Prescriptions/patients
EMERGENCY
Our system for assessing DOAC prescription appropriateness will include DOAC prescriptions written in an ambulatory setting for all adult (age ≥ 18) patients who see an eligible prescriber. This includes patients that were initially prescribed a DOAC before the trial commencement but develop unsafe use during the study period. Prescriptions will be excluded if they were written in the Emergency Department or hospital setting (including upon discharge) or in a skilled nursing facility or another institutionalized setting, as prescribers in these settings typically do not follow patients longitudinally and therefore would not be appropriate targets for notifications when prescribing issues develop after the initial prescription is written. Further, inpatient DOAC prescriptions already undergo pharmacy review.
