Theories, Frameworks, and Models in Implementation Science in Cancer

This chapter describes implementation theories, models, and frameworks and justifies their systematic use to build understanding of implementation science across the cancer care continuum and, ultimately, facilitate stewardship of effective cancer care and spending across complex clinical and public health contexts. The chapter discusses several previously developed taxonomy and categorization schemes as well as resources to aid implementation researchers and practitioners in their cancer-related implementation science efforts. The importance of precision implementation using systematic theoretical approaches to coincide with precision oncology efforts and funding is also discussed. After providing concrete examples of theory, model, and framework use across the continuum from prevention to palliative care, relevant implementation science opportunities for collaboration, patient-reported outcomes research, de-implementation, and measurement are highlighted as future directions. A case is constructed for the systematic use of theories, models, and frameworks in implementation science and practice.
