removal of Appointment Procedures. Therefore, values in this row serve as the baseline for the second iteration.
^§The FIT Daily Report timed out due to restrictions in place from Epic Reporting Workbench and did not yield results. In this institution’s Epic system, reports must include at least the Providers or Encounter Department field or have a patient base selected to prevent timing out.
^‖These criteria are revised from the previous iteration.
