BACKGROUND: Maternal death generates a great impact on public health, and it is recognized that its main cause is postpartum hemorrhage (PPH). Therefore, the objective was to analyze the bibliometric profile of the world scientific production on maternal mortality due to PPH. MATERIALS AND METHODS: Bibliometric study that included original articles indexed in Scopus, identified by means of a search strategy that included MESH terms and logical operators. Bibliometric indicators were estimated with the SciVal tool, and the VOSwiever program was used for co-occurrence networks by key terms and co-authorship by country. RESULTS: There has been an increase in the number of publications in the past 5 years. Regarding co-occurrence, the most frequent terms were "postpartum hemorrhage" and "maternal mortality." The United States and the United Kingdom are positioned as those with the highest density of publications; in addition, Australia evidences collaboration with Canada and South Korea. Publications with national collaboration were more frequent (36%). BMC Pregnancy and Childbirth is the most productive journal, although BJOG: An International Journal of Obstetrics and Gynecology has a higher normalized impact. The authors with the highest scientific output belong to an institution in the Netherlands. Vrije Universiteit Amsterdam and Leiden University are the most productive. CONCLUSION: Scientific activity on maternal mortality due to PPH is increasing and its main means of dissemination are high-impact journals. National collaboration was more frequent, with the active participation of authors and institutions from the Netherlands and the United States. [ABSTRACT FROM AUTHOR]
