Distraction-based interventions for children in the emergency care setting: A realist synthesis based on primary research.

Abstract

Background: The literature underscores the prevalence of pain as the most common presenting symptom in the Emergency Care Setting (ECS) and is associated with anxiety and stress for children. On top of that painful procedures are often required as part of their treatment, making procedural pain a common experience. The substantial evidence supporting the effectiveness of distraction-based interventions (DBI) in relieving pain and anxiety and reducing stress underscores the urgency of addressing this issue. However, the fragmented adoption of standardised DBI highlights the need for further research and implementation.

Purpose: To conduct a realist synthesis based on primary research exploring "what works for whom under what circumstances, how and why?" when implementing DBI in the ECS.

Review methods: Empirical research evidence was retrieved systematically from eight databases covering health and social sciences. The studies were synthesised based on the principles of realist science, drawing on Pawson and Tilley's (1997) and Dalkin et al.'s (2015) programme theory development, which explains the contexts and mechanisms that generate positive outcomes about DBI for children in the ECS.

Results: Of the 2099 studies screened, 64 were included. Screening was conducted 2023 to December 2024. A synthesis of the findings generated five Programme Theories (PT). PT1 focuses on the personalisation of DBI for children in the ECS, PT2 explains the importance of parental participation, PT3 highlights the importance of healthcare workers (HCWs) commitment to adopting DBI in practice, PT4 draws attention to policy-level efforts necessary for implementation support, and PT5 focuses on engaging all stakeholders in the implementation process.

Conclusion: To the authors' knowledge, this is the first study to apply a realist lens to understand the use of DBI in children attending the ECS and present the mechanisms that enable and/or inhibit its implementation and utilisation in everyday clinical practice.

Implications to practice: This realist synthesis provides methodological guidance in the form of PT that can be utilised by clinical practitioners to adopt and implement DBI within the healthcare setting.
