yes / Direct oral anticoagulants (DOACs) uptake for stroke prevention in atrial fibrillation has been slow.[1] This study aimed to profile the prescribing of DOACs over three years to identify factors associated with DOAC prescribing in a Clinical Commissioning Group (CCG) without restrictions to DOACs use. The objectives were to identify: - Characteristics of patients prescribed oral anticoagulant (OAC) in a sample of general practices; - Who initiated the prescribing of OAC; - Recorded reasons for prescribing a DOAC rather than warfarin;

yes / Warfarin and direct oral anticoagulants (DOACs) have been shown to reduce the risk of stroke in patients with atrial fibrillation, yet many patients are still not being anticoagulated. This article discusses the barriers to the initiation of oral anticoagulants, in particular DOACs, and how these can be overcome.

Yes / Background and Objective In England, the uptake of direct oral anticoagulants (DOACs) for stroke prevention in atrial fbrillation has been slow and varied across diferent Clinical Commissioning Groups (CCGs). This study aimed to profle the prescribing of oral anticoagulants for stroke prevention in patients with atrial fbrillation over 3 years in a CCG without restrictions to DOACs use to understand more about organisational and/or individual barriers to the early uptake of DOACs. Methods Data were collected from nine general practices between 1 April 2012 and 31 March 2015 of patients who were initiated on the oral anticoagulant therapy. Data were analysed descriptively and with independent Student’s t test and Chi square test to explore if there was an association between type of oral anticoagulant initiated and sex, age, type of prescriber and prior aspirin use. Results The early uptake of DOACs signifcantly increased over the study period (p<0.0001; medium size efect φc=0.372). There was no statistically signifcant diference between sex or age and type of oral anticoagulant initiated. Primary-care prescribers were responsible for initiating the majority of oral anticoagulants (71%; N=257) and driving the use of DOACs (72%, N=71). Patients switched from aspirin to an oral anticoagulant were more likely to be initiated on warfarin than a DOAC. Conclusions The early use of DOACs, in a CCG without restrictions to their use, was embraced by primary-care prescribers in this particular CCG. / Bayer Pharmaceuticals via an unrestricted educational grant.

Yes / Objective: To better understand the factors influencing the uptake of direct oral anticoagulants (DOACs) across different health economies in National Health Service England from the perspective of health professionals and other health economy stakeholders. Design: Qualitative interview study using a critical realism perspective and informed by the Diffusion of Innovations in Service Organisations model. Setting: Three health economies in the North of England, United Kingdom. Participants: Healthcare professionals involved in the management of patients requiring oral anticoagulants, stakeholders involved in the implementation of DOACs and representatives of pharmaceutical industry companies and patient support groups. Intervention: Semistructured interviews (face-to-face or telephone) were conducted with 46 participants. Interviews were analysed using the Framework method. Results: Identified factors having an impact on the uptake of DOACs were grouped into four themes: perceived value of the innovation, clinician practice environment, local health economy readiness for change, and the external health service context. Together, these factors influenced what therapy options were offered and prescribed to patients with atrial fibrillation. The interviews also highlighted strategies used to improve or restrict the uptake of DOACs and tensions between providing patient-centred care and managing financial implications for commissioners. Conclusions: The findings contribute to the wider literature by providing a new and in-depth understanding on the uptake of DOACs. The findings may be applicable to other new medicines used in chronic health conditions. / This work presents research funded by the Pharmacy Research UK (grant number: PRUK-2018-GA-1-KM) and Leeds Teaching Hospitals NHS Trust (grant number: N/A).
