Allowing the discharge medication list to pull data from EMAR

We have an issue with the current process of last dose and next dose due. We need a way that the last dose due pulls from the EMAR and not have to manually entered in prescription entry. Our providers complete the Discharge Med rec and they do not have the dates/times available to enter the correct fields. This should be an automatic pull from the last dose in the EMAR to prevent user error and issues with manually typing data
