Background: Apixaban (ELIQUIS®) is a direct oral anticoagulant authorised for multiple indications in the European Economic Area (EEA). Additional risk minimisation measures (aRMMs) to address the risk of bleeding include educational materials comprising a Prescriber Guide and Patient Alert Card.
Objectives: This study evaluated effectiveness of the apixaban Prescriber Guide and Patient Alert Card in terms of healthcare professional (HCP) and patient knowledge of associated bleeding risk, as well as material distribution, utilisation and behaviour.
Methods: This non-interventional, cross-sectional study included online surveys in ten countries that represented a high proportion of apixaban usage in the EEA. The HCP source population was based on HCP lists used for communications about and distribution of the risk minimisation materials. Patient recruitment took place via HCPs. Study participants included HCPs involved in apixaban treatment and patients treated with apixaban (or their caregivers) for multiple indications. Data collection took place over an 18-month period between August 2015 and February 2017.
Results: Survey responses from 385 HCPs and 125 patients/caregivers were analysed. HCP knowledge of bleeding risk included early recognition of symptoms requiring immediate contact with an HCP (96.1%), appropriate dosing (83.6%), contraindications (76.1%) and subpopulations at increased risk of bleeding complications (ranging from 63.5 to 85.9%). Patient knowledge included abnormal bleeding as an important side effect (71.2%), communicating risk factors to HCPs (76.8%) and recognition of potential bleeding symptoms ('high' knowledge levels 22.4%, 'moderate' knowledge levels 49.6%). Of 226 (58.7%) HCPs who recalled receiving/obtaining the Prescriber Guide, 97.8% read at least part of it and 74.8% had used it to assist patient discussions. Of 74 (59.2%) patients who were aware of the Patient Alert Card, 89.2% recalled receiving/obtaining a copy. When received, 90.9% of patients read the card at least once and 93.9% kept it with them at least some of the time.
Conclusions: HCP and patient respondent knowledge of bleeding risk was satisfactory. Although not optimal, reach of the aRMMs was consistent with other studies. No modifications to aRMM content were required. To increase reach, the Prescriber Guide has been provided in an additional format as a web-based platform whilst the Patient Alert Card was included within product packaging.
