A conceptualisation of scale-up and sustainability of social innovations in global health: a narrative review and integrative framework for action

BACKGROUND

The scale-up and sustainability of social innovations for health have received increased interest in global health research in recent years; however, these ambiguous concepts are poorly defined and insufficiently theorised and studied. Researchers, policymakers, and practitioners lack conceptual clarity and integrated frameworks for the scale-up and sustainability of global health innovations. Often, the frameworks developed are conceived in a linear and deterministic or consequentialist vision of the diffusion of innovations. This approach limits the consideration of complexity in scaling up and sustaining innovations.

OBJECTIVE

By using a systems theory lens and conducting a narrative review, this manuscript aims to produce an evidence-based integrative conceptual framework for the scale-up and sustainability of global health innovations.

METHOD

We conducted a hermeneutic narrative review to synthetise different definitions of scale-up and sustainability to model an integrative definition of these concepts for global health. We have summarised the literature on the determinants that influence the conditions for innovation success or failure while noting the interconnections between internal and external innovation environments.

RESULTS

The internal innovation environment includes innovation characteristics (effectiveness and testability, monitoring and evaluation systems, simplification processes, resource requirements) and organisational characteristics (leadership and governance, organisational change, and organisational viability). The external innovation environment refers to receptive and transformative environments; the values, cultures, norms, and practices of individuals, communities, organisations, and systems; and other contextual characteristics relevant to innovation development.

CONCLUSION

From these syntheses, we proposed an interconnected framework for action to better guide innovation researchers, practitioners, and policymakers in incorporating complexity and systemic interactions between internal and external innovation environments in global health.

Using systems thinking to understand the scale-up and sustainability of health innovation: a case study of seasonal malaria chemoprevention processes in Burkina Faso

BACKGROUND

Scale-up and sustainability are often studied separately, with few studies examining the interdependencies between these two processes and the implementation contexts of innovations towards malaria prevention and control. Researchers and implementers offer much more attention to the content of innovations, as they focus on the technological dimensions and the conditions for expansion. Researchers have often considered innovation a linear sequence in which scaling up and sustainability represented the last stages. Using systems thinking in this manuscript, we analyze complex scaling and sustainability processes through adopting and implementing seasonal malaria chemoprevention (SMC) in Burkina Faso from 2014 to 2018.

METHODS

We conducted a qualitative case study involving 141 retrospective secondary data (administrative, press, scientific, tools and registries, and verbatim) spanning from 2012 to 2018. We complemented these data with primary data collected between February and March 2018 in the form of 15 personal semi-structured interviews with SMC stakeholders and non-participant observations. Processual analysis permitted us to conceptualize scale-up and sustainability processes over time according to different vertical and horizontal levels of analysis and their interconnections.

RESULTS

Our results indicated six internal and external determinants of SMC that may negatively or positively influence its scale-up and sustainability. These determinants are effectiveness, monitoring and evaluation systems, resources (financial, material, and human), leadership and governance, adaptation to the local context, and other external elements. Our results revealed that donors and implementing actors prioritized financial resources over other determinants. In contrast, our study clearly showed that the sustainability of the innovation, as well as its scaling up, depends significantly on the consideration of the interconnectedness of the determinants. Each determinant can concurrently constitute an opportunity and a challenge for the success of the innovation.

CONCLUSION

Our findings highlight the usefulness of the systemic perspective to consider all contexts (international, national, subnational, and local) to achieve large-scale improvements in the quality, equity, and effectiveness of global health interventions. Thus, complex and systems thinking have made it possible to observe emergent and dynamic innovation behaviors and the dynamics particular to sustainability and scaling up processes.
