Pharmacist workload
To estimate the pharmacist effort required to manage alerts and notifications, we will calculate the total number of referrals to the anticoagulation clinic during the study period. This will be estimated as the number of referrals/alerts per 1000 DOAC prescriptions. We will then also use tools built within the EHR to measure the time (in minutes) from which a pharmacist views a new alert/notification until one of three actions occur: (1) change in medication prescription is made, (2) alert is dismissed (and reason documented), or (3) message is sent to prescribing clinician. Together, this will allow us to estimate the total pharmacist effort required to manage DOAC alerts/notifications through this system (calculated as full-time equivalents [FTE]) required for a given population size of DOAC-treated patients. To further validate these estimates, DOAC pharmacists will also be asked to document their time spent interacting with and acting upon alerts and notifications during two separate two-week periods using a time-tracking worksheet developed for this study.
