Abstract Background Atrial fibrillation (AF) often influences daily life with symptoms like palpitations, dyspnoea, fatigue, fear and anxiety. Research show that patients with AF benefit from prevention and rehabilitation interventions. However, evidence is scarce and mainly hospital-based, and it is unknown whether the transition to the primary healthcare sector gives the same positive results. In 2019, a Danish primary care Health Center and the cardiology department at the local hospital completed a multidimensional prevention and rehabilitation intervention for patients with AF. Purpose To investigate the feasibility of delivering a multidimensional prevention and rehabilitation intervention for patients with AF in a primary care Health Center. Methods This study was a mixed-methods, non-randomized, intervention, feasibility study. A convergent mixed-methods design was used, and results were illustrated in side-by-side joint displays. Patients were included at a Hospital AF clinic referring to the Health Center. The prevention and rehabilitation intervention consisted of risk factor management, patient education, physical activity and yoga. Two patient-reported outcomes measures (PROMs) were used, the HeartQoL measuring health-related quality of life (HRQoL) and the Hospital Anxiety and Depression Scale (HADS) measuring symptoms of anxiety and depression. Data were collected at baseline (T0), at end of intervention (T1), and at two-months follow-up (T2) and analysed descriptively. Focus group interviews were analysed thematically and covered experiences of participating, needs and preferences, outcomes and feasibility of collecting PROMs. The reporting was guided by the Consolidated Standards of Reporting Trials (CONSORT) extension to pilot and feasibility trials. Results 43 patients (53% women; median age 66 (range 52-81) years) completed the intervention. Table 1 shows that HRQoL increased, and symptoms of anxiety and depression decreased. These results maintained at follow-up. Figure 1 shows the qualitative themes. Patients experienced being understood and supported by health professionals and peers. They thought it difficult to know what their needs were. However, some patients had specific preferences for interventions. For changes in outcomes, the patients identified that gaining tools and knowledge about the disease from the interventions helped. It was feasible to collect PROMs during the intervention and finally, the patients had an attention to what comes next, when finishing the intervention in the primary care setting. Conclusion It was feasible to deliver a multidimensional prevention and rehabilitation intervention for patients with AF at a primary care Health Center. HRQoL increased and symptoms of anxiety and depression decreased. The patients experienced being supported and gaining tools and knowledge to handle AF. Future large randomized controlled trials must confirm these results.
