Adaptation reconceptualized: "retrofitting" ongoing organizational activities with essential elements of evidence-based interventions
Implementation Science volume 10, Article number: A35 (2015)
Evidence-based interventions (EBIs) are sometimes implemented in contexts where ongoing program activities overlap with EBI components. As part of a comprehensive cross-site evaluation, we examined the grant-funded implementation of the EBI "Yes We Can" (YWC), a medical-social model for pediatric asthma care coordination, in four distinct settings. Assessment indicated that some sites already had in place one or more activities that were similar to YWC components. We examined why and to what extent organizations "retrofitted" existing activities to align with YWC core elements, and how retrofitting influenced implementation and maintenance.
YWC essential elements were identified through a literature search and interview with the developer. We obtained information about ongoing organizational activities and subsequent adaptations from in-depth interviews with site leaders and field staff, in which factors affecting implementation  were also probed. Detailed interview notes were coded and analyzed, using NVivo.
The extent of retrofitting ranged from one extreme, where the EBI was adopted where no similar activities existed, to the other, where a well-established, successful program was improved by adopting select components of YWC. Key informants noted the value of keeping "what already works" in their unique context while enhancing ongoing services by adding EBI components. Factors affecting implementation highlighted the conditions that make retrofitting a rational and feasible approach; e.g., a flexible, complex intervention that allows for significant adaptations and the opportunity to capitalize on existing political support for program activities. In this small sample, sites that retrofitted ongoing activities were better able to maintain EBI components after funding ended.
Retrofitting reflects the reality of how some EBIs are adapted, and may promote successful maintenance. Future research can explore systematically how retrofitting affects other key outcomes such as adoption, reach, and effectiveness.
