5. Objectives of the bibliometric analysis
To establish an INDEPTH web-based searchable database of all publications based on DSS work.
To conduct a preliminary analysis of content, trends, and relevance.
To use the database as a basis to identify case studies of DSS contributions.
To identify areas where we could increase contributions and value of the DSS platform and add value.

6. Approach Compiling the database
For now, only peer-reviewed, English and French DSS-based publications
Sourced from:
INDEPTH website and contact with sites
PubMed and ISI Web of Science searches using site, country, and key author names
Site reference lists returned to each site for vetting
Analyzing the database
Keyword list customized for DSS relevance
Database contents searched, categorized, and mapped on custom keywords and content

7. Mapping the INDEPTH publication galaxy

21. Summing up some preliminary conclusions
Improving concordance with population health needs
For BOD; less so for Risk Factors)
 but still need more focus on neonatal, NCDs and health transition.
Work is highly relevant to the MDG agenda
concordance with burden is still ok
but TB needs greater attention
Strong tradition in efficacy trials has now shifted to effectiveness studies
Still weak on health systems and policy performance / influence
Publication productivity needs to increase beyond 2.5 papers per year per site
 a problem of analytical capacity in sites
 Need better use of young scientists

22. Way forward for the bibliometrics project
Need your input on conclusions from the preliminary descriptive analyses
Need your suggestions for DSS case studies to showcase.
Need your ideas concerning next steps for using such analyses for advocacy for your collective work
