IntroductionThe psychological outcomes for many parents who experience perinatal loss depend on nursing staff’s ability to provide effective bereavement support. However, most nurses and midwives lack the ability to provide bereavement care and suffer from heavy emotional burden. The study aims to investigate the effectiveness of the perinatal bereavement care training programme on nurses and midwives to increase their perinatal bereavement care confidence (PBCC) and to reduce secondary traumatic stress and emotional exhaustion.Methods and analysisThis study will follow a mixed methodology consisting of two stages. The first stage will adopt a pre/post repeated quasi-experimental design without a control group. The second stage will use a qualitative interview study. This study will be conducted in a tertiary maternity hospital in China in 2022–2023. Ethical approval was obtained from the institutional review board in January of 2020. Outcome measures will be assessed using the Chinese version of the PBCC, STS and the EE subscale of Chinese Burn-out Inventory at baseline, postintervention and at the 3-month follow-up. Participants will be interviewed to understand their perceptions of the training programme.Ethics and disseminationThis research protocol was approved by the Ethics Committee of the Women’s Hospital School of Medicine, Zhejiang University (IRB no. 20210091). The results will be disseminated through peer-reviewed journals and academic conferences.Trial registration numberChiCTR2100049730.
