The challenge of managing multimorbid atrial fibrillation: a pan-European European Heart Rhythm Association (EHRA) member survey of current management practices and clinical priorities

As part of the EHRS-PATHS study examining comorbidities in atrial fibrillation (AF) across Europe, the aim was (i) to evaluate how multimorbidity is currently addressed by clinicians during AF treatment to characterize the treatment structure and (ii) to assess how the interdisciplinary management of multimorbid AF is currently conducted. An online survey was distributed among European Heart Rhythm Association (EHRA) members in Europe that included 21 questions and a free-text option for comments on detection, assessment, and management of AF-related comorbidities. A total of 451 responses were received with 339 responses eligible for inclusion. Of these, 221 were male (66%), 300 (91.5%) were physicians, and 196 (57.8%) were working in academic university teaching hospitals. Half of the respondents managed between 20 and 50 patients per month with multimorbid AF. Varying rates of specialist services and referral to these services were available at each location (e.g. heart failure and diabetes), with a greater number of specialist services available at academic university teaching hospitals compared with non-teaching hospitals [e.g. anticoagulation clinic 92 (47%) vs. 50 (35%), P < 0.03]. Barriers to referring to specialist services for AF comorbidities included lack of integrated care model (n = 174, 51%), organizational or institutional issues (n = 145, 43%), and issues with patient adherence (n = 126, 37%), highlighting the need for organizational restructuring and developing an integrated collaborative evidenced-based approach to multimorbid AF care. The survey and analyses of free-text comments demonstrated the need for systematic, integrated management of AF-related comorbidities, and these results will inform the next phases of the EHRA-PATHS study.
