Atrial fibrillation (AF) accounts for up to one third of strokes, one of the lead mortality causes worldwide. The European Society of Cardiology guidelines recommend opportunistic screening as a means to increase the odds of early detection and institution of appropriate treatment according to risk factors identified. However, in most countries there are various barriers to effective uptake of screening, including low awareness. The Atrial Fibrillation Association is a patient association engaged with raising awareness of AF. Establishing a partnership with the International Pharmacists for Anticoagulation Care Taskforce, we set as goals to test a model for raising awareness of AF involving pharmacists globally; and to identify barriers and enablers to its implementation. A cross-sectional study was conducted during the Arrhythmia Alliance World Heart Rhythm Week. Pharmacists from 10 countries invited individuals (≥ 40 years; without anticoagulation therapy of AF) to participate in the awareness campaign. Participants agreeing were engaged in the early detection of AF (EDAF) using pulse palpation. Individuals with rhythm discrepancies were referred and prospectively assessed to have information on the proportion of confirmed diagnosis, leading to estimate the detection rate. Interviews with country coordinators explored barriers and enablers to implementation. The study involved 4193 participants in the awareness campaign and 2762 in the EDAF event (mean age 65.3 ± 13.0), of whom 46.2% individuals were asymptomatic, recruited across 120 sites. Most common CHA2DS2-VASc risk factor was hypertension. Among 161 patients referred to physician, feedback was obtained for 32 cases, of whom 12 new arrhythmia diagnoses were confirmed (5 for AF, 2 for atrial flutter), all among elders (≥ 65 years). Qualitative evaluation suggested a local champion to enable pharmacists’ success; technology enhanced engagement amongst patients and increased pharmacists’ confidence in referring to physicians; interprofessional relationship was crucial in success. This study suggests pharmacists can contribute to greater outreach of awareness campaigns. Effective communication pathways for inter-professional collaboration were suggested enablers to gain full benefits of EDAF.

Conflict of interest
T. Lobban is the Founder and CEO of AF Assoc and Arrhythmia Alliance, a non-profit registered charity aiming to raise awareness of atrial fibrillation (AF), which receives funding from various sources, including donations, fundraising, grants, and trusts. Most of the authors are members of International Pharmacist for Anticoagulation Care Taskforce (FAC, VL, SA, MCC, DG, RV, JP, KML), an organization representing pharmacists with interests in anticoagulation, under the statutes of DRM-Foundation. DRM-Foundation has received funding in the past from Bayer Global and from Pfizer, Canada. S. Antoniou received personal fees and/or non-financial support from Bayer, Boehringer Ingelheim, Daiichi Sankyo and BMS/Pfizer related to AF anticoagulant management. B. Freedman reports grants to the institution, for investigator-initiated studies from Pfizer/BMS, and Bayer and Boehringer Ingelheim personal fees and/or non-financial support from Bayer, Boehringer Ingelheim, and BMS/Pfizer, related to screening for AF. None of these companies had any influence on the study design, conduct or review of results presented; neither did they provide any funding for the development of the study described.
The Project was approved by Egas Moniz Ethical Review Board, Portugal (No. 319), Univerzita Karlova Eticka Komise, Czech Republic (No. 911), Barts Health NHS Trust Ethics Committee (No. 10357), the National Institute of Pharmacy and Nutrition in Hungary (No. 29517) and The Chinese University of Hong Kong Ethics Committee (CRE-2014.012). The remaining countries after consulting with their Local or National Committees, because the law mentions that as long as the activity is within the normal scope of pharmacy practice data may be used for observational studies, it was considered that the precedent decisions were valid. As an example, regulatory law for observation studies in France states that ethical approval by an Ethics Committee is not mandatory when looking at healthcare professional practices (Article R1121-1-II of the Public Health Code, Decree No. 2017-844, 9th May 2017; available at https://www.legifrance.gouv.fr/affichTexte.do?cidTexte=JORFTEXT000034634217&categorieLien=id. In fact, the trend to use anonymous patient data as part of the provided care and support and acknowledge its use is being adopted in many countries by various research organisations following recommendations from patients themselves, quoting “This work uses data provided by patients and collected by the NHS as part of their care and support” available at www.usemydata.org.uk.Data collection was also notified to the competent bodies (e.g. Comissão Nacional de Proteção de Dados, Portugal). Patients agreeing to the EDAF gave their written consent. Only in Spain, France and Hungary were oral consent considered sufficient by the national legislation, as long as the pharmacist clearly provided all information orally, which was ensured.
The informed consent included a section authorising publication of data in a compiled and anonymized format. The investigation conforms with the principles outlined in the Declaration of Helsinki .
