Priority gaps and promising areas in maternal health research in low- and middle-income countries: summary findings of a mapping of 2292 publications between 2000 and 2012.
This commentary sums the findings of a series of papers on a study that mapped the global research agenda for maternal health. The mapping reviewed published interventional research across low- and middle-income countries (LMICs) from 2000 to 2012, specifically focusing on investigating the topics covered by this research, the methodologies applied, the funding landscape and trends in authorship attribution.The overarching aim underpinning the mapping activities was to evaluate whether research and funding align with causes of maternal mortality, and thereby highlight gaps in research priorities and governance. Fifteen reviewers from 8 countries screened 35,078 titles and abstracts, and extracted data from 2292 full-text articles.Over the period reviewed, the volume of publications rose several-fold, especially from 2004 to 2007. The methodologies broadened, increasingly encompassing qualitative research and systematic review. Malaria and HIV research dominated over other topics, while sexually-transmitted infection research progressively diminished. Health systems and health promotion research increased rapidly, but were less frequently evaluated in trials or published in high-impact journals. Relative to disease burden, hypertension had double the publications of haemorrhage. Many Latin American countries, China and Russia had relatively few papers per billion US dollars Gross Domestic Product. Total LMIC lead authorships rose substantially, but only a quarter of countries had a local first author lead on >75% of their research, with levels lowest in sub-Saharan Africa. The median Impact Factor of high-income country led papers was 3.1 and LMIC-led 1.8. The NIH, USAID and Gates Foundation constituted 40% of funder acknowledgements, and addressed similar topics and countries.The commentary notes that increases in outputs and broadening of methodologies suggest research capacity has expanded considerably, allowing for more nuanced, systems-based and context-specific studies. However, funders seemingly duplicate efforts, with topics and countries either receiving excessive or little attention. Better coordinated funding might reduce duplication and allow researchers to develop highly-specialised expertise. Repeated scrutiny of research agendas and funding may foment shifts in priorities. Building leadership capacity in LMICs and reconsidering authorship guidelines is needed.
