OBJECTIVE: To assess the capacity for research collaboration and implementation research in strengthening networks and institutions in developing countries. METHODS: Bibliometric analysis of implementation research on diseases of poverty in developing countries from 2005 to 2010 through systematically searching bibliographic databases. Methods identified publication trends, participating institutions and countries and the cohesion and centrality of networks across diverse thematic clusters. RESULTS: Implementation research in this field showed a steadily growing trend of networking, although networks are loose and a few institutions show a high degree of centrality. The thematic clusters with greatest cohesion were for tuberculosis and malaria. CONCLUSIONS: The capacity to produce implementation research on diseases of poverty is still low, with the prominence of institutions from developed countries. Wide ranges of collaboration and capacity strengthening strategies have been identified which should be put into effect through increased investments.

The A(H1N1) influenza pandemic has been a challenge for public health surveillance systems in all countries. An objective evaluation has not been conducted, as yet, of the performance of those systems during the pandemic. This paper presents an algorithm based on Benford's Law and the mortality ratio in order to evaluate the quality of the data and the sensitivity of surveillance systems. It analyses records of confirmed cases reported to the Pan American Health Organization by its 35 member countries between epidemiological weeks 13 and 47 in 2009. Seventeen countries did not fulfil Benford's Law, and mortality exceeded the regional average in 40% of the countries. The results suggest uneven performance by surveillance systems in the different countries, with the most frequent problem being low diagnostic coverage. Benford's Law proved to be a useful tool for the evaluation of a public health surveillance system's performance.
