Readiness for scale-up: lessons learned from the Public Health Agency of Canada's Innovation Strategy

Setting The Public Health Agency of Canada Innovation Strategy (PHAC-IS) funded the development and delivery of interventions that addressed priority population health issues over a 10-year period between 2009 and 2020. The design of the PHAC-IS funding program integrated the intentional effort of scale-up to increase the reach and impact of proven population health promotion interventions towards long-term, sustained impact benefit at individual, community, and systems levels. Intervention Recognizing that social innovation and adaptive cycles are necessary for effective scale-up, the PHAC-IS developed and applied a Scale-up Readiness Assessment Tool (SRAT) to assess the level of scale-up readiness of a funded project. Outcomes Development of the SRAT included identifying predictors of success for the scale-up of effective population health interventions, organized into eight common characteristics among projects that indicated scale-up readiness: (1) intervention evidence and evaluation, (2) reach and scale, (3) organizational capacity, (4) partnership development, (5) system readiness, (6) community context, (7) cost factors, and (8) knowledge development and exchange. Implications Although the SRAT was not a standalone decision-making rubric, it was a key part of a framework for review, consideration, and assessment for scale-up along a phased approach to funding. The development and application of the SRAT to measure readiness for scale-up provides insights into domains that can be used by funding organizations to inform scale-up decisions or for community organizations to assess their own readiness for scale-up.
