Understanding for whom, under what conditions, and how an integrated approach to atrial fibrillation service delivery works: a realist review.

To understand for whom, under what conditions, and how an integrated approach to atrial fibrillation (AF) service delivery works (or does not work). A realist review of integrated approaches to AF service delivery for adult populations aged ≥18 years. An expert panel developed an initial programme theory, searched and screened literature from four databases until October 2022, extracted and synthesized data using realist techniques to create context-mechanism-outcome configurations for integrated approaches to AF service, and developed an integrated approach refined programme theory. A total of 5433 documents were screened and 39 included. The refined programme theory included five context-mechanism-outcome configurations for how clinical and system-wide outcomes are affected by the way integrated approaches to AF service delivery are designed and delivered. This review identifies core mechanisms underpinning the already known fundamental components of integrated care. This includes having a central coordinator responsible for service organization to provide continuity of care across primary and secondary care ensuring services are patient centred. Additionally, a fifth pillar, lifestyle and risk factor reduction, should be recognized within an AF care pathway. It is evident from our provisional theory that numerous factors need to interlink and interact over time to generate a successfully integrated model of care in AF. Stakeholders should embrace this complexity and acknowledge that the learnings from this review are integral to shaping future service delivery in the face of an aging population and increased prevalence of AF.
