心房細動を有する脆弱な患者に対するピアメンター支援 (EMPOWER-AF)

2026年11月2日 更新者:Cecilie Mia Lykke Mielow、University College Copenhagen

心房細動を有する脆弱な患者の精神的ウェルビーイングの探求と向上 - ピアメンター介入の無作為化比較試験

The goal of this randomized clinical trial is to evaluate whether a peer-mentor intervention can improve mental well-being among vulnerable patients with atrial fibrillation (AF). Patients with AF often experience anxiety, uncertainty, and reduced quality of life. These challenges are particularly pronounced among individuals with low socioeconomic position, who may face additional barriers to accessing supportive care.

The main question the study aims to answer is:

Does a 16-week peer-mentor intervention reduce anxiety symptoms among patients with AF compared with usual care?

Researchers will compare peer-mentor support plus usual care with usual care alone.

Participants will:

Complete questionnaires about anxiety, depressive symptoms, quality of life, and self-efficacy at baseline and after 16 weeks.

Be randomized either to receive peer-mentor support for 16 weeks or to receive usual care only.

If allocated to the intervention group, be matched with a trained peer mentor with lived experience of atrial fibrillation who provides emotional support and practical guidance through approximately eight contacts over the 16-week period.

The study will also include follow-up using national health registers and a mixed-methods process evaluation exploring participants' and mentors' experiences with the intervention.

詳細な説明

Atrial fibrillation (AF) is the most common sustained cardiac arrhythmia and is associated with significant symptom burden, reduced quality of life, and high levels of psychological distress. Anxiety is particularly prevalent among patients with AF and may worsen symptom perception, increase health-related worry, and negatively affect engagement in self-management and healthcare. Individuals with low socioeconomic position often experience greater disease burden and face additional barriers to accessing supportive care, contributing to social inequalities in cardiovascular health.

Peer support interventions have shown promising effects in other cardiac populations by providing emotional support, normalization of illness experiences, and practical guidance based on lived experience. Such interventions may enhance patients' confidence in managing their condition and navigating everyday life with chronic illness.

The EMPOWER-AF study aims to evaluate the effectiveness of a peer-mentor intervention designed to support vulnerable patients with AF. The intervention is grounded in social cognitive theory, particularly the concept of self-efficacy, and is intended to strengthen patients' ability to manage symptoms, cope with uncertainty, and improve mental well-being.

The study is conducted as a randomized controlled trial with two parallel groups. Participants are randomized to either a peer-mentor intervention in addition to usual care or usual care alone. The intervention lasts 16 weeks and involves one-to-one support between a trained peer mentor and a patient with AF. Peer mentors are individuals with lived experience of AF who have achieved stable everyday management of the condition and who are trained to provide emotional support and experiential guidance. Contacts between mentors and mentees may take place via telephone, face-to-face meetings, or digital communication depending on participant preferences.

In addition to the randomized trial, the study includes an embedded mixed-methods process evaluation to explore participants' and mentors' experiences, mechanisms of impact, and contextual factors influencing engagement with the intervention.

The study seeks to generate evidence on whether peer-based support can improve mental well-being among vulnerable patients with AF and contribute to more equitable and person-centered care for this patient group.

実験的:Peer-Mentor Support + Usual Care

Participants randomized to this arm receive a 16-week peer-mentor intervention in addition to usual care. Each participant is matched with a trained peer mentor with lived experience of atrial fibrillation who provides emotional support, normalization of illness experiences, and practical guidance. The intervention includes approximately eight contacts over 16 weeks delivered via telephone, face-to-face meetings, or digital communication depending on participant preferences. Participants continue to receive usual medical care throughout the study period.

A 16-week peer-mentor program designed to support patients living with atrial fibrillation. Participants are matched with trained peer mentors who have lived experience with atrial fibrillation. Mentors provide emotional support, normalization of illness experiences, and practical non-clinical guidance for managing everyday life with the condition. Contacts between mentors and participants are planned approximately eight times during the intervention period and may take place via telephone, face-to-face meetings, or digital communication according to participant preferences. Mentors do not provide medical advice.

介入なし:Usual care

Participants randomized to this arm receive usual care according to local clinical practice for atrial fibrillation. No peer-mentor support is provided.

主要な結果の測定

結果測定
メジャーの説明
時間枠
Anxiety symptoms measured by the Hospital Anxiety and Depression Scale (HADS-A)
時間枠:Baseline and 16 weeks

Anxiety symptoms are assessed using the Hospital Anxiety and Depression Scale - Anxiety subscale (HADS-A). The subscale consists of 7 items assessing symptoms such as tension, worry, and panic, each scored from 0 to 3. The total score ranges from 0 to 21, with higher scores indicating greater levels of anxiety symptoms.
