Effect of evidence-based pharmacy care on satisfaction and cognition in patients with non-valvular atrial fibrillation taking rivaroxaban

Abstract

Purpose: We aimed to determine the effects of using evidence-based pharmacy care on satisfaction and cognition among patients with non-valvular atrial fibrillation (NVAF) and taking rivaroxaban. Patients and Methods: Between July 2018 and June 2019, 200 consecutive hospitalized patients taking oral rivaroxaban, who were diagnosed with NVAF and registered in the hospital information management system, were randomly assigned to a control group (n=100) and a study group (n=100) in a single-blind manner. The control group received pharmaceutical care based on the general pharmaceutical care model whereas the study group received care based on an evidence-based pharmaceutical care model. Patients’ satisfaction and cognition were evaluated regularly using questionnaires. The follow-up time was 1 year. We compared differences in satisfaction and cognition between the two groups after pharmaceutical-related care administered by clinical pharmacists. Results: The study group had higher satisfaction scores than the control group after the EBP intervention (14.58±0.88 vs.13.81±1.01, p<0.01); cognition scores were also higher in the study group (22.58±2.19 vs 20.80±3.02, p<0.01) after the intervention. In the study group, satisfaction was increased from a score of 10.15±1.33 before the EBP intervention. Cognition also increased after the intervention in the study group, from a score of 9.88±4.09 pre-intervention. In the control group, satisfaction was 10.04±1.29 before the traditional pharmaceutical care intervention, smaller than the 13.81±1.01 after the intervention (p<0.01). Cognition in the control group was 9.83±3.51 before traditional pharmaceutical care, smaller than the 20.80±3.02 after the intervention (p<0.01). Conclusion: The care model based on evidence-based pharmacy care can improve patient satisfaction and cognition, providing more comprehensive safety and efficacy of subsequent medication.
