Perineal warm compresses in the second stage of labour have been demonstrated by clinical guidelines as an effective intervention for improving perineal outcomes and mothers’ psychological well-being, yet their adoption in clinical practice remains suboptimal. Therefore, this study aims to bridge the evidence-practice gap through the application of implementation science models and frameworks to facilitate clinical adoption. The investigation will systematically explore the barriers and facilitators to the application of perineal warm compresses in the second stage of labour and subsequently develop a corresponding implementation strategy addressing identified barriers.

This study was guided by the PEDALs model. Using a scoping review and a parallel mixed-methods study to systematically investigate the barriers and facilitators to the application of perineal warm compresses in the second stage of labour. The identified barriers and facilitators were mapped to the domains of the Consolidated Framework for Implementation Research (CFIR). Then we will use a modified nominal group technique to determine seven priority barriers that need to be addressed. These barriers will be input into the CFIR-ERIC implementation strategy matching tool to obtain expert-recommended implementation strategies. Finally, the Delphi method will be employed to select and refine the implementation strategies into a clear and actionable implementation strategy bundle.

This study has been approved by the Ethics Committee of Hebei Medical University, with approval number 2024043. Written informed consent will be obtained from all participants. Study findings will be disseminated through articles in scientific, peer-reviewed journals, and at national and international conferences. This study will begin in August 2025 and be completed in June 2026.
