Scale Up and Spread

GHLI develops and evaluates models of dissemination, diffusion and scale up. Through this work we have pioneered the AIDED model, a practical framework for understanding what works in scaling up evidence-based health interventions in low-income countries. This model proposes five interrelated components that are essential to the complex process of scale up: assessing the landscape, innovating to fit the environment, developing support, engaging key stakeholders and devolving efforts for spreading the innovation.

Covid Protect Roadmap

With the outbreak of the COVID-19 pandemic in 2020, GHLI recognized the unique opportunity available to study the scale up and spread of innovations developed to respond to the crisis. Specifically, we aimed to understand how some geographies are able to make extraordinary progress in using digital health innovations to improve the health of the population, particularly in times of crisis. We sought to identify approaches and tools that may serve as practical resources for clinicians, practitioners in social care, digital technology leads, executives and others. In collaboration with the Norfolk and Waveney Clinical Commissioning Group (Norwich, UK), the Eastern AHSN (Academic Health Science Network, Cambridge, UK), and Relentless Leadership, Ltd., we used a rapid case study approach to distill learnings from Norfolk and Waveney's implementation of Covid Protect, a local digital approach to support individuals most clinically vulnerable to severe illness from the COVID-19 virus. The result was a Roadmap, which highlights key processes, practices and tools related to the design and implementation of the project. Click here to read the publication.
