Implementation science has evolved in recent years due to the rapid advances of evidence-based healthcare. Several frameworks and theories of implementation have been published and are in use by researchers and healthcare practitioners to support the embedding of evidence into practice. An overarching theory summarizing the key elements of the various existing frameworks has been described by Damschroder et al. The authors have identified five key domains that overlap in the available theories and existing models using a snowball sampling approach to identify the various constructs across the published theories. The five major domains identified are the intervention characteristics, outer setting, inner setting, characteristics of the individuals involved and the process of implementation. The advantage of such amodel is that it provides a pragmatic outline for tackling complex multi-level interventions to ensure effective implementation. In spite of our increased knowledge of the various strategies of evidence-based practice and implementation frameworks, there is still a huge gap that exists regarding the sustainability of health interventions in practice. More recently, implementation projects included various strategies to ensure the sustainability of the interventions. Examples of these strategies include long-term action plans, tracking of program adoption, financial planning and mapping of the community where interventions are being implemented, among others. However, information about the success of these strategies is not easily identified due to the various methods used to measure effectiveness and shortened observation periods between data collection ending and the cessation of funding. Chambers et al. have proposed a Dynamic Sustainability Framework (DSF) that incorporates continued learning and problem solving, ongoing revision of interventions with a primary focus on fit between interventions and multi-level contexts, and prospects for ongoing development as opposed to reducing outcomes over time. Essentially, the framework focuses on a few key elements, which are the intervention, the context in which the intervention is delivered and
