Background: Inappropriate DAOC dosing is precuarious and frequently encountered. Apixaban is the most reported DOAC to be inappropriately dosed. We examined the effect of adding a Clinical Pharmacist to the cardiology team rounds to the standard practice in Apixaban prescription patterns in a tertiary center in KSA.
Objective: To determine the effect of clinical pharmacy services on Apixaban dose appropriateness upon discharge in Atrial Fibrillation patient pobulation.
Methods: This is a single-center, retrospective cohort of patients with atrial fibrillation using a quasi-experiment of pre-post design to evaluate Apixaban dose appropriateness using clinical pharmacy services. Clinical pharmacist was added to the team to evaluate and change the regimen according to FDA dosing. Data were collected for 9 months for each, patients were followed up for efficacy and safety outcomes for 1 year.
Results: A total of 550 patients were initially collected after follow-up, the number of patients was in the pre-phase cohort (NO CCP; n= 112) from July 2018 to the March 2019 and compared to post phase cohort (CCP, n=103) from July 2019 to March 2020. 215 Patients were included, For primary end point, CCP cohort had significantly appropriate prescriptions of apixaban compared to Non-CCP (90.2 % vs 71.5 %, p<0.001)., no differences in thromboembolic and hemorrhagic adverse events betewwn 2 cohorts.
Conclusion: A multidisciplinary team approach including clinical pharmacy services is effective in increasing the appropriate use of Apixaban upom discharge without apparent increased risk of bleeding or Adverse events.
