Anticoagulation Interventions by Pharmacists in Acute Care.

Background: Clinical pharmacy key performance indicators (cpKPIs) relate to activities performed by pharmacists that have been shown to improve patient outcomes. Within Saskatchewan Health Authority (SHA) Regina, most cpKPIs are incorporated into the organization's clinical practice standards, which provide guidance in prioritizing care, especially for high-risk medications, including anticoagulants. To track pharmacists' interventions associated with clinical practice standards, a locally developed electronic data-capture system (known as AIM High) was implemented.

Objectives: To quantify and describe pharmacists' anticoagulation interventions on 16 wards with dedicated ward-based clinical pharmacists and to compare intervention rates between the cardiology and internal medicine wards to further evolve the organization's practice model.

Methods: Data from the electronic data-capture system were retrospectively analyzed for a 5-year period (January 2016 to December 2020).

Results: A total of 94 201 interventions were recorded in the AIM High system (average 362 interventions per week or 26 interventions per pharmacist per week). Of these, 15 661 (16.6%) cited the anticoagulation standard (average 60 anticoagulation interventions per week or 4 anticoagulant interventions per pharmacist per week). For the cardiology and internal medicine wards, 4183 of 11 888 (35.2%) and 9034 of 54 843 (16.5%) interventions cited the anticoagulation standard, respectively. The top 4 types of anticoagulation interventions were dose changed ( = 4372 or 27.9%), drug started or restarted ( = 3867 or 24.7%), patient education ( = 3094 or 19.8%), and drug discontinued ( = 2944 or 18.8%).

Conclusion: Dedicated ward-based clinical pharmacists were following clinical practice standards incorporating the majority of cpKPIs to complete anticoagulation interventions. The types of anticoagulation interventions evolved over time and were influenced by the patient population.
