Introduction: Perinatal mortality encompasses stillbirths and early neonatal deaths. A perinatal death surveillance and response cycle has been recommended by the World Health Organization for use in the review of perinatal deaths. The main components of the cycle include identifying and reporting perinatal deaths, and reviewing the deaths, including potentially modifiable factors, in order to measure and improve quality of care provided to women and infants. There is no consensus on the best way to design, implement and conduct perinatal death reviews. This systematic review aims to identify standardised tools that are used to review perinatal deaths. Objectives: The primary aim of this protocol is to describe methodology for a systematic search of the literature to identify standardised tools that are used to review perinatal deaths in upper-middle to high-income countries. Review tools may include standardised checklists, forms, frameworks or other structured documents used to review perinatal deaths. Review tools will be appraised to see if they incorporate the identification of modifiable factors in perinatal deaths and establish recommendations for improvements to quality of care provided. Methods: A systematic review of the literature will be performed to identify peer-reviewed publications and grey literature describing the use of perinatal mortality review tools without date restrictions. The eligibility of review tools for inclusion will be based on inclusion and exclusion criteria applied to the SPIDER framework. Data will be extracted based on the structure and content of included review tools, and the tools will be appraised using the Appraisal of Guidelines Research and Evaluation Health Systems (AGREE-HS) instrument. Conclusion: This systematic review protocol for identifying and appraising standardised perinatal mortality review tools may help to establish the optimal way to structure a standardised review process for perinatal mortality in middle- to high-income countries.
