Acknowledgements
We express gratitude to all the care providers who shared their experiences as well as all the participants recruited in the Room4Birth RCT. We would also like to thank study midwife Anna Andrén for contributing to the development of the interview guide and for conducting most of the interviews. The implementation process would not have been possible without the dedicated work by the study midwife Lisa B Skogström, study assistant nurse Åsa Svanlund, building project representatives, contact midwives, section leaders and study ambassadors at the labour ward.
