Context: Despite the demonstrable benefits of many healthcare innovations, embedding research findings into practice has been slow and sporadic. Many implementation frameworks exist, however most have been criticised for not having a strong theoretical underpinning. This study addresses this gap by reviewing the current models to propose a new, theoretically driven framework for change management and translation. Methods: This study is reported in two parts. In part 1, a systematically-based literature review was undertaken. Following this, part 2 included conducting focus groups with academics to verify the model and provide feedback on the new framework. Findings: The gaps in current implementation frameworks identified include deficiencies in the areas of individual and social behaviour, participatory action, operationalisation and evaluation of the frameworks. The Quality Implementation Framework (QIF) was used to provide the basis to develop a robust extended model, which addressed those areas that were identified as deficient in the current frameworks. By combining the best parts of extant models with a translation and implementation foci, we developed the PARTI model that is underpinned by commitment to change (Ying) and change fidelity (Yang) at each of its four stages, which included a behavioural questionnaire and implementation checklist. PARTI stands for Participatory Action Research, Translation and Implementation. Conclusions: The implementation of change in healthcare delivery is difficult and demanding, and healthcare managers look to change frameworks for guidance. The PARTI model has been developed to provide a systematic approach to implementing changed practices that is repeatable, reliable and scalable.
