Domestic Violence Fatality Reviews/Domestic Homicide Reviews (DVFRs/DHRs) are multi-agency reviews aimed at reducing domestic homicides. This study systematically reviews research that examines DVFR/DHR recommendations, impact of these recommendations and proposals for improving DVFR/DHR processes. A narrative synthesis was adopted due to the diversity of the 11 studies reviewed. Themes identified from recommendations included: training and awareness; service provision and coordination; and recommendations for children. Regarding DVFR/DHR processes, standardization, diverse teams, and additional resources were highlighted. There was little evidence of whether DVFR/DHR recommendations were implemented. Findings can strengthen DVFR/DHR operationalization and impacts.
