With Stage 1 in 2014, there is a change to the CPOE denominator. Does my facility have to use the old denominator or the new denominator?

In 2014, there will be an optional alternate measure to the objective for CPOE. The current measure for CPOE is based on the number of unique patients with a medication in their medication list that was entered using CPOE. The new, alternate measure is based on the total number of medication orders created during the EHR reporting period. An EP, EH or CAH may select either measure for this objective in Stage 1 in order to achieve Meaningful Use. (Note that this alternative measure will be required for all providers in Stage 2.) Alternate Measure:
More than 30 percent of medication orders created by the EP or authorized providers of the EH's or CAH's inpatient or emergency department (POS 21 or 23) during the EHR reporting period are recorded using CPOE.
