Building the evidence base for global health policy: the need to strengthen institutional networks, geographical representation and global collaboration

Abstract

National public health institutes and WHO collaborating centres, and their global networks, are a key resource to support public health system strengthening with essential public health functions and generate evidence for health policy central to national health and socioeconomic development. The COVID-19 pandemic has laid bare global inequities in public health capacities, made urgent the need to examine sources of global knowledge and understand how to better invest in and use public health institutes and their capacities. This analysis paper incorporates experiences and perspectives from the WHO and International Association of National Public Health Institutes including the ongoing pandemic and work conducted in the UK-WHO ‘Tackling Deadly Diseases in Africa Programme’. We acknowledge geographical disparities in public health capacities both within and across countries and regions, provide examples of novel ways of working for global health actors, and define the challenging environment in which public health authorities operate. We identify four incentives for all countries to invest in public health and strengthen institutions: (1) transparency and trust; (2) socioeconomic dividends; (3) collective health protection and (4) knowledge sharing and equity. By pursuing shared priorities; enabling voices from low-resource settings to be more equitably heard; facilitating collaboration and learning within and across regions, we articulate actionable next steps to develop and better harness public health institutes and international networks.
