Abstract
Global health reciprocal innovations originate in low-income and middle-income countries as well as high-income countries before their developers communicate about them with potential adopters in other countries as a transnational team. While communication technology has enabled a more rapid and broader sharing of information about innovations to prevent disease and improve health, innovations of various types have spread among countries, at all levels of income, for many centuries. In this article, we introduce the idea of reciprocal coproduction as a basis for the international sharing of information about innovations that exhibit potential for improving global health. Reciprocal coproduction occurs through two relational team-based processes: developer-led reinvention of an innovation so that it retains its desirable causal effects and implementer-led adaptation of that innovation so that it is compatible with new contexts into which it is introduced. Drawing on research and our own experiences across a range of health issues, we discuss common barriers to reciprocal coproduction and the diffusion of reciprocal innovations. We conclude with lessons drawn from dissemination and implementation science about the effective translation of reciprocal innovations from country to country so that researchers, policy-makers and social entrepreneurs can best ensure equity, accelerate adoptions and heighten the likelihood that global health reciprocal innovations will make a positive difference in health.
